Title: Improvements in or relating to television camera tube systems
IPC: H04N5/228
Filed: 1965-05-28
Abstract: 1,069,597. Cathode-ray tube circuits; television; semi-conductor sawtooth and switching circuits. INTERNATIONAL STANDARD ELECTRIC CORPORATION. May 28, 1965 [June 4, 1964], No. 22732/65. Headings H3P, H3T, H4F and H4T. Distortion in a video signal caused by lack of registration between the raster scanned on the target of the pick-up tube with a previously burnt-in (raster burn) raster is prevented by effecting an over-scan during stand-by periods when the target is not receiving image light so that the smaller raster employed during transmission is always within the area where raster burn occurs. The invention is described in connection with a vidicon tube (10, Fig. 1, not shown) the target of which is periodically exposed by shutter means to light (24) from an image, the shutter actuator (23) being connected to switch means (25) so that when the image is obturated an overscan circuit 30 is operative. To produce the overscan respective resistors in series with the vertical and horizontal deflection coils (19, 20) are reduced in value by the connection of further respective resistors in parallel with each. For the horizontal overscan resistor 55 (Fig. 3, not shown) in series with deflection coil (20) is bridged by resistor (65) by means of the diode switching circuit which operates to bring point 66 to earth potential when switch (25) is in the " standby " position, whereas in the " transmit position the diodes are back biased and point 66 is effectively isolated. A similar arrangement, apart from component values, is employed for the vertical (frame) overscan the mode of operation being indicated by pilot lamps (74, 76). For production of the horizontal sweep, line pulses 36 (Fig. 3, not shown) control the sawtooth generator comprising capacitor 44 fed from a constant current source (45 ... 48) the start amplitude being controlled by a potentiometer (39) and the sawtooth being fed to deflection coils (20) via an emitter following circuit (43, 49, 50) having a high input impedance and a low output impedance. The invention is also applicable to camera tubes utilizing electrostatic deflection.

Title: Radio interference reduction system
Inventor: MCQUEEN JACK GORDON
IPC: G01S7/28
Filed: 1960-07-01
Abstract: 989,731. Interference suppression; pulse radar. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 7, 1961 [July 1, 1960], No. 23152/60. Headings H4D and H4L. In a system for the reduction of interference in received pulse signals in a radar system, I.F. signals from the radar receiver are supplied via a logarithmic amplifier 1, which reduces the effect of noise signals in known manner, to a tapped delay line 2, terminated by its characteristic impedance 3, each section producing a delay equal to the pulse width. If the signals contain both information and noise of varying power level the mean level of the output signal from the amplifier will fluctuate with the power level of the interference and to reduce such fluctuations the centre tapping 6 of the delay is fed to one input of a differential amplifier 11 and the remaining tappings are fed via an OR gate 9 to the other input. The OR gate 9 will pass only the greatest of the four signals from the delay line 2, and the resulting difference signal from 11 is supplied via an amplifier 18, which restores the linearity removed by the amplifier 1, to the utilization circuit.

Title: X-ray diffractometer
IPC: G01N23/20
Filed: 1970-05-13
Abstract: 1307570 Crystallograph YEDA RESEARCH & DEVELOPMENT CO Ltd. 13 May 1970 [20 May 1969] 23235/70 Heading G1A In an X-ray diffractometer a radiation counter 50 is supported within a drum 41 mounted for rotation about its longitudinal axis on a gimbal yoke 26, 27, 28 that is rigidly secured to horizontal gimbal shafts 14, 15. An extended horizontal shaft 18, that is integral with gimbal shaft 14 and is coupled to a ganiometer head 19, supports a crystal 20. Precession motion with respect to X-rays from a collimator is imported to the gimbal by a motor 36 whose output is transmitted via a worm 37 and a gear to a drive shaft 34 (as shown in) Fig. 3. The drum 41 can be rotated by a motor 49 and associated gears 47 & 48. The amount of radiation received by the counter 50 is controlled by means of a sector like aperture 51 in a fixed end face of the drum 41 on which is superimposed a rotatable metal disc with a sector like aperture 52, which a rotation provides variable angular widths ## of the aperture. An additional metal disc 55 provided with a plurality of annular slots of different radii serves to define the height of #r and radial position r n  of the aperture with respect to the centre of the drum face. Three modes of operation are described. The first mode involves actuating the drive motors 36, & 49 to set the instrument (i.e. the crystal and the counter) for a particular crystal plane reflection, then maintaining the instrument stationary in this particular setting and measuring the intensity of the reflected rays in terms of the electric pulses from the counter. In the second mode motor 36 and 49 are actuated to displace the instrument to a position in which the respective angular coordinates are somewhat less than the predetermined values corresponding to the particular reflection to be measured, and then discrete stepping pulses are successively fed to drive each motor into and slightly beyond the predetermined value. In the third mode continuous precession of the crystal and counter with respect to particular particles 6 or # values (angular coordinates) is automatically controlled by means of a computer assembly consisting of a desk top calculator, a programmer and an auxiliary storage memory. A further embodiment employing a vicidon tube instead of the counter is disclosed.

Title: Improvements in the manufacture of portland cement in a rotary kiln
IPC: C04B7/44
Filed: 1926-09-27
Abstract: 282,868. Martin, G. Sept. 27, 1926. Rotary kilns.-The output of a rotary cement kiln is increased by causing the gases to pass therethrough at a speed substantially greater than that normally maintained. Preferably a speed of not less than 30 feet per second is maintained in the clinkering and decarbonating zones, and 22 feet per second in the drying-zone, as compared with 22 and 16 feet per second respectively in normal working. The increased speed may be maintained in some only of the zones of the kiln, while the speed of the gases in other zones may be ncrmal or lower than normal. The gases may be drawn through the kiln by a fan, which is protected from overheating by sprays or jets of water, or by passing the gases first through a waste heat boiler. Alternatively water may be injected into the issuing waste gases to cool and force them out of the kiln. Variations in speed may be produced by varying the cross sectioned area of the kiln in different zones. Baffles may be fitted as described in Specification 264,920.

Filed: 1950-10-03
Abstract: 696,829. Tractor-trailer brake system. SOC. ANON. DES TRACTEURS F.A.R. Oct. 3, 1950 [Oct. 5, 1949], No. 24189/50. Class 103 (i). In a tractor-trailer brake system, the brakes for the trailer (not shown) are normally applied by a strong spring and are released by upward movement of the member 39 to compress said spring by actuation of the bell-crank 36 pivoted to the tractor body at 37. The driver's brake pedal 1, when depressed, acts through link 5 on a floating lever 7 pivoted to a further lever 9 at the top and to a link 13 at its bottom end. Initial movement of the pedal 1 pivots lever 7 about its bottom end and causes lever 9 to apply the tractor brakes 11. Further movement of the pedal causes lever 7 to pivot about pin 8 and through link 13, lever 15 and link 18 to operate a valve 19 which opens to atmosphere the space behind the piston 23 in brake cylinder 22, which is normally under vacuum by communication with the reservoir 20. The piston 23, which is shown in the trailer brakes released position, thus moves to the right under the action of the trailer brake springs. The consequent movement of the lever 26, pivoted at 27, thus causes link 30 to rotate lever 15 about the pivot 14 and reclose the valve 19. A brake application corresponding to the degree of brake pedal depression is thus produced on the trailer. A similar system using compressed air is also described.

The loop is secured to the sleeve 11 by drawing the ends through several holes in lugs formed on the sleeve. Alternatively, the loop may be drawn through a single hole in lugs on the sleeve 11 and the ends secured by a sheet metal clamp. As a further alternative, the loop, instead of being passed through the hole at the inner end of rib section 7, may be passed through the hole at the outer end 19 of the rib section. In a simplified arrangement a plastic cord is secured directly to the stretcher 5 and after passing through the hole at the end of rib section 4 is looped around the inner end of rib section 7.
