Title: Method for recovery of carbon and combinations of hydrocarbons from polymers, preferably in the form of disposed tyres, by pyrolysis in a pyrolysis reactor
Inventor: ERSHAG BENGT-STURE
IPC: B01D5/00
Filed: 1999-08-20
Granted: 2002-06-27
Abstract: The invention relates to a method for the recovery of carbon and combinations of hydrocarbons from discarded tyres or similar polymeric material by pyrolysis, using a reactor (3) in which the material is placed in a preferably largely fragmented condition, whereby the material is heated to pyrolysis temperature by the recirculation of previously formed and heated pyrolysis gas which is led through the material and where the pyrolysis gas obtained in this way is brought to condense to condensable products in a condenser (8) connected to the reactor. In order to improve the possibilities of control of the process of pyrolysis, a reactor is used with an inlet (6) and an outlet (7) so that a gas can be led through the reactor (3) passing over the polymeric material which is placed in it, whereby at least a part of the pyrolysis gas which does not condense in the condenser (8) is heated to a predetermined temperature and is led by recirculation in a circuit through the reactor for heating the polymeric material placed in it.

Title: Separation of active complexes
Inventor: SKOZA FRANCIS C JR
IPC: C12N15/87
Filed: 1996-05-28
Granted: 2000-01-06
Abstract: The invention separates defined, active complexes by a characteristic from Defined, active complexes that share a particular physicochemical characteristic such as density, surface charge or particle size are separated from complexes formed by the association of a polynucleotide with a transfecting component that increases transfection activity, such as a lipid, cationic lipid, liposome, peptide, cationic peptide, dendrimer or polycation. In a preferred embodiment, polynucleotide-transfecting component complexes are ultracentrifuged to resolve one or more bands corresponding to complexes having a specific polynucleotide-transfecting component interaction. Polynucleotide complexes having a cationic liposome transfecting component resolve into two primary bands corresponding to complexes formed either under excess lipid conditions or under excess polynucleotide conditions. In an alternate embodiment, polynucleotide-transfecting component complexes are resolved using cross-flow electrophoresis to identify complexes having specific interactions and to separate them from excess initial components.

In another embodiment (FIG. 4), an elongate raised bead (8) is formed longitudinally of the anticipated line of bending of the connection (6). In a still further embodiment (FIGS. 5 to 7), an elongate raised bead (9) extends transversely of the anticipated line of bending of the connection (6) and to either side of said line. In a still further embodiment (FIG. 9), an abutment (11) is secured or formed on the inner face of the can end (1) adjacent to the anticipated line of bending about the connection (6). In each of the embodiments, the bending radius of the tab (4) about the connection (6) is substantially increased to effectively prevent fracture of the tab (4) occurring.

Title: Angioplasty light guide catheter
IPC: A61M29/02
Filed: 1991-03-04
Granted: 1993-01-28
Abstract: The angioplasty light guide catheter has a dilatation balloon (1) which is to be introduced into the vessel to be treated. The inside of the balloon is connected via a shaft to a suction and forcing pump and can therefore be regulated precisely in diameter. Light guides (6) extend over the entire length of the shaft and are coupled to a laser device via a connection piece at the proximal end of the catheter. At the distal end the light guides are embedded in the wall of the dilatation balloon (1). For stenosis ablation using laser light energy, the outlet points of the light guides can be moved radially outwards and inwards by changing the pressure in the dilatation balloon. The distance of the outlet points (6a) from the centre line of the balloon is thus a function of the pressure of the balloon fluid. This distance can thus be altered and controlled in a simple manner.

Title: Apparatus and method for cleaning and finishing
Inventor: SEVIGNY CLAUDE
IPC: B24D7/04
Filed: 1998-05-08
Granted: 2001-05-03
Abstract: Apparatus and method for both cleaning and polishing work surfaces such as automotive panels using a single combination pad. In one embodiment, a support holds a circular replaceable, disposable cleaning/polishing pad on a powered polishing tool for rotation about the pad's central axis. The illustrated pad is made of compressible/expandable material such as foam. The pad has front and rear recesses that define concentric radially outer and inner sections. The inner section is thinner and has a forward cleaning surface. The outer section normally protrudes forwardly of the cleaning surface so that when it is first brought into engagement with a work surface, the cleaning surface does not engage the work surface. A pressure-applying backup plate of a firm material such as neoprene has a forwardly displaced inner portion that is received in the pad rear recess for applying firm pressure to the pad cleaning surface. The plate has an outer portion for applying pressure to the outer pad section. In operation, the pad is positioned at the work surface and then rotated. The backup plate applies sufficient force to initially axially compress the outer pad section and position the cleaning surface at the work surface. Further force acts through the backup plate inner portion to apply firm distributed cleaning action by the cleaning surface against the work surface to remove the amount of material desired. Then the axial force is reduced to allow the pad outer section to expand and move the cleaning element out of engagement with the work surface. This allows the rotating foam outer section to be used to engage and polish the cleaned area of the work surface.
