Patent CA-2135954-A1 (CA)
Title: Fuel vapor vent assembly with liquid trap
Inventor: GIMBY DAVID R
IPC: B60K15/035
Filed: 1994-11-16
Abstract: A fuel vapor vent assembly with liquid trap is incorporated in a vent valve mounted on a motor vehicle fuel tank.   The vent valve operates to vent the fuel tank through a vertically  oriented orifice in the vent assembly when the valve is in a normal upright position and closes the orifice when the fuel tank together with the valve is tipped to a significant degree from this position.  An elevated liquid trap is provided in the vent assembly at the outlet of the orifice that traps liquid from the venting fuel vapor while permitting venting to continue therethrough and then drains the trapped liquid back past the valve into the tank when the pressure in the latter is relieved.   An insert mounted in the valve body is adapted to define both the orifice and liquid trap.

Title: Psychometric testing
Inventor: BAUM MICHAEL
IPC: G09B23/28
Filed: 1993-07-12
Abstract: In a method for measuring or monitoring throughout any predetermined period the percentage value rating of a self-assessed variable in relation to one or more test individuals, for example each individual's feeling of well-being or quality of life rating during the course of medical treatment, each test individual is supplied with a record card (10) that has a black surface (12) overprinted with a number of separate light silver coloured squares (14) composed of opaque material that can be removed selectively by scraping or scratching. At the end of each day, the test individual scratches away at least part of the opaque silver material of a relevant square (14) to expose the darker underlying area to an extent that is considered to be visually representative of how well or unwell that individual has felt on average during that day.  The daily results are recorded on the silver coloured recording squares in a predetermined order and testing is continued for a predetermined period, e.g. 28 days. At the end of that time, the card (10) is processed using an image scanning device (25) connected to a computer system that processes the digitised data generated to measure the proportion or percentage amount of each silver recording square that has been removed, the output being provided in a form selectable by the user. The system described may be adapted for measuring or monitoring other intangible variables or characteristics that are quantifiable in terms of a percentage value rating determined by personal assessment of a test individual.

Title: Beverage Container Valve
Inventor: FEER DAVID L
IPC: B65D47/30
Filed: 1995-06-16
Abstract: A bleeder valve venting system includes a bleeder valve that is provided, and adapted to mount through a lid aperture, the valve having an enlarged upper cap portion, a cylindrical intermediate portion which extends through the lid aperture, and a semi-spherical lower working portion. A central axial through-bore extends downward through the cap and intermediate portions, and a slit is provided to extend upward into the lower valve portion and communicate with the through-bore. The lid aperture is sized to admit the valve with interference, whereby establishing a liquid tight seal between the valve body and portions of the lid defining the aperture. The valve is composed of resilient material and the slit is dimensioned to open to a width sufficient to admit air when a pressure differential exists between the inside and outside of the container. As the slit opens, the lower working valve portion is compressed against inside surfaces of the lid, and, upon equalization in air pressure, the working valve portion reacts to force the slit closed.

Title: Two-phase tooth implant
Inventor: MOSER WALTER
IPC: A61C8/00
Filed: 1995-10-16
Abstract: Mechanical joining of a two-phase tooth implant, consisting of two components which are joined by means of a conical pin (11) projecting into a conical sleeve (7), the cone pairing being realized within the self-locking region and the cone pin being penetrated by a centrally aligned, tension screw reduced diameter which tensions the pair of cones against each other. The design permits the two implant components in a two-phase tooth implant to be steplessly positioned in the circumferential direction and to be joined in an anti-rotation, gap-free joint. The required degree of miniaturisation, with a sufficient component strength, is achieved through the use of a cone combination in the self-locking region and through a of the tension screw in the region of the cone joint. By these means, the mechanical, aesthetic and hygienic requirements for a two-phase tooth implant are better fulfilled than in the case of the known designs.

Title: Ballast broom with auger and method
Inventor: HOLLEY JOHN D
IPC: E01B27/04
Filed: 1996-07-16
Abstract: A railroad ballast broom vehicle uses a double or split auger to move ballast received from a rotary core broom. The auger has various features to minimize the risk of it jamming on ballast which it moves to the field side of rails of the railroad bed which is being swept. Flex plates are used to mount broom drive hydraulic motors to minimize or avoid problems which might otherwise be caused by slight misalignments in the motors and the rotary core of the broom. A dust control system is used to minimize escape of dust from operation of the vehicle. A method of using the vehicle advantageously uses only a single pass of the vehicle over a given section of road bed in need of sweeping.

Patent CA-2186372-A1 (CA)
Title: Improved blood contact surfaces using extracellular matrix synthesized in vitro
Inventor: BRUCHMAN WILLIAM CARL
IPC: A61F2/06
Filed: 1995-04-28
Abstract: This invention is directed to improved blood contact devices such as vascular pros-theses rendered substantially nonthrombogenic through addition of a preserved layer of extra-cellular subendothelial matrix. The preserved subendothelial matrix layer, which serves as the blood interface of the device, is analogous to the subendothelial matrix layer beneath the endothelium of native vascular surfaces. The device consists of a permanent synthetic base material, preferably porous expanded polyte-trafluorothylene, on which this biologic layer of subendothelial matrix is grown in situ. The biologic layer is produced using in vitro tis-sue culture methods whereby living cells syn-thesize and deposit extracellular matrix com-ponents, after which the cells are killed and or removed and the subendothelial matrix layer preserved before implantation. A key aspect of this invention is that no living cells are present in the final configuration, so that the likelihood of recipient immunological response is mini-mized. This invention results in vascular pros-theses that are particularly useful for arterial bypass requiring a diameter of 6 mm or less.
