Abstract: ABSTRACT OF THE DISCLOSURE         A method is provided for the production of 1-(4'-isobutylphenyl)ethanol (IBPE) comprising hydrogenating 4-isobutylacetophenone (IBAP) in the absence of a solvent using as a catalyst a treated activated sponge nickel catalyst, e.g., Raney nickel, obtained by subjecting such a catalyst wetted with a protective liquid composed prepondetantly of water to a washing treatment with an organic washing liquid in which the aqueous protective liquid is substantially soluble and which is substantially soluble in IBAP or IBPE, e.g., a lower alkanol such as methanol, ethanol or isopropanol.  The catalyst optionally may also be washed with IBAP or IBPE after the wash with the organic washing liquid and before being used in the hydrogenation reaction.  The washing treatment results in substantially higher conversions IBAP and increased yields of IBPE with a practical reaction time.

Title: Guiding catheter with controllable distal tip
Inventor: BADGER RODNEY S
IPC: A61M25/00
Filed: 1989-09-26
Granted: 1992-11-03
Abstract: GUIDING CATHETER WITH CONTROLLABLE DISTAL TIP                 ABSTRACT OF THE DISCLOSURE     Guiding catheter and method of using the same in a cardiovascular procedure such as coronary angioplasty.  The catheter has an elongated shaft with a deflectable distal portion.   One lumen extends through the elongated shaft to form a passageway through which a dilatation catheter can be introduced.  A second smaller lumen extends through the shaft to  form  a  passageway  for  a  control  line  which  passes therethrough and   which is connected to the distal tip. Proximal movement of the control line decreases the included angle between the distal portion and the main portion of the shaft.  Pull on the control line also exerts a force on the distal portion of the guiding catheter which transmits a resultant axial force to push the catheter disposed within the first lumen.   Pull  on the control  line also allows  for catheter tip configuration adjustment thereby enabling the catheter to engage a difficult coronary ostium.   In the disclosed embodiments, the distal portion is formed in two sections.   Pulling the control line decreases the included angles between the distal sections and the main sections while the distal portion is positioned within a patient.  The axial force is particularly advantageous with dilatation catheters to aid in directing the distal end thereof across a lesion.

Abstract: ABSTRACT OF THE INVENTION            A  ring  prosthesis  which  provides  different  flexibilities  at various points about the circumference of an associated heart valve.   Specifically,  the annuloplasty ring prosthesis of the invention  includes  a  segmented  body  formed  by  two  or  more segments.    The  individual  segments  form  a  body  which  is substantially circular and shaped proportional to fit about the annulus of the associated heart valve.  The individual segments are held in position with respect to each by a flexible joint. This flexible joint is formed by covering the segments with a flexible material  which fits snugly about the segments.   The cover  is  tied off between  the  adjacent  segments  to further restrain movement of the segments with respect to each other.

Abstract: A method and apparatus for producing a pipe transports first and second sets of chill moulds respectively along first and second endless paths, the chill moulds of each set being so transported one after another, and the endless paths being positioned such that junction faces of the respective chill moulds of the respective sets are positioned against each other in a pipe moulding zone of the endless paths. So positioning the respective chill moulds of the respective sets also defines outer surfaces thereof that are opposite the junction faces and outer surfaces that extend along edges of the junction faces at least generally in the direction of the transporting of the chill moulds. The chill moulds are locked together in the pipe moulding zone with locking surfaces respectively on the outer surfaces of the chill moulds that extend along edges of the junction faces, locking pieces having substantially the same lengths as the chill moulds and U-shaped cross sections, and locking piece transporting means for transporting first and second sets of the locking pieces one after another respectively along two locking-pipe endless paths at the same rate as the chill moulds are transported. The locking-piece endless paths are positioned in the pipe moulding zone such that insides of the U-shapes of the locking pieces engage and lock together the locking surfaces of the chill moulds in the pipe moulding zone. The outer surfaces of the chill moulds that are opposite the junction faces thereof are also pressed while the chill moulds are in the pipe moulding zone for pressing the chill moulds together in a direction perpendicular to the junction faces of the chill moulds.

Abstract: The invention relates to the distribution on a receiving device of fibers carried by a gas current. To improve the distribution, the gas current carrying the fibers is subjected to the action of a gas layer which envelopes the current and of which the direction of flow in a plane tangent to the gas current differs from that of the gas current. The action of the gas layer results in an expansion of the current carrying the fibers. The invention is particularly useful where the fibers are received on a collecting device such as a foraminous conveyor belt, of large width.

Abstract: A process for drying or curing green wood including the heating of green wood in a heating enclosure to a predetermined temperature over about 120 F while maintaining the moisture content of the wood close to the original moisture content of the felled wood, and then immediately cooling the heated wood with a cooling fluid at a temperature and humidity substantially less than the temperature and relative humidity of the heating enclosure for a time period sufficient for the wood to reach substantially the reduced temperature of the cooling fluid for normally removing at least about 5% of moisture from the green wood. The green wood is conditioned by the cooling step for subsequent drying steps in which moisture removal rates are substantially higher than moisture removal rates under prior conventional drying steps. The green wood process as set forth is effective to minimize staining of the wood.
