Patent CA-2090699-A1 (CA)
Title: Analytical method
Inventor: KELL DOUGLAS B
IPC: G01N33/483
Filed: 1991-08-30
Abstract: Biological cell material, substrates therefor, or inhibitors of cell metabolism are determined by causing an AC electrical potential to fall across a sample of the biological material so as to produce a non-linear dielectric spectrum, and obtaining a detectable signal corresponding to said spectrum. The potential is typically of a first frequency and the measured response is at a second frequency substantially not overlapping with the first frequency.

Title: Apparatus and methods for providing design advice
Inventor: SELFRIDGE PETER G
IPC: G06F9/44
Filed: 1993-03-03
Abstract: A knowledge-based artificial intelligence system which provides design advice. The artificial intelligence system includes a knowledge base of design information. Users of the system indicate an area about which they require design advice. Thesystem provides the relevant advice. Included in the advice is an indication of the "owner" of the advice. The advice and the relationship between the design made by the user are part of a trace of the users' session with the system. The trace becomes pan of a design document for the design. When the design is reviewed, the trace is reviewed as well. The system includes an interface for updating the knowledge base, and if the design review indicates a need to correct the knowledge base, the corrections are made using the interface for updating.  A preferred embodiment of the system is used to provide advice to designers of a large software system concerning the use of an error reporting and handling system in the system beingdesigned.

Title: Cyclonic vapor flow condenser
Inventor: FAY JOHN M
IPC: F26B5/06
Filed: 1993-06-01
Abstract: ABSTRACT OF THE DISCLOSURE    A condenser for removing vapor from freeze dryers and other vessels includes a three-stage cyclonic or turbine-like vapor distributor mounted for rotation about the axis of an elongated horizontal delivery tube extending through the axial center of the condenser chamber.  The delivery tube mounts end and radial spray nozzles for selectively spraying cleansing fluid and sterilizing steam onto the interior surfaces of all components within the condenser chamber, including a plurality of condenser members arranged in radially offset configuration about the delivery tube in an optically dense configuration which requires vapors to impact the cold surfaces of the condenser members before contacting the inner surface of the enclosing condenser chamber.  Optical density is achieved by providing the condenser member as sheets of metal formed with a serpentine passageway between them for the circulation of a coolant.  Alternatively, optical density may be achieved by providing  the  condenser member  as metal  tubing  bent  in serpentine shape with open spaces between the bent sections, and enclosing the array of tubular condenser members in a cylindrical wall spaced inwardly from the condenser chamber.

Abstract: ABSTRACT OF THE DISCLOSURE.            An  improved  method for preparing aqueous dispersions of metal soaps in the presence of an ionic surfactant formed in-situ is described.The method comprises two main steps: (a) partially neutralizing  a  saturated  or  unsaturated fatty  acid  containing between 8 to 28 carbon atoms with an alkali metal oxide or hydroxide including ammonia  and (b)  mixing  the resulted dispersion with an aqueous dis-persion of a metal oxide or hydroxide, said  metal  being selected   from   calcium,  magnesium,  calcined  calcium carbonate, calcined dolomite, strontium, barium  and  any mixture  thereof. The preferred alkali metal used in step (a) is selected from lithium, sodium, potassium and any mixture  thereof.  The  fatty  acid  used  in step (a) is selected from stearic acid, palmitic acid, myristic acid, oleic  acid,  linoleic  acid and any mixture thereof. The concentration of the aqueous dispersion of metal soaps is generally  in the range of between 0.2% to 50% by weight. The aqueous dispersions of metal soaps were found  to  be useful  as  additives  for  improving  the flowability of polymer materials The present invention relates to a novel method for the preparation of aqueous dispersions of metal soaps. More particularly, the invention relates to a novel method for the preparation of metal soaps obtained in  the  presence of an ionic surfactant formed in-situ.

Title: Imaging and ranging apparatus and aiming method
Inventor: JASIOBEDZKI PIOTR
IPC: G01S17/931
Filed: 1993-09-03
Abstract: Abstract An imaging and ranging apparatus has a sensor unit comprising  a  video  camera  in  combination with  an  optical range-finder.  Typically the range-finder is an infrared laser and the camera is sensitive to visible light.  The camera and the range-finder are arranged so that the optical axis of the camera is parallel or co-linear with the signal axis of the range-finder or so that the signal axis of the range-finder passes through the focal point of the camera.  A pan and tilt motor are provided for aiming the sensor unit.  The apparatus may be used as a robot head or mounted on the end of a manipulator.  To aim the apparatus, radiation is imaged from the field of view of the camera.  A patch is stored from said radiation image comprising an area of interest within the radiation image and an adjustment of the pan and tilt motors is estimated in order to relocate the patch to a position within said field of view where the patch is centered about the optical axis.  The motors are then adjusted in accordance with the estimate and radiation is imaged from the field of view.  A patch in the position centered about the signal axis is compared with the previously stored patch and, based upon the comparison, it is determined whether further adjustment of the motors is necessary.

Title: Time Slot Assigner for Communication System
Inventor: GRAY THOMAS
IPC: H04L12/46
Filed: 1993-10-22
Abstract: The present invention relates to a method of assigning data from time slots on an input bus to time slots on an output bus comprised of determining the order of time slots of data in an input frame, determining whether each time slot of data in an input frame is to be located in the same or later time slot in an output frame, or whether it is to be located in an earlier time slot in the output frame.  If each time slot of data of the input frame is to be located in the same or in a later time slot in an output frame, applying each time slot of data of the input frame to the same or a later time slot in the output frame.  If a time slot of data of the input frame is to be located in an earlier time slot in an output frame, delaying for one time slot interval and then applying each time slot of data of the input frame to the same or a later time slot in the output frame.  Thus the order of time slots in a stream of output data is always from an earlier time slot to a later time slot.
