Patent GB-198188-A (GB)
Title: Improvements in and relating to tight joints for receptacles having a high vacuum
IPC: H01J5/30
Filed: 1922-05-01
Abstract: 198,188. Dunoyer, L. D. J. A. May 1, 1922. Joint-making packing.-A vacuum-tight joint, particularly for sealing-in the electrodes of mercury-vapour rectifiers having metal receptacles, is formed by applying to the two joint surfaces a substance that is fluid at the time of application but is capable of irreversible transformation into a solid, for example by polymerization, this transformation being completed after the coated surfaces have been united by high pressure. Suitable substances are bodies of the class of aceto-celluloses or bakelites (phenols condensed or polymerized). Each of the surfaces to be joined is coated to a thickness of several millimetres and the temperature is gradually raised, say to 100‹ C., so as to bring about polymerization without ebullition occurring. When the substance has acquired an elasticity resembling that of rubber, the surfaces of the joint are placed together and submitted to strong pressure. The heating is then continued to obtain complete polymerization. The whole is then allowed to cool, the joint assuming a permanent solid state. The material may be an insulating-substance when two metal surfaces are to be joined, but this is not necessary when metal is joined to glass, porcelain or other insulator.

Title: Improvements in and relating to the production of choline compounds
Filed: 1932-04-28
Abstract: Carbonates of choline and its homologues and substitution products, i.e. of quaternary ammonium bases with at least one hydroxyalkyl group, are manufactured by reacting tertiary organic bases with alkylene oxides in the presence of water and carbonic acid.  The tertiary bases employed may be aliphatic, aromatic, hydroaromatic, heterocyclic or mixed tertiary nitrogen bases, e.g. trimethylamine, triethanolamine, triphenylamine, dimethylaniline, pyridine and quinoline.  From the carbonates, the corresponding salts of other acids can be obtained by simple reaction with evolution of carbon dioxide.  The acids which may be employed include halogen hydracids, sulphuric acid, cyanic acid, thiocyanic acid, aliphatic or aromatic acids, e.g. fatty acids, or the sulphonation products of these acids, e.g. sulpho-fatty or sulpho-aromatic acids.  In some cases increased temperature is advantageous for this reaction.  The products are useful as the basis for pharmaceutical and cosmetic salves, in the leather industry, and in the textile industry as additives for dyeing and sizing baths in consequence of their wetting properties.  In examples: (1) ethylene oxide and carbonic acid are introduced into an aqueous solution of trimethylamine, yielding a solution of choline carbonate from which the salt may be obtained by evaporation; (2) ethylene oxide is passed into a solution of triethanolamine saturated with carbonic acid, producing a solution of tetraethanolammonium bicarbonate; (3) an aqueous solution of propylene oxide is added to an aqueous solution of pyridine with simultaneous introduction of carbonic acid, yielding a solution of an oxypropylpyridinium bicarbonate; (4) ethylene oxide and carbonic acid are introduced into an aqueous solution of quinoline to produce oxyethylquinolinium bicarbonate; (5) the solution obtained in (1) is decomposed with thiocyanic acid yielding choline thiocyanate; (6) the product of (2) is decomposed with salicylic acid to produce tetraethanolammonium salicylate; (7) a solution of oxyethylpyridinium bicarbonate (obtained by a process analogous to that of (2)) is decomposed with oleic acid producing the corresponding oleate; (8) dry trimethylethanolammonium carbonate is dissolved in amyl alcohol or xylene and heated with oleic acid.

Filed: 1929-04-22
Abstract: 324,587. Hoffmann Manufacturing Co., Ltd., and Smith, C. H. April 22, 1929. Grant of Patent refused. Securing sleeves, collars, ball-races, and the like on shafts.-Sleeves or collars, such as ball races for bearings, are secured on shafts by split conical sleeves C, C<1> which are forced into the conical bores of the collars or inner races A, A<1> by the unscrewing of a nut E engaging a threaded cylindrical portion D of the sleeve C and bearing against the sleeve C<1>. Lateral movement of the races is prevented by abutments which may comprise a split spring ring or a divided collar G engaging a circumferential groove, and a collar F engaging a shoulder on the shaft. Additional races such as I may also be secured. The nut E may be used for withdrawing the sleeve C and may then be reversed for withdrawal of the sleeve C<1>. In a modification, the sleeves are threaded with opposite hands and the nut engages both sleeves so that rotation in one direction tightens the sleeves and opposite rotation withdraws them. In a simpler form for securing a single race, the nut may bear against a fixed abutment e.g. a shoulder on the shaft.

Abstract: 1,115,223. Washing and filling casks. G. C. DOW. 2 June, 1965 [24 March, 1964], No. 12492/64. Heading B8T. A device for washing and filling a cask 4 whilst inverted and provided with a normally closed valve 6 in a casing 1, comprises a cylindrical member 15 with a tubular outlet 16, a tubular inlet 17 fed by a tube 19, and a sealing ring 22. When the device is applied to an inverted cask the sealing ring engages the cask neck and the valve 6 is opened by the inlet 17, and when washing liquid is supplied to the tube 19 it flows through ports 12 in a tube 10 extending to near the cask base, and leaves the cask via ports 14 in the casing 1 and passes to the outlet 16 via apertures 24. One form of washing apparatus comprises a rotary table, Fig. 4 (not shown), divided into four sections each having four apertures 27 receiving casks which are held by clamps 31, Fig. 3 (not shown), secured to an arm 30. The sections are used respectively for loading and unloading, an initial internal rinse, an internal and external detergent wash, and a final internal rinse. In each of the three treatment sections four devices are provided, each attached by an extension 18 to a pneumatic cylinder which brings the device into, and removes it from, engagement with a cask. Draining of washing liquid may be assisted by a gas blast fed through the inlet 17. In an alternative apparatus the casks are carried on an endless conveyer comprising centrally apertured cask carrying plates 34, Figs. 5, 6 (not shown), resiliently mounted by springs on a transversely spaced pair of endless chains 35. Each chain is driven by a plate 44 having rollers engaging a pair of rails 47, and a spring-urged ratchet arm 43 on the plate comes into engagement with one of a number of spaced extensions 42 on the chain. Each plate is attached by a pivotally mounted drive arm 48 to an endless chain 49 driven by a motor, not shown. In operation, the plates 44 are reciprocated on their rails 47 and thereby drive the chains intermittently and carry the casks from a loading section to a washing section, and at the latter a ram forces a pressure plate downwardly on to the base of the casks, whereby the cask carrying plates 34 are depressed. The washing devices come into contact with the cask inlets. An inverted cask may be filled with beer by the device by feeding the beer through the outlet 16, and overflow from the cask passes through the tube 10 to the inlet 17.

Title: Improvements in or relating to induction heating
IPC: H05B6/04
Filed: 1953-05-06
Abstract: 724,480. Induction heating. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. May 6, 1953 [June 26, 1952], No. 12572/53. Class 39 (3), An induction heating system comprises an oscillator having a tank circuit embodying an inductor through which a magnetic material to be heated passes, power amplifier means having its input circuit coupled to draw power from said oscillator, and a second inductor through which the magnetic material passes, in the output circuit of the power amplifier. Travelling steel strip 1 passes through an inductor 2 in the tank circuit of an oscillator 5, and also through inductors 3, 4 energized from power amplifiers 6, 7 respectively. The amplifier input circuits are coupled to draw power from the oscillator, and are fed with D.C. bias voltage from sources 11 and 12 which are regulated in voltage by a regulator 16 operatively connected to a temperature responsive device 14. The arrangement is such that when the strip reaches a predetermined temperature the device 14 acts through the regulator 16 to set the bias voltages of the amplifiers at such values that the strip is maintained at that temperature. Power supplies 8 and 9 feed the oscillator and amplifiers. More particularly, the oscillator is supplied. from conductors 23, 25, Fig. 2, and has triodes 21, 22 and a tank circuit comprising the heating inductor 2, capacitors 26-28 and an adjustable inductor 29. Its power output is adjusted by rheostats 35, 36, or by varying the cathode heating current. The latter is fed through a saturable core reactor 37 having a winding 38 the current in which may be varied. A further control of the oscillator output is provided by a second saturating winding 41 shunted by a variable resistor 39. The power amplifier 6 includes triodes 51, 52, 55, 56, and a tank circuit comprising heating inductor 3, adjustable inductors 57, 58, and capacitors 59, 59A. The amplifier 7 includes triodes 61-68 and tank circuit comprising heating inductor 4; adjustable inductors 75-78 and capacitors 81-84. Leads 42, 43 are connected as shown from the oscillator circuit to the grids of the amplifier triodes, and causes the circulation in the amplifier tank circuits of amplified current at the oscillator frequency.. A D.C. bias voltage is applied to the grids of triodes 51, 52, 55,.56, by the D.C. generator H. which is also connected to the variable resistor 39 and the winding 41. The generator 11 has two field windings, one connected to a D.C. source and the other to the regulator 16. When the strip temperature rises above the desired value the generator voltage is increased to reduce the amplifier tank currents. A fall in the strip temperature has the opposite effect. Similarly, the D.C. source 12 has -one pole connected to the grids of the triodes of the amplifier 7, and the bias voltage thereof is automatically controlled in the same way. Specification 575,424, [Group XXXV], is referred to.

Title: Missile security mechanism
IPC: F42C15/24
Filed: 1977-03-25
Abstract: 1518074 Fuze safety mechanism MEFINA SA 25 March 1977 [6 April 1976] 12742/77 Heading F3A A missile safety mechanism is constructed to preclude inadvertent disablement which could lead to the missile firing during handling. The mechanism comprises a rod 8 slidably axially and biased by a spring 22 in a direction towards a socket 11. The latter surrounds the rod 8 at one end and carries hooks 12 normally engaged in a first groove 9 in the rod 8. An inertia block 13 has a sleeve portion which normally surrounds the hooks 12 to retain them in the first groove 9; the block 13 is biased towards the socket 11 by a spring 14. The mechanism so far described is known and can be disabled inadvertently if the missile is dropped during handling. To preclude this, a retaining member is provided normally to block movement of the rod 8 towards the socket 11 under the action of the first-mentioned spring 22. As described, the retaining member is a pivoted pawl 18 biased by a spring 20 into the path of movement of the rod 8 and abutted by a shoulder 15 on the rod 8. The pawl 18 has a ramp surface 21. In operation, when the missile is fired, the inertia block 13 moves against the action of the second-mentioned spring 14 so releasing the hooks 12 from the first groove 9. Similarly, the socket 11 moves relative to the rod 8 so that the hooks 12 engage (and, by action of the inertia block 13, become locked in) a second groove 10 on the rod 8. Movement of the inertia block 13 displaces the pawl 18 to a retracted position whereupon the rod 8 moves under the action of the first-mentioned spring 22 so that an end pin 7 is withdrawn from a slider 5. The latter is then displaced by a spring 6 and releases a firing pin 4. In a modification, the pawl 18 is replaced by a radial locking pin; also, the pawl/locking pin can be caused to retract other than by the inertia block 13.
