Patent GB-810265-A (GB)
Title: Process for the production of gas containing hydrogen by the conversion of hydrocarbons
IPC: C01B3/46
Filed: 1956-02-21
Abstract: <PICT:0810265/III/1> The process of the parent Specification is carried out in an apparatus containing two layers of catalyst, each positioned on a gasand liquid-permeable support, with the gases discharged from the first catalyst layer passing towards and through the second catalyst layer, and the second catalyst layer is brought to a different temperature from the first layer during the heating phase.  In the parent Specification, hydrogen-containing gases are prepared in successive cycles, each comprising heating and conversion phases separated by steaming phases and the initial gases for each phase are passed towards and in contact with the catalyst, while gases resulting from each phase are discharged through the catalyst. Fuel is supplied at 4 and air at 3 to burner B1 to heat first layer 2 of nickel on kaolin catalyst in reactor 1, and the combustion gases are withdrawn through 14 to second catalyst layer 12 in reactor 11, which is also equipped with burner B2 supplied with fuel at 4 and air at 3.  The combustion gases are withdrawn at 8.  When layer 2 is at 750 DEG  C., and layer 12 at 770 DEG  C., the apparatus is purged with steam from 6, and the catalyst may then be reduced by passing some of the product hydrogen gases through.  In the subsequent conversion, liquid hydrocarbon may be injected through 5, with steam entering through 6, and the hydrogencontaining gases pass through 14, reactor 11 and hydraulic non-return device 15, to the outlet at 9. Alternatively, a mixture of gaseous hydrocarbon and steam is injected through pipes 7, and the product gases pass through 13 to reactor 11. The two catalysts may be different, and in the case of the reaction of natural gas and steam, the reaction in the second catalyst layer may be endothermic, e.g. removal of residual methane, when the second layer is at a higher temperature, due to the supply of additional combustion gases through burner B2, or may be exothermic, e.g. the conversion of CO with steam to CO2 and H2, when the second layer is at a lower temperature, due to non-operation of burner B2, or to the supply of cold gas through the burner assembly.

Title: Improvements in or relating to fluid-control valves
IPC: B23Q35/36
Filed: 1956-02-21
Abstract: 792,748. Fluid-pressure servomotor-control systems; valves. HOLMES, S. H. Feb. 21, 1956 [May 25, 1955], No. 5383/56. Class 135. [Also in Group XXII] Servomotor-control system.-A workpiece 14, Fig. 1, is lathe cut to a desired contour by the tool 17 on a base 13, the transverse motion of which is effected by a piston 20 in a cylinder 19 that is connected to a valve 25 by pipes 23, 24, the valve having a pressure inlet and two return lines 26 and 27, 28, respectively; a stylus 29 follows a template 30 and actuates the valve; the valve 25 is mounted on the base 18. Electrically operated by-pass valves 31, 32 provide for direct connection of the inlet pipe 26 to the cylinder 19. Control valve.-A casing 33, Fig. 3, houses a number of stationary annular discs 41-47, the discs 43 and 45 having a greater internal diameter than the others, whilst between discs 41, 42 and 46, 47 two resilient sealing diaphragms 50, 51 are clamped, which diaphragms carry a rod 52 with a head 53; annular rings 54-59 are supported on the rod 52, rings 56 and 58 being shorter and of larger diameter than the others and extending into the discs 43, 45. Leftward movement of the rod 52 causes rings 56, 58 to abut discs 41, 44 and reverse the inlet and exhaust connections to the cylinder 19, since each disc has a radial duct 23a-28a that is in circuit with the corresponding line or pipe 23-28, Fig. 1. Rightward movement of the rod 52 causes rings 56, 58 to abut discs 44, 46 and again reverse the connections to the cylinder 19. Actuating mechanism.-A pivot on the head 53, Fig. 3, co-operates with a plate 61 moved by axial and/or radial motion of the stylus 29 in a carrier 68 resiliently disposed in a bush 71 that is mounted through ball bearings 75 in a sleeve 75, the carrier 68 and plate 61 coact via a ball 66. The other end of the plate 61 contacts the resilient button of a micro-switch 64 and/or other apparatus, not shown, to energize solenoids and actuate by-pass valves 31, 32, should the plate 61 be urged beyond the limit of travel of the rod 52. The by-pass valves may be dispensed with and the switches replaced by a spring. Adjustable stop.-An adjustable spring 60 always urges the stylus and rod 52 to the right, which spring surrounds a stop limiting such movement comprising a flanged sleeve 101 fixed to the rod 52 in which slides a block 100 in the end of a threaded stem 81 held against rotation by an hexagonal pin 91, the stem supporting an abutment 83 for the outer end of the spring 60. The stem 81 is screwed into a threaded member 77 whereby any rough adjustment of the latter effects a fine adjustment of the spring 60 and stem 81, and hence of the stop, thereby determining the relationship between rings 56, 58 and discs 44, 46 in the extreme right-ward position of the rod 52.

Abstract: 825,481. Batteries. ELECTRIC STORAGE BATTERY CO. Feb. 18, 1957 [March 27, 1956], No. 5383/57. Class 53. An electrode for a sealed alkaline accumulator is produced by impregnating a porous carrier with a metal formate, e.g. nickel or cadmium formate, which is decomposed to form the active material. The carrier may be impregnated with the metal formate directly by vacuum treating the carrier to remove occluded air and then impregnating it with a 10-20% solution of the desired formate. Alternatively, the formate may be formed in situ by impregnating the carrier with a solution of the corresponding nitrate and then heating it in the vapour of an aqueous formaldehyde solution or an aqueous formic acid solution. The formate can be decomposed by drying the impregnated carrier and heating it, in the case of nickel formate to 400-410‹ F., or alternatively by exposing the wet impregnated carrier to an atmosphere of water vapour and ammonia and heating under reduced pressure to distill off the ammonium formate so formed. The impregnation and decomposition steps may be repeated. The carrier may be of porous nickel or of porous carbon produced by process described in Specification 687,201.

Abstract: 1495784 Video recording equalization PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 12 Feb 1975 [15 Feb 1974] 5952/75 Headings H4R and H4F In an apparatus for reading a disc on which a frequency modulated video signal is optically recorded variations in the frequency response of the reproducing system which occur as a result of changes in the radial position of the reading head during reproduction of the record are compensated by feeding the detected video signal through a correction filter whose characteristic is varied by a signal which is derived by comparison of the amplitude of the frequency modulated carrier signal, after integration to reduce the effects of short term signal modulation products, with a reference signal, which may be derived from a low frequency pilot or audio signal recorded on the record. As described the video signals are recorded on the disc by frequency modulating a carrier with the luminance information of a colour TV signal so that black level corresponds to 5À2 MHz and peak white 6À5 MHz, chrominance information is recorded on a carrier of 1À5 MHz and audio channels and a pilot signal in the band below 1 MHz. The video signal read from the disc is applied to a variable filter 8, the luminance information is picked out by a filter 7, passing the band 5À2 to 6À5 MHz and applied to an amplitude detector 6. The resulting signal, which has relatively fast amplitude variations due to signal frequency variations, and longer term amplitude variations due to change in the record reading radius, is fed through an integrator circuit 5 to remove the fast amplitude variations and then compared in 4 with a reference signal to provide a control signal for the variable filter 8. The reference signal may be a fixed reference from source 10 or may be obtained by filtering, at 2, and detecting, at 3, a low frequency pilot signal or frequency modulated audio signal in the reproduced signal.
