Title: Improvements in or relating to yarn and its manufacture
Inventor: PLACE JAMES ALFRED
IPC: D02G1/10
Filed: 1954-01-16
Abstract: 761,084. Crimping fibres and yarns. BRITISH NYLON SPINNERS, Ltd. Dec. 28, 1954 [Jan. 16, 1954], No. 1346/54. Class 120 (3). Continuous filaments or yarn comprised thereof consisting of a synthetic linear condensation polymer e.g. polyureas, polyurethanes, polyesters, polytriazoles, polyamides, are rendered " potentially crimpable " i.e. able to assume a crimped configuration on being relaxed, by continuously passing them over and in contact with one or more edges viz. the ridges of any sharply angular body such as a knife edge or a bar of rectangular crosssection, whilst under tension and at a temperature of between 15‹C below the melting point of the polymer and 100‹C so that the filaments are bent over or around the edge or edges through an angle. The yarn is subsequently allowed to relax before or after forming it into a composite yarn and/or further twisting and/or weaving or knitting into fabrics or manufacturing textile articles therefrom: relaxing may be assisted by heat and/or water or steam treatment. The filaments may be treated with swelling agents before, and a setting medium after, crimping. The filaments may be heated at the deforming edges by raising the temperature thereat, as by circulation of hot fluid e.g. steam, within a hollowed body of the material constituting the edges or by passing an electric current through the material, and preheated, as by passage through molten metal or over a hot metal surface. An inert gas e.g. nitrogen, steam, or carbon dioxide, may surround the filaments to prevent oxidative degradation thereof during heat treatments. Specification 558,297 is referred to.

Title: Telecommunication party line discriminator
Inventor: REANEY DONALD
IPC: H04Q5/24
Filed: 1969-01-10
Abstract: 1,235,654. Telephone exchanges. PLESSEY CO. Ltd. 24 Oct., 1969 [10 Jan., 1969], No. 1660/69. Heading H4K. A party line discriminator comprises metal oxide silicon transistors (MOSTs). As shown, there are two parties connected to a common line A, B. In the Figure references commencing with M refer to active Mosts and references commencing with R are passive Mosts connected to function as resistors. The circuit within broken line 3 is formed as a monolithic unit. If the 'X' subscriber lifts his handset and earths the A wire, by depression of a key or by operation of an additional hook switch contact, a portion 1 of the discriminator responds energizing relays X and S in series. Contacts X1 and X2 close to connect the A and B wires to the positive and negative wires of the line circuit (not shown) and a contact X3 connects the 'P' wire of that line circuit to the 'X' subscribers meter. Operation of relay S opens contacts S1 to S2 disconnecting in initial potential supply and the discriminator from the line A, B. Setting of a bi-stable M9-M10 starts a timer T and setting a bi-stable M29- M30 removes an inhibit potential i previously applied to the line circuit. The line circuit can now respond to the outgoing call and if the call is established before time out of the timer a signal returned from the exchange and arriving at c passes through an OR gate M18-M19 resetting the bi-stable M9-M10 and the timer. Earth applied to a point P of the portion 1 from the line circuit holds the relays X and S conducting for the duration of the call under control of the P wire. If, however, the timer times out before a call is established a signal passed by an OR gate M25-M26 resets a bistable M3-M4 causing the relays X and S to release. If a terminating call for the subscriber X arrives the line circuit responds marking terminals X and M of the discriminator. An AND gate M20 and M21 responds to the presence of both signals causing the relays X and S to connect the 'X' subscriber to the line circuit. Ringing can then be effected over the line pair. Connections for the subscriber 'Y' operate in the same fashion as those for the subscriber 'X' except that contacts Yl and Y2 of the relay Y cause a reverse connection of the line pair A, B to the line circuit wires.
