Title: Improvements in and relating to the manufacture of rubber threads
IPC: C08J5/02
Filed: 1934-09-18
Abstract: Relatively inextensible rubber thread is made by incorporating casein, albumen, or other substances which form water-soluble films with a coagulable rubber dispersion and coagulating the dispersion, e.g. by extrusion into liquid coagulant. The inextensibility of the thread, or yarn spun or fabric woven or knitted from the thread may be removed by treatment with hot water containing dyestuffs, which treatment dissolves out the casein &c., thus restoring extensibility, and dyes and vulcanizes the thread. The dispersion may contain also viscose or cellulose, in which case the extensibility is not fully restored. Specifications 442,931, 442,935, 442,936, 443,284, 447,973; and 448,098, [Group V], are referred to.ALSO:Relatively inextensible rubber thread is made by incorporating casein, albumen, water-soluble natural and synthetic gums and resins, cellulose esters and ethers, sodium silicate, sugar or other substances which dissolve in water to give solutions miscible with latex without coagulation and on evaporation yield a coherent water-soluble film, with a coagulable rubber dispersion and coagulating the dispersion, e.g. by extrusion into liquid coagulant. Glue or gelatine may be used but only in combination with casein &c. The casein &c. may be added to the dispersion or coagulant or both.  The inextensibility of the thread, or yarn spun or fabric woven or knitted from the thread may be removed by treatment with hot water to dissolve out the casein etc.; this dissolving-out-e.g. with hot water containing dyestuffs-may also vulcanize and dye. The inextensible thread may be steamed with simultaneous stretching, dried, and then in the stretched inextensible condition woven or knitted with other textile fibres into fabric-e.g. lace-before dissolving out.  The rubber dispersion may contain also viscose or cellulose, in which case the extensibility cannot be fully restored.  Glycerine to prevent the outer surface of the thread becoming brittle when dry and linen or cotton fibres.  Two examples are given in which methyl cellulose plus casein and glue plus casein are used as the "extensibility - reducing agents."  Specifications 442,931, 442,935, 442,936, 443,284; 447,973, [Group IV], and 448,098 are referred to.

Title: Improvements in or relating to cathode ray tube television and like apparatus
IPC: H04N3/20
Filed: 1937-10-11
Abstract: 505,490. Television. WHITE, E. L. C., and FAUDELL, C. L. Oct. 11, 1937, Nos. 27657/37 and 2084/38. [Class 40 (iii)] A cathode-ray is cut off if either deflecting force fails. The current passed by a controlling valve V4 is regulated by potentials derived from scanning oscillators V1, V3. An additional winding 10 on the frame scanning transformer TF supplies current through a rectifier 11 to a load resistance 12. The potential across this resistance is applied through a filter 14, 15 to the controlling grid of the valve V4, and, if the scanning currents decrease, the anode current so decreases that a coil 4 releases a contact 3 to break the mains supply to the cathode-ray tube CR. The current for the coil 4 and the valve V4 is obtained from the potential developed across a resistance 16 in a resonant return circuit 17, V2, 19, which, in conjunction with a valve V1, produces the line-scanning oscillations as described in Specification 400,976. If these oscillations fail, the current through the valve V4 is insufficient to maintain the relay 3, 4 closed. This decrease in anode current also renders a valve V5 conducting to discharge a high-tension lead 9 to the cathode-ray tube. According to modifications, both scanning oscillators affect the grid circuit of the control circuit of the controlling valve, which has a separate high-tension supply and cuts off the high-tension supply to a transmitting cathode-ray tube through two relays in series, Fig. 2 (27557/37) (not shown) ; potentials derived from the scanning circuits are applied respectively to two controlling grids of a a hexode, which controls a relay to disconnect the high-tension supply to the cathode-ray tube and discharges the high potential on the accelerator or first anode of the tube, Figs. 1 and 2 (2084/38) (not shown) ; rectified outputs from sources of line-frequency and framing-frequency signals are applied through resistances to the grid of a double-diode triode with the relay 3, 4 in its anode circuit, and the diodes limit the maximum of the rectified outputs to the potential of the grid-bias battery, Fig. 5 (not shown). Specification 423,213 also is referred to.
