Means for indicating variations in specified data comprises a transmitter controlled by a mechanism which establishes said data and capable of transmitting successive trains of electric pulses each pulse having one of two characteristics the form of each train being governed by the data to be transmitted, wherein said mechanism which establishes said data comprises a series of concentrically arranged rings mounted for rotation about a common axis, each said ring having alternate electrical conductive and non-conductive portions the angular length of each portion of a ring being double the angular length of each portion of an adjacent ring and an associated feeler for each said ring. A signalling system is described for transmitting the height of the tide at each of a number of remote points to a central recording station. At each remote point the tide causes a coded disc, Fig. 3 or Fig. 4, to rotate an extent correspond-. ing to the depth of the tide. The disc is thensensed and the data therefrom is transmitted in serial form to the central station where it is staticized and used to control a graphical recorder. Immediately following the data are sent signals which identify the particular remote station transmitting. Each remote station, when it is transmitting, " locks-out " every other remote station by transmitting, by radio, a lock-out signal. For checking purposes, of which no details are given, each coded disc is backed by a second coded disc arranged to supply signals inverse to those from the main disc. In the Provisional Specification the coded discs are replaced by cams on a shaft, Fig. 1.

Abstract: The audio IF filter circuit described is suitable for use in a television receiver for decoding audio signals transmitted in any of a number of frequency standards. The circuit includes a tuner (1), first and second audio saw filters (2,3), a third audio saw filter (4), a video saw filter (5), and an audio IF demodulator (6). The tuner (1) supplies signals in parallel to the saw filters (2 to 5) and one of the audio filters is activated by control signals (Va to Vc) so as to give a desired filtering frequency depending on the frequency standard in use. The output signal of the activated one of the saw filters is supplied to the demodulator (6). The third audio saw filter is specially adapted so as to have first and second inputs (4a, 4b) which are connected to the tuner (1) by selection circuitry (Q1, D1, D2, L2, R1 to R3) for selecting one or other of the inputs (4a or 4b) in response to one of the control signals (Va). This allows the third audio saw filter to perform the function of two conventional such filters, thereby reducing the manufacturing cost of the filter circuit. <IMAGE>

Title: Colour recognition system for table ball games
Inventor: ENSOR DONALD RIVERS
IPC: A63D15/20
Filed: 1989-12-27
Abstract: A colour recognition system for a coin-operated snooker game has a ball tunnel containing three coloured light emitting diodes (1) arranged at the Brewster angle relative to a photocell (4) which is shielded so as to pick up primarily reflected and polarised light from the ball surface. Three broad spectral channels of light are used for colour sensing. These spectral channels are simply generated without filters or spectral analysis devices (e.g. prisms) by using appropriate light-emitting diodes; conveniently red, yellow and blue. A single broadband photocell is used to detect all channels, flashed on and read out in a predetermined sequence which in practice (and including determinations of dark currents) takes about 15 mS. A microprocessor based controller enables the colour detector to "learn" and distinguish the colours of different sets of snooker ball. <IMAGE>
