Title: Improvements in or relating to alternating voltage control circuits
IPC: G05F1/38
Filed: 1962-06-08
Abstract: 936,792. Automatic voltage control. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 8, 1962 [June 12, 1961], No. 22303/62. Class 38 (4). In an automatic alternating voltage control circuit of the type in which a transductor connected in series with a load is controlled over, an amplifier in accordance with the difference between a reference voltage and at least part of the output voltage, the biasing current for the transductor is passed through a resistor, the voltage drop across which, when exceeding the reference voltage, takes over control of the amplifier to limit the biasing current and hence the load current. As shown, a load 5 is supplied over a transductor 6, 6<SP>1</SP>, 8, 8<SP>1</SP> and a fuse 4 with A.C. derived from an inverter 3 connected to a D.C. supply source 1. The voltage across the load is applied to a potentiometer 15 by way of a transformer 9, 11, a rectifier 12 and a smoothing circuit 13, 14, and a tapping on the potentiometer is connected to the base of a transistor 16 which thus compares a voltage proportional to the output voltage with a reference voltage derived from a Zener diode 17 in the emitter circuit of the transistor. The collector of transistor 16 is connected to the control winding 20 of a magnetic amplifier which controls, over an output transformer 30 and a rectifier 31, the current in the biasing windings 8, 8<SP>1</SP> of the transductor whereby the output voltage is maintained constant. The transductor biasing current also passes through a fixed resistor 33 and an adjustable resistor 34, the voltabe across which is also applied to the base of transistor 16, over a diode 35 operating as a gate. The resistor 34 is so adjusted that, on overload, the voltage drop across it becomes larger than the reference voltage across the Zener diode 17 and larger than the voltage derived from the potentiometer 15, whereby the diode 35 is rendered conducting causing a much larger collector current to flow. The bias magnetization of magnetic amplifier 20 is thus reduced and the current through the transductor windings 8, 8<SP>1</SP> is also reduced so that the load current is limited to a safe value.

Title: Method and apparatus for taking up a yarn onto a pirn after  false-twisting
IPC: B65H59/38
Filed: 1972-05-15
Abstract: 1394093 Winding up yarn KANEBO Ltd 15 May 1972 [14 May 1971] 22607/72 Headings DID and D1F [Also in Division H1] False twisted yarn is fed by a delivery roller to a take-up roller which winds the yarn on to a cop, and the per cent take-up feed is varied continuously and as a function of time in accordance with a programme represented by a curve in the form of a reference stretch recovery characteristic curve for the wound yarn. The per-cent take-up feed is defined as the difference in surface speed of the rollers expressed as a percentage of the surface speed of the delivery roller. The reference curve is defined as a curve showing the relationship between the per cent stretch recovery of the thermally treated yarn and the location of the yarn in the configuration of a thermally treated yarn. Yarn 1, Fig. 5, is heat treated at 4, false-twisted at 6 and fed by delivery rollers 7 to be wound by take-up roller 8. The speed of roller 8 may be adjusted to vary the per cent take-up feed according to the programme shown in Fig. 4A, which is a straight line approximation of the inverse reference curve shown in Fig. 3A. The approximate curve may consist of less than three straight lines. Alternatively, the delivery roller speed, or the speed of both the delivery and take-up rollers, may be varied. The wind-up of nylon and polyester yarns is exemplified. Roller drive. Roller 8 is driven by an expanding-pulley variable speed gear controlled by a pulse motor receiving electrical pulses from generators associated with each straight line portion of the approximate curve. The pulse motor comprises, Fig. 12, an electromagnet 103 in housing 104, and a disc 106 mounted on shaft 112 and separated from the housing by balls 107.

Abstract: 1,020,404. Automatic exchange systems. SIEMENS & HALSKE A.G. June 3, 1964 [June 7, 1963], No. 22874/64. Heading H4K. In an exchange having first subscribers provided with D.C. impulse transmitters and second subscribers provided with key-senders for code dialling, a transmission bridge which may be taken into use by either type of subscriber comprises an impulsing relay which brings up a delayed action dialling relay during reception of D.C. impulses and brings up an alternative relay which controls a code receiver during reception of code dialling signals. A calling line is connected through finder K to a transmission bridge Ue whereupon relays S and C come-up. Assuming that the caller is of the first type then during the first impulse of each train relay S falls back and brings-up slow-tooperate relay V (relay CA is momentarily energized but falls back when V operates since rectifier Gl1 is then reverse biased). Relays V and C hold for the duration of each train, while S repeats the impulses to a register WU. Similarly if a subscriber of the second type is calling then he also breaks the line loop during signalling so as to release S and bring up CA but in this case the accompanying code signal (two successive signals on one or both line wires) is received in a code receiver WE whereby the corresponding relays A to D comes up followed by CB. The latter, prevents V from operating, holds C and causes CA to remain up. The code signals are translated and may be stored in the register Wu.
