Patent GB-2214978-A (GB)
Title: Fastener and strip mounting
Inventor: JACKSON PETER
IPC: E04F19/02
Filed: 1988-02-08
Abstract: A fastener (10) comprising  - a base portion (11), and - a plurality of resiliently deformable limbs (12) upstanding from the base portion, the outer ends or noses (14) of said limbs being spaced to engage the inner-facing walls (26) of a mounting recess (30) in an element (18) to be fastened thereby, said noses also incorporating bevelled contact surfaces (16), so that engagement with said recess walls (26) laterally deflects the limbs, to allow passage of said limbs as a whole deeper into said recess and thus closer coupling movement of the fastener (10) and said element to be mounted, further relative movement of said fastener and said element allowing said noses to transfer to a laterally wider innermost region of said recess, whereby said limbs can relax to their undeflected condition, but with the undersides of said noses resting in contact with abutment ledges (24) in said recess inner walls, inhibiting withdrawal of said fastener from said recess. Use, particularly, but not exclusively, in the field of mounting decorative wooden strip mouldings in the building, construction, decoration, refurbishment or architectural industry.

Title: Biaxial concrete masonry casting method and apparatus
Inventor: PARDO JORGE
IPC: B28B7/30
Filed: 1989-04-20

Title: Dual-mode video board with parallel-to-serial conversion
Inventor: BAE SHEE-KYU
IPC: G09G5/36
Filed: 1990-02-15
Abstract: A video board in a personal computer supports a 2-gray level monitor as well as a 4-gray level monitor, by serving both 1-bit plane and 2-bit plane video board operation. A video output controller 100, having a shift register 101, a jumper 102 and a divider 103, generates serial video output signals according to a selection made between the 1-bit and the 2-bit plane modes. The shift register 101 receives parallel input data and shifts the data in response to clock pulses CP. In the case of 1-bit plane mode, eight clock pulses CP are supplied between set pulses on an input line S0 connected to a clock generator 70 output line by the jumper 102, while in the case of the 2-bit plane mode, four clock pulses CP are supplied between set pulses on the input line S0 coupled to divider 103 by jumper 102. The period of the pulses from clock generator 70 is divided by two upon passing through divider 103. The selection of the 1- or 2-bit plane mode is made by jumper 102. <IMAGE>

Title: Improvements in and relating to wrappers for foodstuffs
Inventor: GOLDMAN NEIL VERNON HAROLD
IPC: B65D75/28
Filed: 1990-05-15
Abstract: A wrapper for forming a package for a generally triangular foodstuff, e.g. a diagonally cut sandwich, comprises a strip 1 of relatively inflexible sheet material, such as paperboard or card, and a sheet 5 of flexible sheet material, such as a transparent heat sealable plastics sheet material. The strip 1 has a central transverse fold line 2 dividing it into two panels 3, 4 which, in use, extend along the adjacent perpendicular sides of the sandwich. At least panel 3 of the strip 1 is attached to an edge portion of the sheet 5 in the position relative to that edge portion that it will assume in the final package, and sheet 5 is dimensioned so that is will fold around the sandwich and strip 1, with the edge portions of the sheet 5 overlapping the longitudinal edges of the panels 3, 4 of the strip. The strip 1 may be attached to the sheet by adhesive and the overlapping edge portions of the sheet 5 may be heat sealed together. The attachment of the sheet 5 to the strip 1 simplifies the wrapping operation, by avoiding the need to carefully position the sandwich and the strip 1 relative to the sheet 5 before wrapping the foodstuff. The required position of the sandwich on the wrapper is predetermined by the position of the strip on the sheet. <IMAGE>

Title: Method and apparatus for separating synchronising signals from a composite     television signal.
Inventor: PARSONS ROBERT
IPC: H04N5/08
Filed: 1991-06-12

Title: System for pumping fluids from horizontal wells
Inventor: FREET THOMAS G
IPC: E21B43/12
Filed: 1991-10-16
Abstract: Gas is separated from the liquid phase ahead of the pump to avoid slug flow of gas into the pump. This increases the amount of oil that can be pumped from the well by avoiding shutdowns resulting from gas-locking of the pump. A first tube string 22 has an inlet port 25 at its distal end with the upper end being sealingly attached to the lower part of a shroud or housing 16 which encloses a pump 14 and motor 17 which also powers a centrifugal liquid gas separator upstream of the pump. A second tube string 12 connects the earth surface with the pump sealingly through the upper part of the shroud 16. The system is used without a packer in the well. Other embodiments are disclosed wherein the upper part of the shroud is open and wherein the separator is omitted. <IMAGE>

Title: Decreasing the static electrification of nylon
Inventor: BISHOP CHARLES ARTHUR
IPC: D06M10/02
Filed: 1992-04-07
Abstract: A continuous method of modifying the surface static electrification of a nylon filament which comprises exposing the moving filament to a plasma generated in an atmosphere of a gas which is a halogen compound of either hydrogen, carbon or sulphur or a mixture of such halogen compound with another gas, such plasma gas modifying the surface of the filament to such an extent that the normally positive static charge on the surface of the filament is converted into a static charge which has a mean value which is either negative or zero. The plasma gas is derived from carbon tetrafluoride, carbon tetrachloride, hexafluoropropene, hexafluorobenzene or sulphur hexafluoride. It may be used in combination with argon, nitrogen or air. The plasma gas is excited by a microwave generator.

Title: Networks of self-routing optical switches
Inventor: EVERARD JEREMY KENNETH ARTHUR
IPC: H04Q3/52
Filed: 1992-08-24
Abstract: Each Self Routing Optical Switch comprises a non-linear crystal 1, 5, 6, 7 and associated half-mirrors 2, 3, 4, 8, 9, 10, 11, 12, 13, 14, 15, 16. The network consists of arrays of Self Routing Optical Switches connected in layers where each layer has a different set of mirror spacings to enable non ambiguous coding of the destination address. Routing to a particular node is performed by modulating the input light with an autocorrelation function whose period is arranged to coincide with the round trip time delay between the non linear crystal and the Semi-reflecting mirror to which routing is required. A further requirement is that the modulation does not cause ambiguity by having a period equal to a round trip time in a different layer. <IMAGE>

Title: Fluidic powder flow control device
Inventor: MCGUIGAN JOHN ANDREW KENNEDY
IPC: F15C1/16
Filed: 1993-02-04
Abstract: A vortex valve the casing of which has a biconical 6, 7 form with inlet and outlet ports 2, 3 at the apices of the cones and a plurality of control ports 9 in a cylindrical region 8 which joins together the bases of the cones. Mounted within the chamber so formed is a central body 12 the shape of which conforms to that of the inside of the chamber. The valve is used to control the movement of powder from a cyclone separator 31, Fig 3 (not shown) to a collector 34. When control gas is passed through the parts 9, the pressure in the valve builds up to stop the flow of powder therethrough. Also, some of the control gas will pass upwardly against the flow of the powder to clear it from the valve. This avoids caking of the powder or settlement of the powder in the valve. <IMAGE>

Pipes (13.1, 13.2) then transfer the fluid into a further area (7) containing a bailing pipe (9). Leaking fluid is scraped from a centrifugal member (6) by edges, operative in both directions, on the member defining the antechambers. <IMAGE>
