Title: Apparatus and method for sealing the corners of insulated glass assemblies
Inventor: LAFOND LUC
IPC: C03C27/06
Filed: 1998-06-10
Abstract: The present invention relates to an apparatus and method for injecting sealant material into the comers of an insulated glass assembly (50) suitable for use in manual and automated production. It has been found that significant saving in both time and material can be achieved by only sealing the comers of the assembly, particularly using the automated method and apparatus.      The apparatus includes a pair of wiper blocks (14, 16) each having a surface (15, 17) for abutting an edge of a glass assembly (50) arranged in substantially perpendicular configuration to each other, adapted for converging and diverging reciprocal movement from an adjoining position for molding a square comer to a separated position for wiping smooth the surface for the injected sealant material. A nozzle (12) is positioned between the wiper blocks (14, 16) for injecting sealant material into the comer area and retracting in concert with the converging movement of the wiper blocks (14, 16). The method according to the present invention includes confining a comer area to be filled with sealant material, injecting sealant material into the corner area, molding the injected sealant into a substantially square comer, and wiping smooth the surface of the injected sealant.

Patent CA-2303084-A1 (CA)
Title: Needleless valve
Inventor: DOYLE MARK CHRISTOPHER
IPC: A61M39/00
Filed: 1998-08-31
Abstract: A needleless valve is described which avoids the suctioning problems of the prior needleless devices upon deactivation and which preferably provides a positive self-purging effect, The valve is self-purging at the end of an administration cycle, avoiding clogging of attached catheters or other devices, and ensures that substantially all of liquid received into the valve is delivered to the receiver. The valve is also extremely simple in design and easy to construct and assemble, since it consists of only three pieces. The valve has a base with a connector for fluid communication attachment to tubing or other device, a solid elongated fluid channeling rod, and an internal fluid flow conduit; a flexible hollow expandable and contractible plug fitting over and moveable along the rod; and a tubular housing fitting over the plug and attached to the base. When the valve is activated by insertion of a nozzle of a fluid source, the rod and plug wall cooperate so that as the plug retracts along the rod, it is stretched and its interior expanded. Upon deactivation, the plug contracts, the interior volume decreases, and the resiling plug wall forces residual fluid within the valve to be expelled through the outlet, purging the residual fluid from the valve. No negative pressure is formed, so no suctioning of blood or other fluid from a patient or receiver occurs.

Inventor: WALLACE DOUGLAS M
IPC: E03F1/00
Filed: 2000-04-17
Abstract: A buffer box for use in a vacuum drainage system. The buffer box defines a reservoir of known effective size which provides substantially consistently sized slugs of liquid which may be efficiently pulled up a vertical lift. The buffer box includes an outlet and an air intake orifice which may be sized relative to one another so that only liquid from the reservoir is evacuated. The outlet has an upper edge which may be spaced from a base portion of the buffer box at a height which optimizes liquid velocity out of the box and defines a level above which only water is evacuated from the reservoir.

Title: Multiply-substituted protease variants
Inventor: BAECK ANDRE C
IPC: C11D7/42
Filed: 1998-10-23
Abstract: Novel protease variants derived from the DNA sequences of naturally-occurring or recombinant non-human proteases are disclosed. The variant proteases, in general, are obtained by in vitro modification of a precursor DNA sequence encoding the naturally-occurring or recombinant protease to generate the substitution of a plurality of amino acid residues in the amino acid sequence of a precursor protease. Such variant proteases have properties which are different from those of the precursor protease, such as altered wash performance. The substituted amino acid residue correspond to positions 62, 212, 230, 232, 252 and 257 of Bacillus amyloliquefaciens subtilisin.

Title: Endolumenal aortic isolation assembly and method
Inventor: COLEMAN RONALD
IPC: A61F2/958
Filed: 1998-11-20
Abstract: A medical device assembly is adapted to isolate the heart from systemic circulation while perfusing oxygenated blood to the systemic arterial circulation during a minimally invasive bypass procedure. The assembly includes an arterial catheter with an external shunt valve which forms an anchor to secure the distal end portion within the aortic arch and which also forms a funnel which shunts antegrade aortic blood flow from the aortic root, into a distal flow port and through an internal flow lumen in the catheter, out an intermediate flow port along the catheter proximally of the anchor, and into the systemic arterial circulation. A distal internal valve located within the internal flow lumen between the distal and intermediate flow ports selectively occludes the shunted antegrade aortic blood flow between the distal flow port and the intermediate flow port, thereby isolating the left ventricle from the systemic arterial circulation wherein oxygenated blood may then flow from a cardiopulmonary bypass pump, distally through the internal flow lumen, and out the intermediate port. The assembly also includes a venous catheter which aspirates venous blood from the vena cavae and into the cardiopulmonary bypass pump while substantially isolating the right heart chambers from the vena cavae and without circumferentially engaging the internal walls of the vena cavae. A  medical device system is also provided with an arterial catheter having an elongate body with a distal end portion that includes a flow lumen extending between distal and proximal ports and also an aorta isolation assembly located between the distal and proximal ports. The aorta isolation assembly includes distal and proximal portions that are separated by an isolation region and are adjustable to extended positions which are adapted to circumferentially engage the aortic wall. When the intermediate region is positioned along a proximal anastomosis site of an aorta, the distal and proximal protions may be adjusted to their extended positions to engage the aortic wall on upstream and downstream sides of the proximal anastomosis site. Blood flowing within the aorta is thereby isolated from the proximal anastomosis site along the intermediate region and is shunted from an upstream region of the aorta, through the distal port into the flow lumen, proximally along the flow lumen, out from the flow lumen through the proximal port, and into a downstream region of the aorta. A combination arterial catheter system includes the internal valve and the aorta isolation assemblies described, and may be used to selectively perform either a "stopped heart" cardiac bypass procedure or a "beating heart" coronary artery bypass graft procedure.

Title: Subway movie/entertainment medium
Inventor: WALKER ROB
IPC: G09F13/02
Filed: 2000-07-06
Abstract: This invention relates to an apparatus for displaying a collection of stationary images as a motion picture to passengers travelling in a vehicle along a pathway. The train moves at a known speed and known distance from the wall of the pathway in the vicinity of the images. The apparatus comprises a series of image set in mountings along the pathway and stroboscopic lighting for each image. The images, placed in parallel along the walls of the pathway of the vehicle, are adapted in number, size, and spacing for a vehicle travelling at the known speed and at the known distance from one or both walls of the pathway such as to maintain an approximate constant viewing rate and perspective size of the images. The invention includes mounting mechanisms for the images to position each image vertically and at a constant distance from the train regardless of unevenness in wall contour. Glare due to interior lighting in the vehicle is reduced or eliminated by selecting the appropriate illumination intensity for stroboscopic lighting.
