Title: Pattern recognition systems
Inventor: ROBINSON THOMAS EDWARD
IPC: G06V10/75
Filed: 1970-04-30
Abstract: 1,242,039. Pattern recognition. INTERNATIONAL BUSINESS MACHINES CORP. 30 April, 1970, No. 20836/70. Heading G4R. A pattern recognition system comprises input means for reducing an input pattern into the form of a bit string, a plurality of associative memory units having their inputs connected in parallel to the output of the input means arranged to respond if the bit string conforms to words or combinations of the words stored in the memories, and output means connected to the output of the associative memories for producing output signals representative of patterns determined by the outputs of the associative memories. The bit string is supplied (for matching) to the associative memories via a further select" associative memory which supplies successive parts of the string in turn together with control keys. The associative memories may be as in Specification 1,186,703 (referred to). A control and timing unit including a read-only store and a clocking system, controls the associative memories &c., supplying control keys to the associative memories which achieve match only in the memories for which they were intended. The number of associative memories connected in parallel can be increased without altering the rest of the system, and any of these memories can be extended by adding further memories in series. Matching in these associative memories (to identify the pattern) can be done with the output of a further associative memory used first to identify features of the pattern. If the bit string is parallel-by-bit, the "select" memory may be simplified or dispensed with. A buffer store may precede the select" memory. The bit string may come from a flying spot scanner.

Title: Improvements in the compressed air starting of reversible diesel engines
IPC: F02N9/04
Filed: 1947-08-01
Abstract: 646,437. Starting. WHITFIELD, J. E. Aug. 1, 1947, No. 20958. Convention date, Sept. 27, 1943. [Class 7(v)] [Also in Group XXVIII] In a circuit for starting a reversible Diesel engine by compressed air, comprising an air pressure supply 62, a normally closed master-relay valve 64 which when open connects the air supply to the cylinder or cylinders of the engine, a manually operable control valve 71, an air pressure operated motor 75 for moving a starting air distributer 79 and engine fuel cams 78 to positions for operation of the engine in forward or reverse, an air pressure operated double-acting servomotor 10 for actuating a scavenging-air blower reversing-valve (not shown), a pair of air pressure control lines 72, 73 connecting, the associated sides of the servomotor, the motor and the manually operable control valve, the latter being movable for connecting either one of the control lines to the supply and the other to exhaust, there is provided a third air pressure control line 81, that is connected to valve 64 and receives air under pressure from the servomotor to open the valve 64 to supply air under pressure to the engine cylinders to start the engine. The supply line 62 is connected to the lower chamber 63 of the relay valve 64, which latter incorporates a valve member 65 attached to a stem the other end of the stem having a spring-loaded piston 67 secured thereto so that the spring loading and the air in the chamber 63 tend to keep the valve member 65 closed until air is directed into the piston 67. The air in chamber 63 therefore traverses a conduit 70 and depending upon the position of the manual valve 71, either one or the other of lines 72 and 73 is supplied with air and the other is connected to exhaust. With the valve 71 in the position shown. air is conducted through the first part of the line 72 and operates the piston motor 75, which in turn axially shifts a cam shaft 77 with its associated fuel cams 78 and starting air distributer 79 to set .the engine for forward operation. One of two openings 80 in the rod of piston 75 is now in position to provide communication between the first and second parts of line 72 thereby permitting air to enter the servomotor 10 (see also Group XXVIII) by means of a slide valve 57 attached to the latter and so condition the blower reversing valve for forward operation of the engine. The air leaving the servo-motor 10 travels along the line 81 to act upon piston 67 and so open valve 64 to admit air from line 62 into a conduit 82 and through starting valves 83 controlled by the distributer 79, into the engine cylinders. When the line 73 is supplied with pressure air and the line 72 is connected to exhaust the engine starts in the reverse direction.

Filed: 1951-09-05
Abstract: 692,606. Butterfly valves. HARZA. L. F. Sept. 5, 1951. No. 20967/51. Class 135 A butterfly valve for a passage 12, Fig. 1, e.g. leading to a hydraulic turbine or being the discharge passage through a dam 14, comprises a closure member 10 pivoted by trunnions 16 over the part 20 of the passage, and having tapered arms so that when open, the member smoothly joins the larger and smaller parts of the passage. The lower arm 10b of the member controls flow through the passage and the upper arm 10a, slightly larger than the lower, moves in a chamber 18 having a connection 70 to the inlet pressure, e.g. the dam head water, controlled by a valve 72, and a connection 74 to the outlet controlled by a valve 76. A chamber 40 formed behind the lower arm has a connection 80 to the atmosphere controlled by a valve 82. These valves are mounted in a gallery 52 into which the member 10 may be raised by tackle 66 for repairs, after the trunnions 16 are withdrawn by worm and wormwheel 60, Fig. 3, which rotates opposite handed threads 56, the worm having a shaft extending into the chamber 18 and operable from the gallery after removing a plate 50. To close the valve, the chamber 18 is connected to the outlet and pressure in the passage 12 acts on the upper arm to turn the member 10 until the edge 44 engages a sealing insert 24, the chamber 40 being opened to atmosphere to prevent vacuum and hence vibration of the member. To open the valve, chamber 18 is connected to the inlet whereby the arm 10a is balanced, and the pressure in passage 12 acts on the arm 10b to turn the member to open position. The member may be operated by extending one trunnion for engagement with a power driven crank, or a rack and pinion may be used. Sealing strips, e.g. of rubber, are provided in slots in the member, and the space behind the strips may be open to inlet pressure, the strips engaging liners e.g. of bronze, in the passage walls,

Title: Improvements in electric fire alarm systems
IPC: G08B17/06
Filed: 1955-07-20
Abstract: 811,169. Electric fire alarms. EKMAN, O. 1. H. July 20, 1955, No. 20967/55. Class118 (1). An electric fire alarm comprises a pair of leads a and b extending through the area to be protected and connected at one pair of ends to a battery at a central station and at their other ends to earth via alarm relays AR1, AR2, alarm boxes 1-10 having resistors R1-R10 and capacitors 02-C10, and alarm loops such as S5 and S10 containing ten or more thermocontact pairs T. Central station apparatus shown below the dotted line in Fig. 1 comprises two similar . hand-operated group selector switches VGS and HGS each of which may be connected into a bridge circuit as shown in Fig. 5, a transformer such as VTF connected across the neutral points of the bridge and operating indicating lamps VGL, VOL and VSL, and contact pairs 102 which may operate upon movement of the selector switches (VGS for example) to shunt balance capacitors VSC and LUC and replace them by the balancing impedances of the switch and part of the thermally-operated lines a, b. The system is normally energized. by D.C. and the motor of the motor generator is also connected to the D.C. supply, the generator giving A.C. for checking the balance of one or other of the bridge circuits which may be established by the operator rotating switch GSO either clockwise or anticlockwise and operating the group selector switches in succession. In operation, when the leads a and b have opened the relays AR1 and AR2 actuate an alarm device (not shown) which indicates that the switch GSO is to be rotated. Movement of this switch operates a relay GSR which starts the motor generator, cuts out the D.C. supply to the leads a, b, and connects the generator and leads into the bridge. The bridge is then balanced against the lead impedances by rotating the contact bar 100 of, say, the switch VGS by means of a knob 101, and a check on the alarm point is made by rotating the switch GSO in the opposite direction and operating the other group selector switch HGS. At bridge balance the dimmed lamp VGL is extinguished, relay VBR is de-energized and closes contacts to light lamps VOL and VSL. The alarm loop number is shown on a lamp indicator operated by the knob 101.

IPC: D01D10/04
Filed: 1943-12-14
Abstract: High tenacity, low elongation viscose rayon threads or yarns suitable as reinforcing elements in tyres, hose, belting and the like, are obtained by withdrawing at a uniform speed freshly spun highly stretched viscose threads in the acid condition from a plurality of adjacently mounted packages and passing them before drying in closely-spaced parallel relationship through washing, after - treating and finishing baths, simultaneously stretching and drying <PICT:0577580/IV/1> them, the stretch being applied by means of a plurality of thread propulsion surfaces and collecting the dried finished threads in parallel relationship on a common beam.  The initial packages may comprise freshly spun and coagulated viscose thread, highly stretched in the two-bath spinning process and collected on a bobbin or in a centrifugal bucket.  A plurality of packages of viscose threads 1 in the acid condition are unwound and treated in parallel relationship in a series of baths 6, which may comprise washing liquids such as water or dilute acid and desulphurizing, rewashing and finishing fluids, and then in an oil-emulsion finishing bath 8.  An assembly of rollers 10 prevents the threads from slipping as they are led from the bath 8 to a slasher unit comprising a plurality of tensioning and drying rollers 11 which may be steam heated.  The peripheral speed of the first roller of the slasher is greater than that of the roller assembly 10, so that stretching of the threads is effected as drying commences. The threads are further tensioned by roller assembly 13 rotating at a higher peripheral speed than the rollers of the slasher unit, and finally collected on beam 14.
