Abstract: A device for treating obstructions in vessels or small openings in the body, comprising a rotatable ablator tip which is guided to the obstruction in a reduced diameter configuration, expanded and rotated to remove the obstruction, and contracted to remove the device from the body. The variably expandable abrasive tip coil in one embodiment is actuated by piston means within the coil. A pair of collars is attached to the ends of the coil, and the piston effects relative longitudinal axial movement of the collars and the respective ends of the coil tip. When the ends of the coil tip are so moved, expansion and contraction of the diameter of the coil tip results. In another embodiment, the expansion tip coil is actuated by an expandable and contractible bellows disposed within the coil. In another embodiment, the expansion and contraction of the coil tip are affected by longitudinal axial movement of an internal coil attached to one end of the coil tip, within an outer coil attached to its other end. In another embodiment, expansion and contraction of the coil tip are effected by an inflatable balloon disposed within the coil tip. The balloon expansion means enlarges preferably at the central portion of the coil to make a bulge. In alternative embodiments, there is provided a combined atherectomy and balloon angioplasty device employing either a fixed or variable diameter rotatable abrasive burr, and an angioplasty balloon disposed proximal to the burr.

Title: Lateral adjustment mechanism for a chair armrest
Inventor: DOERNER FRANK
IPC: A47C7/54
Filed: 1994-06-13
Abstract: A lateral armrest support adjustment mechanism has a bracket attached underneath the chair with a slot receiving a lateral extension of the armrest support.   A rack of teeth projecting into an opening extending along the lateral extension of the armrest support receives two pins depending from a knob carried on the bracket.  A bar is biased into blocking relation with the teeth of the rack of teeth in order to latch the mechanism.  When a user turns the knob, the pins walk along the teeth in order to laterally adjust the armrest support.  The knob has  four  circumferentially  equally  spaced  notches  which facilitate ready gripping and turning by the user.  The bracket has a square hole through one of its faces and a circular hole registered with the square hole through its opposite face.  This allows the bracket to be utilized with another lateral adjustment mechanism.   More particularly,  a post with a square cross-sectional portion may be received through the further bracket openings and through a slot in an armrest support member.  A knob may then be threaded to the post so that the knob extends through one of the bracket openings and pushes the armrest support extension against a face of the bracket thereby frictionally locking the armrest support to the bracket.   Adjustment is accomplished by loosening the knob, moving the armrest support, and retightening the knob.

Title: A process for the production of granules suitable as wetting agents, detergents and/or cleaning products
Inventor: RAEHSE WILFRIED
IPC: C11D11/04
Filed: 1993-02-04
Abstract: Granulates are produced from their aqueous solutions and/or suspensions by fluidized bed spray granulation in a hot fluidizing gas in the normal pressure range. Overheated steam is used as fluidizing gas and the granulate is evacuated from the granulator before it risks being damaged by heat exposure. If required, the storage-stable looseness and pourability of the partially dried substance is ensured by admixture of components capable of binding limited amounts of water and/or by a subsequent treatment. The system is a closed system in which a current of steam circulates, from which the water evaporated from the process substance is drawn as a partial current and to which the released thermal energy is supplied again. The process is free from exhaust fumes and contanimated waste waters, without diminishing the quality of the granulate produced on a large scale.

Filed: 1994-10-04
Abstract: A METHOD AND APPARATUS FOR RECEIVING SIGNALS IN A           MULTI-PATH ENVIRONMENT Abstract Signals from multiple signal paths are received using a multi-element antenna 20 and a beam-forming network 34. Signals from each of the antenna elements are sampled to form a sample vector. Several sample vectors are used to form an auto-covariance matrix. A singular value decomposition of the auto-covariance matrix is used to form three matrices. The first matrix is used to determine the number ofsignal paths and the second matrix is used to form several polynomials. The polynomial roots that are on or near the unit circle are used to determine points on the unit circle that are associated with each signal path. Each point on the unit circle is used to calculate weights for a beam-forming network 34 that forms a receive beam for each signal path. FIG. 3

Title: Soft Tissue Stapling Buttress
Inventor: COOPER JOEL
IPC: A61B17/11
Filed: 1995-01-09
Abstract: To  reinforce  a  line of  surgical  staples  in host tissue, a strip of xenogeneic or autogenic tissue, such as cross-linked  pericardium  or  dura mater harvested  from horses,  cows,  pigs,  sheep and humans,  is appropriately adhered to the, apposed surfaces of a staple cartridge supporting jaw and an anvil jaw of a surgical staple gun so that when tissue to be excised is positioned between the jaws  and  the  staple  gun  is  fired,  the  staples  will penetrate  the  two  layers  of  animal  tissue  and  the intervening host tissue.  Actuation of the cutting blade on the stapler or the use of a separate cutting instrument severs the tissue and the two layers of animal tissue along the staple line.  When used in performing a lung reduction procedure, the animal tissue reinforcing strips create an air-tight seal about the staples preventing air leaks.  The structure for holding the bovine pericardium strips may include  a  buttress  member  formed  from  a  nonwoven polyethylene sheet material to which the pericardium or dura mater strips is attached using a basting stitch.
