Title: Improvements in or relating to audio signal processing system
Inventor: KAHN LEONARD RICHARD
IPC: H04B1/66
Filed: 1968-07-10
Abstract: 1,210,453. Transmission systems. L. R. KAHN, and R. R. GORDAN. 10 July, 1968 [11 July, 1967], No. 32877/68. Heading H4R A wide band audio signal is transmitted over two narrower band channels by modulating low frequency and high frequency parts of the audio signal to frequencies within the transmission capability of one of the narrower band channels and transmitting the middle frequencies of the audio signal unchanged over the other narrower band channel. Pilot signals are transmitted over the two narrower band channels to allow the gains of the two channels to be equated. The pilot tones may also be used to compensate for frequency shift in a carrier system. Fig. 1 shows the system in which the wide band audio signals are applied over lead 9 and occupy the range 50 to 6000 Hz. A band of 365 to 3,400 Hz. is fed to channel 11, via filters 20 and 22, together with a pilot signal of 325 Hz. from oscillator 25. The low frequencies in the incoming signal are separated by the 325 Hz. low-pass filter 32 and modulated and filtered to provide a single sideband in the region 750 to 1100 Hz. which is applied to the second channel 13 together with a 650 Hz. pilot signal derived from oscillator 25. High frequencies from the input signal are separated by a 3À6 kHz. high-pass filter 52, and modulated and filtered in a double modulation arrangement to provide a single sideband in the region 1À4 to 3À8 kHz. which is combined with the pilot and the low frequencies in summation circuit 42 to be applied to the second channel 13. At the receiver 12 the components are filtered out and restored to their original positions for reproduction. The pilot signals from the two channels are fed to indicators 108 and 122 via appropriate band pass filters in order that gain controls 100 and 112 may be adjusted to equalize the channel gains. Variable delay circuits 90 and 92 may also be provided to equalize the time delay in the channels. The signals on the two channels may be corrected for frequency shift in a carrier system by detecting the frequency shift of the carrier and controlling one carrier in a double modulation system to cancel out the frequency shift, Fig. 2 (not shown).

Title: Improvements in or relating to oxygen jet cutting machines
Inventor: SEMPER KENNETH DAVID SEYMOUR
IPC: B23K7/00
Filed: 1961-09-14
Abstract: 956,488. Cutting by fusion. HANCOCK & CO. (ENGINEERS) Ltd. Dec. 14, 1962 [Sept. 14, 1961], No. 32936/61. Heading B3V. [Also in Division G3] In an oxygen jet profile cutting machine using a scale drawing traced by an electronic follower 31 having a lead over the cutting torch 19 and whose movements on a drawing are followed by the cutting torch multiplied by the scale ratio, the image of that portion of the drawing being followed is enlarged by the scale ratio before being applied to the photo-electric device 79, Fig. 6, of the follower. This is stated to reduce errors of contour due to the scale multiplication. The follower has a magnifying lens 76 which focuses the enlarged image on to the bottom surface 78 of a photo-transistor 79 supported by a spring arm 80 on a rotatable tube 81 and vibrated at supply mains frequency by an A.C. electromagnet so as to scan the image. Arm 80 gives the photo-transistor 79 the desired lead so that it moves in an arc when the tube 81 is rotated by the steering motor. Signals from the phototransistor are applied to one stator winding of a two-phase steering motor whose other winding is supplied with a reference voltage. The cutting machine, Fig. 1, comprises a longitudinal carriage 15 driven by motor 41 along rails 13 and carrying a transverse carriage 17 driven by motor 42 and supporting the cutting torch 19. To prevent slip the carriage 15, 17 may be driven through rack and pinion gearing. The plate like workpiece 21 rests on supports 22. The drawing rests on a table 28 movable along longitudinal rails 27 supported on a transversely movable drawing carriage 25 running on transverse rails 24 of a frame 23 secured to the main carriage 15. Rotational movements of the steering motor control a two-arm potentiometer whose two arms control respectively, through amplifiers, the carriage motors 41, 42. The speeds of these motors may be varied by a potentiometer for adjusting the cutting speed. Longitudinal movements of the main carriage 15 are fed back to the longitudinal drawing carriage 28 through 10: 1 reduction gearing 35, 36, 38 and rack 39; transverse movements of the carriage 17 are fed back to the transverse drawing carriage 25 with a 10: 1 reduction by means of pinion 34 and rack 32. In a modification, Figs. 2, 3 (not shown), the drawing carriage 28 has longitudinal movement only whilst the follower 31 is mounted on wheels for transverse movement. In another embodiment, Figs. 4, 5 (not shown), the follower mechanism is separate from the cutting machine and the two are interconnected by a magslip system.

Title: Improvements in or relating to electron discharge devices of the hard type and to electrostatic lenses therefor
IPC: H01J29/62
Filed: 1954-11-15
Abstract: 798,257. Cathode ray tubes. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Nov. 15, 1954 [Nov. 13, 1953], No. 32959/54. Class 39(1). A hard cathode ray tube has an electron lens serving to form the sole focusing means for focusing the crossover adjacent to the cathode to a spot at the screen, the lens consisting of a tubular electrode 5, Fig. 2, and a further electrode 6 biased to form an acceleration lens, the distance between the cathode and the effective end of lens electrode 5 remote from the cathode is less than the internal diameter of the lens electrode 5 so that an optimum spot size is obtained at the target with a smaller potential on the lens electrode 5 than if the above dimensional relationship is not fulfilled. In a modification the desired field is simulated by a construction comprising a layer of resistive material 1, Fig. 3, in combination with conductive rings 10 of progressively decreasing axial dimensions one end of the resistive layer being connected to the second lens electrode 11 and the other end being held at a potential -100 to +500 volts different from the potential of 11 so as to set up a potential gradient along electrode 9, 10. This modified embodiment is used when the diameter of the neck is too small for the lens electrode 9, 10 to have a greater diameter than the distance of its remote end from the cathode, and is useful for tubes having ion traps. If the second lens electrode 6, Fig. 2, extends within the first lens electrode, as shown, the effective end for the dimensional relationship above. referred to is the part of the first lens electrode registering with the end of the second lens electrode while if the second lens electrode is wholly outside the first lens electrode the effective end is the real end. The first lens electrode is at -100 to + 500 volts and the second lens electrode positive thereto. The second lens electrode 6 can be supported from the first by ceramic disc 7. Frusto-conical member 8 screens disc 7 from the lens field and also reduces lens aberrations caused by the aperture at the waist of 6. If conical member 8 is dispensed with, disc 7 is coated with conductive material connected to 6 to enable the magnetic scanning field to be close to the lens field, lens electrodes 5, 6 are made of material of poor electrical conductivity such as non-magnetic steel or bronze so as to minimize eddy current losses. The lens field can be magnetically screened by making lens electrode 5 of ferromagnetic material. Electrode 5 can alternatively be a conductive coating on an insulating tube fitting closely within the tube neck or a conductive coating on the tube wall. Both surfaces of disc 7 can have annular ridges to increase the leakage path.

A guideway for a machine for sorting documents such as cheques, vouchers, receipts and paper money comprises a pair of parallel rails 1 with driving rollers 2 mounted therebetween at regular intervals, a plurality of unitary guideway sections 6 removably mounted on the rails 1 between each pair of rollers 2 and each comprising a pair of side walls 7, a substantially continuous floor 12, and presser rolls 19, 20 mounted to engage the rollers 2. The rollers 2 are made of any material having a low coefficient of friction, e.g. steel, but preferably from a laminated reinforced phenolic material. The rollers are all driven in the same direction by belts from a line shaft. Each section 6 has horizontal bars 4 secured to the outer faces of the walls 7 and detachably connected to the rails 1 by screws. The walls are spaced by tie-rods 8. Double wall partition members 9 are supported between the walls 7 by transverse rods 10 and engage the upper ends of the walls 11 of a series of compartments. The entrances to the compartments are closed normally by pivoted members 12, but any one of them can be raised to deflect a document into a compartment by turning its pivot 13 by means of electrically-operated mechanism. A horizontal cover-plate 15 is pivotally mounted above the members 12 on a transverse shaft 17 mounted in the walls. Deflector plates 16 on the lower face of the plate 15 are disposed so that when a member 12 is raised, its leading edge is behind and above the lower edge of the corresponding plate 16. The rollers 19, 20 are mounted on a shaft 21 journalled in a bearing 22. The midpoint of the bearing is secured to one end of a member 23, the other end of which is pivoted to a frame 18 mounted on the plate 15. The bearing is connected to the plate by a tensionspring 24 which holds the shaft 21 parallel to the axis of the rollers 2. The rollers 19, 20 have an edge portion of rubber or other material having a high coefficient of friction. The end of each shaft 17 is bent at 17a and connected to an actuating bar 25 by longitudinal movement of which each plate 15 may be turned to an inclined position. A toggle 26 holds the bar 25 in the position in which the plates 15 are horizontal.

Abstract: 1,096,367. Two-for-one twisting apparatus; stop motions, warning devices. SOC. DES MECANIQUES VERDOL. July 22, 1966 [Aug. 13, 1965], No. 32979/66. Headings DID and D1F. In two-for-one twisting apparatus, a telescopic stop member is provided which is formed of a plurality of slidable elements and carried by the package support radially and upwardly with respect thereto; the stop member is normally retracted, but should the package rotate, it expands under the action of gravity or centrifugal force or both, to contact a stationary stop and stop the package rotating. A package is arranged on a carrier on a hub 7 mounted in bearings 8 on a driven shaft 2. The shaft is inclined and the package is normally kept stationary by a weight 14 arranged eccentrically of the shaft on a disc 13 fixed to the hub. The stop-member is also mounted on the disc but. in a position opposite the weight. It comprises a rod 23 slidably mounted in a tube, itself slidably mounted in a second tube. An abutment 37 is arranged 180‹-270‹ angularly from the position of the stopmember during normal working of the apparatus. If for any reason the package and carrier rotate, the stop member rotating with them is caused to expand centrifugally, and for part of its travel, by gravity, owing to the inclined arrangement of the spindle, to engage the abutment. Expansion of the stop is limited by split-rings coming against shoulders in the tubes. The stop-member may close a circuit to operate a warning device or a device to stop the spindle rotating.
