Title: Fusion Bonding Optical Fibres
IPC: G02B6/255
Filed: 1980-04-15
Abstract: Optical fibres 1,1' are fused together by applying heat to their ends whilst one fibre 1' is moved towards the other fibre 1 to a position accurately determined by using either a stop 10 or a stepping motor. As shown fibre 1' is moved by a spring 5 between positions defined by stops 9 and 10, the speed of movement of the fibre being controlled by a micrometer head 6 driven by an electric motor 8. If the motor is a stepping motor the stops can be dispensed with, and the motor used to position fibre 1' accurately. Stationary Stands 2, 2' support end portions of the optical fibres 1, 1', and holding stands 3, 3' releasably retain the optical fibers 1, 1'. In use the spring 5 moves the stand 3' under the control of the head 6. Retractible stops 9, 10 are provided to stop the stand 3' at predetermined positions relative to the stand 3. The device also includes a heat source which, together with a reference element 4, the stops 9, 10 and the micrometer head 6, is driven according to a preset sequence such that the end portion of the fiber 1 is successively moved to said predetermined positions and the end portions of the fibres 1, 1' are fusion bonded together. After removal of the bonded fibres, the micrometer head 6 is operable to move the stand 3 in the opposite direction to its initial position as determined by a stop 11. <IMAGE>

Filed: 1980-10-23
Abstract: Known designs of pilger roll have a typical working angle of 180 DEG to 210 DEG  which is divided into three regions; the jaw, the finishing groove, and the delivery zone.

Title: Palletisers and depalletisers
Inventor: VAN DEN BERGH JOHN MAURICE
IPC: B65G59/02
Filed: 1981-12-18
Abstract: The invention relates to a palletiser or depalletiser in which a horizontally- displaceable transfer platform 10 is movable vertically between the level of a conveyor and the upper end of a pallet and is supported on a vertical frame 12 which, together with a gantry 20 is movable up and down a support column 14. The support column is arranged at only one end of the frame 12 which is thus cantilevered, the construction providing improved access to manoeuvre by a fork lift truck to remove a loaded pellet from within the palletiser and to insert empty pallets. Also where removal is via conveyor or by fork lift truck the invention allows the platform 10 to return immediately to its in feed position prior to the removal of the loaded pallet. A modification (Figure 3) includes two spaced frames (12') vertically movable on two support columns disposed on one side of a transfer platform (10') which can selectively build two stacks. The apparatus may operate as a depalletiser. <IMAGE>

Title: Nonvolatile floating gate memory device
Inventor: STEWART ROGER GREEN
IPC: H01L29/788
Filed: 1983-03-08
Abstract: A dual word line, electrically alterable, nonvolatile floating-gate memory cell has a word-line-to- floating gate capacitance (C3) which is significantly greater than either the program-line-to-floating gate capacitance (C2) or the floating-gate- to-substrate capacitance (C1). This allows the program line (46) and the word line (50) to be counter-driven to minimize coupling to the floating gate (42) during the write/erase cycle and to maximise coupling during the read cycle. The net result is higher write/erase/read efficiencies than heretofore possible. <IMAGE>
