Title: Three dimensional optical memory
Inventor: HURRELL STEPHEN WILLIAM
IPC: G11B9/02
Filed: 1987-05-29
Abstract: Any number of data layers 1 are laid one upon another to form a three dimensional memory. The data is stored as transparent areas 3 and polarising areas 4. Electro-optical switching of the optical rotators 2 rotates the polarised radiation beam 6 so the polarising areas 4 of the data layers 1 become transparent or reflective. The data layers 1 are set at an angle 5 which is at or near Brewsters angle to the polarised radiation beam 6, to reduce the polarised radiation beam 6 transmission loss. The polarising areas 4 are preferably alternate thin layers of a high and low refractive index dielectric. The switchable optical rotators 2 are preferably thin layers of a liquid crystal or ferroelectric material. The memory is preferably arranged to search for a specific data word, or words, with one beam of polarised radiation 6 to greatly increase the data searching speed. <IMAGE>

Title: Vibratory cleaning apparatus
Inventor: JEKERLE JIRI
IPC: F28G13/00
Filed: 1988-10-27
Abstract: Cleaning intervals of vibratory apparatus for cleaning heated surfaces of a steam generator which are subjected to flue gas containing dust with adhesive caking properties are automatically adapted to the degree of contamination prevailing to ensure an optimum cleaning effect and avoid an unnecessarily long vibration time. To determine the degree of contamination the stroke rate of the vibratory drive cylinder of the apparatus is ascertained at the beginning of each cleaning period within a short measuring interval and compared with a reference value for the surface having the normal degree of contamination. The cleaning interval periods between cleaning and the cleaning times are lengthened or shortened in accordance with the degree of contamination thus ascertained.
Patent GB-2208972-A (GB)
Title: Waveguide switching apparatus
Inventor: CRACKNELL DAVID JOHN
IPC: H01P1/12
Filed: 1988-11-01
Abstract: Waveguide switching apparatus includes a rotor 56 housed in a stator and having a plurality of waveguide passages 57, 58, 59 and 60 therein. The curved passages 57 and 58 are arranged such that the tangents to their centre lines 65 and 66 at their ports are non-radial, and do not intersect at the centre of the rotor 56. This has the advantage that a larger proportion of the rotor area is available for accommodation of cross-under passage 59. The rotor 56 may thus have a smaller diameter than would a conventional rotor, reducing inertia and improving switching accuracy. <IMAGE>

Title: Loading and unloading processing chambers
Inventor: HAYES JOHN
IPC: B65G1/04
Filed: 1990-01-22
Abstract: A processing chamber 1 for food products has a number of treatment floors one above the other. A lift (5) (fig. 2, not shown) transfers incoming products carried on trays from a supply conveyor 3 to any selected one of floors. A similar lift 6 transfers products being discharged from the chamber 1 to a downstream conveyor 4. The lifts are each provided with a transfer mechanism for transferring a tray 12 carrying food product from lift 5 to a floor or from a floor to lift 6 respectively. The transfer mechanism includes a carriage 11 which can travel outboard of the lift 5 or 6 to engage a tray 12 carrying the food products by means of a ratchet member 14. Return movement of carriage 11 draws the tray 12 onto the lift 6, where it is advanced to a discharge position by a further ratchet configuration independently driven tooth 18. Simultaneously with this advance of the tray 12, carriage 11 returns to a disposition in which a second ratchet 15 engages against a rear face 19 of the tray 12. When the lift 6 is aligned with the discharge conveyor 4, a second forward movement of the carriage 11 drives tray 12 forward from lift 6 onto conveyor 4. <IMAGE>

Title: Modular video display for variable size/shape
Inventor: HILLEN SEAN
IPC: G09G3/20
Filed: 1990-11-26
Abstract: A video display unit consisting of a number of display units or modules arranged in a 2-D array which is fed with video signals from an interface unit connected to a convenient point on the array. Each unit preferably comprises a tile-shaped LCD module, enabling the display to be mounted on the wall, and includes its own control circuit on its rear surfaces. Since each unit takes part in decoding the video signals, an extremely versatile display can be realised, in which the overall size and/or aspect ratio may be changed by simply adding units to, or removing units from, the array. To enable interconnection, each unit has a recess lined with contacts at each edge, in a manner similar to a PCB edge connector, and contacts at the adjacent edges of adjacent units are connected by a coupling member. This interconnection arrangement removes the need for complex connections by means of a backplane. Each control circuit adapts its decoding system according to the size of the array and the position of the respective display unit within it, so that video signals which would otherwise be incompatible with the overall pixel array dimension of the display can be successfully decoded.
