Title: Portable color television camera system
IPC: H04N11/22
Filed: 1968-10-16
Abstract: 1,223,278. Colour television. R.C.A. CORPORATION. 16 Oct., 1968 [18 Oct., 1967], No. 48980/68. Heading H4F. A colour television system comprising transmitting apparatus in which the green G component of an image is picked-up and transmitted continuously while the red R and blue B components are picked-up in separate tubes 12 and 13 respectively and caused to alternate at line frequency, the two resultant signals containing G and (R + B) information being transmitted as separate channels, and receiving apparatus in which the two channels are separated, the (R + B) channel being delayed for the duration of one line, the delayed and undelayed portions of the signal being combined in a switch such that separate red, blue and green components are obtained. The R and B camera tubes 12, 13 are cut-off on alternate lines by pulses 25 and 26, derived from an oscillator 21, which are applied to the cathodes 18 and 19 thereof in order to produce red and blue outputs 28 and 29 at the input to an adder 31. Here the two signals are combined to produce a wave train as at 32. Marker pulses 41 are also added at 31 from waveform 73 in order that the receiver may distinguish between red and blue information. The order of alternation of R and B is itself alternated in alternate frames by means of an inhibiting pulse applied to a counter 24 by a counter 42 to cause counter 24 to advance or retard by one pulse after each frame. Further, the lines of alternate frames, red then blue, are raised or lowered in such a manner that the lines of each of the two fields in each frame are closer together. This is illustrated in Fig. 5 (not shown). The signal at 32 is modulated on to a sub-carrier at 33 and one sideband is suppressed at 35. The green signal at 27 is then added to the resultant (R + B) signal at 36 and passed to the modulating and other stages of the transmitter such that the green signal occupies a band of approximately 0 to 4 MHz and the (R + B) signal occupies approximately 4 to 8 MHz. The frequency spectrum of the transmitted signal is illustrated in Fig. 2 (not shown). At the receiver, shown in Fig. 3, the two channels are separated by means of filters 45 and 47, the channel containing green information being passed to one gun of a tri-gun cathode-ray tube 67. The signal containing (R + B) information is delayed by one line at 51, the delayed and undelayed signal being combined in an electronic switch 52 so as to form red only and blue only signals at the outputs 64 and 61 of the switch. The switch is actuated by means of pulses from a generator 54 which produces two wavetrains 55 and 56 of oppositely phased pulses to operate each section of the switch separately. Generator 54 is synchronized to the transmitter output by means of the marker pulses 41 which are detected at 53. Fig. 4 (not shown) illustrates an electronic switch suitable for use with this invention.

Title: Method for alloying contacts to semi-conductor devices
IPC: H01L21/00
Filed: 1962-12-31
Abstract: 1,015,290. Semi-conductor devices. TEXAS INSTRUMENTS Inc. Dec. 31, 1962 [Aug. 23, 1962], No. 49043/62. Heading H1K. A method of alloying a metal contact to a semi-conductor body comprises subjecting the body and metal to a beam from an infra-red lamp. In one example, semi-conductor bodies are supported on a heat sink member, such as of aluminium or quartz, and, using suitable masking means, areas of aluminium, to form the contacts, are appropriately deposited on them by an evaporation process. A beam of infra-red rays is then directed on to the assembly for a few seconds and causes sufficient heating to fuse the aluminium and cause alloying. The assembly cools rapidly, owing to the heat sink, and damage to the semi-conductor body is avoided. If the body is of silicon, radiation may be effected from the side opposite to the deposited contacts since the silicon is transparent to infra-red rays.

Abstract: 1529799 Radiography EMI Ltd 31 Oct 1975 [13 Nov 1974] 49074/74 Heading H4F A computed tomography scanner in which a fan-shaped spread of radiation beams 14 is subject to angular scanning has means for giving the radiation source a counter-rotation relative to the detectors, e.g. by scanning an electron beam along an elongated anode 13 of an X-ray tube 10, in a scan and flyback mode so that during each scan period of the counter-rotation each beam is maintained parallel to its original direction relative to a body under examination. The invention can also be applied to a scanner using lateral and angular scanning, Fig. 6 (not shown) thus permitting continuous rather than incremental angular scanning. An arrangement is described with reference to Fig. 7 (not shown) in which a cylindrical array of collimating slits is disposed between a rotating source-detector combination, the collimating slits being rotated in the opposite direction to the source and detectors.

Title: Prescence detector
IPC: G01V3/10
Filed: 1971-01-06
Abstract: 1338062 Road traffic detectors M F WILCOX 6 Jan 1971 [7 Jan 1970] 49126/70 Heading G4Q [Also in Division G1] The presence of an object, such as an automobile, is detected by means of inductive loop 1 connected in the tank circuit of oscillator 8 which is tuned to a natural resonance at a lower frequency than that of a second oscillator 20 which is frequency synchronized with oscillator 8, the outputs of the oscillators being connected to phase detector 35. The presence of an automobile tunes the loop circuit to a higher frequency than that at which it resonates in the absence of the automobile, and the phase difference between the outputs is reduced changing the phase detector output. In the initial condition when no automobile is present negative going pips, the period T of which is determined by the phase difference between the oscillator outputs, establish a potential across capacitor 54 representing the ambient conditions and transistors 60, 56, 74 and 75 remain in their conducting state energizing relay winding 86 and hence lamp 90. When an automobile crosses loop 1 the phase difference between oscillators 8 and 20 becomes smaller and the resulting negative going pips at the collector of transistor 35 of period T2 < T1 result in a change in the charge on capacitor 54 which cuts off transistor 56 and hence 60, 74 and 75 causing coil 86 to be de-energized and lamp 93 to light. When the automobile moves away from the location of loop 1 the initial conditions of the outputs of oscillators 8, 20 is reestablished and the signal applied to capacitor 54 is such as to switch transistors 59, 60 on again. If the automobile does not move then the charge on capacitor 54 leaks off through high resistance 57 so that after about 30 minutes transistor 56  begins to conduct again switching on transistors 60, 74, 75 again. When the signals applied to the base of transistor 56 are small e.g. when a bicycle passes over loop 1 low impedance capacitor 69 causes these signals to momentarily cut off transistor 60 and low impedance capacitor 72 also applies a signal to cut off transistor 74 and deenergize relay coil 86 momentarily. Gradual changes in the inductance of loop 1 due to changing temperature or rain do not occur with sufficient rapidity to cut off transistors 56, 60 and the change on capacitor 54 continually adjusts to ambient conditions through the short time constant circuit through resistors 58, 61 and the collector-emitter circuit of transistor 60. Relay 86, 88, 89, 92 may be employed to operate counting mechanisms, traffic control equipments or ticket machines.

Abstract: 1,069,330. Cathode-ray tube circuits. RADIO CORPORATION OF AMERICA. Dec. 3,1964 [Dec. 19, 1963], No. 49250/64. Heading H4T. Metal parts in the structure of a colour television picture tube are de-magnetized each time the receiver is switched-on by providing the colour purity shield 21 (Fig. 2) with windings 31 ... 34 connected in series as shown, and supplied from the A.C. mains input via a circuit including a thermistor 44 and a varistor 45 which operates each time switch 38 is closed to cause an initially high current to flow in the coils due to the high voltage drop across the thermistor (high resistance, when cold) and the low resistance of the varistor with an applied high voltage. An alternating magnetic field is thus produced and as the temperature of the thermistor increases the intensity of such field diminishes and ultimately reaches a negligible value at which point any previously magnetized metal parts will have been de-magnetized. The colour purity shield which is positioned around the frusto-conical portion of the tube (Fig. 1, not shown) is carried by means of four metal brackets (two only 14, 15 being shown in Fig. 1) which together with the metallic side portions 23, 24 of the tube mounting strap (the centre portions, of which the upper one 22 is shown in Fig. 1, being non-magnetic) act as pole-pieces and produce a demagnetizing field within the tube screen.

In the structure shown, Fig. 1, holes injected into the N-type silicon body 10 at 28 from a P-type zone or point contact with an associated gate 29, are stepped along a serpentine path defined between the parallel ridges 18a-18g of an oxide insulating layer by oppositely phased overlapping negative voltage pulses applied to interdigitated electrodes 20, 21. Along the base of each of channels 15a-15f the oxide has alternately thick and thin portions with each digit of each electrode extending over an adjacent pair of thick and thin portions. The locations of the thick and thin portions are reversed in adjacent channels so that the asymmetrical potential wells formed under each electrode digit on application of pulses thereto ensure transfer of the holes in opposite directions in the adjacent channels. In alternative forms the insulation in each channel has a sawtooth section or is of uniform thickness but with alternate sections of different dielectric constant. The preferred structure shown is made by forming a thick layer of oxide overall and then etching through masks and reforming the oxide in two stages. The electrodes, of aluminium, are then formed by deposition and are provided with contact pads 31-35 of chromium, copper, gold, tin or lead, and quartz is sputtered over the assembly to protect it. Read out is effected via strip electrode 30 to which a voltage higher than that on electrodes 20, 21 is applied, the resulting accumulation of holes beneath it affecting the forward characteristics of a heterojunction or the reverse characteristic of a PN or point contact diode located in the vicinity. A suitable detector circuit is described (Fig. 7, not shown) the output of which may be used to cause remjection of the holes at 28.
