Filed: 1931-12-03
Abstract: 374,781. Delivering yarn to knitting and warping machines &c. SAEMUNDSEN, C., 3, Amaliegade, Copenhagen. Dec. 3, 1931, No. 33579. Convention date, Dec. 3, 1930. [Classes 120 (ii) and 120 (iii).] In supplying yarn to working-up machines, a loose yarn body consisting of substantially parallel windings is placed on an elastically expansible support from which the yarn is taken off, during-the delivery to the machine, mainly in the direction of the axis of the support. A cylindrical projection b on a baseboard a positions the separated halves c, d of the trunk of a yarn support and a coil spring g, on a guide f for a peg e on the opposite half of the support, thrusts them outwardly into contact with a coil of yarn &c. which is slipped over the trunk when its members have been drawn together against the action of the spring by a fork n. A cap j having a cylindrical projection engaging between the halves c, d of the trunk prevents the coil from slipping off the trunk as the yarn is unwound. Leaf springs may replace the coil spring. The Specification as open to inspection under Sect. 91 (3) (a) states that the trunk may comprise more than two sections, or be formed of a resilient split tube. In another form, the support consists of a hollow body 1, 2, Fig. 5 (Cancelled), adapted to be inflated by air or water to engage the coil. Fabric may be applied to the outside of the body, to increase the friction between it and the yarn. The body may be made of thin elastic material connecting rigid longitudinal bars which ensure the collapse of the body when the inflating medium is withdrawn. The cap may be omitted and the trunk collapse on to a rigid core. An inflated core may replace the coil spring g. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,273,051. Semi-conductor oscillators. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 4 July, 1969 [19 July, 1968; 18 Sept., 1968], No. 33837/69. Heading H3T. [Also in Division H1] A hybrid semi-conductor device is made in the form of an oscillator. Fig. 3 shows an oscillator made of a gallium arsenide body 11 provided with two ohmic contacts 12, 13, that on the lower surface covering the whole face and that on the upper surface being of limited extent. The upper contact 12 is connected to a spiral metal track 15 acting as an inductor and with its underlying oxide or ferrite insulation 14 and the semi-conductor body as a capacitor. The two terminals of the device are the lower contact 13 and the remote end 16 of the metal track. The resistivity and intercontact spacing of the device are chosen to obtain negative resistance operation at high fields without domain formation. In variants the oxide or ferrite insulation is omitted and the inductive track is made to form a Schottky barrier or alloy pu junction with the semi-conductor. The voltage variable capacitance thus formed means that the resonant frequency may be changed by altering the applied DC bias.

Title: Improvement in railway signalling track circuits
IPC: B61L1/18
Filed: 1956-11-07
Abstract: 812,465. Railway signalling systems. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT. Nov. 7, 1956 [Dec. 21, 1955]. No. 34004/56. Class 105. In a track signalling system operating by periodic currents and having integrating means controlling the signalling device, e.g. the track relay, in order to eliminate the possibility of the traction currents resulting from unbalanced return traction power currents in the rails from adversely affecting the operation of the signalling device as by preventing the track relay from dropping away when the rails are shunted, the integrating means is fed from a capacity which is coupled to the output of the track circuit so as to be charged and discharged at the output frequency of the track circuit and is so arranged that its peak voltage decreases as the said output frequency increases so that the controlling voltage at the traction power' frequency is insufficient to hold the relay operated. As shown, a capacity 1 is charged from a D.C. source 2 through a regulating resistance 3 and discharged through the primary winding 4 of a transformer 4, 14 on closure of a switch 5A, which may be electromagnetic or electronic such as a thyratron, under the control of the frequency currents in the windings 13 coupled to the inductive impedance bonds 12 between the insulated track sections 7, 8 and 9, 10, the output in the transformer secondary winding 14 being fed through a rectifier 15 to the track relay 16, the D.C. impulses being integrated by a capacity 17 to apply a steady voltage to the track relay 16 which voltage is sufficient at the signalling frequency to hold the relay but is insufficient at the traction power frequency. In order to avoid too frequently dropping away of the track relay which might be caused by small unbalanced currents which are not dangerous, the switch 5A is arranged to respond only to traction power frequency currents if the unbalance of these currents exceeds a predetermined minimum value.
