Title: Spin control in combination washing and drying machines
Inventor: BAKER SIMON JAMES
IPC: D06F33/68
Filed: 1990-01-05
Abstract: A combined clothes washing, spin drying and tumble drying machine includes two user selectable wash programmes the first of which is selected to end in spin drying and provides a first spinning operation having a sequence of spins at increasing speeds followed by a final high speed spin, and the second of which is selected to end in tumble drying and automatically provides a modified spinning operation consisting of the first spinning operation preceded by an additional sequence of spins over a lower range of speeds. This modified, extended, spinning operation helps to ensure that the clothes are not left clinging to the clothes drum at the end of spinning and that the clothes are evenly dried and uncreased at the end of tumble drying.

Title: Abradable seal coating and method of making the same
Inventor: LITCHFIELD WILLIAM BARRY
IPC: C23C4/18
Filed: 1990-03-23
Abstract: An abradable seal coating on at least one of a pair of members having relative rotational movement comprises a two phase composition consisting of a first phase of a metallic alloy matrix of approximately 88% aluminium and approximately 12% silicon, and a second phase of an organic dispersoid material, the first and second phases being codeposition onto a substrate in the ratio 80:20 respectively. The two phases are modified after codeposition onto the substrate by heat treating at a temperature of 450 DEG C for about sixteen hours. The organic dispersoid material is preferably a polyester powder. The heat treated coating can be used at elevated temperatures and has improved abradability whilst maintaining its integrity.

Title: End fittings for Chromatography Columns
Inventor: SHEPHERD PETER
IPC: G01N30/08
Filed: 1990-11-08
Abstract: The present invention relates to chromatography, and provides in a chromatography column new end fittings and an insert 114. Each end fitting is a plastics plug 74 which is screwed to the end of the column tube 32, and inside the end fitting is a shoulder 115 which is engaged by the insert 114. The insert fits neatly into the column tube so that it can be used to press against the column packing. The insert also embodies a cavity 108 for a frit 36. The end of the insert 114 which projects into the column and seats against the column packing, has a skirt 112 which is flared so that the pressure inside the column will spread the skirt which is of flexible plastics material into sealing contact with the column inner wall forming an effective seal. The insert may be in one piece plastics material component, or it may be in two pieces (Fig. 9A not shown), a plastic piece embodying the skirt and stainless steel piece has the portion which engages the shoulder. Passage 116 through the insert allows eluant supply pipe 16(18) to reach the top of the column, eliminating the ferrule depth. Voids in the column may be reduced by adjustment of the degree of penetration of the insert into the column. <IMAGE>

Title: Electrical surge protector
Inventor: TURNER PAUL
IPC: H02H9/02
Filed: 1991-09-20
Abstract: The protector comprises, for protecting against excess voltage. a transient suppression device 1 and, for protecting against excess current in the absence of excess voltage, a positive temperature coefficient resistor 2 that is mechanically fast with the transient suppression device 1 by an interference or pressure fit, or by being moulded onto the transient suppression device, thereby avoiding utilising a more intimate form of bonding such as soldering or welding and giving good thermal contact between the two so that heat generated by the transient suppression device upon operation is transferred to the positive temperature coefficient resistor and speed of operation of the protector is enhanced. If resistor 2 is of ceramic form it is moulded in a configuration to give a press fit onto device 1, whereas a plastics resistor 2 may be heat crimped around the device 1. The device 1 may be a gas tube or a thyristor. <IMAGE>

Title: Distributed transaction processing
Inventor: MALAIKA SUSAN
IPC: G06F11/14
Filed: 1992-03-02
Abstract: A method and system for distributed transaction processing between first and second transaction processing means in communication with each other employs a client program on the first transaction processing means which calls a server program on the second transaction processing means. A first type of server program call permits only the first transaction processing means to commit resources for both client and server, both programs effectively being part of a single transaction. A second type of program call permits the second transaction processing means to commit resources independently so that the server program runs as part of a separate transaction.

Title: Carbon black incorporation in polymeric material
Inventor: HOLROYD ERIC
IPC: B29C48/67
Filed: 1993-05-20
Abstract: A loose admixture of polymer pellets and carbon black primary aggregate (together with any other desired fillers) is subjected to a first shear and smear action to incorporate the filler(s) into the polymer and subsequently to additional shear and smear actions to deagglomerate and blend the mixture, all of these actions being carried out at temperatures well below the plasticising temperature of the polymer so that smearing of the filler(s) into the polymer is facilitated. Each shear and smear assembly is made of similar hammer and anvil components comprising a milling tool (38 or 39) acting as a hammer by rotating adjacent an array (33) of stationary pegs acting as anvils. The end face of a milling tool (38 or 39) presented to the pegs has oblique surfaces (42) at the downstream ends of its channels and these smear the mixture against the confronting corners of the pegs (34). Two similar incorporating screws (10 and 10A) feed their product to a common deagglomerating screw (12) and the product of this is either pelletised to make a feedstock or supplied to calendaring mills and extruders for further processing of the mixture. <IMAGE>

Title: Light bulb package as a form of instant lampshade
Inventor: COLLINGS ERAINE ELLEN
IPC: F21V17/00
Filed: 1994-06-24
Abstract: The use of light bulb packaging as a form of an instant lampshade, e.g. a corrugated exterior design is made from a heat resistant paper or material 1 which forms the lampshade. The package is held in shape by the use of a paper or material 4 (not shown in the drawing) that prevents the lampshade forming and enables the light bulb to remain protected. In order for the package to become the instant lampshade and replacement bulb, the strip must be removed. This allows the package to form the lampshade whilst allowing the light bulb 3 to be placed into the light bulb socket. <IMAGE>

Title: Fault location in optical communications systems
Inventor: FISHER DAVID ANTHONY
IPC: H04B10/27
Filed: 1994-08-17
Abstract: In a two-way optical transmission system incorporating a passive optical network (PON), fault detection is effected by a time domain reflectometer technique in which the system transmitter generates a pulse sequence having statistical properties equivalent to a continuous random binary sequence. A delayed copy of the sequence is correlated with an echo of the sequence reflected from a fault, the time delay required to effect correlation giving an indication of the fault location. The transmitted pulse sequence forms part of a scrambled data signal: reception of echoes and correlation takes place when no upstream data signal (which is orthogonally scrambled) is received. <IMAGE>
