The intelligible data may comprise a printed name, account number &c. on a sheet 3 of paper or plastics, and a signature on a paper strip 4, Fig. 2. The hologram 5 may be of the intelligible data and a photograph of the intended card holder, and is produced in or on a transparent plastics sheet 6, Fig. 2, and covered with a transparent plastics sheet 2, or is produced in the sheet 2, Fig. 3. In an alternative embodiment the hologram is formed on an opaque sheet. In the case where the sheet 3 is opqaue, a window 7, Fig. 3, may be formed therein so that the hologram 5 can be reconstituted by transmitted light. An optionally transparent support sheet 1 is also provided. The sheet bearing the hologram may bear photographic or semi-conductor substances so that the hologram can be produced therein by a photographic or electrophotographic process. Readers.-Readers for the cards comprise a source of monochromatic, coherent light, e.g. a laser, and a suitable optical arrangement for reconstituting the hologram and projecting its intelligible image on to a screen, e.g. a vibrating glass or liquid crystal screen. The reader may be such that only the part of the card bearing the hologram is accommodated therein, in which case the visually intelligible data is viewed directly and compared with the reconstituted holographic data on the screen. Alternatively, the whole card is accommodated in the reader and the visually intelligible data is also projected on to a screen.

The motions of the machine are controlled by cams and by a distributer controlling the supply of vacuum to the suction cups. The conveyer may be a belt, as illustrated, or may comprise further reciprocating suction discs. Delivering the products to the bags.-The drawer 78 includes a vertical stripper plate 84 (Fig. 3) normally disposed near the rear end 78a of the drawer but connected to the piston rod 82 of a pneumatic cylinder 81 carried by the drawer. At the end of the forward movement of the drawer a catch 85 on the piston rod engages a resilient catch 86 which holds the stripper plate, while the drawer 78 is retracted, until the suction exerted in the cylinder 81 is sufficient to overcome the resistance of the catch 86 and the stripper plate is retracted into the drawer 78. Where the product is a thin slice, e.g. a slice of ham, the machine includes a horizontal shoe which is pressed down on the slice while the drawer 78 is retracted from the bag. Feeding the bags.-The stack of bags is normally biased upwardly by a vacuum ram. The upward movement is prevented by a catch released temporarily after each bag has been fed. The suction head 46 feeding the bags is carried by an arm 45 (Fig. 1) from a vertical pillar 29 which also carries the drawer 78 so that at each reciprocating movement of the rod 29 along a slot 27 one bag is delivered to the conveyer 16, while another bag is filled. The arm 29 also reciprocates vertically to effect the feed of the bags.

Abstract: 1405409 Colour television EMI Ltd 22 Sept 1972 [8 Oct 1971] 46845/71 Heading H4F A single-tube colour television camera uses a striped filter to produce chrominance and index signals. In one embodiment (Figs. 8, 9, not shown) a filter having stripes at an oblique angle to the line scanning direction of the camera tube in a repeating sequence of transparent, yellow, cyan, magenta, yellow, cyan is used, to provide an index signal at half the colour carrier frequency, the index and chrominance signals being separated by delays equal to 360 degrees of the colour carrier, and an adder and a subtracter. In an alternative embodiment crossed filters as  shown in Fig. 2 are used, green light passing through the hatched portions. The camera tube has a scanning line of width equal to one of the horizontal stripes of the image of the filter on the tube target, and the scanning spot is wobbled at a frequency W 2 , the peak to peak wobble amplitude being equal to the line width. The resulting signal has luminance and chrominance signal components which are selected by low pass filter 7 and band pass filter 8, line delay 42 and adder 43 being included to reduce intermodulation effects between the filter stripes, and line delay 9 and adder 10 being included to restore colour balance of the chrominance signal due to the fact that green light is only passed through alternate horizontal stripes of the filter. The signal from the camera tube is also chopped at 11, 16 at the wobble frequency W 2  and twice this frequency, the signals at the chrominance carrier frequency in the resulting signals being separated by filters 12, 18. The sign of the D.C. components in the outputs of 11 and 15 is detected by low pass filters 13, 19 and limiters 14, 20 and is the same as the sign of the signals separated at 15, 17. The resulting signals of correct sign are added at 21 to provide the index signal. As an alternative to the filter of Fig. 2 a filter may be used having vertical stripes of which every third one is alternately magenta and transparent in different lines, the intervening vertical stripes being cyan and yellow.
