Patent GB-115865-A (GB)
Title: Improved Manufacture of Plates for Electric Storage Batteries.
Inventor: WADE HAROLD
IPC: H01M4/20
Filed: 1917-04-04
Abstract: 115,865. Wade, H., (Flanders, L. H,). April 4, 1917. Electrodes.-Negative plates for storage batteries, while still wet from the pasting process, are subjected to the action of dilute sulphuric acid for from 12 to 48 hours. This may be done in a separate bath before reduction, or during the process of reduction, the plates being immersed in the acid while still wet and without previous drying. After reduction, the plates are dried in a non-oxidizing atmosphere. In one example, 420 lb. litharge are mixed with 16.8 litres of water, 3.57 litres of sulphuric acid of specific gravity 1.4 being then added in the form of a spray. The electrodes are then pasted with the mixture, each electrode, when pasted, being prevented from drying by being covered with a damp cloth. They are then immersed in sulphuric acid and reduced electrolytically to spongy lead. After washing with water, the electrodes are dried in steam at 250-300‹ F.

Title: Improvements relating to a coin operated pre-payment unit
Inventor: HORGAN WILLIAM FRANCIS
IPC: G07F15/12
Filed: 1956-02-16
Abstract: 797,152. Coin-freed apparatus. VENNER, Ltd. Feb. 18, 1957 [Feb. 16, 1956]. No 4911/56. Class 27 A prepayment unit for timed operation of a television set or other apparatus comprises a pair of contacts 24, 26 closed by insertion of a coin to initiate operation of a synchronous motor and of the television set and a cam 36 driven by the motor and holding the contacts closed for one revolution on insertion of a smaller coin and for two revolutions on insertion of a larger coin. Twin contacts 24 and a pivoted bridge contact 26 are mounted on jaws 20, 21 pivoted at 22 and the lower jaw has an extension 29 provided with a cam engaging pin 43 and a. pin 30 exteding through a slot 31 into a coin shoot 6. An inserted coin depresses the pin 30 slightly away from the end 32 of the slot 31 and causes the contacts to be closed so that the motor rotates the cam clockwise. The pin 43 then rides out of a depression 37 in the cam on to the circular periphery 36a and engages the tail 44 of one of a pair of "scissors" levers 7, 8 having pins 16, 17 which are swung into the coin shoot to prevent passage of any further coins. At the same time the pin 30 has moved down the slot 31 to the position 30a and if the coin is a sixpence, it can fall past the pin so that when the cam has completed one revolution the pin 43 can move into the depression 37 and cause the contacts 24, 26 to open. If the coin is a shilling, it is urged into engagement with the wall of the chute and the pin 30 by a catch 45 and, on completion of one :revolution of the cam, its presence prevents the pin 43 from entering the depression. However, the pin 43 rides over a release cam 41 at the mouth of the depression and, before falling back into engagement with the periphery 36a for another revolution, it moves the pin 30 to the end 33 of the slot 31 and thus releases' the shilling. When the pin 43 moves into the depression 37, it allows the pins 16 and 17 to move out of the coin shoot and any succeeding coins stored in the chute will maintain operation of the television set and of the motor. If the television set is separately switched off when the pin 43 is riding on the cam periphery and subsequently switched on, the motor will complete its revolution and use up the time paid for. A pivoted lever 51 at an inclined part of the shoot limits the number of coins that can be inserted at a time or, where the shoot extends vertically with an entry slot at its upper end, an unbalanced rotary disc with a cut-away for accepting coins may extend into the shoot, the disc rotating to pass coins until the last one maintains engagement with the cut away portion and holds the disc in a position masking the entry slot.

Abstract: 859,556. Ratchet clutches. MILLER & CO. Ltd., H. Feb. 18, 1957 [Feb. 17, 1956], No. 4961/56. Class 80 (2). In a one-way clutch having balls or rollers 16 jamming between cam recesses 15 in an input member 14 and a cylindrical surface in an output member 3, the rollers 16 are carried in apertures in a cage 17 subjected to the permanent brake torque of a fixed wire spring 24 which causes the rollers to jam in the cam recesses when the input member 14 is turned in the appropriate drive direction (clockwise, Fig. 2); and the cage apertures have resilient ears 18a which hold the rollers in contact with the cams. The input member 14 is driven through a chain 11 by the pedal shaft 2 of a motorassisted cycle, the output member 3 being one of two freely-mounted gear-wheels 3, 4 connected to the engine through a clutch, not shown, and connected to a road-wheel driving output shaft 5 through a two-speed selector clutch 6. Turning the pedal shaft 2 turns the engine through the one-way clutch 16 and wheel 3, the road wheel being also driven or not, depending on the engagement or otherwise of the selector clutch 6. When the engine starts, the one-way clutch 16 overruns.

Title: Improvements in or relating to liquid-level determining systems
IPC: G01F23/24
Filed: 1965-02-10
Abstract: 1,099,409. Liquid level indicators. SOCIETE INDUSTRIELLE DE LIAISONS ELECTRIQUES. Feb. 10, 1965 [Feb. 25, 1964], No. 5760/65. Heading G4H. [Also in Division G1] A semiconductor element 2, Fig. 1, having a very high inverse temperature coefficient of resistivity is used to determine the level of a liquefied gas by applying a fixed voltage to the element and measuring the current increase resulting from thermal runaway as the element crosses the liquid boundary. The normal current tends to heat the element, which may be carried in a stainless steel tube 10, and having reached an equilibrium value when the element is immersed in the liquid, the current increases by a large amount when the element passes into the vapour phase above the liquid, on account of the lower thermal conductivity of the vapour, which causes the current to heat the element to a higher temperature. This reduces the resistance further and causes the constant voltage source to supply an even larger current, the effect being cumulative until a new equilibrium is reached at a much higher current value. Several elements at different depths may be used to control a valve supplying liquid to a container, in order to stop the inflow when a desired depth is reached. The element may be made of silicon doped with boron, and a limiting resistor 6 may be included.
