Abstract: 938,412. Coated fabrics; laminates. ARMSTRONG CORK CO. Jan. 20, 1960 [Jan. 22, 1959], No. 2049/60. Class 140. A surface covering material having an embossed appearance comprises a backing and a decorative wearing surface affixed thereto comprising fused particles of polymerized vinyl chloride resin having a specific viscosity of from 0.1 to 0.6, at least 5% by weight, e.g. 5 to 10% by weight, of the particles having a specific viscosity different from that of the balance of the particles by at least 0.12. The material may be formed by depositing the particles on to the backing which may be coated with an adhesive, e.g. an acrylic adhesive and subjecting the particles to heat and pressure whereby said particles fuse together to form a coherent decorative wearing surface affixed to said backing, having an embossed appearance. The polymerized vinyl chloride resin may comprise polyvinyl chloride, vinyl chloride-vinyl acetate copolymer which may comprise a mixture of copolymers having differing specific viscosities and containing different amounts of vinyl acetate therein, a mixture of polyvinyl chloride and vinyl chloride-vinyl acetate copolymer, or a vinyl chloride-vinylidene chloride copolymer. Suitable backings include burlap, beater saturated felted sheets, felted sheets after-saturated with asphalt or a suitable resin, and asbestos sheets. The surface covering material may be produced by forming a sheet of the particles by calendering and laminating the sheet to the backing with or without the aid of an adhesive. The particles may be of different shapes and particles of different specific viscosities may be deposited in areas to form a patterned surface. Specification 938,411 is referred to.

[Also in Group XL (b)] To facilitate the aural monitoring of telegraph signals, e.g. Morse, in the presence of unwanted signals on adjacent frequencies use is made of the binaural effect. The operator adjusts his receiver to give the signals to be monitored at a suitable audio frequency, and the audio output of the receiver is fed through separate channels to the ear-pieces of the operator's headphones. The channels are arranged to have differing delay-frequency and/or gain-frequency characteristics but to produce like outputs at the chosen audio frequency. In this manner, at that chosen frequency the signal appears to come from a source directly in front of the operator, whereas higher or lower frequency signals appear to originate to one side or the other of the operator. The Specification describes several forms of delay line.

Title: Improvements in or relating to the production of cotton yarns and fabrics having resistance to water and chemicals
IPC: D06M15/11
Filed: 1955-01-27
Abstract: 777,877. Proofing permeable materials; coated fabrics. COMMONWEALTH ENGINEERING CO. OF OHIO. Jan. 27, 1955, No. 2508/55. Class 140. Cotton yarns or fabrics of high water and chemical resistance are produced by impregnating or coating them by immersion in a dextran solution, treating the dextran-impregnated material with alkaline solution of an alkylating agent and heating the so-treated material at above 100‹ C. to complete the reaction between the dextran and the alkylating agent. Yarns may be subjected to stretching during the heating. The dextran may be dissolved in water or solutions of sodium hydroxide, sodium carbonate or dilute acetic hydrochloric or sulphuric acids. The alkylating agents include organic halides such as methyl, ethyl, propyl, isopropyl or benzyl halides; alkyl sulphates such as diethyl sulphate, tri-ethyl phosphate and aryl sulphonic alkyl esters such as the ethyl ester of p-toluene sulphonic acid. In examples: (1) a cotton yarn 3 from a bobbin 4 is guided by multi-grooved rollers 6 and 7 through a bath of a solution 2, comprising dextran, sodium hydroxide and water. The roller 7 is driven at a speed about 30 per cent faster than the roller 6. The yarn then proceeds into a bath 9 containing a solution of benzyl chloride and sodium hydroxide in water, and after multiple passes around the rollers 20 and 21, passes through a conical die 13, which removes excess solution, and an oven 12, before being wound into a coil 18. The oven 12 is maintained at about 130‹ C. to 140‹ C., and contains grooved rollers 14 and 15, the roller 15 being driven about 30 per cent faster than the roller 14 and being provided with grooves of progressively increasing diameter to facilitate stretching of the yarn. In Example (II) a cotton fabric is coated, using a similar dextran solution, and an alkylating solution containing diethyl sulphate, sodium hydroxide and water, and a heating temperature of 100‹ to 115‹ C. U.S.A. Specifications 2,203,702, 2,344,179 and 2,385,553 are referred to.

Class 100 (1). Sheets, postal envelopes &c. in a stack Z urged upwardly against an endless belt S are separated sequentially by the belt and fed past a friction roller F towards a co-operating endlessbelt T. The roller F is coupled through a friction slip-clutch to a drive means which tries to drive the roller in a counterclockwise direction, but when the roller engages the belt S, or there is only one sheet between them, the clutch is overcome by the friction force exerted by the belt, and slips, and the roller is driven clockwise. If, however, two superimposed sheets are separated by the belt S, as shown, the friction between the two sheets is not sufficient to overcome the clutch, and the roller F is driven in a counterclockwise direction to force the second sheet back, or hold it, until the top sheet has been separated. The slip-clutch can be adjusted to suit the nature of the sheets &c. to be separated.
