Abstract: 1,200,101. Printed circuits. MARCONI CO. Ltd. 22 Dec., 1967 [17 March, 1967], No. 12653/67. Heading H1R. Relates to the accurate positioning of conductive pads of required dimensions on a printed circuit-board by a photo-resist method using a master negative template which is produced as follows: (i) A pad pattern layout is formed on translucent material 1 (Fig. 3) using grid lines 6 as a guide, the pad representations 3<SP>1</SP> being over the ultimately desired size and of opaque adhesive material. Registration marks 5 are also formed thereon and a negative pattern (Fig. 4, not shown) is then photographically produced from the layout and dowel holes are punched in the negative film at marks 5. The pad positions are transparent areas on the film. (ii) A master matrix 9 (Fig. 5), e.g. of metallic sheet or opaque glass, having holes 3 drilled to the desired size of the pads and accurately located at the intersections of the grid lines 6 also having accurately located guide dowel holes 8, is then laid against the said negative film aligned by the dowel holes. A photographic film is then exposed through the mask formed by the combination of the matrix and negative to produce when developed a second representation of the desired pad layout in which the pad representations are accurately located and dimensioned. (iii) A negative mask of the desired interconnecting conductor layout (Fig. 2) is then laid against the said second representation of the pad layout and a master negative pattern is prepared by contact printing on to a film through the combination. A printed circuit-board is then prepared by known photo-resist methods from the master negative. The board is located by the dowel holes in an automatic punching or drilling machine, which is programmed by tape to produce holes at the intersections of the grid lines 6, thus the holes will pass through the centres of the pads. The master negative is fed to a co-ordinate reading machine which produces the programme on the tape.

Title: Improvements in and relating to television systems
IPC: H04N3/10

Abstract: 437,602. Television. COMMUNICATION PATENTS, Inc., 60, Broadway, New York, U.S.A. April 27, 1934, No. 12730. Convention date, June 21, 1933. [Classes 39 (i) and 40 (iii)] A screen for producing a moving light beam of constant intensity at a transmitter, or of variable intensity at a receiver, comprises a plurality of arc gaps in a magnetic field and means for initiating an arc across the gaps in sequential order. The gaps are formed by oppositely located projections of saw-tooth electrodes 6, 7 fed with a direct current insufficient to produce discharge and with an alternating current controlled from a source 18 by means of a valve 15 and a source of potential 16, the peaks of which produce discharges at the gaps. The movement of the arc towards successive gaps is biassed by the field winding 9 and the rate of propagation of the arc is determined by the frequency of the alternating current supply 18. The moving beam is reflected from an object O to a photoelectric cell 21, the output of which is used to modulate a carrier wave. At the receiver part of the received energy, after demodulation of the carrier, is utilized to control an oscillator to maintain the arc of the receiving screen in synchronism, whilst the output which has not been demodulated is applied to the electrodes to control the intensity of the discharge. The electrodes 6, 7 may be provided with rounded projections. Specifications 360,470, 360,941, and 425,723 are referred to.

Abstract: 545,353. Gun fire-control. INDIA-RUBBER GUTTA PERCHA & TELEGRAPH WORKS CO., Ltd., TARRIS, F. J., and WEBB, D. Aug. 30, 1940, No. 13649. [Class 92 (ii)] Relates to hydraulic systems for firing automatic guns of the type having a main control valve 21 for placing the gun firing-device 31 in communication with a pressure-supply pipe line 22 and an exhaust pipe line 29, and in which an hydraulic accumulator 23 is included in the pressure pipe line. According to the invention, in order to provide an emergency manually operated firing arrangement which can be brought into use if the normal hydraulic system, is damaged, a plungerpump 13 is provided which operates in a reservoir ' 12 connected to the accumulator 23, and a valve 34 is operated by the pump to bypass the liquid from the firing-device back to the reservoir In the form shown, between the main control valve 21 and the firing-device 31, a separate emergency pump-casing 10 is provided including the spring-controlled pump-plunger 13 operated by turning a spindle 17 and connected to the valve 34 these parts being shown in inoperative position. The main control valve 21 can then be operated to supply and exhaust liquid to and from the firing-device by ways of passages 37, 45 and pipe line 38. With the valve 21 in the position shown, the actuation of the pump loads the accumulator through pipe 18 and raises the valve 34 so that the reduced stem x allows pressure fluid to reach pasage 45 and pipe line 38 to effect firing. Exhaust back to the pump casing takes place, as the valve 34 falls, through passages 39, 40 in the valve 34 and passage 42 in the pump-casing. In a modification, the valve 34 is dispensed with, its functions being performed by the main valve 21 which is then connected by linkage to the pump-plunger. Specificatibn 500,725 is referred to.

Title: Improvements in or relating to colour television transmission apparatus
IPC: H04N5/208
Filed: 1967-03-23
Abstract: 1,110,885. Colour television. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 23 March, 1967 [26 March, 1966], No. 13668/67. Heading H4F. In colour television apparatus in which three cameras 1, 2, 3 develop green, red and blue signals, aperture correction is effected by an arrangement 7 which responds to a selected one of the colour signals and produces a " contour " signal which is either combined with a signal or signals derived from the colour signals-as illustrated it is combined at 14 with a luminance signal Y derived from the colour signals in a matrix circuit 13-or is combined separately with each of the colour signals (see Fig. 1, not shown). The " contour " signal is derived by continuously comparing the value of the selected colour signal with its value corresponding to a substantially adjacent point. To permit comparison in the horizontal direction the signal is delayed for a short interval corresponding to the traverse of an elemental area and to permit comparison in the vertical direction the signal is delayed for the period of one line or approximately one field. The operations are carried out in stages 15-16 and the results combined in stage 17. Reference is made to the use of a storage tube to permit the generation of a " contour " signal for both the horizontal and vertical directions. The colour signal which is chosen to develop the "contour" " signal is preferably that one which contributes most to image luminance, i.e. green as illustrated, but other signals may be used. When gamma is used the "contour " signal is preferably derived from a non-gamma-corrected signal and combined with a gamma-corrected signal. The selected colour signal may be subjected to a delay in arrangement 7. Corresponding delays are imparted to the other two colour signals by the inclusion of delay lines in channels 5 and 6. Alternatively, compensation for the delay may be introduced by shifting the scanning raster in the camera tube for the selected colour relative to the rasters in the other two cameras.
