Title: Torque-limiting clutch
Inventor: FORTUNE DAVID JOHN
IPC: F16D7/08
Filed: 1988-09-30
Abstract: A torque limiting clutch in which relatively rotatable and axially movable drive members 18, 20 are interconnected by balls 23 and are axially biased together into torque transmitting engagement by air pressure on pistons 34 which pressure is released when the drive members move axially apart on disengagement when torque exceeds a predetermined value. The balls are guided by a cage 21 so as to be maintained out of engagement with one drive member after disengagement. The cage 21 is thinner than the radius of the balls and springs 40 act on the cage and one drive member to maintain the balls out of engagement with the one drive member, the cage being free to rotate relative to both drive members during disengagement. The drive may alternatively be interrupted by a mechanism which disconnects the air supply under the control of an operator. <IMAGE>

Title: Controlling the loading of a non-driven axle in a multi-axle vehicle
Inventor: CULLOTY DENIS JOSEPH
IPC: B62D49/00
Filed: 1989-08-22
Abstract: A multi-axled vehicle has a driven axle associated with load sensing means and a non-driven axle having a pneumatic suspension (8) connected to an air supply of the vehicle. This connection is via two pressure control valves (14, 15) connected in series. The input pressure to the first valve (14) is determined by the load sensing means. The pressure control valves (14, 15) are each such that they give an increasing output pressure (for charging the pneumatic suspension) with increasing input pressure only beyond a predetermined value thereof and thus the two valves in series increase the sensed load at which the pneumatic suspension is supplied with pressure relative to that which would be obtained with only one valve. <IMAGE>

Title: Micromachined solid state vibrating element sensors
Inventor: WILLSON JOLYON PETER
IPC: G01D3/036
Filed: 1989-09-28
Abstract: A solid state sensor, micromachined in silicon, comprises first and second beams 16, 18 which can be optically excited into resonant vibration. The first beam 16 is arranged to be acted upon by a diaphragm 14 so that the tension in it, and therefore its resonant frequency, is affected by the pressure applied to the diaphragm. The second beam 18 is provided for temperature correction purposes, and to this end is positioned close to the first beam but free at one end, so that it is insensitive to the pressure applied to the diaphragm, while being subject to the same temperature variations as the first beam. Additionally, the second beam is positioned sufficiently close to the first beam that it can be optically excited simultaneously with the first beam via a single optical fibre. In an alternative arrangement, the two resonant beams may be perpendicular to each other. An electronic system for operating the sensor is also disclosed. <IMAGE>

Patent GB-2242503-A (GB)
Title: Non symmetrical float
Inventor: CLARK PETER JAMES
IPC: F16K33/00
Filed: 1990-02-27
Abstract: An actuator 6 for a fluid flow control valve device 1 or a switch comprises buoyant parts 8' and 8'' and a mounting bar 5 so mounting the buoyant parts 8' and 8'' upon a spigot 4 that the actuator 6 is turnable about the spigot 4 between a lowered condition and a raised condition. The arrangement is such that, with the actuator 6 disposed in the fluid in its raised condition, and with the fluid level falling from an upper position to a lower position, the buoyant parts 8' and 8'' produce a sufficient upward buoyancy moment in one sense about the spigot to retain the actuator 6 in its raised condition until the fluid level approaches its lower position, whereupon the buoyant parts 8' and 8'' no longer produce an upward buoyancy moment in that one sense sufficient to retain the actuator 6 in its raised condition and the actuator turns to its lowered condition. The actuator 6 has the advantage that a relatively large drop in fluid level is required before the actuator 6 is able to fall from its raised condition towards its lowered condition, so that the actuator 6 performs a relatively rapid downward turning from its raised condition. <IMAGE>

Title: Dynamic memory bitline precharge scheme
Inventor: FOSS RICHARD CHARLES
IPC: G11C11/4094
Filed: 1991-04-05
Abstract: A method and apparatus for precharging DRAM bit lines 4A, 4B and data buses 8A, 8B from the same voltage source Vpc, eliminates a separate bit line precharge source and the bit line precharge conduction paths. The precharge source for the data buses is coupled to the data buses and at the same time access transistors 9A, 9B normally used to couple the bit line logic voltage to the data buses for reading or writing are enabled, in order to cause coupling of the precharge voltage source through the data buses and the access transistors to the bit lines during a precharge interval. This both precharges and equalizes the voltage on both complementary data buses and both complementary bit lines. To block write data into the memory array, the data to be written is applied to the data buses after precharging with the access transistors remaining enabled. <IMAGE>
