Title: Three-dimensional maximum a posteriori (map) tracking
Inventor: LO ALLEN K
IPC: G01S7/527
Filed: 1993-03-11
Abstract: An automatic detection apparatus and method applies the Short and Toomey algorithmic processing procedure to a frequency and beam direction windowed and time segmented set of FFT magnitude detected data, comprising time, frequency and beam direction data, to determine the presence or absence of narrowband lines indicative of target tracks. This is achieved by storing the time, frequency and beam direction data, and then processing (32, 33) this data using a predetermined three-dimensional maximum a posteriori procedure whereby individual target tracks associated with each beam direction are concurrently processed, and whereby transitions are made between adjacent beam directions in order to process target tracks having a maximum signal to noise ratio to provide for detection of a target. An output target track is generated by combining the high signal to noise ratio portions of the processed individual target tracks into a single output target track. The present invention extends the tracking capabilities that are obtained using the Short and Toomey processing procedure from two dimensions to three dimensions, and this added dimension provides spatial tracking in addition to spectral tracking. The spatial tracking is performed concurrently with the spectral tracking in an array processor. <IMAGE>

IPC: B07B1/46
Filed: 1995-02-28
Abstract: A sifting screen is described comprising a rigid frame, a first woven cloth (10,14) of hard wearing metal wire, stretched thereacross and secured thereto, and a second woven cloth (12, 16) having a coarser mesh than the first cloth (10,14) and being woven from an elongate material of greater cross section than the first, also stretched across the frame, and secured thereto, below the first cloth (10, 14), to support the latter against sagging. In accordance with the invention, at least the wearing surface of the material from which the lower cloth (12, 16) is woven is selected to be significantly less hard wearing than that from which the upper cloth (10, 14) is woven, so that wear due to rubbing and vibration during use occurs to a greater extent in the lower cloth than in the upper cloth. In one example, the upper cloth is woven from stainless steel wire and the lower from phosphor bronze wire. In another example, the lower cloth is of wire (18, 20, 22) having a coating (19, 21, 23) of an epoxy based material, or Teflon<TM>, or Molybdenum Disulphide. In another example, the lower cloth is formed from a plastics material or Kevlar<TM> or carbon fibre.

Patent GB-2312861-A (GB)
Title: Valves in continuous casting
Inventor: WHITTINGTON KEITH RICHARD
IPC: B22D41/14
Filed: 1996-05-08
Abstract: In the continuous casting of steel the liquid, molten, metal is poured under gravity from a reservoir container known as a tundish through a tube into an open-bottomed, water-cooled mould from which a solidifying strand of steel is withdrawn continuously. Accurate control of the pouring is traditionally accomplished by hydraulic manipulation either of a slide gate fitting across the pouring tube or of a conical ceramic stopper in the tundish outlet, but these devices are subject to blockage and erosion, to freezing up of the apertures through which the melt passes, to leakage, and to wear, all of which make accurate control difficult and necessitate frequent replacement of the moving parts. Ideally, a control valve for this sort of use should have no moving parts, be capable of rapid and continuously variable flow rate adjustment, be usable with standard pouring tubes, and should be small and light. The present invention proposes a form of electromagnetic valve which substantially or wholly meets the desired criteria. More specifically there is to be created across or around the outlet/pouring tube (channel) of the molten metal reservoir ( the tundish, for example) an alternating electromagnetic field, that there be induced electrical currents - eddy currents - in the molten metal as it passes through this field, which eddy currents interact, directly or indirectly, with the applied magnetic field, and that the directions and magnitudes of the field and of the induced eddy currents are arranged such that forces are generated in the molten metal which oppose the downward flow of the liquid and so provide the desired controllability of the passage of the metal through the outlet. The channel may have a reducing cross-section or alternatively there may be two magnetic field generators.

Title: Gripping device
Inventor: HEAP DAVID WILLIAM
IPC: B65B21/12
Filed: 1996-11-01
Abstract: The invention relates to a device (10) for gripping an object such as a bottle, and also to a bottle-handling machine (40, Fig.4) incorporating the device. The device includes a body portion (13) which is for mounting in a bottle-handling machine and has extending therefrom first (22) and second (23) arms for gripping the object.

Title: Entertainment machine
Inventor: LEWIS JEFFREY
IPC: G07F17/34
Filed: 1996-11-05
Abstract: A coin-operated entertainment machine has a movable symbol display which may be defined by side-by-side rotatable reels (1, 2, 3) bearing symbols (8) around their peripheries. The reels are rotated and are brought to rest by operation of stop buttons (11, 12, 13), one beneath each reel. The reels stop at positions determined by the operation of the stop buttons influenced by a control system (17) of the machine. The control system (17) makes stopping decisions with reference to a table of information relating to the available stopping positions. This table is calculated dynamically by the control system (17) while the reels (1, 2, 3) are rotating.
