Abstract: The invention relates to an improvement in an endless track belt of the type comprising, a body made of an elastomeric material, an outer surface for contact with the ground and an inner surface provided with lugs or openings for engagement with the driving system and at least one endless pathway having a sliding surface contacting a corresponding slide rail of a slide rail suspension. This pathway is devoid of the lugs or openings for engagement with the driving system. The endless sliding surface is provided with a plurality of slide clips that are spaced apart from each other by a segment of the endless sliding surface. This segment is divided in at least a first and a second distinct part. The first part is made of elastomeric material and the second part defines at least one cavity through the body. The improvement is characterized in that the cavity through the body is to allow the introduction of snow between the slide rail and the first part and in that the first part is of such size that friction with the slide rail will generate heat in a sufficient amount to melt the snow and maintain a lubricating film of water therebetween. Such track belts are of a reduced weight but as efficient as common track belts.

Patent CA-2138966-C (CA)
Inventor: PETTERSON BART
IPC: F24F11/75
Filed: 1993-06-21
Granted: 2004-05-18
Abstract: A ceiling vent (10) diffuses air from a heating or cooling system in a laminar flow into a room for optimum dispersion in the room. Inlet air strikes a hinged vane (26) within the vent. The vane deflects the air in a narrowing air way along a continuous concave curvature and extending all the way to the outlet opening of the vent.  The vane responds to the force of air flow to narrow or enlarge the air way and, thus, regulate the velocity of air exiting the vent. A curved air catch (32) associated with the vane directs the outflow of air and also laterally disperses air within the vent.  The vent maintains a relatively constant velocity and diffusion of air into a room despite variable flow rates from the source of air.

Patent CA-2149152-C (CA)
Inventor: CHEN CHIH-MING
IPC: A61K9/20
Filed: 1993-11-02
Granted: 2003-09-30
Abstract: Unit dosage form for delivering drugs into the body in a series of sequential, pulsatile releasing events employs conventional pharmaceutical equipment and processes for optimum economy, reliability, and bioavailability.  The system can be used with drugs which cannot be released by diffusion through a porous coating, such as water insoluble drugs.  A plurality of populations of pellets is provided within a unit dosage form such as a capsule (8) or tablet. The pellets are composed of a core containing the drug (3) and a swelling agent (4) which expands in volume when exposed to water.  The core is enclosed within a membrane or coating which is permeable to water.  The membrane is composed of a water insoluble and permeable film forming polymer, a water soluble film forming polymer (11) and a permeability reducing agent (14).  When the unit dose releases the pellets into the digestive tract, water diffuses through the coating and into the core.  As water is taken up by the swelling agent, the core expands, exerting force on the coating until it bursts, releasing the drug.  The permeability reducing agent reduces the rate at which water reaches the swelling agent, thereby delaying release time.  The water soluble polymer dissolves, weakening the coating so that it bursts sooner.  By varying the proportions of the three coating ingredients and/or coating thickness from one pellet population to another, the release timing of the pellets can be very effectively controlled.

Abstract: A sintered hardmetal (cemented tungsten carbide) product has a core made of a first grade of cobalt or nickel bonded cemented tungsten carbide with a surface layer of a second grade of distinctively different cobalt or nickel bonded cemented tungsten carbide. The first grade, or core, is generally a relatively tough (impact resistant or shock resistant) grade of cobalt or nickel bonded hardmetal while the surface layer is a relatively hard (wear resistant) grade of cobalt or nickel bonded hardmetal. The surface layer may, however, be designed to provide corrosion resistance or crater resistance to the article. If desired, multiple layers can be provided with gradient layers included between the core and surface layer. Typical uses of such layered composite carbide articles are as tool materials such as cutting tools or cutting tool inserts, mining tools or wear parts of any design typically manufactured in the cemented carbide industry.

Granted: 2004-08-24
Abstract: A method for fabricating a sub-micron structure of etch-resistant metal/semiconductor compound on a substrate of semiconductor material comprises the step of depositing onto the substrate a layer of metal capable of reacting with the semiconductor material to form etch-resistant metal/semiconductor compound, and the step of producing a focused electron beam. The focused electron beam is applied to the layer of metal to locally heat the metal and semiconductor material and cause diffusion of the metal and semiconductor material in each other to form etch-resistant metal/semiconductor compound. The focused electron beam is displaced onto the layer of metal to form the structure of etch-resistant metal/semiconductor compound. Finally, the layer of metal is wet etched to leave on the substrate only the structure of metal/semiconductor compound. Following wet etching of the layer of metal, an oxygen plasma etch can be conducted to remove a carbon deposit formed at the surface of the structure of etch-resistant metal/semiconductor compound.      Also, the substrate may be subsequently etched to remove a thin layer of metal rich semiconductor material formed at the surface of the substrate by reaction, at room temperature, of the metal and semiconductor material with each other.
