Title: Improvements in or relating to absorption refrigerating apparatus
IPC: F25B15/10
Filed: 1940-08-14
Abstract: 543,315. Lubricating electric motors. HOOVER, Ltd. Aug. 14, 1940, No. 13004. Convention date, Feb. 5. [Class 35] [Also in Group XIII]  In an inert gas refrigerating system means are provided for delaying the operation of the motor driven fan F in the inert gas circuit for a period after the heat supply to the generator B has been established. The rotor R<SP>1</SP>, Fig. 2 of the fan motor is immersed in lubricant which is solid at atmospheric temperatures and prevents rotation of the motor until the lubricant has been melted by the heat due to the current supplied to the motor; the circuit being closed by the thermostatic switch M which also establishes the full supply to the burner P<SP>1</SP> of the generator. The fan is arranged in the conduit A<SP>1</SP> for weak inert gas leaving the absorber A, and the discharge F<SP>1</SP> of the fan leads downwards to the lower end of the gas heater exchanger H so as to prevent flow of any liquid from the exchanger into the fan casing. The inert gas is forced through the outer conduit of the gas heat exchanger and may serve to drag or sweep liquid refrigerant from the condenser C upwards through the evaporator E, as described in Specification 504,374, [Group XIII]. The rotor of the motor has a small clearance in its casing, which is thin walled where covered by the stator and the bearings R<SP>2</SP>, R<SP>4</SP>, may be slack since the bath of lubricant will assist in centering the rotor when it is in action. A labyrinth trap is formed by fixed and movable baffles F<SP>3</SP>, F<SP>2</SP> around the fan shaft to prevent access of any liquid to the motor. The movable part serves to fling off liquid particles into the discharge pipe F<SP>1</SP>.

Filed: 1917-09-11
Abstract: 110,350. Nicholas, A. M. Oct. 13, 1916, [Convention date]. Rotary filters.-A rotary filter adapted for treating slimes and separating sugar juice from megass &c. comprises a peripheral hollow annulus 1 having a filtering-material 24 secured to its inner side, a flange 3 enabling a depth of liquid to be supported upon the filtering-medium at the lower part thereof, and means for applying a vacuum in parts of the annulus to abstract the filtrate and for applying fluid-pressure in other parts to expel the solids from the filtering- medium. The material to be treated is supplied by pipes 101, Fig. 2, to a launder 103 from which it runs down a grooved distributing-board 105 on to the filtering-medium. Sand or similar material may previously be sprinkled on the filtering- medium by an air ejector 77 which draws it from a hopper 80. The solids ejected in the upper run of the filter fall down a shoot 74. The drum is mounted on rollers 5, one of which is driven from a pulley 13 and rotates the drum. The annulus 1 is divided into chambers 19, Fig. 3, by partitions 18 placed obliquely to the axis of the annulus, and the corresponding sections of the inner shell 17 are each provided with tapering grooves 27 terminating in gutters connected by passages 28 with the chambers 19. Perforated metal sheets 26 cover the grooves 27 and support the filtering- cloths 24, which may be secured by wires 29 and staples 25, Fig. 5. Pipes 32, Fig. 12, connect each chamber 19 with an axial valve 36 by which the chambers are connected successively to the suction and pressure conduits; bends 32<a> in the pipes render them longitudinally resilient to compensate for irregular motion of the annulus 1. The admission of compressed gas is further controlled by a valve in the supply pipe 40, which is initially closed through a lever 61 and a link 60 by tappets 68 carried by the annulus 1 and is allowed to open suddenly under the action of a spring 58 to admit a sudden blast which applies a jerk to the filtering-medium. This action occurs when the tappets are withdrawn from the levers 61 by suction in cylinders 64, and the degree of suction acting to withdraw the tappets is adjusted by a needle valve.

Title: Improvements in emergency or stop gear for prime movers
IPC: F01D21/14
Filed: 1930-04-30
Abstract: 356,695. Engine stop-gear. SIEMENSSCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. April 30, 1930, No. 13376. Convention date, May 18, 1929. [Class 122 (iv).] A gear for a prime mover comprises a relay which functions when an error occurs in the driven machine and causes an alteration in the working magnitude of the driven machine supervised by safety devices, e.g. in the pressure of the lubricating-oil whereby the stop gear is brought into action. The speed through lever mechanism, the bearing temperature, or the condenser vacuum may be the operative factor. In the construction shown, when a fault occurs in an electric machine driven by a prime mover, a solenoid is excited and actuates the control valve of an oil-pressure relay to throttle or cut-off the fluid-supply to the primemover. Compressed oil pumped to the bearings of a turbine is supplied to a pipe 6 connected to the lower end of a cylinder and acts upon a piston 9 to hold the main shut-off valve 8 open against spring pressure 13. The solenoid 2 actuates an auxiliary valve 3 which allows oil to escape. The spring 13 closes the valve 8 upon a fall of pressure.

Abstract: 389,674. Refrigerating. HOOVER, Ltd., Perivale, Greenford, Middlesex.- (Assignees of Nelson, R. S. ; 1020, Cross by Street, Rockford, Illinois, U.S.A.) May 11, 1932, No. 13516. Convention date, May 23, 1931. [Class 29.] Absorption machines and systems.-Absorption of the refrigerant vapour is effected in two or three stages at progressively decreasing temperatures, the whole of the absorption liquid being passed through each stage. In a continuously-acting system operating with a pressure-equalizing inert gas, the mixed vapour and inert gas flow from the evaporator E through the duct 37 to the tubular heatexchanger 33 and thence through pipe 45, heatexchanger 50 and pipe 52 to the main absorber 22 from which the unabsorbed vapour and the inert gas pass through the pipe 53 to the second absorber 23 and thence through the pipe 54 to the third absorber 21. The inert gas returns to the evaporator through pipe 47, heat-exchanger 33 and duct 38. The hot weak liquor is carried by the vapour evolved in the electrically-heated generator 10 up the pipe 15 to the separator 29 from which the liquor flows through the heat-exchangers 50, 17 and the air-cooled coils 19 to the absorber 21 from which its flows in turn through the absorbers 22, 23 to the reservoir 28 and thence through the heat-exchanger 17 to the generator, while the vapour passes through the rectifier 30 and the water-cooled condenser c to a trap 32 from which the condensate passes through a pipe 35 to the top of the evaporator. The vapour separated in the trap flows through a pipe 34 to an injector 56 which promotes the flow of the mixed vapour and inert gas to the absorber 22. The absorber 22 is cooled by a volatile liquid which circulates through the absorber jacket 60, condenser coil 63 and air-cooled pipe 65. In a modification, the volatile liquid flows through pipes passing through the absorber 22 and connected to upper and lower headers which communicate with the condenser coil 63. The machine may be mounted in a compartment at the side or rear of a refrigerator cabinet upon the top of which is supported a tank of water containing the condensers c, 63. Specification 382,867 is referred to.
