Inventor: JAMROZ WES R
IPC: G01N21/35
Filed: 1993-04-29
Abstract: A  method   and  apparatus   for   non-contact determination  of  the  moisture  content  in  moving  or stationary mass  of  fibrous products such  as wood  is provided.      The  method  comprises  irradiation  of  a substance with infra-red radiation which is intense enough to  introduce  microstructural  modifications  of  the substance surface.  The moisture content of the substance is  determined  by  analyzing density  of  these  surface modifications.  It has been found, that an optical beam may be used in order to quantify the density of the surface modifications.  The surface is scanned with the optical beam two (2) times.  The first scanning is done prior to the infra-red irradiation; the second scanning is done following the infra-red irradiation.   The invented method  allows  for  non-contact,  rapid  and  continuous in-line measurements of the moisture content.

Abstract: In a communications device, two coherent detection algorithms (102 and 103), one of which has a decision feedback equalizer (103), and a detector selection algorithm (104) are used to dynamically select a detector depending on whether delay spread distortion is present. First the correlation of the detector without the equalizer (102) is measured. If this correlation is greater than a predetermined threshold, the data from that detector (102) is used by the communications device. If the correlation is less than the threshold, the correlation of the detector with the equalizer (103) is measured. If this is less than the correlation of the detector without the equalizer (102), the data from the detector without the equalizer (102) is used, otherwise the data is taken from the equalizer (103). In any case, if the detector without the equalizer is used, the detector with the equalizer is turned off.

Abstract: INTERCONNECTION METHOD FOR DIGITAL MULTIMEDIA               COMMUNICATIONS                 ABSTRACT OF THE INVENTION      A network controller for dynamically rearranging a LAN to    guarantee    bandwidth    required    for    multimedia communications comprises a switch for being connected to the transmit and receive ports of each LAN station and a switch controller.   The  switch  comprises  an  internal  switching fabric such that any receive port can be connected to any transmit  port  of  any  of  the  stations.   The  switch controller, which is connected to the primary LAN, controls the switch so that the LAN may be dynamically reconfigured when, for instance, a LAN node wishes to establish a private session with another LAN node.  The request from the node to the controller is sent in a packet being passed around the primary ring.  After the data transfer is complete between the two stations and they wish to re-enter the primary ring, one  of  the  stations  issues  a  request  to  the  network controller to reconfigure the network.  The request is made by applying a DC voltage to one of the node's receive or transmit line pairs.   The network controller detects this signal  with DC  detection  circuitry  and  reconfigures  the network accordingly.

Patent CA-2108023-A1 (CA)
Inventor: HORNER KENNETH J
IPC: C02F1/44
Filed: 1993-10-07
Abstract: A self-contained, transportable reverse osmosis water purification unit has a limited throughput of no more than about 20 gpm of permeate in a single pass operation with reverse osmosis ("RO") modules which can be cleaned in place. When raw water is particularly fouled, the unit is operated in a double pass operation in which the permeate from the first pass is used as feed for a second RO module. The unit, referred to as a "purification container" "PC" or an ADROWPU because the PC is air-deliverable, comprises an enclosed weather-tight housing having a base on which the major components are removably mounted. For transportability, the PC has the overall dimensions of an ISO container, and is fitted with means to load and unload it on standard carriers. A high pressure pump is required to feed water freed from suspended solids to the RO modules.  The pump also delivers concentrate to a bladder tank where the concentrate is stored under pressure (about 100 psig) to flush a coarse filter automatically when it is plugged, which is often. Fine filters for solids removal are not plugged too often and can be replaced when the unit is not producing permeate. The ADROWPU is unique because of the economy of components used to produce a relatively large amount of permeate from any available raw water source. The placement of the components symmetrically about the center of mass of the PC is essential to allow the PC to be loaded and unloaded uneventfully, even if it is delivered by a helicopter.

Title: Lenticular lens
Inventor: GOLZ THOMAS M
IPC: G02B19/00
Filed: 1993-10-21
Abstract: LENTICULAR LENSES                     ABSTRACT OF THE DISCLOSURE   A lenticular lens containing a multiplicity of multi-sided lenticules useful with reflector lamps provides improved light distribution by having the lenticules oriented to avoid parallelism with a projected light image and distributed in a plurality of zones or bands concentric about said optical center. The size and light-spreading ability of the lenticules in each zone is selected to provide the desired light distribution. Parallelism is avoided by having the lenticules arrayed in a plurality of wedge-shaped sections circumferentially arranged in a circle around the optical center of the lens and extending through the zones with the lenticules in each section arrayed in a uniform, close-packed hexagonal array of parallel rows with the longitudinal axis of one of the rows being radially aligned with respect to the optical center of the lens, so that none of the sides of the lenticules are parallel to the light source image projected off the reflector.

Title: Air conditioning and refrigeration systems utilizing a cryogen and heat pipes
Inventor: JOHNSON DALE T
IPC: F25B47/02
Filed: 1993-11-26
Abstract: A refrigeration system, which conditions the air of a conditioned space via heating and cooling cycles, includes a heat exchanger and, in a first embodiment, heat pipes. A cryogen is circulated through the heat exchanger during a cooling cycle. During a heating cycle the flow of cryogen is terminated and heat is transferred into the heat exchanger via the heat pipes. In another embodiment, the temperature of evaporation of a liquid cryogen in the heat exchanger is selected according to the desired temperature of the conditioned space, via selectable cryogen flow paths which provide different pressures and thus different evaporation temperatures. Vaporized cryogen drives a motor connected to a fan which circulates air between the condi-tioned space and heat exchanger. In still another embodi-ment, the mass flow rate of liquid cryogen is controlled as a function of the degree of superheat in evaporated cryogen exiting the heat exchanger, and as a function of a prede-termined floor temperature of conditioned air discharged into the conditioned space.

Title: Catadioptric optical reduction system with high numerical aperture
Inventor: WILLIAMSON DAVID W
IPC: G03F7/20
Filed: 1994-01-05
Abstract: CATADIOPTRIC OPTICAL REDUCTION SYSTEM      WITH HIGH NUMERICAL APERTURE                   ABSTRACT OF THE DISCLOSURE    A catadioptric optical reduction system for use in the photolithographic manufacture of semiconductors having a concave mirror operating near unit magnification, or close to a concentric condition.  A lens group before the mirror provides only enough power to image the entrance pupil at infinity to the aperture stop at or near the concave mirror.  A lens group after the mirror provides a larger proportion of reduction from object to image size, as well as projecting the aperture stop to an infinite exit pupil.  An aspheric concave mirror is used to further reduce high order aberrations.  The catadioptric optical reduction system provides a relatively high numerical aperture of 0.7 capable of patterning features smaller than 0.35 microns over a 26 x 5 millimeter field.  The optical reduction system is thereby well adapted to a step and scan microlithographic exposure tool as used in semiconductor manufacturing.  Several other embodiments combine glasses of different refracting power to widen the spectral bandwidth which can be achieved.

Filed: 1993-05-04
Abstract: The apparatus disclosed herein employs a grating or scale (13) which concentrates light at a preselected wavelength into the positive (33) and negative (35) first orders while minimizing the zeroth order (31). The scale (13) is illuminated with monoch-romatic light of the selected wavelength and a poly-phase periodic detector (25) has its sensing plane spaced from the scale a dis-tance less than W: 2 tan .THETA. where .THETA. = arcain [.lambda.: P], where W  is the width of the illuminated region of the scale. The period of the poly-phase detector is equal to P/2 so that each detector element (51) or phase responds principally to interference between the positive and negative first orders without requiring magnification or redirection of the diffracted light. Preferably, the distance of the sensing plane from the scale (13) is greater than W: 2 tan .PSI. where .PSI. = arcsin [3.lambda.: P], so that the detector response does not include substantial components from diffraction orders higher than the first.
