Abstract: 1,198,260. Seaming non-metallic sheet material; laminated polyolefin materials. S. TAKEDA, and I. NIWA. 4 July, 1967 [4 July, 1966; 8 Sept., 1966], No. 30827/67. Headings B5K and B5N. [Also in Division F2] Two longitudinal edge portions 2, 3 of a strip of synthetic thermoplastic polyolefin material, which is formed around a solid member 4 so that the portions 2, 3 overlap, are bonded together to form a cylinder using as a binder a synthetic thermoplastic polyolefin in a molten state. The polyolefin used as the binder is preferably the same as the polyolefinic material, e.g. polyethylene or polypropylene, which is in the form of a film or a fabric. The binder is applied at a temperature in the range of 240- 290 C., preferably 250-275 C. As shown, a continuous polyethylene fabric 1 passes over a guide roll 9 and folding guide plates 5 co-operate with a width adjusting plate 4 to cause the overlap of the portions 2, 3 of the fabric I. The molten binder 8 is applied through a nozzle 6 of a flow-adjustable applicator 7. Rollers 10 effect a preliminary bond between the portions 2, 3 and the binder 8 and cooling rollers 11 press and cool the preliminarily bonded portions. The rollers 11 may be cooled by water or brine cooled by refrigeration. The continuous flattened tube is cut into short lengths by a rotary cutter 12. In a modification (not shown), two or more pairs of cooling rollers are provided. Preferably, the fabric is woven in plain weave from polyethylene or polypropylene flat yarns, i.e. stretched tapes, and may have a polyethylene or polypropylene film laminated thereto.

Title: Device for measuring the eccentricity of coated or covered cables, wires and rods
IPC: G01B7/312
Filed: 1947-11-24
Abstract: 641,674. Magnetic tests of measurements. URMENYI, L. Nov. 24, 1947, No. 31123. [Class 37] Apparatus for determining the eccentricity of the magnetic core of a coated cable or rod, consists of a plurality of coils wound on iron cores mounted symmetrically round the cable and means for comparing the reluctances of the magnetic circuits formed by each iron core, the iron-cored cable and the gap between them. As shown, Fig. 1, four coils 1, 2, 3, 4 are employed, wound in two halves on the limbs of U-shaped iron cores 5, 6, 7, 8 assembled symmetrically round the cable 9. A primary winding 10 wound over the cable 9 and fed with A.C., induces voltages in each of the four coils, the magnitude of these voltages being a measure of the respective gaps. The U- shaped cores 5, 6, 7, 8 may be replaced by L- shaped cores with a circular laminated ring to take the place of the second limbs, the coils being wound on the single limbs only. The voltages in the coils 1, 2, 3, 4 may be fed separately to the grids of four valves 13, 14, 15, 16, Fig. 3, operating as anode bend detectors, the vertical coils 1, 3 feeding valves 13, 14 and the horizontal coils 2, 4 feeding valves 15, 16, so that any eccentricity, e.g. in the vertical plane, is shown by a difference in the anode currents of valves 13, 14, indicated on a meter 25. The valves may operate as grid leak detectors, or metal rectifiers may be used. The voltage inputs to valves 13, 14 and 15, 16 may be reduced by tapped resistances connected between the hot ends of coils 1, 3 and 2, 4, whereby the percentage change in voltage due to eccentricities is increased. In a further modification, Fig. 5, the amplified and rectified voltage difference between coils 1, 3 and 2, 4 separately indicate on meters 43, 44 the vertical and horizontal eccentricity respectively, and these voltages added to similar voltages derived from coils 1, 2 and 1, 4 show, on meter 47, the overall eccentricity. In the Provisional Specification the meter 47 may be a potentiometer whose voltage is fed to a gas-filled triode valve which may, at a predetermined eccentricity, operate an alarm or stop the machine producing the covered cable. The A.C. input to the coils 1, 2, 3, 4 may be supplied by a separate primary for each coil, connected in a series-parallel combination, or the coils 1, 2, 3, 4 themselves may be so connected to the A.C. source. For use on the bench only two coils may be used, and the cable rotated by hand to determine the plane and extent of the eccentricity.

Title: Improvements relating to time control mechanism for electric switch control apparatus
IPC: H02P1/16
Filed: 1923-12-17
Abstract: 218,922. James, H. V. Dec. 17, 1923. Retarding and time-limit devices. - An automatically operated control switch for timing the closure of a main switch is rotated against a spring by a motor which is set in action by depressing a button. After the required travel, the motor is unclutched by taking off a brake from an idle wheel forming part of an epicyclic transmission, and the control switch member is returned by the spring. In the apparatus shown in Fig. 1, a motor K started by a press-button switch C rotates the control switch member X through worm gearing 0 and differential bevel gearing N. A magnet T<3> keeps a brake S applied to the idle wheel until the member X has travelled on to the contacts G<2>, G<3>, which complete a circuit through the main switch closing magnet A and opens the circuit through the motor and brake magnet. The member X is then returned by its spring and cannot be actuated again until the main switch has opened. Visible and audible signalling devices may be actuated by magnet windings F', F<2>, G. The time element can be varied either by a regulator H in the motor circuit or by changing gear ratio of the transmission. In a modified arrangement, the apparatus is brought into action after the opening of the main switch to set a minimum time limit to the reclosure.

Title: Improvements in the separation of metal salts from their aqueous solution
IPC: B01D15/08
Filed: 1956-10-18
Abstract: Salts of metals whose standard potential is more negative than +0.4 and whose atomic number is not less than 29 are separated from aqueous solutions thereof, by contacting with polymeric hydrocyanic acid or hydrolysed polymeric hydrocyanic acid.  The effect of the polymer is adsorption and ion exchange, but is primarily chemical reaction.  Metals may be platinum, palladium, gold, silver, copper, mercury and lead, and chlorides are more readily absorbed than sulphates.  The solution may be passed through a column of polymer at normal or elevated temperature, and one or more metal salts may be preferentially adsorbed from a solution of a salt mixture.  After separation from the solution, the metal may be recovered from the polymer by washing with dilute acid or by destruction of the polymer by heating with concentrated H2SO4.  Examples refer to the treatment of solutions containing chlorauric acid, silver nitrate, lead acetate and chloroplatinic acid.  The hydrocyanic acid may be polymerized in aqueous solution in the presence of calcium hydroxide catalyst, and tablets may be formed by pressing, at 50-60 DEG  C., the vacuum-dried powder obtained by mixing polymeric HCN and a 50 per cent methacrylate resin emulsion.  The hydrolysed polymeric HCN is obtained by boiling the polymer for two hours with 30 per cent caustic soda to partially saponify the polymer and produce a product containing 28 per cent N2 compared with a starting polymer with 42-46 per cent N2. Specification 456,151 is referred to.
