Abstract: 885,495. Circuits employing bi-stable magnetic elements. SIEMENS & HALSKE A.G. Feb. 24, 1958 [Feb. 22, 1957], No. 5933/58. Class 40 (9). To avoid spurious outputs, a read winding a-a of a magnetic storage matrix runs through pairs of adjacent cores M in a direction parallel to the corresponding X control conductor. As shown in Fig. 2, the pulses (indicated by arrows) induced in the read winding by a partial read pulse in a single Y control conductor II cancel in pairs. As shown in Fig. 3, the pulses induced in one pair of the four cores on a single X control conductor 3 cancel the pulses induced in the other pair. Spurious pulses induced by inhibiting pulses in a further control conductor Z, Fig. 4, also cancel. The read winding may be linked through a number of matrix planes in a similar manner.

Abstract: 473,021. R u b b e r - cored yarns. SHEPHERD, T. L. Feb. 28, 1936, No. 6003. Drawings to Specification. [Class 120 (iii)] Yarn is formed from a thread of rubber, in which a sufficient quantity of an extensibility-reducing agent is incorporated to render it substantially inelastic, by covering it with a braiding or helical winding of a natural textile or artificial silk thread of such tightness that grooves or indentations are formed therein to prevent slipping, but are insufficient substantially to weaken it. In addition to the textile covering, a winding of a soluble filament or tape may be applied. The thread may be so treated that the extensibility-reducing agent is partially insoluble. After the yarn is made into fabric, the extensibility-reducing agent may be removed by boiling in water or otherwise dissolving, which also removes any winding of soluble filament or tape. The boiling-bath may also be a dyeing bath. Specifications 419,021, 447,972, 448,098, 449,314, 449,462; 459,434, 467,083, [both in Group V], and 469,433, are referred to in the Complete Specification ; and Specifications 440,256; 441,465, 442,931, 442,935, 442,936, [all in Group V], 442,937; and 443,284, [Group V], are referred to in the Provisional Specification.

Title: Improvements in distributing valve means for elastic pressure fluid driven percussion tools
IPC: B25D9/20
Filed: 1955-03-03
Abstract: 767,167. Engine valve gear. ATLAS COPCO AKTIEBOLAG, [formerly AKTIEBOLAGET ATLAS DIESEL]. March 3, 1955 [March 23, 1954], No. 6320/55. Class 122 (2). A piston-type percussion tool operated by pressure fluid such as compressed air has an annular sliding valve member 17 with a flange 20 seating either on a surface 18 or a surface 19 and the member 17 is raised to engage the upper surface 18 and supply air to the chamber 14 on the return side of a piston 10 by a thrower member 28 having an undersurface 37 in communication through a passage 35 with the chamber 15 on the working side of the piston; the thrower member may slide on the valve member or be secured to it by a press-fit or other means. With the valve member in the position illustrated, air from the main inlet valve 33 and a chamber 32 passes through the annular space 30 into the chamber 15. When the piston has moved down sufficiently to uncover the passage 35, the pressure in the chamber 15 acts on the thrower member to raise it against an abutment 45 on the valve member and so close the supply to the working chamber and open the supply to the return chamber through a passage 42. After uncovering the passage 35, the piston continues downward under expansion of the air until it uncovers an exhaust port 16. On the return stroke, an annular passage 43 in the piston vents the passage 35 to the exhaust port 16 and the compression of the air above the piston, acting on the effective surface 46, moves the valve member to the lower seat 19. A rifle bar 12 engages a nut 11 on the piston and, at its upper end, co-operates with a pawl and ratchet mechanism 9.

Title: Production of transparent polyamide structures
IPC: D06M13/144
Filed: 1943-04-23
Abstract: A structure, composed of a film or film-forming synthetic linear polyamide having a quench index above 125 mils, and being opaque by reason of the presence of voids is rendered transparent by treating it, while water-wet, with a non-reactive, non-aqueous liquid at a temperature not less than 75 DEG  C. and not more than 10 DEG  C. below the temperature at which the liquid will completely dissolve or melt the polyamide.  Preferably an interpolyamide from hexamethylene diammonium adipate and hexamethylene diammonium sebacate is employed, the proportion of the former constituent being 15-45 per cent of the whole.  They may be used as solutions in metal salt alcohol solvents as described in Specification 563,078, or in other solvents. Suitable non-aqueous liquids are glycerine, white oil, aniline, higher alcohols, e.g. n-hexyl alcohol, Dowthern heating fluid (a mixture of diphenyl and diphenyl oxide) or Wood's metal.  Suitable articles for treatment are films, yarns, fibres, rods, tubes or plates.  Films may be dried under considerable tension to avoid crinkling.  Examples describe the treatment of films produced from an interpolymer containing 3 per cent hexamethylene diammonium adipate and 70 per cent hexamethylene diammonium sebacate dissolved in 500 parts of calcium chloride and 1500 parts of methanol.  Methanol is removed by evaporation and calcium chloride with tap water.  The opaque film while still wet is treated for about 3 seconds at 140 DEG -145 DEG  C. in glycerol, for a few seconds at 140 DEG -145 DEG  C. in white oil, or for a few seconds at 90 DEG -100 DEG  C. in aniline. The treating liquid is washed away with a suitable solvent and the film dried under tension.  Directions for determining the quench index of a polyamide are given in the Specification.  Specifications 461,236, 533,967, 542,509, and U.S.A. Specifications 2,071,250 and 2,130,948 also are referred to.
