Title: Coin freed sale apparatus
IPC: G07F11/02
Filed: 1919-02-05
Abstract: 142,553. Woodward, G. A., and Wagstaff, J. S. Feb. 5, 1919. Delivery of articles stored in piles; coin action, mechanical-connexion.-A coin-freed apparatus comprises two compartments 3, 4 of which the former contains the coin-operated mechanism and the latter the stack of goods 35 and the delivery drawer 31. The coin mechanism comprises a stationary and U-shaped frame 6 in the limbs of which are slots 7, Fig. 3, with pairs of studs 8 on one side thereof. A slidable U-shaped frame 9 is mounted on the frame 6 by a sleeve 1.0 engaging a rod 11 secured to the frame 6, and is operated by the depression of a handle 13. Studs 14 in the limbs of frame 9 pass through the slots 7 and form pivots for a rotatable U-shaped coin-carrier 15. Slots 17 in the limbs of the coin-carrier engage the pins 8 when the frame 9 is depressed, and cause the carrier to be rotated through half a revolution. A coin is inserted through a slot 20 and is held by spring jaws 18 on the carrier. A weighted catch 21 normally holds the carrier against the stationary frame 6, but is pressed back by the insertion of a coin. A plunger 24 at the base of the chamber 3 is spring-mounted above recesses 28 in the limbs of locking-levers 26, the ends 29 of which engage the drawer 31. Bell-crank levers 32 with hooked ends 32<1> are mounted on each side of the rod 24 and engage the coin when it is depressed upon them and against the plunger 24 by the operation of the handle. By the pressure of the coin, the bulbous end of the plunger is moved to force the levers 26 apart and release the drawer, the coin being tipped out of the jaws 32<1> by the catch 21 on the return stroke of the frame 9. Insertion of coin in empty apparatus, preventing.-To prevent the insertion of coins after withdrawal of the last article 35, a frame 36 is pivoted adjacent the stack of goods with a long arm engaging the packets, which is tilted when the last packet is removed so as to throw a short arm 37 into the path of the frame 9 and prevent its return, so that it is retained in a position such that a shutter 38 thereon covers the coin slot. Fraud, preventing.-In order to prevent abstraction of more than one packet at a time, a plate 39 controlled by a spring 40 is mounted to bear on a cam on the top of the drawer, so that as a packet is withdrawn the plate drops.

IPC: G01F15/02
Filed: 1925-02-02
Abstract: 235,804. Imray, O. Y., (Veeder Manufacturing Co.). Feb. 2, 1925. Counters actuated by reciprocating mechanism; affording several rates of actuation; associated counters.-A counting mechanism for registering the volume of liquid delivered by a pump is actuated by a pair of oscillating levers and is provided with a compensating device to correct for variations in the stroke of the pump to deliver a unit volume. As shown, the rack bar of the pump is connected with an arm c on a shaft c' that carries a pinion c<2> in gear with a segment d pivotally mounted on a sleeve b<2> surrounding the spindle a<2> of the indicating pointer a<1>. Pivoted to the segment at d<2> is a lever e slotted at its upper end e' to receive a fulcrum block f pivotally mounted on an arm f<1>. The arm j<1> is pivoted at one end f<2> and is slotted at its otber end f<3> to engage, an eccentric pin f<4> on a manually adjustable shaft f<5>. Rotation of the shaft f<5> raises or lowers the fulcrum block in order to vary the angular movement of the lever e with respect to that of the segment d. The movement of the lever e is transmitted through a link e<2> to an arm g mounted concentrically with the shaft a<2> and operatively connected through a friction ball clutch g<2> to a disc h fixed to a sleeve h<1> provided with a pinion h<2> engaging the actuating pinion a<4> of a totalizing- counter a<3>. Backward movement of the disc h is prevented by a retaining clutch g<3>. The disc h frictionally drives the shaft a<2> to actuate the pointer a<1>. To re-set the pointer after each complete operation, the shaft a<2> carries a pinion i that co-operates with a mutilated pinion i<1> on a sleeve i<3> mounted on the pin b<4> supported by the frame member. A ratchet wheel on the sleeve i<1> prevents reverse movement of the sleeve, the forward movement, being effected by a bevel pinion i<6> thereon and a similar pinion i<7> on a spring- controlled shaft i<8>. The pinion i<7> is free on the shaft i<3>, but is rotated therewith by a pin i engaging a slot in the hub of the pinion when the shaft is pushed in and rotated. The shaft i<8> is held in the normal position by a pin i<11> thereon engaging a notched plate i<12>.

Filed: 1964-01-23
Abstract: 1,043,824. Frequency modulation; transistor oscillating circuits. SONY CORPORATION. Jan. 23, 1964, No. 3057/64. Headings H3R and H3T. Two transistor oscillators 5a, 5b of different nominal frequency each include a voltage variable capacitor 10a, 10b to which the same modulation is applied to alter the capacities and hence the frequencies in different directions; then the frequency difference of the two modulated frequencies is taken. The modulation may be a video signal and applied to the two oscillator capacitors 10a, 10b through filters 30a, 30b tuned to the unmodulated frequencies of the oscillators, and whose effect is that the impedance of the external circuit between collector and emitter of each oscillator tends to be constant during the oscillator frequency changes, and any amplitude modulation is small. The oscillators may be Colpitts type with tuning capacitors 11a 11b, or of Clapp type, and the outputs are derived from emitter circuit filters 15a, 15b with band pass centred about the mid-frequency of the frequency modulation. The difference frequency taken from mixer 31 is filtered at 38 and after amplifying at 39 may be magnetically recorded on tape.

Title: Improvements in or relating to inductor relays
IPC: H01H51/20
Filed: 1930-02-04
Abstract: 338,811. Associated Electrical Industries, Ltd., (Assignees of Mattingly, H. W.). Feb. 4, 1929, [Convention date]. Addition to 312,239, [Class 38 (v), Electric switches &c.]. Master control systems for continuous-current motors only; controlling travel for a fixed distance.-A lift C is controlled by inductor relays located thereon and co-operating with inductor plates in the lift shaft. The relay armatures carry rollers for engagement by, fixed cams whereby operation of the relays is made positive at the terminal floors and independent of the operator. A Ward-Leonard set comprises a motor driving a generator, the armature G<1> of which energizes through a cumulative-compound winding GSF (for obtaining constant speed irrespective of load), a lift motor EM<1> which operates the lift C. A winding GAF is adapted, when energized, to counterbalance the field GSF and residual magnetism, and a further winding GF is arranged to be separately energized from the lines L1, L2, with or without a resistance R for intermediate speed of the lift C. To move the lift from the first-floor (terminal) position shown to the second floor, the operator moves the switch Cs clockwise to energize the up-direction switch 1 from L1 over lead 41, contacts 42 - - 44, winding of switch 1, contacts 47 of stopping inductor relay URS, lead 49, to line L2. Switch 1, on closing, makes a holding circuit for itself over contacts d and lead 50, and a circuit for winding GF over lead 53, contacts b, lead 55, resistance R, winding GF, contacts a of switch 1, and lead 59. The generator is, therefore, excited and drives the lift-motor at an intermediate speed upwards, whereupon the operator moves the switch Cs further to connect the speed relay 3 over contact 60 and contacts 63 of inductor relay UR. The relay 3, on closing, makes a holding-circuit for itself over contacts a and short-circuits at b the resistance R, so that the lift runs at full speed. As the lift approaches the second floor, the switch Cs is returned to the position shown, so connecting up the coils of relays UR, URS over the closed contacts e of switch 1 and lead 75. The inductor UR<1> causes contacts 63 to open and de-energize the relay 3, which thereupon reinserts the resistance R and shows up the lift. The plate URS<1> then causes contacts 47 to open and deenergize the switch 1, which opens at a the winding GF and connects at c the winding GAF across the generator. A magnetic brake (not shown) effects final stoppage. As the lift approaches the terminal floor, the fixed cams UR<11>. URS<11> act on the rollers of the relays UR, URS to bring about the same cycle of operation. Downward travel is controlled by relays 2, 3<1> and inductors as DR<1> in a similar way. A single relay having four armatures mav replace the four relays shown on the lift C in Fig. 2.

Title: Improvements in or relating to means for preventing the stalling of compression-ignition engines, of which the suction is utilised in vehicle braking systems
IPC: B60T13/48
Filed: 1935-02-05
Abstract: 451,424. Preventing stalling. ASSOCIATED EQUIPMENT CO., Ltd., Windmill Lane, Southall, Middlesex, RACKHAM, G. J., Jeffries, Bourne End, Buckinghamshire, and DACK, W. S., 49, Skeltons Lane, Leyton, London. Feb. 5, 1935, Nos. 3766/35 and 2732/36. [Class 7 (ii)] In a motor - vehicle compression - ignition engine, which supplies vacuum for brake operation by closing a normally-open throttlevalve 17 in the air-intake passage 12, a sufficient supply of air is maintained to all the cylinders to prevent stalling of the engine. The throttle valve 17 is closed by a spring when a tappet rod 46 is lowered by operation of the brake pedal 14 against a spring 51, a pin-and-slot connection 49 with the brake-rod 16, allowing the spring to be immediately effective on release of the pedal 14. A pipe 22 conveys vacuum from an induction passage 13 to the vacuum reservoir through a ball valve 27, Fig. 2, the air supply to the cylinders being maintained by orifices 34, regulated by an adjustable needle valve 33, and provided with a dust cover 37 ; the fitting 23 enclosing these parts may be attached to the main inlet passage 12. Alternatively, the air supply may be maintained by providing an adjustable stop, preventing complete closing of the throttle valve, or by perforations in the valve itself. Alternatively, the throttle valve 17 may be opened by its spring and closed by the brakepedal, a lost-motion device being provided to allow further movement of the pedal. The coupling between the pedal and the valve may be electrical, on electric switch being arranged so that a solenoid is energized during initial movement of the pedal and remains energized during the whole travel thereof. It may be hydraulic, a byepass for the pressure fluid allowing further movement of the pedal after initial closing of the valve.

Title: Automatic application of pressure in laundry and like presses
IPC: D06F71/06
Filed: 1946-02-06
Abstract: 607,493. Ironing-presses. HOWLETT, E. J. and GLEDHILL, H., GLEDHILL, N. R., and GLEDHILL, M., (trading as THOMAS'S). Feb. 6, 1946, No. 3770. [Class 138(ii)] Relates to laundry and like presses in which a head 1 is first moved by power into position over a buck 3 in a direction transverse to the direction of the subsequent operative pressure, a fluid-operated pressure cylinder 5 then coming into action in order to apply pressure. According to the invention, a valve 40 is automatically operated by means carried by a part moving with the head 1 so as to admit pressure fluid to the cylinder 5 when the head reaches its operative position, the pressure then causing a movement which enables the operator thereafter to return the valve to its original position so as to relieve the operative pressure in the cylinder and re-set the operating means. As applied to the press described in Specification 583,516, the head is carried by a lever arm 2 adapted to be swung to operative position by power derived from an auxiliary pressure-fluid cylinder 4, after which the main pressure cylinder 5 acting at the pivot 6 of the lever arm 2 draws down the assembly so as to apply pressure. The valve 40 is of double-headed type, having a pressure-fluid connection at one end 11, an exhaust connection at the other end 42, and an intermediate connection 12 leading to the main cylinder 5. The valve is normally held in the cut-off position against the action of a spring 48 by a trip lever 46 pivoted to the end of a lever 44 which carries the tappet rod 43 of the valve. When the head 1 is swung to operative position, a lever 50, which is resiliently pivoted on an extension 49 of the lever arm 2, disengages the trip lever 46 so that the valve 40 is opened and pressure is applied. The result of the application of pressure is to lower the arm structure 2 and bring the end of the lever 50 below the trip member 46. A pivoted lever 34. which is connected by a link 56 to an extension 55 of the lever 44, can then be operated to re-set the trip mechanism and return the valve 40 to its original position. When two machines are worked in tandem, the lever 34 is operated by a pressure cylinder 14 which is controlled from the second machine as described in Specification 607,492.
