Patent GB-2028560-A (GB)
Title: Engine-driven vehicles
IPC: B60K28/10
Filed: 1979-08-08
Abstract: In an engine-driven vehicle having an hydraulic braking system incorporating a pedal-operated master cylinder for applying the brakes, it is a problem that the braking system may fail while the vehicle is idle, and this is only discovered the next time the vehicle is used, with potentially dangerous consequences. Thus the vehicle is provided with pressure sensing means (3) for sensing pressure in the braking system, and inhibiting means for rendering the vehicle drive means inoperative when the pressure in the system is below a predetermined value. The inhibiting means may prevent the engine from being started, by isolating one of the services to, or a part of the engine. In one construction it comprises a movable contact preventing the ignition circuit from being completed. Alternatively the inhibiting means may inhibit the vehicle transmission by preventing selection of gears. <IMAGE>

Title: Sheet counting method and apparatus
IPC: G06M7/06
Filed: 1979-09-13
Abstract: A method of counting a succession of sheets passing along a flow line (the sheets being normally spaced but including some overlapping sheets), comprises determining the position of a double thickness in relation to the total length of the sheet in the flow direction. A count of two is added to the count of sheets if the double thickness is found to be symmetrically placed in relation to the total length of the sensed "sheet" and has a length consistent with the amount by which two single sheets would have to overlap to have a total length equal to the sensed "sheet" length. If these requirements are not met, depending on the results of the measurements either a count of one is added or an error signal is generated. <IMAGE>

Title: Coin mechanism
IPC: G07F5/06
Filed: 1979-12-12
Abstract: A coin freed mechanism for a vending machine in which the mechanism operates with a combination of coins with different diameters, for example 10p and 50p coins, in which the coins enter the mechanism and are supported on one side by a ridge 16 (for 50p coins) and a portion 24 (for 10p coins), attached to a pivotally mounted 'L' shaped supporting member 53, and on the other side by an edge 18. The coin supporting edges on either side of the coins are connected to the member 12 which is secured to a fixed part of the machine. In use, when the correct number of coins are present in the mechanism, plates on the drawer cause the coins to move in the direction to bear against a cammed surface 40 of a pivotally mounted lever 28. A stop 34 on the lever 28 clears a ratchet attached to the drawer to allow the drawer to be opened. When the coins reach an edge 44 of the second member 12 they drop out of the mechanism. <IMAGE>
