Abstract: 1,232,133. Television. BRITISH BROADCASTING CORP. 16 Jan., 1970 [20 Feb., 1969], No. 9329/69. Heading H4F. Two adjacent frames of a motion picture film 16 which is intermittently pulled down one frame by a mechanism 18 are scanned simultaneously by a flying spot scanner comprising a cathode-ray tube 12, twin lenses 14, 14 and 20, 20, and photodetectors 22, 24 and a switch 34 connected to an output 32 is synchronized with the mechanism 18 to pass the direct signal from detector 22 when the film is stationary and the signal from detector 24, delayed 30 for a substantially integral number of fields, when the film is moving. In a preferred embodiment, the line 30 provides a delay of one field Œ one half line period, and the spacing of the two flying spot images at the film is one film frame pitch Œ one picture line pitch. In a modification, the switch may be arranged to pass both the signals at 26, 28 to a combining circuit, except when either signal is unusable due to pull down, when only the other signal is passed. The separation of the lenses 14 may be servo-controlled, e.g. by arranging that, during field blanking periods, the line scan of the tube 12 is perturbed to scan the film sprocket holes, when the outputs 26, 28 should be time coincident.

Abstract: 1,258,633. Modulating light. DEFENCE, SECRETARY OF STATE FOR. 12 Jan., 1970 [15 Jan., 1969], No. 2299/69. Heading H4F. Some electro-optic crystals, such as lithium tantalate and lithium niobate, have a half wave voltage, i.e. the voltage required to cause the crystal to act as a half wave plate, which is a minimum when the applied field is in a certain direction oblique to the X, Y and Z axes. Thus, as shown, a light modulator comprises identical electro-optic crystals 2, 3 having parallel fast axes N, N, and P, P, and provided with transparent tin oxide electrodes for applying electric fields in the direction XX at 55 degrees to the Z axis in the Y-Z plane. XX is also the direction of light, polarized in the plane RR or QQ at 45 degrees to the axis NN, which is passed through the crystals. To compensate for retardation produced by the inherent anisotropy of the arrangement, which would otherwise add to the electro-optically induced retardation, a half wave plate 4 with a part axis OO at 45 degrees to NN is positioned between the crystals. If now quarter wave voltages of the same magnitude but opposite direction are applied to the two crystals incoming plane polarized light will be converted to its orthogonal form, but will be wholly unaffected in the absence of such voltages. The emergent forms may be separated, e.g. by a Wollaston prism, forming one stage of a digital light deflector.

Abstract: 1289506 Windscreen wipers WESTFALISCHE METALL INDUSTRIE KG HUECK & CO 6 Oct 1969 [8 Oct 1968] 48916/69 Heading A4F [Also in Division H2] Apparatus for providing intermittent operation of a windscreen wiper motor M comprises a timing device, including resistors R1 to R5 and a capacitor C1, and operable on actuation of a changeover, switch U by the motor M to energize, at regular intervals, a relay A to close a switch a1, which energizes the wiper motor M, and open a switch a2, which when closed connects the capacitor C1 to a negative supply terminal. When the main control switch S is closed initially a transistor Tr is rendered conducting to energize the relay A and start the motor M. During the very short period before the arm of the changeover switch U is moved by the motor M away from the contact Ul, the capacitor C1 is charged via line L2. When the switch arm moves to the contact U2 the base of the transistor Tr is connected via resistors R2, R3 to the negative supply line, and via resistors R4, R5 to the positive supply line. If the adjustable resistor R5 is set to a sufficiently high value the transistor Tr and the relay A are de-energized to open switch a1 and close switch  a2 to stop the motor M. The current flow through the resistors R4, R5 continues so that the transistor Tr is again energized to repeat the cycle. If the resistor R5 is adjusted to a sufficiently low value the transistor Tr remains continuously energized and the wiper motor M runs continuously.

Abstract: 1297131 Valves HYMATIC ENG CO Ltd 23 March 1970 [25 March 1969] 15606/69 Heading F2V [Also in Division F4] The effective area of a Joule-Thomson expansion orifice is automatically varied by a valve member whose operating mechanism includes a damping chamber for damping out vibrations of the valve member. The damping chamber is filled with a loose particulate material which may comprise phosphor bronze balls or tungsten carbide powder. As illustrated, an infra-red detector 15 mounted in a Dewar 12, 13 is cooled by nitrogen which is passed to a Joule-Thomson orifice 25 through a finned heat exchange tube 11. Low pressure nitrogen returns over the outside of the tube 11. The orifice 25 is controlled by a valve member 30 which is moved through rods 32, 33 and 34 by a bellows 31 at the upper end of the heat exchanger. The rod 32 carries the damping chamber 50. The space 17 surrounding the bellows 31, together with a sensing tube 40 is filled with a two phase fluid which may be nitrogen or methane. The tube 40 has a flattened tail 41 adjacent the load 15. The bellows is so designed and placed that when there is no pressure difference across  it, it contracts to open the valve. Thus, in the event of leakage occurring to the space around the bellows, the refrigerator will continue to provide cooling. The location of the bellows at the end of the heat exchanger allows the latter to be constructed with a small diameter. Movement of the valve member is limited by the abutment of a hooked end of the rod 34 with the edges of an opening in a member 21. In an alternative construction, not shown, the rod 32 is itself hollow and forms the damping chamber.
