Filed: 1991-11-26
Abstract: A method for making low density (0.8-1.1 lb/cu.ft.) expanded polymeric products uses blowing agent in an amount of only from 2 to 4.4 weight percent.  The process uses 2 to 5 expansion steps together with a polymer having a particular polydispersity, weight average molecular weight and Mz:Mn, this polymer having a greater expandability than conventional polymers.  The process requires only about half of the amount of blowing agent currently being used in commercially viable processes for making expanded polystyrene products.   The process can be used with or without a molding step.

Title: Dispensing apparatus for plastic bags
Inventor: WILFONG HARRY B JR
IPC: A47F9/04
Filed: 1992-08-12
Abstract: A dispensing apparatus is disclosed for serially dispensing flexible plastic bags from a wound package of bags which are joined along perforated severance lines.  The apparatus includes a panel, and at least one elongate dispensing slot extending through the panel.  The slot includes relatively narrow and linearly aligned outer edge portions, and a laterally extending tongue positioned between the outer edge portions.  Also, an opening is located on one side of the tongue.  In use, the opening is used to facilitate thread-up of the initial bag through the slot, and the two outer edge portions serve to engage and hold the bag in the slot.  During withdrawal, the tongue engages the central portion of the bag, and when the tongue engages the next perforated severance line, or the bottom of the cut out in the case of T-shirt bags, a significant resistance is imparted which causes the severance line to rupture, with the next bag positioned in the slot and ready to be engaged and withdrawn.

Title: Bioabsorbable stent
Inventor: STACK RICHARD S
IPC: A61F2/92
Filed: 1991-05-17
Abstract: A bioabsorbable stent (10, 50, 80, 90) for placement at the locus of a stenotic portion of a body passage, such as a blood vessel, which is flexible and compliant for safe and effective delivery to the site of the stenotic portion of, for example, a blood vessel, so as to avoid the disadvantages of chronic implantation, such as arterial rupture or aneurism formation while exposed to the continuous stresses of a beating heart. The stent is formed from a bioabsorbable material and is porous or has apertures defined there through to facilitate tissue ingrowth and encapsulation of the stent. The stent is encapsulated and biodegrades or bioabsorbs within a period of days, weeks or months as desired following encapsulation to thereby minimize the likelihood of embolization or other risks of the dissolved material and to avoid the disavantages of chronic implantation.

Patent CA-2084819-A1 (CA)
Title: In-pattern on-line coating defect detection system
Inventor: FRAZEE RALPH E JR
IPC: G01N21/95
Filed: 1992-12-08
Abstract: In-Pattern On-Line Coating Defect Detection System Abstract A defect detection system (10) of this invention applies one or more spacially-separated, orthogonally-aligned light beams (22 and 24) to a coated fiber (32) such that the light passes through the entire width of both the fiber (32) and its applied coating (31). As the light passes through a fiber (32) and coating (31) of good quality, a particular pattern, with a predictable intensity level, is produced by the forward scattered portions of the light beams directed through the coated fiber (32). In accordance with the present invention, the intensity of the forward scattered patterns is continuously monitored by a series of photodiodes (48) each located within a lens/detector module (40, 42, 44 and 46) and positioned precisely within the expected forward scatter pattern. Various defects in the coating cause the path of the light passing through the coated fiber (32) to be altered, thereby directing some of the forward scattered light outside the detection area of the photodiodes (48). Such distortion to the forward scatter patterns causes the light intensity level measured at the photodiodes (48) to decrease. Therefore, by continuously monitoring the forward scatter patterns for a reduction of light relative to the light intensity expected, the present invention provides reliable and accurate means for detecting temporally short defects, such as air bubbles, which may be present within the coating (31) of a fiber (32).
