Title: Improvements in or relating to means for operating electric discharge lamps
IPC: H05B41/232
Filed: 1949-06-18
Abstract: 669,655. Supply systems for space discharge lamps. EKCO-ENSIGN ELECTRIC, Ltd., and STICKLEY, W. A. June 19, 1950 [June 18, 1949], No. 16251/49. Class 38 (iv). A discharge lamp L is supplied from the secondary SW of a leaky transformer having that end of its primary PW connected to the phase supply terminal P also connected with the secondary at or near one end thereof, thereby providing a high open circuit starting voltage and adequate ballasting with a high power during running. A plurality of lamps, each with its own transformer, may be supplied from a common dimming resistance R by either connecting the primaries of the transformers in parallel, as shown, or in series, the connection between the primary and secondary windings in the latter arrangement, being nearer the phase supply lead. The transformer is preferably of the shell type adjustment of the leakage reactance being effected by varying the relative disposition of the primary and secondary windings spaced along the central limb. The transformer secondary may be tapped to provide filament heating or a starting switch may be used.
Patent GB-497072-A (GB)
Title: Improvements in the manufacture of cellulosic staple fibres
IPC: D02G1/00
Filed: 1937-06-11
Abstract: <PICT:0497072/IV/1> <PICT:0497072/IV/2> Curly fibres similar to wool are obtained by extruding a cellulosic spinning solution to form continuous filaments, uniting these to a thick band or bundle and cutting them to staple fibres before they have been converted to cellulose hydrate, separating the still unconverted staple fibres by means of drums rotating on parallel axes, each drum having a series of annular fins engaging in the spaces between the fins of another drum, and conveying the loose fibre fleece without tension through a conversion bath.  The fibres may be subjected before or during the conversion to cellulose hydrate to an additional treatment for imparting curliness.  The conversion bath may be an acid bath, or a bath which by reason of its high temperature decomposes the substance of the fibres to cellulose hydrate.  The process is applicable to viscose or cuprammonia fibres.  As shown in Figs. 1 and 2, the device for opening up the bundles of fibres comprises a pair of drums d with peripheral fins e arranged so that the fins of one drum engage between those of the other.  The drums rotate in opposite directions at the same or different speeds.  Beneath each of the drums d is mounted a similar drum g for doffing fibres that adhere to the upper drums.  The outer ends of the fins may be smooth, roughened, or provided with slight indentations.  In operation, the cut fibres, e.g. of cellulose xanthate, fall from the cutting machine on to the upper rollers so as to lie approximately parallel to the fins.  As they pass between the latter they are separated from each other.  The loose fleece obtained falls into a conversion bath from which it is withdrawn continuously upon an endless band and further treated, e.g. by showers of various treatment liquids.  Specifications 451,860, 462,184, and 485,106 are referred to.

Filed: 1972-04-12
Abstract: 1332270 Oscillator and switching circuits NITTAN CO Ltd 12 April 1972 [15 April 1971] 16822/72 Heading H3T [Also in Division G4] In a fire alarm system comprising a plurality of fire sensors 25 connected across a pair of conductors 30, 40 each sensor 25 turning on a normally-open switching device (such as thyristor 26) which switching device is only turned off by reducing the voltage between conductors 30, 40 and a central unit 1 for supplying an operation voltage to said sensors 25 and including first means for responding to the closure of any of said normally open switching devices 26 to produce an output voltage, second means for accumulating said output voltage and third means for producing an alarm in response to a predetermined amount of said accumulation. As described, sensors 25 may be responsive to smoke or temperature and are normally energized by transistor 19 and the Zener diode 24 acting as a voltage regulator. In the event of fire, one of sensors 25 turns on the respective thyristor 26, closing the emitter circuit of transistor 19 so that transistors 18 and 19 operate as a multivibrator because of their cross-coupling via capacitors 16, 17. The second half-cycle from the multivibrator turns off thyristor 26. If thyristor 26 is re-triggered by the continual presence of fire conditions, a train of pulses appears across resistor 15 which train is integrated by a circuit 7 and, when the integrated output is sufficient, transistors 33 and 37 are turned on, operating an audible alarm 42 and a relay 41. Transistors 33 and 37 are maintained conductive by feedback via diode 39. The invention prevents false alarms due to spurious triggering of thyristors 26 by short-duration pulses.
