Title: Metal working lubricant
IPC: C10M163/00
Filed: 1959-04-14
Abstract: A lubricant composition for use in metalworking, especially as a drilling or cutting oil, comprises a major proportion of a hydrocarbon lubricating oil and a minor proportion of oil-soluble heat-treated sulphur containing less than 3% by weight which is insoluble in carbon disulphide, wherein the heat treatment of the sulphur has been effected by heating at a temperature below its melting point.  The lubricant composition may also comprise oiliness agents (i.e. saturated or unsaturated fatty acids having at least 12 carbon atoms or mixtures thereof) and/or activators (i.e oil-soluble sulphurized olefins, halogenated waxes and mixtures thereof).  Fatty acids which may be employed as oiliness agents include lauric, myristic, palmitic, oleic, stearic or linoleic acid, undistilled or distilled fatty acids derived from animal fats and oils (e.g. from tallow), fatty acids derived from vegetable oils (e.g. cottonseed, soyabean, coconut, palm or corn oil) and dimerized linoleic acid. The sulphurized olefins may be prepared by the treatment with sulphur or a sulphur halide of such olefinic materials as alkenes, propylene polymers, di- or tri-isobutylene, cyclohexene, pinene, stilbene or mixtures thereof.  In the examples, mineral lubricating oil compositions are described containing oil-soluble heat-treated sulphur with or without chlorinated paraffin wax and tallow fatty acids (and in one case also sulphurized C10-C18 wax olefins).  The oil - soluble heat-treated sulphur of the examples is prepared by heating amorphous sulphur at 200-220 DEG F. for 24 hours.

Abstract: 497,135. Photographic contact-printing apparatus. BURGESS, A. F. (Paper Patents Co.) April 29, 1938, No. 12857. [Class 98 (ii)] [Also in Group XI] A frame 13 supports parallel guides 17 for a thick glass plate 19 which receives the film transparency to be printed and which is secured to cross-heads 21 by clamps 27. The plate 19 is moved by a pair of screws 29 interconnected by worm gearing and a crossshaft 33 which is driven by a motor through mechanism providing two alternative speeds. The sensitized printing cylinder 47 is supported by yokes 51 carried by members 52 which slide vertically in guides formed on uprights 49. A connecting cross-head 53 is engaged by a threaded rod 53a engaging a cam on a shaft 54. Rotation of the shaft 54 enables the cylinder 47 to be brought into tangential contact with the plate 19, and rotation of the rods 53a adjusts the height of the cylinder support according to the diameter of cylinder employed. Printing is effected by a narrow beam of light directed through the plate 19 along the line of tangential contact with the cylinder 47 while the plate 19 is slowly traversed, the cylinder being rotated by frictional contact. The necessary high pressure is obtained by members 55, one on each side of the line of contact, supported by spaced arms 57 carried by transverse shafts 59, springs 65 being provided to produce an upward pressure at the opposite end of the pivoted arms 57. The width of the slot 69 through which the light passes is adjustable. The pressure exerted by members 55 may be relieved when desired by means of members 71 which may be forced upward against the pins 67 by a rotatable shaft 75 and toggle 76. The lamp structure comprises a reflector 83, arranged below arc carbons 87, and slidable on guides 93 by means of toggles 97 operated by a lever 99, to expose the carbons for inspection. To dissipate the heat of the arcs, the reflector 83 and hood 79 are hollow to receive a circulating cooling liquid, which also circulates through the hollow presser members 55. At the end of the printing operation, switches 115 stop the driving motor and extinguish the arcs.

Title: Process for the manufacture of oxide cathodes for discharge tubes
IPC: H01J9/04
Filed: 1929-04-25
Abstract: 311,705. Vereinigte Gl³hlampen und Electricitõts Akt.-Ges. May 14, 1928, [Convention date]. Vacuum tubes.-Deposition of an alkaline earth oxide on the unoxidized core of a cathode is effected by the simultaneous production in the evacuated container of the alkaline earth metal and the necessary oxygen, the cathode being afterwards heated to a temperature of from 1000‹ to 1500‹C. As material for the core, a refractory metal, such as tungsten, molybdenum or tantalum, is employed. In carrying out the invention, a compound or mixture which will produce, on heating, the required metal, or a mixture of metals, and also one which will evolve oxygen are applied, before assembly, to the side of the anode facing the cathode. After assembly and evacuation, heat is applied to the anode, the evolved metal vapour and oxygen combining to form oxide which is deposited on the cathode. For the production of the metal, a mixture of oxide and magnesium may be employed and, for the oxygen, manganese or barium peroxide or a mixture of these compounds. The materials for these purposes must be such as to evolve no deleterious vapours at the working temperature. The process is applicable to cores, such as platinum or platinum-iridium, which do not form oxides, or to an alloy of platinum and nickel. Preferably, a tungsten core is employed on which barium oxide is deposited.

Abstract: 570,808. Rubber threads. UNITED STATES RUBBER CO. Aug.'12, 1943, No. 13040. Convention date, Aug. 29, 1942. [Class 70] Ribbons of separable rubber threads are prepared by extruding an aqueous dispersion of rubber from a plurality of orifices into a liquid coagulant, containing in suspension flocculated tack-preventing particles, such as talc or bentonite clay, bringing the coated filaments into side-by-side contact, drying and vulcanizing. In an example a latex dispersion, preferably containing a stiffening agent such as 2.2-di- (p - - hydroxy phenyl) propane, is extruded through multi-jet nozzles N, Fig. 1, into a coagulating bath containing 50 parts of acetic acid, 50 parts of water, 10 parts of talc and 1.5 parts of oleic acid, the coagulant being circulated and agitated by means of a pump 29 and a system of rakes 42, stirrers, scrapers 38 and baffles. Each rubber filament T acquires a thin coating of flocculated talc before passing over a power-driven roller 14, the top of which is slightly above the level of the coagulant so that the filaments form ribbon R, the threads being held together by a talc bond. These ribbons, after passing over rods 15 and round drum 16, have excess liquid removed by doctor blades 19. After being stretched by rolls 20 and 21 and spaced by combs 25, the ribbons travel on conveyer belt 23 through the drier and vulcanizer. Other flocculating agents such as stearic acid, cetyl alcohol, aliphatic alcohols, mineral, animal or vegetable oils may be added to the coagulating bath in place of the oleic acid.

IPC: F02M19/10
Abstract: 131,677. Cox, A. July 31, 1918. Spray carburettors.-The flow of fuel from the nozzle of a spray carburettor for aeroplanes and the like in which tilting occurs is controlled by varying the pressures on the delivery and fuel inlet sides of the discharge orifice. This is effected by placing the nozzle d so that its delivery orifice is situated at the throat of a Venturi air passage a, and its inlet aperture at the throat c<1> of a Venturi portion of the fuel passage c in which the fuel is circulated by a force feed system. The passage a may be the main air passage or a branch passage as described in Specification 124,061. The arrangement ensures a constant supply of fuel under all degrees of inclination of the carburettor due e.g. to climbing, diving, &c. of the aeroplane or the like. To avoid the possibility of back pressure at the fuel Venturi due to tilting, two pumps may be employed, one to force the fuel into the conduit c and the other to withdraw it therefrom.
