Patent GB-2140159-A (GB)
Title: Apparatus and methods for coding and storing raster scan images
Inventor: WEST GEOFFREY ALEC WILLIAM
IPC: G01B11/02
Filed: 1984-04-25
Abstract: In automatically checking circuit boards by raster scanning, it is useful to code and store conductor boundaries for later analysis. Coding time can be reduced by storing an identification of a chain of boundary segments in one of two arrays 27 and 28 each time a boundary is detected in a scan line by a camera 10 and circuits 11 to 17, the identification being stored at an address given by a counter 25 or 26 and corresponding to the position of the segment detected. At the same time signals describing the segment are stored in a store 45 at an address related to the identification. When in the next scan line a boundary segment is detected, an address corresponding to its position is used to address the arrays 27 and 28 and if an identification is found, the new segment is stored as part of the chain identified. In order to reduce storage, signals describing segments are not stored in areas of the store 45 allocated to chains but in the next vacant location and a RAM 47 stores links between segments. <IMAGE>

Title: A null-balanced proximity sensor
Inventor: BREWSTER ARTHUR EDWARD
IPC: G01V3/10
Filed: 1984-04-26
Abstract: A null-balanced proximity sensor comprises a flux generating coil (2) and a nearby flux sensing coil (1) placed within the flux field produced by the generating coil so that in the absence of any metallic object in the flux field flux linkages between the two coils are substantially null and so no output appears at the terminals of the sensing coil. Any metallic object (4) introduced into the flux field will unbalance the field and cause an output from the sensing coil. The sensing coil 2 may be wound round a ferrite core (3) and may additionally be screened to eliminate capacitive coupling between the two coils. The two coils may be mounted on a common plate with a rotatable eccentric mounting to adjust their relative positions. Ferromagnetic adjustment elements may be provided for obtaining balance. The sensor may be used in a position sensing arrangement where a member having a coded sequence of magnetic and conductive elements is provided. <IMAGE>

IPC: A01D87/00
Filed: 1984-09-18
Abstract: A lifting mechanism is provided with coupling means (72,74) for hitching the lifting mechanism to the three-point hitch of a tractor or similar vehicle. The lifting mechanism comprises a support (52) and a lifting arm (54) which is pivotally connected to the support. The lifting arm (54) can be pivoted by means of a ram (58).

Title: Orthogonal mode transducer
Inventor: WATSON BARRY KENNETH
IPC: H01P1/161
Filed: 1986-03-27
Abstract: An orthogonal mode transducer for an antenna feed intended for dual polarised operation in at least two different frequency bands includes a primary waveguide (4) and a first coupling section (5) comprising a side-arm waveguide (7,8) coupled to the primary waveguide for coupling signals in the higher of two different frequency bands supported by the primary waveguide and having a predetermined hand of polarisation. A frequency and polarisation selective filter (11,12) is disposed in the primary waveguide, downstream from the side-arm waveguide in the receive direction. The filter reflects signals with the predetermined hand of polarisation in the higher frequency band but will pass orthogonally-polarised signals in the same frequency band and all signals in the lower of the two bands. A second coupling section (6) is similar to the first section, but its side-arm waveguide (13,14) and its filter (16,17) are displaced angularly about the axis of the primary waveguide by 90 DEG  with respect to those of the first section. The second section thereby couples the orthogonally-polarised signals in the higher frequency band. <IMAGE>
