Abstract: 1,251,790. Image converter. THOMSONCSF. 10 June, 1970 [11 June, 1969], No. 28213/70. Heading H4F. An image converter comprises a layer of photo-conductive material 1, Fig. 1, and a layer of nematic liquid crystal 2 between a pair of transparent electrodes 3 across which a D.C. voltage is applied. In use when radiation 6 to which the photo-conductor is sensitive is incident thereon the voltage across the liquid crystal layer is increased and incident radiation 5 (which is not absorbed by the photo-conductor) is diffused 7 i.e. scattered. Thus if a light image is projected on the photo-conductive layer an image is reproduced by the liquid crystal layer. With no incident radiation 6 the converter acts as a mirror since the face of the photo-conductive layer is smooth. With zinc sulphide as the photo-conductor an incident ultra-violet image is converted into a visible image, and since the photo-conductor is sensitive even to low illumination levels the converter also acts as an image intensifier. If a photo-conductor which is sensitive to visible radiation is used then the photo-conductor layer is isolated from the radiation 5 by a thin layer of opaque carbon black disposed between the photo-conductive and liquid crystal layers (Fig. 3, not shown). The image from a C.R.T. may be projected on to the converter (Fig. 4, not shown) for large-screen projection, and instead of reflecting the auxiliary light beam 5 from the converter it may be transmitted therethrough e.g. by using a semi-transparent mirror between the C.R.T. and the converter (Fig. 5, not shown). Infra-red images instead of ultra-violet images may be converted by an appropriate choice of the photo-conductor material. The nematic liquid crystal may comprise C 1 -anisylidene-p-aminophenylacetate.

Abstract: 1,256,862. Television. BRITISH BROADCASTING CORP. 3 Feb., 1969 [3 Nov., 1967], No. 50169/67. Heading H4F. To test and equalize two video signals e.g. the signals from two cameras televising a scene or the primary colour signals from a colour television camera, the signals are applied alternately by means of a selector switch to a televison image reproducer, and the amplitude of at least one of the signals is adjusted to render identical the brightness of the two recurring images. As shown a grey scale test card 14 is televised by a colour camera 10 and the green- and either the red or blue signals (via manually operable switch 18) are applied to the two inputs of electronic selector switch 15. Switch 15 is controlled by a switching signal from a pulse counter 19 which divides by four line drive pulses from a terminal 21 or mixed synchronizing pulses from terminal 22 so that four lines of each signal are reproduced by a monochrome monitor 23 alternately as a slowly moving (unlocked) or stationary (locked) pattern. For colour balance the outputs at 11, 12 and 13 should be equal for each vertical band of the grey scale chart. In operation the green and red signals are displayed and the amplitude of the red signal is adjusted until the horizontal (four line) bands of different brightness are not visible, and then the same is done for the green and blue signals. Auxiliary inputs 24 and 25 on switch 18 may receive a green signal from another camera to match the outputs of two colour cameras, and a locally generated gammacorrected sawtooth to which the green signal at 11 may be equalized.

Abstract: 1,265,902. Mechanical switches; electric motor controllers. G.A.F. CORP. 18 June, 1969 [24 June, 1968], No. 30775/69. Heading H1N. [Also in Divisions G2-G3] A slide projector 14 has a random selection system comprising detachable slide indexing unit 12 remotely controlled by unit 10 to bring any one of the slides in rotary tray 198 to the projection position, the tray being rotated in a direction giving the least rotational displacement. The system may also be used with linear slide trays. Rotation of selector knob 18 on unit 10 locates a selected slide number on scale 30 beneath mask 26, the scale being carried on a disc 28, Fig. 6, which is thereby rotated on shaft 56, Fig. 7. The underside of disc 28 carries arcuate contacts 49, 50 of opposite polarity with insulating spacers 51, 52. Detent teeth 46, 47 are selectively engaged by springs 140, (141) or 150, 151 for forward or reverse indexing. "Initiate" button 22 closing contacts 42, 44, Fig. 20, is then pressed to energize a motor 162 driving a commutator device on shaft 173 in unit 12 which provides pulses to a D.C. stepping motor 97 in the remote unit 10. Motor 97 then incrementally rotates gears 62 or 74 coaxial on shaft 56 in a direction determined by which of the contacts 49, 50 is wiped by a seeking contact 71 fixed on gear 62 or a contact 82 fixed on gear 74. Rotation continues until contact 71 reaches a spacer 51 or 52, when the circuit of motor 162 is broken. Motor 162 also drives indexing gear 196 engaging rack teeth 197 on slide tray 198 which is thereby rotated until contact 71 reaches the selected slide position. A selector switch 24 is set for a "100 slide" or "80 slide" tray and engages the drive from motor 97 to gears 62 or 74 through pinions 95 or 94, the gears having corresponding numbers of teeth. Movement of switch 24 also moves a mask to expose the "80 slide" or "100 slide" scales 30 in window 25, and sets a switch 101 to connect either of contacts 71 or 82. Single step forward or reverse indexing is possible using buttons 21 or 22 which also close contacts 146, 155, Fig. 20. When "initiate" button 20 is pressed, solenoid 214, Fig. 16, is energized to release pawls 201, through arm 209, from locking engagement with indexing gear 196. A further solenoid is energized to close "load" switch 264 to operate a half cycle of the slide changing operation in which a slide is removed from the gate. Tray 198 is then rotated until the selected slide is at the projection position when the solenoid is de-energized together with motor 162; the changing cycle is then completed to move the new slide into the gate.
