Title: A method of and device for the manufacture of precision profiled bars by means of radial pressing
IPC: B21C1/16
Filed: 1965-01-14
Abstract: 1,079,811. Making profiled bars; swaging; planing; rolling. SMERALOVY ZAVODY NARODNI PODNIK. Jan. 14, 1965 [Jan. 16, 1964], No. 1613/65. Headings B3A, B3H, B3L and B3M. A precision profiled bar from which small toothed pinions may be cut is made by radially pressing wire or bar stock to the approximate outline of the required profile, radially pressing to a more precise form of the profile, calibrating by rolling by form discs, shaping the outer periphery of the profile by passing it through a cutting die, and separating a required length of the profiled bar from the wire stock. The pressing operations are performed by a set of rough-pressing jaws 8 and a set of finish pressing jaws 9, each set being accommodated in a conical recess in a cylinder 4. The jaws abut against centring bushes 5, and horizontal movement of the cylinders 4 causes radial movement of the pressing jaws. The cylinders 4 are moved horizontally by the vertical movement of a wedge-shaped drive member 2 which is depressed by a press slide (not shown). Springs 18, 19, 20, 22 return the various parts to their initial positions when the press slide is retracted. Movement of the press slide also causes horizontal movement of a carrier 21 by means of a linkage (not shown) Mounted on the carrier 21 are the calibrating discs 10 and the cutting die 16 which cuts a layer from the periphery of the profile. Movement of the carrier 21 in the direction opposite to the arrow S causes the bar to be rolled and trimmed by the die 16, movement of the wire stock with respect to the pressing assembly 1 being prevented by a retaining collet (not shown), and movement of the carrier in the direction of the arrow S causes the wire stock to be fed into the machine. The machine is lubricated with thin oil.

Title: An improved process and apparatus for welding plates
IPC: B23K33/00
Filed: 1928-01-20
Abstract: 286,213. Schaer, C. Feb. 28, 1927, [Convention date]. Welding.-In welding plates the meeting edges ara bevelled, a separate rod-like bridge member preferably of the same length as the joint is placed over the joint on the upper surface of the plates and the parts then heated and pressed together, during which process the edges of the plates are bent or turned over and welded together with the rod. The rod 3 may be of triangular, square, polygonal round or other shape and may rest directly on the plates 1, 2, or on a distance piece. In making circumferential welds the rod is previously bent to shape. The parts are heated by burners 15, 16 which may be regulated to reduce the heat during the pressing operation or may be moved to preheat anadjacent part of the joint. The welding is effected by jaws 4, 5, which may be shaped so as to :force the rod between the plates step by step to effect a gradual change from its initial to its final shape. The upper jaw is grooved to prevent lateral deflection of the rod. The rod may have a rib 17 to guide it between the plates. The jaw 4 may be mounted in a cylinder 7 carried by a frame 6 and operated by water, compressed air, or steam. The jaw 5 is mounted on a rod passing through a sleeve 8 carried by a horizontal support 9 and co-operating with a block 10. The feed may be effected by traversing the work or the jaws. The Specification, as open to inspection under Sect. 91 (3) (a), describes a modification as shown in Fig. 10, (Cancelled), in which the bridge member 3 is formed integral with one of the plates. This subject-matter does not appear in the Specification as accepted.
Patent GB-822073-A (GB)
Title: Process for the deposition of metal layers in or on tubes
IPC: C23C16/04
Filed: 1957-01-18
Abstract: In a process for the deposition of metal coatings on tubes by the pyrolysis of volatile metal compounds, the vapours of the said compounds, preferably in admixture with a carrier gas e.g. CO and/or reducing gas e.g. hydrogen, are conducted through or over the tubes which are indirectly heated progressively over their entire length in sections to the decomposition temperature of the compounds.  The heating may be performed by effecting relative movement between the tubes and a furnace which is shorter than the tubes.  Ceramic tubes for use as chambers for catalytic reactions may be interiorly coated with the catalyst e.g. platinum by the decomposition of platinum carbonyl chloride.  In tubes for the synthesis of hydrocyanic acid from ammonia and hydrocarbons a platinum catalyst containing a small amount of aluminium is desirable: in this case an aluminium alkyl e.g. the tributyl or tripropyl, may be coemployed.  If the exterior of a tube is to be coated it is made gas-tight and introduced into another tube, the metal compound vapour being conducted into the peripheral chamber thus formed.

Title: Improvements in or relating to feeding mechanism for sewing machines
IPC: D05B27/10
Filed: 1939-01-21
Abstract: 510,072. Sewing-machines. MERROW MACHINE CO. Jan. 21, 1939, No. 2170. Convention date, Jan. 22, 1938. [Class 112] In order to guide the work automatically to produce a straight seam, a sewing-machine is provided with a device adapted to engage the work in advance of the feed mechanism and to be moved against a resistance so that the work is kept under tension. The invention is shown applied to an overedge sewing-machine for connecting the edges of two superposed pieces of fabric which are afterwards opened out to lie flat edge-to-edge ; the machine has a curved needle 2, trimming knife 6, feed dog 4, presser-foot 3, needle-plate 5 and work-table 11. The righthand end of the table is shown broken off and placed beneath the remainder. A member 21, running on rails 25 and projecting through a slot in the table surface 11 in line with the stitching point, has pivoted to it a plate 28 carrying pins 29 on which the rear end of the work is impaled so that as the work is fed past the needle in the usual manner it pulls the member 21 along against the resistance provided by a weight 30 on the end of a chain 31 attached to the member 21 ; the work is thus kept taut and straight in its passage up to the needle. The pins 29 are automatically retracted from the work when the member 21 is near the needle by engagement with a bracket 35 on the end of the rails 25, the member 21 being then moved back by the weight 30 to a position for attachment to a new piece of work ; this return movement is limited by a stop 37, adjustable on the table 11 to suit the length of the work, engaging a spring buffer 39 on the member 21. The member 21 may carry a cam device adapted to engage a switch lever 40 during the return movement to stop the machine automatically on completion of a seam. The usual feed of the machine is supplemented by a spiked endless chain 53 projecting through the table surface 11 to engage the work at one side of the feed-dog 4 in a line parallel to the seam and the rails 25, the work being stripped from this chain by plates 79 ; the chain is driven by a motor 60 by means of a sprocket chain 63 and gearing 70, the chain 63 also serving to drive the sewing-machine mainshaft 8, so that the chain 53 is synchronized with the machine feed. A guard may be attached to the stop 37 to cover the spikes of the chain 53 in the neighbourhood of the pins 29 to prevent injury to the operator when impaling the work on the pins. U.S.A.
