Title: An electric heat sequence control
IPC: G05D23/275
Filed: 1970-06-24
Abstract: 1280910 Time switches CONTROLS CO OF AMERICA 24 June 1970 [7 July 1969] 30557/70 Heading H1N [Also in Division G3] In a space heating system a plurality of electric heaters are sequentially energized via switches which are closed by a bank of cams  driven by a synchronous motor the rotation of which is controlled by a thermostat responsive to the space temperature. The 1st cam stage 22 (Fig. 2) operates a control unit including a bi-metal strip thermostat 42 in series with the cam-shaft, drive motor 10 and movable between cold (C) and hot (H) positions. Thereby the motor 10 is energized if the thermostat calls for heat, via a step down transformer. The 2nd cam stage energizes a fan motor 48 (Fig. 3) and a solenoid after 5 degrees rotation of the cam. The 3rd, 4th, 5th, 6th and 7th cam stages (Fig. 6, not shown) switch on respective heaters at 10, 40, 70, 100 and 130 degrees rotation of the shaft, respectively if the thermostat bi-metal strip is still in engagement with contact H. If the thermostat still calls for heat when all the heaters are on, it is arranged that the motor supply and hence the cam-shaft rotation is stopped until the required temp. is reached. Whereupon the motor is started again and following 180 degrees rotation of each cam stage the heates are switched off sequentially. To prevent a plurality of heaters being switched ON simultaneously after a supply failure, the solenoid 54 is coupled to a lever 62, pivoted at 64 and having an extension 68. The lever 62 is in the position shown in Figs. 2 and 3 when the solenoid is energized. On supply failure the solenoid is de-energized and a spring 66 rotates the lever 62 so that the extension 68 lifts a projection of switch blade 38 (Fig. 2) and engages mutually the contacts of all three blades 38, 40, 36 so that the motor will commence rotation when the supply is restored and will rotate to drive the cam bank to its shut off point. At the same time the extension engages the switch blades of the cam stage 24 preventing energization of the solenoid and fan, and engages the switch blades of the heater switches preventing energization of the heaters, until the solenoid is energized.

Title: Improvements relating to materials having an irregular fibrous structure and low bulk density
Inventor: LARMAN WILLIAM THOMAS
IPC: D01D5/22
Filed: 1954-10-26
Abstract: A filament-forming substance is extruded into a coagulating liquid through a large number of closely spaced orifices and the mass of filaments so formed is withdrawn at a take-up speed which is less than half the extrusion speed.  The filament-forming substance may be a solution of cellulose acetate in acetone and the coagulating bath may be an acetonewater solution or water which may be at a temperature of 2 DEG  to 23 DEG  C. and from which metal cations may have been removed.  The spinning jet may comprise extrusion orifices arranged in one or more rows to produce a sheet or ribbon-like product or in an annulus to produce a tube or "collapsed" tube structure.  The orifices may be circular, elliptical, rectangular, slot-like or of a cross-section having re-entrant angles.  Some orifices may be of larger diameter than the others so that the ratio of the take-up speed to extrusion speed is above 0.8 to 1, thus giving a number of straight reinforcing filaments.  The orifices from which straight filaments are produced may be separately supplied with spinning solution at a lower pressure or the supply of solution to them may be restricted by providing shallower or longer supply channels. After leaving the coagulating bath the material may be compressed, or heated, or both, e.g. by passing between one or more pairs of heated rollers, or treated with a solvent or swelling agent or both, e.g. acetic acid or ethyl acetate, to effect mutual adhesion of the fibres.  Such solvent may also contain a cellulose ester or methyl cellulose, methyl ethyl cellulose or hydroxy ethyl cellulose. The filament-forming material may also be an acetic acid solution of cellulose triacetate, viscose or cuprammonium solutions, or a polyamide melt or hot solution of cellulose triacetate in cyclohexanone, which are extruded into quench baths.  The product may be used for decorating clothing, as a braid or cord, as an upholstery material or as a heat insulant. Specifications 795,445 and 796,544 are referred to.
