Patent CA-2159082-A1 (CA)
Title: Pressure-tight sluice
Inventor: HIORTH HANS
IPC: B65G53/46
Filed: 1994-03-25
Abstract: A pressure-tight sluice for feeding powder material e.g. from a silo to a pressure container is able to establish a substantial pressure different with a minimum consumption of air. This is achieved by a novel sluice housing (1, 3) with a superelliptical torus shape and with adapted inlet (5) and outlet (7) which provide a favourable powder flow and efficiency of utilization. Further, the sluice has an effective and self-adjusting compressed-air controlled sealing system which enables substantially larger pressure difference as a consequence of efficient sealing (17) between rotor and housing (1, 3). By means of a pressure equilization line (45) between the return side and powder side of the sluice, a further saving of air is achieved.

Patent CA-2163331-A1 (CA)
Inventor: THOMAS DENNIS ALBERT
IPC: B29D5/00
Filed: 1994-05-09
Abstract: The invention is a refastenable mechanical fastening system (20), made of free formed prongs (22) joined to a substrate (24). The prongs (22) taper and are nonperpendicularly oriented relative to the plane of the substrate (24). The prongs (22) also have an azimuthal angle relative to the machine direction of the substrate. Each prong has an engaging means (30) projecting laterally from the periphery of the prong (22). The free formed prongs are manufactured by the process of depositing liquid material onto a moving substrate to form the base of the prong, stretching the liquid material in a direction parallel to the plane of the substrate, severing the stretched material to form the distal end and engaging means of the prong and allowing the prong to azimuthally angle. The advantageous usage of the fastening system in an article of manufacture, such as a disposable absorbent article specifically a diaper, is also disclosed.
Patent CA-2164207-A1 (CA)
Title: Multiple capillary biochemical analyzer
Inventor: DOVICHI NORMAN J
IPC: G01N30/46
Filed: 1994-06-02
Abstract: A multiple capillary analyzer allows detection of light from multiple capillaries with a reduced number of interfaces through which light must pass in detecting light emitted from a sample being analyzed, using a modified sheath flow cuvette. A linear or rectangular array of capillaries is introduced into a rectangular flow chamber. Sheath fluid draws individual sample streams through the cuvette. The capillaries are closely and evenly spaced and held by a transparent retainer in a fixed position in relation to an optical detection system. Collimated sample excitation radiation is applied simultaneously across the ends of the capillaries in the retainer. Light emitted from the excited sample is detected by the optical detection system. The retainer is provided by a transparent chamber having inward slanting end walls. The capillaries are wedged into the chamber. One sideways dimension of the chamber is equal to the diameter of the capillaries and one end to end dimension varies from, at the top of the chamber, slightly greater than the sum of the diameters of the capillaries to, at the bottom of the chamber, slightly smaller than the sum of the diameters of the capillaries. The optical system utilizes optic fibres to deliver light to individual photodetectors, one for each capillary tube. A filter or wavelength divisicn demultiplexer may be used for isolating fluorescence at particular bands.

Abstract: A system and method of catheterization, includes a needle (22), a "Y" chamber (27), a syringe or other chamber (46), a dilator, a sheath (80), a protective sleeve (92), and a shock sheath (100). This introduces a comprehensive, uniform and universal approach to catheterization. Discriminatory methods of treatment using the invention are described. Particular attention has been paid to current problems in catheterization and the prevention of transmission of communicable diseases from patient to practitioner and vice versa (e.g., the risk of contracting the HIV virus is substantially reduced using this system and method). The discriminatory treatment of diseases, in particular, cancer, is now rapid, safe and in some instances, novel. The invention makes possible substantial reductions in the cost of health care while improving the efficiency of diagnosis and treatment. The invention allows the practitioner to perform simultaneous diagnosis and treatment of diseases using the same procedure, regardless of their location in or on the body. The number and duration of hospitalization is minimized, and the quality of life and length of survival for the patient is improved.

Patent CA-2182544-A1 (CA)
Inventor: FANDRICH HELMUT EDWARD
IPC: B66C1/58
Filed: 1996-08-01
Abstract: The grapple comprises left and right frame members hinged together at a main hinge, and left and right arms hinged together at the main hinge and having outer portions cooperating with a supporting cable. The grapple has left and right fingers to grasp a load, each finger being hinged to a respective frame member and connected to a respective arm. The grapple also includes a latching mechanism which cooperates with the fingers and arms to partially control angular relationship between the finger and the respective arm for actuation of the grapple. The latching mechanism is remotely controllable by an operator to release the load, and then requires re-setting to enable the grapple to grasp a subsequent load. The grapple is supported by a single cable extending from the arms to a helicopter and, prior to grasping a load, is positioned on the ground to straddle the load. When the grapple is on the ground, the cable slackens, and the latching mechanism is automatically re-set, using weight of the grapple only, and thus does not require manual intervention by a ground operator for re-setting. As the grapple is raised, the arms move upwardly and the fingers move inwardly to grasp the load, and the load is held securely until released by unlocking the latching. Weight of the load assists in forcing the fingers open which occurs at a controlled rate to reduce shock load on the helicopter.

Abstract: Presently, men's shaving cartridges come in one regular size with two blades on each. However, this size is not practical for shaving the delicate and parts of a man's face, such as the mustache and sideburn regions. Thus, in this proposed invention the shaving cartridges will have two different sizes of shaving cartridges, each with one or two blades, attached to a connecting middle cartridge at an inclined angle to facilitate shaving. Further, the handle used to attach the cartridges will no longer be inclined at the attachment edge and use the traditional methods of attachment. The improved straight handle will be placed and fixed within each new cartridge's middle connecting cartridge. using a rotation type of installment procedure.
