Title: Power-assisted steering gear
Inventor: ADAMS FREDERICK JOHN
IPC: B62D6/10
Filed: 1989-09-29
Abstract: Steering unit (1) (which may comprise a conventional rack and pinion) has a transmission shaft (5) rotatable relative to a housing (2) about axis (6). An input shaft (20) rotatable in response to a steering input torque has its axis (21) parallel to the axis (6) and eccentric therewith. The transmission shaft (5) has a concentric toothed gear (11) rotatable therewith and engaging with a toothed gear (22) concentric and rotatable with the input shaft (20). The input shaft (20) is rotatable in a carrier (14) pivotally mounted by bolt (15) on the housing (2). In response to rotation of the input shaft (20), a resultant reaction between the engaging gears (11) and (22) pivotally displaces the carrier (14) arcuately about the bolt axis (17). This pivotal displacement serves to actuate, through boss (23) on the carrier and linkage (24), control means (25) for a hydraulic or electric servo motor (9) to assist the intended steering manoeuvre. In a modification the driving engagement between the gears (11) and (22) can be provided by use of an internally toothed gear meshing with an externally toothed gear. <IMAGE>

Title: Methods and apparatus for monitoring a fluid conduit system for leaks
Inventor: STENSTR M THEISS
IPC: F17D5/02
Filed: 1990-02-07
Abstract: A fluid conduit system e.g. the hot and cold water system of a domestic dwelling supplied via a main valve 5 from a source 15 is monitored for leaks by a pressure monitor 2 downstream of valve 4 when no fluid is being withdrawn. A shunt valve 6 is proved in a replenishment path across the main valve, both valves 4 and 6 being actuated under the control of control unit 1. The flow rate capacity of the shunt replenishment path is much less than that through main valve 5. After main and shunt valves 4 and 6 are closed and no fluid is being drawn off from the system, the time taken for the pressure to drop to a predetermined value is measured whereupon the shunt valve 6 is opened and the time taken for the pressure to rise to a higher predetermined value is measured. The leakage volume flowrate is calculated from the two time periods and the two pressures together with known constants for the conduit system.

Title: Rotating vane type door check
Inventor: OHSHIMA KAZUYOSHI
IPC: E05F3/12
Filed: 1991-07-16
Abstract: A back chock and door closure delaying device for a door closure comprises a rotational shaft 3 sealed in a casing 1 having a pair of chambers 5, 6. The rotational shaft 3 is formed with a pair of rotary blades 7 which define high pressure chambers 5a, 6a and low pressure chambers 5b, 6b within the casing, which is filled with a viscous fluid. The rotational shaft 3 has a narrow passage 12 which connects both high pressure chambers 5a, 6a to both low pressure chambers 5b, 6b, a wide passage 10 which connects the two high pressure chambers 5a, 6a and is provided with a regulating valve 14 to regulate the fluid flow through the passage depending on the force applied to the rotational shaft 3. Thus when a strong wind blows the door, the valve 14 closes restricting the flow of fluid through passage 10 thereby limiting the speed at which the door closes. <IMAGE>

IPC: H04N5/20
Filed: 1993-02-01
Abstract: A circuit arrangement for adaptive white-compression of video signals of a colour television apparatus, particularly of a HDTV picture signal generator is described, which has a signal minimum detector circuit 4, 5, 6 in each colour channel.
