Title: Bath lift system with stabilizer
Inventor: CLARK GORDON J
IPC: A61G7/10
Filed: 1990-11-15
Abstract: ABSTRACT OF THE DISCLOSURE            A bath lift system for use in transporting a person into a bathtub, has an adjustable stabilizer.  The bath lift system has a chair unit, a base unit and a stabilizer which all interconnect and fit on to a bath tub.   The bath lift may operate by a water powered hydraulic  cylinder  located  on  the  chair  unit.    The hydraulic cylinder has a sleeve with extending brackets onto which a chair is attached.  The sleeve swivels and can be raised or lowered into the bathtub by the person being bathed.  The piston for the hydraulic cylinder is then attached to the base unit which has legs and suction cups for securing it in the bath tub. The stabilizer is secured to the base unit and is adopted to abut an upper edge  of  the  bathtub. This  should  provide  reliable stability  as  the  stabilizing  forces  are  transmitted perpendicularly between the stabilizer and the bath tub edge,   without   the   stabilizer   tending   to   slide horizontally.  The  stabilizer  can  be  fitted  with  an abutment member adapted to abut the bath tub edge, and provide location notches for engaging the chair, to limit rotation of the chair, to enable a user to readily sit down on or rise up from the chair. The stabilizer can be adjustable  both  horizontally  and  vertically  to  fit different size bath tubs.

Title: Percutaneous diskectomy procedure using a laser
Inventor: DAVIS JORDAN K
IPC: A61B17/3211
Filed: 1991-01-11
Abstract: A PERCUTANEOUS DISKECTOMY PROCEDURE USING A LASER      Jordan K. Davis Peter S. Hertzmann ABSTRACT OF THE DISCLOSURE The procedure for performing a percutaneous diskectomy using a laser comprises the steps of applying a laser beam generally along a first line to a herniated disk area, and applying a laser beam generally along a second line different from said first line to the herniated disc area.  The first and second lines along which a laser beam is applied are paths through which the laser beam is guided by an optical guiding means. According to the procedure, percutaneous diskectomy  n be performed readily as an outpatient procedure having minimal recovery requirements or restrictions.  The procedure time is decreased overall by 10-20 minutes because nucleus pulposus is vaporized and does not require removal with forceps or suction.

Abstract: ABSTRACT      A martensitic stainless steel article having an improved combination of strength, toughness, corrosion resistance and machinability.  The article is particularly adapted for use in the manufacture of holder blocks, frames, backers and similar articles for anchoring molds and dies.  The carbon and nitrogen content of the article are controlled to achieve the desired hardness.  Sulfur is controlled in accordance with carbon plus nitrogen to maintain the required machinability of the article.  Chromium and nickel are present for maintaining corrosion resistance, along with molybdenum, which also counteracts any adverse effects of increased sulfur content.  The article may be austenitized at a temperature within the of 1500 to 1750°F for about 1 hour per inch of thickness and either oil quenched or air cooled to achieve a martensitic structure.  Thereafter, the article may be tempered or stress-relieved at a temperature between 500 and 850°F for about 1 hour per inch of thickness and for a minimum of 2 hours.  After these heat treatments, the article will exhibit a hardness within the range of 30 to 40 HRC, preferably 35 to 40 HRC for higher strength applications, along with a drill machinability rating equal to or greater than 100.
