Title: Tracking systems
Inventor: STAFFORD RAYMOND
IPC: G01S3/786
Filed: 1989-04-19
Abstract: A method for determining the position of a target within an image of a scene, in which many high contrast items in consecutive scenes are used to determine the most likely target position. The method comprises:- recording successive scene images; 1,2; mapping the positions 5,6 of high contrast items in each new image; eliminating such items 5 not present in both previous images; using information determined from image 1 to predict the likely position of said target within each new image; using said predicted position of the target and the high contrast items shared by the new image and said previous image to construct a co-ordinate system; and, applying said co-ordinate system to high contrast items of said new image in order to locate a position in which the conditions corresponding to said co-ordinate system are best met.

Patent GB-892300-A (GB)
Abstract: 892,300. Dry electrolytic capacitors with oxide films. STANDARD TELEPHONES & CABLES Ltd. Oct. 21, 1960 [Oct. 23, 1959], No. 35985/59. Class 37. In a method of manufacturing an electrolytic capacitor which includes the steps of forming an oxide film upon the surface of an anode body of valve metal, applying a layer of a hydrated manganese oxide upon the oxide film and decomposing the last-mentioned layer to manganese dioxide, the oxide coated anode (which may be of either tantalum or niobium) is first impregnated with a solution of manganese nitrate, either by dipping or under vacuum. The anode body is removed from this solution and impregnated with ammonia solution, which forms the layer of hydrated manganese oxide [MnO(OH)]. The body is then dried and heated to decompose the layer to manganese dioxide. Two further methods, using ammonia gas, are described. Other salts of manganese which will yield the above product after reaction with ammonia are mentioned, and the salts may be dissolved in alcoholic solution.

Title: Offshore aerated sewage station
Inventor: LITTLEJOHNS REGINALD
IPC: C02F3/12
Filed: 1990-09-22
Abstract: Because of the high cost & nuisance factor of building new sewage plants it is proposed that concrete or stool decomposition tanks be placed off shore at the end of sewage outfalls.

Abstract: A fluorescent tube 12 is operated at 15 to 50 kHz by a push-pull inverter 22, 24 and a closed loop control 33, 35, 38 applies an error signal to a program input of a current source 41 whereby the direct current supply to the inverter 22, 24 is varied to maintain the arc current in tube 12 constant. Current source 41 is of linear design with a low differential voltage drop thereacross maintained constant by a switched mode power supply 44 coupled to a 24 volt source 15. Inverter 22, 24 operates at a constant duty cycle of 90 to 95 per cent so that the tube 12 is operated at an arc power of 80 to 90 percent of its rated power and at a substantially constant arc current crest factor of below 1.7 and preferably in the range 1.3 to 1.5. A system control 50 starts the tube 12 by initially enabling a 36 kHz tube filament driving inverter 18, 21 and a strike oscillator 47 for a predetermined period. Control 50 then disables inverter 18, 21 and oscillator 47 and enables the main inverter 22, 24 which at this time is provided with a higher than normal D.C. input from a capacitor C s charged by oscillator 47. If the tube fails to strike the starting sequence is repeated. A circuit 52 applies a shut down signal to inverter 18, 21 and 22, 24 if the tube fails to strike within a predetermined period, corresponding to a predetermined number of strike attempts.

Abstract: The housings of the loudspeaker is divided into two or three chambers V1, V2, V3 by diaphragms M1, M2, M3. One of the inner volumes adjoins the diaphragm of the loudspeaker. Movements of an inner diaphragm M3, caused by pressure changes due to motion of the front diaphragm. are servo supported by an inner electrodynamic transducer TR2, whose diaphragm M2 lies in parallel behind the other inner diaphragm. The supporting movements are caused by a controller, which tries to hold constant the distance between the two inner diaphragms M2, M3. In a further embodiment (Fig 2) the inner diaphragm M3 may be mounted upon the diaphragm M2 of the inner transducer. This arrangement dispenses with the third volume V3. In another proposed embodiment the diaphragm M3 is disposed of and the distance between diaphragms M1, M2 is kept constant. <IMAGE>
