Squirting

Fig 9 3 A simple laboratory set-up for observing the casting process directly. The mould volume measures about 50 X 50 X 6 mm. The walls are cooled by putting the bottom of the block into a dish of liquid nitrogen. The windows are kept free of frost by squirting them with alcohol from a wash bottle every 5 minutes. 

In injection moulding, polymer granules are compressed by a ram or screw, heated until molten and squirted into a cold, split-mould under pressure (Fig. 24.3b). The moulded polymer is cooled below T, the mould opens and the product pops out. Excess polymer is injected to compensate for contraction in the mould. The molecules are oriented... 

Ixt .s talk about the pump efficiency. Imagine a small pump connected to a garden hose squirting a stream of water across the lawn. You could direct the How from the ho.se up into the air at about a 45-degree angle, and the stream would arc upward and attain its best distance of reach from the nozzle or launch point. The stream of water would attain a specific height into the air and a specific distance. The efficiency curve of a pump is seen as the trajectory or arc of a stream of water. When squirted from a hose, the elevation that attains the be.st distance, when plotted onto the pump curve, is called the best efficiency point (RHP). On the pump curve, it is seen as in Figure 7. ... 

Most plates are extruded in polypropylene which withstands temperatures of 80 to 85" C. Operating at higher temperatures will warp the plates and leakage or even squirts can be dangerous at such high temperatures.

The tank is typically about sixteen inches in diameter and about four to five feet tall. The top of the tank is domed upward and the bottom of the tank is also domed upward in a concave manner. The outside of the tank is insulated with a polyurethane foam insulation that is squirted into the gap between the tank and a thinner sheet metal jacket. The polyurethane is made of two different components that react and harden when mixed. Included in the mixture is a blowing agent that causes the polyurethane to expand in a foam-like manner. Prior to about 1980, water heaters were insulated with fiberglass insulation. The foam insulation process was developed to allow automation and increased manufacturing speed and reduced costs. A side benefit was improved insulating ability leading to a slight increase in efficiency. 

Air leaks are another source of trouble in the MS. A simple method of leak detection is to squirt a small volume of acetone on flanges and other areas where leaks could occur. Caution is advised not to use this procedure near hot surfaces because of the flammability of acetone. A second way to test for small leaks is to tune the MS to m/z 40 and to use argon to test for leaks. The m/z 40 peak will increase if argon enters the source. Helium m/z 4) is a better choice, except when helium carrier gas is used in conjunction with the GC. A small stream of the gas is aimed at all seals where a leak can occur. If a leak is detected at a seal, it can sometimes be stopped by tightening the seal, but it is better to replace the seal than to overtighten it.

They said, We re going to make you a real margarita, a Mexican margarita, Ms. Torres recalled. It was Squirt, tequila and lime. 

Pour the tequila over ice in a tall highball or Collins glass. Add the lime juice. Add Squirt or a substitute. Stir and garnish with a slice of lime. 

Fluorescent lamps are manufactured by squirting a suspension of phosphor particles in an ethyl cellulose lacquer upon the inner surface of a vertical glass tube. Once the lacquer drains off, a film of peuticles is formed. The lacquer is then burned off, leaving a layer of phosphor particles. Electrodes are sealed on the tube is evacuated Hg and inert gas is added and the lamp ends are added to finish the lamp. Lamp brightness and lifetime are dependent upon the particle size distribution of the phosphor particles. The number of small particles is critical since they are low in brightness output... 

Handle the nylon with extreme caution so that any small bubbles of occluded liquid that form do not burst and squirt liquid on skin or clothing.

Other ants, like the carpenter ant, are incapable of stinging, but that does not stop them from biting and then squirting formic acid into the wound. In this case, because the venom is not injected, a baking soda paste can quickly neutralize the venom and ease the pain. Fire ants, however, have toxic alkaloid venom. Regardless of whether the ant that bites or stings you has acidic or alkaline venom, however, one thing remains the same—it hurts ... 

Nomura and Ogata provided the first evidence that tunicates can produce PGs [17]. Using a rat stomach fundus bioassay, Halocynthia roretzi tissues were shown to possess low levels of PGs. The testes showed higher levels (9 ngg-1 wet tissue) than ovary and muscle tissue. The sea-squirt Styela clava did not show PGs by this method. No structures were determined in this work. Reexamination of the ability of H, roretzi to produce PGs was carried out by Ogata and coworkers [19]. Incubation of selected tissues with 14C-labeled eicosa-8,11,14-trienoic acid and subsequent isolation of PGE and PGF fractions after addition of carrier showed the branchial tissue to have the highest conversion levels. Quantitation was done by LSC. Using a TLC radioscanner, the authors determined that fractions with metabolites similar to PGE and PGF...

There s a pressure device on the system because the sample must make contact with the diamond. If you squirt a liquid on the diamond, it makes perfect contact if you sprinkle a powder on the diamond, powders don t make perfect contact. To make perfect contact with a powder, take two to three turns of the pressure device. You just take a little piece off the intended sample. You could actually break a pill, and the dust that falls off is enough for the analysis. You must make contact and the pressure device squashes the sample down to make contact. If you sprinkle a little piece of powder on the diamond, you wouldn t get spectra. Squash that powder, and you can actually see the powder being squashed when you use the little video camera. You can immediately see the spectrum show up. You have all the pressure you need do not get worried about crushing the sample as you are making it touch the diamond.
