Title: Improvements in or relating to valves
IPC: F16K5/22
Filed: 1926-11-24
Abstract: 265,144. Merco Nordstr÷m Valve Co., (Assignees of Nordstr÷m, S. J.). Feb. 1, 1926, [Convention date], Plug cocks. - A plug cock in which lubricant under pressure is used to lift the plug from its seat for lubrication comprises a flexible ring or flange 14 formed integrally with a screwed sleeve 15 screwed on the spindle 16 and having superposed compressed packing 17. In opening the cock the screwed spindle moves the screwed sleeve 15 downwards thus relieving the compression of the packing 17 until the lower end of the sleeve, at 30, abuts upon the plug 10 thus locating the open position of the cock and bringing to a minimum the pressure between working surfaces of the plug and casing. In closing the cock the sleeve 15 is moved upwards thus increasing the ccmpression of the packing, and consequently the pressure between the working faces of the plug and casing, to a maximum which also locates the closed position of the cock. Lubricant is forced in the usual manner from a chamber 47 by a screw 48 through grooves 42 into a lower chamber 39, and also through a radial hole 50 to the screw threads.

Title: Improvements in or relating to sealing arrangements for use between two relatively rotatable members
IPC: F16J15/54

Abstract: 830,062. Stuffing-box substitutes. SVENSKA KULLAGERFABRIKEN A.B. Sept. 17, 1958 [Sept. 30, 1957], No. 29742/58. Class 122 (5). [Also in Group XXXIV] In a sealing arrangement between two relatively rotatable members, such as a shaft 12, Fig. 2, and a roller bearing housing 16 comprising an elastic O-ring 14 mounted under tension on a conical surface 13 on one of the members concentric with the axis of rotation and arranged so that the ring is urged against a surface 15 on the other member transverse to the axis of rotation, the angle between the axis of rotation and the generatrix of the conical surface is less than 30 degrees. The conical surface may be on the shaft or on a ring secured thereto or on the bearing housing. To facilitate assembly the small end of the conical surface 21, Fig. 5, may be provided with an opposed conical surface 22. In a modification applied to a ball-bearing, Fig. 6, the O-ring 27 is mounted on a conical flange 26 of a sheet metal ring 24 fixed in the outer race 23 and bears against a sheet metal ring 28 seated on the inner race 30. In other modifications, the conical surface is formed directly on the inner race or on a member secured to the outer race. The embodiment shown in Fig. 10 indicates a self-contained unit comprising a sleeve 39 having two oppositely directed conical surfaces on each of which is mounted under tension an O-ring that engages a surface 40 of a sheet metal ring sealed to the shaft 41 by a packing ring 38. In the arrangement shown in Fig. 12 in which a shaft 48 passing through a wall 47 is sealed by the O-ring 44, the rings 45 and 46 act respectively as reserve rings for rings 44 and 45 in the event of the latter being damaged or breaking.

Patent GB-300133-A (GB)
Abstract: 300,133. Stedefeld, C. Nov. 5, 1927, [Convention date]. Addition to 291,723. Welding railway rails. - In a portable apparatus for electrically welding continuous rail lengths on railway tracks, which carries a welding transformer together with devices for gripping, guiding, moving and supplying current to the rail ends and is symmetrically arranged with respect to the rails as described in the parent Specincation, the butting pressures are resisted only by pure tension and compression stresses in the framework of the carriage, so that rigid guiding is obtained with an apparatus of minimum weight. The clamps 24, 25 together with the brackets 23, 29 through which the pressure is transmitted are separately secured to the rails before application of the welding apparatus. The operating piston applies the pressure by a lever 22 pivoted on the tension member 17 of the frame, the reaction of the cylinder 21 being transmitted through rods 27 to a lever 28 pivoted at the other end of the frame 17. The brackets 23, 29 are secured to the rail in fish plate fashion by screwing or by single or double-armed pivoted clamps 24, 25 operated by a screw 26. In repair welding with a rail of different height the running surfaces are placed at a common level by means of underlays and the guide rollers 30, which are supported uncovered beneath the frame, are vertically adjustable to correspond with the displacement of the grooves. For this purpose the eccentrically mounted rollers 30 are adjusted by a screwed bush 33 rotated by worm gear from a hand wheel 35. The worm shafts of opposite guide rollers may be coupled together to ensure a uniform adjustment. In welding rails on suspended railways, the distance between the rollers is arranged so that the lateral rail carriers are intermediate thereof to permit welding without removal of the carriers.

Class 146(3) The end portion 18 of the reservoir tube 10 of a ballpoint pen has at least one exterior air-vent groove 22 extending from the rear end at 26, and a closure cap 16 is fitted over the portion 18 to cover the groove 22 but leaving the forward end of the groove open to atmosphere and the rear end at 26 in communication with the interior of the reservoir. There may be three or more grooves 22, formed during the moulding of the reservoir tube, and these may be of rectangular cross-section with a depth of about 0.0025 inch and a width of at least 0.002 inch. Such fine grooves prevent leakage of a quick drying ink under all conditions, since the minute amounts of ink which can enter the grooves are exposed to the atmosphere and are dried rapidly to seal up the grooves. The tube 10 may be of transparent material, and the cap 16 of metal. Specification 791,109 is referred to.

Abstract: In the manufacture of solutions, films, artificial filaments, celluloid-like masses, electric insulating-materials, varnishes, cooling and other compositions, preparations, and articles having as a basis the aliphatic cellulose ethers of Specification 164,374, the alkylated sulphonamide derivatives or preparations of Specifications 132,283, 133,353, and 154,334 are employed as high boiling point solvents or plastic-inducing agents; the cellulose ethers may be used alone or mixed with other ethers, esters or derivatives of cellulose, and in conjunction with the sulphonamides there may be used other high boiling point solvents such as triacetin, and lower boiling point solvents or liquids, and other additions such as triphenyl or tricresyl phosphate, castor oil, aliphatic derivatives of urea, colouring-matters, filling-materials, &c.  In an example, a celluloid is prepared from an ether obtained according to the examples given in Specification 164,374, using as a high boiling point solvent, benzene mono-methyl sulphonamide, toluene-o-mono-ethyl sulphonamide, or mixtures of isomeric xylene mono-methyl or mono-ethyl sulphonamides in conjunction with triphenyl phosphate or tricresyl phosphate, and benzol; the hardness of the product is adjusted by increasing and decreasing simultaneously the proportions of sulphonamide derivative and triphenyl or tricresyl phosphate.  In another example describing a solution for use in the manufacture of films or as a varnish, the ether is dissolved in alcohol or alcohol-benzol, and the sulphonamide derivative added, with or without triphenyl or tricresyl phosphate.
