Patent CA-2060909-A1 (CA)
Title: Rubber-metal bushing and method of producing the same
Inventor: MCLAUGHLIN RONALD J
IPC: B29C65/52
Filed: 1992-02-10
Abstract: ABSTRACT   A rubber-metal bushing includes a seamless inner metal drawn-over-ma?drel ("DOM")tube surrounded by an elastomer cylinder.  A flanged ferrule is press fit into one or both ends of the tube so that the flange engages an end portion of the cylinder.  The bushing is cost reduced by replacing the DOM tube with a seamed tube formed from flat stock.  An adhesive at the tube-ferrule interface maintains the two elements together.

Title: Dna encoding a lipase and a lipase modulator
Inventor: JORGENSEN STEEN T
IPC: C12N15/09
Filed: 1990-07-05
Abstract: A DNA sequence encoding a factor which acts in trans as a modulator of the production of a Pseudomonas cepacia lipase, or encoding an analogue of the lipase modulating factor, will, when present in a host cell which also contains a DNA sequence encoding said lipase, exert a beneficial effect on lipase production.  The lipase modulating factor has this effect even when it or the lipase are expressed from heterologous expression signals or in heterologous cells.

Title: Superelastic formable guidewire
Inventor: RAMAN L VENKATA
IPC: A61B5/00
Filed: 1992-05-20
Abstract: DBB/tac 0414h SUPERELASTIC FORMABLE GUIDEWIRE                Abstract of the Disclosure A guidewire is provided having a malleable segment extending beyond a superelastic tip portion of the guidewire.  Such a configuration provides a guidewire which is resistant to kinking and plastic deformation in the superelastic portion, but which has a distal segment which can be shaped by a physician immediately prior to use in a surgical procedure.  The malleable segment can be attached to the distal end of the superelastic tip portion, or alternatively, can result from a malleable coating on a portion of the superelastic tip, wherein the coating is thick enough to allow the coated portion of the tip to be formed into a desired shape.  The malleable segment can be radiopaque to ease fluoroscopic visualization of the guidewire.  In addition, the entire guidewire located proximally to the malleable segment can be fabricated from a superelastic alloy to provide resistance to kinking and plastic deformation along virtually the entire length of the guidewire.

Title: Measurement of burn depth in skin
Inventor: ANDERSON RICHARD R
IPC: A61F2/10
Filed: 1991-02-22
Abstract: A method for distinguishing between a full thickness and a partial thickness skin burn in a patient having a skin burn. The method includes administering a fluorescent compound, which is excited by infrared light, to the patient to cause the compound to enter one or more capillaries below and adjacent the skin burn. The compound is then excited with infrared light, and the amount of fluorescence of the compound caused by the infrared light detected at the skin burn and at unburned skin adjacent the skin burn. The ratio of fluorescence detected at the skin burn and at the unburned skin is an indication of the thickness of the skin burn, e.g., a ratio of less than 0.4 indicates a full thickness skin burn.

Title: Insulating spacer for creating a thermally insulating bridge
Inventor: GUILLEMET GUY
IPC: B29C48/12
Filed: 1992-12-18
Abstract: An insulating spacer creates a thermally insulating bridge between inner and outer panes of, for example, a multiple pane window unit. The spacer defines an insulated space between the panes and includes a top bridge member, first and second leg members, a bottom bridge member and a channel portion. The top bridge member contacts the inner and outer panes of the window unit. The top bridge member is made of a synthetic resin or composite material and can include openings. The first and second leg members are embedded by crosshead extrusion into the top bridge member. The first and second leg members can be bent into a zig-zag configuration. The bottom bridge member is substantially parallel to the top bridge member. The channel portion is defined by the configuration of the top bridge member, the first and second leg members and the bottom bridge member. In one embodiment, the bottom bridge member is roll-formed from the same piece of material as the first and second leg members. In another embodiment, the bottom bridge member is formed from a material similar to, or the same as, that of the top bridge member. Methods of making the insulating spacer of the present invention also are disclosed.

IPC: E06B9/322
Filed: 1993-02-26
Abstract: ABSTRACT A shade having a closure member able to be moved from one end of an opening to the other between a stored and an extended position for the shade.  There is a drive roller at one end of the shade.  A draw cord extends from the drive roller, through openings in the shade, to a distal end of the shade.  There is an actuator bar attached to the draw cord.

Abstract: A dryer apparatus (10) is disclosed for drying a pressed web (W).  The apparatus (10) includes a plurality of single tier dry-er sections (12, 14) in which successive sections (12, 14) dry alternate sides (16, 18) of the web (W), the web (W) being transferred between successive sections (12, 14) without any open draw of the web (W) such that the web (W) is uniformly dried on both sides (16, 18) thereof while the web (W) is restrained against cross-machine directional shrinkage.  Each of the sections (12, 14) includes a single tier of dryers (20, 22) with an intermediate roll (28) disposed between each adjacent dryer (25).  A dryer felt (30) extends in serpentine configuration around each dryer (24-26) and roll (28) such that the web (W) is disposed between the felt (30) and each dryer (24-26) for drying one side (16) of the web (W).  The felt (30) is also disposed between the roll (28) and the web (W) with the felt (30) in direct contact with an alternate side (18) of the web (W).  The intermediate roll (28) defines a plurality of cir-cumferential grooves (32-37) for diffusing boundary air (38) following the felt (30) that would otherwise tend to lift the web (W) from the felt (30) extending around the roll (28).  The arrangement is such that inherent machine directional shrinkage (MD) of the web (W) during drying thereof inhibits cross-machine directional shrinkage (CD) of the web (W) during movement of the web (W) between successive dryers (12, 14).

Title: Process of preparing sulfate-containing basic solutions of polyaluminumchloride
Inventor: HAAKE GERHARD
IPC: C01F7/786
Filed: 1992-06-24
Abstract: Described is a method of preparing sulphate-containing basic poly(aluminium chloride) solutions. This is done by disinte-grating aluminium-containing salts with hydrochloric acid, filtering off the solid precipitate from the resultant suspension and evaporating down the residue-free solution to crystallize out AlCl3 x 6 H2O.  The AlCl3 x 6 H2O obtained is then decomposed by heating at 150 to 200°C to give a solid basic aluminium chloride which is placed in aqueous sulphuric acid and dis-solved to form Al(OH)xCly(SO~)z. Finally, the basic aluminium chloride sulphate solution obtained is warmed for 1 to 3 hours at 40 to 70°C.
