Title: Improvements in or relating to apparatus for controlling the speed of a d.c. electric motor
IPC: H02P7/06
Filed: 1930-06-05
Abstract: 356,250. Automatic electromechanical regulators. REYROLLE & CO., Ltd., A., Hebburn-on-Tyne, and LINSTOW, F. N., Sunniside, Midhurst Road, Benton, North. umberland. June 5, 1930, No. 17362. [Class 38 (iv).] A motor A is maintained at constant speed by varying its field A<1> according to the supply voltage and according to speed variations. The motor is used to drive a master frequency generator B, the output of which may control the frequency supplied from a generating station. The field A<1> of the motor is controlled according to the voltage of the supply C by a contact-making voltmeter E controlling, through a polarized relay G, clutch coils J1, J2, which cause the operating member of a field rheostat M and a follower device F to be driven in the appropriate direction by a constantly running auxiliary motor K. When either coil J1 or J2 is energized, a contact J3 is closed to shortcircuit part of a resistance K3 in circuit with the auxiliary motor K. Fine regulation is obtained by a synchronous motor N2, supplied from the generator B, and a master clock N1 acting differentially upon a contact O which controls, through a polarized relay P, clutch coils Q1, Q2. These coils cause cylinders R, R1, one of bare metal and the other of insulating material, to be rotated so as to wind a resistance wire from one to the other.

Abstract: 671,410. Automatic power; power factor control. STEVENS, A. H. (Ohio Crankshaft Co.). July 1, 1949, No. 17453/49. Class 38 (iv). Power regulation..-In an induction furnace, fed from a substantially constant voltage source, e.g. motor-generator, a capacitor is connected in series with the supply to maintain a substantially constant power demand as the impedance of the furnace varies during the heating cycle, Figs. 1 to 7 (not shown). Mathematical formula and graphical construction, Fig. 6 (not shown), are given for determining the critical value of capacity required. Power factor control, Fig. 9.-In such a system the power factor may be controlled at about unity by slightly overcompensating for the lagging load with a fixed parallel capacitor H and offsetting the leading component by a variable (saturable) reactor 20. Since the voltage of a generator rises or falls with leading or lagging current an automatic-voltage-regulator type of device, Fig. 10 (not shown), may be used to control D.C. current through the saturating winding 22 of the reactor. Alternatively the quadrature voltage across a capacitor 30 in the supply line may be differentially added to that from a centre-tapped transformer 36 feeding rectifiers 42, 43 to supply differential saturating windings 50, 51 on a further variable reactor 34 in the rectifier supply circuit for the power-factor-controlling reactor 20.

Patent GB-1081536-A (GB)
Title: Baling twine
IPC: B65D63/10
Filed: 1965-04-28
Abstract: Baling twine is given bulk and strength by combining at least one bulking strand of paper with a plurality of high strength fibres of synthetic plastics material, characterised in that said paper strand, or each of them, is creped, crinkled, embossed or otherwise crimped to render it stretchable.  The paper strand may form an inner core on which the high strength fibres are laid and there may be an outer layer on said high strength fibres of at least one single strand open-wound helix. The outer layer may comprise a first helix overlaid by a second helix of opposite hand.  The stretchability of the paper is preferably made equal to that of the high strength fibres and the components may be united by an adhesive coating applied as the twine is laid-up.  The paper strand may be twisted and overlaid by a layer of high strength fibres having an angle of twist substantially of the same lay and direction as the paper strand.  The high strength components of twine may be synthetic or artificial, smooth-surface fibres of polyamides, polyesters, polyolefins, polyvinyl alcohols, or other polyvinyl compounds, copolymers of the foregoing, regenerated cellulose and other synthetic plastics, metal, glass, or other high strength fibres, either singly or in selective combinations of contrasting colours.  The paper strands may be coloured or marked and may be selected so as to produce a distinctive appearance of the twine which may be indicative of type of origin of ownership.  The core may comprise one or more straight laid, high strength strands sandwiched between two strips of creped paper, the outer binding being relied upon to squeeze the core into a required circular cross-sectional shape.  This may be achieved by feeding a plurality of spaced apart, primary load bearing fibres or bundles thereof, between a pair of feed rolls with a layer of creped paper below the fibres and another above them.  The emerging "sandwich" is then slit longitudinally between neighbouring fibres (or bundles) by means of high pressure slitting rolls which crush the sheets of crepe paper against each other so as to slit them and cause the slit edges to adhere together to some extent; so enabling the paper covered strands to proceed to a work station at which the outer binding fibres are applied.
