Title: Improvements in or relating to air pressure braking systems
Inventor: BALLARD DONALD HENRY
IPC: B60T13/565
Filed: 1958-10-16
Abstract: 904,737. Fluid-pressure brakes. CLAYTON DEWANDRE CO. Ltd. Jan. 18, 1960 [Oct. 16, 1958], No. 33073/58. Class 103 (1). A braking mechanism has a servomotor 4 disposed coaxially of and within a compressed air reservoir 1, means at one end of reservoir 1 by which manual input is transmitted mechanically to motor 4 and means extending coaxielly through the motor/ reservoir assembly for transmitting the output of the motor and the manuallyapplied effort to an hydraulic master cylinder 5 located externally of the reservoir at the other end thereof. The tandem-type master cylinder 5, the motor 4 and the end wall 3 of reservoir 1 are formed integrally, the motor 4 carrying a tubular housing 19 containing a hollow plunger 23 including a valve seat 25 normally engaged by a spring-pressed valve 27. The servo piston 31 has a stem 35 engaging the master-cylinder piston 11 and carries a control member 39 held spaced from valve 27 by a spring 40. In the release position, as shown, both sides of piston 31 are vented to atmosphere via ports 38, 41, and hollow member 39. On braking, plunger 23 is moved to engage valve 27 with member 39 and then move seat 25 from valve 27 to connect pressure reservoir 1 to the front side of piston 31 via ports 30, 28 and past seat 25, piston 31 then moving piston 11 and hence piston 12 to apply two sets of brakes via ports 9, 10. When movement of plunger 23 ceases the piston 31 and member 39 move to lap position wherein valve 27 engages seat 25 and member 39. The pressure in front of piston 31 acts via port 32 and chamber 33 on land 34 of plunger 23 to transmit " feel " to the brake pedal. When the applying force on plunger 23 is removed, spring 40 moves plunger 23 and disc 27 from member 39 to vent the servomotor, a spring 37 returning piston 31 to its inoperative position. Should the compressed air supply fail, then continued movement of plunger 23 moves pistons 31 and 11 mechanically.

Articles such as gloves are inserted in a carton or envelope by a pair of parallel plates, the plates being movable out of the parallel position when withdrawn, to enable an article to be placed between them. In a machine for filling cartons, carton holders 22 on a conveyer chain 14 are each brought opposite a sliding plate 34, operating in guides 36, which feeds a collapsed tubular carton from a stack in a shoot 32 and sets it up in a holder. The plates 52, 53 are each mounted respectively on carriages 55, 57 reciprocating at right angles to the conveyer path, the carriage 57 being mounted to run on the carriage 55 and carrying a rod 58 on which the plate 53 (shown in Fig. 1 in the vertical plane) is pivoted for movement about one longitudinal edge from the horizontal to the vertical plane. The article is placed on the plate 52 and the carriages 55, 57 and plates move forward together, the plate 53 pivoting into the horizontal plane. Both plates enter the carton and the upper one 53 is then withdrawn followed by the plate 52. During filling, a finger 47 previously advanced to fold over a carton end wall tab, remains in position to locate the carton endwise. After filling a similar finger 49 folds in the opposite end tab to hold the contents in position. As the carriages withdraw, cam means 68 causes pivoting of the plate 53 to its vertical position. The carton flaps may be finally closed by means as described in Specification 766,475. If envelopes are being filled, suction means may be employed to open them prior to entry of the plates.

Abstract: 1524458 Toy aeroplane, ship, &c., drives MABUCHI MOTOR CO Ltd 17 Aug 1976 [28 Aug 1975] 34165/76 Heading A6S [Also in Division H1] A radio controlled, battery operated toy aeroplane, ship, &c. powered by an electric motor 2 has cadmium-nickel, &c. batteries 1 supplying both the motor and its radio control receiver 3, the latter actuating a servo effecting steering, &c., and has a voltage responsive circuit breaker 8 to open a circuit between the battery and the motor when the voltage of the battery falls below a determined level, the coil 12 of the circuit breaker being connected across the battery 1. Additionally, a constant voltage regulator A and noize filter 10 are provided between the battery 1 and the radio control receiver 3. In the form shown, when the circuit breaker 8 trips and opens the contacts 13, 21, Fig. 4, the battery 1 supplies reduced current through a current-limiting rheostat 9 to the motor 2, but in another form the rheostat 9 is omitted. Reducing or cutting off the supply of current to the motor 2 conserves the residual power of the batteries 1 which is then still available to maintain control of the steering, &c. by operation of the radio control receiver 3, and also prevents reverse charging of the batteries. The noize filter consists of diodes D1, D2 and a capacitor C1 that suppress minor instantaneous variations, both positive and negative, of voltage in the supply to the radio control receiver 3. The constant voltage regulator A includes a transistor Tr2 for detecting fluctuations in potential, and a controlling transistor Tr1. The circuit breaker, Fig. 3, with its contacts 13, 21 and coil 12, comprizes a movable terminal 21 on a resilient metal plate 19 fast with an iron plate 18 and fulcrummed about a notch 26a in a frame 26. On depressing a push-button 23, the plate is engaged with and held against the core 14 of the coil until the voltage of the battery falls, when the resilience of the plate 19 disengages the contacts 13, 21 to break the circuit to the motor. The voltage of the battery necessary to maintain the contacts 13, 21 closed is adjusted by a screw 22 varying the mechanical stress in the resilient plate 19. A second press button 24 can be depressed to overcome the magnetic attraction of the plate 18 to the coil 12 and open the contacts 13, 21.

Patent GB-346657-A (GB)
Abstract: 346,657. Totalizators. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and JOHNSTON, A. J., 45, Primos Avenue, Folcroft, Pennsylvania, U.S.A. Dec. 11, 1929, No. 38032. [Class 106 (i).] In a totalizator counter employing pairs of impulsed switches for independently receiving and counting the impulses of one denomination have their bank contacts interconnected complementally to ensure correct transfer despite simultaneous receipt of two impulses. Single bank switches having ten stationary contacts are shown, though multiple bank switches may be employed. The switches 10, 11 are operated by stepping magnets 14, 15 energized in the known way. The stationary contacts are so connected that when the total number of impulses received by the two switches is equal to one less than a predetermined number, that is in the example shown equal to " nine," a pass-on impulse is transmitted to a totalizing device 16 having an actuating coil 17. The movable contacts of the switches are connected to the coil 17 while contacts 0 .. 9 of one switch are connected to contacts 9 .. 0 of the other switch each to each respectively. For example, if the switch 10 receives three impulses and then switch 11 receives six impulses, a circuit for the coil 17 is completed through contacts 3, 6 to operate the counter one step. The wipers of the switches 10, 11 each extend forwardly over two adjacent contacts to ensure energization of coil 17.
