Title: Improvements in or relating to valves and operating mechanism therefor
IPC: F16K31/05
Filed: 1933-05-08
Abstract: 406,887. Valves; lubricating passages. MOREHEAD, F. H., Hempfield, Pennsylvania, MARTIN, J. C., Roosevelt Building, Los Angeles, and WALWORTH PATENTS, Inc., 28, Albany Street, Boston, all in U.S.A. May 8, 1933, No. 13374. [Class 135.] In rotary plug valves operated through toothed reduction gearing constituting a separable unit and having a valve-retaining ring 21, the unit and the ring are removable independently from the valve body, and special lubricating passages are provided. The gearing comprises a sun-wheel 66 operated by means of a hand-wheel 60, planet pinions 65 intermediate the sun-wheel and a fixed toothed ring 68, and lower planet pinions 63 on the same spindles as the pinions 65, and adapted to rotate a toothed ring 70 bolted to a spider 40. The spider has a square hole into which enters the squared end 14 of the plug 11. The gearing is contained in a housing H having a a flange 38, through which pass securing bolts 28. The latter also serve to secure the valve-retaining ring 21 to the body 5. A gland 25 is located between the ring 21 and an enlarged part 15 of the end 14, and can be adjusted without disturbing the valve or the casing H. Lubricating grooves 17, 20 of sinuous form communicate by passages 16, 19 with oil contained in a tube 80 from which it may be forced through a spring- pressed ball valve 86 by pressure exerted by means of a screw 88. Each groove extends half-way round the plug 11. In a modified construction, Fig. 5, the part 38<x> is extended to form legs 39<x> and a flange 40<x>. The retaining ring 21 is bolted as shown to the body 5.

Title: Improvements in or relating to the manufacture of amines of the benzene series
Filed: 1932-05-11
Abstract: Amines of the benzene series are obtained by heating a halogenated benzene with aqueous ammonia in an autoclave in the presence of an inorganic oxidant, e.g. an alkali metal chlorate, perborate, perchlorate or dichromate.  A metal or compound of a metal, including and subsequent to copper in the electromotive force series, may be present as a catalyst.  The preferred oxidant is a chlorate and particularly a mixture of a chlorate and a nitrate; copper, copper nitrate, cuprous oxide and silver chloride are mentioned as catalysts.  The starting material may contain a non-reactive group, e.g. a nitro, alkyl, acyl or carboxyl group. According to the examples, (1) aniline is obtained by heating chlorobenzene with aqueous ammonia in presence of potassium chlorate, ammonium nitrate and reduced copper; (2) p-phenylenediamine and p-nitroaniline are similarly obtained from p-dichlorobenzene and p-nitrochlorobenzene respectively.

Abstract: 936,583. Extruding. REYNOLDS METALS CO. April 19, 1960 [April 27, 1959], No. 13672/60. Class 83 (4). In the extrusion of metal tubes of varying diameters, a mandrel 100 is used comprising two portions 104, 112 of larger cross-section arranged alternately with two portions 108, 116 of smaller cross-section. A heated aluminium billet 12 is extruded by a ram 16 between a die 14 and the mandrel 100 to form a tube with internal and/or external thickened portions 126. The die bore and the cross-section of the mandrel may be circular, oval, square hexagonal, octagonal or triangular. The ram and mandrel may be integral or movable relatively to each other. A terminal end 120 of the mandrel determines the inside diameter of the forward end portion of the tube; the rear end of the tube is thickened externally only. The transition portions 114, 118 of the mandrel may be tapered or curved convexly or concavely, Fig. 9 (not shown). Other embodiments are described for forming tubes with two or more external thickenings. These tubes may be given a slight overall internal taper by using a mandrel with a slight overall taper.

Abstract: 501,128. Purifying liquids; gravityseparation apparatus. INFILCO, Inc. May 21, 1937, No. 14229. Convention date, June 5, 1936. [Classes 46 and 111] Liquids are treated, to remove undesirable substances therefrom, by admixing the liquid to be treated with liquid containing suspended solids from previously treated liquid, imparting motion to effect the admixture and to maintain in suspension substantially the whole of said solids contained in the liquid, and to cause circulation of such liquid containing suspended solids through a relatively quiescent separation zone and a relatively turbulent mixing zone, and withdrawing the treated liquid from the separation zone. A watersoftening apparatus is shown, the water being admitted by a pipe 12 into a central chamber 11 in which a turbulent mixing with slurry is effected, the slurry being sucked through radially arranged pipes 19 by an impeller 16 driven by a motor 17. The slurry is discharged into the raw water and the mixture is admitted to the bottom of the separation chamber through radial ducts 21. The slurry level is controlled by a draw-off cock 27, and the clear water is withdrawn by the overflow funnel 24 and pipe 25. A chemical precipitating medium may be admitted through a pipe 23, but water may be softened by mechanical means alone by passing the water over an aerator to remove dissolved carbon dioxide prior to passing it through the slurry bath. This may be followed by a further removal of carbon dioxide before admission to a second slurry bath apparatus.
