Filed: 1960-05-17
Abstract: 980,807. Operating railway points. JOSEPH LUCAS (INDUSTRIES) Ltd. May 1, 1961 [May 17, 1960], No. 17342/60. Heading B7N. A control apparatus for a railway point comprises a pair of " AND " gates p, r, one or other of the gates p, r being caused to produce an output which operates one or other of means u, v, respectively, for moving the point to one of its two alternative positions. Each control apparatus also comprises four " OR " gates g, h, i, n, three switches j, k, m connected to a source of supply providing an input signal in the form of a series of pulses, signal dividers s, t, and three pairs of terminals a, b; c, d; e, f interconnected as shown. The Figure shows two interconnected control apparatuses, the second with suffixed reference numerals, adapted for the control of the two points on a track which divides into two, one of the divided tracks then further dividing into another pair of tracks. If it is desired to set the points so that a train can pass from the original track to the central of the three divided tracks then switches j, m<SP>1</SP> are closed. As a result of closing switch j, signals flow from the " OR " gate g to the " AND " gates p, r, through signal dividers s, t, and also to " OR " gate g<SP>1</SP>, and thus to " AND " gates p<SP>1</SP>, r<SP>1</SP>. As a result of closing switch m<SP>1</SP>, signals are fed to " AND " gate r<SP>1</SP> through " OR " gate i<SP>1</SP>, and to " AND " gate p through " OR " gates n<SP>1</SP>, h. Thus both the input terminals of " AND " gates p, r<SP>1</SP>, receive signals and output signals will be fed to means u, v<SP>1</SP> to control the points. The supply to the " AND " and " OR " gates may be fed through relays associated with sections of the track, so that if a vehicle is on a particular section of the track no power is fed to the associated gates. Where it is required that two points should be operated in synchronism, one " AND " gate may operate both points. Specification 933,228 is referred to.

Filed: 1945-07-06
Abstract: 595,906. Testing balance of rotating masses. SELF-PRIMING PUMP & ENGINEERING CO., Ltd., and WATSON, F. J. July 6, 1945, No. 17346. [Class 106 (ii)] [Also in Group XXXVIII] Apparatus for testing unbalance in a rotating mass comprises an electrical pick-up in which current is generated in response to mechanical oscillations of the mass, a cathode-ray oscillograph to which the pick-up is coupled, a sinewave generator in the form of an alternator driven with the mass and electrically coupled to the oscillograph, means associated with the alternator for varying the phase difference of its current and the current from the pick-up, and means operable for varying the value of the alternator current. The test piece 1 is driven by a motor 2, and vertical oscillations due to want of balance actuate two electrical pick-ups 3, 4 in circuit with a valve amplifier 6 and one primary winding 7 of a transformer. The secondary winding 9 of the transformer is connected to a cathode-ray oscillograph 10 where the vertical oscillations produce an approximate sine-curve on the screen. A double switch 5 enables either of the pick-ups to be coupled to the amplifier. The other primary 8 of the transformer is coupled to an alternator 20, also driven by the motor 2, the stator of the alternator being adjustable by a hand-control co-operating with a scale means. The current from the alternator is controlled by a potentiometer 21 or a variable transformer. The arrangement is such that by adjustment of the stator and potentiometer 21 the phase and current of the alternator 20 can neutralize the effect of the pick-up current to produce an approximately straight line on the oscillograph screen. If the stator control is graduated in degrees and the potentiometer calibrated in weight, the amount and position of the weight to be added to the test piece 1 will be given. Specifications 401,569, 498,899 and 549,548 are referred to.
