Title: A device in which, when it is used, an electric arc passes between two electrodes through a gas in the device and the gas leaves the device in a stream
IPC: H05H1/34
Filed: 1970-11-02
Abstract: 1283909 Monitoring a gas stream photoelectrically SIEMENS A G 2 Nov 1970 [3 Nov 1969] 52088/70 Heading G1A [Also in Division H5] In a device for generating a stream 24 of electrically excited gas by means of an electric arc 26 between two electrodes 2 and 4, at least one of the electrodes is provided on its surface remote from the arc with a coating 33, 34 of material which, when the arc burns through the electrode to reach the coating, alters the emission spectrum of the gas stream and hence causes a monitoring device, e. g. a photocell assembly 38-44, to interrupt the current supply to the electrodes. A filter 38 isolates a spectral region or line characteristic of the coating material to produce the control signal. The photo-cell 44, located adjacent a diaphragm 42, may be a gallium arsenide diode, a photo-resistor or a photovoltaic cell, and it may form one arm of a bridge. Within the arc chamber 20, which has an aperture for introduction of the gas stream, the annular copper electrodes 2 and 4 are movable in an axial direction. The coating may be of aluminium, dural (Trade mark), chromium, sodium or a sodium salt. The electrodes may be double-walled, in which case the coating is contained between the walls. The coating may be soldered, welded, shrunk or cast on to the electrode material. Field coils 28, 29, which cause the arc to rotate, contain hollow conductors 30 through which flows cooling liquid. Further cooling liquid flows between the electrodes and the field coils. Power for the electrodes is derived from a 380V. three-phase supply controlled by an adjuster 10. The adjuster output feeds a rectifier 6 whose output is 850A at 700V. The current supply is kept constant by using a transducer 18 to sample this current and compare it in a regulator 17 with its nominal value supplied at 19.

Filed: 1968-11-04
Abstract: 1, 248, 617. Measuring length photo-electrically. REDERI A.B. NORDST JERNAN. Nov.4, 1968 [Nov. 3, 1967], No.52212/68. Heading G1A. The length of a moving object 1 is measured by following one end 8 of the object with a photoelectric detector unit 4 until the other end 9 of the object is sensed by a fixed detector unit 5 and registering the position of the detector unit at that time. The detector unit 4, which includes field defining optics, a contrast enhancing filter, a mechanical chopper or an electrically pneumatically or hydraulically varied diffraction filter cooperating with a band-pass filter and a detector 12, gives an A. C. output proportional in amplitude to the amount of object 1 in its field of view. Whenever the output exceeds a pre-set level, threshold circuit 13 energizes an electric or hydraulic step motor 15, which rotates the detector unit 4 about axis 6 to follow the end 8 of the object. The angular steps may be made to correspond to equal linear steps in plane 2. The output from detector unit 5 is fed to a threshold circuit 21 to signal the passage of end 9 of object 1. Switch 14 opens in response to the signal from circuit 21 to stop tracking of the edge 8 by detector unit 4, the position of which is then determined. Detector unit 5 may also set the threshold level of circuit 13 in dependence upon the brightness of the object. The radiation used may be that emitted by the body, if hot, or reflected by the body from a modulated source 19 which may be located where it can illuminate both ends of the object. Parallax errors are compensated by a further detector unit 16 directed at a point in plane 2 at which detector unit 4 should pick up edge 8. If the object departs from plane 2, detector units 4 and 16 pick up the edge 8 at different instants and the time lag is used, together with the speed of the strip measured by the time taken to pass from detector unit 5 to unit 16, or otherwise, to compensate the measurement automatically.

Abstract: 1,150,799. Slack adjuster. SVENSKA BROMSREGULATOR A.B. 23 Nov., 1967, No. 53380/67. Heading F2E. A pneumatically operated piston 2 and a brake actuating threaded spindle 3 are connected by automatic slack adjusting nuts 4, 5 on the spindle 3 and internal surfaces 18, 19 attached to the piston, the nut 5 slidably carrying a collar 24 having a projection 25 extending through a longitudinal slot 11 in the piston 2; engagement of the projection 25 with a stop 12 fixed to the stationary casing 1, 10, during brake application causes a shoulder 32 of the collar 24 to compress a spring 27 against a thrust bearing 28 in the nut 5 to prevent further axial movement of the nut which then rotates to take up the slack, and engagement of the projection 25 with a part 7 fixed to the casing 1 upon brake release causing engagement of teeth a-a on the collar 24 and the nut 5 respectively to prevent further rotation of the nut 5. Further axial movement of the nut 5 relatively to the spindle 3, therefore, is prevented, and the remaining movement of the piston 2 to the right under the action of a brake release spring 8 separates the other nut 4 and the surface 18. A spring 23 acting on a thrust bearing 22 causes the nut 4 to rotate and to progress along the spindle until it again engages the surface 18. The piston and spindle combination is thus lengthened to take up slack.
