Abstract: The invention concerns a method of and an apparatus for continuously desalinating water by reverse osmosis, in particular desalinating sea water, wherein salt water is introduced under a first pressure by means of a delivery pump into a pressure compensating device, salt water is continuously introduced from the pressure compensating device at a second increased pressure into a membrane module and separated therein by means of a membrane into desalinated water and concentrated salt water, and the concentrated salt water discharged from the membrane module is continuously introduced under approximately the second pressure into the pressure compensating device and used there for acting with approximately the second pressure on the salt water introduced into the pressure compensating device and for introducing the salt water into the membrane module. In order to avoid disturbances in operation and possibly damage to the membrane because of a reduced flow over the membrane surface, it is provided in accordance with the invention that a continuous flow of the salt water introduced into the membrane module is maintained over the surface of the membrane by means of salt water discharged from a reservoir.

Abstract: The invention comprises an improved pressure transfer module having, in one embodiment, two double-diaphragm pumps each having its diaphragms connected to one another by a respective drive shaft for reciprocating motion. Spool valve assemblies are mounted directly on the connecting shafts of each pump and arranged to maintain the operation of the two diaphragms of the pumps 90.degree. out of phase in that each such assembly constitutes pressurized water control valves for the other pump. The two pumps are mounted with the drive shafts at 90.degree. to one another, and arranged to pump in sequence so that a complete pumping cycle comprises four pumping strokes, one every 90.degree.. To insure reversal of motion of the shafts in proper phase, the invention includes either two, meshed square cams and cam surfaces formed on respective shafts connecting the pumping surfaces, or a floating crankshaft with each end pivoted in one of the connecting shafts.

Abstract: An energy recovery pump-motor including an energy recovery pump and a mixed-phase motor for replacing conventional valves in fluid circuits such as an absorption refrigeration system. The energy recovery pump pressurizes a first liquid by recovering flow work energy from a second liquid. The mixed-phase motor recovers flow work energy and expansion energy from a high pressure, saturated third liquid and transfers the energy along a shaft to the pump to aid in pressurizing the first liquid. The energy recovery pump is shown in a single effect absorption refrigeration system, while the pump-motor is shown in both single effect and double effect systems.

Abstract: The invention disclosed relates to the art field embracing positive displacement reciprocating compressors of the type featuring hydraulic drive, and sets out to simplify the construction of such units, rendering them more functional at the same time. Four coaxial bulkheads are adopted, set apart one from the next by three cylinder barrels, and three pistons which are mounted to a common rod and reciprocated thus, each in its respective barrel; the central piston and barrel are of either greater or smaller diameter than the remainder. Hydraulic oil from a power pack driving the compressor flows alternately into chambers which are occupied by the rod, and bounded at one end by one of the pistons of smaller or greater diameter.

Abstract: The sealing surfaces of a coke oven door are cleaned with high-pressure fluid by a hydraulically operated high-pressure piston pump which displaces either a hot or a cool conveyed media ladened with solid particles such as a coal mass and a fluid for cleansing the sealing surfaces of the coke oven doors and door frames. The pump includes a closed pump cylinder having an inlet and outlet valve for a conveyed medium at both ends of the cylinder and a partition dividing the cylinder. Inlet and outlet valves for hydraulic fluid are located in the cylinder on each side of the partition. An inner double piston is axially movable to and fro with the cylinder and comprises two output piston portions with a piston rod connected to each portion and located between them guided on bearings in the cylinder. A delivery space is formed between the piston portions and each end of the pump cylinder and the respective delivery spaces at each end simultaneously and oppositely decrease and increase during an operation. The hydraulic space is formed between the piston portions at each side of the partition and the hydraulic space also simultaneously and oppositely increase and decrease during operation. The pump is connected to a coke door cleaning apparatus for the purpose of cleaning an annular sealing surface. The apparatus includes a generally rectangular annular sealing surface trackway around the sealing surfaces of the door and a support structure adjacent the sealing surface having a sliding support surface trackway adjacent the door. A sliding support moves over the support surface. A nozzle lance is carried on the support and has an end with a nozzle directed at the sealing surface and an opposite end with a cleaning liquid connection through a hose to the high-pressure piston pump.

Abstract: A fluid intensifier characterized by a bistable control mechanism which "remembers" the point in the operating cycle it is in. The bistable control mechanism controls the movement of a reciprocating assembly located within a main cylinder assembly. The reciprocating assembly co-acts with a stationary assembly to pump high pressure fluid from the main cylinder assembly. The fluid intensifier can be powered by an interruptable fluid source since the fluid intensifier will resume operation from its stopping point when fluid pressure is reapplied.

Abstract: A fluid supply system includes a pump body having a main bore connectible through inlet check valves to draw secondary fluid from a first fluid reservoir and through outlet check valves to supply it to a secondary fluid function upon reciprocation of a free piston in the main bore. The free piston includes a pair of coaxial driving pistons on either side which extend into main passages which are alternately connected to a pressurized primary fluid source to cause reciprocation of the free piston. A first spool valve which responds to the completion of a free piston stroke activates a second spool valve which changes the primary fluid source connections to the driving pistons.
