Title: Pattern Recognition
Inventor: YARNELL JOHN
IPC: G06V10/88
Filed: 1966-06-29
Abstract: 1,189,443. Pattern recognition. HAWKER SIDDELEY DYNAMICS Ltd. 18 Sept., 1967 [29 June, 1966], No. 29289/66. Heading G4R. [Also in Division G2] An unknown pattern is recognised by modifying its diffraction pattern by means of a hologram of each of a plurality of known patterns in turn, or a hologram comprising all the known patterns separated in space, to derive the crosscorrelation function of the unknown pattern with each known pattern, and detecting which function has the brightest spot. In preparing the hologram plate or plates, the total light falling on it/them is made the same in the case of each pattern. In the case of recognition using one hologram (matched filter) comprising all the known patterns separated in space, the hologram output (after image intensification using an image converter, or T.V. camera and cathode-ray tube, if necessary) is projected on to a bleachable plate, an array of detectors indicating where the plate bleaches significantly first.

Title: Improvements in or relating to a process for the enrichment of ammonia in deuterium
IPC: B01J27/24
Filed: 1960-08-25
Abstract: <PICT:0951791/C1/1> In a method of enrichment of ammonia in deuterium by a dual-temperature isotopic exchange between liquid ammonia and a gaseous phase comprising hydrogen (e.g. hydrogen or ammonia synthesis gas), in which the gaseous phase is saturated by direct contact in a scparate exchanger with the vapour of the liquid phase which contains a non-volatile alkali metal amide as a catalyst of the isotopic exchange, liquid ammonia containing catalyst circulating in a closed circuit to make up the quantity of ammonia removed in the saturated gaseous phase, the accumulation of non-volatile dissolve catalyst is avoided by introducing into the circuit a make-up quantity of liquid ammonia containing catalyst, said quantity being equal to the quantity necessary for saturation of the gaseous phase plus a quantity which is at least adequate to allow, by withdrawal of the liquid having the most catalyst, at a point of the circuit located adjacent to the outlet of the separate exchange, the removal of a quantity of catalyst which is at least equal to the quantity which has been introduced with the make-up liquid.  In Fig. 2, ammonia leaves cold tower F and enters hot tower 1 via 3, and travels via 4 and 5 to tower 2 which is the separate exchanger for saturating the gaseous phase.  The gaseous phase enter tower 2 via 6 and trowels via 7 to hot tower 1 and then via 9, heat exchanger 10, and 11 to the cold tower F.  A closed circuit of liquid ammonia containing catalyst comprises tube 15, tower 2, tube 12, heat exchanger 10, tube 13, and reheater 14.  In tower 2 part of the ammonia is removed in the gaseous phase. The circulating ammonia is supplemented by that leaving hot tower 1 via tube 5, and a conduit 16 in tube 12 is used to drain off ammonia which is more concentrated in catalyst than that entering tower 2. Thus the build-up of catalyst in the circulating ammonia is avoided.

Abstract: 808,233. Slot seal and ware-supporting apparatus for furnaces. TEISEN, T. Sept. 20, 1957 [Sept 27, 1956], No. 29509/56. Class 51 (2). In a furnace for the heat treatment of metal articles in which the work is hung on hooks depending from an overhead conveyer through a slot in the furnace roof which is closed by skidplates attached to the hooks, the slot is enclosed by an air chamber and a fan supplies air to the chamber at a pressure greater than that within the furnace. The shanks of the hooks d depend from a conveyer e through a slot g in the top of an air chamber f mounted on the roof of the furnace enclosing a slot c through which the hooks d extend into the furnace. Skid-plates h slide in guides k to close the slot in the air chamber f and skid-plates i slide on guides m to close the slot c. A fan n supplies air to the chamber f, which has damper-controlled outlets p. The pressure of air in the chamber is greater than the pressure in the furnace, but not great enough to cause excessive flow of air into the furnace. In a modification, two air chambers are mounted one above the other on the furnace roof, the hooks extending through both chambers, and the fan supplying air to both chambers through a branched pipe and each chamber having dampered outlets. The arrangement cools the hooks, conveyer, and skid-plates. The air chambers may be divided longitudinally.

Title: The detection of excessive speed of a moving body
IPC: G01P1/10
Filed: 1969-06-12
Abstract: 1279139 Detecting particular speeds SOC NATIONALE INDUSTRIELLE AEROSPATIALE 12 June 1969 [14 June 1968] 29929/69 H Heading G1K [Also in Division H1] A method of detecting (and stopping) the exceeding of a predetermined speed limit by a moving body E includes the steps of stopping its movement upon the change of state of a circuit P capable of assuming only the two states "interrupted" and "established" and of effecting this change of state by bringing three openable and closable members I 1 , I 2  and I 3  of a circuit 1, simultaneously to closed position when the speed exceeds the limit. Referring to Fig. 2 and Fig. 3 (not shown), cams G1 and G2 on the body E control the opening and closing of switches I 1  and I 2  by acting on rollers g 1  and g 2 . The cams are spaced a greater distance apart than the rollers so that, irrespective of direction, the body moves a predetermined distance D-l in the interval between the closing of switches I 1  and I 2  and the consequential establishment respectively of circuits 3, 4 in parallel between points p and q. The sequential closing of the switches I 1 , I 2  (or I 2 , I 1  according to the direction of movement) prepares and, if the speed limit is exceeded, renews the preparation of a time-lag relay RT for opening the switch I 3  after a time delay T. The delay T is adjusted in relation to the distances D, l to open switch I 3  in the interval between the closing of the switches I 1 , I 2  if the speed limit is not exceeded and to maintain I 3  closed while both I 1  and I 2  are closed if the speed limit is exceeded. Each cam G 1  and G 2  travels a distance D between closing and opening its respective switch I 1  or I 2  and the relay RT releases when both switches I 1  and I 2  have opened. The device is then ready to detect further movement by means of the same pair of cams or another pair according to the direction of further movement. Two or more similar devices may be connected in parallel, Figs. 6, 7 (not shown). The changes of state of the circuits may be obtained by means of photo-electric cells instead of cams and the electric circuits may be replaced by hydraulic circuits. The embodiment of Fig. 5 (not shown) is arranged for the external supervision of the angular speed of a control shaft in an automatic flight control apparatus to de-clutch and give warning of abnormal operation. A number of devices, Fig. 8 (not shown) may be combined simultaneously to supervise automatic control of steering, banking and depth rudders.
