Patent GB-2040351-A (GB)
Title: A catch for a flap
IPC: E05B47/00
Filed: 1980-01-25
Abstract: A catch for a spring loaded hinged lid of a Jack-in-the-box consists of lever, one end of which obstructs an inclined lip on the edge of the lid opposite the hinge. The other end of the lever is held by magnetic attraction to a ferromagnetic plate which is fixed with respect to the box. In the vicinity of the magnet is an electrical solenoid which when pulsed by charge stored in a capacitor produces a magnetic field which opposes the field of the permanent magnet and releases the lever. This in turn releases the lid. When the solenoid is pushed the magnet momentarily releases the plate. Once separated the force of attraction is no longer sufficient to overcome the force exerted on the other end of the lever by the lid spring via the inclined lip.

Patent GB-2045515-A (GB)
Title: Improvements in or relating to the control of laser devices
IPC: H01S3/134
Filed: 1980-02-27
Abstract: A control device for a segmented anode gas discharge laser senses the onset of arcing in a region of the anode, switches off that portion of the anode and reenergises it when the arcing has ceased. As shown, the segmented anode comprises groups 3 of individual electrodes 4, each group being associated with an inductor atomic 6, a bi-stable switch 7 and a capacitor 8. When arcing occurs at a particular electrode group 3, the increased current flowing through the associated inductor causes the corresponding bi-stable 7 to be switched ON. The electrode group is thereby shunted by the capacitor 8 which charges up until a threshold voltage is reached, at which the discharge re-strikes and the bi-stable 7 is switched off. <IMAGE>

Title: Rotary screen for refuse sizing
IPC: B07B1/22
Filed: 1980-03-07
Abstract: In a rotary screen (1) for refuse sizing longitudinal lands (4) defining the screen apertures (3) extend radially outward of the screen such that the land width, as measured over the radially outer surface of the lands, exceeds the circumferential width of the apertures. A ratio of effective land width to aperture width of at least 1.2:1 has been found to reduce the tendency for the apertures to become blocked by long flexible items wrapped around the lands. Conveniently the lands have smoothly arched outer surfaces. To assist in clearing any items which may still become wrapped around the land, stiff rubber plates (6) are provided to brush against the screen as it rotates. <IMAGE>
Patent GB-2047942-A (GB)
Title: Record Handling Mechanism for Caddy Type Record Disc Player
IPC: G11B23/03
Filed: 1980-04-01
Abstract: The player plays discs loaded therein in a record caddy, including a sleeve 26 or 152 and a record retaining spine removably located in the sleeve. Disposed on the spine are latches 50, 52 (Fig. 3) or 164, 166 (Fig. 12), for releasably locking the caspine to the sleeve. Latch defeat fingers 100, 102 (Figs. 7, 9) in the player become wedged between the respective spine latches and interior portions of the sleeve of the caddy, during a caddy arrival at a fully inserted position in the player, so that the spine latches are deflected in a manner freeing the spine from the sleeve. The latch defeat fingers carry extensions 112, 114 which engage with hooks 70, 72 on the spine latches to lock the spine to the player when the caddy is fully inserted into the player, whereby the spine, freed from the sleeve and secured to the player, is removed from the sleeve and retained in the player resting on a platform 34 along with an associated record 32 on a turntable during subsequent unoccupied sleeve withdrawal. Resilience of latches 50, 52 causes the fingers 100, 102 to move to a deflected position (Fig. 10) on such sleeve withdrawal, so that when the empty sleeve is reinserted it deflects fingers 100, 102 further (Fig. 11), thus releasing extensions 112, 114 from hooks 70, 72 so that latches 50, 52 again lock the spine and record to the sleeve for withdrawal therewith from the player. A second embodiment (Figs. 12 to 19) has latch defeat fingers 200, 210 separate from spine grippers 234, 236 and linked thereto by levers 252, 254, whereby when fingers 208, 210 are deflected on reinsertion of an empty sleeve into a record-containing player, grippers 234, 236 are moved via levers 252, 254 out of engagement with the spine. <IMAGE>

Title: Yarn detectors
IPC: B65H63/028
Filed: 1980-04-02
Abstract: Changes in yarn tension are monitored, particularly in the context of multiple yarn feed from a creel to a tufting machine, so that warning can be given of a fault condition such as a broken or tight yarn end.   For each yarn end there is a respective yarn tension detector (33) which may comprise a pivotally mounted wire frame (11) with opposite guide formations (14, 15) around which the yarn (13) runs. A fault condition causes the frame to pivot away from a central position to one of two limit positions at which an electric signal is produced by closure of electrical contacts (11, 16, 17). The signal is fed to a remote electronic system which produces a remote visual indication, such as a digital read-out which identifies the location of the fault condition in the creel. <IMAGE>

Title: Resilient Coupling
IPC: F16D3/10
Filed: 1980-12-19
Abstract: A device for the adjusting fuel injection time in diesel engines comprises a rotary driving flange 7, centrifugal bodies and an adjusting member 14. Each centrifugal body comprises two side-by-side members 1, 2; 3, 4 pivotable on bearing pins 5; 6 mounted in the flange 7 and secured to a casing 29. Spaced from the bearing pins 5; 6 the pairs of centrifugal members have pins 9; 8 carrying sliding blocks 11; 10 (or rollers which engage grooves 13; 12 in the adjusting member 14. Rotation causes the centrifugal members 1, 2; 3, 4 to pivot outwards to displace the blocks 11, 10, causing relative angular displacement between the adjusting member 14 and the flange 7 to adjust the fuel injection time. Centrifugal displacement is limited by springs 19, 20; 21, 22 which at one end abut resilient abutments 15; 16 on the adjusting member 14 and at the other end engage resilient abutments 17; 18 anchored in the centrifugal members 3, 4; 1, 2. The spring force acts in the plane of the centre of gravity of the total mass of the pair of centrifugal members extending transversely of the axis of the device. <IMAGE>
