Patent GB-338177-A (GB)
Abstract: 338,177. British Thomson-Houston Co., Ltd., and Johnston, A. J. July 9, 1929. Totalizators.-In totalizator apparatus wherein an impulse through the totalizing equipment initiates operation of the ticket-issuing machine through a relay, an auxiliary contact on the armature of the relay is provided so as to interrupt the impulse circuit until the relay is restored to normal at the end of the ticket-issuing operation. As shown, the keys 2, for issuing tickets on different horses, when operated complete circuit from the totalizing-equipment through a distributor 3, a pair of contacts 12 and the relay 1. The armature 5 when attracted is held by a latch 7, completes circuit for the ticket-machine motor- 9 and breaks the impulse circuit at 12. The latch is actuated to free the armature again at the end of the operation, by a cam 10 and the depressed key is restored by a cam 11. Specification 337,775 is referred to. Reference has been directed by the Comptroller to Specifications 201,152, 231,507, and 307,551.

Abstract: 1,076,926. Road traffic signals. MINISTER OF TRANSPORT and AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. Aug. 20, 1965 [Aug. 20, 1964], No. 34102/64. Heading G4Q. A vehicle presence detector (3) in the approach to a road junction maintains right of way on a road already possessing right of way so long as a vehicle is moving within the range of the detector. A second vehicle presence detector (5) may cover the actual junction and extend the inter-green period (which may include an all-red period) until the junction is clear. Alternatively the detectors in the approach roads may extend half-way across the junction (Fig. 5, not shown). The presence detectors may be inductive loops which cease to give an output shortly after a vehicle comes to rest within them, and may each cover a single lane or a plurality of lanes. A presence detector may be preceded by a passage detector, operation of which registers a demand if the road does not possess right of way or grants a fixed extension sufficient to allow the vehicle to travel to the presence detector if the road already has right of way. The passage detector may comprise a pair of road pads (1, 2) adapted to discriminate against actuation by a vehicle travelling in the wrong direction.

Abstract: 1,178,978. False-twisted yarn. IMPERIAL CHEMICAL INDUSTRIES Ltd. 19 July, 1967 [29 July, 1966], No. 34230/66. Headings D1D, D1F and D1W. A filamentary yarn or tow is false-twisted by passage between two rotating spiralsurfaces of opposite hand. The rotational speed of the surfaces is so adjusted with respect to the yarn speed that the same points of the yarn remain in contact with the spiral surfaces as the yarn advances parallel to the axes of the spirals. Alternate lengths of the yarn are twisted in opposite directions by the two spirals. The yarn may be pre-heated and hot and cold zones may be provided on the spiral surfaces - with optionally the coefficient of friction of one spiral surface being less in the cold zone than in the hot zone so that the amount of twist is not increased further - or the cold setting zone may be provided on a plain roll having a coefficient of friction high enough to prevent the S and Z twists cancelling each other out before the yarn is cooled. The alternately twisted yarn may be bulked by subjection to repeated extension and contraction or by being passed through an acute angle over a guide. The spirals may have multiple threads and the false-twisting process may be combined with a drawing or a spin-drawing process. Specification 1,178,397 is referred to.

Abstract: 1398438 Selecting alternative memory locations INTERNATIONAL BUSINESS MACHINES CORP 24 July 1972 [18 Aug 1971] 34452/72 Heading G4A A data store includes a memory array having several addressable lines of bit locations, a read only memory storing the address of a defective line, and a comparator having its output connected to an alternative line of bit locations provided in the memory array and arranged to compare an address supplied to the array with the address stored in the read only memory and, in the event of equality, to generate a pulse on its output to select the alternative line of bit locations. The memory is formed on a number of cards 12 each containing one or more integrated circuit chips, only one of which is shown. The memory 9 has nine word lines 31-39 and eight bit lines 21-28. The word lines 31-38 are normally selected by address decode circuits 40, the ninth line 39 being a spare. Following manufacture the memory is tested. If more than one word line contains a defective cell the memory is discarded. If no lines are defective the memory is used conventionally. If one word line contains a defective location its address is stored in read only memory 54 so that when subsequently the defective line is addressed comparator 52 generates an output on line 55 to disable the address decode circuits 40 and select the spare word line 39. More than one spare line may be provided with a read only memory and comparator for each spare line. In this way memories with more than one defective line may be used.  Suitable circuits are described for the decoders 40, comparator 52, and read only memory 54. The read only memory consists of fusible links which are selectively blown to store the address of a defective word line, the comparator consists of transistor exclusive-OR gates, and the word line decoders consist of transistor NOR circuits.

Abstract: 1536220 Image spectral analysis DAINIPPON SCREEN SEIZO KK 19 Aug 1976 [20 Aug 1975] 34530/76 Heading H4F A method of correcting logarithmic colour separation density signals D R , D G , D B  provided by a scanner 1, 2, comprises: providing means 3 for compressing signals into ranges D<SP>1</SP> R , D<SP>1</SP> G , D<SP>1</SP> B  reproducible by printing inks, an A/D converter 4, and a memory 5 for storing correction signals; using the digitized compressed signals C 1 , M 1 , Y 1  as addressing signals for reading out stored correction signals #C, #M, #Y; and adding the correction signals to the digitized compressed signals. The correction signals #C, #Y and #M represent the differences between the digitized compressed signals C 1 , M 1 , Y 1  and pre-estimated colour separation density values C, M, Y of a finished print, which are preferably the END (equivalent neutral density) values. The generation of the approximate signals C 1 , M 1 , Y 1 , each one independently from a respective signal D<SP>1</SP> R , D<SP>1</SP> G , D<SP>1</SP> B , and their subsequent correction, mean that the memory 5, instead of storing a unique combination of C, M and Y signals corresponding to every combination of D<SP>1</SP> R , D<SP>1</SP> G  and D<SP>1</SP> B  signals, is only required to store corresponding combinations of #C, #M and #Y, which are substantially smaller and in some instances may be zero. Furthermore, since the correction signals #C, #M and #Y vary only gradually with D<SP>1</SP> R , D<SP>1</SP> G  and D<SP>1</SP> B , the addresses at which they are stored are fewer in number than the combinations of D<SP>1</SP> R , D<SP>1</SP> G  and D<SP>1</SP> B . Corrected signals C, M, Y may be reconverted to analogue signals at 7 and pass through a tonecorrection circuit at 8 and an anti-logging circuit 9 to be used for exciting a driving circuit 10 for exposure beams used in producing colour separation negatives.
