Inventor: LEE NORMAN
IPC: F16L27/10
Filed: 1961-08-16
Abstract: 959,700. Pipe couplings. KEELAVITE HYDRAULICS Ltd. July 30, 1962 [Aug. 16, 1961], No. 29617/61. Heading F2G. A fluid-tight coupling assembly for connecting tubular conduit members 1, 2 includes two coaxial sleeves 5, 6 having adjacent transverse faces 5a, 6a separated by a sealing ring 8 lying in a groove 7 in one of the faces. The other ends of the sleeves co-operate with the conduit members to provide recesses to contain further sealing rings 10, 16 arranged such that the surface area of the coupling members on which the fluid pressure acts is greater where the rings 10, 16 are situated than where the central ring 8 is situated so that there is a continual force pressing the coupling members together. The threaded shoulder of conduit member 2 ensures that ring 10 is not axially compressed by coupling member 6 and engages with connecting member 24. The packing ring 8 of L-shape limits the compression of ring 16. A contractible tapered collet 20 engaged by the tapered end of connecting member 24 maintains the two conduit members coaxial and can draw member 1 into position.

Filed: 1970-06-18
Abstract: 1318972 Refining metals SALZGITTER HUTTENWERK A G 18 June 1970 [18 June 1969] 29678/70 Heading C7D [Also in Division F4] Metal is continuously refined by top blowing with refining gas in two stages after each of which the metal is separated from its accompanying slag. Fresh slag is produced in the second refining stage and, after separation from the fully refined metal, passes under gravity to the beginning of the first stage which it enters above the liquid level in the first stage. As shown in Fig.1 metal such as molten pig iron enters first refining chamber 1a through inlet 5 and is top blown with oxygen. Slag and metal flow along a slagmetal separation channel 2a at the end of which slag is removed through channel 11a while partially refined metal flows through a trap system over a weir 4 and into second refining chamber 1b where it is blown with oxygen containing lime dust and possibly fine ore. Fully refined metal and freshly formed slag flow along channel 2b and are separated, metal leaving the apparatus via a trap system and channel 13 while the slag flows over weir 14 into the first refining vessel 1a
Patent GB-747661-A (GB)
Title: Production of thionophosphorus compounds
IPC: C07F9/42
Filed: 1952-11-24
Abstract: The invention comprises (1) the preparation of alkaryl thionophosphonyl halides by sulphurizing alkaryl halophosphines in the presence of a polyvalent metal halide catalyst and hydrolysing the products; (2) alkaryl thionophosphonyl halides which contain an alkyl group of at least 10 carbon atoms; (3) the esters and metal salts of the acids corresponding to (2) prepared by replacement of the halogen with hydroxy and simultaneous ester- or saltformation; and (4) the free acids corresponding to (2) prepared by treating their metal salts with mineral acids. The alkaryl halophosphine is preferably obtained in situ by reacting an alkyl substituted aromatic hydrocarbon with a phosphorus halide in the presence of the polyvalent metal halide (e.g. aluminium chloride), using 0.8-1.5 mols. of the latter per mol. of aromatic hydrocarbon.  Sulphurization may be effected with elementary sulphur, sulphur chloride or a phosphorus-containing compound such as phosphorus sulphide or thiophosphoryl chloride. The reaction is preferably carried out at 0-90 DEG  C. using an amount of sulphurizing agent sufficient to provide 1-3 atoms of sulphur per mol. of alkaryl halophosphine. Hydrolysis of the metal halide complex to give the free alkaryl thionophosphonyl halide is effected by pouring the reaction mixture on to ice or water.  The aluminium chloride may be replaced by ferric chloride, zinc chloride or boron trifluoride.  In the examples: (1) toluene thionophosphonyl dichloride is obtained from toluene, phosphorus trichloride, thiophosphoryl chloride and aluminium chloride; similar products are made from m-xylene, ethylbenzene and cumene; (2) as in (1) using sulphur instead of thiophosphoryl chloride; (3) as in (2) using a waxsubstituted benzene as starting material; (4) as in (3) using sulphur monochloride as sulphurizing agent; a wax-substituted benzenephosphonic acid is a by-product, from hydrolysis of the alkaryl-tetrachlorophosphorane RPCl4; (5) by using less sulphur than in (3) di-(wax-substituted benzene) thionophosphonyl monochloride is obtained; (6) as in (3) using dodecylbenzene as starting material; (7) as in (3) the starting material being made in situ from benzene, chlorinated wax and aluminium chloride; (8) potassium wax-substituted benzenethionophosphonate is prepared by hydrolysing the dichloride with potassium hydroxide in isopropanol; (9) the free acid corresponding to (8) is made from the salt and hydrochloric acid; (9) a solution of the zinc salt of wax-substituted benzenethionophosphonic acid in mineral oil is prepared by reacting the dichloride with zinc oxide in mineral oil containing a little water; (10) the dibutyl ester of wax-substituted benzene-thiophosphonic acid is obtained from the dichloride and n-butanol in pyridine.  In general the alkyl substituent in the aromatic residue may contain up to 30 carbon atoms.  Other non-hydrocarbon substituents may be present or may be introduced into the thionophosphonyl halides, e.g. by nitration, chlorination or sulphonation.

Title: Improvements in and relating to machines for applying solder to can bodies or the like
IPC: B23K1/16
Filed: 1936-11-02
Abstract: 483,750. Soldering can bodies. FAR RER, J. O. (Continental Can Co., Inc.) Nov. 2, 1936, No. 29830. [Class 83 (iv)] In applying solder to the side seams of can bodies, the bodies are fed lengthwise along a roll rotating in a solder bath, the roll having one or more sections provided with a helical rib disposed relatively to the direction of rotation so as to distribute the solder along the seam and strip surplus solder therefrom. The bodies 8 are fed by a chain 12 over a solder applying roller rotated in a bath 2 of solder. The roller comprises a number of solid sections, each having a central cylindrical portion 7 and two tapered portions'6 so as to conform to the shape of the body which is concaved due to heating, and also one or more sections comprising flat-edged helical ribs 15 with substantially vertical forward faces 17 and inclined rear faces 18, so that solder applied to the seam is fed back thereby to distribute it over the seam and so as to remove surplus solder. The ribbed portions, which may be in the form of hardened steel sleeves fitted over the roller, may be tapered on the feed side or on both sides of its central portion, which may be of diameter greater than that of the solid sections. The bodies after passing over the solder roller are passed over a rotary wiper roller 20. The use of the ribbed section is stated to reduce the amount of surplus solder removed by the wiper, and so to prevent throwing of solder into the interior of the bodies during their passage through the machine.

Title: Process for the recovery of heavy hydrogen and heavy water
IPC: F25J3/02
Filed: 1955-10-19
Abstract: <PICT:0815098/III/1> In a process for recovering deuterium from natural water, continuously supplied to the process, by catalytic exchange transfer from water vapour to hydrogen and subsequent rectification of the deuterium-enriched hydrogen, wherein the hydrogen top product from the rectification is continuously recycled through a saturator, wherein the hydrogen takes up water vapour, a reactor, wherein the catalytic exchange of deuterium takes place, and a condenser, wherein water, which has become poor in deuterium, is removed and then back into the rectification column, after cooling to the required low temperture by heat exchange with the cold hydrogen leaving the top of the column and expansion, the gas pressure at the commencement of the expansion is attained by compression in two stages in the hydrogen circuit, one prior to the taking up of water vapour, and the other between the catalytic exchange reactor and the condenser, in such a way that the pressure during the taking up of the water vapour is 40-85 per cent of the final pressure attained by the second stage compression, and heat released in the condenser is transferred continuously to water which is fed into the saturator. Hydrogen enters the base of column 45 of which the lower part is a saturator and the upper part has alternate layers of catalyst and bubble plates containing water, and in which hot water is circulated by pump 9, while fresh water is supplied continuously at 10.  The hydrogenation catalyst layers may be Pt on Al2O3, or Ni on Cr2O3, to effect exchange HDO + H2 --> H2O + HD.  The hydrogen-water vapour mixture passes from column 45 through heat exchanger 19, to heater 14, and the mixture at 500-600 DEG  C. passes through catalyst reactor 25, heat exchanger 19 and compressor 3a, where the pressure is increased to say 20 atmospheres, to condenser 6.  The condensate is circulated through condenser 6 by pump 12 and passes in heat exchange relation with the water circulating in saturator 45 in 13 and the condensate exchanges heat with the fresh water in 20.  The deuterium-enriched hydrogen from condenser 6 passes through drier 7, heat exchanger 2 in countercurrent to cold hydrogen and expansion apparatus 8 to rectifier 1.  The deuterium-rich fraction is withdrawn at 15 and hydrogen is returned through heat exchanger 2 and compressor 3, where the pressure is increased to say 15 atms. to saturator 45.  A heating spiral may be provided below each catalyst layer, and the deuterium-rich fraction may be further concentrated and burned with oxygen, wholly, or in part, to heavy water.  In Figs. 2 and 3 (not shown) alternative arrangements for thermally coupling the saturator and condenser columns are shown.  In the first, several circulating currents of water are branched off from each column through heat exchangers, and in the second direct transfer of water takes place where hot water flows from condenser to saturator and cooled water is returned.

Filed: 1962-08-03
Abstract: 1,062,621. Electro-physical measurements. IMPERIAL CHEMICAL INDUSTRIES Ltd. Aug.2, 1963 [Aug. 3, 1962], No. 29911/62. Heading G1N. The condition of bulk stored material e.g. fertiliser in a silo is signalled by a radio-capsule buried therein and having transducers responsive to e.g. pressure, temperature and humidity. As described the apparatus includes plates 2 for measuring conductivity, telescopic arms connected to a potentiometer 6 for measuring the shrinkage and a thermistor for measuring temperature. The apparatus is switched on by means of a radio signal which controls a motor to operate in sequence switches which enable the measurements to be made and the results transmitted to an external receiver. The voltage analogues produced in turn by the measuring circuits of Fig. 3 (not shown), modulate the frequency of the blocking oscillator. The output of this oscillator is then shaped and frequency divided by the bi-stable circuit whose outputs are amplified and used to supply an aerial suppressor loop and to modulate the frequency or amplitude of the transmitter stage Fig. 4 (not shown). The receiving circuit for the switching circuit may be made more frequency sensitive by including a crystal in the aerial circuit. The motor operated switches may also be replaced by a uniselector in which case a pulse must be transmitted to change from one stage in the measuring cycle to the next. To prevent the initial settling of the material affecting the shrinkage transducer this includes a locking device for the telescopic tubes which is released by melting a nylon monofilament by means of an electrical heater. The final circuitry may produce a voltage analogue of the blocking oscillator signal and count the pulses in a certain interval to give a digital reading. The conductivity measuring circuit includes a high frequency oscillator connected across the material the current passing being detected and amplified by a transistor to produce a voltage analogue.

In a hydrostatic transmission for a road vehicle the accelerator pedal controls the pressure in an auxiliary hydraulic circuit including a throttle valve regulating the pump delivery. As shown, a pump 2 driven by the engine 1 supplies motors 4, 4a driving the wheels 5, 5a, the supply lines 6, 7 being connected to a selector valve 41 by a line 14. The engine also drives an auxiliary pump 18 whose output passes by a line 19a to a throttle valve 17 controlled by the accelerator pedal 12, and by a line 19b to a further throttle valve 16 and to the selector valve 41. Valves 16, 41 are connected by a line 15. Outlet lines 29, 32 from valve 41 act on a piston 30 operating a delivery control member 28 for the main pump 2 through a rod 35 and lever 36. In the neutral setting shown, member 28 is set for zero delivery, while the auxiliary pump 18 delivers to exhaust through valve 17. Upon moving valve 41 to the left for forward drive the main lines 6, 7 are by-passed to exhaust through lines 14, 15 and valve 16, and communication opened between line 19b and piston 30. As pedal 12 is depressed valve 17 is progressively closed to increase the pressure in the auxiliary circuit and so move valve 16 by a piston 24 to cut off the main lines 6, 7 from exhaust, while piston 30 is operated to render control member 28 effective to regulate the delivery of pump 2.
