Title: Windscreen and wiper assemblies
IPC: B60S1/38
Filed: 1954-03-16
Abstract: 773,199. Windscreen cleaners. BROWN, D. S. June 16, 1955 [March 16, 1954], No. 7574/54. Class 138(1) A windscreen and wiper assembly includes a rigid transparent screen, a wiper member formed as a generally cylindrical body which can rotate about its major axis and is movable relatively to the windscreen with a translatory movement such that its major axis remains parallel to the surface of the windscreen and means for imparting the translatory movement to the member and at the same time rotating it continuously about its major axis at a speed such that the peripheral speed at the suface of the windscreen differs from the speed which would result from mere rolling of the wiper member over the surface of the windscreen. In the embodiment shown in.Figs. 1 and 2 the cylindrical wiper member 1 is mounted on a shaft 2 rotatable in bearings 3 and 4 on a spring arm 5 oscillatable with the spindle of a wiper motor (not shown). The member 1 is formed with a three-start helical wiper blade system 6 on its surface, the blades being urged towards the windscreen 7 by the spring 5. A pinion 9 on the shaft 2 engages teeth of a curved rack 8 on a fixed quadrant member 27 whose centre is on the pivoted axis of the arm 5. As the member 1 is oscillated over the windscreen it will be rotated in a direction opposite to that which would result if the member were rolled over the windscreen. In another embodiment the wiper member is linearly reciprocated across the windscreen, by having pinions at each end engaging stationary straight racks at the sides or top and bottom of the windscreen. Each end of the wiper member shaft is also provided with a block engaging a rotatable screwed shaft. The direction of reciprocation of the wiper member may be reversed by reversing the direction of rotation of the screwed shafts or by providing each of the shafts with two opposite-handed threads, in known manner, and rotating the shafts in one direction only. Water or other cleaning liquid or an anti-freeze solution may be supplied to the windscreen by providing the shaft 2 with a hollow centre and the member 1 with a passage or passages terminating at its surface and communicating with the centre of the shaft 2.

Title: Improvements in and relating to control mechanism for variable-pitch propellers
IPC: B64C11/42
Filed: 1946-03-12
Abstract: 609,529. Fluid-pressure servomotors. KROLDRUP, A. March 12, 1946, No. 7635. Convention date, Nov. 24, 1945. [Class 135] [Also in Groups XXIV and XXXIII] A single pump supplies operating liquid to both the cylinder of a hydraulic mechanism for changing the pitch of a propeller and a hydraulic friction or other clutch interposed between the propeller shaft and a driving shaft therefor. A driving shaft 1 is keyed to one part 2a of a friction clutch of which the other part 2b is keyed to the propeller shaft 3, a toothed ring 12 on the clutch part 2b driving an oil pump (not shown). The pump feeds oil to a socket 10 from which it may be directed to one side or other of a piston 6, actuating the blade pitch-changing mechanism and operating in a cylinder 7 formed on the propeller shaft 3, under control of a hand wheel 18. This wheel rocks a lever 22 about its lower end 23 moving a slide valve 31 to put a central oil channel 34, open to the socket 10, into communication with one or other of side channels 35, 36 which connect through passages 8, 9 with opposite sides of the piston 6. Rigid with the piston 6 is a sleeve 26 engaged by a fork 24 pivoted at 25 and again pivoted at its outer end to the lower end 23 of the lever 22. Movement of the sleeve 26 rocks the fork, displacing the lower end 23 of the lever 22 and returning the slide valve 31 to its neutral position. When the slide valve 31 moves, a valve 37, held open by its stem engaging in a central groove in the slide valve, is lifted to the closing position and cuts off a pressure gauge (not shown) which remains inoperative until the slide valve, by returning to its neutral position, indicates that the pitch-changing operation is complete.

Title: Method of and arrangement for evaporation of liquids with the recovery of the vapours by condensation
IPC: B01D3/00
Filed: 1920-03-16
Abstract: 164,525. Merz, F. March 16, 1920. Vapours, utilizing for effecting further evaporation.-A plant for evaporating, concentrating, or distilling liquids or for drying materials, comprising an evaporator or drying-chamber and a condenser for the vapours generated, is combined with a heat-transferring system of the type used for refrigeration, whereby the latent heat given out by the condensation of the vapours is transferred to the material in the drier or evaporator. The heat-transferring system consists of a closed circuit containing a volatile medium such as carbonic acid, ammonia, sulphurous acid, methyl chloride, or ether, which is vaporized by the heat given up in the condenser. The resulting vapours are compressed and liquefied under pressure, the heat given up being transferred to the material undergoing evaporation or drying. One form of apparatus consists of a drying-chamber 29 and a condenser 28 connected by a conduit 30, together with a heat-transferring system consisting of a vaporizing-chamber 25, a compressor 11, a liquefying-chamber 26, and a conduit 12 leading the liquefied medium back to the chamber 25. Pipes 21, 22 enable the air initially present to be removed through a pipe 23 leading to a pump, and a pipe 24 serves for the introduction of the volatile medium. Reduced and increased pressures may be maintained in the drier 29 and the condenser 28 respectively by means of a fan 4 in the conduit 30. In apparatus for evaporating liquids, the evaporator and condenser comprise heat-exchangers consisting of vertical tubes between headers, and the liquid under treatment and the volatile medium are caused tp flow in thin films over one surface of the tubes in the evaporator and condenser respectively. The liquid under treatment is returned from the base of the evaporator for further concentration. A heating-jacket furnishes a supplementary supply of heat. The evaporating-plant and the heat-transferring system may be separated, the heat being transmitted from the condenser to the liquid medium, and from the vaporous medium to the evaporator, by the circulation of another fluid.

Title: A Process for the Manufacture and Production of Aluminium-Chloride and Aluminium-Sodium Chloride.
Inventor: DUTT ERIC EDWARD
IPC: C01F7/58
Filed: 1918-05-10
Abstract: 123,243. Dutt, E. E., and Dutt, P. C. May 10, 1918. Aluminium chloride; sodium - aluminium chloride; sodium aluminate; potassium aluminate; arsenic trichloride.-Calcined clay and sodium or potassium chloride are heated in a rotary furnace to bright redness and vapours of arsenious oxide are passed over, to form sodium or potassium aluminate, silica, and vapours of arsenic trichloride. The aluminate is separated by solution in water, and carbon dioxide is passed through the solution, forming sodium or potassium carbonate and precipitating alumina. The alumina is mixed with coke and in some cases sodium chloride, and formed into briquettes, which are heated and treated with gases containing chlorine formed from the arsenic trichloride. Aluminium chloride or the double salt sodium-aluminium chloride is formed and distilled. The flue gases containing vapours of arsenic trichloride formed in the first operation are treated with steam to form arsenious oxide which is condensed by cooling and hydrochloric acid gas which is oxidized to yield chlorine by admixture with air and passage over heated catalytic surfaces such as small balls of clay impregnated with copper chloride. The gases containing chlorine are washed with water to remove hydrochloric acid and are dried. Specifications 4030/83 and 10011/86 are referred to.

Title: Absorption refrigerating systems
Inventor: HOPKINS NEIL EMERSON
IPC: F25B15/06
Filed: 1964-02-25
Abstract: 1,046,076. Refrigerating. BORG-WARNER CORPORATION. Feb. 25, 1964, No. 7861/64. Heading F4H. In an absorption refrigeration system a line 48 leading directly to the absorber 21 communicates with the strong solution line 23 at a point above the normal solution level 24 therein so that should crystallization occur in the liquid heat exchanger 22 solution will back up in line 23 and eventually flow through line 48. The hot solution thus forwarded to the absorber will mix with weak solution and be passed therewith through the tube side of exchanger 22 by pump 33, tending to melt the crystals. Relatively small capacity lines 50, 52 communicate with line 23 intermediate level 24 and line 48 so that prior to solution entering line 48 solution will flow first through line 50, then through both lines, to the absorber, temperature responsive means 59 being provided to actuate a throttling valve 41 in the generator steam supply on occurrence of such flow. The concentration of the solution leaving the generator will consequently be reduced, thus tending to melt the crystals. Should the solution level continue to rise flow through line 48 commences and temperature responsive means 54 acts either to reduce the supply of coolant to the condenser 14 by actuating a coolant by-pass valve 38 or to reduce the steam supply to the generator still further by actuation of valve 41. If these measures are insufficient to prevent flow through line 48 a timer T is operative after a predetermined period of flow to close a valve 70 in the absorber coolant circuit. Alternatively the timer may initiate a flow of steam through heating tubes in heat exchanger 22. Lines 48 and 50 are provided with U-bends 49, 51, the bends being filled with liquid from bleed tubes 61, 62 communicating with the discharge of pump 33, to prevent vapour communication between line 23 and the absorber.
