Title: Radar ranging system
Inventor: WHITEHEAD ERIC ARTHUR NORTH
IPC: G01S13/44
Filed: 1982-07-21
Abstract: In an airbourne ground-ranging monopulse radar system the sum (S), azimuth difference (A) and elevation difference (E) signals derived from a plurality of statistically-independent radar returns are analysed to obtain an estimate of the orientation of an iso-probability-density surface defining (with respect to corresponding coordinate axes) S, A and E amplitude combinations of a particular probability density. The orientation of this iso-probability surface indicates the target elevation off boresight, and is independent of any across-track ground slope. In a practical embodiment (fig. 8) the two difference signals are first split into separate in-phase and quadrature components A', A", E', E" relative to the sum signal S. Variances and co-variances of these four components and S are then derived (10 - 15), and an appropriate function thereof computed (16 - 22). <IMAGE>

Title: Method of measuring thermal neutron characteristics
Inventor: JOHNSTONE CHARLES W
IPC: G01V5/10
Filed: 1982-10-08
Abstract: The thermal neutron decay characteristics of an earth formation are measured by detecting indications of the thermal neutron concentration in the formation during first and second measurement intervals following irradiation of the formation with a burst of fast neutrons. These measurement intervals may be selected from a sequence of discrete time gates which begins following a predetermined time delay after the preceding neutron burst and extends over substantially the remainder of the interval between neutron bursts. The particular set of two measurement intervals used is selected from among a number of possible sets as a function of a previously measured value of the decay characteristic. Measurements of detected radiation, averaged over a plurality of first intervals following respective neutron bursts, and averaged over a greater plurality of second intervals, are used to provide a background-compensated measure of the average level of induced radiation. <IMAGE>

Title: Video processing systems
Inventor: TAYLOR RICHARD JOHN
IPC: H04N5/262
Filed: 1983-03-11
Abstract: A processing system includes a processor 10 and frame store 11. Both the frame store and processor are under the control of address mechanism 12. An incoming pixel is processed with previously stored information and the proportion of processed information restored is controlled to prevent errors in picture information density as store location may be accessed a number of times in a frame period. The addressing mechanism 12 can generate the desired information from address information which is only provided on some of the store locations and which is only updated over more than one frame period. The mechanism includes spatial and temporal interpolators to effect this operation. <IMAGE>

Title: A workpiece transfer device
Inventor: STEVENSON CHRISTOPHER T S
IPC: B29C65/78
Filed: 1983-05-13
Abstract: Workpieces (W), which may have irregular and inconsistent outer peripheries, are located by a pin (15) and a block (16). Pairs of gripping jaws (22) engage a workpiece (W) without altering its orientation, and are locked in position by a clamping action exerted by two support members (20, 23) under the action of a hydraulic cylinder and piston unit (26).

Title: Phosphonic oil palm fruit bunch ripening and loosening method
Inventor: SANG CHIN PING
IPC: A23B7/16
Filed: 1984-03-20
Abstract: Certain described phosphonic acid derivatives, particularly 2-chloroethyl phosphonic acid, applied either by painting on to the cut surface of the peduncle of the oil palm bunch soon after harvest or as a post harvest spray on the whole bunch, accelerate the rate of ripening of the individual oil palm (Elaeis guineensis) fruits.

Title: A bi-polar adaptor for multi-polar armoured electric lines forming part of installations for the illumination of interiors
Inventor: ZUCCHINI GUIDO
IPC: H01R25/14
Filed: 1984-04-30
Abstract: The adaptor 12 comprises a first casing 51 which is a sliding-fit into a length of channelling 2 of inverted U cross section carrying internally two sets 7a, 7b of electrical conductors facing each other. Integral with the casing 51 is a second casing 52 which remains outside the channel 2 and is for connection to an illumination unit. Three contacts 16, 17, 18 project from the same side of the casing 51 and are operated so as to be moved towards the conductors 7a, 7b by cams 25 and 26 of a control shaft 24 which is free to move vertically and is arranged at right angles to the contacts. The cam 25 permanently engages the contact 16 but one of two cams 26 selectively engages the contact 17 or 18 according to the selected position of the shaft 24. Means for operating the control shaft and locking the adaptor structure to the channelling include a knob control grip 22 provided with a blind hole in which one end of the control shaft is rigidly inserted. The grip controls the projection of the contacts, and is provided peripherally with a recess (34), Fig. 4 (not shown), into which by a sliding fit a retention pin (35) enters. The pin is connected to a push-button 36 which can be moved vertically against the pressure of a spring 38. The contacts 17, 18, 19 are arranged in axial alignment and co-operate with right-angle flanged plates 30, 33 forming terminals for clamping electric cables connected to the illumination unit and inserted into adaptor through the second casing 52. Locking of the adaptor to the channel 2 is by a rotating latch 20 moved by the grip 22. <IMAGE>

Title: Artificial leg
Inventor: WOOLNOUGH VICTOR
IPC: A61F2/64
Filed: 1985-10-29
Abstract: An artificial leg having a covering which is discontinuous in the region of the knee has a thigh component (16) with an end portion comprising a two-part knee ball (14) and an endoskeletal shin component (12) coupled to a knee joint inside the knee ball (14). The internal structural member (12A) of the shin component passes through an anterior-posterior slot between side portions (14A, 14B) of knee ball (14) to allow unobstructed flexion of the limb. The upper part of the shin is surrounded by a rigid shell (22) having an anterior upward extension (22A) which covers the slot when the limb is fully extended or partially flexed. At full flexion, that part of the slot which is no longer covered by the shin extension (22A) is closed by a flap (26) which is connected by an integral hinge to the knee ball (14) at the end of the slot. This flap (26) hinges outwardly behind the shin extension (27A) as the joint is extended to allow the internal member (12A) to reach the end of the slot. Instead of being hinged, the flap may be slidably mounted in either of the components of the limb. <IMAGE>
