Patent GB-2314441-A (GB)
Title: Wireless remote car alarm
Inventor: WILLIAMS GREGORY VAUGHAN
IPC: B60R25/102
Filed: 1996-06-20
Abstract: The alarm employs a radio transmitter, receiver and additional circuitry. The transmitter is fitted inside the car and is housed either in the rear view mirror, (Fig 3) or a separate module which may be located anywhere around the window glass. The receiver is fitted within the car owner's house and sounds when the transmitter is activated. (By opening a door, or by a sudden impact to the vehicle.) There is no delay time when the car door is opened,thus giving instant warning of intrusion or damage to the vehicle. When the receiver detects a signal from the transmitter it turns on a siren which can only be disarmed from within the house. A dry battery can power the transmitter, thereby making it independant of the car's battery. The receiver is battery powered, and is left in permanent standby for reception of a signal.

Title: Trailer park brake system
Inventor: POWNALL COLIN
IPC: B60T13/38
Filed: 1996-10-30
Abstract: Spring-actuated, air pressure released trailer park brakes 8 are held released by air from cylinder 1 passing via lines A and B when piston 11 of a park valve 4 is manually depressed against bias of spring 13 and held depressed by application of pressure at port 17 from a tractor unit via an emergency or "red " line C. When the pressure in the emergency line is released (e.g. when the trailer is uncoupled) the red button is ejected under spring pressure, air is vented from line B, and the park brakes are applied automatically. In an alternative arrangement, the park valve (36, Figure 5) is biased to the brake applied condition by air under the control of a pilot relay valve (30) operated in response to air pressure in line C or at point P2.
Patent GB-2319120-A (GB)
Title: Ladder
Inventor: HASSALL ANTHONY GEORGE
IPC: E06C7/08
Filed: 1996-11-07
Abstract: A ladder, eg a cable ladder (2), includes a pair of elongate side walls (6,8) and a plurality of spaced apart elongate rungs (10,12,14) extending between the two side walls, each end of each rung having at least one ear (20,22) passing through a respective aperture in one of the side walls and being attached to the opposite side of the side wall to the rung. In this way, the separate components (i.e. rungs and side walls) of a ladder may be fabricated and galvanised separately and the complete ladder then assembled. Thus the galvanised process may be easier to do and the ladders cheaper to make. Furthermore, there may be a saving on storage space when stocking separate piece parts.

Title: Elevator shuttle system
Inventor: SPANER MICHAEL A
IPC: B66B7/00
Filed: 1997-11-13
Abstract: A multi-hoistway shuttle system in which elevator cabs (A, B, C, D, E) are transported between levels. A plurality of hoistways are arranged adjacent one another and overlap, except the upper and lower hoistways. The cabs (A, B, C, D, E) are loaded at a first level into elevator cars, each of which has a plurality of decks and travels vertically in a hoistway. At the top or bottom of each hoistway a car which has reached the top of a lower hoistway and a car which has reached the bottom of an adjacent upper hoistway are situated side by side. The cabs are exchanged by moving them horizontally into the adjacent car. The car containing the new cab is then transported vertically and the cab inside the car continues its journey up or down until the desired level is reached. In the system described there are N cabs for each hoistway plus N for each level, 2N landings at each level and 3N decks on each car. This system allows more efficient transport of passengers while requiring less hoistways and therefore less space in a building.

Patent GB-2334884-A (GB)
Title: Collapsible furniture
Inventor: BRETT MARK TIMOTHY
IPC: D06F81/02
Filed: 1998-03-03
Abstract: Collapsible furniture, eg a seat, chair or ironing board, has a pair of leg assemblies 19,26 pivoted on a common axis 4. Collapsing is achieved by rotation of the mechanism at axis 4, with one leg assembly 19 being held stationary in relation to the rotation of the mechanism. The erect form is achieved when a pushing bar 5 mounted on the mechanism housing contacts one leg assembly 19 thereby preventing any further rotation in that direction, whilst simultaneously a latch 7 is engaged to prevent counter rotation of the mechanism housing and thereby structurally bracing the mechanism. The latch 7 can be released by bar 28 to allow the mechanism housing to counter rotate and therefore reconfigure the collapsed form.

Title: Pruned and non-pruned radial interpolation for colour space conversion
Inventor: VONDRAN JR GARY L
IPC: G06T3/40
Filed: 1998-12-08
Abstract: A radial interpolation technique (FIG. 7-8) accomplishes an interpolation by generating successive sub-cubes (FIG. 6a-6e). A value of a vertex of the final sub-cube generated is used as the result of the interpolation. Sub-cubes (FIG. 6a-6e) are generated by averaging (FIG. 5) a selected vertex value with the vertex values of each of the remaining vertices. A pruned radial interpolation technique (FIG. 9-12, FIG. 38-39) employs a subset of the vertex values of the initially selected cube to generate the result of the interpolation, thereby improving upon the efficiency of the radial interpolation. Non-symmetric pruned radial (FIG. 25-28, FIG. 43-44) interpolation permits interpolation using interpolation data values distributed throughout the color space with a resolution that varies according to characteristics of the color space.

Title: Flame flicker simulation
Inventor: DAVIDSON JAMES KEMBAL
IPC: H05B39/09
Filed: 1999-03-02
Abstract: A filament bulb 1 is driven by a circuit having oscillators 4 which are asynchronous with respect to one another to simulate the random flicker, colour and luminance of a candle or other small flame. The outputs of the oscillators 4 are summed 3 to provide a signal which is applied to a control terminal of an integrated circuit voltage regulator 2 which supplies the lamp 1. The oscillators 4 produce square waves with different frequencies between 1Hz and 3Hz. Summing of the oscillator outputs produces a waveform with additional frequencies which are the sum and difference of the oscillator frequencies. The additional frequencies in the range 0.1Hz to 0.5Hz determine the cycle length of the flicker pattern and the duration of periods of inactivity when the simulated flame appears to be static. Other additional frequencies provide rapid changes in luminance characteristic of a small flame. Flasher circuits built into light emitting diodes may be used as the oscillators 4 (the light emitting function of the diodes not being relevant to the circuit). The drive circuit has short-circuit, current limitation and thermal shutdown protection, and also has means to protect the lamp 4 from damage by initial power surges.
