Patent GB-2031184-A (GB)
Title: A device for positioning a part under viewing apparatus
IPC: H05K13/00
Filed: 1979-09-17
Abstract: A small object e.g. a printed circuit as seen through viewing apparatus is to be moved by a positioning device so that it occupies a desired position and orientation. During movement the object (5) is lifted clear of a support (3) by a retractible rod (10). In previous devices the rod has been rotatable about its own axis. This makes it difficult to match the position of the object with a reference position since the axis of rotation of the object as viewed is displaced by translation of the object. This is overcome by mounting the means for translating the rod (15, 16, 17, 18, 19) on a turntable 11 arranged to rotate about a vertical axis which is unaffected by the means for translating the rod. <IMAGE>
Patent GB-2036856-A (GB)
Title: Gate Operating Apparatus
IPC: E05F15/00
Filed: 1979-09-21
Abstract: The invention concerns apparatus for opening and closing gates comprising a drive means driven by an electric motor (8) and which is connected to a crank (19) on the gate wings (1, 2) by longitudinally resilient connecting links (18) which absorb the movement of the drive means in the event that either of the gate wings strikes an obstacle. The drive means is preferably a rotatably heart-shaped cam (13) which moves a cam follower (15) connected to the connecting links. The invention also provides actuator means (30), which may comprise spring-loaded pads or a hydraulic tube, which are operable by a vehicle approaching the gates to set the drive means in motion. The gates are kept in the closed position by a latch (80) which is automatically released when the drive means is set in motion. <IMAGE>
Patent GB-2037082-A (GB)
Title: Bellows-operated devices
IPC: H01H35/32
Filed: 1978-12-01
Abstract: Bellows-operated device wherein a pressure to be controlled is applied to the interior of the bellows (30) which operates indirectly a push rod (34) which in turn may operate an electrical switch. In order to render the device fail-safe, the bellows (30) is secured to a pressure pad (32) which contacts a flexible diaphragm (37). The bellows (30) is mounted in a housing (35) which is sealed by the diaphragm (37) which has a larger effective area than the bellows. Leakage of the bellows into the space there-around increases the overall pressure on the diaphragm which therefore tends to operate the push rod (34) to simulate an increase in the pressure being controlled. <IMAGE>

Title: Measuring scatter distribution
IPC: G01N21/47
Filed: 1980-01-02
Abstract: In an apparatus in which particles which may include biological cells are passed through an optical sensing zone to measure the spatial distribution of radiant energy scattered from them, a structure and method are provided for increasing the angle of capture of the scattered radiation for a planar assembly of photovoltaic detectors (60). A flow cell (26) is situated at the principal focus of an ellipsoid (29), paraboloid, hyperboloid or similar reflector which is symmetrical about its optical axis (20), along which a light beam is directed. The reflector is utilized to capture the radiant energy on angles which could include most forward and/or backward angles and all azimuthal angles and to deviate the same to the detector assembly (60). By moving the assembly of detectors along the optical axis (20) the optimum distance is established for obtaining the greatest amount of information. <IMAGE>
