Title: Method and apparatus for combustion control
IPC: F23N5/08
Filed: 1981-04-15
Abstract: A method of and an apparatus for combustion control wherein the volume of air for combustion is controlled (13) in accordance with a change (4A, 4B) in the load (6, 9), the volume of air is measured (14), and the volume of fuel for combustion is controlled (18) in accordance with the result of measurement of the volume of air (14), so that control of combustion can be effected in accordance with the change in the load while keeping the ratio of the volume of air for combustion to the volume of fuel for combustion substantially constant. <IMAGE>
Patent GB-2097215-A (GB)
Title: Range finder
IPC: G01C3/08
Filed: 1981-04-16
Abstract: A range finder (Fig. 1) e.g. for a submersible 12 positioned near an object 10 comprises a pair of t.v. cameras 15, 16 spaced apart on the submersible with overlapping fields of view. Camera signals are fed to a control station on a surface vessel in which the camera signals are displayed on a video monitor Fig. 2 (not shown) in the form of interlaced scans. A variable time delay element can be operated to delay the signals from the right hand camera 16 until the images appear at the same place on the monitor. The delay required to achieve this is a measure of the angular displacement of the images and, knowing the separation of the cameras the range of the object can be calculated. Preferably the video signals applied to the monitor are also applied to a correlator which for a range of small fixed time delays correlates the video signals for a "best match" and the delay required to achieve this forms a correlation to the time delay obtained manually during the visual correlation. A change from maximum correlation coefficient may be used to drive the vessel to restore maximum correlation enabling it to be positioned and held. A similar correlation of a frame-to- frame basis of one of the cameras may control lateral positioning and movement. <IMAGE>

Title: Pressure medium pump
IPC: F04B9/04
Filed: 1981-11-11
Abstract: A pump for a fluid pressure medium such as hydraulic oil has a reciprocating piston 4 coupled to be driven by a rotating eccentric 14. The coupling of the piston to the eccentric takes the form of an open annular spring 20 which fits round the eccentric so that should the piston suffer from excessive friction in the cylinder the spring can flex open and reduce the stroke of the piston and therefore the wear. The spring has a small semi-circularly shaped portion which fits round a semi-circular guide- shoe 18 pivoted on the piston. A bearing ring 16 able to rotate on the eccentric is fitted between the spring and the eccentric. <IMAGE>

Title: Vehicle immobilisation device
Inventor: CANINI MARK ALEXANDER
IPC: B60T17/16
Filed: 1983-03-18
Abstract: A device for immobilising a vehicle comprises a valve mounted in a valve casing (6) having an inlet port (7) adapted to be connected to the master cylinder (1) and an outlet port (8) adapted to be connected to the brake cylinders (3) of a vehicle braking circuit by fluid lines (2).

Patent GB-2124321-A (GB)
Title: Friction clutch control compensating for wear
Inventor: GRUNBERG PIERRE
IPC: F16D13/75
Filed: 1983-07-22
Abstract: The invention provides means for controlling the operation of a friction clutch. The clutch is controlled by a linkage (19, 24) having drive means (25 to 28). A tracer (31) is connected to the linkage and is designed to cut off the action of the drive means when it reaches either one of two terminals (29, 30) of an adjustable assembly designed to be progressively displaced by the linkage along a support (34) in proportion to the wear of the friction disc (12) of the clutch. This arrangement provides a control for a clutch wherein the stroke of the linkage is limited to its actually effective zone, whether the state of the friction disc of the clutch is new or worn and therefore enables the required power of the drive means to be reduced. The drive means may comprise an electric motor (28), as shown, or an hydraulic jack. <IMAGE>

Title: Improvements in extruder screws
Inventor: MARVEN ROBERT
IPC: B29C48/03
Filed: 1985-03-08
Abstract: An extruder has a barrel 1 with screw section 9 of large diameter and coarse pitch and screw section 10 of smaller diameter and finer pitch, both separately rotatable therein in the same sense to move material from solid inlet 6c to melt outlet 8c. Sections 9 and 20 are separate, coaxial screws having either separate gear control from a single motor, or separate motor drives through motors 4, 5 separately controlled by gearboxes 20, 21 respectively. Thus feed section 6 of the barrel, fed through orifice 6c with non-uniform scrap polymer is controlled separately from metering section 8 feeding outlet 8c whereby non-uniformity of feed does not overload the extruder. Separate control can be effected by feedback of pressure signals to the motors or gearboxes. End seal 19 can be water cooled. <IMAGE>
