Title: Seal sustaining hardware for caskets
Inventor: ROJDEV ILIJA
IPC: A61G17/04
Filed: 1995-03-14
Abstract: Casket hardware comprises a corrosive trim plate adapted to be secured to an outer surface of a wall or a casket, an arm adapted to support a casket handlebar and having a bolt connected thereto, the bolt being adapted to pass through the plate and the casket wall, a nut threadably engaging the bolt interior of the casket, a seal surrounding the bolt between the nut and the inner surface of the casket wall and a non-corrosive compressive load carrying member between the casket wall and the arm for creating tension in the bolt as the nut is tightened against the seal. When the corrosive trim plate corrodes and falls away from between the casket wall and the arm the non-corrosive compressive load carrying member maintains the bolt in tension thereby maintaining the seal in compression between the nut and the casket wall inner surface.

Title: Separating solutes from solutions
Inventor: SMART NEIL GRAHAM
IPC: B01D11/04
Filed: 1995-07-07
Abstract: A method of separating a solute from a supercritical fluid which includes reducing the pressure of the supercritical fluid and is characterised in that the supercritical fluid and solute are mixed with another fluid, eg an inorganic or organic solvent under pressure, to cause a partial reduction in the pressure of the supercritical fluid followed by reduction of the pressure of the fluid mixture comprising the supercritical fluid and said other fluid.  The fluid mixture pressure reduction may occur in the collection device.  Such a device may have a collection solvent already present therein. The said other fluid used partially to depressurise the supercritical fluid may act as a collection solvent in a collection device.  The collection device may include one or more collection vessels or alternatively a solid phase trap or a packed column for the purpose of trapping and collecting the solute.

Patent CA-2166350-A1 (CA)
Inventor: WEINSTEIN VALERY G
IPC: B27F7/09
Filed: 1995-12-29
Abstract: A combustion-powered, fastener-driving tool comprises a structure defining a combustion chamber and defining a driving piston cylinder, which has a wall and defines an axis.  A nosepiece is mounted to said structure and communicates with the driving piston cylinder.  A driving piston mounting a driving member is arranged to be axially driven within the wall of the driving piston cylinder upon combustion of a fuel in the combustion chamber, so as to drive the driving member from an uppermost position wherein the driving member is retracted from the nosepiece into a lowermost position wherein the driving member is extended into the nosepiece.  A combusted gases-actuated mechanism is employed for feeding fasteners from a collated strip of fasteners individually and successively into the nosepiece.  Combusted gases are diverted from the driving piston cylinder so as to actuate the feeding mechanism when the driving piston is driven.  Combusted gases are taken in through the wall of the driving piston cylinder, at a location between the uppermost position of the driving piston and the position of the driving piston when combusted gases are exhausted through one or more ports in the wall of the driving piston cylinder.

Abstract: A method and device for detecting myoglobin amongst other mammalian peroxidatively active substances like  hemoglobin  is  disclosed.    Since  the  existing peroxidase-sensitive  components  do  not  discriminate between myoglobin and hemoglobin, the present method and device provide discrimination by including a filtration step  or  component  which  separates  myoglobin  from hemoglobin on the basis of their difference in molecular weights.  The present method and device offer a quick and easy detection of myoglobin, especially in urine, and  may  conveniently  use  existing  reagents  and apparatus.

Patent CA-2177775-A1 (CA)
Title: Cleaner for a submerged surface
Inventor: DURIGON DUILIO
IPC: E04H4/16
Filed: 1996-05-30
Abstract: A swimming pool cleaner has a body which defines a liquid inlet and an outlet which is connected via a hose to a source of suction. A throat between the inlet and the outlet defines a region of reduced cross-sectional area, causing a zone of low pressure as liquid flows through the throat. A valve element in the form of a cylindrical shuttle is located in a bore which intersects the throat, and which can move into the throat to block it intermittently. An auxiliary suction passage connects the rear of the bore to the outlet, so that suction is applied to both ends of the shuttle, causing it to reciprocate in the bore, periodically obstructing the flow of liquid through the throat. This causes the cleaner to move across the submerged surface. The design of the cleaner makes it resistant to jamming due to objects being trapped between the valve element and the throat.

Title: Drive-rod type drive mechanism
Inventor: ZEUS CHRISTIAN
IPC: E05C9/00
Filed: 1996-08-16
Abstract: A drive type operating mechanism for locking gates, windows, double-wing doors and the like includes push rods which are movable longitudinally in opposite directions to effect locking of the upper and lower ends of the door with the surrounding framework.  The mechanism is connected for actuation by a lever handle through an arrangement of follower elements that are slidable supported in a lock case.  A nut sleeve follower which is rotatable by the lever handle has one claw which cooperates with a groove in one longitudinally movable follower, and a second claw which cooperates with a transversely slidable intermediate follower which in turn cooperates with a groove in the second longitudinal follower, this arrangement ensuring that upon rotation of the handle the followers (and hence the locking bolts) move in opposite directions.  A lock mechanism ensures that the longitudinally movable followers are not inadvertently moved from their end limiting positions.
Patent CA-2185403-A1 (CA)
Title: Methods for Reducing Inhibition of Nucleic Acid Amplification Reactions
Inventor: WOODARD DANIEL L
IPC: C12Q1/68
Filed: 1996-09-12
Abstract: It has been found that certain glycoproteins, particularly mucins, are inhibitors of nucleic acid amplification reactions and that inhibition of the amplification reaction is associated with partial degradation of the carbohydrate chain. Partial degradation of the carbohydrate of a non-inhibitory glycoprotein renders it inhibitory, and partial degradation of the carbohydrate of a slightly inhibitory glycoprotein makes it more inhibitory. Sample processing prior to amplification may contribute to partial degradation of the carbohydrate chains of the glycoproteins which are present and increase their inhhibitory effect. In contrast, complete removal of the carbohydrate significantly reduces or completely eliminates the inhibitory effect. Methods for reducing or eliminating glycoprotein-associated inhibition of nucleic acid amplification reactions are also disclosed.

Title: Methods for harvesting adipose tissue containing autologous microvascular endothelial cells
Inventor: HU CAN B
IPC: A61F2/06
Filed: 1995-06-29
Abstract: Disclosed herein are methods for harvesting adipose tissue so as to preserve an increased population of viable microvascular endothelial cells. Adipose tissue containing microvascular endothelial cells is harvested using a collection apparatus incorporating an elongate cannula having apertures with tissue cutting edges. A sub-ambient pressure is applied to a lumen in the cannula to draw the adipose tissue through the aperture where it is then severed using the cutting edge to disrupt the connective adipose matrix. This harvesting provides a cleaner, more homogeneous sample of adipose tissue, thereby increasing the population of viable microvascular endothelial cells obtained through further processing. Rapid and easy methods for the further homogenization of the harvested adipose tissue are also disclosed.
