Title: Improvements in acoustic installations for measuring depths and distances and for like purposes
IPC: G01S15/10
Filed: 1924-06-02
Abstract: 234,994. Behm, A. June 2, 1924. Determining distances acoustically. - Relates to apparatus for timing short intervals and particularly tc apparatus of the kind described in Specification 164,011, [Class 139, Watches &c.], when used for timing echoes in acoustic depth-sounding, a disc 7 being released for rotation when a sound is emitted while a brake 6 is applied to the disc on arrival. Accord. ing to the present invention several microphones 1 - - 4, are arranged in series and act jointly to operate the brake. This arrangement ensures quick response to feeble sounds, diminishes the effect of individual fluctuations in the microphones, and provides against failure of a microphone through fracture or the like. For detecting the echo three or more microphones are assembled in a common casing, but for detecting the initial sound microphones are spaced along the ship to allow for variations in the latter's speed. Microphones may be arranged in different planes on the ship's hull for measuring lateral distances as well as depths, and they may be put out of action for the initial sound or screened therefrom by the ship's hull. According to the Provisional Specification a similar arrangement may be used for detecting subaqueous signals.

Title: Thick web dendritic growth
IPC: C30B15/36
Filed: 1963-04-04
Abstract: 977,933. Dendritic crystals. WESTING- HOUSE ELECTRIC CORPORATION. April 4, 1963 [April 30, 1962], No. 13465/63. Heading B1S. The process for the production of a dendritic body composed of at least two dendritic crystals having at least two interior twin planes connected by a web portion (Fig. 4) is modified to form a web portion at least as thick as the dendritic crystals. The dendritic body may have a concave surface on one (Fig. 11) or both (Figs. 9 and 10) sides of the web portion. The interior twin planes may or may not extend through the web portion. The thickened web is produced by reducing the rate of pulling to 0À75 or less. A silicon dendritic body having a connecting web about 1 mm. thick at its widest point is produced by pulling at a rate of about 0À5 inch/minute from a melt at 1419 ‹C. (8 ‹C. supercooling). The plano-convex form of Fig. 11 may be produced by displacing the seed from the centre of the melt or by displacing the heating means with respect to the crucible. Specifications 889,058, 913,674 and 938,915 are referred to.

Patent GB-613875-A (GB)
Title: Improvements in or relating to dyeing of threads, yarns or the like
IPC: D06P1/44
Filed: 1946-05-04
Abstract: Yarns or threads are dyed by continuously passing a single end into contact with a solution of a resin in an organic solvent, which solution also contains a water-insoluble colouring matter, the solvent being of such a nature that it evaporates quickly and leaves a thin coating of resin and colouring matter on the yarn or thread, preferably without the application of heat.  The colour may be an inorganic or organic pigment or an oil-soluble dye, and the resin may be on which polymerizes further on the yarns under normal atmospheric conditions, e.g. urea-formaldehyde and melamine-formaldehyde resins, the alkyds, methacrylates and polymerized drying oils.  In examples: (1) acetate yarn is passed through a bath containing isopropyl alcohol, ultramarine blue, polymerized methacrylate (Rhoplex-B72) and a petroleum solvent (Amsco E); acetate yarn is passed through a bath containing Dupont Oil Brown N, Acetamine Brown SR, a dispersion of alkyld and urea-formaldehyde resin containing catalyst (Sherdye Extender 19-S) and petroleum solvent (Amsco B); (3) acetate yarn is passed through a bath containing Aridye Grey LK2B, a solution of alkyd resin in hydrocarbon solvent (Reichhold P331) and petroleum solvent (Amsco E); (4) viscose yarn is passed through a bath containing isopropyl alcohol and Sherdye Blue GA, combination of Pigment Blue and Sherdye Extender 19-S); (5) nylon yarn is passed through a bath containing Sherdye Blue GF, Rhoplex B-72, isopropyl alcohol and Amsco E; (6) vinyon yarn is passed through a bath containing Sherdye Blue GP, a dispersion of alkyld and urea-formaldehyde resin containing catalyst (Aridye Clear 8850), isopropyl alcohol and Amsco E; and (7) a yarn blended from Aralac and viscose staples is passed through a bath containing Sherdye Blue GA and isopropyl alcohol.

Title: Nuclear reactor fuel element sub-assemblies
IPC: G21C5/06
Filed: 1975-03-24
Abstract: 1472298 Fuel elements UNITED KINGDOM ATOMIC ENERGY AUTHORITY 24 March 1975 [28 March 1974] 13749/74 Heading G6C A fuel element sub-assembly comprises a bundle of fuel pins (not shown) enclosed by a tubular wrapper having a lower end journal 1 for plugging into an upper aperture in a core supporting structure 12, 13 and a spike bar 2 with an articulated bush 4 for engaging a lower aperture in the structure 12, 13. The bush 4 is retained on a spherical end portion 3 of the spike bar 2 by a pair of parallel tubular retaining pins 6 disposed one each side of the bar 2, the pins 6 being collapsible at a predetermined loading to enable the spherical end portion 3 to pass between them. The centres of the upper and lower apertures are off-set and the axis of the lower aperture is inclined towards the vertical axis of the upper aperture so that the fuel element sub-assembly is tilted towards a structural member (not shown) which upstands from the core supporting structure 12, 13. On withdrawal of the sub-assembly from the core, in the event that the side thrust on the spike bush 4 (caused by the off-set apertures) induces the bush to jam, excessive withdrawal loads are avoided because the tubular retaining pins 6 collapse to allow the spherical end portion 3 to pass between them. The sub-assembly is then withdrawn without the spike bush 4 but this can be retrieved subsequently by a simple grab engaging a groove 10, the side thrust on the bush being removed by withdrawal of the spike bar 2.
Patent GB-660002-A (GB)
Title: Improvements relating to the glazing and embossing of textile fabrics
IPC: D06M15/423
Filed: 1948-05-21
Abstract: Textile fabrics are impregnated with an aqueous solution of a precondensate of bisurea and formaldehyde or a formaldehyde-yielding substance, dried or partially dried, subjected to the mechanical treatment necessary to give a glazed and embossed effect to the finished fabric, and heated, e.g. at 150-175 DEG  C. for a short time, to carry the condensation of the bis-urea and formaldehyde to the insoluble stage.  The process is said to be particularly applicable to fabrics of cellulosic materials such as cotton and when performed in conjunction with hot friction calendering.  The aqueous solution of the precondensate is preferably applied in the presence of an acid catalyst such as ammonium dihydrogen phosphate and the solution may also contain thermally decomposable quaternary ammonium salts such as stearamido-methylpyridinium chloride.  In an example, 24 parts of a paste formed by heating with stirring 326 parts of a 37 per cent aqueous solution of formaldehyde, 115 parts of bis-urea and a small proportion of caustic soda are diluted with 76 parts of warm water to which has been added 0.45 parts of ammonium dihydrogen phosphate.  A piece of printed cotton fabric is impregnated with the solution, partially dried, calendered with friction twice on one side only at 150 DEG  C. and baked for 3 minutes at 150 DEG  C.  Excess resin and catalyst are then removed by washing the fabric in a warm dilute solution of soap and soda ash.  The glazed effect produced is said to be substantially unaffected by subsequent laundering. Specifications 424,076, 425,032 and 441,038 are referred to.
Patent GB-807803-A (GB)
Title: Improvements in or relating to a method of extracting deuterium from hydrogen-containing gases
Inventor: ROBERTS NEVILLE WYN
IPC: B01D59/32
Filed: 1956-05-04
Abstract: Deuterium is extracted from hydrogen-containing gases by subjecting the gases to a countercurrent catalytic exchange with liquid ammonia to transfer the major part of the deuterium content to the ammonia, distilling the deuterium enriched ammonia into two fractions and withdrawing the fraction having the higher deuterium content.  A catalyst, which may be dissolved in liquid ammonia, may be used, e.g. potassium amide.  The catalyst may be formed in situ by using a solution of an alkali metal in liquid ammonia, which solution also contains a salt of a metal, such as iron or titanium, capable of existing in more than one state of oxidation, e.g. ferric sulphate. Alternatively, a solid catalyst, e.g. chromium, platinum, nickel, palladium or vanadium, which may be on a carrier may be used. Ammonia may be evaporated into the gas before exchange.  As described, ammonia synthesis gas (N2 + H2) is passed through a converter containing a nickel catalyst to convert CO and CO2 to CH4. The purified gas, after heat exchange with effluent gases, is passed through an ammonia producer where 10 per cent of the gases are converted to NH3, which, after cooling, is condensed and separated. The remaining gases are passed to the base of a first catalytic exchange tower where they are scrubbed with liquid NH3 containing KNH2.  The ammonia condensed from the gases is passed to the upper part of the tower.  The gases pass from the scrubber to the ammonia plant.  The deuterium-enriched NH3 from the first exchange tower passes to a second catalytic exchange tower where it is used to scrub N2 + H2 gases produced by decomposing part of the liquid NH3 leaving the second tower.  Residual gases from the second tower are passed back to the base of the first tower.  The remaining liquid NH3 from the second tower is reduced to atmospheric pressure and the KNH2 is recovered for return to the first tower feed.  The liquid NH3 passes to the distillation column whence NH3 of the same isotopic ratio as that supplied to the scrubber is recovered above and deuterium-enriched liquid ammonia is recovered below.  The distillation column is below ambient temperature and is provided with a separate vapour recompression system equipped with two indirect heat exchangers to provide partial condensation of the top fraction for reflux, and partial boil up of the bottom fraction.  The deuterium-rich fraction may be burned to form heavy water.

Title: Method of producing gases with controlled concentrations of water vapour
IPC: B01F23/10
Filed: 1970-03-23
Abstract: 1309098 Humidifying gases AIR PRODUCTS & CHEMICALS Inc 23 March 1970 [1 April 1969] 13895/70 Heading B1R Dry carrier gas is humidified by mixing it with dry hydrogen and then oxidising the hydrogen in the stream to produce the required quantity of entrained water. The oxidation may be achieved by also adding dry oxygen to the gas stream, usually in amounts stoichiometric with respect to the hydrogen, and then catalytically converting the mixture to water, or by passing the carrier gas and hydrogen over an oxidising agent such as cupric oxide to convert the hydrogen to water, or, in suitable cases where the carrier gas is readable with hydrogen (e.g. N 2 O), by reacting it catalytically with the hydrogen. When oxygen itself is present, either the oxygen or hydrogen may if desired be present in excess. Where hydrogen is present in excess, the stream may then be passed over cupric oxide to convert the excess hydrogen to water. The invention is stated to be of particular application for spacecraft life-support systems.

Abstract: 1413453 Cable tensioning devices WESTINGHOUSE ELECTRIC CORP 29 March 1974 [4 April 1973] 13930/74 Heading B8B [Also in Division F2] A crane (3) which is mounted on the deck of a ship (1) comprises a boom (9) which is raised and lowered by means of a cable (15) wound on a drum (13) and a load lifting cable (23) which extends from a motor-driven hoist drum (7) and passes about a sheave (17) at the upper end of the boom (9) and then passes about a sheave 21 mounted on the piston-rod 37 of a ram (19) which is used to maintain a predetermined tension in the cable (23) during raising and lowering of a load (25), the cable (23) passing from the sheave 21 back to a second sheave (17) at the upper end of the boom (9) and then passing vertically downwardly to the load (25), Fig. 1 (not shown). The ram (19) is shown in Fig. 3 and consists of a housing 31 in which a first piston 33 is displaceable, the piston 33 dividing the housing 31 into chambers 39, 47, there being a piston-rod 37 extending from the piston 33 which carries the sheave 21, and a second piston 35 is located for movement between the end of the housing 31 and the first piston 33. A cylinder of pressurized gas 71 is connected by a conduit 73 to a gas inlet port 53 in the housing 31 and an adjustable pressure regulating valve 75 in the conduit 73 is adjusted to a predetermined pressure depending on the load to be lifted, and on opening a valve 77 in the conduit 73 pressurized gas is admitted to the chamber 39 and passes through openings 49 in the piston 33 to the chamber 47, the gas reacting on the piston 33 so that as a load is lifted through the water the pressurized gas absorbs shock and moves the piston 33, and thus the piston-rod 37 and sheave 21 in and out to pay out and take up the cable 23 thus keeping a generally constant tension in the cable 23. The volume of gaseous fluid in the system can be altered by means of an expansion chamber 85 which is connected to, and is filled by, the gas cylinder 71 simultaneously with the supply of gas to the chambers 39, 47. After the load has been lifted from the water additional lifting capacity is required due to the loss of buoyancy and by admitting hydraulic fluid from a reservoir 61 through an hydraulic control valve 67 and through a fluid inlet port 51 into a chamber 45 defined by the housing 31 and a second floating piston 35, the said piston 35 is moved towards the piston 33 to cause extension of the piston-rod 37, thereby raising the load. During this latter mode of operation the hoist drum (7) may be locked to prevent the paying out of the cable (23).

Title: Improvements in or relating to electric discharge tubes
Inventor: BECK ARNOLD HUGH WILLIAM
IPC: H01J17/48
Filed: 1953-05-19
Abstract: 745,931. Multi-gap cold-cathode tubes. STANDARD TELEPHONES & CABLES, Ltd. May 19, 1953, No. 14016/53. Class 39 (1). [Also in Group XIX] A cold-cathode gasfilled discharge tube has electrodes defining discharge gaps positioned in ionization coupling relationship in at least two alternative cyclic sequences. The numbers of gaps in the alternative sequences may be different. The cathode assembly shown comprises storage cathodes 1 to 9 together with intermediate transfer cathodes mounted in the arc of a circle on an insulator 26, a metal screen 27 being inserted between cathodes 9 and 1 to prevent direct coupling between them. Storage cathodes 10b, 11 and 12, their intermediate transfer cathodes and transfer cathodes 16 and 18 are mounted in a reentrant loop connecting cathodes 9 and 1. Cathode 10a is positioned so that both cathodes 10a and 10b are in ionization coupling relationship with transfer cathode 16. The cathodes are all of the directional type described in Specification 740,838 and comprise a discshaped head and a wire tail projecting therefrom, with the exception of transfer cathode 18 which has two tails. At the expense of introducing an additional cathode, the plural-tailed cathode may be a storage cathode, in which case the transfer cathodes can be non-directional, the storage cathodes alone being directional. The cathode assembly is mounted in a tube, as described in Specification 740,838, which is operated by applying voltage pulses to all the transfer electrodes in common as described in Specification 692,415. The discharge is stepped from cathode 1 to cathode 9 and then returns to cathode 1 via cathode 10a or via cathodes 10b, 11 and 12 in accordance with external strapping or switching arrangements (see Group XIX). The tube can thus be operated with repetitive cycles of either ten or twelve pulses and an output signal obtained at the end of each cycle across a resistor connected either to cathode 10a or to cathode 12. By appropriate connections to the various cathodes the tube can also be used as a dividing mechanism providing an output on receipt of every 2, 3, 4, 5, 6, 10 or 12 input pulses. A tube having two alternative sequences with equal or unequal numbers of gaps can be used to provide alternative outputs selected by means of a switch or relay connected to the tube. Specification 704,968 also is referred to.
