Title: Improvements in or relating to wearing apparel having permanent creases therein
IPC: A41D1/10
Filed: 1946-01-07
Abstract: Strips of material for use in forming permanent creases in garments, to which they are applied by heat and pressure, consist of strips of fabric of a non-thermoplastic nature, but containing thermoplastic material.  These strips may be formed by coating a cotton fabric on one side with a solution containing 10 parts by weight of the resin obtained by the copolymerization of 40 per cent vinyl acetate and 60 per cent vinyl chloride, 20 parts of acetone, 10 parts of butyl acetate, 4 parts of ethyl lactate, 3 parts of methoxy glycol acetyl ricinoleate and 3 parts butoxyglycol phthalate.  The fabric is dried at 90 DEG  C. and cut into tapes which are applied to the garment creases by pressure at 130 DEG  C.  In another example, a fabric consisting of plasticised polyvinyl acetate warp fibres and cotton weft fibres is assembled with a cotton fabric.  An aqueous acetone solution containing approximately 40 per cent of acetone is applied to the cotton fabric and the assembly united under pressure at 50 DEG to 60 DEG  C. and subsequently cut into tapes.  In a further example, a fabric is formed containing 40 per cent of filaments of cellulose acetate incorporating a water-insoluble plasticiser such as diethyl phthalate or dimethyl phthalate and 60 per cent of cotton fibres, woven so that the cellulose filaments are exposed on the back only. The fabric is cut into tapes and applied to the garment by heat and pressure during which process a volatile solvent and plasticiser may be present, a suitable mixture being 92 per cent acetone and 8 per cent diethyl phthalate.  Alternatively, a latent solvent may be employed, e.g. ethyl alcohol or methyl alcohol. This solvent may be used in an aqueous solution, a suitable mixture being 70 per cent ethyl alcohol, 22 per cent water and 8 per cent triacetin.

Title: Improvements in or relating to television receivers
IPC: H04N5/10
Filed: 1946-01-08
Abstract: 621,494. Pulse discriminating circuits. LAWSON, D. I., LORD, A. V., and PYE, Ltd. Jan. 8, 1946, Nos. 672 and 12752. [Class 40 (vi)] [Also in Group XL (b)] In a television receiver wherein interfering pulses at the line scanning frequency occur during the framing periods, means are provided for applying pulses at the line scanning frequency to the frame synchronizing channel so as to counteract the effect of the disturbing pulses on the frame synchronizing circuits. A television signal wherein the interfering pulses P may be the pulses carrying sound intelligence as described in Specification 621,479, is applied to the grid of a valve V1 through a condenser-resistor network such that the level B is brought to the valve cut-off potential and the signal appearing at the anode of V1 comprises the synchronizing and pulse signals only. As is described in Specification 620,478, the line synchronizing pulses cause the anode potential to fall for a short time, cutting off the diode D1 and causing the condenser C1 to discharge to a certain extent before the diode conducts again, while the frame synchronizing pulses cause the condenser C1 to discharge for a longer time sufficient to allow the diode D2 to become conducting and a pulse to be transmitted to the frame synchronizing circuit through transformer T. The presence of interference pulses P causes the diode D1 to conduct for short periods during the synchronizing intervals, thereby preventing the consistent operation of the circuit. To overcome this defect, negative pulses from the line scanning oscillator circuit, timed to occur simultaneously with the pulses P are injected into the circuit through the condenser C2. Alternatively, positive pulses timed to occur simultaneously with the pulses P may be injected into the circuit through the condenser C1 or by application to the grid of valve VI. The invention may be used in systems employing interlaced scanning in order to eliminate the interference which would otherwise be produced as a result of the alternately occurring different phase relationships existing between the frame synchronizing pulses and the line synchronizing pulses and thus also between the frame synchronizing pulses and the pulses P.
