Abstract: ELECTRONIC HOLOGRAPHIC APPARATUS                        ABSTRACT    The invention relates to holography and more particularly to an electronic holographic apparatus whose electrical output represents the magnitude and phase  of  coherent  light  reflected  from a three-dimensional object and distributed over the aperture of the apparatus.  The apparatus provides a coherent beam which illuminates the object to create a speckle pattern in an aperture bounding an optical sensing arrangement.  A reference beam derived from the same source as the illuminating beam illuminates the sensing aperture directly and creates fringes in the speckle pattern.  The optical sensing arrangement consists of a charge injection device (CID) camera with plural optical detectors arranged in relation to the speckle pattern to sense the magnitude and spatial phase of each speckle (on the average).  The sampled outputs of the CID detectors are processed to isolate the magnitude and phase information representing the complex optical wavefront of the hologram from irrelevant terms created by the interference process.          The detected information may be used  for such purposes as imaginq,  interferometry, matched filtering or correlation.

Patent CA-2016426-A1 (CA)
IPC: F23G5/027
Filed: 1990-05-09
Abstract: A solid waste disposal unit (10) having a lower, pyrolyzing chamber (15) and an upper, oxidizing chamber (13) separated by a movable plate (32). Waste is deposited in the lower chamber (15). The chambers (13,15) are rotated to move the plate (32) to a first position which seals the lower chamber (15) from the entrance of air. While the chambers (13,15) continue to rotate, a pair of heaters separately heats the chambers. The waste in the lower chamber (15) is pyrolyzed in the absence of air and gives off a combustible vapor that in turn is oxidized in the upper chamber (13). A plurality of venturi jets (44), mounted in the movable plate (32), mix the vapor with air as the vapor passes into the upper chamber (13). Additional air is introduced into the upper chamber (13) through a rotating regenerative heat exchanger (17) recovering heat from the exhaust gases. After the waste is thoroughly pyrolyzed into a char, the rotation of the unit (10) is reversed causing the movable plate (32) to rotate into a new position wherein air is permitted to enter the lower chamber (15) to cause oxidation of the char. This oxidation process continues until the char is entirely consumed and reduced to a sterile ash. Any gaseous products produced will continue to be oxidized in both chambers (13,15).

Inventor: VICTOR KARL-HEINZ
IPC: F16J15/34
Filed: 1990-12-06
Abstract: A gas lubricated contact free sealing arrangement for a shaft, including a seal housing, a stationary sealing ring positioned in the seal housing, and a rotatable sealing ring mounted to and rigidly connected with the shaft.  The two sealing rings work against each other at their sealing end surfaces with an intermediate lubricating gas.  The stationary sealing ring is separated during operation and under a predetermined operating pressure difference from a cylindrical section of the seal housing located towards the shaft by a functional annular gap which is sealed by a sealing O-ring of rubber or plastic positioned in an annular groove, which stationary sealing ring is pressed against the lubricating gas with a pressure determined by at least one pressure spring.  Both the rotatable sealing ring, and the stationary sealing ring are made of a hard sealing material, having a high heat conductivity, as well as a great modulus of elasticity and a high hardness.  The stationary sealing ring has a surface inertia, which is so large that the gap width of the functional annular gap is practically equal, during operation and at an operating pressure difference, to the corresponding construction-dependent annular assembly gap between the stationary sealing ring and the cylindrical section of the seal housing during all operating conditions and is smaller than 0.4 mm, preferably smaller than 0.3 mm.  The sealing O-ring is further constructed as a compensating and centering ring for the stationary sealing ring and, to this end, has a material hardness which is higher than the extrusion threshold of the material hardness at the given gap width and the predetermined operating pressure difference, and is smaller than a material hardness of 90 shore A in accordance with DIN 53 505.  The gas lubricated sealing arrangement is especially suited as a high pressure seal with a long service life.
