Abstract: 1,110,889. Transistor switching circuits for solenoids. NATIONAL CASH REGISTER CO. 11 April, 1967 [23 May, 1966], No. 16431/67. Heading H3T. A solenoid, Fig. 2, is rapidly energized by simultaneously making two switching devices 98, 99 connected to two windings 95, 96, the number of turns of 96 being smaller than 99 so that the back e.m.f. initially blocks a unidirectional conductor 100 in the circuit of switch 98. The initial energization may thus be made greater than the holding energization without applying excessive voltage. The windings may be connected to different supplies or may be respectively the whole and part of a single winding (Figs. 3 and 1, not shown). In Fig. 4 the whole winding 12, 13 is connected through a diode 16 to a " hold " transistor circuit 17 and winding 12 to a " boost " circuit 20 comprising two transistors 51, 52 in parallel. A signal at 23 passes through an inverter 86 to make hold transistor 35 ready to conduct and also passes via a control circuit 21 to a transistor 70 to render the boost transistors conductive. A large initial current builds up through winding 12, the back e.m.f. blocking diode 16 until the rate of change of current through the boost circuit decreases sufficiently to allow the diode to conduct current to the hold to be solenoid operated. The control circuit 21 comprises a monostable circuit 88, and AND gate 89 and an inverter 90. The AND gate is opened by the concurrent appearance of the input signal and the output of the monostable circuit so that the control signal for the boost transistors terminates when the monostable circuit reverts or the signal terminates whichever occurs first. The CR circuits 24, 25 ; 39, 47 ; 40, 48 give an additional initial boost to the currents, diode 32 limits the reverse voltage across the whole winding and the diode circuits 53, 54 limit the reverse voltage across the section 12. The collectors of the boost transistors 51, 52 are protected by circuit 57, 58, 59 and 60, 61, 62.

Title: Manufacture of artificial threads and other products from cellulose
IPC: D01F2/06
Filed: 1930-05-28
Abstract: Artificial threads and other products are made from viscoses using the ordinary spinning or coagulating baths, while employing viscoses having viscosities much in excess of the viscosity of viscose normally used for spinning threads, and as compared with glycerine of 1,26 specific gravity, not substantially smaller than 50 per cent of the amount of the cellulose contained in 100 parts of the viscose, preferably not substantially smaller than 75-100 per cent of such amount.  In particular, it is preferred to use viscoses the viscosity of which is not less than \bac<4>-6c<2>/4a\be, preferably not less than \bac<4>-6c<2>/3a\be, where c and a represent respectively the percentages of cellulose and alkali in the viscose, and in the case of viscoses containing 3 per cent or less of cellulose, a viscosity not less than \ba2c/a\be, preferably not less than \ba3c/a\be.  By the use of such viscoses, threads having a high dry and wet tenacity are obtained without the use of plasticizing spinning baths.  For the preparation of viscoses of these high viscosities, there may be employed a parent cellulose of high primary viscosity, a low temperature in the shredding of the alkali cellulose and in its maturing if that takes place, and a low temperature in the sulphidizing step.  Examples are given of the spinning of threads, the manufacture of films, and the coating of fabrics.  In these examples, the viscoses employed contain 3-6 per cent of cellulose and 5-8 per cent of alkali, and have viscosities between 1,2 and 45; and the threads leaving the coagulation baths, after passage through the air are led round a number of rods or rollers placed angularly to one another so as to permit of additional stretching of the threads which are finally wound up on bobbins running in dilute acid; alternatively, rollers running at varying speeds may be used to effect the stretching of the threads.  After washing and before or after drying, the threads may be heated or steamed at high temperatures.  The extensibility of the threads may be improved by treatment with shrinking agents, for example, according to the processes of Specifications 281,352, 312,197, 323,731, and 323,732, [all in Class 2 (ii), Cellulose &c.].  The viscoses may also be used in the manufacture of films, as coatings, dressings, sizings, adhesives and cements, in the manufacture of book cloth, artificial leather, plates and plastic compositions, and as thickening agents for pigments &c.  Specifications 213,931, 264,161, 274,521, 274,690, 281,351, 298,548, and 317,608, [all in Class 2 (ii), Cellulose &c.], also are referred to.
