Other single-stage hydrogenation processes are the Exxon Donor Solvent Process, the Imhausen High-pressure Process, and the Conoco Zinc Chloride Process.

High-pressure air, compressed air or nitrogen, is stored in the tank at a very high pressure, typically 3000 – 4500 psi.

They were carpeted, but made for pumps and congress gaiters, not the great clodhoppers he wore.

So you sit in the car and listen to the air run out and listen to the rain and see the mud in front of the headlights, waiting for you, for your new spectator pumps, waiting for you to squat by yourself out there in your tight skirt, crying and afraid and trying to get that damned son-of-a-bitch tire off, because that is being an old maid too, if you happen to drive a car, it is changing the tire yourself in the night, and in the mud and the rain, hating to get out in it but afraid to stay and afraid to try to walk out for help.

On contraction, these alternately pass the blood to a single ventricle which pumps it both into both the systemic vessels ( which service the body at large ) as well as the pulmonic vessels ( which return to the lungs for oxygenation ).

The distinctive “ double-pull ” format that typifies most of these songs — also at times used, with slight changes, for pumps, windlass, and capstan, too — was a later development that appears to owe much to African-American work songs.

The barge and canal system contended favorably with the railways in the early industrial revolution prior to around the 1850s – 1960s for example, the Erie Canal in New York State is credited by economic historians with giving the growth boost needed for New York City to eclipse Philadelphia as America's largest port and city but such canal systems with their locks, need for maintenance and dredging, pumps and sanitary issues were eventually outcompeted in the carriage of high-value items by the railways due to the higher speed, falling costs, and route flexibility of Rail transport.

Furthermore, Cornell's system pumps significantly less warm water back into the lake than others further north which have been operating for decades, including the coal-fired power plant on the eastern shore.

: This term is used both for conventional p – n diodes used to monitor temperature due to their varying forward voltage with temperature, and for Peltier heat pumps for thermoelectric heating and cooling .. Peltier heat pumps may be made from semiconductor, though they do not have any rectifying junctions, they use the differing behaviour of charge carriers in N and P type semiconductor to move heat.

Due to backstreaming, oil diffusion pumps are not suitable for use with highly sensitive analytical equipment or other applications which require an extremely clean vacuum environment, but mercury diffusion pumps may be in the case of ultra high vacuum chambers used for mercury deposition.

Agriculture is the leading occupation for the residents of the state, the flat arable land irrigated by submersible pumps and an extensive canal system.

A good example is AID Foundation International in the Philippines, who won an Ashden Award for their work developing ram pumps that could be easily maintained for use in remote villages.

These pumps should be distinguished from other penis pumps ( supplied without compression rings ) which, rather than being used for temporary treatment of impotence, are claimed to increase penis length if used frequently, or vibrate as an aid to masturbation.

Plunger pumps with a larger number of plungers have the benefit of increased flow or smoother flow without a pulsation dampener, and a drawback is the increase in moving parts and crankshaft load.

The low density of hydrogen further affects the design of the rest of the vehicle — pumps and pipework need to be much larger in order to pump the fuel to the engine.

Using sensors and pumps, a relatively small amount of energy ( i. e. that used to power a pump and controller ) can harvest a far larger amount of available thermal energy by switching on as soon as a useful temperature differential becomes present.

In electrically powered heat pumps, the heat transferred can be three or four times larger than the electrical power consumed, giving the system a Coefficient of Performance ( COP ) of 3 or 4, as opposed to a COP of 1 of a conventional electrical resistance heater, in which all heat is produced from input electrical energy.

Hospital grade pumps are larger and intended for multiple users.

Electric breast pumps are larger than manual ones, but portable models are available ( e. g. in a backpack or shoulder bag ) that allow the mother to transport the pump.

The larger outlet is known as a " steamer " connection ( because they were once used to supply steam powered water pumps ), and a hydrant with such an outlet may be referred to as a " steamer hydrant " although this usage is becoming archaic.

On US market versions the larger engine sacrificed some of its performance from 1968 on, through the use of smog pumps and other modifications to comply with federal emission control requirements.

It is principally used for rural electrification, but also finds use for larger isolated loads such as water pumps, and light rail.

Versions designed for use in trucks and school buses were known as " FT ", an acronym for ' Ford-Truck ', and differed primarily by having steel ( instead of nodular iron ) crankshafts, larger crank snouts, different distributor shafts, different water pumps and a greater use of iron for its parts.

This called for pumping machinery and apparatus, and as greater depth was attained, larger pumps were demanded.
