Title: Improvements in and relating to electric excess consumption meters of the induction type
IPC: G01R11/185
Filed: 1937-07-02
Abstract: 497,858. Compensating meters for temperature errors. BRITISH THOMSON-HOUSTON CO., Ltd. July 2, 1937, No. 18431. Convention date, July 2, 1936. [Class 37] An induction meter, wherein the metering torque is opposed by a mechanical counter torque for measuring excess consumption, has an insert of alloy having a negative permeability-temperature coefficient in a magnetic path in shunt with the operative voltage or current flux for compensating the driving torque in the strengthening sense with increase of temperature, and means are also provided for simultaneously compensating the braking moment of the brake magnet in the strengthening sense to prevent over-compensation in the driving torque. The flux produced by the voltage coil V has a magnetic path 11, including an alloy insertion 4 having a negative permeability-temperature coefficient, in parallel with the air gap A to increase the flux passing across the gap with rise in temperature thereby compensating for the corresponding decrease in the meter torque and ensuring starting of the meter at the correct load. Alternatively, a magnetic shunt path 5 across the poles of the main current magnets C and also having a negative permeabilitytemperature coefficient may be used for compensating the driving torque. The brake magnet B is provided with a flux regulating magnetic element 6 having a positive permeability-temperature coefficient acting in known manner for temperature compensation. The mechanical counter torque on the disc 2 is produced by a pawl biassed by a spring 3 the tension of which is adjusted by turning a calibrated wheel indicating the starting load.

Patent GB-414210-A (GB)
Title: Improvements in or relating to the manufacture of oxygen generating or evolving substances
IPC: C01B13/02
Filed: 1933-08-02
Abstract: In the production of oxygen-evolving compositions by the reaction of an alkali superoxide with an alkali peroxide hydrate, the alkali superoxide, more especially after admixture with the alkali peroxide hydrate, is protected from the influence of the atmosphere by an inert fluid medium such as carbon tetrachloride or like non-combustible halogen substitution product of the paraffin series. The protecting medium may be liquid when added to the material, but may vaporize wholly or in part during the reaction.  The reaction product may contain known catalysts for accelerating the evolution of oxygen, or dehydratable water supply compounds, but preferably contains a catalyst capable of dehydration at temperatures of 140--200 DEG  C., for example the compound CuCl2.3CuO.3H2O.  Sodium or potassium peroxide may be employed as the alkali superoxide and sodium peroxide octo-hydrate as the alkali peroxide hydrate.  A plastifying medium such as clay or an inactive resin may be added to assist granulating during the manufacturing process.  The alkali peroxide hydrate may be formed by interaction of alkali peroxide and water prior to the introduction of the protecting medium, the grinding of the alkali superoxide and the admixing of the ingredients being subsequently effected in the same apparatus in the presence of sufficient liquid protecting medium to enable the latter operation to be conducted under wet grinding conditions.  The mixture of alkali superoxide and alkali peroxide may be consolidated by pressure before the reaction between them as started or reached completion, for example in a tabletting or like pressure-moulding machine. Alternatively, the mixture may be granulated, the amount of liquid medium being sufficient to make a paste.  The temperature during the process should be maintained between 80 and 120 DEG  C.  The alkali superoxide is preferably employed in a finely powdered form.

Abstract: 896,839. Electric selective signalling systems. GENERAL RADIO CO. May 30, 1960 [Feb. 19, 1960], No. 19115/60. Class 40 (1). [Also in Group XIX] Frequency -measuring apparatus comprises an electronic counter which counts pulses in successive predetermined periods of time and is reset after each counting period has an associated device adapted to store and display during each counting period the total reached by the counter in the immediately preceding period. The storage part of the associated device is of similar construction to the counter, and instead of acting as a store may be employed to increase the number of counting decades. The apparatus described may be employed as an eightstage decade counter or, by changing over switches S 1 , S 2 , Fig. 1, the four stages I only may be employed as a counter, the four stages II being employed as the storage part of a storage and display device. With the switches S 1 , S 2  changed over, input pulses supplied to a terminal 1 are counted for a predetermined period on the counter I. Counting is then terminated for a relatively short interval during which the total registered on the counter I is transferred over leads 3 to the store II, the counter I then being reset ready for the next counting period. Fig. 3 shows a bi-stable stage of one of the decades of the counter I connected over leads 3 to the corresponding bi-stable stage of the corresponding decade of the store II, the switch S 2  being changed over from the position shown. The bi-stable stages are double triodes 2, 2<SP>1</SP>, 102, 102<SP>1</SP>, but other components, e.g. transistors, may be employed. At the end of a predetermined counting period, a gate G is closed to terminate temporarily the supply of input pulses. The store stage 102, 102<SP>1</SP> is reset to make the tube 102 conductive by a pulse V<SP>1</SP> applied to a terminal 7, and a bias pulse V is applied at a terminal 5 to one side of a neon tube N. If the tube 2<SP>1</SP> is conducting, then by virtue of the connection of the anode of the tube 2 via a resistor R to the neon N, the neon N fires to cause the tube 102 to cease conducting and the tube 102<SP>1</SP> to conduct. If the tube 2 is conducting, the neon N is not fired and the tube 102 remains conducting. Thus the bi-stable stage 102, 102<SP>1</SP> takes up the samo state as the bi-stable stage 2, 2<SP>1</SP>. The stage 2, 2<SP>1</SP> is now reset by a pulse applied to a terminal D. The stage 102, 102<SP>1</SP> is connected over lines marked DISPLAY to a gas-tube or other known indicating or recording device. In a modification, Fig. 4 (not shown), the necessity for resetting the store stage 102, 102<SP>1</SP> is obviated, two neon tubes being provided in the transfer lead circuits.
