Abstract: 1,184,520. Control of motors. R.C.A. CORPORATION. 18 July, 1968 [19 July, 1967], No. 34383/68. Heading H2J. [Also in Division F4] The driving motor 38, associated with an automatic lamp changer comprising a carriage carrying a pair of lamps 12, 14, one of which is operative and the other spare, has a control circuit wherein the output obtained from an AND circuit 120 when the operating lamp 14 fails with the spare lamp 12 operable is passed to a further AND circuit 132 which is controlled by a pulse generator 134 to give an output to operate the motor switches 66, 68 when the A.C. supply passes through zero so that electrical interference when the motor is energized is a minimum. If the spare lamp 12 is inoperable when the operating lamp 14 fails the input to the first AND circuit 120 from a filament testing circuit is not present so there is no output from the first AND circuit 120 and the motor does not start. A warning lamp 144 is lit to indicate a fault. Filament testing circuits are associated with each lamp, each comprising a photocell 104 in a light tight enclosure 106 with a gas filled tube 100 which remains alight while the lamp is operative, but extinguishes if the filament fails thus causing a signal to be fed to an AND circuit 136 or 138 to operate warning lamp 144 if a signal is also present indicating that the lamp is spare. Two switching elements 66, 68 are necessary in the motor switching circuit because the motor acts as an inductive load and if the pulses from pulse generator 134 were applied to one switching element alone the pulse would have ended before the current in the motor were zero so that only a small fraction of each power cycle would be applied to the motor. The carriage cannot remain at a position between its extreme positions when the lamps are correctly placed because if vane 16 does not cut off the light from either cell 50 or 52 the motor will be energized and the carriage will move.

Title: Improvements in the production and treatment of artificial threads, fibres and the like
IPC: D01F4/00
Filed: 1938-11-26
Abstract: 521,856. Artificial filaments etc.; treating textiles with liquids &c. DREYFUS, H. Nov. 26, 1938, No. 34485. [Classes 2 (ii) and 15 (ii)] Artificial filaments, fibres, threads or fabrics, of protein or protein-like material which contains less than 1.5 per cent. of sulphur are caused to react with sulphur or its equivalents in elementary. form, so as to increase their resilience. The filaments may be made of casein, zein, ground-nut protein, gelatine, or long chain polypeptides obtainable by condensing acid chlorides of chlor fatty acids with amino groups, replacing the chlorine in the product by an amino group by the action of ammonia and repeating the process, or similar compounds obtainable by condensing polyamines with dicarboxylic acids. Mixtures of proteins with viscose, cuprammonium cellulose, or alkali-soluble cellulose ethers may be used in forming the spinning solutions. Casein may be dissolved in an aqueous solution of sodium or potassium polysulphide and spun into dilute sulphuric acid containing ammonium sulphate. The threads are washed and, if desired, treated with formaldehyde. They are dried and then subjected to dry heat, e.g., between 100 and 120C. to effect reaction between the protein and sulphur. The spinning solution may contain thiocarbanilide, phenyl thiocarbamide, hexamethylene tetramine, aldehyde ammonia, oxides or iodides of amphoteric metals or other substances acting as sulphur carriers. A watersoluble thiosulphate in solution in aqueous caustic soda, potash, ammonia, urea, or other casein solvent, may be used as the source of sulphur. Casein may be dissolved in caustic soda and the solution may then be saturated with hydrogen sulphide. Instead of treating the threads during their production, they may be treated subsequently with compounds capable of liberating sulphur. They may be impregnated with sulphur dissolved in carbon bisulphide. Instead of sulphur, selenium or tellurium may be used. The provisional Specification describes also the use of compounds which introduce other elements in addition to sulphur into the protein molecule, e.g., thiophosgene, halogenated mercaptans and alkyl sulphides.

Title: Improvements in or relating to solid carbonaceous fuels
IPC: C10L9/10
Filed: 1932-12-08
Abstract: Sulphonic acid compounds derived from heavy petroleum or hydrocarbon oils, naphthalene, benzene, the higher alcohols, organic sulphur compounds, &c. are applied, as by spraying aqueous or organic solutions, to solid fuels such as coal, coke, or briquettes to form a film thereover which retards surface disintegration or slacking and formation of dust during transport &c.  A freezing point depressant such as sodium chloride or molasses &c. may be added to aqueous solutions, or substances tending to lower the pour point may be added to oil solutions.  A slightly acid 15 per cent solution of sodium sulphonate derived from petroleum may be used, about \ba1/3\be-2 lbs. of solid compound being necessary for each ton of coal.  For winter conditions, however, aqueous solutions of alkali metal sulphonates obtained from petroleum oil acid sludge may not be stable and ammonium sulphonates may be employed, examples of the preparation of which are described.  Amines and substituted amines may be used in place of ammonia to neutralize the sulphonated compounds.  The acid is preferably applied in a number of treatments, the first sludge being discarded.  The sludge from remaining treatments is washed with water, sulphuric acid separated and withdrawn and the remaining sludge neutralized with ammonia; or if the sludge emulsifies it is allowed to separate into layers which are washed separately.  The washing water may contain an electrolyte to aid separation, such as sodium chloride, ammonium sulphate or hydrochloric acid.  Oil soluble sulphonic compounds retained in the oil after the treatment of oils with sulphuric acid may be removed by washing with a solvent such as isopropyl alcohol which may then be used with or without neutralizing the sulphonic acids as a fuel treating agent.  Or the sulphonic acids or salts may be separated and made up as a solution in alcohol, water or a mixture thereof.  Low boiling oils such as gasoline, naphtha, &c. may also be used when fire risk does not arise, otherwise the compounds may be dissolved in gas oil &c.ALSO:Heavy petroleum or hydrocarbon oils, naphthalene or benzene are sulphonated and applied to solid fuels to form a film which retards surface disintegration or slacking.  Preferably the hydrocarbon oils are subjected to a number of treatments, the first sludge being discarded.

Filed: 1922-12-27
Abstract: 213,647. Thornton, J. E. Dec. 27, 1922. Drawings to Specification. Kinematograph picture films; colour photography; bichromated colloid processes.-Relates to positive films in natural colours, of the kind built up from thin component monochrome films as described in SpeciBoaticns 26786/11 and 25064/13, and consists in a flm built up by cementing together in register, with their image faces in contact, two films of half standard thickness, each carrying a series of monochrome pictures printed photographically in a readycoloured, non-waterproof colloid layer on a celluloid or like waterproof base, one series being orange-red and reversed with respect to the other, which is blue-green. The image-bearing colloid layers are protected from scratching by being enclosed between the celluloid or like base layers. For protection in handling the thin component films during printing, developing, &c., the films may be temporarily mounted during manufacture on a reinforcing layer of paper, which is not stripped off until the cementing operation is reached. The images may be produced in relief or non-relief by any known processes, numerous examples of which are stated, the preferred processes being the rapid silver bromide process, including the carbograph process, and the slow bichromated gelatine process employing pigments or dyes. The images may be printed separately or simultaneously from separate negative strips, or from a doubde-width negative strip carrying the component image series side by side, upon separate positive strips, or upon a double-width positive strip coloured orange-red and blue-green respectively on one side and on the other of the central longitudinal line. When separative positive strips are printed, the films carry marginal identification marks to facilitate correct assembly for cementing. Printing is performed (a) from the front for non-relief images, in which case the reinforcing strip of paper, if used, is carried on the celluloid or like back; or (b) through the back for relief images, in which case the reinforcing paper, if used, is carried on the colloid face, and is porous to permit access of developer &c. to the colloid layer. Registration is secured, during printing, in known manner, by means of accurately formed feed perforations. The component films are finally assembled face to face and cement together under pressure in accurate register. The reinforcing layers of paper, if used, are stripped off before cementing in the case of relief images, and either before or after cementing in the case of non-relief images. Specification 188,329 also is referred to.

Abstract: 1,098,181. Stamping. PLESSEY-UK Ltd. Sept. 4, 1964 [Sept. 6, 1963], No. 35340/63. Heading B3Q. [Also in Divisions B4 and F2] An extending strut for pressing and crimping tools comprises two arms 1, 10 linked together by a cam-track 9 on arm 1, and a pin 12 on arm 10 which is movable around the track 9 upon relative movement of the arms. The track 9 is in the outer surface of a sleeve 7 which is held on the arm 1 by a circlip and may rotate on the arm in one direction only, rotation in the opposite direction being prevented by ratchet springs 3 in the arm 1 bearing against the wall of a recess in the sleeve. The ends of a straight section of the cam-track are joined by an inclined section, the strut being free to open and close with the pin 12 engaging the straight section. If the pin passes beyond the straight section of the cam during closure of the strut, causing rotation of the sleeve 7, complete closure of the strut must follow, after which the pin travels along the inclined section to the top of the straight section, since any reversal of movement of the arms is prevented by the springs 3. Thus, incomplete diemovements are prevented. The strut may be located between the handles of a lever tool.
