Title: Improvements in or relating to teleprinter exchange systems
IPC: H04L12/06
Filed: 1938-10-25
Abstract: 520,548. Teleprinter exchange systems. STANDARD TELEPHONES & CABLES, Ltd. (Haigh, L. B., and Clemens, P. J.). Oct. 25, 1938, No. 30851. Divided out of 518,241. [Class 40 (iii)] In transmitters of permutation codes comprising two commutators acting in series as described in Specification 518,241, the first commutator does not determine the code in toto, but repeatedly selects in turn the conductors of a group determining the code, each rotation of the commutator effecting the transmission of only one character of the code, instead of the whole code. Moreover, the second commutator, instead of operating by closing a circuit, operates by opening a circuit removing a short-circuit from a polarized relay. As shown, the second commutator is a cam IMP rotating at 3,000 revs. per minute and geared to a shaft DCS rotating at one eighth that speed. The shaft DCS carries a bank of cams SW, ST, and U1 ... U5, and these cams cooperate with relays and a selector switch a ... f as follows. Operation is started by the closing of a key SK, which causes a relay Mcr to close the circuit of a motor M driving the cams. At each rotation of the cam SW, an electromagnet SM rotates the selector switch one step. At each step, the ,cams Ul ... U5 operate in succession in series with the cam IMP to send'out a signal through a relay Tr to the exchange circuit R corresponding to a code depending on the polarities of the contacts of a ... e at that stage. The contact imp of cam IMP opens for 5 milliseconds during the operation of each cam U1 ... U5 in succession and this removes a short circuit from relay Tr and a holding on relay Hr associated therewith, thereby enabling the code signal to go through to the exchange circuit R. The contacts of switch f serve to control relays Sr, Tpr, and Mcr to set them for transmission when the key SK is closed and to stop the transmission when the cycle is completed. The cam commutator device IMP, imp may be replaced by a brush contact commutator.

Title: Process for producing patterned weaving effects
IPC: D06Q1/02
Filed: 1926-12-06
Abstract: 262,477. Heberlein & Co., Akt.-Ges. Dec. 5, 1925, [Convention date]. Inkless printing by chemical reaction; printing with special materials; resist printing.-Patterned effects are produced on fabrics by weaving them with nitrated vegetable fibres and then treating the fabric locally with an alkali whereby the nitrated threads can be removed by subsequent heating and steaming. The invention is applicable to fabrics of artificial silk, and to mixed fabrics comprising vegetable and animal fibres and artificial silk. The nitrated threads may also consist of artificial silk containing cellulose. The alkali may be applied directly as a thickened solution by printing, or the fabric may be printed with a reserve and then passed through an alkaline solution. In a modification, a denitrating agent is printed on the fabric, or the fabric is reserved locally, and passed through a denitrating solution, the fabric then being treated with the alkaline solution. The nitration may be effected by sulphuric and nitric acids, or by nitric acid alone. After fabrics have been treated with alkali and nitrated threads have been removed, the remaining nitrated threads may be treated with a denitrating agent to render the fabric unaffected by alkalis.

Patent GB-823174-A (GB)
Title: Improvements in or relating to the formation of crystalline films
IPC: B29C48/08
Filed: 1957-10-03
Abstract: Flat film of normally crystalline organic polymer, particularly of polyoxymethylene, is formed by casting a molten film of the polymer on to a moving metal surface, such as the peripheral surface of a rotating drum, maintained at a temperature which is both effective to cool the molten film to a temperature below the optical freezing point of the polymer and also sufficiently high to cause the molten film to stick to the surface upon initial contact, drawing the film off the surface after it has partially solidified and no longer adheres to the surface and thereafter quenching the film to complete its solidification.  In an example, polyoxymethylene of the type described in Specification 753,299 is extruded at 220 DEG  C. through a slot-shaped orifice on to the peripheral surface of a rotating stainless steel drum, the surface of which is maintained at about 141 DEG  C.  The extrusion orifice is about one inch from the surface of the drum and the film is maintained in contact with the drum over an arc subtending an angle of 90 degrees.  The film is then continuously stripped from the casting surface and passed through a 6 inch air gap into a 1% aqueous solution of polyvinyl alcohol at 10 DEG  C.  The process avoids curling and wrinkling of the film due to uneven shrinkage on cooling.
