Filed: 1947-07-26
Abstract: 633,897. Moving signs. AITKEN, H. J. P. July 26, 1947, No. 20188. [Class 3(i)] In a display apparatus comprising an endless band 23 which is moved intermittently or continuously past an aperture or apertures and upon which is mounted the matter to be displayed, the band is secured to and supported by cross members 45 which are connected to side chains 22 which pass over guide wheels mounted on each side of the band, the side chains being operatively connected to move in unison. The side chains 22 are guided over a pair of sprocket wheels 11 and pairs of grooved guide wheels, as shown in Fig. 3, and are adjusted for tension by screw-and-nut means which varies the angular position of supports 15 on which the sprockets 11 and guide wheels 12-14 are mounted. An electric motor 53 drives each chain independently through the guide wheels 8 which in turn are chain-connected to the wheels 7, 10. These driven wheels are independently mounted on fixed spindles on plain bearings; the idler wheels are mounted on ball bearings on fixed spindles and the sprocket wheels 11 are fixed to a common rotatable shaft to keep the chains moving in unison. Idler rollers 64 prevent the weight of the band forcing the chains 22 off the sprockets 11. The band 23 is pinned to the cross rods 45, arranged alternately on each side as shown in Fig. 5, and also sewn, and these rods are attached to the chains 22 by flexible connections 46 which ride on the inner flange of the guide wheels so that the band follows the wheel contour. In an alternative construction the rods are attached by brackets to the chain and the band may be held to the rods by press studs or clamps. Sprocket wheels with or without a flange to support the flexible connections 46 may be used in place of the guide wheels. The supporting frame is mounted on castors 54 and is enclosed in a casing, the viewing aperture 37 having electric lamps 42 mounted on each side.

Title: Improvements in or relating to swept frequency oscillators
Inventor: SEYMOUR RONALD ARTHUR
IPC: H03B23/00
Filed: 1960-06-09
Abstract: 986,633. Automatic voltage control systems. H. M. POSTMASTER GENERAL. June 1,1961 [June 9, 1960], No. 20355/60. Heading G3R. [Also in Divisions H3 and H4] An oscillator is both swept and controlled in frequency by applying its output to a frequency detector to derive a reference signal bearing a linear, logarithmic inversely logarithmic or other relation to the frequency which reference signal is then additively combined with a sawtooth or other variable amplitude external signal so that the external signal frequency sweeps the oscillator and yet the combined signal is maintained substantially constant. The oscillator may be a modified Wien bridge transistor R-C oscillator VT1- VT3 with identical networks N 1 -N 2  corresponding to the capacitances; the input to R 1 , MR3, R 2  controlling the oscillator frequency by varying the resistance of series and shunt rectifiers MR1, MR2; VT4 being a voltage clamping circuit setting a lower limit to the oscillator frequency. The oscillator output is amplified at VT5-VT7 and passed to an amplitude limiter and slicer VT9,yT10 producing a rectangular wave and to emitter follower VT10 preceding a diode pump frequency meter circuit MRS, VT12 with output applied through VT11, VT13 to a comparator circuit VT14, R7, R5 with other input, e.g. sawtooth, applied at A. The thus added inputs to VT14 have subtracted from them a constant bias voltage applied to the emitter of VT14 and the difference amplified by VT14 passed through a smoothing circuit R9, C4 to the input circuit R1 MR3, R2 controlling the oscillator frequency sweep. A loop comprising amplifier VT17-VT20 and detectors MR6,MR7 produces an output dependent on the difference between the amplified oscillator amplitude and a standard voltage set by potentiometer VR1 and Zener diode MZ1, and is applied to vary the resistance of a diode MR4 shunted across the oscillation feedback loop N3 of the R-C oscillator, to maintain its output amplitude constant. In a modification the frequency detector is a conventional diode pump circuit fed by an emitter follower whose input is shunted by a ladder network of series resistors and shunt capacitors, so that the frequency detector output is inversely proportional to the logarithm of the frequency.

Title: Improvements in or relating to scanning in radio echo systems
IPC: H01Q1/18
Filed: 1945-08-08
Abstract: 597,429. Electric control systems. WILLIAMS, F. C., and LLEWELIN, A. I. Aug. 8, 1945, No. 20393. [Class 40 (i)] [Also in Group XL] In a radio echo system involving mechanical scanning, the effect of movement of the scanning member about an axis, e.g. due to roll of a craft, is corrected by utilizing an electrical component of control for the scanning member dependent both on the instantaneous angular movement about the axis and the instantaneous position of the scanning member in the scan. The directional aerial of a radio echo system on an aircraft is moved to scan a horizontal line forward of the craft and the line of scan is maintained horizontal despite banking of the craft by elevating or depressing the aerial perpendicular to the "uncorrected" line of scan. In Fig. 1 a gyro (not shown), produces an A.C. signal, dependent in amplitude and on the angle and direction of banking of the craft, which is applied to the primary 1 of a transformer T1, two similar secondaries 2, 3 of which are connected in series with a centre tapped potentiometer 6 across a D.C. source. The slider of potentiometer 6 is reciprocated to provide a D.C. signal controlling a normal scanning motor (not shown). This signal is obtained at 9 after eliminating the gyro-produced A.C. component by means of a filter 7, 8. An A.C. signal, the amplitude and phase of which depends both on the angle and direction of banking of the craft and on the instantaneous position of potentiometer 6 (i.e. the position of the aerial during scan), is applied to the primary 11 of a transformer T2 the output of which is introduced into the grid-cathode circuit of a pentode 13. This valve is rendered operative during alternate half cycles only by coupling an oscillator, having a frequency equal 'to that of the gyro output, to the suppressor grid via 14. A diode 15 conducts during the operative half cycles. The signal at 17 for controlling a correcting motor moving the aerial perpendicular to the " uncorrected " line of scan is taken from the anode of valve 13 through filter 16 and it is demonstrated mathematically that approximate correction is obtained. Introduction of an anti-lag network, correction for the effects of pitch or yaw, and application to systems of spiral or helical scanning are referred to.

Title: Device for Measuring Deviations in a Dimension of a Rotatable Body.
Inventor: KREIENSEN KURT
IPC: G01B7/28
Filed: 1967-05-04
Abstract: 1,183,756. Measuring dimensional variations electrically. GERHARDT MESSMASCHINENBAU K.G. May 4, 1967, No.20718/67. Heading G1N. In the measurement of the variations in diameter of a rotating body, e.g. a shaft or ball bearing, wherein a signal indicative of the diameter of the body is produced, a compensating signal indicative of the average diameter of the body is subtracted in the transducer from the measurement signal to give an output signal indicative of the diameter variations, which is then amplified and fed to a meter. As shown Fig 1, during the first part of a measurement cycle an A.C. energized transducer 1, whose follower 2 rests on a rotating test shaft 3 on a table 4, provides a signal indicative of the diameter of the body which is fed via amplifier 12, and phase-sensitive rectifier 8 to a capacitor 20 which is charged to a voltage dependent on the average output from the transducer. Programmed switch 19 then connects the capacitor to a valve 23 which supplies via cathode resistor 26 a D.C. voltage, dependent on the voltage to which capacitor 20 was charged, to control the elements, e.g. diodes, of an A.C. bridge circuit 10 whose output supplies an anti-phase voltage of corresponding amplitude to the transducer 1. The transducer output is therefore, during this second part of the measurement cycle, indicative of deviations of the diameter from the average, and is, after amplification, indicated on meter 15. In a modification the capacitor 20 is permanently connected to the valve 23, the switch 19 providing an "on-off" contact between the capacitor and the phase-sensitive rectifier 8.

Convention dates, Jan. 14 and Jan. 20. [Class 38 (iii).] Varying E.M.F.-The excitation of the generator L of a Ward Leonard system is regulated by means of a counter-voltage machine D driven by a shunt machine A which is switched on simultaneously with the excitation so as to ensure strong starting torque of the working motor R when regulated for low speeds. In the arrangement shown, regulation is effected by control of the excitation of the machine D by means of opposed field windings d<1>, d<2> and a resistance s, whereby the machine may either oppose or boost the line voltage. In order to prevent instability at low speeds, the excitation circuit of the generator L may include part of resistance S, or an additional winding connected to the brushes of machine D may be provided on the field of the generator L, so that the opposing voltage of machine D is not brought near to the line voltage. The machine D may be constantly excited and its voltage regulated by brushshifting. The switches s<1>, s<2> may be constructed so as to connect machines A and D across field windings on the generator L when in the " off " position, so as to destroy remanent magnetism in machine L during the slowing down of machines A and D. Fluctuation of speed with load of the working motor may be counteracted by providing a supplementary field winding on machine D, connected across a lead connecting the armatures of machines L R.
