Title: Television channel display
IPC: H04N5/45
Filed: 1975-06-02
Abstract: 1512656 Alphanumeric character generators MAGNAVOX CO 2 June 1975 [5 June 1974] 23774/75 Heading H4T A character generator for a TV receiver, e.g. for display of channel number, comprises horizontal and vertical voltage-controlled oscillators 92, 93 respectively receiving horizontal and vertical drive signals of the receiver, a data decoder 96 having a number of outputs a, b, c ... g each corresponding to a selected character segment (see Fig. 4) which may be displayed in response to an address signal. The VCO's 92, 93 supply clock signals respectively to horizontal and vertical counters 63, 64 which control gates68, 69,71,72andflip-flop70. The formation of a character is initiated by pulseforming circuits 160, 170 which control flip-flops 65, 75. Selection of segments according to the output of the decoder 96 is accomplished by gates 78, 79, 81, 82, 83. Gates 78, 79 have inputs from the horizontal and vertical logic circuit. The outputs of the horizontal and vertical counters is shown in Fig. 6 for a two-character display. Coincidence of these outputs results in the required pattern generation. Size of characters is determined by circuit 91 (Fig. 2, not shown) controlling the clock frequencies of VCO's 92, 93. The circuit 91 may comprise a slowly-discharging capacitor which causes the characters to shrink to zero size as they are displayed. A cursive slant to the characters may be obtained by varying the intervals T1, .... T5, Fig. 4. This is accomplished by pulse-width modulation of the outputs of the VCO's.

Title: Improvements in colour photography
IPC: G03C7/25
Filed: 1935-08-27
Abstract: 462,232. Colour photography. ALLISON, D. K. Aug. 27, 1935, No. 23955. [Class 98 (ii)] Two positive images are produced from two colour-component negatives on superposed emulsion layers and coloured with colours complementary to the colours recorded in the respective negatives, and an image in a third colour is printed photomechanically or by imbibition on one of the positive images from a matrix produced from one or both colourcomponent negatives. The colour-component negatives are produced on a bi-pack comprising a front orthochromatic film dyed with Congo Red and a rear panchromatic film. The two negatives are printed on to opposite sides of a double-coated film, and the positive produced from the orthochromatic negative is toned red with an uranium-toning bath and the other positive toned blue with an iron-toning bath. Alternatively, either or both of the positives may be dye-toned, using red or blue basic dyes after mordanting with an iodine bleaching bath or a copper ferrocyanide toning bath. A positive print from the orthochromatic negative is printed to give a negative, which is etched with a solution including hydrogen peroxide to give a gelatine relief. A yellow image is printed using an acid yellow dye from this relief on to either of the two other images, preferably the red image. In a modification, a developed positive print from both negatives on double-coated film is printed in registry on to an undeveloped positive print from the panchromatic negative on a single coated film, which is then processed to form a gelatine relief employed as previously described. -The gelatine relief may also be produced by the bichromate process, the pinatype process, and the relief - development process. The two colour-component negatives may also be printed on to a film having two emulsions on the same side of the support, or a thick single emulsion. The developed and fixed film may be coloured by bleaching and dye-toning the outer image and then chemically toning the inner image, or by differentially iron- and uranium-toning the outer and inner images respectively.

Title: Improvements in or relating to electrically driven locomotives
IPC: B60L5/32
Filed: 1948-09-15
Abstract: 644,752. Current collectors for electric vehicles. GENERAL ELECTRIC CO., Ltd., and TURRALL, J. C. Sept. 15, 1948, No. 24277. [Class 104 (iii)] In an electrically-driven locomotive of the kind including a compressed-air-operated pantograph and a chamber or enclosure containing at least the main electrical circuits of the locomotive, to which access of an operator is prevented until the operation of switching-means to earth or isolate the said circuits, a pressurecontrolled lock is provided to prevent operation of the switching means while the pantograph is in contact with the supply line or lines, the lock being associated with the compressed air circuit of the pantograph in such manner that the switching means can be operated only when the pantograph is clear of the line or lines. The isolating switching means is interlocked with the door of the enclosure and consists of a contact drum, not shown, on a shaft 1 which carries a cam disc 6 provided with a notch 5 in the edge to receive the offset end 4 of a lever 3. The other end of the lever co-operates with a vertical rod 7 mounted on a piston 10 in a cylinder connected to the pressure system of the pantograph, so that while the pantograph is elevated the end 4 of the lever is retained in the notch 5. The switch drum on the shaft 1 is associated with another switch drum (not shown) mounted on a parallel shaft 12 and controlling the auxiliary machines of the locomotive, the shaft 12 also being linked to the exhausting cock 13 of the pantograph and provided with a cam 14 adjacent to the cam 6 on shaft 1. The cam discs 6, 14 are formed with arcuate recesses 17, 18 respectively, so arranged that, in the position shown, the cam 6 and its shaft 1 are additionally held against rotation. In order to enter the enclosure it is first necessary to rotate the shaft 12 clockwise through 90 degrees by a key 15, thereby opening the auxiliary circuits and also exhausting air from the main pantograph cylinder by opening the air cock 13, whereupon the pantograph breaks contact with the line. Spring 19 then operates to raise the end 4 of the beam from the notch 5, enabling the isolating switch to be opened by rotation of the handle 2. This latter action releases the door of the enclosure and also locks the shaft 12, due to the profile of the cam 6 entering the notch 18 in the cam 14.
