Patent GB-1177184-A (GB)
Title: A Line Printer Paper Feed Control System
IPC: G06K15/16
Filed: 1967-07-19
Abstract: 1,177,184. Selective signalling. FUJITSU Ltd. 19 July, 1967 [20 July, 1966], No. 33238/67. Heading G4H. In a line printer paper feed control system, in order to avoid large starting and stopping forces which might tear the paper, two paper feeding speeds are used, a slow starting and stopping speed, and a feed speed, which is only used if the paper has to be fed sufficiently far, for the central position of the displacement. The system is controlled by eight-channel paper tape, Fig. 5, each channel corresponding to a specific line-format programme, and each punch hole indicating the number of the line on which printing is to occur. In prior systems the printing paper and programme tape have been advanced synchronously, each advance occurring after a line has been printed and continuing until the next hole in the operative channel on the tape is sensed. In the system described whilst one line is being printed the programmed tape is advanced independently of the printing paper until the next hole in the operative channel is sensed. As it advances the sprocket holes are sensed and the pulses produced entered into a control counter. When printing of the current line is complete, the printing paper is advanced and pulses are produced, one per line, and entered subtractively into the control counter until it reaches zero. The printing paper will then be in position for the next line of print. The speed of the printing paper is controlled by the control counter, and the arrangement is such that the paper is always started and stopped at the slow speed, but if it has to move sufficiently far, and this is determined by the content of the counter, then the speed is increased to the high speed for the central portion of the displacement.

Filed: 1937-12-03
Abstract: 506,811. Distributing music &c NOLTE, C. H. Dec. 3, 1937, No. 33534. Convention date, Dec. 5, 1936. [Class 40 (iv)] In a system for distributing recorded matter to subscribers, a number of spaced pick-up devices are associated with a single sound or image record and an arrangement is provided whereby a subscriber's loudspeaker or other reproducer is connected to that pick-up which will be the first to be reached by. the starting point of the record. As shown, three pick-up devices 4 are associated with an endless film record 1 which passes through three magazines 25 and is pressed against a central drum 13, each pick-up being connected to an amplifier 5. As the film advances, a conductive contact 10 carried thereon closes in turn contact springs 9<SP>1</SP>, 9<SP>11</SP>, 9<SP>111</SP>, of which the first two connect up a magnet 8a to lift a shaft 12 one step and the last a magnet 8b to restore the shaft 12. The shaft 12 carries a number of contact drums 11, one for each subscriber, which are coupled to the shaft through springs 11<SP>1</SP> and are arranged to connect the subscriber's leads 24 to the output leads 20 of any one of the amplifiers 5 in accordance with the position of the shaft 12 when relay 7 operates in response to the closure of the subscriber's key 2. Relay 7 also switches on the driving motor 16 if necessary, connects supply current to the appropriate pick-up 4 and amplifier 5 over leads 21, and locks the drum by the engagement of a detent 14 with one of three notches 15. When relay 7 is released, the drum 11 assumes its normal position in relation to the shaft 12 by the action of the spring 11<SP>1</SP>. Instead of the conductive contact 10 and contact springs 9<SP>1</SP>, 9<SP>11</SP>, 9<SP>111</SP>, other means such as a black spot controlling photoelectric cells may be used for connecting up the magnets 8a, 8b. The film may carry a number of parallel tracks co-operating with separate pick-ups, the trabks being associated with parts of a single programme or with different programmes, the keys 2 being replaced by selecting devices in the latter case.
Patent GB-807581-A (GB)
Title: Production of alkynols and alkynediols
IPC: B01J23/843
Filed: 1955-11-23
Abstract: Alkynols (including alkyndiols) are made by reacting aldehydes or ketones with acetylene (see Group IV (b)) in the presence of a catalyst made by depositing copper oxide on a siliceous carrier which is then heated to a temperature of 400 DEG  to 800 DEG  C., by which a surface layer of copper silicate is formed.  Preferably a little bismuth oxide is present with the copper oxide.  The metal silicate prevents the formation of cuprene.  Kaolin, silica gel, or fuller's earth may be used as the carrier, but preferably kaolin is mixed with an organic binder, formed into shapes and roasted at 800 DEG  to 850 DEG  C. to burn out the binder, and finally heated at 1000 DEG  to 1200 DEG  C. to impart a mullite-like structure. Binders specified are, polyacrylic acid, alginic or pectic acid, polyvinyl methyl ether or methyl cellulose.  In examples, the calcined carrier is impregnated with a solution containing copper nitrate or nitrite, bismuth nitrate and dilute nitric acid.  The pulp is extruded, and the shaped pieces dried and finally heated at 400 DEG  to 800 DEG  C. for 5 to 34 hours.  The bismuth compound may be replaced by compounds of Au, Hg, Pb, Se, Ce, or of halogens. U.S.A. Specifications 2,232,867 and 2,300,969 are referred to.ALSO:Alkynols (including alkyndiols) are made by reacting aldehydes or ketones with acetylene in the presence of a catalyst made by depositing copper oxide on a siliceous carrier which is then heated to a temperature of 400 DEG to 800 DEG  C., by which a surface coating of copper silicate is formed, thus preventing the formation of cuprene.  Preferably, there is also present a small amount of an oxide of Bi, Au, Hg, Pb, Se or Ce. Kaolin, silica gel, or fuller's earth are used as carrier, but preferably kaolin is mixed with a polymeric organic binder, the mixture formed into shapes, dried, calcined and then impregnated with solutions of the metal salts and re-ignited (see Group III).  In examples, a long tubular reactor column packed with the catalyst is first flushed with nitrogen, and then heated to 90 DEG  C., while a 6 per cent formaldehyde solution trickles downwards through the column. Acetylene is bled into the nitrogen feed increasing to a concentration of 70 per cent acetylene, and also the temperature is raised to 120 DEG  C.  The concentration of formaldehyde is also raised to 18.5 per cent.  The gases produced are condensed, surplus gases recycled, and water removed from the condensate, which is then submitted to azeotropic distillation.  In a 600 hour operation, 80 per cent of the formaldehyde is converted to alkyne diol.  U.S.A. Specifications 2,232,867, 2,300,969 and 2,527,358 are referred to.
