Title: Improvements in or relating to detachable electrical indicating instruments
IPC: G01R11/04
Filed: 1938-02-17
Abstract: 494,808. Current and voltage measurements ; two-part couplings. WESTING- HOUSE ELECTRIC & MANUFACTURING CO. Feb. 17, 1938, No. 4923. Convention date, March 20, 1937. [Classes 37 and 38 (i)] A detachable indicating instrument such as an ammeter, voltmeter, or wattmeter, is arranged so that the mounting of the meter on its support makes the proper circuit connections to the instrument movement. The casing comprises a base-plate 2, Fig. 2, and a transparent cover 4 clamped thereto by a sealing ring 6 and a gasket 8. Contact blades 10 project from the rear of the base for co-operation with fixed contact jaws by which the instrument is supported. Each blade 10 comprises a flat strip passing through a slot in the base and insulated therefrom by a member 12 on the interior of the base and a member 14 on the exterior formed with an upturned portion 16 to prevent the blade 10 from making contact with adjacent metal structures during insertion into the contact jaws. The inner portion of each blade 10 is provided with a screw 18 for making connections within the casing. An auxiliary base-plate 20, cut away to permit access to the screws 18, is supported on the inner face of the base 2 by spacing posts 22 and screws 23. The instrument shown is of the repulsion vane type having a winding 24 enclosing a chamber containing the fixed and moving vanes. The pointer 28 co-operates with a scale plate 32 which is spaced from the auxiliary base-plate 20, the auxiliary resistors, voltage multipliers, &c. required for calibrating the instrument being mounted on the plate 20 above the instrument movement and between the plates 20, 32. The side walls of the glass cover 4 are made translucent, as by painting or applying a coating 40. A number of different instruments may be adapted to engage a single set of contact jaws for making different measurements, for example, an ammeter winding 24, Fig. 3, is connected between an upper and a lower blade 10, the other two blades being short-circuited. Connections for a voltmeter are shown in Fig. 4, the winding 24 being connected in series with a resistance 44 as shown.

Title: Electronic Pulse Combining Apparatus
IPC: H03K21/02
Filed: 1967-02-01
Abstract: 1,179,571. Summing pulses. A. O. SMITH CORP. 1 Feb., 1967 [1 Feb., 1966], No. 4958/67. Heading G4D. An electronic pulse summating device combines pulses from a number of sources 1-4, each pulse setting a memory 16 which thereupon marks one input 23 of an AND gate 22. The other input 24 of each AND gate is sequentially marked through a corresponding gate 36 by a pulse generator 32 of appropriate frequency. Thus whenever a memory has been set the corresponding AND gate 22 responds, when scanned, to operate a monostable pulse generator 26 to pass a pulse of uniform duration through a summing circuit 14 and inverter to a recording counter 9. Simultaneously the pulse generator 26 signals back over lead 32 to reset the memory 16. The sources 1-4 may be flowmeters registering the flow of fuel from a tank. A pulse on lead 33 resets all memories 16.

Title: Improvements in or relating to control system
IPC: G05B1/04
Filed: 1947-02-20
Abstract: 628,643. Automatic temperature control systems. WHEELCO INSTRUMENTS CO. Feb. 20, 1947, No. 4982. Convention date, March 14, 1946. [Class 38 (iv)] The outputs of two oscillators 23 and 24 are varied, by means of reactance elements 21, 22, associated with a galvanometer pointer 17 having stepped portions 19, 20 and giving an indication of temperature or other condition to be controlled, and utilized to compensate for any deviation of the temperature or other condition. As shown, a furnace 10 is supplied with fuel through valves 11 and 12 controlled by solenoids 13 and 14. A thermocouple 15 is connected to the coil 16 of a galvanometer so that variations in temperature of the furnace produce a proportional change in the movement of the coil. The pointer 17 connected to the coil carries a stepped metal flag 19, 20 and inductance coils 21, 22 are mounted respectively adjacent the path of movement of the flag portions 19, 20. The coils 21 are connected to the input side of the oscillator 23, whilst coils 22 are connected to the oscillator 24, both oscillators being in tune and therefore, capable of causing relays 27 and 28 to be energized when the flag is displaced from the coils, but detuned when the flag is adjacent or between the coils. Oscillator 23 when detuned releases the relay 27 to de-energize the solenoid 13, and thereby close the fuel valve 11, while oscillator 24 similarly operates a fuel valve 12, through the relay 28 and the solenoid 14. In the -position shown, both valves are closed. As the temperature of the furnace falls the flag portion 19 moves away from between coils 21 opening valve 11. If the temperature continues to fall the pointer continues to move to the left until flag portion 20 is clear of coils 22, opening valve 12. As the temperature rises again the pointer then moves to the right, bringing flag portion 20 between coils 22 again and closing valve 12. The coils 21 and 22 are mounted on pointers 38 and 39 which may be adjusted separately or together, so as to increase or decrease the range, or to vary the normal temperature of operation.

Patent GB-608317-A (GB)
Title: Improvements in and relating to the combination of acoustic frequency signals from aplurality of sources
IPC: H03G3/24
Filed: 1946-02-19
Abstract: 608,317. Telephone transmission systems. BRITISH BROADCASTING CORPORATION, and HAINES, F. J. G. Feb. 19, 1946, No. 5221. [Class 40 (iv)] In a method of combining signals from a plurality of microphones, the amplitude of signals from a first microphone is limited over a predetermined range in accordance with the voltage developed by a second microphone. One microphone 10, Fig. 1, which may be receiving crowd noises or other effects, passes its output through a limiter 11, the maximum output of which, at terminals 14, is controlled by a voltage applied at terminals 16, and the final output passes through attenuator 12 to terminals 13. In the absence of any output from a speech microphone 17, which is directly connected to terminals 13, the amplitude at terminals 14 is kept below a predetermined level by a control circuit 15, but when speech signals are received, over terminals 18, a part is rectified in circuit 19 and passed to control circuit 15 to reduce the final output of microphone 10. The circuit 15 is so arranged that the signals from microphone 10 may not, however, fall below a predetermined value. The circuits of the units 15, 19 are shown in Fig. 2. Signals from terminals 14 are connected through an amplifying valve V1 to a full-wave rectifier arrangement 21 and thereby apply a bias to the grid of V2 in opposition to a standing bias produced by resistor 22. Whenever the level of these signals produces the predominating bias, current pulses flow in valve V3 and the output is rectified in diode V4 to bias back the limiting stage 11, Fig. 1, at terminals 16. Consequently the final output from this microphone can never rise above this predetermined level. Signals from the speech microphone are rectified in V5, Fig. 2, which works on the upper bend of its characteristic, and the rectified output is applied at points 20 so as to tend to neutralize the bias developed by resistor 22, and thus cause V2 to limit at a lower level. Since V5 is nearly saturated, the control voltage it can produce is limited and can be adjusted by variable resistor 26. The output from the effects microphone will not drop below the level set by this. Specifications 481,830 and 509,309, [Group XL], are referred to.
