Abstract: 510,730. Converting; automatic control systems. STANDARD TELEPHONES & CABLES, Ltd. Feb. 11, 1938, No. 4404. Convention date, Feb. 20, 1937. [Classes 38 (ii) and 38 (iv)] In an arrangement in which a D.C. circuit B, B, Fig. 2 is fed from an A.C. circuit 1, 2, 3 through a transformer T and rectifiers R, chokes LC1, LC2, LC3 being connected in the primary circuit and variably saturated by the load current to give regulation in dependence on load, additional star-connected inductances Lal, La2, La3 are connected in parallel with the primary of the transformer T and variably saturated under the control of a regulator Re to maintain constant voltage at the load despite variations at the supply. The saturating windings Ls are connected in series with the regulator resistance across the D.C. circuit, the resistance varying inversely with the circuit voltage. In a modification the regulator resistance is in parallel with the windings LS, and the current is obtained from the A.C. supply through a rectifier having a drooping voltage-current characteristic. In a further modification shown in Fig. 4 two sets Ls<1>, Ls" of saturating windings are used, one being supplied direct from the D.C. circuit and the other being supplied through a regulator Re. The windings act in opposition, and the regulator Re is such that its resistance varies in dependence on the circuit voltage. To increase the sensitivety of the arrangements rectifier elements S, which offer a resistance which decreases with the current in the conducting direction, may be connected in the relay and saturating winding circuits.

Title: Textile machines
IPC: B27M3/00
Filed: 1972-01-31
Abstract: 1391273 Stuffer box crimper PLATT INTERNATIONAL Ltd 23 Jan 1973 [31 Jan 1972] 4465/72 Heading D1F [Also in Division G3] A stuffer-box-crimped yarn is wound into a package by means driven by a D.C. electric motor, and the yarn plug level in the box is maintained between limits by controlling the motor speed in accordance with the rate of yarn feed to the box, the plug level and the package diameter. As shown, Fig. 1, crimped yarn 30 is withdrawn from plug 32 in stuffer box 8 and wound on package 34 rotated by D.C. motor 28. Crimping wheels 6, rotated by D.C. motor 12, feed yarn into the box. Tacho-generator 39 driven by motor 12 produces a voltage dependent upon the yarn feed rate. Ultrasonic or photoelectric emitter-detector units 18-14 and 20-16 detect plug level movement. Arm 26 pivots with package growth to adjust diameter sensor 41. The voltage produced by tacho-generator 39 is fed as a speed reference voltage to amplifier 62, Fig. 2, to control thyristor 63 which controls the armature voltage and speed of motor 28. Diameter sensor 41 controls variable resistor 69 to reduce the reference voltage in direct proportion to the increase in package diameter. The voltage produced by tacho-generator 37, driven by motor 28, is fed to amplifier 62 to maintain motor 28 rotating at a speed resistant with the reference voltage. When the level of plug 32 falls so that detector 16 receives pulses from emitter 20, switch 72 is opened to introduce resistor 71 into the circuit to decrease the reference voltage to produce a five per cent decrease in the speed of reactor 28. When the plug level rises so that detector 14 is prevented from receiving pulses, switch 74 is closed to shortcircuit resistor 75 to produce a five per cent increase in motor speed.

Title: Improvements in the treatment of soapstock
Inventor: HURT NORMAN ALBERT
IPC: C11D13/30
Filed: 1954-02-16
Abstract: A process for bleaching soapstock obtained in the alkali refining of animal and vegetable oils comprises treating the soapstock with a hypochlorite in the presence of a chlorite, both preferably present as sodium salts.  The chlorite may be added to the soapstock before, with or after the hypochlorite, but preferably solutions of chlorite and hypochlorite are mixed immediately before addition to the soapstock.  The chlorite may be used in quantities from 0.1-10 per cent, preferably 0.5 per cent, and the hypochlorite, as an aqueous solution containing about 14 per cent available chlorine, in quantities between 0.1-20 per cent (equivalent to 0.02-3 per cent alkali metal hypochlorite); the temperature of the soapstock should be 40-100 DEG C., preferably 60 DEG C., and the time of contact between 0.5 and 30 minutes, preferably 15 minutes.  If desired, the chlorite and/or hypochlorite may be formed in situ by passing chlorine and/or chlorine dioxide into an alkaline solution of the soapstock.

Abstract: 305,940. British Thomson-Houston Co., Ltd., (Assignees of Kellogg, E. W.). Feb. 11, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Thermionic amplifiers.-Hum is eliminated from a thermionic amplifier supplied with current from a fluctuating source, by applying the ripple voltage in opposite phase to the grid and the plate, and in such amplitude as to balance out in its effect on the plate current. Filament voltage for the valve 4 is taken from adjacent tappings 12 on the resistance 2 connected across the supply source 1. Plate voltage is taken from a tapping 8 on the positive side of the filament taps, and grid bias is taken from a tap 21 through a high resistance 20. Ripple voltage is applied to the grid from a tapping 23 through a large condenser 22, and the tapping 23 is so chosen that the ripple voltage thus applied to the grid just neutralizes the ripple voltage applied by the tap 8 to the plate. Similar connections are made for the preceding valve 3. The ratio of the distances of the points 8, 23 from the filament tap 12 should be equal to the amplification factor of the valve.

[Class 38(v)] A glow discharge starting switch, Fig. 1, for electric discharge devices comprises a glass envelope 1 containing low pressure neon, a first bimetallic strip 6 having a contact 7 at one end, a co-operating fixed contact 8 on lead 3 and a second bimetallic strip 9 more sensitive to temperature changes than the first strip 6, the strips deforming in response to heat from a glow discharge between them so that a contact 10 carried by the second strip 9 engages a contact 11 on the first strip 6 to move its contact 7 away from the fixed contact 8, the subsequent cessation of the glow discharge causing the contact 10 to disengage from the contact 11 prior to the re-engagement of the contacts 7 and 8. The strips 6 and 9 are constructed with the metal having the greater coefficient of thermal expansion on the outer and inner sides thereof respectively, and are similar as to form, and the metals employed except that the strip 9 is thinner than the strip 6. The strips 6 and 9 are coated with a high electron emission film except that no coating is applied to the contact 7 or to the end portion of the strip 6 adjacent to the contact and the lead 3 is uncoated so that a glow discharge does not readily form in the envelope which would shunt the lamp. Fig. 2 shows the starting switch 1 connected in a branch circuit across the fluorescent lamp 12, the electrodes 13 of which are connected to a source of alternating current 14 through the control switch 15 and the ballast 16.
