Patent EP-0289642-A1 (EP)
Inventor: VAN ZEGHBROECK BART JOZEF
IPC: G11B7/24047
Filed: 1987-05-08
Abstract: The erasable electro-optic storage disk for use in focused laser beam operated data handling systems compri­ses a semiconductor substrate (11) with a storage layer (14) arranged on top of it that is capable of trapping charge carriers. Electric contacts (15, 16) are connected to the semiconductor substrate and to the storage layer, respectively. An energy barrier (12-13) with associated depletion zone is formed in the substrate (11) near the interface with the storage layer (14). Upon simultaneous application of a control voltage to the contacts (15, 16) and of a focused laser beam (18) directed at a storage site (19), electron pairs are generated in the depletion zone, and charge carriers are transferred towards the interface. This causes a reduction of the depletion zone and thus of the voltage over the depletion zone, and an increase of the field in the storage layer (14), whereby charge carriers are injected into and trapped in the storage layer (14).

Abstract: It has hitherto been permissible to landfill asbestos-containing rubble, as a blend with water. To prevent contaminated soil arising from this in future, it has been proposed to convert the rubble sludge by the addition of cement into unset concrete and allow this to set to give concrete blocks. This process has the disadvantage that safe embedding of the asbestos particles for long periods is not achieved. The new process is intended to overcome this drawback. The new process is characterised in that the surface of the rubble particles forming the asbestos-containing rubble is wetted, before blending with the water and the cement, by the addition of aqueous sodium silicate solution. If necessary, further additives, especially solutions of magnesium or aluminium sulphate, can also be added. The new process achieves enhanced bridging between the very fine asbestos particles and the cement grains which are relatively coarse by comparison, the bridging ensuring secure and permanent embedding of the asbestos particles in the set concrete block even if the latter is exposed to mechanical or weathering actions. Equipment for carrying out the process is also indicated.   The new process and the associated equipment are suitable for embedding all types of asbestos-containing rubble, such as is obtained especially in the renovation of buildings fitted with asbestos-containing building materials. <IMAGE>

Abstract: An electron discharge machining (E.D.M.) tool combination (10) is useful for removal of an installed nuclear steam generator tube plug of conductive material. A conductive wand shaft (12) connected to an E.D.M. voltage source (16) is movably mounted in a housing (20) and insulated from the housing. An inlet adapter (26) is mounted on the wand end and connected to a source (30) of deionized and demineralized water to provide a dielectric fluid and removed material carrier. A hollow electrode (40) is mounted on a hollow extension (36) beyond the end of the wand and inlet adapter (26) in fluid communication with the adapter for movement with the wand relative to the housing. A drive plate (72) is moved by means of a ball nut (74) along a roller ball shaft (76) which is rotationally driven by a motor (82) in the housing (20). The drive plate (72) reciprocates the wand and electrode for E.D.M. operation. The wand position can be monitored remotely by a signal from a potentiometer (92) with a tap (90) movable with the wand.

Abstract: A method for displaying moving objects (targets) is described by means of which two object signatures offset in time are imaged on a detector. The position coordinates of the objects are defined by subtracting the detector output signals of the two object signatures from one another. The method is distinguished by the fact that the first signature scan is delayed in time by means of a buffer store, in such a manner that it is available at the same time as the second signature scan. After subtraction of the signals of these signature scans, the coordinates of the moving objects are defined by the individual signals which are not erased and remain in the store, and are electronically output.

Abstract: A liquid crystal cell (10) includes a chiral liquid crystal material (16) captured between a pair of electrode structures (12 and 14). The liquid crystal material is of a type that exhibits in consecutive order the nematic, smectic A, and chiral phases at successively lower temperatures. In a preferred embodiment, the chiral phase is of the smectic C type. The electrode structures have director alignment layers (22 and 22ʹ) deposited on their inner surfaces. The directors (28 and 30) of the liquid crystal material in the nematic phase in contact the alignment layers align at relatively large tilt bias angles relative to the alignment layer . The tilt bias angles of the directors in contact with one of the electrode structures are defined in a rotational sense which is opposite that of the tilt bias angles of the directors in contact with the other electrode structure. The liquid crystal cell of the present invention is substantially free from smectic plane alignment defects and exhibits substantially uniform director alignment properties. As a consequence, a display device (36) using the liquid crystal cell has an essentially contaminant-free viewing surface and good light extinction properties. Such a display device also has a relatively large off­axis viewing angle.

Abstract: A flexible collapsible container (10) is filled with fluid by connecting a fluid conduit (18) to a tubular port (20) which 
communicates through one of the walls (12) of the container to the container interior, and rupturing a sealing diaphragm 
(24) that closes the bore (34) of the tubular port. One then passes fluid through the conduit to fill the container. Thereafter, 
one seals either or both the tubular port and plastic wall which carries it to the other, opposed plastic wall (14) of the con­
tainer with seal line means to close off flow communication between the bore of the tubular port and a major portion of 
the container interior which contains the fluid. The effect of this is to block flow communication between the bore and the 
fluid so that the contents of the container remain sealed on disengagement of the fluid conduit from the tubular port.
