Title: Switched cable television networks.
Inventor: MANN LEONARD GRAHAM
IPC: H04N7/10
Filed: 1991-05-16
Abstract: In a switched cable television network where at least one channel is supplied to a subscriber at a dedicated frequency, the particular channel VHF1-4 being determined by an off-premise switch or converter SW1-4 in response to dynamic subscriber selections, the subscriber is enabled to control the selected channel from any of a plurality of spatially separated locations at his premises. This is done using a single home control unit 10 in association either with infra red receiver/ multiplexer units 15 connected to outlets 1-6 at each of the spatially separated locations (the outlets being connected to the home control unit by a coaxial cable 13), or with a mobile unit which communicates directly with the home control unit at radio frequencies. A plurality of independent selections may be made of channels to be supplied to the subscriber at a plurality of dedicated frequencies, (Figs. 5, 6, not shown), this selection facility also being exercisable at a plurality of spatially separated locations. <IMAGE>

Title: Gutter system
Inventor: DALES FRANCIS DONALD
IPC: E04D13/158
Filed: 1991-07-09
Abstract: A refurbishment gutter system comprising a device 20 secured to a concrete gutter 22. The device 20 comprises a channel portion 24 adapted, in use, to be received within the gutter 22, and an integral wall portion 26 at an opposite side from a part of a building 36 to which the gutter 22 is secured. This wall portion 26 extends around an outer perimeter of an exposed face of the gutter 22. The device 20 therefore encompasses the gutter 22 thus ensuring that rain will fall into the channel portion 24 or be driven against the wall portion 26, and not into the concrete gutter. Water will not, therefore, be able to penetrate the buildings via the concrete gutters. <IMAGE>

Title: Illuminated visual display
Inventor: CALLAGHAN JAMES ROBERT
IPC: G09F9/305
Filed: 1991-11-25
Abstract: The invention relates to an illuminated visual display apparatus wherein an illuminating source directs light to one end of a bundle of fibres and the light is transmitted along the fibres to define a visual display remote from the illuminating source. The ends of the fibres adjacent the illuminating source 16 are clamped together and the other ends of the fibres are supported in spaced apart relationship by a support means, in the same relationship as the clamped ends of the fibres so that a pattern of light shades or colours applied to the clamped fibre ends is reproduced at the spaced apart ends. The support means 14 may be a wire, mesh or perforated means. An element carrying images having different light transmission characteristics, may be positioned between illuminating source and bundle of fibres, and this element may be recessed conveyor belts 18, 19 carrying transparencies in their recess. Cooling air may be introduced between illuminating source and bundle of fibres suitably by means of a rotatable apertured disc (32, Figure 4). <IMAGE>

Title: Communications bus and controller
Inventor: BOAL JOHN HILL
IPC: H04L12/64
Filed: 1992-03-09
Abstract: In the field of data communications, many systems have been developed using a variety of communications modes depending on suitability for given applications. These modes are generally compatible only with specific systems. According to the invention a communications controller (54) is connected to a time division multiplexed bus (52) for controlling the writting of signals to and the reading of signals from the bus. The controller is a state machine switchable between states each corresponding to a mode of communication on the bus. Communication in a first mode, e.g. a packet mode, can be interrupted by communication in a second mode, e.g. a cell mode, which requires more immediate bus access. In addition to at least one information line the bus has an allocate line on which an allocate signal is asserted by the controller on communication in the second mode to inhibit communication in the first mode.

IPC: C09C1/36
Filed: 1992-09-15
Abstract: A method of preparing sunscreens in which a dispersion of zinc oxide particles in an oil is formed by milling in the presence of a particulate grinding medium and mixed with cosmetically acceptable materials is claimed. The particles of zinc oxide have an average size of from 0.005 to 0.15 micron and the dispersion is substantially transparent to visible light but with an extinction coefficient at 308 nm (E(308)) and at 360 nm (E(360)) of at least 9 litres per gram per centimetre. The ratio E(360):E(308) is in the range 0.75:1 to 1.5:1. In a preferred method a mixed dispersion containing titanium dioxide and zinc oxide, having E(308) at least 15 litres per gram per centimetre, E(360) at least 10 litres per gram per centimetre and the ratio E(360):E(308) in the range 0.3:1 to 1.5:1 is used. The mixed dispersion is also claimed.

Patent GB-2262203-A (GB)
Title: Call routing in mobile telephone systems
Inventor: SAWYER FRANCOIS
IPC: H04W8/12
Filed: 1992-11-12
Abstract: A method and apparatus for providing continuous and accurate location information pertaining to a mobile telephone subscriber wherein a temporary location is utilized. Upon entry to a visited system the mobile subscriber either transmits a registration access or a call access. If the mobile subscriber sends a registration access, the visited system acknowledges the registration, records the mobile subscriber's presence and signals the mobile subscriber's home system of the mobile's presence. Receipt of the mobile's location from the visited system causes the mobile subscriber's home system to update its location data for that particular mobile. If the mobile subscriber initiates a call access from within the visited system without registering within the visited system, the visited system allocates a record for the mobile indicating within the record that it has not received a registration from the mobile and transmits to the home system a temporary location signal. The home system, upon receipt of the temporary location stores the location without deleting the existing location data for the mobile subscriber. The temporary location data is deleted upon the conclusion of the mobile subscriber's call from within the visited system. The temporary location data is used by the mobile subscriber's home system to effectuate the routing of calls for the mobile subscriber. <IMAGE>

Title: Apparatus for catching wild animals
Inventor: THURLOW BARRY CHARLES
IPC: A01M23/08
Filed: 1993-09-13
Abstract: Apparatus for catching wild animals such as rabbits includes a fence constructed from a plurality of fence panels 11, 12 each of which has a plurality of vertically-slidable bars which can held in the lifted position. A remotely operable catch mechanism allows all of the bars simultaneously to fall to contact the ground. A cage 10 is provided between two fence panels and has an opening 42 leading to the interior of the cage. The fence is erected with the bars raised, between a safe haven for the rabbits and their feeding ground. Once the rabbits are used to the presence of the fence and are feeding, the bars are allowed to fall and prevent the return of the rabbits to their safe haven. The fence then guides the rabbits into the cage 10 whence they may be collected for disposal. <IMAGE>
