Title: Production of hydrogen
IPC: C07C1/02
Filed: 1974-08-29
Abstract: 1492785 Hydrogen TEXAS GAS TRANSMISSION CORP 29 Aug 1974 [9 Nov 1973] 37833/74 Heading ClA [Also in Divisions C5 and G6] Hydrogen is produced by decomposition of H 2 O into H 2  and O 2  by exposure of the H 2 O to energy from a nuclear fusion reaction. The hydrogen may be reacted with carbon, CO, or CO 2  to form a hydrocarbon fuel. In the apparatus shown, a fusion pellet is introduced into reaction chamber 10 from injection device 32 and is fired by laser energy directed through tube 38. Water vapour present in chamber 10 is decomposed and the gases issue through separation nozzle 14 which may be designed for supersonic flow, oxygen being removed at 18 and hydrogen led to methanation plant 47. The nozzle may include a grid of ZrO 2  ceramic through which O 2  diffuses more rapidly than H 2 . The chamber 10 is surrounded by a lithium blanket 20, lithium being circulated through heat exchanger 76 and tritium separation plant 82 and used to heat plant 84 where water is decomposed into H 2  and O 2 . This decomposition is assisted by radiolytic converter 90 driven by gamma rays and alpha particles generated in neutron conversion chamber 92. The plant 84 is also heated by nuclear energy from loop 24 connected by pipes 86, 88. Hydrogen and oxygen are also produced in radiolysis blanket 28 and separated at 100. Water is introduced into chamber 60 where it boils and decomposes partially into H 2  and O 2 ; separation takes place at 66, the residual water vapour being led by pipe 72 into reaction chamber 10. A carbon-containing material, e.g. coal or limestone, passes through channel 40 where it is heated to produce carbon or carbon dioxide which is directed to chamber 47 where it reacts with hydrogen from the chamber 10 to form methane. In the apparatus of Fig. 2 (not shown), the channel 40 is replaced by a further jacket (110) round the chamber 10 through which a heat transfer medium, e.g. lead, circulates and heats the carbonaceous material in an external heat exchanger (116). Specification 1,492,786 is referred to.

Title: Improvements in or relating to pitch-compensating cinematographic printers
IPC: G03B27/08
Filed: 1960-11-04
Abstract: 889,868. Kinematographic film printers. TECHNICOLOR CORPORATION. Nov. 4, 1960 [March 7, 1960], No. 37956/60. Class 98(2). A continuous kinematographic film printer has a sprocket drum 1, two presser wheels 2 for pressing the film strips against the drum, and engaging, the latter outside the sprockets, and means for guiding the negative and positive film strips N, P so as to form an arc of contact on the presser wheels where they touch the sprocket drum ; light is transmitted to the films along a path between the presser wheels: the wheels are so mounted as to be retractable and detachable, so as to be readily interchangeable with wheels of different diameter. In the form shown, the presser wheels 2 are mounted on arms 4 pivoted to a shaft 6, which also carries an arm 8. A lug 9 on arm 8 bears against a compression spring 10 which keeps the presser wheels against the sprocket drum, and the arm 8 is maintained in that position by a lock 11 which engages in a hole in the frame 15. To retract the wheels, the arm is tilted until the lock 11 engages in another hole 13. The wheel rims 14, which are attached to the wheels 2 by screws 16, can now be detached and replaced by rims of different diameter. The arrangement thus compensates for a difference in pitch between the positive and negative films due to shrinkage of the latter, and the interchangeable rims enable the apparatus to be readily adapted for varying degrees of such difference. The light housing 21 is detachably mounted between the presser wheels, and carries a lens 24 for directing the light from a suitable, source on to the film. One wheel rim carries a transparent reflecting ring 17 for printing indicia on one margin of the film by means of a light source 18.

Title: A detector for packet labels
IPC: B07C5/34
Filed: 1959-11-13
Abstract: 937,701. Detecting labels on packages. J. GAGG, and MOLINS MACHINE CO. Ltd. Nov. 11, 1960 [Nov. 13, 1959; Aug. 29, 1960], Nos. 38594/59 and 29723/60. Class 94(1). A device for detecting the absence of labels on cartons of the slide and shell type or of the type having recesses through which air may blow from one end to the other, is characterized by an air flow system which is maintained closed and under constant pressure by a labelled carton and wherein the absence of a label produces a fluctuation in pressure which causes the switch of an alarm and/or an ejection system (not described) to be actuated. In one embodiment, labelled cartons 2, moved along guides 4, pass between a nozzle 5 and press-member 6. A suction fan 7 is connected to a chamber 11 of a capsule 10, and through a valve 30 to the nozzle 5. Valve 30, Fig. 3, comprises a shuttle 16, which is reciprocated through open and closed positions by a cam 21 acting on a pivoted bell-crank 19, 23. Press-member 6 bears against shuttle 16, and is spring-biased to remain in contact with the carton 2 when the valve is in the open position. When a properly labelled carton is in the detecting position, the nozzle 5 will be closed by the label, and the system maintained under vacuum; if the label is absent air passes through the nozzle, the pressure in chamber 11 rises pushing the diaphragm against switch 14. In a second embodiment the fan operates as a blower connected directly through the chamber 11, to the valve and nozzle to maintain pressure within the chamber. The diaphragm remains in contact with the switch unless, in the absence of a label, the pressure drops.
