Filed: 1916-07-22
Abstract: 108,178. Negus, E. J., Charles, F., and British United Shoe Machinery Co. July 22, 1916. Heels, machines for.-Heel-attaching machines, particularly of the type described in Specification 23031/11, are provided with means to effect, during the relative approach or separation of the work-engaging members in the direction of the height of the work, a corresponding relative approach or separation in a transverse direction. The invention is described as applied to a machine of the type described in the above-mentioned Specification, the upper work-engaging member C being mounted to slide on horizontal guides 1 attached to the lower end of the usual plunger C'. The lever G to which the treadle rod is connected has attached to its bearing an arm 2 forked to receive a freely rotatable pivot pin which holds adjustably the end of a rod 4. The rod passes over an eccentric stud 8 carried by a bracket 9 and is bevelled at its end 13 to engage an arm 12 depending from a shaft 11 journaled in a bearing also carried by the bracket 9. The shaft 11 also carries an arm 14 having at its lower end a long sleeve bearing 15 in which is mounted to slide freely a rod 16 having a hook portion 17 engaging a pin 18 on the front of the member C. When the treadle is depressed, the plunger C' commences to move downwards and the member C is advanced from its retracted position against the action of a spring 19 until a shoulder 22 engages a stop pin 21, when the plunger and member are in alinement. Further movement of the treadle causes the plunger to force the member downwards to engage the work, and then starts the power mechanism to compress the heel and drive the fasteners. If it is desired to render the device inoperative, the hook 17 may be removed from' the pin 18 and the rod 16 held up in its sleeve by means of a cotter pin 24.

Title: Improved process for protecting ferrous metal articles from atmospheric corrosion
Inventor: ZENFTMAN HENRYK
IPC: C23C22/07
Filed: 1954-04-09
Abstract: The surface of a ferrous metal article is protected from atmospheric corrosion by treating it with an oil-in-water emulsion in which the oil phase contains in solution a derivative of ortho-phosphoric acid containing a first hydroxyl group, the hydrogen atom of a second hydroxyl group being replaced by an alkylated aryl radical whose alkyl group contains at least 8 carbon atoms, and the third hydroxyl group being either a free group or having its hydrogen atom replaced by an alkyl group containing not more than 4 carbon atoms, and drying the thus treated surface.  The oil may be a mineral oil or an ester oil of animal or vegetable origin, e.g. castor oil or linseed oil; many examples are given of orthophosphoric acid derivatives that may be used.  The emulsion may be made by dissolving the orthophosphoric acid derivative in the oil, preferably at raised temperatures, and then agitating the resulting solution with its own volume of water, the emulsion thus produced being further diluted with water as required.  The article may be totally immersed in the emulsion or the emulsion may be painted or sprayed on the article, and then drying is preferably effected by draining the surface and then heating it. Specifications 699,080, 709,628 and 743,752 are referred to.ALSO:The surface of a ferrous metal article is protected from atmospheric corrosion by treating it with an oil-in-water emulsion in which the oil phase contains in solution a derivative of orthophosphoric acid containing a first hydroxyl group, the hydrogen atom of a second hydroxyl group being replaced by an alkylated aryl radical whose alkyl group contains at least eight carbon atoms, and the third hydroxyl group being either a free group or having its hydrogen atom replaced by an alkyl group containing not more than four carbon atoms, and drying the thus treated surface.

Abstract: 759,080. Making composite electrodes. TELEFUNKEN GES., [formerly TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE GES.]. April 12, 1954 [April 10, 1953; March 5, 1954], No. 10647/54. Class 83 (2). In a method of making electrodes for electron discharge devices a sheet of metal which enters into intermetallic association with aluminium is coated with a layer of aluminium and after annealing and simultaneously forming the intermetallic compound is coated with a second layer of aluminium for subsequent conversion after the material has been shaped into electrode parts. Sheet nickel or iron of low oxygen content of about 3 mm. thickness with aluminium foil 0.1 mm. thick applied on one or both sides is rolled down to a total thickness of 0.15 mms. with the aluminium between 3 and 10 microns. The sheet is then annealed at 675‹ C. and the black intermetallic compound formed. A second layer of aluminium of about 15 microns is then applied by low pressure rolling and the sheet is stamped into electrode parts which are subsequently mounted in a discharge device and heated to a temperature of about 800‹ C. to form the intermetallic compound from the second layer of aluminium and degass the assembly. In a modification the composite material may be further annealed prior to the stamping operation. The composite material may also be degassed prior to insertion in the discharge device by heating, to 500‹ C. in air, hydrogen, nitrogen, coal gas or ammonia at atmospheric or a reduced pressure.
