Title: Improvements in or relating to the incorporation of elastic filaments, or threads in textile fabrics, or other articles
IPC: D02G3/32
Filed: 1935-07-06
Abstract: 459,508. Elastic threads and fabrics. WARNE & CO., Ltd., W., India Rubber Mills, Barking, and GRIFFITHS, J. P., 7, Hockley Drive, Gidea Park, both in Essex, and PINNELL, C. R., Foleshill, Beacontree Avenue, Walthamstow, GLADSTONE, F. R., 28, Wynndale Road, South Woodford, and COLE, L. V., 7, College Road, Winchmore Hill, all in London. July 6, 1935, Nos. 19364, 21857, and 28931. [Classes 120 (iii) and 142 (iv)] Elastic threads for use in the manufacture of textile fabrics and other articles are associated with relatively non-extensible linear elements arranged longitudinally therewith and adhering or fastened by their exterior to the exterior of the elastic elements, the substance of the non-extensible elements being so selected that they may be selectively disintegrated and removed from the fabric or article ; the elastic thread may be under any desired tension. The non-extensible element may be secured to the elastic thread by passing them together through a liquid capable of temporarily rendering the surface of one or both of the elements tacky and bringing the elements into contact to cause them to adhere together, e.g. a rubber or other elastic filament with a filament of cellulose acetate is passed through a bath of acetone, a portion of the cellulose acetate being dissolved by the acetone and, on drying out, binding the two filaments together ; other cellulose derivatives may be used and the solution may contain a plasticizer. A filament of a cellulose derivative may be freshly spun and united to the elastic filament whilst the former is still plastic or sticky, and the elastic filament may also be freshly spun. When a textile article is made from these composite threads it is immersed in acetone or other suitable solvent for the non-extensible element, leaving the rubber free to extend. In another method a stretched or unstretched rubber filament and a filament made from a cellulose derivative are secured by a covering of textile yarn which covering must be permeable to the solvent for the non- extensible element or otherwise permit access of the solvent thereto. In a further method the composite threads are formed by attaching a sheet of a soluble cellulose ester or ether to a sheet of rubber by wetting one or other of the sheets with a solvent so that the sheets adhere and then cutting the compound sheet into threads or a solution of the cellulose ester or ether may be spread on the rubber and the solvent allowed to dry out ; the article made from the composite threads is treated with a suitable solvent for the non-extensible elements. Specifications 423,997 and 436,674 are referred to.

Title: Improvements in receivers of electric waves
IPC: G01S3/08
Filed: 1920-07-08
Abstract: 147,700. Ges. f³r Drahtlose Telegraphie. June 3, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Directive wireless signailing; acrials. - In receiving systems for direction-finding, of the type using a rotating loop aerial combined with an amplifier, the capacity effect between the aerial and the earth is intensified and utilized to increase the amount of energy absorbed, and the asymmetry produced thereby is counteracted by loose coupling in the receiver or by the use of a secondary circuit. To intensify this capacity effect, one or both ends of the aerial or one or both leads to the amplifier are earthed or connected to a large capacity through condensers or high-frequency resistances, or connected together by these means and the centre point earthed. The asymmetry produced may be abolished by varying the capacities or the resistances. Direction without the customary ambiguity of 180 degrees can be determined by placing an absorbent system, consisting of a metal screen, syntonized coil or the like, on one side of the loop aerial. If the screen lies between the aerial and the transmitter, the minimum becomes indefinite. The screen may be coupled with the mechanism rotating the aerial so that the true direction can he read directly by the pointer on the rotating aerial.

Title: Electrically pumpable feedback solid-state diode laser
IPC: H01S5/12
Filed: 1975-05-13
Abstract: 1513573 Semiconductor Lasers XEROX CORP 13 May 1975 [22 Aug 1974] 20027/75 Headings H1C, H1K In a heterostructure semiconductor laser, the need for resonator reflections is avoided by producing Bragg scattering feedback from a periodic grating forming a heteroboundary 5, Fig. 1alpha, of the light waveguide region 2, the spacing of the grating perturbations being an integral number of half wavelengths of the generated radiation. In addition to the conventional laser output obtained in the plane of the waveguide region, lower order Bragg scattering radiation may also be emitted from one or both major surfaces of the semiconductor. As shown in Fig. 1, a single heterostructure laser comprises an n-type GaAs substrate 1 on which the periodic grating is formed by interferometric exposure of a photoresist material to a divided beam from an argon laser, followed by ion implantation, ion milling, diffusion, etching or surface milling. A p-type layer 3 of GaAPAs and a p-type layer 4 of GaAs are then successively deposited by liquid phase epitaxial growth. Subsequently the zine p-type dopant is driven into the substrate to form a p-n junction 6 and the light waveguide region 2 by heating in an evaporated diffusion capsule. Electrodes 7 and 8 of tin and gold, and of titanium, platinum and gold, respectively, are applied by sputtering and annealing. A double heterostructure laser is shown in (Fig. 4) which is similar to Fig. 1 but with an additional layer 10 of n-type GaAPAs providing a p-n function 6 and a second heteroboundary for a GaAs light waveguide region 2. During manufacture this region is doped with germanium or is initially undoped. The p-type dopant may be zine or cadmium.
