Title: A membrane controlled gas valve for use in pressure regulators
IPC: G05D16/06
Filed: 1954-11-04
Abstract: 763,134. Valves. KROMSCHRODER AKT-GES., G. Nov. 4, 1954 [Nov. 5, 1953], No. 31913/54. Class 135. In a membrane-operated gas pressure regulator the spherical or conical surface of the valve 14 seats on the inner margin of a thin flatresilient valve seating ring 21. The valve has a coaxial inlet 26 and venturi outlet 23, the outlet pressure at a cylindrical throat portion 231 of the venturi, of length equal to the stroke of the valve, acts via a valve stem passage 25 in a chamber 4<SP>1</SP> on a weight-loaded diaphragm 3 so that outlet pressure is maintained with increased outflow. When the outlet pressure increases the valve seats on and deforms the seat 21, the wiping action produced keeping the valve and seat free from dirt. The valve rocks on a ball 13 and is secured to the stem by a diaphragm 15. Should the inlet pressure fail the valve closes on a seat 22 and is opened by inlet pressure acting on a sealing diaphragm 7. During regulation the diaphragm 7 compensates variations of inlet pressure acting on the valve.

Title: Improvements in or relating to cathode ray oscillographs
IPC: G01R13/22
Filed: 1934-11-07
Abstract: 440,058. Oscillographs. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, DONALDSON, D. H., c/o General Electric Co., Ltd., Wembley, Middlesex, and SMART, N. C., c/o General Electric Co., Ltd., Stoke, Coventry. Nov. 7, 1934, No. 32009. [Class 37] A cathode-ray oscillograph for determining the relation between two magnitudes both varying periodically with the time comprises a train of relays, operating in a self-maintained cycle, adapted to apply to the pairs of plates of the oscillograph, or their equivalents such as pairs of coils, in a regular cyclic order, two potential differences or their equivalents, each uniquely determined by one of the two magnitudes, and also two or more adjustable calibrat-. ing potential differences or their equivalents. When the relation of the two magnitudes to the time, as well as to each other, is required, the train of relays is also adapted' to apply a time base to one of the pairs of plates, as part of the cyclic order. An arrangement for measuring the relation between the potential across a rectifier, the current through it, and the time is shown in Fig. 2. The cathode-ray tube has two pairs of plates X, Y, one plate of each pair being earthed, and the various potentials are applied to the other plate of each pair by the operation and release of a relay having a single pair of contacts A1 and a second relay with three pairs of contacts B1-B3. The rectifier 1 is fed from a supply 2, 3 through a load 17, and is shunted by a reversed rectifier 4 through a resistance 18 to absorb the potential developed during the reverse phase. One of the contacts B1 is connected to the time-base generator, and one of each of the remaining pairs of contacts B2, B3 is supplied with potential developed respectively across a resistance S1 in series with the rectifier 1 and across the rectifier itself. The remaining contacts of each of the pairs B1-B3 are supplied with calibrating potentials from potentiometers 9, 12 and 14. The movable contact co-operating with the contacts B3 is connected to one of the fixed contacts A1 through an amplifier 16, the other fixed contact A 1 being connected to the movable contact co-operating with the contacts B2. In a simplified arrangement, Fig. 3, for measuring the relation between the grid voltage and anode current of a triode 1, the two fixed contacts A1 are connected together, and the contacts B3 are disconnected, the remaining pairs of contacts B1, B2 being supplied with potentials proportional to the grid voltage and anode current and with calibrating potentials from a potentiometer 8.

Title: Improvements in the hydrolysis of oils and fats
IPC: C11C1/04
Filed: 1946-10-30
Abstract: <PICT:0625139/III/1> In a process and apparatus for hydrolysing oils and fats at elevated temperature and pressure the water for the hydrolysis reaction is heated indirectly by a separately-generated hot fluid which is forced beneath the charge of oil in an autoclave by steam pressure generated by such heating.  Economy of plant, heat efficiency, and rapid charging of the autoclave are thereby secured. In the arrangement shown in Fig. 1, a low-pressure high-temperature fluid such as a mixture of diphenyl and diphenyloxide is heated in a low-capacity boiler 1 and passed through a coil 4 to heat water in a thermal storage tank or water accumulator 5.  At the same time, a batch of oil in an autoclave 6 is undergoing hydrolysis.  As soon as the hydrolysis is completed, the hydrolysed mixture is run out and a fresh charge of oil pumped into the autoclave by a pump 12. High-pressure steam and water at about 230 DEG  C. are then admitted from the accumulator 5 through cocks 10 and 8 respectively, and a fresh hydrolysis started.  The cock 10 is thereupon adjusted so that only so much steam is supplied from the accumulator 5 as is necessary for making up the heat lost by radiation and like losses.  At the same time the pump 11 is set in operation to pump a fresh charge of water slowly into the accumulator 5.  In an alternative arrangement, the charge in the autoclave 6 may be heated by low-pressure high-temperature heat transfer fluid from the boiler 1 passing through a pipe 14 and coil 13.  In this case a somewhat greater quantity of water needs to be admitted from the accumulator 5 at the commencement of the hydrolysis.  In another arrangement, applicable in the case when a supply of high-pressure steam is available, the boiler 1 is dispensed with and the water in the accumulator is heated by a coil through which such high-pressure steam is passed.

Abstract: 464,932. Thermal switches. WHITEHEAD, G. E., and WHITEHEAD'S ELECTRICAL INVENTIONS, Ltd. Nov. 21, 1935, No. 32345. [Class 38 (v)] A thermal cut-out or switch comprises 'a casing 1 containing mercury 10 held in place by wax 9 till excess current through the mercury heats the mercury melts the wax and allows the mercury to fall thereby breaking a circuit. The mercury in its fall may also complete another circuit or bridge contacts which may be subsequently brought into the original circuit by rotating the container. In the form shown in Fig. 1, the device, which is adapted to replace an ordinary cartridge fuse, comprises an insulating casing 1 with two end terminal caps 4 connected by pins 5 to internal contacts 3 and a central terminal 8 connected by a pin 7 to an internal contact tube 6. The circuit is normally between centre terminal 8 and top terminal 4 and current traverses the mercury 10 and if excessive heats the latter causing the wax 9 to melt. The mercury then drops breaking the circuit but bridging the contact 6 and lower contact 3. The wax now solidifies and if the device is inverted, it can clearly again be made to function as an overload fuse. In a modification, Fig. 2, the casing is drum-shaped and carries three contacts 13 connected to external terminals 15, 15, 15a. The terminal 15a is connected by a conductor 16 to trunnions through which current is conducted and in the position shown, the contacts 15 are engaged by contacts 19, 21, and mercury 22 bridges two of the contacts 13 completing a circuit 16, 19. On overload, the mercury warms up and melts the wax 12 which fills up the remainder of the interior of the drum. The mercury drops breaking the above circuit and completing a circuit 16, 21. The wax now solidifies, and the device may be brought into its original condition by rotating the drum through 120‹ by means of a handle 20. In another modification Fig. 4, (not shown), mercury fills up one-third of the interior.
