Title: A new or improved valve or cock fitting particularly adapted for controlling the flow of water in connection with water softeners
IPC: C02F1/42
Filed: 1934-08-23
Abstract: 444,569. Valve fitting for watersofteners. MOUSLEY, N. K., 140, Granville Street, Birmingham. Aug. 23, 1934, No. 24283. [Class 135] [See also Group I] A valve fitting for controlling the directions of flow in a watersoftener for the operations of softening, regeneration, backflushing, and draining, comprises three valves 15, 16 and 17 controlling communication by way of internal passages in the valve body between connections 1, 2, 3, 4 and 5 to the hard water supply, the top of the softener, the bottom of the softener, the soft water supply, and the drain, respectively. In the normal operation of the softener the valves are in the closed positions as shown and the water passes from the connection 1, through the port 6 to the connection 2 and the top of the softener, from the bottom of the softener to the connection 3 and through the port 10 to the soft water supply connection 4, the passages 9, 13 and 23 being closed by the valves 15, 16 and 17 respectively. For back-flushing, the valves 15 and 17 are opened, the plunger 18 on valve 15 closing the port 6 and directing the water through passage 9 and port 11 to the bottom of the softener, the water entering from the top of the softener at 2 and passing to the drain through passage 7 and valve 17. To drain the softener prior to regeneration, the valve 16 is also opened, the plunger 20 closing the port 11 and shutting off the hard water from the passage 9, whilst the softener drains from the bottom through connection 3, valve 16 and passage 13 to the drain. The valves 15 and 17 are then closed for the regeneration and washing out so that the direction of flow through the softener is normal whilst the salt cap for the regeneration is replaced, the draining continuing through the valve 16. The valve 16 is then closed again for the normal operation of the softener to be resumed. Adjustable flow regulators may be incorporated in the fitting, for example the plug 24 controlling the rate of flow into the passage 9 when the valve 15 is opened. Modifications are described in which two valves only are used, the valves carrying one or more plungers or rings, such as 18 and 20, controlling ports for directing the flow through the passages in the valve body to effect the various operations as above.

IPC: H01Q1/18
Filed: 1953-09-02
Abstract: 766,344. Automatic control systems. SAVAGE & PARSONS, Ltd. Aug. 30, 1954 [Sept. 2, 1953], No.. 24309/53. Class 38 (4). [Also in Groups XXIV, XXXVI and XL (c)] A system in which a member is moved about two axes lying in planes perpendicular to each other is stabilized at a normal position by servomotors fed with error signals derived from controlling signals and from position signals giving a continuous indication of the displacement of the system from the normal position. The embodiment described is an airborne radar scanner stabilized against the effects of pitch and comprises a reflector 1, Fig. 1, rotatable in azimuth and elevation about shafts 8 and 9 through a differential gear (see Group XXIV), fed over two shafts 4 from two variable speed reversible motors 2 and reduction gears 3. The whole is supported on box frame 31 and cantilever 5, Figs. 1 and 3. Shafts 43 and 9 which carry the wipers of combined potentiometers and tachometers 41 and 42 (see Group XXXVI), the latter shaft through gimbal mounting 46, 47, 49 and which are aligned accurately at right-angles, are maintained respectively at true vertical within the pitch plane and at right-angles to it by the motor 40. The tachometers serve to produce damping and reduce hunting. The motor 40 is energized by a gyro-stabilizer and signals from potentiometer 45, the wiper arm of which is attached to shaft 43, to drive gear-ring 38, which supports this shaft, about ring 36, Fig. 3. Signals are produced in this way by potentiometers 41, 42 corresponding to deviations of the system from true azimuth and horizontal and are fed with the scan pattern controlling signals 28, 29 to opposite diagonals of a bridge network 50, Fig. 5, comprising eight equal resistors, to derive error signals which are fed through amplifiers 27 to control servomotors 2 and maintain the system in its normal position. The effects of roll may be obviated by means of motor 34 driving gear-ring 35 which supports cantilever 5 and motors 2. Tachometer 52 provides velocity damping. It is stated that the invention may also be applied to the stabilization of guns in tanks and ships. Specification 705,328, [Group XXIV], is referred to.

Title: Improvements in or relating to pneumatically-effected delayedaction tripping devices
IPC: F42C7/06
Filed: 1961-07-06
Abstract: 948,276. Switches held set and freed mechanically. REDON TRUST. July 6, 1961 [July 26, 1960], No. 24447/61. Heading H2B. [Also in Divisions F2 and F3] A delayed-action device particularly intended for land mines or electrical switches comprises a casing 1 with movable cover 2, a plunger 6 and a member 5 having a striker pin or contact 5<SP>1</SP>. The member 5 is urged to rotate by a spring 8, but is locked by the plunger 6. According to the invention the device is operated by applying a large and sustained pressure on cover 2 whereupon member 5 is directly depressed and plunger 6 simultaneously depressed by increase in air pressure above it (see Fig. 5). Subsequent leakage of air between the spaces above and below the plunger 6 allows the plunger to rise under the action of a spring 7 to release member 5 (see Fig. 6). For sudden large pressures the member 5 and plunger 6 are depressed, but maintain their relative positions and return together to the initial position. Various embodiments are described wherein the plunger overlies a striker-pin or contactcarrying member, relative rotation or movement between them being normally prevented by co-operating teeth or locking balls. Also, the casing may be divided into two non- hermetically sealed chambers by a flexible diaphragm attached to the plunger.

Title: Television synchronising system
IPC: H04N5/46
Filed: 1953-09-04
Abstract: 738,922. Television. STANDARD TELEPHONES & CABLES, Ltd. Sept. 4, 1953 [Oct. 27, 1952], No. 24544/53. Class 40(3). Auxiliary synchronizing signals (e.g. colour " burst signals) following normal line synchronizing signals are separated from the composite television signal by means of a gate circuit which is periodically unblocked by a signal derived from the line synchronizing signal. Referring to Figs. 1, 3 and 4, a conventional separator circuit 4 supplies line synchronizing pulses 21 to a circuit 5 comprising a damped resonant circuit 9, 11, 12 which, in response to the applied line pulses, generates a damped periodic wave 23 (Fig. 3, B) the positively-going part 26 of which coincides in time with the occurrence of the auxiliary synchronizing signal, in this case the colour " burst " synchronizing signal 22. The wave 23 is then employed as a gating signal to unblock a gate circuit 6 comprising a valve 15 which is caused to conduct by and for the duration of the tip of the part 26 and so pass only the signals 22 from the composite waveforms supplied from video amplifier 2. The separated " burst " signals 22 are employed in conventional manner to synchronize the colour oscillator 7. To prevent spurious gating (e.g. due to noise signals shock-exciting circuit 9, 11, 12) the gate circuit is arranged to be unblocked only during the simultaneous occur rence of the wave 23 and of pulses 24 (Fig. 3, C) derived from the line scanning circuit during the retrace intervals and supplied to the gate circuit (Figs. 2 and 5, not shown).

Filed: 1956-08-15
Abstract: 801,797. Refrigerating. PRESSED STEEL CO., Ltd. Aug. 15, 1956, No. 24926/56. Class 29 The invention relates to a compression refrigeration system including a liquid receiver between the evaporator and condenser in which the evaporator is defrosted by reversing the flow of refrigerant, and provides that refrigerant flows through the condenser 302 in the same direction during both normal operation and defrosting, the liquid receiver acting as a disengagement vessel during defrosting. This is effected by adding a line 315 between the evaporator 305 and condenser 302 and a line 314 between the liquid receiver 303 and the compressor 301, both used only during defrosting. In the preferred form the refrigerant circuit includes a reversing slide valve 340 and the pipe 315 is placed in heat exchange with the evaporator drip tray 351 and drain 352, being connected to the condenser inlet through a non-return valve 316, preferably a high-side float valve, and an expansion valve or device 319. Normal refrigerant flow is from the compressor 301 through lines 306, 309 to the condenser 302 and a liquid receiver vessel 303 from where liquid refrigerant passes to the evaporator 305 through the thermostatically controlled expansion valve 304, the evaporated refrigerant flowing to the compresser through suction lines 310, 311. On defrosting the slide valve 340 is operated and the refrigerant flows through evaporator 305, line 315, non- return valve 316 and expansion device 319 to the condenser 302, now acting as an evaporator, from where it passes to the receiver 303, vapour flowing through line 314 to the compresser. The non-return valve may be functionally integral with the reversing valve.
