Title: Colour video signal generating apparatus
Inventor: KUROKAWA HIROMICHI
IPC: H04N9/077
Filed: 1969-04-01
Abstract: 1,246,904. Colour television. SONY CORP. 1 April, 1969, No. 17032/69. Heading H4F. In a colour video signal generating system in which an image of an object 1, Fig. 1, to be televised is projected via a striped colour filter 7 on to the conversion layer of a vidicon pick-up tube 4, an index signal which is used as a reference signal for separating colour component signals from the output of the pick-up tube is produced in the form of two signals of different frequencies in bands outside the chrominance and luminance signal bands so as to avoid possible interaction therebetween. Colour filter F, Fig. 2, comprises repeating red, green and blue stripes 7R, 7G and 7B, and also includes first and second index image forming portions 9a and 9b comprising alternate opaque and transparent elements 9D and 9W which repeat four and five times respectively for three cycles of the three colour filter elements. Index image forming portions 9a and 9b are disposed on both sides of colour filter 7, and in Fig. 2 two such assemblies are shown as a unitary structure. Lens screen 8 comprising cylindricallenses 8a and flat non-lens portions 8b, Fig. 3, is disposed in front of the pick-up tube with lenses 8a parallel to the colour filter stripes so that three repeating cycles are focused by each lens 8a into images on the photoconductive layer of the tube. The overlapping images of the colour filter and index forming portions are scanned by an electron beam to produce an output signal shown in Fig. 4 comprising a chrominance signal 14c (separated by band-pass filter 13c) centred on frequency 3f L  (where f L  is the signal frequency produced according to the pitch of the lens elements 8a), a luminance signal 14y (separated by low-pass filter 13y) with its frequency lower than 2À5f L  and index signals 14ia and 14ib at frequencies 4f L  and 5f L  respectively separated by band-pass filter 13i. The beat signal 1f L  between the two index signals is detected 18, multiplied 19 to produce a frequency 3f L  and applied to a phase-shifter circuit 20 to form carriers for detection which are applied to synchronous detectors 17R, 17G and 17B. Wide-band red, green and blue signals are thus derived in matrix 16. The index images may be projected on to the photoconductive layer from outside the optical path between the object and the photoconductive layer e.g. by means a half-silvered mirror disposed between filter 7 and lens screen 8, light from a light source being directed through a diffusion plate to index image forming means before being reflected by the half-silvered mirror on to the photoconductive layer of the pick-up tube, Figs. 5 and 6 (not shown). Lens screen 8 may be replaced by a relay lens.

Title: Improvements in or relating to brazed joints between the closure member and the casing of a container
Inventor: FORRESTER ROBERT HENRY
IPC: H02G15/14
Filed: 1956-06-01
Abstract: 829,014. Brazing. SUBMARINE CABLES Ltd. May 31, 1957 [June 1, 1956], No. 17087/56. Class 83 (4). In brazing the closure member to the casing of a container, a sink for flux and brazing material is formed between the surfaces to be joined, the sink having a branch space of smaller cross-section, flux and brazing material are applied at the entrance to the sink and the assembly is heated to melt firstly the flux and then the brazing material, the branch space exerting capillary attraction on both the flux and brazing material whereby the brazing material displaces the flux in the sink and moves it in a direction away from the sink and displaces the flux in the branch space to move it in the opposite direction away from the sink. The counterbored surface 2 of a high-tensile steel submarine cable repeater housing 1 is arranged with the counterbore uppermost to receive a bulkhead 3 having a surface 8 in sliding engagement with the surface 2, a reduced diameter surface 4 which forms a capillary branch space with the surface 2 and a further reduced diameter surface 5 which forms the sink with the surface 2. The surfaces 4, 5 and 2 are coated with flux in alcohol. A coil or a number of rings 9 of lowmelting alloy are arranged adjacent a chamfer 6 on the bulkhead and a thick paste of flux is placed on the alloy. Induction coils 10 on the inside of the bulkhead and outside of the housing heat the assembly while cooling water is passed through jackets 11, 12. The alcohol evaporates and the flux melts to flow into the branch and sink spaces and then at 620-830‹ C. the alloy melts displacing the flux in the sink to the upper surface of the alloy and displacing the flux in the branch space before it. The assembly may be agitated during brazing.

Abstract: 1,183,340. Crop stores. TEXAS INDUSTRIES Inc. 13 April, 1967 [29 April, 1966; 27 June, 1966], No. 17107/67. Heading A1F. A crop store wherein crop is fed under pressure, comprising an elongated storage space such that its length is greater than its height, and a supply channel parallel to the longitudinal centre line of the storage space. Each of the silos 1 has a circular inlet opening 6. A compressing channel 12 at its end adjacent the silo is surrounded by a toothed rack around which chain 14 runs, the latter also cooperating with a toothed rack on support pipe 8. The arrangement is such that the feeding device, balanced by counterweight 10, remains in an upright position whilst communicating with any one of the inlets 6. Cutters are disposed in the channel 12. At the end remote from wall 5 each silo has a crop-delivery device 36 (shown in detail in Fig. 5) comprising a displaceable wall 37 which, on its face remote from wall 5, is supported a worm conveyer 59 feeding conveyer 78 (Fig. 1) and on the other, movable crop catches 48. An electric motor 55 provides the drive to toothed flange 52 that rotates the crop catches in the direction B. In turn gear wheel 50 secured to flange 52 co-operates with toothed rim 51 so that the catches on chain 49 travel in the direction A. An electric motor 77 drives a worm 75 that cooperates with a worm wheel 68 to affect displacements of the wall 37 within the silo. The drive to pinions 65 is via frictional discs 69, whose mutual pressure is adjustable by means of spring 70 and nuts 71. In an alternative arrangement of silos a single third silo replaces the upper pair of silos in Fig. 1. A second form of crop store (Fig. 8) includes a silo 79 and supply channel 84 of a crop feeding mechanism mounted on the displaceable wall. A supporting structure 89 is provided with a shaking gutter 92 that feeds crop from conveyer 93 into the supply channel. The elevator is supported itself from a ground wheel 94. The feeding mechanism may be removed and replaced by a crop delivery device similar to that already described. The third form of crop store (Fig. 10) is characterized in that the crop is delivered to conveyer 172 through a series of openings 164 that can be selectively opened or closed by lever 170. In order to control the resistance offered to the backward movement of the wall during the filling operation there is provided a braking mechanism in which a winch drum is braked when chain 148 is wound off.

Abstract: 1302278 Magnetic storage devices KOKUSAI DENSHIN DENWA KK 10 April 1970 [18 April 1969 30 May 1969] 17120/70 Heading H3B In a method of making a thin film magnetic storage plate, a magnetic film (11) and a conductive film (12) are vapour deposited on a substrate (10) to form a composite film which is then etched to produce parallel strips 14, Fig. 1D, around which a closed magnetic circuit is formed by electrolytic deposition of another magnetic film 19, Fig. 2C. The magnetic film 11 is deposited in a steady magnetic field to establish an easy direction of magnetization, Fig. 3B (not shown). The etching is carried out by chemical attack followed by electrolytic etching, and gives a smooth surface on the strips 14. These strips remain connected at portions 15a, 15b, one or both of which portions is then attached to a power supply so that the magnetic film 19 may be electrodeposited. Parts of the end portions 15a, 15b are then etched away to leave the strips 14 joined in any desired pattern, for example in pairs if two core per bit operation is desired, Fig. 1E (not shown). The orthogonal drive conductors required for storage operation are not shown. In a preferred embodiment, an additional magnetic film 16, Fig. 5D, is vapour deposited on the composite film before etching, and improves the closing of the magnetic circuits around the conductive strips. The substrate may be wholly insulating, or may be a conducting body with a coating of an insulator such as SiO 2 .

Filed: 1973-04-13
Abstract: 1422699 Television RCA CORPORATION 13 April 1973 [17 April 1972] 17791/73 Heading H4F In the fading out of one video source-e.g. a studio camera-and the fading in of a second video source-e.g. an outside broadcast camera -momentary loss of synchronization between the sources may arrive causing disturbances in the resultant display. Attenuation of the entire video signal, including interline blanking/ synchronizing portions, may cause the out of sync signals to be made visible on the display. It is therefore proposed that each video signal (at input 3, 1, Fig. 1) has its synchronization pulses, both line and field, separated out (7) to produce thereform a series of blanking pulses coincident with the interline portions, the blanking pulses being fed as switching pulses to a circuit 13 supplying the multiplying factor Y for an analogue multiplier 9 operating on the total video signal X. The value of Y during the interline portions has a constant "black level" value, while during the line portions it has a variable value set by adjustable D.C. source 15. The video signal at outputs 19, 21 therefore has variable amplitude line portions giving fade-in or out facilities and constant, invisible, interline portions. Detailed circuit diagrams are given using integrated circuit modules Figs. 2, 3, 4 (not shown).
