A stapling machine comprises a staple carrying arm 17 pivoted to a base 15, a pusher 23, a punch 19 co-operating with an anvil 18 and a magazine 21 adapted to contain a number of tiers of staples 39, the pusher being retractable to allow each tier of staples in turn to move into position for use on the arm when the staples of the previous tier have been used up, means 42 being provided to urge the tiers of staples towards the said position. The arm 17 is of U- shape section and is pivoted at 16 on lugs formed on the base 15, the arm being raised to the position shown in Fig. 1 by a spring 43. The pusher is arranged to slide within the arm and is urged against a block of staples by a spring 31. A pin 32 on the pusher passes through a slot 33 in the arm and is connected by a flexible wire 34 to a handle 37 so that, when a block of staples is exhausted, the handle is pulled thereby retracting the pusher to allow a further block of staples to drop into the arm under the action of a weight or spring 42; an extension 38 on the pusher prevents the remaining block of staples in the magazine from dropping into the arm. In the modification shown in Fig. 7, the arm 45 and base 44 are pivoted at 46 to act in the manner of a pair of pincers, the punch 52 being operated via a linkage 56, 57. In a further modification, Fig. 8 (not shown), the magazine is in the form of an oblong box having a removable lid instead of the door 22 shown in Fig. 1.

Abstract: 765,174. Mandrels. WESTERN ELECTRIC CO., Inc. Feb. 23, 1955 [Feb. 26, 1954], No. 5424/55. Class 83 (4). A mandrel for internally supporting a rectangular-sectioned tube while it is bent by apparatus designed to give a sharp angular bend to its inner wall comprises a stem, adapted to be slidably inserted in one end portion of the tube and carrying at its end a rotatably mounted pivot block, and a body member adapted to be slidably inserted in the other end of the tube and detachably secured to the pivot block inside the tube. In one embodiment, Figs. 2, 7, the mandrel includes a stem 15 rotatably carrying at one end and in interleaved engagement with flanges 17, 28 thereon, a pivot block 36. The stem 15 and pivot block 36 are inserted in one end of a wave-guide 12 to be bent so that a shoulder 13 at the other end of the stem 15 engages the end of the tube 12. A body part 44 of the mandrel is then inserted in the other end of the tube 12 so that a shoulder 46 thereon engages that end of the tube and the body member 44 is secured, by a screw 52 passing therethrough, to the pivoted block 36. The tube 12, held by members 60, 63, is then bent by rotating tube engaging members 62, 64 as described in Specification 765,173, to which reference is made, so as to give the tube a sharp, angular inside bend 68 and a smooth outer bend 61. The tube is supported interiorly, at the inside of the bend, by a plate 57 on the body 44 and a plane face of the stem 15 and, at the outside of the bend, by surfaces 40, on flanges of the pivot block 36, and surfaces 19, on the flanges 17, 28 of the stem 15. The surfaces 40 and 19 are of a curvature equal to the widths of the tube 12 in the plane of the bending and are so arranged relative to one another that when the tube has been bent to the required angle the surfaces are in alignment. The body 44 of the mandrel is disconnected from the pivot block 36 after bending and the parts of the mandrel are withdrawn from the bent tube. In another embodiment, Figs. 9, 12, for supporting a wave-guide 12, already given one bend, while a further bend is given thereto, a stem 15 has rotatably secured thereto a laminated pivot block 69. A composite body member, inserted into the previously bent part of the tube, comprises a connecting block 104, for attaching the body to the pivot block 69, an end member 134 and curvilinear top and bottom links 120, 122 connecting the block 104 to the member 134. The block 104 is locked to the pivot block 69 by a screw 143 after insertion into the tube.
Patent GB-577364-A (GB)
Title: Process for the dehydration of 3-methyl-butenol
IPC: C07C1/24
Filed: 1944-03-24
Abstract: Isoprene is produced by heating 3-methyl-1-butene-3-ol with a salt of a weak nitrogeneous aromatic base with a strong acid, for example aniline hydrobromide, aniline benzene-sulphonate, o-toluidine o-toluene sulphonate, and a -naphthylamine p-toluene sulphonate. These salts selectively dehydrate the 3-methyl-butenol in the presence of the corresponding saturated alcohol.  The quantity required is 2-10 per cent by weight of the alcohol.  Solvents or diluents of higher boiling point than the alcohols may be used, for example aromatic hydrocarbons such as toluene, xylene and ethylbenzene, solvent naphtha, ethers such as dibutyl ether, esters such as butyl acetate, acetals, and ketones such as methyl-isobutyl-ketone.  The salts are soluble in the unsaturated alcohol and may be precipitated when this has been converted. Instead of the pure salts, mixtures of the base and acid with either in slight excess may be used.  Fresh alcohol or mixtures containing it may be added to the boiling reaction mixture at the same rate as that present is dehydrated and isoprene distils off.  In examples: (1) a mixture of the methyl-butenol and methyl-butanol is heated with aniline hydrobromide in a still with reflux, pure isoprene distilling over; (2) the methyl-butenol is heated with aniline hydrobromide and ethyl-benzene; (3) and (4) aniline benzene sulphonate is used with xylene or dibutyl ether; (5) and (6) mixtures of the unsaturated and saturated alcohols are treated with the same salt with or without butyl acetate.

Title: Improvements in or relating to silver halide photographic film elements
IPC: G03C1/85
Filed: 1953-03-04
Abstract: 725,336. Anti-static photographic film. DU PONT DE NEMOURS & CO., E. I. March 4, 1953 [April 9, 1952], No. 6073/63. Drawings to Specification. Class 98 (2). A film support carries on one side a colloidsilver halide emulsion layer and on the other side a layer of a film-forming binding agent containing a Wemer-type chromium complex in which trivalent chromium is co-ordinated with an aliphatic carboxylic acid group containing less than six carbon atoms, an aromatic carboxylic acid group containing seven carbon atoms, an aralkyl carboxylic acid group containing not more than eight carbon atoms, or any such acid group containing at least one dipole group such as Cl, Br, I, nitro, hydroxy or phenoxy. In eight specific examples the film support is always polyethylene terephthalate; the binding agent is a polyvinyl alcohol base acid complex, polyvinyl alcohol or gelatin; and the chromium complex that of p-nitrophenylacetic acid, p-nitrobenzoic acid, phenyl acetic trichloroacetic acid or thioglycollic acid; but numerous other film supports generally of hydrophobic type, other binding agents of both water-permeable and resinous or hydrophobic types, and other chromium complexes are quoted. The complex may be mixed with a solution of the binding agent in water or organic solvent as appropriate and applied to the film support as from extrusion orifices or transfer rollers, or by skim coating, followed by drying, and then a sublayer, a colloid silver halide emulsion layer or a plurality of such and filter or protective layers if required are applied to the obverse side of the support. An apparatus for measuring static charges acquired by a film travelling over a roller is described, results showing that untreated polyethylene terephthalate film builds up a charge of - 20 kilovolts when passing over a brass roller and treated film only - 0.35 to - 3 kilovolts, with reduced tendency to show static markings. The chromium complexes may be made by reacting chromyl chloride with a carboxylic acid as described above in organic solvent, or by making a solution of chromium trioxide and hydrochloric acid in water with a monohydric aliphatic alcohol and then with a carboxylic acid, and preparation of the complex of p-nitrophenylacetic acid, used in Examples I and II, by this latter method is described in detail. Specifications 550,246, [Group IV], and 654,342, [Group IV (a)], are referred to.
