Patent GB-2359143-A (GB)
Title: A liquid crystal device
Inventor: TOWLER MICHAEL JOHN
IPC: G02F1/139
Filed: 2000-10-09
Abstract: A liquid crystal display device includes a layer of a chiral liquid crystal material (3) disposed between first and second substrates (1,1'). An active region (10) of the liquid crystal layer has a thickness-to-pitch ratio (d/p)<SB>A</SB>. The liquid crystal layer also contains a nucleation region (11) in which the thickness-to-pitch ratio of the liquid crystal layer is (d/p)<SB>N</SB> rather than (d/p)<SB>A</SB>. As a result of the difference in thickness-to-pitch ratio of the liquid crystal layer between the active region and the nucleation region, the liquid crystal state that is stable in the active region in the absence of an applied voltage is not the same as the stable state in the nucleation region. In one embodiment of the invention, the thickness-to-pitch ratio of the liquid crystal layer is greater in the nucleation region (11) than in the active region (10). This embodiment can easily be realised in a reflective display device that is provided with a via-hole by using the via-hole as the nucleation region.

Title: Menu item selection
Inventor: GASSLANDER MAGNUS
IPC: G06F3/0489
Filed: 2000-12-27
Abstract: A digital television system having a set-top box controlled by a remote control unit is used to access the Internet. Arrow keys on the remote control unit are used to navigate a focus around irregularly positioned hypertext links on a web page. If a down arrow key is pressed, web browser software determines weighted distances between a link in focus and links below it using an elliptical function. The distances are weighted so as to favour a link closest to being vertically collinear even though other links may be closer.

Title: Method to prevent generation of particles by wall-film peeling
Inventor: KARIYA ATSUSHI
IPC: H01L21/768
Filed: 2001-03-23
Abstract: A method of manufacture of a semiconductor device has a step of forming a film of high melting point metals such as titanium, tungsten, cobalt, nickel or tantalum or nitrides, TiN, WN, TaN, on the surface of a group of semiconductor wafers by bringing the internal temperature of a CVD chamber to a film formation temperature at which the film is deposited, followed by lowering the temperature to a stand-by temperature at a sufficiently slow rate to reduce peeling of metal films on the walls of the chamber. The chamber is held at a stand-by temperature until film formation on the next group of wafers begins. The method prevents the generation of particles deleterious to production of semiconductor devices by wall-film peeling, and reduces dispersion of the thickness of the metal films among wafers.

Title: Pipe threading parachute pig
Inventor: DELAFORCE STEPHEN ROBERT
IPC: G02B6/44
Filed: 2001-04-09
Abstract: A line 66 is threaded between a first access point 24 on a relatively small bore service pipe 14 and a second access point 110 on a main pipe 20, by launching a parachute-like device 62 carrying the line from the first access point and retrieving it at the second access point. A cable, eg an optical fibre, can then be attached to the line 66, and drawn back through to the first access point on the service pipe. The parachute-like device 62 is launched from launch coupling 50, and is held within a parachute housing 60 comprising a flexible guide 63 at its front end which allows the device to be manually lowered into the main pipe via the service pipe. A jet of gas from tube 65 behind the parachute housing separates the housing from the flexible guide and inflates the parachute into the main pipe.
Patent GB-2376476-A (GB)
Title: Toilet seat and lid assembly
Inventor: KEAVENEY ENDA
IPC: A47K13/10
Filed: 2001-06-13
Abstract: A toilet seat (20) and lid (26) are provided, with the lid incorporating a self-closing mechanism. The self-closing mechanism comprises two chambers (36, 37), and when the lid is moved to the opened condition, fluid flows from an upper chamber to a lower chamber, causing the position of the centre of gravity of the lid to change. When a sufficient quantity of fluid has flowed from the upper chamber to the lower chamber, the centre of gravity is such, relative to the pivot axis of the lid, that the lid will close automatically. A damper is provided to damp this movement. In the embodiment described, the fluid flows from the upper chamber to a lower chamber through a flexible tube (38), and when a person is sifting on the toilet seat, the tube is clamped (39) to prevent the flow. Thus the timing mechanism does not operate whilst a person is sitting on the toilet seat.

Title: Shotgun shot, pellets and bullets
Inventor: PHILLIPS ARTHUR HUGH GODFREY
IPC: F42B7/04
Filed: 2002-02-28
Abstract: A shotgun shot, pellet or bullet is made of an alloy containing bismuth, tin and 2% to 5% by weight copper. Preferably the alloy contains less than 50% by weight bismuth. In a preferred embodiment the content by weight is 45% bismuth, 52% tin and 3% copper. The inclusion of the copper in the alloy simplifies the manufacturing process of the shot, pellet or bullet as compared with known bismuth and tin alloys. Shot or pellets may be formed by short or long drop forming and bullets may be formed in conventional bullet moulds. The ballistic performance of shot made from the alloy is good and for bullets from the alloy is comparable with that of copper coated lead bullets.
