Title: Data extraction particularly data extraction for radar stations
IPC: G01S7/292
Filed: 1971-06-29
Abstract: 1349957 Pulse radar THOMSON-CSF VISUALISATION ET TRAITEMENT DES INFORMATIONS 29 June 1971 [9 July 1970] 30348/71 Heading H4D A pulse radar comprises means for defining a tracking window as a selected series of range quanta and a selected series of repetition periods, means for defining an integration window as a specific number of repetition periods at a particular range quantum, means for integrating received radar signals over the integration window preceding each range quantum in said tracking window, and means for determining which integral provides the maximum signal and for determining the range and azimuth thereof. Encoder (2, Fig. 2, not shown) quantizes the matched filter (1) output in time and amplitude. The coded output is detected by analyser (4) which enables either "clear zone" of "noisy" extraction units (11, 12) depending on the clutter density. The extracted data is fed to computer (13) which predicts the target trajectory and sets the tracking gates accordingly. The "noisy" extraction unit is shown in Fig. 4. Video signals 15 are amplitude coded into four bits and fed into register 17 comprising four parallel stages one for each digit. Each stage comprises eight series-connected, thirtytwo element shift registers wherein each element represents a range increment and each register a complete tracking period. The signals are integrated over eight tracking periods by forming the sum where αij = signal amplitude at range i during tracking period j. #ij is stored in register 21 comprising seven parallel stages of thrity-two elements. The maximum integrated signal strength at each range increment is determined by a chain including comparator 22 which provides a logical "1" output if the new integrated amplitude is greater than the previous maximum. This enable gate 23 allowing the new maximum amplitude to be entered in register 25, identical to register 21. If the new signal is less than the previous maximum, gate 26 is enabled allowing the old maximum to be reentered. The maximum signals are themselves compared to determine the overall maximum signal which indicates the wanted target. This is accomplished in a second chain similar to the first. When a new overall maximum is detected, gate 34 is enabled allowing the counter 35 representing the target range to be read into register 45. The target azimuth is found by this detection also enabling gate 44 enabling the number stored in register 39 which represents the azimuth of that integrated signal under consideration, to pass to register 46. Thus at the end of each eight repetition periods the registers 45, 46 indicate the target co-ordinates to the tracking computer.

Patent GB-306453-A (GB)
IPC: C09F5/06
Abstract: 306,453. Scheiber, J. Feb. 20, 1928, [Convention date]. Carboxylic acids; esters. - Paint oils of improved drying capacity are obtained by subjecting mixtures of fatty acids from good drying oils such as wood oil, linseed oil or perilla oil on the one hand and half-drying or non-drying oils on the other hand to a common esterification with glycerol or other poly-alcohols. The glycerol, if used in excess and non-esterified, may be distilled off in vacuum, or the excess of glycerol may be esterified with colophony or suitable copal melt residues, with or without a subsequent vacuum distillation. The fatty acids of one or more oils may be heated with a fatty oil or a mixture of fatty oils to change the esterification and the free fatty acids may be subsequently esterified with glycerol. The fatty acid mixture of good drying oils may be replaced partly or completely by a mixture of the isomeric linolic acids with conjugated double bonds obtained from ricinoleic acid according to Specification 306,452. In examples. (1) a. mixture of soyabean-oil acids and the isomeric linolic acids with conjugated double bonds (obtained from ricinoleic acid); and (2) a mixture of wood-oil and poppy-seed-oil acids are esterified with glycerol.

In operation compressed air is cooled to saturation temperature in an exchanger 12 having product gaseous oxygen and nitrogen lines 13, 14 and is then passed through a line 15 to column 16 from which said high-pressure gaseous material is withdrawn through a line 75 and is in part passed through the exchanger 60 whilst the remainder is warmed in a line 83 expanded at a turbine 85, and fed through a line 86 to the column 25. In a modification the high-pressure gaseous material poorer in oxygen than is the crude liquid oxygen in the base of column 16 forms part of the cold wet air feed to said column and is liquefied in two exchangers in series. In a further modification gas material withdrawn from the column 16 is liquefied in exchangers in parallel with respect to said flow material but in series with respect to the flow of liquid oxygen from the base of the low-pressure column.

Abstract: 159,975. Lord, F. J., and Taylor, R. A. Dec. 9, 1919. Shaft couplings.-The magneto of an internalcombustion engine is driven from the engine shaft by means of a coupling member on the magneto shaft and a coupling member on the engine shaft connected together by a manually adjustable member which gives a rotational lead or lag to the magneto shaft relatively to the engine shaft for advancing or retarding ignition. As shown, the engine shaft 10 and the magneto shart 11 have concentric hollow extensions 16, 15 respectively provided with slots 38, 37 traversed by a pin 35, these slots being inclined to each other. The ends of the diametral pin 35 fit into a groove 34 in a ring 27 provided with studs 28 - engaged by slots in a fork 31, which is pivoted on set screws 32 and provided with a knob for connection to a manual control. The studs 28 are guided by slots 29 in the casing so as to move parallel with the shafts and thereby cause the diametral pin 35 to impart relative rotation between the shafts by its action on the slots 38, 37. The pin 35 is held in place by a split sleeve 39 which grips the part of the pin within the extension 15, 16. A notch 40 in the pin 35 is engaged by a dent in the sleeve still further to prevent displacement. The extension 16 is secured to the engine shaft 10 by a split socket 13 tightened by a bolt; and the extension 15 is connected to the magneto shaft 11 by a dog-clutch 12. Ball bearings 23, 24 are provided for both shafts. The casing is divided longitudinally in two parts secured together by bolts; and the bottom of the casing is made flat to facilitate its mounting on the engine. Reference has been directed by the Comptroller to Specifications 26590/05, 24403/08, 3125/10, 9070/13, 109,793, and 109,794, [all in Class 35, Dynamo-electric generators &c.].

In Fig. I plates 20 are lowered by delivering gas to bellows 18, and as the gas pressure rises further this gas aatuates the pneumatic diaphragm valve sirens 11 and escapes into bags 12 to assist cleaning thereof by reverse flow. In Fig. 2 (not shown) the bellows have separate gas supplies so that bags can be cleaned singly or in groups while the others continue to filter. The housing may be lined with mineral wool to reduce external noise, but as shown section 2 is of concrete. The plates could alternatively be moved mechanically, and the means 11 could be electrically powered.
