Fly back

When constructing a manometer of the type shown in Fig. 12(c), it is impor tant to apply a very high vacuum (e.g., with a Hy-Vac pump) to the manometer while the mercury in the left-hand (sealed) limb is heated until it boils unless this is done, traces of air will remain in this limb and cause inaccurate readings. During a distillation, the tap I should be kept closed except when a pressure reading is being taken if it is left open indefinitely, a sudden default by the distillation apparatus or by the pump may cause the mercury in the sealed limb of G to fly back and fracture the top of the limb. 

Most Mossbauer spectrometers use triangular velocity profiles. Saw-tooth motion induces excessive ringing of the drive, caused by extreme acceleration during fast fly-back of the drive rod. Sinusoidal operation at the eigen frequency of the vibrating system is also found occasionally and... 

Well, it looks like there is nothing here for me. I m planning to fly back to Bogota." "Thank God," thought I. 

Super Bee flies back and forth between the speeding trains... 

The Problem How far does a bee travel if it flies back and forth between trains that are approaching each other on the same track — one train traveling at 60 mph and the other traveling 75 mph — if the bee flies at 90 mph and, when it started this journey, the trains were 648 miles apart ... 

Flows of purified gases, scrubbed over molecule sieves, are passed into the DMS analyzer at flows of 0.3-1.2L/min usually with a mass flow controller. Pressure is near ambient however, DMS analyzers can operate at reduced pressures with scaled values of E as expected with E/N. The electronics of the DMS analyzer are based on a fly back transformer to give the RF waveform. 

Although I had been thinking about nothing else for weeks, I still had not decided whether to fly back to Indiana or take the train. 

The pelican has perhaps the most unusual bill in the bird world. It is quite long—18 in (46 cm) in some birds— with the top part, or mandible, flat, narrow, and quite stiff. The bottom part has a solid upper edge surrounding a pouch of skin that can stretch almost endlessly to hold great quantities of fish. This soft, flexible tissue extends down onto the neck. The birds do not fly back to their nests with food in the pouch. They would not be able to keep their balance in flight. Instead, it serves as a net to catch fish. Up to 2 gal (7.6 1) of water can be taken in and then forced out through the closed mandibles, leaving the eaptured fish behind. They are then swallowed. 

After your two weeks of in-class training, you will be flown back home to your territory. You will work your territory for a month or two and then fly back to the home office for a couple more weeks of sales training. You will then learn how to successfully sell the products. 

Although the Pocket Rocket is far more powerful than a regular slingshot, it has one drawback. The nibs which connect the leather strap which holds the PR to the wrist are not fixed. In use, the nibs tend to work off and the PR can fly back and clobber you in the mouth. Work the nibs off, fill them with epoxy and put them back. That way the PR will never come apart). 

Meanwhile, the English and French have been fighting for global dominance directly and by proxy for over 100 years. The phlogiston controversy gives them a fresh field for rivalry. Volleys of rhetoric fly back and forth across the Channel. Richard Kirwan, a viriolic Irishman, attacks Antoine (in print). Marie translates Kirwan s work—it provides Antoine with just the ammunition he needs and he... 

If he has to fly back to Xingu he may well kill everyone on board," the minister protested. "The plane could be downed in the ocean."... 

That was what had made him argue with the military controllers. Processor glitches were an acceptable menace there was so much redundancy built into the plane s electronic architecture it could survive an almost total shutdown but power loss was in a different hazard category altogether. Chapman Adkinson had already decided that if they did try to force him to fly back over the ocean he was going to ditch there and then, and to hell with the penalties they d load into his licence. The biohazard in Xingu couldn t be that lethal, surely ... 

A restless fly [8]. Two cyclists begin biking simultaneously, each in the direction of the other. One sets out from Columbus, Ohio, the other from Cleveland, Ohio. When the two cyclists are 80 km away (from each other), a fly lands on the shoulder of one of the cyclists, flies to the other cyclist, and then flies back. The restless fly goes back and forth until the cyclists cross paths, then... 

Frame scanner, which scans the beam vertically and forms frames of horizontal scan lines. The frame scanner cycles 50-120 times per second. A galvonometer-based scanner is typically used in conjunction with a mirrored surface. Because the mirror must fly back to the top of the screen in less than a millisecond, the device must be small and light. Optical element are used to force the horizontally scanned beam into a small spot on the frame scanner mirror. 

When the power switch Q1 opens, which is referred to as the off time (denoted by tofr)> the inductor voltage reverses polarity, and the output side (the right-hand end) flies back above the input voltage and is clamped by diode D1 at the output voltage. 

The power switch Q1 then turns off and the secondary of the switching transformer flies back above the output voltage and is clamped by diode D1 at the output voltage. The energy stored within the transformer is then transferred to the secondary circuit. The secondary current then begins to linearly ramp downward until the energy within the transformer core is completely depleted. This is shown as t > in Fig. 10.46 (see also Fig. 10.47) and is described as... 

Permethrin is marketed in spray (liquid or wettable powder), dust, ear tag, and pour-on formulations and is used in cattle being the target parasites horn flies, face flies, stable flies, back flies, houseflies, ticks, mites, and lice. Permethrin is available as ear tag formulation in combination with chlorpyrifos, and the target parasites are the same for permethrin.
