IPC: C08L63/00
Filed: 1951-05-09
Abstract: Compounds containing epoxy groups are polymerized in presence of an ion-exchange resin containing a plurality of sulphonic acid groups. Epoxy compounds mentioned are diglycidyl ethers of dihydric phenols; mixed ethers of dihydric phenols, e.g. the glycidyl allyl ether of bisphenol; glycidyl acetate; diglycidyl phthalate; ethylene oxide; propylene oxide; 3,4-epoxy butyl-, 2,3-epoxy butyl-, or 2,3-epoxy-2-methyl-propyl-derivatives of polyhydric phenols; epoxy containing phenol aldehyde condensates as described in Specifications 721,149 and 721,151; glycidyl or epoxyalkyl derivatives of phenol, cresols, xylenols, naphthols, t-butyl phenols, styryl phenols, or hydroxy diphenyl; styrene oxide; vinyl cyclohexene dioxide; butadiene oxide.  Ion-exchange resins mentioned are sulphonated styrene-divinyl benzene copolymers; sulphonated phenol aldehyde condensates, including those from alkyl phenols or polyhydric phenols; sulphonated coal; sulphonated tannin-formaldehyde resins; phenol-formaldehyde resins containing omega-sulphonic acid residues.  The reaction may proceed at room temperature or with heating to 100-150 DEG  C. Removal of heat is necessary in case of exothermic reactions. The amount of ion exchange resin may be catalytic, e.g. 0.5 per cent, or even less, of the epoxy compound, or amounts up to 50 per cent by weight of the epoxy resin may be employed.  Other known catalysts for epoxy compounds, e.g. amines such as diethyl amine, trimethyl amine or butyl amine may be used together with the ion exchange resins. The products may be moulded and worked mechanically.  Fillers, e.g. asbestos or wood flour, plasticizers, dyes and lubricants may be incorporated.  By addition of solvents, plasticizers or drying oils, adhesives or coating compositions may be produced.  In example I sulphonated styrene-divinyl benzene copolymer is heated at 120 DEG C. for 1 hour and then at 170 DEG  C. for 30 minutes with the diglycidyl ether of p,p1 - dihydroxydiphenyldimethylmethane.  II. Sulphonated phenol-formaldehyde resin is heated at 120 DEG  C. for 1 hour with the diglycidyl ether of resorcinol.

Title: Manufacture of tri-ªÐ-anisyl-bromoethylene
Filed: 1942-08-12
Abstract: 559,374. Tri-p-anisyl bromoethylene. BASFORD, F. R., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Aug. 12, 1942, No. 11273. [Class 2 (iii)] Tri-p-anisyl-bromoethylene is prepared by treating tri-p-anisyl ethanol with bromine in approximately equimolecular amounts in the presence of an organic solvent which is subsequently removed. The reaction and the removal of the organic solvent are carried out under conditions which preclude prolonged contact of the hydrogen bromide formed in the reaction with the other reactants at temperatures above 100‹ C. The reaction is preferably carried out at room temperature, and the solvent removed under reduced pressure but if desired a solvent which combines with the hydrogen bromide such as pyridine may be used. Alternatively a material such as sodium carbonate may be present. In these latter cases higher reaction temperatures may be used. The amount of bromine used may be a slight excess over the theoretical but such excess should not exceed 5 per cent. In examples: (1) A glacial acetic acid solution of bromine is added to a glacial acetic acid solution of tri-p-anisyl ethanol, the temperature being maintained below 25‹ C. during the reaction and the removal of the solvent. (2) Bromine is added to a solution of tri-p-anisyl ethanol in chloroform the temperature being adjusted as in example (1). Finally the reaction solution is boiled for a short time. (3) A chlorbenzene solution of bromine is added to a chlorbenzene solution of tri-p-anisyl ethanol at 20-25‹ C. After standing, the solution is boiled a short time and the solvent removed in vacuo. (4) A nitrobenzene solution of bromine is added to a solution of tri-p-anisyl ethanol in nitrobenzene and maintained at 20-25‹ C. After 16 hours the nitrobenzene is removed by distillation in steam. (5) A solution of bromine in nitrobenzene is added to a nitrobenzene solution of tri-p-anisyl ethanol at 20-25‹ C. After standing soda ash is added and the mixture refluxed. The solvent is finally removed by steam distillation. In each of the above examples the product is tri-panisyl-bromoethylene. This material is stated to have oestrogenic properties. Specification 549,200 is referred to.

Title: Improvements in vapourizing liquefied gases
IPC: F17C9/02
Filed: 1955-04-19
Abstract: 768,785. Liquid oxygen vaporizing apparatus. BENDIX AVIATION CORPORATION. April 19, 1955 [April 22, 1954], No. 11284/55. Class 8(2) Apparatus for vaporizing liquified gas, e.g. oxygen and dispensing it at a pressure above that at which the liquid is stored comprises an evaporator 31 supplied with liquid oxygen from a container 10 which is itself automatically supplied with liquid oxygen from a store 52 whenever the pressure in container 10 falls below a predetermined value. In normal operation liquid oxygen from container 10 and at a pressure of between 200 and 400 p.s.i. traverses openings 13 in an outlet nozzle 12, a duct 24 and an inlet 30 of the vaporizing coil 31 from the outlet 33 of which oxygen vapour passes to a pipe 34 and through a control valve 36 which opens automatically at a pressure greater than. 300 p.s.i. and then to a dispensing duct 37, pressure reducing valves 39 and service connections 38. Pressure gains access to the space above the liquid in container 10 through a duct 48, a check valve 47, a pressure limiting valve 46 which closes automatically at 400 p.s.i., a duct 45 and an opening 15 at the container head. The latter has a second opening 16 connected to a duct 40 having a sealing valve 41 closed by pressure in duct 45 when the latter exceeds 200 p.s.i., a hand valve 42 and a vent valve 43 closed by pressure in duct 45 when it exceeds 85 p.s.i. When all the liquid oxygen from container 10 has been gasified the pressure drop closes valve 36 and opens valve 41 and connects container 10 to the store 52 through a check valve 50 and duct 51. On further reduction of pressure, valve 43 opens and vents container 10 to atmosphere, whereupon liquid oxygen flows from store 52 through a check valve 26, a jet 27, the duct 24 and apertures 13 of nozzle 12 to the container 10; direct access of liquid from store 52 to coil 31 being prevented by the aspirating action of the jet 27. Filling is completed when a float 19 is seated at 18.

Title: Improvements in infinitely variable friction transmission gearing
IPC: F16H15/10
Filed: 1929-04-12
Abstract: 328,766. Shaw, H. S. Hele-, and Beacham, T. E. April 12, 1929. Variable-speed gearing comprises a disc a driving a roller b which is raised relatively to the roller to change speed, whereupon the roller is advanced on a spiral track by power, such precessional motion of the roller, through a linkage e, &c., bringing the disc back automatically to symmetrical position. The disc a, which is driven through a universally-jointed shaft a<6>, Fig. 1, is supported in a frame d pivoted at d<6> on a dashpot d<8>. The frame d has two horns d', d<2>, Fig. 3, with bearings c<3>, e<8>, Fig. 2, which are above the axis of disc a. This eccentricity produces a wedging of the roller against the disc and frictional force proportional to load. The roller b is secured to an end shaft b<6> connected to a shaft b<2> by a universal joint permitting the roller to move freely in the plane of Fig. 2. This joint comprises a fork b<4> carrying two inwardly-directed rollers b', Fig. 1, free to move axially in grooves b<11> in an enlargement b<12> of the shaft b<2>. A tail-shaft b<16> is driven from shaft b<2> through a gear pair b", b<14>, Fig. 2, and a ratchet clutch b<15>. To effect a change of speed, a sleeve b<25> is turned by a lockable hand-wheel b<24>. A spindle b<23> feathered within that sleeve is turned, and a screwed part b<21> screws through a nut b<20> forming part of the carriage b<18> of the roller b, which is held from axial motion by friction with disc a. Spindle b<21> moves to the left bodily and tilts a lever e pivoted at e<1> so as to thrust downwards a rod e'. This depresses a lever e<5>, Fig. 3, which turns a pivot shaft e<9> and raises an eccentric e<7>, which turns in the eye of the frame-horn d<2>. The horn d<2> is raised so that the disc a is raised. The roller b then runs spirally upon the disc and slides axially, changing the speed by power. The carriage b<18> and nut b<20> carry screw b<21> bodily to the right of Fig. 2 so that lever e turns back, eccentric e' and horn d<2> are lowered, and disc a returns to symmetry on the new speed determined by the turn of the hand-wheel. A screw-wheel b<40>, Fig. 2, and pointer b<42> indicates the speed in use. The parallel motion of the carriage b<18> is assured by a bearing b<32>, Fig. 3, guided by perpendicular rollers b<33>, b<34>. Oil drips from a tray k, Fig. 1, upon the metal working friction parts.

Title: Gold tertiary alkyl mercaptides and method for the preparation thereof
IPC: C23C18/02
Filed: 1959-04-03
Abstract: The invention comprises gold tertiaryalkyl mercaptides of formula <FORM:0889912/IV (b)/1> where x, y and z are integers in the range of from 1 to 40.  They may be prepared by reacting the corresponding t-alkyl mercaptan with a gold salt auric or aurous such as an auric halide or a potassium haloaurate, e.g. at 0 DEG C.-100 DEG C. Alternatively, the mercaptan may be reacted with a C1-8 alkyl sulphide-aurous halide complex.  These complexes are prepared, preferably in situ, from the alkyl sulphide and an auric halide. Preferably methyl sulphide and gold liquor (the solution of auric chloride in hydrochloric acid obtained by dissolving gold in aqua regia and decomposing the nitric acid by repeated evaporation with HCl), are mixed in an aqueous medium between 0 DEG C. and 38 DEG C. and, without isolating the reaction product, the t-alkyl mercaptan is added promptly; excess alkyl sulphide is preferably used.  In another embodiment a solution of auric halide, such as gold liquor diluted with water, is added slowly to a mixture of t-alkyl mercaptan and the C1-8 alkyl sulphide; an organic solvent may be present.  The products are used in compositions for applying metalic gold to surfaces (see Groups II, VIII, XV, XVI and XXIII).  Specification 616,521 is referred to.ALSO:A gold decorating composition comprises a gold t-alkyl mercaptide of formula:-  <FORM:0889912/II/1> where x, y and z are integers from 1 to 40.  (For preparation see Group IV (b)). Solid or liquid diluents such as organic solvents, mercuric oxide or sulphur may be used.  The composition may contain a gold flux which may comprise salts and resinates of rhodium, iridium, bismuth, chromium, lead, cadmium, tin, copper, cobalt antimony, uranium, silver, palladium or platinum. Lacquers, e.g. nitrocellulose, rosin, synthetic resins and essential oils may be present.  The composition may be formulated as a paste, powder or suspension and may be applied by dusting, brushing, printing, stamping or spraying.  Suitable substrates to which composition may be applied include glass, ceramics, metals, quartz, carbon, mica, plastics, plastic/paper laminates, wood, paper, textiles (e.g. resin-impregnated glass fabric), leather, feathers, sea shells and mother-of-pearl.  Metallic gold films may be produced at relatively low temperatures, e.g. 160 DEG C., but higher temperatures including firing temperatures may be used where the substrate permits.  Conducting and non-conducting gold films may be formed.  The films may be protected by lacquering or varnishing or by laminating clear plastic over the film.

IPC: G01S13/92
Filed: 1951-05-17
Abstract: 808,830. Radar. MINISTER OF SUPPLY. May 16, 1952 [May 17, 1951], No. 11607/51. Class 40 (7). In a radio nagivation system in which the speed of an aircraft is determined by a known Doppler beat frequency system, the motor driving the speed indicator and associated both to the tracker is automatically disconnected from the radio receiver when the received signals are interrupted and is connected to a search device. The latter adjusts the motor speed to the value appropriate to the received Doppler frequency and the navigation system automatically resumes control. As shown, the tracker b receives Doppler beat signals from the aerial n through the filter f. The motor M operated from b drives the speed indicator i. An interruption in the signal to b from f causes the relay A to energize the motor 3 which rotates the contact brushes of the commutator 2. The contacts of 2 are each associated with tuned circuit so as to jointly cover the expected range of Doppler frequencies. When a Doppler signal is received, one of the tuned circuits is excited and the brush is caused to hunt above the contact connected to this circuit by the circuit 4 which simultaneously corrects the motor m through relay B to the potentiometer 5 ganged to the commutator 2. The motor m now operates at the correct speed for the existing Doppler frequency, the automatic system assumes control and relay B corrects motor m to b and the nagivation system.
