Filed: 1928-08-08
Abstract: 296,431. I. G. Farbenindustrie Akt.- Ges. Sept. 1, 1927, [Convention date]. Hydrogenation, destructive.-Hydrocarbons of low boiling-point are obtained by treating coal suspensions, tars, oils, &c. with hydrogen in several stages of diminishing pressure, the reaction product from a former stage being subjected to lower pressure in the following stage and the initial materials are exposed at least in the first stage to hydrogenation as a coherent liquid under high pressure, while the products in the final stage are heated in the vapour phase at low pressure. American crude mineral oil containing 40-50 per cent of constituents boiling above 350‹ C. is heated in the liquid phase with hydrogen at 200 atmospheres and at 450‹ C. in the presence of a catalyst containing molybdenum and chromium. The product is expanded into a second reaction chamber maintained at 20 atmospheres and 480‹ C. About 75 per cent of the products obtained are benzines boiling below 200‹ C. In treating heavy oils containing asphaltum pressures of over 1000 atmospheres are used and several stages are employed.

Title: Improvements in or relating to chemical nickel plating bath and process
IPC: C23C18/36
Filed: 1953-11-12
Abstract: An aqueous chemical nickel plating bath contains nickel ions, hypophosphite ions, and an amount of a stabilizing additive so as to inhibit random decomposition of the bath, and not substantially reduce the plating rate thereof, said additive comprising a long chain aliphatic compound containing at least 6, preferably 6-18, carbon atoms in the chain.  The additive is selected from the group consisting of aliphatic carboxylic acids and alkali metal salts and sulphates and sulphonates thereof, unsaturated aliphatic amines and salts thereof, unsaturated aliphatic long chain alcohols; specifically referred to are sodium and potassium oleate, 1 - hydroxyethyl - 2 - heptadacenyl - iminodazoline, the amineacetate known as "Armac T" (Registered Trade Mark), and the isopropanol amide of oleic acid.  The quantity of additive present in the bath, calculated as the aliphatic radical, should be not greater than 100 parts per 1,000,000 parts by weight of the bath, so as to form a hydrophobic film on the suspensoids that initiate the random decomposition, without forming such a film on the material to be plated (which is the usual catalytic material).

Abstract: 980,596. Fuel cells. ESSO RESEARCH & ENGINEERING CO. June 10, 1963 [Sept. 14, 1962; Oct. 19, 1962; Oct. 29, 1962; Nov. 27, 1962], No. 23033/63. Heading H1B. Fuel cell oxidants, particularly nitric acid, are regenerated by contacting their gaseous reduction products with a gaseous secondary oxidant in the presence of an aqueous acid solution, preferably the electrolyte used in the catholyte compartment. Such a regeneration reaction is carried out in the presence of a foaming agent, and a small amount of finely divided powdered solid may also be added to the regeneration mixture. Cell 1 comprises an anolyte compartment 6, an electrolyte compartment 4, and a catholyte compartment 5 divided by an electrolyte permeable barrier 5B into a cathodic reaction zone 5D and a catholyte recycle zone 5C. Oxidant enters compartment 5 via conduits 14 and 15, and from the nitric acid oxidant the gaseous reduction product NO is held trapped, e.g. by glass wool, in a regeneration zone 5A, through which electrolyte and secondary oxidant are bubbled to cause regeneration of nitric acid. The fuel is, e.g., hydrogen or methanol, the electrolyte is sulphuric acid, and the primary oxidant is HNO 3 , NO 2 , N 2 O 4 , HNO 2 , NaNO 2 , NaNO 3 , KNO 2  or KNO 3 . The secondary oxidant is O 2 , H 2 O 2  or air. In other embodiments, the regeneration process occurs outside the fuel cell compartment (Figs. 2, 3, 5 and 6, not shown) or zones 5D and 5C may be interchanged (Fig. 4, not shown). Openings 5B, 5B2, 5B3 in the permeable barrier 5B taper towards zone 5C to minimize the escape of air from zone 5C.

Abstract: 812,718. Winding wire, traverse mechanism. ETABLISSEMENTS G. DECOMBE. July 26, 1956 [Nov. 29, 1955], No. 23155/56. Class 120(2) An arrangement for winding filamentary material on a flanged spool, having a bar revolvably carrying a grooved member over which the material is engaged, is characterized in that the bar carrying the grooved member is bent along an arcuate line the tangent to which at a point corresponding to the middle of the bar is parallel with the axis of the spool so that the grooved member assumes under the action of the tension in the material a simultaneous longitudinal and rotary movement over the bar. In the arrangement shown a guide pulley 5 over which the wire 3 passes to the spool 2 is mounted on a sleeve 8 which is capable of rotation on and of being shifted slidingly over the curved guiding bar 9. The bar 9 is fixed to a member 10 by nut 12, a spacing member 14 being provided so that the transverse medial plane of the bar 9 can be adjusted to coincide with that of the spool 2. As the wire is wound on to the spool the side component of the tension in the wire shifts the pulley 5 along the bar 9 and prevents the wire from slipping axially along the bobbin.

The lug 14 also is constructed separately and has a serrated portion welded to the collar and a projection 15 extending between the turns of the spring to prevent tilting of the spring. The pinion is normally retained in the retracted position by a spring ring 22 in a recess in a sleeve la, and the movement of the pinion into engagement with the flywheel is limited by the engagement of the member 20 with the hooked end 21 of the spring.

[Class 135] [See also Group XXXIV] Valves adapted to cut off a vehicle brakeoperating cylinder from the pressure or vacuum source when a predetermined pressure or vacuum is reached or to be rendered inoperative, according to the load conditions of the vehicle comprises in one form, Fig. 1, for a vacuum system, a casing 1 connected to the cylinder and to the driver's valve at 6, 7 respectively and containing a diaphragm 2 connected to the cage of a ball-valve 8. When in applying the brakes, the vacuum in the cylinder and chamber 4 reaches a value sufficient to permit atmospheric pressure in chamber 3 to overcome the spring 10, the valve 8 is seated, but lifts to permit return flow of air in releasing the brakes. The device can be rendered inoperative by connecting passages 6, 7 by cock 9. In another construction, the chamber 3 is closed but can be connected either to atmosphere or to chamber 4 by a cock to render the device operative or inoperative. In a further form, Fig. 4, for compressed air brakes, the pressure in chamber 18 connected to the cylinder, moves the piston 12 against the action of a spring 14 to permit the valve 8 to seat and thus cut off the supply from chamber 19 to chamber 18. The spring may be adjusted to give varying cylinder pressures or the spring casing 13 be caused to abut on the piston to hold the valve off its seat to give the full pressure, by a cam surface 16 on a lever 15.

Aug. 14, 1934, No. 23416. Convention date, Sept. 23, 1933. [Class 36] [See also Group VIII] Electric conductors and apparatus are insulated with fibrous material, such as cotton, silk, asbestos, or paper which is impregnatedwith a dielectric liquid and coated with a fused resinoid, the resinoid being insoluble in the dielectric liquid and being applied to the fibrous material as a suspension of resinoid particles in the dielectric liquid, after which the particles are fused together to form a surface coating. The treated fibrous material may be formed into insulating boards, or may be formed into a roll, such as condenser bushing ; or a formed article, such as a transformer coil, having fibrous insulation may be treated with the suspension. The resinoid may consist of shellac, or of resins of the phenolic, glyptal, or vinyl types, whilst mineral insulating oil, or halogenated hydrocarbon compounds, such as a mixture of trichlorbenzene and chlorinated diphenyl, may be used as the dielectric liquid. The fibrous material, when in the form of a long strip, may be treated by passing the strip 1 through a suspension of resin in dielectric liquid 2, the strip then being wound into a roll 3 for storage, or being wound between heated rolls 4 into a body 5, e.g. a condenser bushing, the heated rolls 4 fusing the resin coating and causing successive convolutions of the wound strip to adhere. The Specification as open to inspection under Sect. 91 comprises also a process of making the insulating-material by coating one side of the fibrous material with a solution of resin and, after drying, then impregnating the material with a dielectric liquid. This subject-matter does not appear in the Specification as accepted.
