Title: High pressure gland for optical fibres and/or electrical conductors
IPC: H01B17/30
Filed: 1979-08-21
Abstract: A high pressure gland for optical fibres and/or electrical conductors has a tubular member 1 through which the fibres/conductors 2 are loosely passed. The bore of the tube is then filled with an encapsulating plastics material 3 which adheres to both the fibres/conductors and the wall of the tube bore.

Title: Cooling element
IPC: F25D3/00
Filed: 1979-10-25
Abstract: A known cooling element for use in a thermally insulated receptacle employed for the temporary cool storage of containers for beverages and the like, consists of a hollow, substantially box-shaped body provided with a closable filling opening 11 located so that in the normal filling position the body cannot be filled completely with liquid used for providing a cooling medium, and with holes in which the containers to be stored can be placed. However the cold transfer across the surfaces of the holes is limited and thus the cooling elements have to occupy an undesirably large volume of the receptacle. Such cooling elements according to the invention have improved cold transfer by the holes 17, 18 being in the form of apertures extending through the cooling element connected to each other over their full height by a space 19 whose width is less than the diameter of the apertures. In one embodiment of the invention two such apertures are provided on a diagonal of the element, which may be of substantially rectangular form. <IMAGE>

Title: Slats for Cattle Grids or for Solid Flooring
IPC: A01K1/015
Filed: 1979-12-18
Abstract: The two lateral faces 4 of a concrete slat 1 are provided with projecting stubs 6, 7 which are axially staggered so that when the slats are laid parallel to one another, the stubs intercolate and contact the opposing lateral face of an adjacent slat. Each slat is of trapezium section, and each stub end face (9) is reversely sloped to that of the lateral face of the slat so that each adjacent slats support each other when against both lateral and vertical deflection. The slat is especially useful in forming a cattle grid, in which case the slats are laid with their broader sides (2) lying uppermost but, alternatively, they may be laid with their narrower sides (3) uppermost and with the stubs shortened to allow the facing bottom lateral edges of adjacent slats to touch; the surface thus formed then being filled with concrete to form a solid flooring. <IMAGE>

Title: Manufacture of thinned substrate imagers
IPC: H01L21/306
Filed: 1980-07-22
Abstract: The front surface, with at least one imager formed thereon, of a semiconductor wafer and the a peripheral edge of the back surface of the wafer are protected by either coating them or by placing the wafer in a special fixture. The so protected wafer is then placed in a chemical bath and thinned to the desired thickness over the entire center region of the back surface. Then a sheet of glass 20 which fits into the thin region within the unthinned rim on the back surface is glued to the back surface using pressure 22, to provide a laminated structure, e.g. after curing. The pressure, e.g. in vacuo, forces the adhesive outward and removes bubbles and voids before the preferred curing. In the case where more than one imager has been formed on the wafers front surface, individual imager devices are separated from one another by cutting through the glass 20 and thinned substrate along lines between the devices. <IMAGE>

Title: Variable speed electric motor drive system
IPC: H02P27/04
Filed: 1980-08-28
Abstract: The system comprises a variable frequency inverter 10 which is supplied from a constant voltage d.c. source 11 feeds a tuning circuit 13 eg a capacitor in series with the field winding of an induction motor 14. A shaft speed sensor 17 supplies a first drive signal to a torque controller 16 which has a second drive signal supplied by an operator actuated controller 18, these signals being added to provide a control signal on line 12 to set the operational frequency of the inverter 10. The inverter frequency is variable within predetermined maximum and minimum values, the resonant frequency of the field winding circuit is between these values, and the feedback loop operates with positive feedback so that the shaft speed of the motor 14 is variable within limits and the maximum torque/speed characteristic has the form conventionally attributed to an IC engine. Torque controller 16 may incorporate a microprocessor so that the control signal on line 12 can be any desired function of the input signal from sensor 17. <IMAGE>

Title: Strap fastener
IPC: F16L3/233
Filed: 1980-11-10
Abstract: A strap fastener for securing, for example, a bundle of cables or a hose has three parts which may be assembled at the time of fitting the fastener. The three parts are a flexible band (1) which is cut to a required length from a supply of band material in a dispenser, and a band receptacle (4) comprising a fixed member (5) and a screw (6). Since the band can be of variable length, the fastener is suitable for securing articles of widely differing sizes. The screw acts radially relative to the secured article, largely preventing movement of the fastener around the article when it is being fitted. <IMAGE>

Title: Loading a rotary film cartridge
IPC: G03B19/02
Filed: 1981-12-22
Abstract: When a cartridge 2, having an exposure opening 2d and containing a rotary film disc 8 and a film cover 3, is first inserted into the cartridge chamber 1e of a rotary film camera, a stud 4c on a lever 4, which is rotatable about the driving spindle 10 for the film disc 8, causes cartridge 2 to pivot about point 1b against the bias of a spring 6 so that a film support 1a makes minimal contact with film cover 3. When the camera back is then closed, a slider 7 moves to the right from the position shown, thereby causing (a) stud 4a of lever 4 to rotate film cover 3 to the film uncovering position and (b) stud 4c of lever 4 to slide to ramp 2b of cartridge 2 and allow cartridge 2 to pivot back so that film support 1a contacts film disc 8. There is thus minimum interference between film support 1a and film cover 3. <IMAGE>

Patent GB-2095582-A (GB)
Title: Oscillating mechanism for spray nozzle
IPC: A62C31/24
Filed: 1982-03-15
Abstract: In a mechanism to provide automatic traverse oscillation for a fire-fighting monitor 1 means including a clutch is provided for selecting the position of the angle traversed. Water is tapped off from the main supply pipe 9 which feeds the monitor and passed to a Peltonwheel turbine 14 which is connected via a gearbox 17 to a drive wheel 18, to which a crank arm 19 is pinned. The other end of the crank arm 19 is linked to a shaft 21, so that as the wheel 18 is driven to rotate by the turbine the shaft 21 is caused to oscillate. The shaft 21 is engageable through a concentric clutch assembly 22 with a drive gear 23/28 in mesh with a ring gear 24 keyed to the hollow axle 6 by which the monitor head 2 is both supported and fed with water from pipe 9. When the clutch 22 is engaged, therefore, the monitor head 2 is automatically oscillated to traverse its jet through a predetermined arc. The clutch 22 can be disengaged manually by lifting the cover 33 on the top of the assembly, thereby to interrupt the drive from the shaft 21 to the gear 23/28 via an associated socket member 25. The head 2 can then be rotated by hand to a new position and the clutch re-engaged so that the head now oscillates in a new sector of the horizon. Likewise the clutch can be disengaged to permit manual override of the oscillating mechanism at any time. <IMAGE>
