Title: Improvements in or relating to the production of rubber thread
IPC: B29D99/00
Filed: 1933-03-31
Abstract: 397,419. Rubber threads. INTERNATIONAL LATEX PROCESSES, Ltd., 10, Lefebvre Street, St. Peter's Port, Guernsey.-(Assignees of Joss, E. J.; 875, Hope Street, Bristol, Rhode Island, U.S.A.) March 31, 1933, No. 9713. Convention date, April 16, 1932. [Class 70.] Rubber thread of reduced cross-sectional dimension is made form thread of greater cross section by stretching the unvulcanized or partly vulcanized thread and then partially or wholly relieving the stresses produced while still in the extended condition, preferably by the action of heat. The thread may be produced initially in any known manner. The reducing process may consist of stretching so that the cross-sectional area is smaller than desired, partly removing the stresses, and then allowing the thread to retract ; or of stretching further than desired, partly removing the stresses, allowing to retract so that the cross section is the desired size and then relieving the remaining stresses. After the reducing process the thread is passed through drying chambers which simultaneously vulcanize it if vulcanizing ingredients were included in the original mix. In an example thread T is delivered over rollers 1, 2, through the bath 3, over the stretching roller 4, on to the conveyer 5, over the retracting roller 7 and finally collected on the conveyer 9. The stretching is effected by roller 4, and also if desired bv roller 2, by these rollers rotating at a higher speed than roller 1. Roller 7 rotates at a slower speed than roller 6 and hence allows the thread to retract and be deposited on conveyer 9 without tension.

Title: Improvements in furnace control
IPC: F23N1/00
Filed: 1919-04-17
Abstract: 147,295. McLean, E. April 17, 1919. Air-supply, regulating; mechanical stoking. - In a boiler furnace provided with a regulating- device for maintaining a constant pressure in the furnace chamber, the fuel-feed is controlled in accordance with the variations in position of such regulating-device. Means for varying the forced draught supply inversely as the boiler pressure are also described. Fig. 1 is a diagrammatic general view. The flue damper 13 or other means, such as an induced-draught fan, by which the furnace pressure is determined, is controlled by a pressure fluid-relay device comprising a chain 14, piston 16 and piston valve 21 operated by a swinging plate 28, Fig. 1, exposed on one side to the atmosphere and on the other to the furnace chamber pressure. The steam valve 42 of the engine 40 driving the forced-draught blower is controlled to vary the speed of the blower inversely as the boiler pressure by a pressure relay device comprising the chain 57, piston 55, and relay piston-valve 64, the piston and piston valve being interconnected with each other and the rod 70 of the steam-pressed diaphragm 46, by the lever 74 pivoted at 75 and the floating lever 71. Instead of the fan, a valve in the air duct may be similarly controlled. The steam supply to the stoker engine 9 is controlled from the piston 16 through the chain 109 and cam 107 engaging a lever 94 forming part of a governor connected to the steam valve 82. The valve 82 is secured to a spindle 94 on which slides a sleeve 85, Fig. 6, positioned by the governor balls and connected to a frame 96 in which is mounted at 95 the lever 94 in toothed engagement with a rack 92 on the valve spindle. The surface of the cam, which acts as intermediary between the piston 16 and the lever 94 and thus determines the position of the spindle 84 within the sleeve 85, is made up of pins 107 adjustable in radial slots in the cam frame and in practice the correct positions of the pins to give the desired control of the fuel supply are found by trial. Specification 11848/05 is referred to.

Title: Manufacture of pigment colours
IPC: C09B63/00
Filed: 1932-04-06
Abstract: Coloured pigments from vat-dyestuffs are manufactured by precipitating the dissolved leuco-derivative of the dyestuff by means of an alkali, alkaline-earth or heavy metal silico-aluminate and oxidizing the precipitate.  The alkali silico-aluminate may be made by precipitating an alkali aluminate solution by means of a dilute lukewarm alkali silicate solution, or preferably in the vat itself by adding to the vat successively an alkali aluminate solution and an alkali silicate solution.  The alkaline-earth and heavy metal silico-aluminates are made by double decomposition from an alkali silico-aluminate.  The proportion of alkali silico-aluminate or of alkali aluminate employed may vary within wide limits depending upon whether the compound is to act simultaneously as a substratum and an extender.  In examples: (1) a sodium aluminate solution (prepared from aluminium sulphate solution and caustic soda solution) is added to a hot vat (from a vat dyestuff such as indigo or a halogen indigo, caustic soda and sodium hydrosulphite), the mixture is precipitated by means of sodium silicate solution and the product filtered or preferably oxidized, e.g. by means of air; (2) a sodium aluminium-silicate (from aluminium sulphate, caustic soda and sodium silicate) is added to an aqueous solution made by vatting dibenzanthrone, the precipitate being worked up as in (1); (3) to a sodium aluminate solution (prepared as in (2) but with a slight excess of caustic soda) is added N-dihydro-1 : 2 : 1<1> : 2<1>-anthraquinone-azine or a halogen substitution product thereof, vatting is carried out by means of sodium hydrosulphite, the mixture is precipitated by adding sodium silicate solution and the precipitate worked up as in (1).  Other pigments may be similarly prepared from vat dyestuffs of the indigo, thioindigo, naphthioindigo, anthraquinone, pyranthrone, anthanthrone, violanthrone, isoviolanthrone and naphthalenetetracarboxylic acid series.

Filed: 1991-01-09
Abstract: PURPOSE:To attain efficient operation even at a light load being in the standby state by devising the equipment so that the ON-period depending on a synchronization oscillation circuit is switched in two ways in response to the state of the load. CONSTITUTION:The equipment is provided with capacitors 55, 56, transistors(TRs) 57, 60, an emitter resistor 58, a photocoupler 59, a drive resistor 61 and a base resistor 62. When the standby state is set, switch means 41, 43 are opened by control signals 40, 42 from a microcomputer 39. Moreover, in order to improve the efficiency of the equipment when only the microcomputer 39 is a load, a control signal 63 is set to an L level, the TR 60 is turned on through the base resistor 62 and the information is sent to a primary side through the photocoupler 59. The primary winding receives the information to turn off the TR 57. In this case, the available power of the power supply is reduced, but a loss of the resistive component of a primary winding 6 and a secondary winding 18 of a switching transformer 5 is reduced and the capacitance of the oscillation capacitor by the microcomputer 39 is reduced.
