Title: Vacuum deposition plants
IPC: C23C14/54
Filed: 1975-10-03
Abstract: 1525945 Determining particle density in a vapour deposition plant using Doppler effect BALZERS PATENT UND BETEILIGUNGS AG 3 Oct 1975 [9 Oct 1974] 40514/75 Heading G1A In an apparatus for determining the particle flow in a vacuum deposition plant V for producing thin films on a substrate Su, the displacement of the absorption wavelength of a laser beam or the attenuation of the beam by reason of the Doppler effect of the velocity of the particles (travelling to the substrate) is measured. A laser beam from a dye laser FL pumped by a nitrogen laser N is directed through the particle streams formed from two sources Q A , Q B , which are vapourized by way of a heater H. The laser beam is received by a detector D 1  and may be redirected via a semi-reflector mirror Sp and mirrors R, back through the parthole along a path at right angles to the first beam path to be received by a further detector D 2 . The description refers to formulae and examples for different orientations of the laser beam with respect to the particle velocity of the substrate. The measurements may also be carried out not only at the position of maximum absorption but also at the "flank" of the absorption line. In another form the transmissivity is measured in one direction at an absorption maximum, then the laser wavelength is varied by ## in such a way that a minimum is obtained in the other direction which would then represent an absorption maximum in the second direction. The particle density is then obtained from a disclosed formula. In a further form a single beam is used that is parallel to the direction of movement of the particle stream in combination with measurement of the wavelength of light required for fluorescence. The general absorption of the beam enables measurement of the density of the particle stream and the measurement of the wavelength necessary to cause excitement as compared with that required to cause excitation in a stationary gas provides a Doppler effect measurement and hence the velocity of the particles.

Title: Device for automatically controlling the speed of a motor vehicle
IPC: B60K31/04
Filed: 1976-10-06
Abstract: 1520609 Automatic control of vehicle speed and acceleration VDO ADOLF SCHINDLING AG 6 Oct 1976 [9 Oct 1975] 41542/76 Headings G3N and G3R A device for automatically controlling the speed of a motor vehicle includes a source for generating a signal representing the speed of the vehicle, a store arrangement providing a signal representing a desired speed of the vehicle and a comparator for comparing these signals and producing a speed error signal for the operation of an actuator for controlling the vehicle speed further includes a switch for making this retroactive system operational and a timing circuit started by operation of the switch and operating to cause a limiting effect applied to the speed error signal to be reduced during the timing period so that the acceleration applied to the vehicle is reduced when switching in the automatic control.  In the arrangement shown a large error signal present when the switch 18 is operated causes the differentiator 9 to reduce the signal to controller 5 to a low level. At the same time switch contact 17 closes to start timing circuit 13 which alters the biasing potential at point 20 thus reducing the effect of the amplifier 9 and allowing a greater signal to be applied to controller 5.

Filed: 1967-09-13
Abstract: 1,201,502. Semi-conductor devices. UNITED AIRCRAFT CORP. 13 Sept., 1967 [19 Sept., 1966], No. 41690/67. Heading H1K. [Also in Division H3] A microwave oscillator employs a semiconductor diode capable of exhibiting the Gunn effect but operated in a different manner. In the Gunn effect oscillator, acknowledged in the Specification as known, a voltage just in excess of a threshold value produces current oscillations of a predetermined frequency (transit time frequency) having an average current value below the current at the onset of oscillation and a current amplitude not substantially exceeding the amplitude at the onset of oscillation (Fig. 3, not shown). In the present oscillator, the voltage applied to the semi-conductor diode body 10, e.g. from a source 12, substantially exceeds the Gunn threshold and the circuitry includes a resonant circuit RC whose natural frequency exceeds the transit time frequency. Under these conditions, provided that the carrier concentration in the semi-conductor is within predetermined limits, oscillations (Fig. 2, not shown) are produced at the tuned circuit frequency and with both a greater amplitude and a greater average value of current than in the simple Gunn oscillator. The carrier concentration in the semi-conductor may be maintained within the required limits by suitably controlling the temperature of the semi-conductor body or its housing 16. The body temperature should be in the range - 78‹ to + 27‹ C. The Specification discloses a technique for providing a GaAs body with tin electrodes in such manner that the completed device will serve as the diode of the above circuit. CdTe is also mentioned as a suitable semi-conductor material.

Title: Apparatus for measuring by measurement of phase shift
IPC: G01M1/22
Filed: 1963-10-31
Abstract: 1,016,720. Measuring rotor unbalance electrically. GENERAL MOTORS CORPORATION. Oct.31, 1963 [Nov. 5, 1962], No. 43027/63. Heading G1N. Apparatus for determining the phase and magnitude of the unbalance of a rotor comprises means including a synchronous reference signal for reversing one half-cycle of the electrical unbalance signal at an adjustable angle to give zero average output, thereby determining the phase of the unbalance, then displacing the reference or unbalance signal by 90 degrees to give an output signal whose average value is indicative of the magnitude of the unbalance. As shown (Fig. 1) a test rotor 10 is driven by a motor 12, the unbalance being measured by a pickup 16. A reference signal 22 having the same frequency as the unbalance signal 64 is obtained by a magnetic or photo-electric pickup 14 and used to control a multivibrator 38, the output frequency being measured by a meter 42 indicating rotor speed. The signal is differentiated and the positive pulses used to stroke the output of a sawtooth generator 50, which, together with an adjustable D.C.bias from 56, is fed to a bi-stable circuit 54 to produce a rectangular pulse train 55 of the same frequency whose mark/space ratio is determined by the variable bias 56. These pulses are differentiated at 60 and the second pulse, whose phase is adjustable by the variable bias 56, triggers a square wave generator 28 whose output 30 is fed to a synchronous rectifier 32, together with the amplified unbalance signal 64. The phase of the square waves 30 is adjusted by the variable bias 56 to coincide with the unbalance signal 64, as shown by a zero reading on a meter 98 averaging the output from rectifier 32, this phase being measured by a meter 58. The unbalance signal is now shifted by 90 degrees by unit 70 and the rectifier output on meter 98 is indicative of the magnitude of the rotor unbalance. The phase and magnitude readings on meters 58, 98 may be stored in memory devices 62, 81 and used subsequently to control an indexing mechanism 18 and a balance correcting mechanism 20. In a modification (Fig. 4, not shown), the additional D. C. bias to be added to the sawtooth signal 52 is produced automatically to give zero averages output from synchronous rectifier 32, and the square wave signal 30 is also fed through a 90 degree phase shifter to a separate sinchronous rectifier to indicate the magnitude of the unbalance on meter 98.
