Patent CA-2136832-A1 (CA)
Title: Tissue equivalents
Inventor: DAVIES ALBAN
IPC: A61F2/06
Filed: 1994-03-29
Abstract: A method of forming a tissue equivalent is described. A length of polyester tube is threaded over a mandrel (H) and attached at either end by clips at A and D. A block (F) is then screwed into place. The polyester is then pre-soaked by injecting through Tap (2) an acidified collagen solution for approximately one hour. After a suitable period of time the excess solution is aspirated off. Following this stage, a second, alkaline solution is injected into the apparatus which contains smooth muscle cells (SMC). Thus, neutralisation of the collagen impregnated within the fabric of the tube occurs leading to spontaneous fibrillogenesis within the interstices of the cloth, eliminating the risk of delamination. The apparatus is then incubated. The collagen contracts down onto the fabric tube and the cell-impregnated gel becomes incorporated into the presoaked collagen. The pre-impregnated collagen and the collagen provided in the aqueous mixture contract down as one into a coherent whole with the SMC. The tissue equivalent is then lined with endothelial cells and the apparatus again incubated and fed at increasing intraluminal pressures applied either statically or dynamically.  This is believed to cause the vessel to become preconditioned to the pressure it will work under as an implant. This allows organisation of the basement membrane which in turn promotes EC attachment and theoretically prevents smooth muscle cell hyperplasia.

Title: Oxidative dehydrogenation of hydrocarbons with solid superacid catalyst
Inventor: UMANSKY BENJAMIN S
IPC: C07B61/00
Filed: 1994-12-28
Abstract: Solid superacid catalyst, for example sulfated zirconia, is used in the oxidative dehydrogenation of saturated or partially saturated hydrocarbons, for example the conversion of isobutane to isobutylene in the presence of an oxygen-containing oxidizing  agent at reaction conditions typically including temperatures from 500 to 1,000 degrees Fahrenheit, superatmospheric pressures, and oxygen/alkane molar ratios from 0.2 to 20.  Performance of  a  metal-oxide or metal-hydroxide oxidative dehydrogenation catalyst may be enhanced by pretreating a solid superacid or other catalyst containing metal oxides or hydroxides at a carbonizing temperature with an organic material, for example an oxygen-containing organic material, to form a carbonaceous layer on the surface thereof prior to use of the catalyst in oxidative dehydrogenation.
Patent CA-2139704-A1 (CA)
Title: Intelligent distributed control for elevators
Inventor: SHAH DENIS D
IPC: B66B1/00
Filed: 1995-01-06
Abstract: Distributed processing units (DPU) are applied to elevator dispatching and back-up architecture. They are localizing the processing functions by sensing and controlling local devices and serially transmitting up-dates to other DPUs via one or more communication media (18). This makes it possible to confine the wiring to local levels eliminating the need for a centralized processor.        The distributed processing units (DPU) are designed as floor processing units (FPUa,FPUb,...) one on each floor (E1...), car processing units (CPUa,CPUb,...) in each car (2), group processing units (GPUa,GPUb,...) and signalling processing units (SPUa,SPUb,...) in the machine room (22). They all possess intelligence to communicate and to perform local control algorithms.        The distributed control is structured as a neural network, the nodes being implemented by the distributed processing units (DPU). Depending on the function to be processed, there are main nodes (AO,BO,CO...) with additional back-up nodes (Aa,Ba,Ca...) and auxiliary nodes (A1,A2,A3...).        The inventive, distributed control is characterized by modularity, configurability and simplicity, providing reduced development cycle, ease of maintenance and increased reliability.

Title: Dispenser for rolled material
Inventor: MCLEAN MARK
IPC: B65H35/00
Filed: 1995-01-24
Abstract: There is provided a dispenser for rolled material having a pair of side walls and a top panel with cutting means that can be engaged over the material with a supporting back edge being connected through the circular formed male-female connection. The semi-circular side walls are designed in a way that allows the outermost free end of the material to be extended over the cutting edge so as to be easily engaged or grasped to urge the material from the dispenser for cutting a desired length by moving the material downward against the teeth of the cutting edge. The spacing between the inner side of the semi-circular side walls and the free portion of the material provides enough space for an individual's index finger, and therefore the ability to easily grasp a length of material for dispensing.
Patent CA-2142695-A1 (CA)
Title: Coaxial collinear element array antenna
Inventor: HERPER JOHN C
IPC: H01Q21/10
Filed: 1993-08-31
Abstract: An array of collinear coaxial lines (11, 13) utilizes standard size brass tubing (23c, 24c) with brass rods (23a, 24a) inserted therein to establish each half-wavelength coaxial section. A  coupler (20) positioned between each half-wavelength section has outer conductor supports (20b, 20c) and through passages (20d, 20e) for the inner conductor. Inner conductors (23a, 24a) of the transmission line elements (23, 24) are soldered to the outer conductors (23c, 24c) of the respective adjacent transmission line elements so that all elements are excited with the same phase and polarity. Air dielectric between the inner and outer conductors provides a transmission line wavelength equal to that of free space so that the length of each element in the array is a free space half-wavelength long, thereby providing an antenna gain greater than that achievable with transmission lines having solid dielectric supporting the inner conductor.

Title: Spring loaded self-adjusting melt cutter
Inventor: CATES ALLEN ARTHUR
IPC: B29B9/06
Filed: 1994-02-16
Abstract: An improved rotary melt cutter (17) capable of accomodating a wide variation in polymer melt viscosities and melt charac-teristics is provided by use of a controlled pressure spring mechanism (25) which oper-ates in conjunction with each of several inde-pendently articulated knife-assemblies (19) of the cutter (17). The knife-blade (10) cutting-edges (11) thereby maintain near-zero clearance from an extruder die-face (13) from which polymer strands are being ex-truded. The cutter (17) operates more effec-tively with less interruption and fouling than cutters of similar design but which utilize hy-draulic pressure as the means of maintaining near-zero clearance.

Patent CA-2170794-A1 (CA)
Inventor: EAVENSON JIMMY NELSON SR
IPC: F02N11/08
Filed: 1996-03-01
Abstract: In a utility vehicle operable in either a runabout or continuous mode, a foot operated accelerator pedal switch activates a main relay to start the engine and to maintain the engine running as long as the pedal is depressed with a key switch in the run position.  When the pedal is released with the vehicle operating in the runabout mode, the main relay is deactivated and the engine is killed.  Depressing the pedal activates the main relay to start the engine and maintain the engine running.  The key switch is connected to latching relay structure and has a neutral run latch position.  The latching relay structure is operably connected to the key switch and to a parking brake switch.  The neutral run switch position and the latching structure permit continuous running of the engine as long as the parking brake is engaged.  To switch from the runabout mode to the continuous run mode, the operator moves the key switch to the special latch position and engages the parking brake to provide an alternate activation path to the main relay.  Releasing the parking brake or turning the key switch to the off position will shut off the engine.
