Abstract: 1,249,903. Encasing batteries. SOC. DES ACCUMULATEURS FIXES ET DE TRACTION. 30 Dec., 1968 [28 Dec., 1967], No. 61770/68. Heading H1B. A battery comprising a stack of superposed cells is enclosed in a tubular sheath of plastics material having an inner surface adapted to hold the constituent layers of each cell in place and to prevent leakage from one cell to another and a stretched second sheath of a resilient plastics material which exerts a radial and axial pressure on the first sheath and the stack therein as a result of its tendency to revert to its unstretched condition The second sheath may also be deplasticized to cause further shrinkage. The second sheath 11 is stretched by placing one end over the tapered end 9 of the vacuum cup 7 (Fig. 2) and holding it in place by locking ring 10. Application of vacuum at outlet 8 draws the tube which has been dipped in trichlorethylene into the cup and stretches it to conform to the inner wall thereof as shown at 11<SP>1</SP> The battery stack enclosed in the first sheath is then placed in the second sheath and the vacuum is released allowing tube 11 to contract on to the battery. After locking ring 10 has been removed the end of tube 11 is turned over the end of the battery. Evaporation of trichlorethylene causes the tube 11 to contract still more and to grip the battery firmly.

Abstract: 652,628. Counting-apparatus; totalizators. UNION TOTALISATOR CO., Ltd., and HANDLEY, J. Dec. 5, 1947, No. 32106. [Class 106 (i)] An aggregator in which escapement wheels 34, 35, 36, Fig. 2, are urged to rotate by light springs 37, 38, 39, when released from escapement levers, has a spring-loaded drive 42, Figs. 2 and 2a, which operates through summating differential gears, said drive being arrested by a fixed ratchet wheel 41, Fig. 3a, when the differential train has taken up the movement of the released escapement wheels. The invention is particularly applicable to totalizators as described in Specification 592,946. In the normal locked positions of the escapement wheels 34, 35, 36 the corresponding differential gear units 54, 49 are arrested by the abutment of pins 45 on the cases of the light coiled springs 37, 38, 39 with pins 46 on the escapement wheels 34, 35, 36. The sun wheel 50 of the second differential gear unit ismounted on a shaft 51 which carries an arm 43 connected by a spring 42 to a wheel 26 constantly urged to rotate but normally locked by the engagement of a pawl 40 carried thereby with a fixed ratchet wheel 41, Fig. 3a. The escapement wheels 34, 35, 36 are individually released, upon energization of their electromagnets (not shown), as bets are received and are stepped-on by their corresponding springs 37, 38, 39. The spring 42 thereupon pulls the arm 43 clockwise, Fig. 2a, and a roller 44 carried thereby lifts the pawl 40 away from the ratchet wheel 41 so that the gear 26 rotates until the pins 45, 46 again abut. The arm 43 stops and the pawl 40 over-runs the roller 44 and urged by a spring 47 again engages the ratchet wheel 41. The ratchet wheel 41 is located on a boss 58 which has a tongue 59, Fig. 3a, constantly urged by a C-spring 60 against a tongue 57 on the ratchet wheel 41. The spring 60 flexes to take up the shock produces when the pawl 40 engages the ratchet wheel 41 at high speed.
Patent GB-679560-A (GB)
Abstract: 679,560. Valve amplifying circuits. BENDIX AVIATION CORPORATION. Nov. 2, 1949 [April 28, 1949], No. 28104/49. Class 40 (vi). [Also in Group XXXV] A varying input is applied to a device to convert it into a signal with a predetermined time function, part, at least, of the signal being fed back into the input. The circuit may be employed to separate high and low modulationfrequencies on a carrier of supply frequency. A signal in the form of amplitude modulation of the supply frequency is fed over transformer 10 to an amplifying valve 14 which in turn feeds discriminator valves 22, 23 energized in opposite phase on their anodes. According to the relative phase of the signal and supply the current in one or other of the valves 22, 23 increases while the other decreases. The heat dissipated in coils 29, 30 varies so that the resistance of elements 34, 35 alters to upset the bridge formed with the tapped resistor 36. The resulting error current at supply frequency is fed back through transformer 45 to oppose the input to valve 14. The thermal delay device 33, of the type described in Specification 603,610, [Group XXXVI], causes the feed-back voltage to build up slowly. This voltage is fed out over transformer 42 and due to the heavy feed-back results in a substantially linear relation between input and output when a steady state is reached. The output from transformer 47 is the difference between the rates of change of the input and output signal and may be utilized in the servo control system. In a modification used in a servo control system (see Group XXXV) in an aircraft an error signal from a radio receiver, modulated on the supply as carrier is fed to transformer 61, Fig. 2. The output from secondary 63 feeds transformer 68 which in turn supplies an input to the amplifiers operating the servo mechanism controlling the rudder and aileron. The output from secondary 64 feeds an amplifier-discriminator of the type shown in Fig. 1 so that a feedback voltage is built up over transformer 145 to neutralize the input from secondary 64 fed to transformer 69. In a similar manner, as the input falls, the output on wire 70 due to transformer 68 falls immediately but due to the time constant of the delay device the feed-back voltage falls slowly, thus, in effect, damping the whole system. Specification 675,751 also is referred to.
Patent GB-769088-A (GB)
Abstract: 769,088. Fare boxes. GRANT, M. L. May 20, 1955, No. 14532/55. Class 106 (3). A fare box is adapted to receive both tickets and coins and has separate inspection areas for the coins and the tickets with means for separating the tickets and coins and for depositing them in their respective areas. The tickets and coins are inserted through a slot 17, Fig. 4, in a transparent fare hopper 12 and fall down a transversely convex slideway 18 on to a second slideway 27, Fig. 3, similarly convex, and thence on to a plate 24 provided with a nylon mat 29 on which tickets are retained, the coins rolling down to enter a narrow space 30 between the section 25 and the cover-plate 26 and via an inclined track 31 on to a track 32 to line up vertically on a rail 34 and rightangled track 36. The track 36 is supported on a lever 37 pivotally mounted at 39 and bearing at its other end a weight 41 so that on the accumulation of sufficient coins the lever 37 swings to drop the coins through passage 42 into the fare collection box. The cover-plate 26 adjacent the ticket-holding area 24 and the coin-holding area 30 is transparent to permit inspection. The section 24, 25 comprising the back supports of these inspection areas is pivoted at 64 and may be moved to the position shown in dotted lines in Fig. 4 by elevation or depression of a U-shaped bar 45 pivotally connected to a lever 52 having at its outer end a roller 61 bearing against a plate 62 secured to the section 24. A cam surface 59, 60, 60a on the pivot 47 co-operates with stops 56, 57 and the U-shaped bar may thereby be latched in the upper position. The pivotal movement of the section 24, 25 ejects the tickets and coins into the fare collection box. Means locking the cover 26 to the housing, and means locking the collection box in position may be provided, such locking means being rendered inaccessible unless the U-shaped bar 45 is in its upper position and therefore the inspection areas emptied of coins and tickets.
