Abstract: 761,812. Fluid-actuated valves. FAUST, D. G. May 17, 1954 [June 8, 1953], No. 14389/54. Class 135. A pilot-controlled pressure regulator has a reciprocably movable closure member 18 associated with a piston and cylinder assembly 28, 30 whereby the closure member is substantially balanced as regards outlet pressure and includes a series of coaxial chambers separated from one another flexible walls, such as the diaphragms 50, 54 operatively connected to the closure member 18, one of the chambers II being so connected to the valve outlet that fluid flowing through the outlet lowers the pressure in this chamber, an adjacent chamber III being open to the atmosphere, and a third chamber IV being connected with the valve inlet through a spring-controlled pilot pressure regulator and with the atmosphere through a spring-loaded relief valve. As shown, the closure member 18 is substantially balanced by an extension 28 sliding in a recess 30 containing a spring 34 and connected by passages 36, 38 with the outlet side of the closure member 18. The closure member 18 co-operates with a removable seat 20 and has an upper extension or plunger 44 sealed by a diaphragm 46 with respect to a baffle 22 separating two chambers I, II. The chambers are connected by a tube 21 projecting into the main outlet 16 so that flow through the outlet creates a reduced pressure in the chamber II. The chamber II is substantially closed by a diaphragm 50 separated from the baffle 22 by a spacer 52 and from the 'diaphragm 54 by a spacer 56 having passages 60 to vent the intermediate chamber III to atmosphere. The diaphragms 50, 54 are rigidly connected through their backing plates 51, 55 by a ported brace element 58. The chamber II is permanently connected to the chamber III by a bleed orifice 64 and when the pressure in the chamber II exceeds a predetermined value a ball valve 48 on the plunger 44 uncovers a passage 62. The pilot pressure regulator is connected to the main inlet 14 by passages 70, 72, 76, 78 and comprises a spring-closed ball valve 85 connected to a diaphragm 87 by a plunger 86 the upper end of which normally closes a relief opening 90 in a diaphragm insert 88 also having a bleed orifice 94 to connect the chamber IV to atmosphere through a passage 83. The outlet of the ball valve 85 is connected to the chamber IV through a passage 81. The diaphragm 87 is loaded by a spring 92 adjusted by a screw 94.

Abstract: 1,002,732. Evaporators ; distilling sea water. J. P. LYNAM. April 16, 1962, No. 14668/62 Heading B1B. In an apparatus, for distilling liquids such as sea water, comprising a primary evaporator 34 and a secondary evaporator 22, both evaporators being divided into a series of chambers each embodying a flash-section and a condenser-section, wherein an auxiliary flash chamber 33 is connected between the flashsection of the final chamber 16 of the primary evaporator and the first flash section of the secondary evaporator 22, the vapour which is flashed off in the auxiliary flash chamber 33 is passed to a compressor 28 and the compressed vapour is conveyed to a heater 27 where it is used to supply additional heat to the sea water (or other liquid) which has been passed through the condenser tubes 37 of the primary evaporator ; the hot sea water is then introduced through conduit 30 into the first flash section 1 of the primary evaporator. The sea water to be distilled is pumped into the system through conduit 17, and most of it is first passed through the condenser tubes 40 of the secondary evaporator. Some of the sea water is diverted through heat-exchanger 20, where it is heated by the warm condensate (i.e. distilled water) withdrawn from the trays 36 in the primary evaporator and from the heater 27. The two streams of sea water, which have left the tubes 40 and the heat-exchanger 20 respectively, are re-united in conduit 20 ; and the water is then pumped, together with some of the water withdrawn from auxiliary flash chamber 33, though the condenser tubes 37 of the primary evaporator. The remainder of the water withdrawn from chamber 33 flows to the secondary evaporator. The distilled water which has left heat-exchanger 20 is united with that withdrawn from the collecting-trays of the secondary evaporator, and the combined stream is pumped out of the apparatus. The compressor 28 is actuated by a steam turbine or I.C. engine 38. The waste heat of the prime mover is used to produce steam in boiler 35, and this steam may be used to heat the sea water in an auxiliary heater 25, which may be disposed in either of the two positions shown. If desired, some of the distilled water may be submitted to flash distillation in order to obtain doubledistilled water.

Abstract: 1,100,732. Magnetic compositions. SIEMENS A.G. 7 April, 1965 [8 April, 1964], No. 14674/65. Heading HIH. A method of manufacturing rectangular-loop ferromagnetic cobalt-containing ferrite cores, particularly cores of perminvar ferrites, i.e. ferrites which exhibit a constricted hysteresis loop prior to a magnetic annealing treatment which produces a rectangular loop, comprises sintering a mixture of metal oxides and subjecting the sintered ferrite cores to a rapid cooling treatment at a rate exceeding 25‹ C. per minute from the Curie temperature to a temperature less than 200‹ C. prior to the application of the magnetic annealing process which produces the rectangular loop. The invention is applicable to ferrites containing more than 50 mol. per cent Fe 2 O 3 . MnZn, NiZn, MnNiZn and MgZn ferrites are mentioned. In an example, cores were formed from a mixture comprising 58 mol. per cent Fe 2 O 3 , 30 mol. per cent NiO, 12 mol. per cent and 0.5% by weight CoO. These were pressed into shape, sintered at 1220‹ C. for 2 hours and slowly cooled to room temperature over 10 hours. They were then reheated to 500‹ C. and rapidly cooled at 40‹ C. per minute to below 200‹ C. The cores were then subjected to magnetic annealing at 280‹ C. under 3Oe. for times from 10 minutes to 64 hours. The rapid cooling may be effected immediately after sintering or, as described above, following an intermediate cooling and reheating stage.

Filed: 1939-05-17
Abstract: 529,394. Batteries. GORDON, C. J. May 17, 1939, No. 14716. [Class 53] In an air-depolarized cell having electrodes of gas carbon and magnesium, the carbon surface facing the negative electrode is treated by removing its skin so as to expose the pores, and forcing into the pores a carbon substance of higher conductivity than gas carbon. In the cell described, a number of parallel connected magnesium rods 1 is arranged around a perforated tube 10, of paper or cardboard, inside a carbon cylinder 3, the intervening spaces being filled with wood wool 2 and the lower part of the cell being closed by a waxed cardboard bottom 8. The magnesium rods are connected to a terminal 5 and a clamping ring 4 serves as terminal for the carbon electrode. Before assembly, the inner surface of the carbon is scraped to remove the hard face and to expose the pores. Acetylene soot or oil carbon is then sprinkled on the inner surface and pressure is applied by means of a roller until the whole surface is covered with the soot well worked into the pores. A few crystals of potassium bromide are placed at the bottom of the cell and when the cell is required for use water is added which is rendered conductive by the potassium bromide and is absorbed by the wood wool. in contact with the electrodes. During use of the cell the increased volume required by the production of magnesium dioxide is accommodated by the crushing of the central cardboard tube. The magnesium ,rods may be made of an alloy containing aluminium and manganese. Specifications 423,301, 423,353, 423,738, 437,821, 441,894, 443,983 are referred to.
