Title: Optical random access memory
Inventor: RUSSELL JAMES T
IPC: G11C11/56
Filed: 1992-12-30
Abstract: ABSTRACT OF THE DISCLOSURE       An optical memory is disclosed in which data is stored in an optical data layer capable of selectively altering light such as by changeable transmissivity, reflectivity, polarization, and/or phase.  The data is illuminated by controllable light sources and an array of multi-surface imaging lenslets project the image onto a common array of light sensors.  Data is organized into a plurality of regions or patches (called pages) and by selective illumination of each data page, one of the lenslets images the selected data page onto the light sensors.  Light in the data image pattern strikes different ones of the arrayed light sensors, thereby outputting a pattern of binary bits in the form of electrical data signals.  By selectively and sequentially illuminating different ones of the data regions (pages) on the data layer, correspondingly different data patterns are imaged by the corresponding lenslets onto the common sensor array, thereby enabling many stored data pages to be retrieved by multiplexing at electro-optical speed.

Title: Co adsorbents with hysteresis
Inventor: PENG XIANG-DONG
IPC: B01J20/32
Filed: 1995-04-24
Abstract: The Present Invention is directed to a composition, its synthesis and a process for adsorptive separation of carbon monoxide from gas mixtures using adsorbents, which comprise cuprous compounds on amorphous oxide macroporous supports.  The compositions are prepared by impregnating cupric compounds on supports followed by reduction of the cupric compound to the corresponding cuprous compound.  The reduction can be performed by the use of a reducing gas, preferably synthesis gas at relatively low temperatures up to 150C, preferably preceded by the use of elevated temperature above 250C.  All the adsorbents described in this invention consist of CuCl particles of finite size supported on macroporous support materials including alumina and silica gel.  Among the ingredients used to form supported CuCl fine particles are support materials of low dispersing power, high copper loading, absence of dispersants, and proper post heat-treatment.  The bulk nature of the active component (i.e., CuCl particles) and the resulting hysteresis in desorption provide adsorbents which have both high working capacity and high selectivity for a pressure swing adsorptive separation process.

Patent CA-2151761-A1 (CA)
Inventor: NENOV NENO TODOROV
IPC: F25J3/04
Filed: 1995-06-14
Abstract: A turboexpander, particularly suited for use in a cryogenic rectification system, comprises a center housing rotatably supporting an elongated shaft to opposite ends of which are mounted a turbine wheel within a turbine housing and a compressor wheel within a compressor housing or a brake within a load housing. The turbine wheel has circumferentially spaced turbine blades.  Process fluid is introduced so as to flow through annular nozzles or guide vanes which encompass the turbine wheel.  The guide vanes direct the process fluid through the turbine blades and each extends between a leading edge more distant from the turbine wheel and a trailing edge less distant from the turbine wheel.  Each guide vane is substantially uncontoured between its leading edge and the trailing edge and is substantially thicker at the leading edge than at the trailing edge.  A thermal shield thermally isolates the turbine housing and the process fluid within the turbine housing from the central housing and the lubricant within said central housing.  A labyrinth seal construction along the length of the shaft between the bearings and the turbine housing prevents migration of the lubricant along the shaft into the turbine housing and prevents migration of the process fluid out of the turbine housing along the shaft and into the central housing.  Sealing gas may also be provided to the labyrinth seal construction as an additional expedient to prevent migration of the lubricant along the shaft and of the process fluid out of the turbine. Superior performance is achieved by the relative dimensioning of certain components.

Patent CA-2161360-A1 (CA)
Title: Efficient and secure update of software and data
Inventor: KORN DAVID GERARD
IPC: G06F9/06
Filed: 1995-10-25
Abstract: The invention concerns apparatus for updating a data file,  from an earlier version to a later version.   The invention compares the earlier version with a later version, and derives a transformation, which contains information as to the similarities and differences.   The invention then processes the earlier version, using the transformation, in order to derive the later version, without reference to the later version itself.     The invention allows multiple versions of an original file, such as bank records located at multiple locations, to be  updated  by  transmitting  the  transformation  to  the multiple locations,  instead of transmitting the updated files themselves.   The procedure is highly resistant to interception   of   the  updated   data,   because   the transformation,  in general,  does not contain the entire contents of the later versions.
