Title: Prevascularized polymeric implants for organ transplantation
Inventor: STEIN JAMES E
IPC: C12N5/0793
Filed: 1992-10-28
Abstract: A method is disclosed whereby cells having a desired function are seeded on and into biocompatible, biodegradable or non-degradable polymer scaffolding, previously implanted in a patient and infiltrated with blood vessels and connective tissue, to produce a functional organ equivalent. The resulting organoid is a chimera formed of parenchymal elements of the donated tissue and vascular and matrix elements of the host. The matrix should be a non-toxic, injectable porous template for vascular ingrowth. The pore size, usually between approximately 100 and 300 microns, should allow vascular and connective tissue ingrowth throughout approximately 10 to 90 % of the matrix, and the injection of cells such as hepatocytes without damage to the cells or patient. The introduced cells attach to the connective tissue and are fed by the blood vessels. Immediately prior to polymer implantation portacaval shunts can be created to provide trophic stimulatory factors to the implants to enhance replication and function.

Title: Automatic bladder scanning apparatus
Inventor: MCMORROW GERALD J
IPC: A61B8/00
Filed: 1993-04-29
Abstract: The automatic bladder scanning apparatus includes a transducer assembly (30), which includes a plurality of individual transducer elements (32). A first plurality of transducer elements are connected into an approximately circular or octagonal arrangement to produce a transmitted signal beam. The data transmission signal is pseudo-random. The returning echo signal is received by another plurality of transducer elements arranged in a preselected pattern. One receiving pattern includes two orthogonal sets of linear arrays, while the other receiving pattern involves an octagonal arrangement. The received signals from the second plurality of transducer elements are processed to form a composite received signal. The composite received signal is then further processed to produce information concerning the three dimension image of the bladder, which information is then used to calculate the bladder volume.

Patent CA-2159293-A1 (CA)
Inventor: ORLITZKY ANTON T
IPC: F16N13/04
Filed: 1995-09-27
Abstract: An automatic lubricator is microprocessor controlled and can be pro-grammed to deliver lubricant to a bearing or the like at selected intervals. A pressure for lubricant delivery in the range of 80 - 90 psi can be attained in less than a minute, but the bulk of the lubricant is kept under a minimal pres-sure of about 7 psi to avoid bleeding. Operation of the lubricator rests upon the use of a minor pressure imposed by a spring to force lubricant into the threads of an auger, so that rotation of the auger by a servo motor controlled by the microprocessor then dispenses the lubricant while at the same time providing a mixing action to the lubricant. Provision is also made for auto-matic shutting off of the lubricator at a preselected temperature.

Title: Self aligning in-situ ellipsometer and method of using for process monitoring
Inventor: HSU JON SHAOCHUNG
IPC: G01J4/00
Filed: 1994-01-14
Abstract: An ellipsometric measuring system is set up in association with a vacuum chamber on a production line for thin film samples. The ellipsometer (8) has a scanner (12) for directing the incident light beam to different locations on a thin film sample (11), and the ellipsometer also has an aperture (13) for limiting the reflected light beam (27) received by the photodetector (36). The scanner implements a method of aligning the incident beam to a selected surface of the sample. The scanner and the aperture are used to provide a finer adjustment of the incident beam with respect to the selected surface. The ellipsometric measuring system further uses test thin film samples with known film thickness and index or refractions to calculate a value for the angle of incidence of the incident light beam.

Patent CA-2174145-A1 (CA)
Title: Marine navigational aid
Inventor: SMITH DARREL R
IPC: B63B49/00
Filed: 1996-05-24
Abstract: When navigating a water channel by boat, it is preferred, and at times crucial, that the boat pass the channel buoys/markers on the proper side. The buoys/markers not only control the flow of marine traffic but also protect boaters from water hazards. While travelling upstream, boaters should keep the green buoys on their port side and red buoys on their starboard side. Conversely, while travelling downstream, boaters should keep the green buoys on their starboard side and red buoys on their port side.      This can be very confusing and in the case of an error it may result in very costly repairs and/or injuries. Boaters must continually be aware as to whether they are going upstream or downstream, and then recall which side of the red and green buoys they must keep to. With all the other decisions and observations that have to be made while navigating a water channel, these important rules can quite easily become confusing. With the "Marine Navigational Aid" the boater only has to determine once the direction to be travelled, i.e. upstream or downstream, and then set the "Marine Navigational Aid" to read in that direction. The correct side to pass by the buoys can be quickly determined by visually observing the placement of the red triangle and green square on the "Marine Navigational Aid".

Abstract: A method and apparatus for generation of a discharge in own vapors of a radio frequency electrode for sustained self-sputtering and evaporation comprising the steps of: (a) generation of a radio frequency discharge by a radio frequency electrode of a hollow geometry in an auxiliary gas introduced into the discharge area at a pressure necessary for an initiation of a hollow cathode discharge inside the hollow electrode causing sputtering and/or evaporation of the electrode surface; (b) increasing the radio frequency power to said hollow electrode to enhance density of vapors containing particles released from the electrode by the sputtering and/or evaporation in the radio frequency generated hollow cathode discharge up to a density at which a self-sustained discharge remains after the inflow of said auxiliary gas is closed and the pumping of gas is adjusted to a value necessary for the maintenance of the discharge. The hollow radio frequency electrode may serve as an inlet of said auxiliary gas.
