Title: A surface covering tile
Inventor: BLATZ WARREN J
IPC: E04F15/10
Filed: 1995-11-14
Abstract: A surface covering tile is disclosed having integral connecting elements about its edges to enable hinged interconnection between adjacent-like tiles. The connecting elements are longitudinally arranged about the peripheral edges of the tile and comprise semi-cylindrical curved female elements, protruding tongue elements and semi-cylindrical bar-like male elements. The elements are arranged such that the female and tongue elements cooperate to engage with the male elements of adjacent tiles. The tile is further adapted to receive a surface covering such as a carpet or mat, preferably an air permeable covering which will permit air to pass through apertures in the surface of the tile to the ground below.
Patent CA-2163234-A1 (CA)
Title: Inhibition of proliferation of vascular smooth muscle cell
Inventor: DZAU VICTOR J
IPC: A61K38/00
Filed: 1994-05-18
Abstract: This invention encompasses a method for inhibiting vascular cellular activity of cells associated with vascular lesion formation in mammals which involves administering an effective dosage of at least one antisense sequence to at least one gene expressing a cyclin or a cyclin dependent kinase which inhibits the expression of the gene. More particularly, the invention involves administering antisense sequences which inhibit the expression of cyclin A, B1, B2, C, D1, D2, D3, E or cyclin X (p46) and cyclin dependent kinase cdc2, cdk2, cdk4 or cdk5. It is preferable to use two antisense sequences each from a different cyclin or cyclin dependent kinase. The cyclin or cyclin depending kinase dosage is preferably administered in combination with proliferating cell nuclear antigen (PCNA). Antisense methods and compositions direct to inhibiting the expression of growth factors such as TGF-.beta.1, TGF, bFGF, PDGF are also contemplated by the present invention. The antisense sequences are incorporated into liposomes, particularly liposomes containing HVJ and which are directly administered intraluminally, intramurally or periadventitiously.  While the methods of this invention are useful in treating a broad spectrum of vascular lesions such as lesions in the carotid femural and renal arteries, particularly lesions resulting from renal dialysis fistulas. The invention is particularly useful in treating vascular lesions associated with coronary artery angioplasty.

Patent CA-2183781-A1 (CA)
Inventor: CONBOY JOHN S
IPC: C09J7/20
Filed: 1995-03-03
Abstract: A plastic wall board tape (10) having a raised center section (11) and outwardly extending wing areas which have a coating of fibers (13) adhered to both sides. The raised center (11) of the tape is weakened at the top to cause the tape (10) to crease in a straight line when it is folded at an inside or outside corner to define a straight edge at the corner joint. The combination of the rigid water impervious tape (10) and the fibers (13) allows the tape (10) to be applied over imperfectly fitted wall board joints with large imperfections because the fibers (13) will achieve a mechanical bond with the wall board compound or other joint materials, allowing a slow cure, and the tape (10) will not be softened by the compound. When used on an inside comer, the tape (10) can be finished merely by striking the outer edge with compound as the top surface is a finish surface and requires paint only. The tape (10) can have triangular cutouts in the wings and removable end strips to facilitate taping of curved corner joints.

Title: Method of reducing odors in animal confinement buildings and lots
Inventor: HUGHES JEREMIAH F
IPC: A23K20/20
Filed: 1996-09-06
Abstract: A method for reducing odors in animal confinement buildings and feedlots includes the initial step of mixing natural zeolite with animal feed and feeding the animal feed to animals to prevent odors produced by the animals. Preferably, natural powdered zeolite is added to animal feed in a ratio of approximately 20 pounds per ton of animal feed. Zeolite in granular form is preferably mixed with a sufficient amount of water to prevent dust, and then applied to the ground within the animal confinement building, to eliminate animal manure odors. The granular zeolite is preferably a 70% mixture of zeolite to 30% filler for application to the confinement building floor, and the ratio of zeolite to water is approximately 20-1.  Zeolite is also applied directly to the ground in a feedlot which surrounds the confinement building, to further eliminate odors produced by manure in the feedlot.

Title: Low pressure gaseous fuel pressure regulator for turbocharged gaseous fuel engines
Inventor: KARINIEMI DEAN ALBERT
IPC: F02M21/02
Filed: 1997-02-13
Abstract: A gaseous fuel pressure regulator includes a moveable diaphragm that subdivides the regulator housing into a pressurized gas chamber and a reference pressure control chamber. A coil spring in the control chamber exerts a control force on the diaphragm in opposition to the gaseous fuel pressure that is to be regulated. The diaphragm is connected to a lever that carries a poppet valve element associated with a gaseous fuel inlet port supplying unregulated pressurized gaseous fuel to the gas chamber. An arcuate baffle structure partially surrounds the inlet port, such that gaseous fuel flow is directed from the inlet port toward the gas chamber central axis, instead of flowing directly from the inlet port to a nearby outlet port. Tolerance variations on the manufactured components are overcome by the provision of a spring force adjustment structure, that can comprise a hollow tower carried on the cover of the regulator, and adjustment screw is mounted in the tower to adjust the position of a cup-shaped spring seat. Adjustment of the screw can be used to maintain a desired gaseous fuel output pressure, in spite of tolerance stack-up that might otherwise adversely affect performance of the regulator.
