Title: Improvements in controlling means for controlling a series of electric motors
IPC: H02P5/48
Filed: 1919-05-12
Abstract: 148,655. Warburton, F. G. May 12, 1919. Systems depending on the use of two or more motors. - In control mechanism of the type described in Specification 22897/14 for motors driving paper - making machines &c., the control is effected by the linear displacement of a member caused by the variation of the speed ratios between the master-control shaft and the individual motors. In the form shown in Figs. 1 and 2, the mastercontrol shaft a runs along the length of the papermaking machine and is provided with a feathered worm b for each motor to be controlled. Each motor c drives a shaft d through change-speed gear such as cone pulleys, or friction disks, and this shaft carries the worm-wheel h engaging the appropriate worm b. As long as the master shaft a and the motor c run at the designed speed ratio, the worm gearing works without any axial movement of the worm, but if this ratio is disturbed the worm moves axially and moves the rack j meshing with a pinion k which rotates the motor brushes to restore the speed ratio. The axial movement of the worm may actuate a shunt regu-. lator, series diverter, or rotor resistance switch. In a modification, the motor c drives one shaft of a differential gear, while the casing is driven from the control shaft a. When the speed ratio varies, a pinion on the end of the differential shaft rotates the motor brushes. In another modification the differential shaft winds up a rope to vary the positions of the plates in a liquid resistance.

Compound sheet materials; fabrics composed of fibrous materials agglutinated by adhesives. - A method of forming sheets of textile material such as cotton fibre in the form of loose unwoven sheets of of flimsy woven material for use in the manufacture of gear wheels comprises treating the material with oil and then compressing it under heat. Layers of fibres from a picker are treated with oil, placed one above the other, and compressed by passage between heated rollers. Blanks are cut from the compressed sheet, assembled and compressed between end plates to form the gear wheel. The apparatus includes a breaker and picker 6, Fig. 1, in which a bale of cotton or cotton waste is separated and spread out into a thin sheet of fibres 7. The sheet passes between rollers 8, 9, and is sprayed with oil, preferably light machine oil, by rotating brush mechanism 12, 13. The amount of oil used is such that little or no oil is pressed out, in the final consolidation. The layer is then wound on a spindle 16. A number of these rolls 11, Fig. 2, are placed in a framework, and the layers of fibres drawn off by means of an endless belt 19. The resulting sheet of superposed layers 21 is passed between heated pressure rollers 22. The pressure is of the order of 1,000 1bs, per square inch, and the temperature about 325‹ F. A sheet which is sufficiently stiff to be handled and to be cut into blanks is thus produced. It may be cut into suitable lengths by a tool 23. Discs 26, Fig. 5, of suitable size are cut from the sheet and stacked between metal end plates 27, the whole being consolidated in a hydraulic press and fastened in compressed state by means of rivets 28.

Title: Improvements in or relating to power supply regulating equipment
Inventor: JONES ERIC LINDSAY
IPC: G05F1/52
Filed: 1958-04-18
Abstract: 817,318. Automatic voltage regulation; rectifying. KOLSTER-BRANDES Ltd. April 18, 1958, No. 12348/58. Classes 38 (2) and 38 (4). In an electrical rectifying equipment, a regulator stabilizing the load voltage is controlled by a comparator circuit responding to the differences between the load voltage and a reference voltage. The voltage across the regulator is maintained approximately constant, by controlling the rectifying means with a signal derived from the output voltage. In Figs. 1 and 2, a bridge-connected rectifier 8 is connected in series with a full-wave rectifier 11, and the smoothed output voltage appears across terminals a, g. A series regulating triode 19 stabilizes the load voltage 20, 21. The voltage from the full-wave rectifier 11 is approximately equal to the working voltage from anode to cathode of the series regulating triode 19, and the voltage across the bridge rectifier 8 is controlled so as to be approximately equal to the load voltage by varying the conducting period of thyratrons 4, 5 by applying to the centre tap of transformer 14, supplying the control grids, a D.C. bias voltage through line 13, of value equal to the load voltage less the voltage drop across a stabilizing tube 30, the load voltage being applied to a point B through a line d. A reference voltage at a tapping H, on a potentiometer G, I, is supplied from a rectifying valve 62, through a smoothing circuit and a voltage stabilizer tube 68. The reference and output voltages are fed to the grids of the double triode 37, the anodes of which are direct-coupled to the grids of a double triode 38 arranged to compare the two voltages. The amplified difference voltage being fed by line 45 to the grid of a triode 46, arranged as a cathode follower with a resistor 47 and a triode 48 in the cathode circuit. The grid of the regulating valve 19 is connected by lead 50 to point J which controls the bias voltage so as to maintain the output voltage constant. The voltage across resistor 51, connected to line d by resistor 80, and line a by resistor 52 biases the grid of valve 48 to compensate for fluctuations in the voltage applied to lead a. The resultant additional bias applied to the regulating valve is equal to the anode-to-cathode voltage fluctuation divided by the amplification of the valve. A current is maintained through the circuit when the load current is zero by a pentode 59, connected from the output terminal 20 to an auxiliary supply h derived from one side of the secondary of transformer 3, by a rectifier 55, and stabilized by a valve 58. If the grid-controlled rectifiers 4 and 5 are biased to cut-off, a diode 73 maintains a D.C. connection for the output of the full-wave rectifier 11. A thermal cut-out 74, 75 breaks the circuit on sustained overload.
