Title: Improvements in and relating to apparatus for winding continuous web material
IPC: B29C53/32
Filed: 1950-01-03
Abstract: 673,169. Winding webs. CELLOPHANE SOC. ANON. Jan. 3, 1950 [Jan. 12, 1949], No. 157/50. Class 100 (i). [Also in Group XXIV] Apparatus for winding continuous web material such as films (e.g. of regenerated cellulose), paper or woven fabric, comprises a winding spindle, a differential gear one pinion of which is connected to the spindle, the casing of which is adapted to be driven at constant speed and the other pinion of which is connected to a pump, a closed circuit through which the pump may impel a fluid medium, a throttle valve in the circuit, an element responsive to changes in tension of material ahead of the winding spindle, and means adapted to transmit the response of this element to effect a variation in the degree of opening of the throttle valve. By this means, web material can be wound under constant tension or in accordance with a pre-set variation of tension. As shown, a film 1, delivered at constant speed, is wound in a roll 2 on a spindle 3 driven by one bevel pinion 11 of a differential gear 12 the cage of which is driven at constant speed through a drive 14. The other bevel pinion 11A of the gear drives a gear pump 16 which circulates a liquid (e.g. mineral oil) in a closed circuit 17 past a throttle valve'18 controlled by a pneumatic regulator 10.' Film 1 passes around a tension-detecting roller 4 mounted on a pivoted, spring-loaded stirrup 5 connected to regulator 10. Decrease of speed of spindle 3 as the roll builds up is permitted by the differential gear 12, gear 11A and pump 16 being driven correspondingly faster. Constant winding tension is ensured by roller 4 which acts as follows : movement of roller 4 due to increase of tension causes regulator 10 to open throttle 18, thus lowering the braking effect of circuit 17 and hence lowering the torque transmitted to spindle 3 with a resultant decrease of tension of film 1; similarly any decrease of tension results in a compensating increase. Winding according to a pre-set variation of tension may be effected by making the position of stirrup 5 subject to an overall automatic variation, e.g. under the control of a slowly rotating cam, to vary the tension in accordance with the amount of material already wound.

Title: Improvements relating to electric control apparatus

Abstract: 752,340. Magnetic amplifiers. WESTING- HOUSE BRAKE & SIGNAL CO., Ltd., and KING, K. G. Dec. 3, 1954 [Jan. 6, 1954], No. 375/54. Class 40 (4). In a magnetic discriminator in which a difference flux obtained by balancing a D.C. control winding flux against a permanent magnet reference standard varies the impedance of a detector winding, the control winding has, either alone or in combination with its supply circuit, a positive resistance-temperature coefficient such that variations in the flux of the permanent magnet due to temperature changes are accompanied by a corresponding change of control winding current, with the result that discriminator balance is substantially independent of temperature variations. This arrangement overcomes the inherent negative flux-temperature characteristic of the magnet. Since the copper wire forming the control winding has a positive temperature coefficient in excess of that required, a resistor of negligible temperature coefficient is included in series or in parallel. The resistor may form part of the control winding or may be incorporated in the external circuit. In the latter case, a portion of the resistor may be variable so as to provide a limited range of adjustment.
