Abstract: 742,419. Fluid-pressure engines; valve gear. TECALEMIT, Ltd. June 17, 1953 [Aug. 1, 1952], No. 16726/53. Class 122(2) A pressure-fluid operated motor comprises a main piston 1 and an auxiliary piston 2 successively reciprocated in cylinders 20 and 24 respectively having their axes at right angles and alternately supplied at either end, whilst the other end is open to exhaust, with pressure fluid distributed by a single slide valve 3 coupled to the piston 2 so as to reciprocate therewith and to a rod 17 having a lost motion connection with the piston 1 so that the valve is moved by that piston at each end of its stroke only. The ends of the cylinder 20 are formed by a block 43 through which the piston rod 14 extends and a member 23 bored longitudinally to house the slide valve 3 and transversely to form the cylinder 24. The slide valve is slidably held between collars 19 on rod 17 joined to a rod 16 having a head 18 slidable in a closed bore 15 in the piston rod 14. The complete motor is housed and secured in a bell-shaped casing 49 by a nut 52, toric sealing rings being provided between the cylinder covers 23, 43 and the casing. Pressure fluid is supplied via an inlet 31 and a filter 33 to the slide valve housing and in the position shown flows through port 9, conduit 9a, space 41 and apertures 9c to the top. of piston 1, whose underside is open to exhaust through passage 8c, space 8b, conduit 8a, port 8 and exhaust port 7, and which toward the end of its downward stroke moved the slide valve down to open to pressure a port 12 leading by conduit 12a to the right hand side of piston 2 and connect the left hand side to atmosphere via conduit 11a, port 11 and exhaust port 7. The piston 2 is thereby moved to the left carrying with it the slide valve which then connects the underside of piston 1 to pressure through port 8, while exhausting the top side by connecting ports 9 and 7; the piston 1 moves upward and toward the end of its stroke raises the slide valve to connect port 12 to exhaust port 7 and open port 11 to pressure and thereby cause piston 2 to move from left to right to its original position. Port 9 is then open to pressure again and port 8 is connected to exhaust port 7 so that piston 1 is moved downwards and towards the end of its stroke moves the slide valve back to its original position to allow a further cycle of operations to commence. In a modification, Fig. 3 (not shown), the rod 17 is extended above the slide valve 3 to sealingly engage in a bore open at its top end to the atmosphere and the pressure fluid inlet is arranged at the bottom of the casing 49.

Title: Production of water-soluble aromatic resin sulphonates
Inventor: BAUMAN WILLIAM C
IPC: C08F8/34
Filed: 1956-05-30
Abstract: Water-soluble resin sulphonates are obtained by reacting copolymers of vinyl toluene dispersed in liquid sulphur dioxide with at least 0.7 molecular equivalent of sulphur trioxide per molecular equivalent of vinyl toluene, at a temperature of not higher than 40 DEG  C.  The copolymers contain at least 60 per cent by weight of vinyl toluene chemically combined with an olefinic compound containing a carbonyl or carbonyloxy group in the molecule, e.g. maleic anhydride, dimethyl and diethyl maleates, methyl isopropenyl ketone, acrylic and methacrylic acids and methyl, ethyl, and propyl acrylates and methacrylates or mixtures thereof.  The reactants may be admixed before or during the reaction, which may be made continuous, at a pressure sufficient to maintain a dispersion of unreacted copolymer in liquid sulphur dioxide.  The product precipitates as small granules which may be separated and washed with liquid sulphur dioxide which is removed by vaporization.  Salts may be prepared by neutralizing with alkalis such as ammonia and sodium and potassium hydroxide, solutions of which may be used as sizing agents. Specification 746,616 is referred to.

Title: Method of producing highly emissive thermionic cathodes according to the metallic vapour process
IPC: H01J9/04
Filed: 1932-06-16
Abstract: 395,862. Thermionic cathodes. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, and WALDSCHMIDT, E., 30, Birkbuschstrasse, both in Steglitz, Berlin. June 16, 1932, No..16999. Convention date, June 20, 1931. [Class 39 (i).] Highly emissive cathodes are made by producing on a tungsten wire a coating of the higher oxides, WO3 and W2O5, reducing these oxides to tungsten dioxide, WO2, and vaporizing an alkaline earth metal, such as barium, on to the dioxide. The tungsten wire is initially cleaned by passing through a furnace 1, Fig. 1, at 400-500 C. to oxidize the surface and burn off organic matter and then passing through a molten alkaline mass 4, such as caustic soda at 300-400, to remove the oxide and impurities. Prior to passing through the mass 4, the wire may also be passed through a solution 2 of bichromate in concentrated sulphuric acid to make organic impurities, such as aromatic oils, soluble in water, the wire then passing through water baths 3, 5. Water is supplied continuously to the bath 3 and the slightly acid water from the bath 3 is passed to the bath 5. The cleaned wire is passed through a furnace at 700 C. to form the higher oxides and then through a reducing furnace 11, Fig. 2, to form the dioxide. A mixture of hydrogen . and steam enters the furnace 11 at 13 and is preheated in a chamber 15. Chemical action on the wire at intermediate temperatures is avoided by end cooling chambers 12 containing boiling water. Indirectly heated cathodes comprising a spiral tungsten wire around an insulator containing a filament are passed through the furnaces on conveyer bands, trap-doors being substituted for the narrow passages 14.

Abstract: 796,011. Fire alarms. PETCAR RESEARCH CORPORATION. June 11, 1954 [June 16, 1953], No. 17184/54. Class 118 (1). A circuit for detecting the presence of flame, for example in an aircraft engine nacelle, comprises a pair of closely-spaced conducting wires 2, 4 arranged in the space to be protected, one wire 2 being supplied from an alternating current source 8 through a filter 10 which suppresses at least one harmonic of the frequency generated by the source, and the other wire 4 being connected to an amplifier 20 which passes only signals of the frequency of the suppressed harmonic or harmonics, the output of the amplifier controlling an alarm device comprising a relay 28 and lamp 30. When a flame bridges the wires 2, 4, it acts as a non-linear impedance, whereby the suppressed harmonic is generated and the alarm operated. In order to prevent the operation of the alarm by noise or by rain an amplitude selector 22 and a counter circuit 24 are provided. The selector 22 comprises a thermionic-valve trigger circuit which is operated only by signals exceeding a predetermined amplitude. The counter circuit 24 comprises a further thermionic-valve circuit which only supplies an output large enough to actuate the relay control circuit 26 when the signal applied thereto is substantially continuous, whereby signals due to rain, which occur in short bursts, do not actuate the alarm. The signal from the filter 10 is applied to the wire 2 through a negative-feedback amplifier 12.

Abstract: 1378701 Dialysis apparatus RHONE-POULENC SA 13 April 1972 [13 April 1971] 17190/72 Heading B1X [Also in Division A5] A pressure modulator for an artificial bloodcircuit comprises a resilient wall 2b, Figures 3, forming part of a blood chamber 2c having an inlet duct (17) Figure 4 (not shown) and an outlet duct (18), a pair of rigid plates one on either side of said chamber and forming part of an exchanger 2, at least one pulsation chamber 2a disposed on the side of one of said plates remote from said chamber, and fluid pulse producing means 7, 8, 10, Figure 1, connected to the pulsation chamber or chambers to cause flexing of the wall 26 and thereby pulsing of liquid in the blood chamber. A pump 1 feeds blood to exchanger 2, which may be in the form of a dialyser or diaphragm oxygenator, via an arterial inlet 12 to an organ 3 and along a venous outlet 13 to an inlet of the pump. A pressure gauge 4 connected across the exchanger 2 controls the flow rate of the pump 1. The pulsation chambers 2a are connected by means of a duct 14 to a fluid source 5, preferably air, under pressure and to a source 6 at atmospheric pressure or under vacuum. A three-way electromagnetic valve 10, which is controlled by contact pressure gauges 7, 8, switches connection of sources 5, 6 and the pulsation chamber 2a. Variable fluid resistances 9, 11 are provided between respective sources 5, 6 and the valve 10. Adjustment of the fluid flow through resistances 9, 11, or modification of the volume of the pulsating chamber, produces a pressure modulating effect on the walls 2b of the exchanger which in turn affects the volume of blood in chamber 2c. A blood pressure waveform is produced which approximates closely to the systoles and diastoles of a heart. A modified form of exchanger, Fig. 4, utilises non-return valves (15), (16) arranged in the respective ducts (17), (18) thus excluding the use of the pump.
