Title: Actuator for a shoe-drum brake
Inventor: INGRAM BRIAN
IPC: F16D65/22
Filed: 1982-11-12
Abstract: An actuator for a shoe-drum brake has a pair of pistons (10, 11) separable by fluid under pressure applied to chamber (12), and with a friction device e.g. split annulus (24) frictionally engaged against the internal wall of cylinder (9) and a pair of resilient elements e.g. washers (25, 26) disposed one at either side of the device (24) to engage the device (24). The washer (25) deflects in resisting outward movement of the piston (11) relative to the device (24) until washer (25) becomes rigid, following which further outward movement of the piston in one direction moves the device (24) along the cylinder. The device (24) acts as a back-stop preventing excessive inward movement of the pistons. The washer (26) acts to cushion inward shock loads. As shown, the pistons (10, 11) are operatively interconnected by an automatic adjuster of drive ring type - the backlash provided in the adjuster is equal to piston movement permitted by washer (25) plus any deflection occurring in brake components during brake actuation. <IMAGE>

Patent GB-2119927-A (GB)
Title: Liquid flow meter
Inventor: WOOD JOHN MICHAEL
IPC: G01F1/704
Filed: 1983-05-03
Abstract: The flow rate of liquid 14, in the direction indicated by arrow 52, through bore 12 of a capillary tube 10 (which flow rate may be very small, e.g. of the order of 1ml. per hour) is determined by sensing the arrival of a gas (air) bubble 46 at a second sensor 38 which stops a timer 44 and actuates a piston 24 to introduce into the bore 12 a subsequent bubble 40 whose arrival is sensed by a first sensor 36 which starts the timer 44. Thus a succession of bubbles are introduced into the liquid 14 and the timer 44 senses the time they take to move between the sensors 36, 38. These times, as well as fixed or constant data, such as the capillary tube geometry, the spacing between the sensors 36, 38 and ambient temperature, supplied by data store 48, enable a microprocessor 46 to compute the precise liquid flow rate. Alternatively, just one sensor is present which is adapted to sense the leading and trailing edges of the bubble. <IMAGE>
