Filed: 1929-11-15
Abstract: 343,462. Coin-freed apparatus. WITTENBORG, E., 31, Kongensgade Odense, Eyen, Denmark. Nov. 15, 1929, No. 35037. [Class 27.] Testing coins.- A tilting-device in the coin shoot of coin-freed apparatus which allows serrated coins to pass but which stops smooth coins, comprises three members, viz. an arm 5 pivoted at 6, a pawl 7 connected thereto, and a stop 11, the pawl being provided with a single tooth 8, an oblique edge 9, a nose 10 to co-operate with the stop 11, and a stop arm 12. A serrated coin engages the tooth 8 and rotates the pawl so that the nose 10 passes the stop 11 as the device is lifted, thereby allowing the coin to run down the shoot. A smooth coin does not rotate the pawl and the nose 10 engages the stop 11, thus preventing further movement of the device. The smooth coin becomes wedged against the oblique edge 9 and is retained until the shoot is opened in the usual manner.

Title: Improvements in and relating to brake actuators
IPC: F16D65/28
Filed: 1969-07-14
Abstract: 1,271,247. Brake actuators. ROBERT BOSCH G.m.b.H. 14 July, 1969 [13 July, 1968], No. 35307/69. Heading F2F. A compressed air brake actuator for a motor vehicle fitted with an anti-skid device comprises a first piston 9 one face of which forms a movable wall of a working chamber 32 connectible to a source of compressed air for the purpose of actuating a brake and an opposite face of which forms a movable wall of a second working chamber 30 adapted to have compressed air supplied thereto upon actuation of a wheel-lock sensing device of the anti-skid device for the purpose of releasing the brake, the chamber 30 being formed between the piston 9 and a second piston 16 which is arranged to follow movements of the first piston so as to maintain the volume of the chamber 30 constant when no compressed air is supplied to that chamber, during operation, and which, upon supply of compressed air to the chamber 30 is locked in position by a locking unit 20 so as to enable the pressure in the chamber 30 to act on the said opposite face of the piston 9 in order to release the brake. As shown, the locking unit consists of a conical annular surface 21 on the lockable annular piston 16, balls 22, a corrugated leaf spring 23 the axial force of which is less than that of the return spring 19, and an annular extension 21 of the piston 9, the parts of the unit assuming the positions shown when the brake is released. During normal braking, air is fed via a connection 31 to the chamber 32 whereby the extension 21 presses the balls 22 against the spring 23 to free the balls from the surface 21 and cylinder wall 15 so that the pistons 9, 16 carry out a braking stroke against the force of the spring 19, the brake being applied by the piston-rod 6. If the vehicle wheel locks during braking, air is fed via connection 25 by a wheel lock sensing device, comprising, e.g. an inert mass, to chamber 26 and via openings 27, chamber 28 and passages 29 into chamber 30 to act on piston 9 in opposition to the pressure in chamber 32. The pistons 9, 16 move away from each other and the surface 21 urges the balls against the wall 15 to retain the piston 16 in a fixed position and to form a fixed wall against which the piston 9 abuts, the latter returning towards the original position thereof when the pressure further increases in the chamber 30 whereby the brakes are released; this cycle of braking and releasing is repeated a number of times according to the pulses of the wheel-lock sensing device. In modifications, (a) the pistons (42), (43), Fig. 2 (not shown), are located at opposite ends of the cylinder of the actuator and the balls (57) of the locking unit (40) act on the piston tube (47), air during normal braking being admitted to a chamber (46) to act on the piston (42) and to a chamber (54), and (b) the locking unit comprises a plurality of segments with friction linings which are clamped on to the piston tube, a ring of rubber being mounted on the unit to serve as a noise damper.

Filed: 1938-12-06
Abstract: 510,659. Lubricating. CUKOR, K., and LAVINGTON, R. Dec. 6, 1938, Neo. 35492. [Class 12 (iii)] In order to facilitate the re-starting of an internal combustion engine, the lubricating oil in the crankcase is pumped, when the engine is stopped, into a heat-insulated storage tank, which may be electrically heated, and returned to the crankcase just before re-starting. A lamp is provided for indicating when the crankcase is empty, and means are also provided to prevent the engine from being re-started until the oil is returned to the crankcase. Thus, the oil is withdrawn from the crankcase 1 through pipes 3, 9 connected to a hand-actuated valve 4. by an electrically-operated diaphragm pump 10, mounted on the instrument board 12 and controlled by a press-button 35, and discharged to the tank 18 through pipes 14, 17 also connected to the valve. The valve consists of a rotatable plate 42, Fig. 9, mounted on a spindle and disposed in a casing to which the pipes are connected. As the oil passes into the tank, the float 56, Fig. 14, therein rises and closes the circuit through the indicator-lamp 37 and the winding 38 of a solenoid the core 23 of which opens the switch 33 in the ignition circuit of a petrol engine or the starting device of a diesel engine. When the engine is to be re-started, the valve is adjusted to the position B and. the solenoid core is moved to close the switch by a hand-lever 26 which abuts against a stop 24 on the core, and which is returned to its normal position by a spring 28.

Abstract: 639,990. Super regenerative circuits. PHILIPS LAMPS, Ltd. Dec. 5, 1946, No. 36013. Convention date, Dec. 8, 1945. [Class 40 (v)] A super-regenerative receiver has, in addition to the normal oscillation producing circuit a separate negative resistance arrangement across the tuned circuit which operates when the receiver is not in a self-oscillatory condition to increase the selectivity. The super-regenerative valve 5<1> has an input tuned circuit 2 coupled to aerial terminals 1 and to a feedback circuit from the anode choke 8<1> through a condenser 9<1> and reaction coil 6. Condenser 9<1> is adjusted to produce self-oscillation. A second valve 5<11> acting as a negative resistance is coupled to the tuned circuit and has its output connected through condenser 9<11> to the reaction coil. This condenser is adjusted so that with valve 5<1> inoperative the Q of the tuned circuit is increased to produce desired increase of selectivity. Valves 5<1> and 5<11> are rendered alternately operative by a square or trapeziumshaped quench voltage wave applied to the cathodes across resistors 10<1> and 10". The output voltage is taken from transformer 7 in the common anode lead. In an alternative single valve circuit (Fig. 2, not shown), valve 5<1> is replaced by a pentode and valve 5<11> is omitted, condenser 9<11> being connected to the screen-grid of the pentode. The quenching voltage is applied to the suppressor grid so that during the negative or quenching half-cycle the space current is diverted to the screen grid to effect the negative damping through condenser 9<11>. The output transformer is connected in the common anode and screen grid circuits. The quench voltage may be produced in the same valve if sufficient additional electrodes are available.
