Title: Transmitting information
IPC: G08B21/00
Filed: 1969-06-23
Abstract: 1,210,364. Tyre pressure indicator. MICHELIN & CIE (Compagnie generale des Etablissements Michelin). 23 June, 1969 [21 June, 1968], No. 31658/69. Heading B7C. [Also in Divisions G4, H1 and H3] In an automatic alarm for use in a motor vehicle, the direction of feedback in a circuit 20, preferably mounted on the vehicle chassis adjacent a wheel, is reversed to make the circuit oscillate by an inductive loop 10, preferably mounted on the wheel, when loop 10 is adjacent oscillator 20 and a switch 13 is closed in response to an alarm condition, e.g. pressure and/or temperature. In an alarm condition, oscillator 20 thus produces a burst of oscillation once per revolution of the wheel. Oscillator 20 turns on a Darlington pair 33, 34 and hence a Darlington pair 45, 46 to operate a visible and/or audible alarm 49. Alarm 49 is maintained in continuous operation by a capacitor 50 and a diode 47. Alternatively, the pair 45, 46, may be replaced by a thyristor. The supply to oscillator 20 is maintained constant by a diode 37 and a capacitor 36. A loop 10 may be provided for each vehicle wheel and the associated oscillators 20 may be connected to a single alarm on the vehicle's dash-board (Fig. 6, not shown). Alternatively, a single oscillator may have several feedback paths, each associated with a loop 10. A loop 10 is formed as conductive spirals printed side-by-side on one or on opposite sides of a circuit board (Fig. 3, not shown) which may be insulatively coated and integral with means for actuating switch 13. Switch 13 may be actuated by a pressure-sensitive device (76) flexibly connected to a tyre inflation valve (74, Fig. 7, not shown). Oscillator 20 and Darlington pair 33, 34 are embedded in an insulative mass (30, Fig. 5, not shown) with two projecting electrical terminals 31, 32 being used to mount oscillator 20, earthing terminal 32 having a screw-thread, and terminal 31 an insulative spacing collar.

Title: Automatic coin-cheking mechanism
IPC: G07F1/04
Filed: 1976-08-02
Abstract: 1523208 Coin-checking mechanism AUTELCA AG 2 Aug 1976 [19 Aug 1975] 32055/76 Heading G4V An automatic coin-checking mechanism is mounted vertically as shown in Fig. 3 and has a coin insertion channel 1 and a coin checking chamber 2. A wall 3 of the channel and chamber is pivotally mounted and is normally positioned in a rest position 311 or a locked position 3<SP>1</SP>. In operation a coin 9 is inserted into channel 1. If it is metallic this is sensed by coil 13 and a run-through signal is produced. If it is non- metallic it passes direct to a return channel 7. The run-through signal operates a pressure device, 22, 23, 24 to move wall 3 from rest position 3<SP>11</SP> to locked position 3<SP>1</SP> against the action of leaf spring 21. Wall 3 has a projection 27 that co-operates with stop 28 to hold the coin correctly positioned relative to coils 14 and 15. If no acceptance signal is produced after a predetermined time the pressure device releases wall 3 which is moved to its rest position by spring 21. The "coin" then passes to return channel 7. If there is an acceptance signal a flap moves from a rest position 6<SP>11</SP> into an acceptance position where plate 34 opens a storage channel 8. Also pin 43 moves into the coin path to prevent further coins entering the checking chamber and second plate 35 is positioned to direct the accepted coin into channel 8. The pressure device releases wall 3 and the coin passes to the storage channel. If another coin has already been inserted pin 43 cannot move to its correct position and after a predetermined time wall 3 is released and the coins pass to the return channel. The flap is moved by a draw device 31, 32, 33 against the action of spring 30. At the end of the channel 8 there is an arrangement such that an accepted coin can be passed to the return channel 7 or to a further store. The channel 8 can contain a multiple of coins. When full counter coil 46 produces a continuous signal that prevents the acceptance of further coins. Plate 34 has a cutting edge that co-operates with a cutting edge on a fixed counter-knife 42. The wall 3 has an angle piece 16 that has a projection 19 that enters chamber 2 to allow a coin to pass to the checking area but prevent return movement.

Filed: 1961-09-12
Abstract: 1,034,272. Washing machines. HOOVER Ltd. Sept. 11,1962 [Sept. 12,1961], No. 32758/61. Heading D1A. [Also in Division E2] A detergent dispenser for a washing machine includes a valve 12 for allowing detergent to be discharged, a latch device comprising a magnetic circuit including a movable part connected to the valve member and a fixed part, biasing means 25 tending to separate the movable part from the fixed part and open the valve, a permanent magnet 16 in the circuit holding the two parts together in a latched position to keep the valve closed, an energizing coil 21 linked with the magnetic circuit and means for applying a de-magnetizing current to the energizing coil to release one part from the other and allow the valve to open. As shown the dispenser comprises a body in the form of a hopper 10 the lower end of which communicates through a flexible hose 11 with the washing machine container. The valve 12, shown as a flap valve, is connected to the hopper by means of a pivot pin 14 which carries an arm 15 extending parallel to the valve, the permanent magnet 16 being secured near its end. The magnet is preferably of the ceramic type and has pole plates 17 secured to its north and south faces and interposed between flanges on the arm 15. Secured to the side of the hopper is a U-shaped core comprising pole plates 19 and a sleeve 20 surrounded by the energizing coil 21 and mounted so that its pole pieces are presented to the pole pieces of the permanent magnet. The biasing means is a torsion spring 25 surrounding the pivot pin and this tends to turn the valve to its open position and the arm 15 with the permanent magnet away from the U-shaped core. The energizing coil is connected to suitable contacts of an automatic timer of the washing machine and in use a charge of detergent is contained in the hopper and supported by the valve. The permanent magnet is in contact with the pole pieces of the U-shaped core and at a suitable point in the washing machine cycle alternating current is applied to the energizing coil and when the flux due to the coil produces a north pole opposing the north pole of the magnet and the south pole opposing the sole pole, the flux due to the magnet is neutralized and the spring and weight of the detergent opens the valve. The hopper is provided with a hinge lid 26 connected to the valve 12 by a tension spring 27 and a nylon cord 28 arranged so that when the lid is raised to fill the hopper with detergent the valve is raised and causes the magnet to engage the core to hold the valve in such raised closed position.

Abstract: 428,302. Variable - speed gearing. HEYDEN, H., 1109, Grangefield Avenue, Bradford, Yorkshire. Nov. 25, 1933, No. 33000. [Class 80 (ii)] Variable-speed gearing comprises an epicyclic train of which the sun gear T, Fig. 1, is fast on a driving-shaft S, the carrier O<1> of the planets T<1> is fast on a driven shaft O<2>, and the annulus T<2> is prevented from rotating backwards to yield a definite low speed, and is alternatively driven forwards elastically to yield speeds above that low speed which vary automatically with the load up to solid drive. The reaction of the annulus T<2> on low speed is transmitted through an inner ring F<2>, Fig. 2, a one-way clutch G, an impulsive ring F<1>, a one-way brake K, and an anchored ring F<3> connected to a fixed casing H by springs B. A flywheel D, Fig. 1, fast on the shaft S is connected by linkages D<1> &c. to weights W, W<1> strapped upon eccentrics C, C<1> so that the weights are drawn round loosely over the eccentrics. These eccentrics C, C<1> are connected by a sleeve V to the impulsive ring F<1> to which alternate forward and backward rotary impulses are imparted by the interaction of the rotary weights and the lagging eccentrics. The forward impulses are transmitted through the one-way clutch G to drive the annulus T<2> forwards, and so increase the speed transmitted. The backward impulses are taken by the oneway brake K and springs B by which they are returned to augment the next forward impulse of the impulse ring F The effect of the masses and springs is that the drive is elastic and varies with the load up to the point at which the parts turn solid inside the anchored ring F<3>.
