Abstract: 615,376. Stopping and starting machinery. ENGLISH ELECTRIC CO., Ltd., ALLWOOD, G. H., BALL, R. D., and CROSS, J. E. Aug. 6, 1946, No. 23233. [Class 80 (ii)] A rotatable clutch member is arranged to be moved axially to engage the drive between two rotatable members by an electric motor operating through a coaxial screw and nut mechanism, and a spindle extending through the hollow shaft of one clutch member. As shown applied to a mechanical actuator, the member 1 is splined to a driven shaft 2 and is connected by a ball bearing 34 to a spindle 33 which passes through a hollow shaft 14 of the main driving motor 15. The end of the shaft 14 carries rigid therewith the driving clutch member 13. The remote end of the spindle 33 is splined to the bore of the shaft 28 of the motor 24 and is also connected by a ball thread 35 with the end plate 31 of the motor. The'shaft 28 is connected by a spring 36 to the casing 32 of the motor. In operation, the main motor 15 may be brought up to speed, then energization of the motor 24 causes axial movement of the spindle 33 through the screw and nut mechanism to engage the clutch members 1, 13. Deenergization of the motor 24 allows the spring 36 to rotate the shaft 28 in the reverse direction and thus disengage the clutch and force the member 1 against the housing to brake the shaft 2. In modifications, the motor 24 may be reversible and the spring 36 omitted, or the motor 24 may apply the brake and the spring 36 the clutch.

Abstract: 1302574 Inverting GENERAL ELECTRIC CO 14 May 1970 [15 May 1969] 23465/70 Heading H2F In an inverter having a variable input D.C. voltage each commutating capacitor 43a is charged from an auxiliary D.C. source 25 via an impedance 44a and a switching device 45a and is discharged via one winding 30a of a transformer when one main converting element 29a is turned on, the other winding 30a<SP>1</SP> of the transformer being arranged to turn off the complementary main converting element 31a. The circuit is applicable to control of a variable speed induction motor, arranged to have constant torque characteristics, by reducing the applied voltage in proportion to its frequency. The voltage applied to the motor 40 is adjustable by control of the conduction angle of thyristors 16 forming part of a bridge rectifier 14, feeding D.C. to lines 20, 21 of the three-phase inverter. The commutating voltage supply on line 25 is provided by diodes 22 and 15, the latter forming part of the main rectifying bridge. When thyristor 29a is turned on, capacitor 43a, previously charged by turning on transistor 45a, is discharged by winding 30a, which is coupled to winding 30a<SP>1</SP> so as to turn off thyristor 31a. This action also turns off thyristor 29a but it is rapidly retriggered. Tranistor 48a is then turned on so as to charge commutating capacitor 46a via an inductor or resistor 47a. Feedback paths for reactive current are provided via diodes 34a, 36a. Thyristors 29a may be replaced by triacs, diacs or by pairs of transistors. Transistors 45a, 48a may be replaced by thyristors, gate turn-off devices or by silicon controlled switches. Triggering thyristors.-In Fig. 2a (not shown) a variable frequency oscillator operating at six times the required output frequency is fed to a three-stage shift register feeding outputs every 60 degrees to respective gates which pass signals from a high frequency carrier source to the appropriate thyristor 29a and commutating transistors 45a.

Class 72 A method of supervising metal melting processes by determining the amount of oxygen, hydrogen, nitrogen, and other gases in the gases extracted during vacuum melting comprises causing the gases to glow by activation at pressures within the range 0.01 to 5 mm. Hg in a gas discharge vessel by a constant high frequency field and analysing the light emission spectroscopically. As shown, gas from an extraction furnace A passes through a diffusion pump B into an activating vessel C which has a water cooled high frequency coil F. The gas activation in the vessel C may be kept so constant that the absolute intensities of the individual components may be measured by a spectroscopic analysis apparatus H. The lines used for hydrogen analysis are H#, Hγ, and He, for carbon monoxide those around 4510Š and nitrogen those around 7000Š. Instead of keeping the gas pressure constant, the gas may be introduced into C at a pressure above 0.1 mm. Hg and the pressure reduced to below 0.1 mm. Hg and the maximum intensities measured. The gases to be analysed may be taken directly from a high frequency vacuum furnace or from a vacuum casting apparatus.
