Title: Refrigerators
IPC: H02N3/00
Filed: 1972-03-13
Abstract: 1423825 Refrigeration NATIONAL RESEARCH DEVELOPMENT CORP 29 March 1973 [13 March 1972] 11524/72 Heading F4H [Also in Division H2] A refrigerator utilizing an electrogasdynamic generator comprises a thermally insulating chamber 1 from which heat is extracted by a heat exchange gas carrying fine electrically chargeable particles which gas is cooled in an electrogasdynamic expander 2 within the chamber and passed thereafter in a circulatory path to a compressor 4 for recirculation. The circulatory path includes a heat exchanger 3 between the chamber and compressor to extract heat from the gas passing back to the expander after cooling in a heat exchanger 5, and the compressor may comprise an electrogasdynamic compressor. The electrogasdynamic expander comprises generating sections each formed by charge emitting and collecting electrodes 7, 8 Fig. 2 and a field is applied along each section to oppose the flow of gas-borne particles which are negatively charged at electrode 7 by a corona discharge. As a result a pressure drop in the gas occurs in passing along the path which leads to a temperature drop. The electrodes are surrounded by earthed conducting screens 11, 9 respectively the screen 9 about the collector electrode 8 being by means of a resistive lead of a magnitude such that the potential developed on the screen 9 is greater than that of emitter electrode 7. The electrically charged particles may comprise liquid particles, e.g. formed by condensation of the carrier gas at the entrance to the electrogasdynamic expander and the gas may comprise helium and hydrogen, or nitrogen and carbon monoxide.

Title: Fluid operated prime mover
Inventor: STRAND GEORGE FREDERICK
IPC: F01D17/06
Filed: 1958-04-11
Abstract: 848,526. Centrifugal governors. ROTOL Ltd. April 3, 1959 [April 11, 1958], No. 11650/58. Class 57. The centrifugally operated valve for controlling the flow of fluid through a prime mover (such as a turbine or swash-plate motor) having a motor-driven shaft 4 comprises two relatively movable members 6, 23 rotatable with the shaft and having ports 21, 22, 24 which co-operate with inlet and outlet galleries 11, 14 in the valve housing 2 and centrifugal control means arranged to produce relative rotation of the members 6, 23 so as to control the rate of fluid flow. As shown applied to a compressed air turbine, the valve member 23 is coupled to the shaft 4 by a torsion spring 25 connected at one end 30 to a threaded sleeve 31 screwed to the end of the shaft and at the other end 26 to the valve member. The latter member is provided with two abutments 56, 57, Fig. 3, which engage with bearings 50, 51 carried by flywieghts 40, 41 pivotally mounted in the rotor 5 of the turbine; the loading of the flyweights is effected by rotating the screwed sleeve 31 so as to increase the torsion of the spring 25 and clamping it in position by a screw 33, the threads of the sleeve and screw being of opposite hand in order to prevent loosening of the screw due to the bias of the spring. The valve member 6, which forms part of the rotor, is provided with two axially spaced rings of inlet and outlet ports 21, 22 which are interconnected, as shown in Fig. 1, by recesses 24 formed in the member 23. In operation, compressed air is fed into the inlet ports 21 via an annular gallery 14 formed in the turbine stator housing 2, circumferentially spaced ports 13 and an annular inlet manifold 11. The air then passes into the recesses 24, through the outlet ports 22 to act on blades 3 and thereby rotate the rotor 5. Above a predetermined speed of the latter, governed by the loading of the spring 25, the flyweights move outwardly against the resistance of the spring and, through the engagement of the bearings 50, 51 with the abutments 56, 57, rotate the valve member 23 relatively to the sleeve 6 so as to close the ports 21, 22 and thereby reduce the speed of the rotor; in order to increase the range of relative movement between the fully open and fully closed positions of the ports 21, 22, the latter are circumferentially staggered relative to the recesses 24. In a modification (Fig. 4, not shown) the recesses 24 and ports 21, 22 are replaced by an arrangement of ports which causes the flow of fluid between the valve member 6, 23 to be in an axial direction instead of a radial direction. Specification 730,560 is referred to.

[Also in Division C1] Saline solution is introduced into extraction column 1 by pipe 4 and contacts solvent fed from tank 3, the contact being aided by agitator 8 and a fin 6. The water-loaded solvent is collected in tank 10 and the concentrated brine is discharged into settling tank 3. The loaded solvent taken from reservoir 10 is washed with prewater and is fed to separating column 2 by distributor 5 and as it passes up the column it is heated by the brine coil 11 and through the heat transfer wall of the extraction column. This separates out the fresh water which is removed through pipe 16. The column is pulsed by means of compressed air connected at 18. The solvent heated by resistor 22 and is discharged into the tank 3 for recycling. Separation of the brine is accomplished in the settling tank and this is fed before discharge to pipe 11.

As shown in Fig. 2. a turntable 13, supporting a series of hydraulic presses, is carried by a hollow shaft 25 driven through bevel gears 20, 21 from a shaft 22 driven through a pulley 90 and clutch 91. The water-supply pipe passes upwardly through the shaft 25, and is connected by a sealing plug 31 to a nozzle 27, rotating with the table, furnished with branch pipes 35 supplying the presses with pressure and cooling water. Steam is supplied to the presses through a nozzle 37 and branch pipes 38, and exhausts through pipes 39, header 40, pipe 41, sleeves 42, 43, and pipe 44. Waste water passes to a trough 53. Each press is furnished with valves controlling the steam, and the pressure and cooling water, which valves are operated by cams rocked by levers furnished with rollers engaging stationary cam rails 17, 18, 19. The machine may be stopped from either the loading or unloading positions by operating one of a pair of similar levers 99 mounted on a shaft 98 connected through an arm 97 and link 96 to a lever 94 controlling the collar 93 of the clutch 90. Simultaneously with the disengagement of the clutch, a brake shoe is applied to the table 13.
