Title: Ferroelectric system for bulk storage of phase holograms
IPC: G02F1/05
Filed: 1972-09-19
Abstract: 1364766 Ferroelectric hologram stores THOMSON-CSF 19 Sept 1972 [20 Sept 1971] 43389/72 Heading H3B Optical phase holograms are stored in an impurity-doped ferroelectric plate 10, Fig. 1. as a pattern of refractive index variations caused by non-uniform electron distribution, formation of a hologram involving the steps of uniformly polarizing the plate in one sense, directing intersecting object and reference beams 4, 7 from a laser source 1 on to the plate, reducing the polarization of the plate by applying a selected potential in the opposite sense, and finally reapplying the reference beam 7 alone to restore the diffraction efficiency reduced by polarization reduction. The ferroelectric plate has a substantially rectangular hysteresis characteristic at ambient temperature, Fig. 5 (not shown), and consists of barium titanate or potassium niobate doped with nickel, cobalt or iron, the distributed impurities forming traps for migrating electrons liberated by the incident radiation. Polarizing electrodes 11 are provided on surfaces of the plate normal to the crystallographic axis C, the polarizing potentials being applied from a generator 12 which also controls the positions of a beam splitter mirror 2 and a reference beam reflector 8 through alignment and displacement devices 5, 9. In a modification, Fig. 2, the electrodes 13, 15 are located on the major surfaces of a ferroelectric crystalline layer 14, the electrodes being transparent to incident object and reference beams 4, 7 and the assembly being formed by successive deposition on a transparent substrate 16. Erasure of a hologram is effected by the application of a polarizing potential of sufficient intensity, and partial selective erasure may be effected if the electrodes of Fig. 2 comprise two orthogonal sets of parallel conductors. A further selective erasure system is shown in Fig. 7 in which a potential is applied between a conductive grid 34 and a single electrode 35 within the grid. By adjustment of the position within the depth of the ferroelectric material where the reference and object beams intersect a plurality of holograms may be stored in a single plate. The radiation source may be an argon laser operating at a wavelength of 4880 Š.

Abstract: 1,196,948. Hydrodynamic brakes. ALFRED TEVES G.m.b.H. 25 Sept., 1967, No. 43548/67. Headings F2E and F2F. [Also in Division F4] A hydrodynamic brake having a cooling system in a heat exchange relationship with the engine cooling system is characterized in that a thermal switch is arranged in the engine cooling system to actuate an electromagneticallyoperated valve which empties the brake if the temperature is too high. In a compressed air braking system, Fig. 1, low temperature in the cooling system 3 actuates switch 10 to energize left-hand coil 12, so that actuation of the brake valve 7 allows air to pass from reservoir 4 to charging cylinder 5 and force fluid into brake 1. If the coolant temperature exceeds a permitted limit, right-hand coil 12 is energized to connect the charging cylinder directly to air pressure, by-passing valve 7. Fluid then passes out of the brake 1 back to the charging cylinder 5. Switch 10 also completes a circuit to a warning lamp. The arrangement may also be used in an hydraulic brake system, Fig. 2 (not shown).

Abstract: 966,980. Filters for liquids. PALL CORPORATION. Dec. 20, 1960 [Feb. 2, 1960], No. 43693/60. Heading BID. [Also in Division F2] A filter by-pass valve, which opens to allow flow in the event of clogging of the filter, comprises an assembly 53, Fig. 5, screwed on to the inner end of an outlet 52. The assembly comprises a bowed spring disc valve 60, which may be a Belleville washer, supported by its outer periphery on a ledge 62 and normally engaging a seat 61. In the event of the filter becoming clogged, the inlet pressure in a passage 58 causes the disc to flex to allow flow to the outlet 52. The valve is primarily designed for flow in the direction shown, i.e. from inlet 51 to outlet 52 although flow may take place in the opposite direction when the pressure in a space 66 below the valve disc causes the outer periphery of the disc to flex when the filter becomes clogged. However the space 66 may itself become plugged and when flow is required in both directions the valve shown in Fig. 6 is preferably used. In this case, the housing part 63 is tapered below the disc instead of being right angled, and prongs 70 are provided to limit the movement of tne inner periphery of the disc. In a further modification the outer periphery of the disc is clamped. The filter element is preferably of the form described in Specification 830,908.

Abstract: 1281239 Colour television RCA CORPORATION 10 Sept 1969 [18 Sept 1968] 44607/69 Heading H4F [Also in Division G2] In a colour television camera wherein striped colour filters are used to produce a striped image which is scanned to give separable colour component signals, e.g. in subcarriers of different frequencies determined by the spacing and disposition of the filter strips, the luminance response of the camera may extend to frequencies which include the colour signals, giving rise to luminance-chrominance cross talk since such signals are then not wholly separable. A striped neutral density filter or grating is therefore placed at the exit pupil of the camera lens i.e. at the last surface of the lens in practice, the stripes being orthogonal to the (horizontal) line scan direction, thereby modifying the horizontal spatial frequency spectrum passed to the colour filters and reducing the luminance bandwidth. The spatial frequency response of a suitable filter is shown in Fig. 3, where B represents one subcarrier frequency of 3À5 MHz produced by a 45 degrees inclined yellow striped filter, and C is the frequency of 5MHz produced by a vertically striped cyan filter. The stripes of lower transmissivity of the spatial filter are preferably slightly wider than the other stripes, the portion B, C of minimum response being determined by the difference in widths S and W.
