Title: An actuator assembly for a fluid control valve
Inventor: HAYES MICHAEL JOHN
IPC: F16K7/06
Filed: 1982-07-05
Abstract: An actuator assembly for a fluid control valve has a tube pinching plunger 7 operated by a lever 45 through the intermediary of a linkage. The linkage has three links 21, 37, 22 arranged so that the interconnection points 40, 41 of the intermediate link with respect the outer two links and a pivot point 19 of one of the links which is attached to the operating lever lie in a common plane. In this manner, force exerted upon the plunger is unable to break the line of the links whereas pivoting motion of one of the links by the operating lever enables a mechanical advantage to unlock the plunger and thereby permit the plunger to travel rearwardly for opening the tube. A handle 51 is provided having two stable states so that the plunger may be locked into an open valve position by depression of the handle. <IMAGE>

Title: Hydraulic anti-skid braking systems for vehicles
Inventor: FARR GLYN PHILLIP REGINALD
IPC: B60T8/74
Filed: 1983-05-19
Abstract: In an hydraulic anti-skid braking system, flow of fluid from a master cylinder (19) to a vehicle brake (23) is modulated by a modulator assembly (2) in accordance with skid signals from skid sensing means. The modulator assembly (2) incorporates a dump valve (4) for dumping fluid from the brake-line when a skid signal is operative, and the dump valve (4) is movable against the loading of spring means (64, 65) between a supply position in which the master cylinder (19) is in communication with the brake (23), an intermediate closed position in which the supply (19) is isolated from the brake (23), and a cut-off and dump position in which the master cylinder (19) is isolated from the brake (23) and pressure is dumped from the brake to an expansion chamber (48). The spring means are arranged so that the dump valve (4) can move from the supply position only into the intermediate closed position in response to a skid signal not exceeding a predetermined value and into the cut-off and dump position only in response to skid signal in excess of the said predetermined value. The dump valve (4) is operated by a lever (62) of a flywheel-overrun skid- sensing device (Figs. 1; 2 not shown). The system also includes a double acting pump (3) and an expansion piston (11). The dump valve (4) and expansion piston (11) may be combined (Figs. 5, 6 not shown).   <IMAGE>
Patent GB-2122273-A (GB)
Title: Minimising the effect of temperature changes upon fluid bearings
Inventor: MOHSIN MOHAMMED EZZAT
IPC: F16C32/06
Filed: 1983-06-10
Abstract: A hydrostatic journal bearing with two opposed bearing pads in which the typical tendency of the bearing clearance to change due to variation in the viscosity of the operating fluid, brought about by temperature change, is counteracted by causing the sum of the pressures (p1, p2) existing at the two pads (22, 23) to be held to a constant value. Typically this value is equal to that of the pressure (ps) of the supply (27). The supply may be connected to the two pads by way of separate adding valves (40, 29) which may be arranged in parallel with restrictors (41, 28) which are themselves in series with the pressure source (27). Such restrictors may be fixed but may also with advantage be controlled by reference to the pressure existing at their respective pads (22, 23), provided they respond symmetrically to variations of fluid temperature and so give rise to no change in the relative position of the bearing members in response to such variations. Alternatively only a single adding valve may be used, which advantageously may provide a third, reference output pressure (po) supplied to the pads (22, 23) in parallel with their respective basic pressure supplies (p1, p2). <IMAGE>

Title: Devices for use in cardio pulmonary resuscitation
Inventor: MANLEY ROGER EDWARD WENTWORTH
IPC: A61M16/00
Filed: 1984-08-02
Abstract: A device for controlling the delivery of pulses of respirable gas to a face mask for use in cardio pulmonary resuscitation has a gas inlet 1 which leads through a gas pressure-controlled spool valve 3 and a flow regulator 7 to a manually operated valve 9 which has an outlet 10 which, in use, is connected to the face mask. A by-pass connection 13, 6, 15, 19 leads from the inlet 1 through a second flow regulator 17 to a reservoir 20, and a line 5 leads from the reservoir 20 to a pilot port of the valve 3. To supply a pulse of gas to a face mask during resuscitation, the valve 9 is opened by a pushbutton 12 and gas flows through the valve 3, which is opened by pressure from the reservoir 20, and thence through the regulator 7 and the valve 9. A further much smaller flow of gas flows from the reservoir 20 through the regulator 17. The pressure in the reservoir 20 and the line 5 thus falls and as soon as the pressure reaches a predetermined value, the valve 3 closes automatically to shut-off the main gas flow. This happens after just less than 0.5 second so that the duration of the pulse of the gas supplied each time the valve 9 is opened is automatically limited. A gas unit, Fig. 2, not shown, may be used instead of valve 3. <IMAGE>
