Abstract: 657,503. Knitting-machines. STIBBE & CO., Ltd., G., STIBBE, E. V., and WEST, B. H. Aug. 5, 1948, No. 20702. [Class 74 (ii)] Yarn on its way to the needles of a knitting machine can be drawn from its supply at a rate which varies in accordance with variations in yarn tension, by a mechanism which includes a rockable hub 28 carrying wraplocating guides 32, 33, through which the yarn Y travels as it passes on to and off a single positively driven tapered (e.g. frustoconical) take-off roller 20, around the entire periphery of which it is wrapped, and a further guide 34 through which it passes on its way to the feed eye 5. Variation in yarn tension causes the hub to rock, so altering the position of the wrap lengthwise of the roller and hence the rate of take-off. The hub may have an adjustable counterweight 31 and (according to the Provisional Specification) may comprise a container divided into intercommunicating compartments containing mercury. On leaving the package, the yarn first passes through pairs of slotted tensioning discs 11. The roller may be of rubber or the like, or of wood, metal, or a plastic material coated with rubber or with other friction material. According to the Provisional Specification, the hub may bear a further guide, engaging the run of the yarn between the supply and the wrap-locating guides. A dropper guide 35 is released by yarn failure or breakage and closes an electrical circuit to energize an electromagnet which operates a belt striking gear or equivalent stopping means.

Title: Improvements in and relating to temperature measuring devices
IPC: G01K7/24
Filed: 1955-07-22
Abstract: 807,232. Electrical indicating systems. ANDERSON, J. C. Oct. 17, 1956 [July 22, 1955], No. 21208/55. Class 40 (1). In a temperature measuring device, a thermistor 1 (Fig. 1), constitutes the whole, or part, of the bias resistance of a transistor 6, changes in the resistance value of thermistor 1 producing corresponding changes in the collector current of the transistor, the value of which current is measured by a galvonometer-type meter 7, calibrated to give direct temperature readings. The thermistor 1 is normally in circuit whereas the resistor 12 is not. To adjust the zero reading of the meter, the thermistor 1 is replaced by resistor 12, adjusted to have a resistance value equal to that of the thermistor 1 at a prearranged temperature, and the value of resistance 10 is adjusted to give the desired zero reading. The sensitivity is dependent upon the value of resistance 2. In a modified arrangement (Fig. 2) two transistors 13, 14 are used, only the former being controlled by thermistor 1, and the meter is connected between the two collectors. Variations in the characteristics of the transistor 13 with variations in operating temperature are thus compensated by similar variations in those of transistor 14. The meter is zeroed by switching resistor 21 into circuit in place of the parallel combination of thermistor 1 and resistor 18 and then adjusting variable resistance 25. The transistors are preferably housed in a thermal sink consisting of a metal casing of large thermal capacity.

Abstract: 383,639. Rectifier systems. ALLGEMEINE ELEKTRICIT€TS-GES., 2, Friedrich Karl-Ufer, Berlin. July 30, 1931, No. 21797. Convention date, July 30, 1930. [Class 38 (ii).] In a mercury arc rectifier system comprising a number of rectifiers in parallel there is provided means operating in response to load conditions whereby when the total current falls to a predetermined extent, the exciter circuit of one of the rectifiers is interrupted and the load current is momentarily reduced or interrupted to stop the operation of that rectifier. In one form, the exciter circuit of the rectifier 1 is opened at contacts b when coil Z is energized by closure of a minimum current relay Mi. Simultaneously, contacts a are bridged thus closing the circuit of opening coil A of main switch B, whereupon rectifier 1 is extinguished. The cessation of current causes coil Z to be again de-energized by opening of switch Be whereupon opening coil A of main switch B is de-energized and the switch closes under the action of the closing coil E. In an alternative form shown in connection with the rectifier 2, a switch R is used to open the exciter circuit and simultaneously to close the circuit of the opening coil A of the switch B. A resistance W may be connected across the contacts of the latter in order to avoid release of the feeder switches Str while reducing load current to a sufficient extent to cause extinction of the rectifier the exciter circuit of which has been broken. As alternatives to breaking or reducing load current at the switch B, a switch O on the A.C. side, or the feeder switches Str on the D.C. side may be caused to open when the exciter circuit is broken by arranging connections as indicated by broken lines.
