Title: Improvements in or relating to ribbons of foils, films or the like containing cellulose derivatives and to wires and other articles covered therewith
IPC: H01B7/02
Filed: 1935-08-08
Abstract: Talc or like solid unctuous substance is applied to ribbons of foil made of or containing cellulose derivatives, and the ribbons are then wrapped on electric conductors such as wires, cables, ribbons, bus-bars, and coils.  The solid lubricant does not impart tackiness as is the case with oils, and it enables narrow ribbons of foil to be passed at high speed through the guides of the winding devices, and to be unwound from packages without sticking. Instead of talc, there may be used a metallic salt of a fatty acid such as zinc stearate or palmitate, or aluminium oleate, or bismuth oxychloride, or fuller's earth.  The solid lubricant may be applied by rubbing, dusting, or blowing on to the surface of the foil.  The quantity deposited is preferably so small that the transparency is not materially affected and subsequent cementing or welding is not interfered with.  The foil may be of cellulose nitrate, acetate, formate, propionate, or butyrate, or of methyl, ethyl, or benzyl cellulose.  The foil may be formed by extrusion or casting, or by block pressing and cutting. Wide sheets may be cut or otherwise divided into strips or ribbons. The foil may be coated with wax, resin, or other cellulose derivatives.  The foil may contain plasticizers, pigments, dyes, and fillers.  In an example, thin cellulose derivative foil, treated with talc or like solid lubricant, is split into very narrow ribbons which are then cross-wound on spools, cops, or the like.  A package thus formed is placed in a wire-wrapping machine and caused to rotate in a plane at right angles to the forwardly-moving electric conductor wire at a radial distance of several inches.  The wire may pass through a cellulose derivative lacquer, which serves as an adhesive, before being wrapped.  The ribbon is spirally wound round the wire in over-lapping arrangement and is firmly cemented thereon.  The wrapping of golf-club shafts, fishing rods, and tool handles with ribbons of foil is referred to.  The Specification as open to inspection under Sect. 91 comprises also the employment of cellulose derivative foil treated with solid lubricant for wrapping purposes in general.  This subject-matter does not appear in the Specification as accepted.ALSO:A solid unctuous substance, e.g. talc, a soap such as zinc stearate or palmitate or aluminium oleate, bismuth oxychloride, or fuller's earth is used to lubricate ribbons made of or containing cellulose derivatives to be used for wrapping purposes.

Title: Improvements in or relating to signal transmission systems
IPC: H04B3/20
Filed: 1935-08-09
Abstract: 461,079. Transmission systems. STANDARD TELEPHONES & CABLES, Ltd., and LATIMER, K. E. Aug. 9, 1935, No. 22520. [Class 40 (iv)] An arrangement for directing signals from an input channel I, Fig. 1, to an output channel 0 alternatively through paths of different characteristics makes use of a hybrid transformer H1 and a network N1 normally balancing one path so that there is no current flow in the second path. When, however, a large impedance is inserted in the first path at the point B, the balance is upset and the current flow is mainly through the second path. The impedance may take the form of a relay break contact, one or more rectifiers or a back-coupled amplifier. The two paths are coupled to the output circuit through a second hybrid transformer H2 and balancing network N2. The arrangement may be used for the insertion between the channels I, 0 of any desired network S, which may, for example, be a stabilizing network or a secrecy device. In the latter case, the impedance change at the point B may occur periodically. An application to directional switching in a two-way system is shown in Fig. 2 in which rectangles 1, 2 each represent the apparatus shown in Fig. 1, S being a loss network. It is assumed that there is -a break at the point B earthed on one side, so that earthing of the other side by contact 3 completes the path. Contact 3 is associated with a differential relay 4 controlled through four amplifier-detectors from two points in each transmission channel in the manner described in Specification 456,827.
