In a dual-hose Venturi Series dry ice blasting system, an ejector type nozzle, similar to a conventional abrasive media blasting nozzle, is used to combine the compressed air stream with the dry ice particle carrying vacuum stream created by the ejector. In Cold Jet's single-hose Radial Feed Series dry ice blasting systems, the dry ice pellets are mechanically fed into the air stream. No energy is wasted creating a vacuum to pull the pellets through a separate line.

AIRLUX portable air conditioners have only one air exhaust hose as oppose to some other models that have two air hoses, one for air intake and one for air exhaust. A single hose unit will take air from the room that it is in and return most of that air back into the room as cold conditioned air. A dual hose unit works by taking in air from the outside through one of its hoses and using that air to cool the unit - and then that hot air is expelled through the exhaust hose.

Single Hose - draws indoor air for both front cold air output as well as exhaust air (used to cool compressor). Percentage of the air taken in is used to cool the condenser. As this air is exhaust out, it creates a negative air pressure. Air is continuously seeping in from adjacent rooms to replace the exhausted air. Dual Hose - draws indoor air for front cold air output and draws outdoor air for exhaust air (used to cool compressor).

The advantage of a single hose system is the easy handling. The dry ice pellets are transported and accelerated with high air pressure in one hose. The disadvantage is that the dry ice and high air pressure come together very early. The pellets break on their way to the gun causing lower cleaning performance. To compensate for this lower performance more dry ice used. A double hose system consists of one hose with the air pressure for the acceleration and one hose for the dry ice transportation.

Size. Dual Layered Disc are Twice the size of a Single Layered Disc. Dual layered disc's also cost more.

A single source selector (ISM models) accepts input from one audio source (receiver/amplifier) and distributes audio output to a number of zones or speakers. However, a dual source selector (DSSM, VSS models) accepts inputs from two separate amplifiers/receivers and allows the user to select the program from one of the two sources for each zone output. With dual source selectors, the audio programs from both amplifiers cannot be selected at the same time for any zone output.

Depending on each application, either single-rate or dual-rate springs are available. Dual-rate springs are just that-- a spring set with two separate rates. This is done with a short spring stacked on a longer spring. As both springs collapse they result in a soft, or initial, rate. The spring set will retain this initial rate until the short spring stops compressing. At that point, the spring rate "crosses over" to the stiffer, or final, rate.

It is easy to confuse a dual voice coil sub as a better subwoofer, but that’s not the case. You will get the same output from either sub when used in the right application. Both sets of terminals must be wired up when using a dual voice coil subwoofer. Your amp and the number of subs will determine which subwoofer you would want. For example, if you had a TA5601 amplifier and wanted to run a pair of 12s, you would want single voice coil 4Ω woofers.

Single power source modules needs just one 3 - 5V power supply for the entire module. The module contains an inverter that supplies the operating voltage for driving the liquid crystal. Dual power source modules need a 3- 5V power supply for the LCM and another power supply to provide the Vop for the liquid crystal.

The difference between dual track and single track is that single track holders hold one line of tags while dual track holds two lines of tags. Click here to view E-Z tags and holders.

Answer: Acquinox? dual flush toilets will save you over 6,000 gallons of water per year for a family of 4. The Dual Flush system gives you the best of both worlds: The Low Flush uses less than 8/10s of a gallon of water while the Normal Single Flush uses 1.58 gallons ? still within conservation limits.

ALSO SEE THE SUPPORT SECTION FOR A TUTORIAL REGARDING SINGLE AND DUAL CONVERSION. The single conversion receiver uses a single Local Oscillator at 455 kHz removed from the transmitter frequency to achieve narrow band and high sensitivity. A dual conversion receiver has two local oscillators. The first L.O. is 10.7 MHz removed from the transmitter frequency to overcome the one weakness of single conversion; i.e., the lack of rejection at the image frequency.

Working Assets Wireless customers enjoy the best wireless coverage available through Sprint, providing the largest all-digital, all-PCS nationwide network. The network covers more than 4,000 metropolitan areas and communities across the country. Digital technology allows your call to be processed and carried on the network more efficiently than an analog network. Digital technology also ensures greater call security than analog technology.

A booster is a radio frequency amplifier that will do two things: it will take the signal that is transmitted by the cell phone when a call is engaged and use electrical energy to make it stronger and send it out through the antenna to the tower. The booster will also receive the signal that was generated by the tower, through the booster antenna, use electrical energy to amplify the tower signal and send it to the phone.

The single-action clamp is a one piece assembly - both the clamp and the base are attached to the turntable. Unfortunately, the brake of the single-action clamp wears out with frequent use, requiring regular maintenance. In 1990, the Wilson Sporting Goods Co. introduced its Pro Staff (Prestige) stringing machine, which was manufactured in Taiwan. It utilized the single-action swivel clamp assembly, and it had brake problems (as mentioned above). Wilson Sporting Good Co.

Many people prefer to subscribe to this list in "digest" form. This means that all of a day's messages are combined in a single email message with a table of contents. Due to network traffic and other factors, digests aren't received at the same time each day or even at the same time by all subscribers. It's not unusual for digest posts to be separated by more than or less than 24 hours. Occasionally, two digests may arrive on the same day.

If your hose don’t come with a tag (which goes in the back), there are two telltale signs of the back of hosiery. One is the heel of the foot that can be seen and assures they are on properly. Occasionally, there will be a longer seam or thread that sticks out higher in the back than the front. Sometimes, there is no way to tell the front from the back and therefore it does not matter which way they go on.

Annular hose construction is a series of full 360-degree corrugations consisting of a root radius, sidewalls, and a crest radius. Each convolution is a complete entity unto itself. Helical hose construction is a single, continuous corrugation that travels along the longitudinal axis of the hose. Some of our competitors list maximum working pressures based on calculations performed using the material properties of raw steel strip.

The single-side foil is great for acoustic applications where sound can be absorbed into the natural fibers. The dual-sided foil provides an excellent radiant heat barrier to resist heat flow.

DVI has the ability to employ two links. Each link is comprised of three data channels for RGB. Each link has a maximum bandwidth of 165 MHz. Dual link has a maximum bandwidth of 330 MHz. Dual link supports resolutions up to 2048 x 1536. Currently, most equipment is Single Link.

It might look like a cleaner configuration for pictures, but is that what you're buying it for? (Excuse the answering a question with a question) (Also it's less expensive to provide only one hose.) Top

If a child is dually enrolled, s/he may participate in all academic and extracurricular activities offered at the district on the same basis as a regularly enrolled child. A child enrolled in a HSAP must also dually enroll to participate in academic and extracurricular activities.

the ohm load is the total resistance that your amp is seeing when wired up to the subs/speakers. In general, lower ohm loads will mean that your amp will be putting out more power. However, you need to make sure that your amp is stable at that ohm load or you will cause significant damage. The ohm load can be changed by wiring the subs differently, ie. Parallel vs. series. To determine ohm load when wired in series, the ohm load = Resistance1 +Resistance2+Resistance3+....

In a two-hose system, the dry ice travels in one hose and the high pressure air in another. The two are not mixed until just before the pellets exit the end of the nozzle. The primary advantage of a two-hose system is simplicity. In a one-hose system the pellets and air are mixed together in one hose at an air lock and travel the complete length of the hose.

You can complete a dual major (more than one course of study) by completing the requirements for each major. At graduation time, you will have both majors listed on one diploma (example: Bachelor of Arts, Communication and Sociology). Please note that if you are completing a Bachelor of Science degree and a Bachelor of Arts degree, you may only complete this as a dual baccalaureate degree.

Weather permitting, weekly riders average 3 to 4 rides per week which last approximately 30 minutes each. The day riders go out for the number of days they purchased.

The Acnelamp has three configurations depending on how far your acne is spread out. The single head unit is typically used for people that have acne on one spot. The two and three head are perfect for getting the sides of your face and front of your face at the same time. Each lamp has the same power per centimeter, but cover different areas. Having acne all over your face does not mean you absolutely need a three head lamp.

Joint-Stereo - This method of encoding combines duplicate (or "perceptually similar") information from the Right and Left channels in an effort to most efficiently compress the file. This way the duplicate information is only encoded *once* instead of twice (one time for each channel) and allows for more bits to be allocated to the other non-duplicate information.

A double major means that a student receives one diploma that covers two majors. Students who choose two majors in business, such as finance and management, will receive only one diploma but both major fields of study will be noted on the transcript. A dual degree means that a student receives two diplomas for two majors. Students must earn a minimum of 150 credit hours, 90 of which are junior/senior-level, to meet dual degree requirements.
