Patent GB-2131897-A (GB)
Title: Clutch release lever arrangement
Inventor: FULFORD GARY
IPC: F16D21/06
Filed: 1982-12-11
Abstract: A cltuch cover assembly with a cover member (10), a pressure plate (11), spring means (12), and release levers (26) for withdrawing the pressure plate against the action of the spring means, wherein the connection between each of the release levers and the pressure plate is provided by a flexible element (29) such as a strip of spring steel. Such a connection overcomes the problem of lost motion arising in links and pivot points, and can provide a biasing force to oppose the effect of centrifugal force on the release levers.

Title: Axial tubular compensator
Inventor: BERGER PETER
IPC: F16L51/02
Filed: 1983-01-14
Abstract: An axial tubular compensator, the axial extension of which for a compression test is blocked by a radially resilient spring ring (11) acting between stop surfaces on an end sleeve 2 and a ring 6 carried by a guide tube 5. When the compensator warms up on first being used, the spring ring automatically moves from its blocking position into another radial position (shown in dotted lines in Fig. 2) and thus releases the axial displaceability of the compensator in both directions. <IMAGE>

Title: Immunometric method for the determination of a hapten
Inventor: HAMMOND GEOFFREY LEWIS
IPC: G01N33/53
Filed: 1984-05-08
Abstract: Haptens may be determined by a competitive binding immunometric technique in which a sample of hapten to be determined is incubated with a labelled antibody to the hapten and with a conjugate of the said hapten bound to a solid support, the protein present in the said conjugate being different from that bound to the hapten during raising of the antibody. The conjugate is conveniently immobilized by binding to an antibody to the protein portion thereof which is itself bound to a solid support. The method may be calibrated by use of samples containing standard amounts of hapten.

Title: Apparatus for raising and lowering a load
Inventor: GOLDSCHMIDT GIDEON
IPC: B66F19/00
Filed: 1984-01-27
Abstract: Apparatus for raising and lowering a refuse container arranged to be kept below ground level comprises a load platform (9) suspended from cable (17), a counterbalance weight (8) suspended by cable (18), a conical drum (16) on which the counterbalance cable (18) is wound, and a drum (20) of fixed diameter on which the load cable (17) is wound. In normal use the weight of material on the load platform (9) varies according to how full the refuse container is. To take account of this, the counterbalance weight cable (18) is wound about the conical drum (16) at different positions along its axial length. This is achieved by a feed puley (13) on a balance rod (3), the balance rod (3) being moved along its length automatically by the effect of increase or decrease of tension in the load cable (17) as a result of increase or decrease of load. In a modified apparatus (not shown) the axial position of the cable (18) is kept constant and the conical drum is moved along its axis relative to the cable (18).

Title: An earth terminal for satellite communication systems
Inventor: GARROOD DAVID
IPC: H01Q1/32
Filed: 1985-02-01
Abstract: An earth terminal for a geostationary satellite communication system incorporates an oval or elliptical shaped antenna 1 whose horizontal dimension d1 is greater than its vertical dimension d2. The relatively small dimension d2 facilitates transportation of the antenna whilst giving a beam shape which is broader in a direction perpendicular to the geostationary orbit of the satellite than in a direction parallel thereto. This special beam shape accommodates small movements of the satellite perpendicular to the orbit whilst giving the necessary angular resolution in the direction of the orbit to avoid interference with other satellites in the geostationery orbit. The antenna parts may be folded down to facilitate transportation. <IMAGE>

Title: Analog display circuit including wideband amplifier for a high resolution raster display
Inventor: HOLMES RICHARD E
IPC: G09G1/00
Filed: 1985-03-22
Abstract: In a high resolution raster display (e.g. for air traffic control) a central processor (22) provides image data, a digital image processing circuit (24) converts the image data to display signals, and an analog display circuit (28) converts the display signals to drive signals to form a (preferable color) raster display on a CRT (30). A display memory stores the image data and a programmable attribute look-up table stores attribute data. Under the control of the central processor, the image data in the display memory is read out and addresses the attribute look-up table which provides attribute signals as output. A pixel rate converter reads in the attribute signals at a first rate and outputs analog display signals at a much higher second rate, with a video bandwidth of up to 210 MHz. The central processor can also provide intensity control signals to the analog display circuit so that the intensity level of each of the attributes identified by the attribute signals can be varied. The display signals are amplified by a current switching amplifier with a separate channel for each category of pixel, the output being converted to a voltage signal to drive the gun or guns of the CRT. <IMAGE>

IPC: F04B23/06
Filed: 1985-03-25
Abstract: The invention relates to a fluid pumping system wherein a number of pump units (1) are driven by a corresponding number of cams (14) on a common cam shaft (13). In such systems selective actuation of one or more of the units enables an individual pump unit to serve an individual end use, a number of units to be grouped to serve a common end use or all the units to be grouped to serve a single end use. Each unit comprises a piston (41) reciprocable in a respective cylinder (3) by the drive cam (3). Each cylinder has an inlet valve (18) and an outlet valve (37), the flow of fluid to the inlet valve being from an inlet (16) and a passage (15) when a respective fluid- operated valve (25) is open. Fluid pressure is admitted to an associated cylinder (33) containing an actuating piston (34, 30) for the valve (25). All of the fluid-operated valves are connected to a common control means operable to direct fluid to the cylinders of those units which are required to be operated. <IMAGE>

Title: Infra-red altimeter
Inventor: BROWN GEORGE
IPC: G01S11/12
Filed: 1986-09-13
Abstract: The altitude of an aircraft is derived using a modified infrared line scanner adapted to scan regions of terrain below the aircraft alternately in forward and rearward directions. The results of the forward and rearward scans are correlated to determine the time delay between scanning of the same swathe of terrain in forward and rearward directions. This time delay can be used together with the velocity of the aircraft to calculate its altitude.
