Patent GB-2124318-A (GB)
Title: A screw threaded fastener and fastened assembly
Inventor: BETTINI JOHN E
IPC: F16B25/00
Filed: 1983-07-20
Abstract: A screw-threaded fastener 10 for attaching articles 28 of predetermined thicknesses to sheet metal 30, the fastener 10 including a head 12 at one end, a generally cylindrical elongate shank, a tip 22 at the other end, a plurality of discrete threaded sections 26a and 26b on the shank and at least one annular unthreaded shank portions 24 between each pair of the thread sections 26a and 26b. The annular unthreaded shank portion 24 is spaced from the head at a predetermined distance or at predetermined distances which correspond to the predetermined thickness of articles to be fastened. Thus, when the head 12 of the fastener 10 is seated, the fastener is free to rotate without continued advancement with the sheet metal 30 being located at the unthreaded portion 24. Naturally when a plurality of unthreaded portions 24 are included the fastener 10 can accommodate articles of different thickness. The annular portions 24 can be given a greater axial extent to allow the screw to move relative to the panel when the panel is compressed in the vicinity, thereby preventing the screw head from penetrating an overlying membrane. <IMAGE>

Patent GB-2145320-A (GB)
Title: Processing and products of oil palm fruit
Inventor: MORRIS JOHN EDWARD
IPC: A23B7/015
Filed: 1983-08-25
Abstract: Gamma irradiation is employed in the treatment of harvested oil palm fruit bunches to achieve partial sterilization of the fruitlets in order to check natural ripening and thereby limit the increase of free fatty acids in the palm oil, which will be extracted from the pericarp of the fruitlets. This avoids the effect of the usual steam treatment in causing migration of palm oil from the fruitlets into the fibre, thereby increasing the yield of palm oil and making the fibre a valuable by-product, e.g. for use in paper-making. The treatment with gamma irradiation may also improve the loosening of the fruitlets from the fibre and loosen the kernel of the fruit, thus facilitating the production of kernel oil. The bunches may be placed on a conveyor which carries them round a cobalt-60 source in a room or chamber with screened entrance and exit for the conveyor.

Title: Soldering surface mounted devices to flat surfaces
Inventor: STRAUSS RUDOLF SIEGFRIED
IPC: B23K3/06
Filed: 1985-04-01
Abstract: An apparatus for soldering surface mounted devices to flat substrates uses a temperature-resistant hydrocarbon fluid both as a heat- and a solder-transfer medium. The fluid is heated to a temperature above the melting point of the solder, and a suspension of droplets of molten solder is formed in the fluid by mechanical means. Jets of this suspension are directed against the joints to be soldered, surplus solder being removed subsequently by further jets of hot, solder-free fluid, the assembly being fully immersed in the fluid during this procedure. Afterwards, the assembly is removed from the hot fluid, adhering fluid being removed by jets of air and recovered.   By the same principle, circuit boards with plated-through holes can be given a uniform coating of solder, the bores of the holes remaining free of solder.

Title: Improved liquid crystal optical switch with reduced cross talk
Inventor: BOS PHILIP J
IPC: G09G3/36
Filed: 1985-07-02
Abstract: A field sequential color display system (10) employs a liquid crystal device operating as a variable optical retarder (12) which is positioned in front of the screen (40) of a raster scanned cathode ray tube (38) to develop a high quality multicolored image. The liquid crystal device is divided into upper and lower cell segments (34 and 36) to decrease the time between successive color fields. Each cell segment is separately commanded by a switching circuit (46) to a predetermined optical retardation state when the electron beam scans the portion of the screen covered by the cell segment. Each cell segment has two electrode structures (22 and 30; 24 and 32). Electrode structures 22 and 24 are electrically isolated and are connected to the ground potential of the switching circuit to minimize the optical cross talk between cell segments and thereby minimize the spurious transmission of colored light from the display system. <IMAGE>

Patent GB-2192252-A (GB)
Title: Improvements in or relating to braking mechanisms
Inventor: STONES KEVIN
IPC: H02K7/102
Filed: 1987-05-21
Abstract: A brake mechanism for a rotary member comprises a helical spring (3) in frictional engagement with the member so as to be rotatable therewith. One end (5) of the spring (3) extends radially from the spring (3). A stop member (6) is movable into and out of the path of movement of the end (5). When the stop member (6) is clear of the path of movement of the end (5), the spring (3) rotates freely with the member. On movement of the stop member (6) into the path of the end (5), the latter is held against rotation. That causes a few turns of the spring (3) adjacent the end (5) to loosen but the remainder remain in frictional engagement with the member and exert a braking effect thereon. The member may be a shaft (1) or a cup- shaped container with the spring (3) in frictional engagement with the interior wall thereof. The brake mechanism may be employed in a powered tool such as a hedge trimmer or lawn mower. <IMAGE>
