IPC: A61L27/48
Filed: 1996-03-08
Abstract: L'invention a pour objet un biomatériau prévu pour être utilisé en chirurgie sur l'homme. Il comprend une couche cohérente d'un tissu collagène non humain qui a été soumis à un tannage au glutaraldéhyde afin de comprendre des fibriles de collagène non réticulées, et un matériau de renforcement de synthèse encastré dans cette couche cohérente. Le matériau de synthèse présente une structure favorisant cet encastrement, la densité moyenne de cette structure étant in situ supérieure à 50 par centimètre carré. L'invention a également pour objet des améliorations d'un procédé de fabrication de biomatériaux consistant à favoriser la croissance d'un tissu collagène sur des structures en mailles recouvrant des surfaces de support implantées chez l'animal. Selon un aspect, une structure en mailles de fibres synthétiques tubulaires s'insère de manière lâche sur une tige ou un tube de support. Selon un autre aspect, on utilise un support formant feuille et le tissu se développant autour du support formant feuille est adapté pour former une poche, un sac ou une enveloppe de matériau collagène.

Title: Method for adjustment the linear increasing of lens return system with nonparalel run of the beams between the components
Inventor: TODOROV ANTON TS
IPC: G02B7/00
Filed: 1989-10-06
Abstract: The method is applied in optics. It reduces the number of regulating operations and drops the need for periodic control. The method: at a certain distance in front of the incoming light diameter of the lens system (1), which is subject to orientation is placed an exemplary scale (3) with an access field (10) of the linear augmentation so that its geometric centre lies on the optical axis, where sits the geometric center of a second scale (2), situated behind the inverting system (1). Through axial displacement of a strong optical element, the linear augmentation in the access field (10) is regulated, after which the optical elements (1 and 2) are fixated. The scale (2), located after the system (1) following the path of rays, is its own scale. The strength optical element is the entire inverting system (1), whose axial displacement precedes the axial displacement of the exemplary scale (3) until receipt of its clearest image onto the scale (2) of the inverting system (1).

The sublimated carbon dioxide is then absorbed  by the packaged product, avoiding collapse of the package.
Patent CA-2003338-A1 (CA)
Title: Synchronization of fault-tolerant computer system having multiple processors
Inventor: CUTTS RICHARD W JR
IPC: G06F9/52
Filed: 1989-11-20
Abstract: ABSTRACT:      A computer system in a fault-tolerant configuration employs three identical CPUs executing the same instruction stream, with two identical, self-checking memory modules storing duplicates of the same data. Memory references by the three CPUs are made by three separate busses connected to three separate ports of each of the two memory modules. The three CPUs are loosely synchronized, as by detecting events such as memory references and stalling any CPU ahead of others until all execute the function simultaneously; interrupts can be synchronized by ensuring that all three CPUs implement the interrupt at the same point in their instruction stream. Memory references via the separate CPU-to-memory busses are voted at the three separate ports of each of the memory modules. I/O functions are implemented using two identical I/O busses, each of which is separately coupled to only one of the memory modules. A number of I/O processors are coupled to both I/O busses.

Title: Point-of-sale data gathering system
Inventor: MILLS NIGEL G
IPC: G06V30/224
Filed: 1990-01-29
Abstract: Abstract of the Disclosure A two part data gathering system for use in a checkout counter to determine information relating to products to be purchased comprises a scale supported within the checkout counter for determining weights of products, the scale including a load receiving subplatter located below the upper surface of the counter.  An optical scanner is supported upon the load receiving subplatter for reading coded labels on the products.  The optical scanner has an upper surface including an optical scanning window through which scanning light beams pass and is vertically positioned such that its upper surface is substantially aligned with the upper surface of the checkout counter when the optical scanner is supported upon the scale subplatter.  The weight of the optical scanner is eliminated from the weight readings provided by the scale and the upper surface of the optical scanner becomes the scale weighing platter for receiving products to be weighed by the scale.  The two parts of the data gathering system, i. e. the scale and the optical scanner, can be separately manufactured, packaged, tested and shipped to the field where they are individually installed to ease and facilitate installation and removal of the two part data gathering system.

Title: Pressure-responsive fuel delivery system
Inventor: TUCKEY CHARLES H
IPC: F02D33/00
Filed: 1990-02-14
Abstract: ABSTRACT OF THE DISCLOSURE    A fuel delivery system for internal combustion engines in which an electric-motor fuel pump supplies fuel under pressure from a tank to a fuel injector carried by the engine, and excess fuel is returned by a pressure regulator from the engine to the supply tank.  A restriction is positioned in the fuel return line to restrict flow of return fuel therethrough, and thereby create a back-pressure of fuel in the return line.  A pressure sensor is coupled to the return line between the pressure regulator and the restriction and drives the fuel pump as an inverse function of fuel pressure in the return line, and thus as a direct function of fuel demand at the engine.

Patent CA-2014337-A1 (CA)
Inventor: GOULDING PETER
IPC: G01N1/24
Filed: 1990-04-11
Abstract: A method and apparatus for measuring a parameter of a test gas in isolation from gas pressure fluctuations.  A pump draws the test gas through an air capacitor into a sensor, storing the gas in the capacitor. A valve closes a fluid flow path which admits the test gas to the air capacitor and opens a fluid flow path between the air capacitor and a constant pressure alternate gas source, isolating the air capacitor and the sensor from pressure fluctuations in the test gas. The air capacitor prevents any mixing of the test gas with the alternate gas until measurement of the unknown parameter has been accomplished.

Title: Heating and cooling system for air space in a building
Inventor: DICK BRIAN G
IPC: F24F3/00
Filed: 1990-07-24
Abstract: HEATING AND COOLING SYSTEM FOR AIR SPACE IN A BUILDING          ABSTRACT OF THE DISCLOSURE     A  reversible  refrigeration  plant  serves  as  an air conditioner for cooling air or alternatively as a heat pump  for  heating air.   Functions  of  a   refrigerant evaporator  and  condenser  are  reversed  in  the  different modes. A main stream of inlet air is divided into separate main and bypass streams of air. The main stream is heated by the condenser of  the heat pump and flow between the main stream and the bypass stream is varied in an inverse ratio so that as flow through the bypass duct increases, flow through the main duct decreases and vice versa. Also, as  a  desired  air  space  temperature  is  approached, preferably heat  rejected  at  the  condenser  is  gradually reduced  by  reducing  refrigerant  flow  therethrough  by modulating compressor  suction.  Also,  energy is  saved  in both  the heating  and  cooling modes  by  locating  a  heat exchange coil within an exhaust flow of  air discharged from the space to be heated or cooled.

Abstract: This disclosure describes a double-sided transmission substrate formed with striplines and end-ports in juxtaposition on either side. The transmission substrate is sandwiched between two exterior dielectric substrates, each coated on one side with a metallic layer. The three substrates are laminated together. Through-holes are drilled into the lamination and its interior substrate, at known locations to intersect the said ports. The copper exteriors of each board are etched to identify two contact pad lands on each side. Plated-thru holes are created to connect to each of the ports.
