Patent GB-406230-A (GB)
Title: Loom warp guard
IPC: D03D51/20
Filed: 1933-09-30
Abstract: 406,230. Loom warp stop - motions. NIEMI, K. H. A., Hyvinkõõ, Finland. Sept. 30, 1933, No. 26977. [Class 142 (i).] Each lamina 3 of a warp stop-motion is provided with two holes 4, 5 through each of which one or more warp threads are passed, so that if one thread breaks, the lamina is supported only by the thread or threads in the other hole and relative movement between the lamina and a feeler 9 causes the lamina to assume an inclined position to effect the stopping of the loom by electrical or mechanical means. As shown, the lamina 3 of arcuate form, is arranged between supports 16, 17 for the warps and is provided with a projection 6 having limbs 7, 8 adapted to make contact with a bar 14 insulated from a carrier 9, 10, 11. The carrier may be stationary or be moved up and down to cause engagement of its projections 12, 13 with the lamina. When a warp thread breaks, the difference in the pressures everted by the projections 12, 13 is sufficient to cause the lamina to turn so that an electric circuit is completed through the bar 14 and one of the limbs 7, 8. If both threads break, the larger limb 8 causes the lamina to turn. A projection 18 on the lamina is adapted to engage on its upward movement with a projection 19 on the warp support, to counteract the turning effect of the warp friction in the holes 4, 5. Fig. 4 shows the method of threading two warps through one hole of a lamina. Neither thread breaks, the tension on the other is reduced, and the lamina turns.

Title: Production of composite electrical conductors including superconductive conductors
IPC: H01B13/00
Filed: 1974-06-19
Abstract: 1437277 Making superconductive conductors SIEMENS AG 19 June 1974 [22 June 1973] 27289/74 Heading B3 [Also in Division H1] A method of making a composite conductor including a superconductive conductor made of an intermetallic compound 5 includes providing a ductile core 1 having at least one element required to form the intermetallic compound with a sheath 2 of a ductile material comprising a metal containing a quantity of the or each remaining element required to form the intermetallic compound 5, surrounding the core and sheath by a layer 3 of a further material, providing the layer 3 with an external jacket 4 which is a good thermal and electrical conductor when the intermetallic compound is superconductive, reducing mechanically the overall cross-section of the core 1, sheath 2, layer 3 and jacket 4, and heat treating them to form the intermetallic compound, the layer 3 preventing diffusion of the constituents of the sheath 2 into the jacket 4. The core 1 is of Nb, the sheath 2 of C-Sn alloy in which the Sn is present in 8% atomic, the layer 3 is of Mo and the jacket 4 of C. They are worked into wire by drawing or rolling and heat treated in a vacuum or in a protective gas at 650-850 C. for about 30 hours. The Sn in the sheath 2 diffuses into the core 1 to form the layer 5 of Nb 3 Sn. To make a multi-core cable, Fig. 3 (not shown), single core conductors are made by pushing Nb rods (31) into Cu-Sn sheaths (32) and reducing their cross-section in stages with intermediate heat treatment between each stage. Eleven conductors are placed in a Cu-Sn tube (33), which is placed in a Ta tube (34) and then into a Cu tube (35). Eleven such assemblies are placed in a Cu tube (37), and the complete assembly is drawn down to wire, with intermediate heat treatment. A layer of Nb 3 Sn is formed on each Nb core (31) by heating at 700 C. for 20 hours in vacuo. V 3 Ga may also be formed as the superconductive material as Ta inhibits the diffusion of Ga. In this case a Va core in a Cu-Ga core is used, the Ga comprising 0À1-30% atomic, preferably 0À1-18%, of the sheath material. Heat treatment is carried out at 500-950 C. for 5 minutes to 100 hours depending on the Ga content and the thickness of the V 3 Ga required.

Abstract: 806,215. Woodworking. WST PATENTER A.B. Sept. 6, 1956 [June 6,1956], No. 27300/56. Class 145. A machine for lining the edges of slabs, for example, doors, with strips of veneer or other edging material comprises a veneer drum 5 on each side of a roller feed table 2, a rotary glueing device 7 for one side of each veneer strip, a pressing table 4 having screw-adjusted heated beams 10 and 11 one of which is movable by pneumatic cylinders 23 and a belt or chain 18 driven by a motor 16 and having dogs 21 for feeding the slab from the feed table to the pressing table, where the slab remains stationary until the glue has set, and then on to a collecting table 27. When the slab has been placed on the feed table and the veneer strips, which are turned to a vertical position by guides 24, have been attached to the forward ends of the slab edges, a switch 15 is actuated to start the motor 16 and cause the belt 18 to feed the slab and the veneer strips until the rear end passes a switch 22 which is operated to stop the motor. As the slab stops on the pressing table, the beam 11 is moved inwards to clamp the strips to the slab and remains in this positoni under the control of a time relay for a time sufficient to allow the glue to set. When the beam moves outwards again, it operates a switch 25 which restarts the motor 16 and starts two pairs of cutters 26 pressing on opposite sides of the slab so that the veneered edges of the slab are trimmed and then the veneers are pasted off as the slab is moved to the collecting table.
