Title: Improvements relating to the suspension of the live wire of electric railways
IPC: B60M1/23
Filed: 1927-08-06
Abstract: 293,213. Berg-, F. Aug. 6, 1927. Suspending cables. -The clamps and dropper wires which connect the live wire of an electric railway to its supporting cable are so constructed and arranged as to enable the height and tension of the live wire to be adjusted (before the clamps are secured firmly. A dropper wire c, Figs. 2 and 3, is secured to the live wire a, and to the supporting cable, by a clamp consisting of two jaws d<1>, d<2> which grip the live wire at their lower ends, and are spaced apart at their upper ends by a member d<3>. A bolt g, having crosspieces h at its ends, is passed through slots f in the jaws and is then turned through 90‹, the crosspieces h finally resting in depressions i to prevent them from turning backwards and allowing the jaws to open. The dropper wire c is passed around the member d<3> and is secured, as shown, by a clamp e<1>, e<2> the two parts of which are held together by a bolt g'. The external surfaces of the clamp rise slightly on each side of the slot so that when the bolt g<1> is turned, the crosspieces engage the inclined surfaces and draw the jaws together. When a live wire has been suspended, the clamps can be moved along the wire and the supporting cable, and the droppers can be shortened or lengthened as required by slackening the clamps e<1>, e<2>, witrout destroying any parts. After adjustment is effected, the crosspieces h, which are somewhat curved, are straightened by a tool of the kind described in Specification 293,258, [Class 61 (ii), Hand tools], and the clamps are securely closed. When the live wire is to be used with pull-off wires, the clamp d', a<2> is formed with an arm d<4>, Fig. 6, having recesses d<5> on its underside. The pull-off c<1> engages the arm, as shown, the particular recess d<5> being chosen so that the line of the pull-off c<1> passes approximately through the axis of the live wire.

Title: Process for the production of dihydro-m-thiazines-í¸-3,4
Filed: 1957-07-02
Abstract: Dihydro-m-thiazines- D -3,4 are prepared by reacting together a b -mercapto ketone, an oxocompound and ammonia or the ammonium salt of a weak acid such as ammonium carbonate or acetate, the simultaneous presence of ammonia or ammonium salt and mercapto ketone in the absence of oxo compound being avoided.  The reaction proceeds exothermically at room temperature, but in many cases cooling to 10 DEG  C. gives better yields.  The oxo-compound may be an aliphatic, alicyclic, aromatic, heterocyclic or aralkyl ketone or aldehyde, and may contain substituent groups.  The b -mercapto ketone may be purely aliphatic or may contain alicyclic, aromatic or heterocyclic radicals and/or substituent groups.  The products have medicinal uses and are effective as vulcanization accelerating agents, pest-control media, wood-preservatives, weed killers, rust-preventing agents and "anti-agers".  In examples: (1) 4,6,6 - trimethyl - dihydro - m - thiazine - D  - 3,4 is prepared from 2-methyl-2-mercaptopentanone-4, formaldehyde (or urotropine) solution and ammonia; (2) 2-ethyl-2,4,6,6-tetramethyl-dihydro-m-thiazine- D -3,4 is prepared by adding ammonia and 2-methyl-2-mercaptopentanone-4 to butanone containing some water; (3) and (4) 4,6,6 - trimethyl - 2 - o - oxy-phenyl - dihydro - m-thiazine- D -3,4 is prepared from salicylaldehyde, 2 - methyl - 2 - mercaptopentanone - 4 and ammonia and ammonium carbonate respectively.

IPC: H01F7/04
Filed: 1935-07-23
Abstract: 444,786. Magnetic chucks. BAERMANN, M., 30, Deutscher Ring, and DYNAMIT AKT.- GES. VORM. A. NOBEL & CO., Troisdorf Bez, both in Cologne, Germany. July 23, 1935, No. 20951. Convention date, July 23, 1934. [Class 60] [See also Group XXXV] A support or holder particularly for an electric lamp comprises a system of permanent bar magnets of high coercive force and soft iron pole shoes, a short-circuiting device movable out of action being provided in the space between the pole shoes and the magnets or the magnet itself being movable between the holding poles and a short-circuiting armature. In the form shown in Fig. 1, two magnets 1 abut against pole shoes 3 terminating in polepieces 11. Each polepiece is divided and bevelled as shown in Fig. 3 so that the holder can cooperate with a surface of any shape. A short-' circuiting armature 7 is slidable in non-magnetic guides 8 so that it rests on extensions 6 of the pole shoes 3 and thus short-circuits the magnets, or it can be withdrawn from the extension by means of a bolt 9 which when rotated by a thumb-piece 10 is raised by the action of a pin 43 on the curved surface of the cover plate 4. The lower part of the casing is closed by a non-magnetic plate 12. In a modification, Fig. 8, the pole shoes 17 are U-shaped, the short limbs abutting against the magnet 15. The short-circuiting armature 19 is adapted to bear against the bends 18 of the pole shoes. In a further modification, the magnet is attached to short polepieces and is movable by a cam or screw so that these polepieces bear either against the holding poles or against a short-circuiting armature. Alternatively, the magnet position may be changed by rotation. When a large holding surface or great strength is required as in chucks, a number of magnet systems may be mounted in a non-magnetic plate and separate short-circuiting armatures or a single spring armature may be controlled by cams to cause the magnet systems to be short-circuited and released in succession. As described, magnets and U-shaped polepieces similar to those shown in Fig. 8 are employed in this embodiment.

Patent GB-484469-A (GB)
Title: Improvements in the production of synthetic resins
IPC: C08F8/12
Filed: 1936-07-30
Abstract: The stability of resin prepared by condensation of polyvinyl alcohol or a hydrolyzed polyvinyl ester with a substance containing a reactive carbonyl group in the presence of sulphuric acid is improved by subjecting the resin to an hydrolysis or alcoholysis so mild as not appreciably to affect the acetal groups or ester groups if present.  Hydrolysis may be effected by very dilute acids (other than sulphuric acid), e.g. monobasic acids such as hydrochloric, hydrobromic or perchloric acids or by dilute solutions of acid-reacting salts, e.g. ammonium or zinc chlorides. Alcohols specified for the alcoholysis are methyl, ethyl, and iso-propyl alcohols.  Where the acetals are derived from aldehydes, there may be included bodies capable of reacting therewith, e.g. urea or other amides, or primary or secondary amines.  The resin need not be isolated before treatment: the sulphuric acid present may be neutralized, e.g. by sodium acetate, hydroxide, or phosphate, ammonia, or amines and the hydrolytic agent then added; or the reaction mixture may be poured into a solution of a soluble salt, e.g. sodium chloride, the sulphuric acid being neutralized and liberating the hydrolytic agent.  The resins before or after stabilization, may be neutralized by alkalies, alkali salts, or organic bases, e.g. by sodium acetate, carbonate, or hydroxide, ammonia, or amines.  The treatment may be carried out in the presence of a water-miscible swelling agent for the resin, e.g. acetic acid, dioxane or alcohols.  In examples: polyvinyl acetaldehyde, formaldehydebutyraldehyde, or formaldehyde-acetaldehyde acetal resins are treated with very dilute hydrochloric acid at room temperature; a polyvinyl acetaldehyde acetal resin is treated with the same at 100 DEG  C.; with an aqueous-isopropyl alcoholic solution of sodium acetate (with or without hydrochloric acid), with an aqueous solution of sodium chloride, or with a tert.-butyl alcoholic solution of hydrogen chloride; a polyvinyl butyraldehyde acetal resin is treated with a dilute aqueous solution of acetic and hydrochloric acids.
