Title: Optical fibre splice
Inventor: DALY MICHAEL JOSEPH
IPC: G02B6/38
Filed: 1984-12-07
Abstract: In an improved method of effecting end-to-end joints between optical fibres 4 of two optical fibre ribbons 3, the optical fibres of each ribbon are separated over an end part of the ribbon and are introduced into longitudinally extending, parallel grooves transversely spaced in a surface of one of two elongate support members 1, the transverse spacing and cross-sectional shapes of the grooves in one member being identical to those of the other member. A coating 5 of hardenable material is applied over the surface of each member and over the optical fibres 4 supported in the grooves to bond the fibres in the grooves. Each elongate member 1 is cut and polished so that end faces of the optical fibres 4 and an end face of the elongate member lie in the common plane which is normal to the axes of the fibres. The members 1 are then maintained in alignment by a clip 7 with the end face of one member abutting that of the other and with the abutting optical fibres 4 supported on the two elongate members in axial alignment. <IMAGE>

Title: Optical switching arrangement
Inventor: COLLINGS NEIL
IPC: H04Q3/52
Filed: 1986-12-18
Abstract: An optical switching arrangement includes a first optical fibre bundle 3 from which a multiple light beam is directed via a lens system 4 on to an array 5 of multiple quantum well (MQW) devices. After passing through the array the beam is focussed by another lens system 6 on to an output fibre bundle 7. The array allows switching between the beam's input configuration and a desired output configuration. The MQW devices are operable in a detection mode, whereby a desired re-configuration pattern is input optically over one of the fibres and the detected interference pattern that results (which can form a hologram) is conveyed over electrical connections from each device to an electronic store. When switching is required the pattern is recalled and applied as modulation to the devices. The devices may use the self-electro-optic effect or a variant comprising stacked, alternate p-type and n-type layers. <IMAGE>

Patent GB-2244759-A (GB)
Title: Door closing device
Inventor: BROWN PETER EDWARD
IPC: E05F3/10
Filed: 1990-05-17
Abstract: A door-closer comprises a piston 14 connected by a rod 16 with a cam mechanism 17 to 22 for converting reciprocation of the piston to rotary motion of a door-pivoting shaft 11. At one end, the rod 16 has a valve element 33 which is normally urged onto a seat 34 in the piston by the retain spring 13. If an unusually high pressure is established at one side 26 of the piston, for example by unusually rapid closing movement of an associated door, the pressure can prevent the piston moving with the valve element 33 and the rod so that the passage 32 through the piston is opened to relieve the pressure. Alternatively (Fig. 3, not shown) the piston is connected directly to carrier 17, and piston rod 16 extends to a spring abutting nut at the opposite closer end, the nut being adjustable from outside the closer to adjust spring tension and thus the pressure at which valve 34 lifts. The spring abutment on the closer housing may also be adjustable. <IMAGE>

Title: Apparatus for handling bags of granular material
Inventor: YOUNG THOMAS
IPC: B65G59/06
Filed: 1990-10-19
Abstract: Apparatus for handling bags of granular material comprises a pallet magazine 2 for a stack of empty pallets 21 which are fed by a pallet transfer means to a waiting station 10 and from there to a palletiser 12 to which bags 15 of granular fertilizer material are delivered for palletising. Empty pallets 21 are loaded into the pallet magazine 2 by a grab mechanism 6 comprising a pair of grab arms (30, Fig. 2). To transfer a pallet from the pallet magazine 2 to the waiting station 10, ram- driven risers 50 are first extended to raise the bank of pallets. A ram-driven clamp 52 is extended to engage the pallet above the lowermost pallet 21 and clamp it in a raised position. The risers 50 are then retracted allowing the lowermost pallet 21 to fall onto a conveyor (55, Fig. 8b), which delivers the pallet 21 to the waiting station 10. The palletised bags are finally shrinkwrapped. The grab mechanism picks up empty pallets from a robot trolley 4. The provision of the waiting station, which can be pallet-fed by hand, avoids shut down in the event of difficulties with the pallet magazine. <IMAGE>
