Title: Apparatus for fabricating dunnage material from continuous web material
Inventor: REICHENTAL ABRAHAM N
IPC: B65D65/40
Filed: 1992-06-16
Abstract: APPARATUS FOR FABRICATING DUNNAGE MATERIAL FROM CONTINUOUS WEB MATERIAL Apparatus for fabricating discrete segments of cushioned web material for use as dunnage. The apparatus includes a mobile supply cart having at least one substantially horizontal support ARM for receiving the hollow core of rolled web material. The apparatus also includes a separate driven rugation device with feed rollers for directing multiple plies of the web material in overlying, contacting relationship along a single path of travel. The separate cart and rugation device may be removably interconnected for lateral alignment. Driven interdigitized texturing rolls downstream of the feed rollers emboss a raised pattern on the web material, and a plurality of separating rollers downstream from the texturing rolls separate the plies of web material and direct them in divergent paths of travel. Combining rolls recombine the plies of textured web material such that the embossed areas of each ply do not directly overlie each other but are offset, creating void areas between the adjacant plies. A driven cutter downstream of the combining rolls severs the recombined offset embossed plies into discrete segments. The cutter may have a rotating disc blade with a peripheral edge which moves transverse to the longitudinal length of the plies to cut the plies. Last, driven exit rollers convey the cut segments of material from the rugation device.

Title: Apparatus and process for steam treating carbonaceous material
Inventor: KOPPELMAN EDWARD
IPC: C10L9/00
Filed: 1990-10-30
Abstract: An apparatus and process of steam treating carbon-aceous materials under a controlled temperature and pres-sure. The feed material is introduced into an autoclave or similar vessel and injected with steam at a high pressure and temperature for a controlled period of time to effect thermal restructuring of the carbonaceous material and to effect a conversion of the moisture and a portion of the volatile organic constituents therein to a gaseous phase.   Water, wax and tar are recovered during this process and the water may be used as a source of pre-heating feed ma-terial in another vessel while the tar may be used as a heat-ing source since it has a high heating value. The upgraded product is allowed to cool and then removed from tile reac-tion vessel. The invention alternatively contemplates use of a separate pre-heating chamber for the carbonaceous feed material.

Title: Clip for surgical purposes
Inventor: SCHULZE DALE
IPC: A61B17/068
Filed: 1993-05-07
Abstract: The invention relates to a clip for surgical purposes, made from bendable wire-like material. Conventional clips have an essentially rectilinear base from each end of which a limb projects. Upon application in endoscopic operations, i.e. when the clips are pushed forward through trocar cannulae, it is disadvantageous that the rectilinear base can only be so long that it can be pushed forward transversely through a trocar cannula. As a result, only small clips have been usable thus far with pre-set trocar diameters. According to the invention, a clip is so designed that the base is shaped bent backwards, starting from its centre section, on both sides, opposite to the direction of the limbs (42, 44), so far that the ends (12, 14) of the base touch or come close to each other, base (10) and limbs (42, 44) forming an essentially .OMEGA.-shaped contour, The bent-back configuration effects a substantial reduction in the lateral extension of the clip when it is pushed forward through the trocar cannula, so that endoscopically larger clips than usual can be set with a suitable clip setter.

Title: Process for recovery of oil from waste oil sludges
Inventor: HEUER STEVEN R
IPC: C10G31/10
Filed: 1991-08-09
Abstract: Commercially valuable oil is recovered from refinery-produced, Resource Conservation and Recovery Act classified, hazardous waste oil sludges by a series of volatilizing and condensing steps (which may vary depending on the oil, water, and solids content of the sludge) resulting in the production of nonhazardous water and solid waste by products. A pumpable, low viscosity, high oil and/or water-content sludge is first centrifuged in a centrifuge (14) to separate free oil and water. If the waste sludges are acidic or if nickel is present in the sludges in sufficient quantities so as to result in unacceptable levels in the TCLP leach filtrate, a base via line (17) (such as calcium oxide) is admixed in unity (19) with the thick waste oil sludge, centrifuge solids, or other sludges low in oil and/or water content to render the sludges basic. The basic, admixed sludges are heated to volatilize the contained water and oil in oil-water vaporization apparatus (23).  Dry, friable, deoiled solids are recycled via line (26a) with oily sludge feed to prevent material agglomeration and heat exchanger fouling. Oil and water vapor from the high-temperature volatilization apparatus (24a-24z) is recycled as an indirect heat source to the low-temperature volatilization apparatus (23). The volatilized oil and water are condensed in condensor (30) and combined with the oil and water centrate, and the oil and water are essentially separated as by gravity. The oil is separated from any entrained water and solids. The nearly oil free, nonhazardous waste water and nonhazardous, deoiled solids can be disposed of in a conventional manner, and the commercially valuable recovered oil is suitable for further refinery processing.

Title: Compression and reconstruction of radiological images
Inventor: WILSON DENNIS L
IPC: H04N1/41
Filed: 1993-06-08
Abstract: The present invention provides for a compression scheme (10) tailored to the compression of large radiological images processed with image processing workstations.      The compression scheme (10) is a variation of the CCITT JPEG compression scheme with special care taken to suppress blocking effects of the 8x8 discrete cosine transform used therein. In accordance with the present invention, an original image (11) is downsampled (12), then interpolated (14) back to its original size, resulting in a smoothed image (14a). The difference (13) between the smoothed image (14a) and the original image (11) is then compressed (15) using an 8x8 discrete cosine transform with 12 bit data. Major artifacts present in the original image (11) are due to the mis-matching of the low frequency components of the image at the edges of the blocks. When the low frequencies are removed by subtracting out the low frequency components, the artifacts disappear except in areas having very large dynamic changes. The compression scheme (10) of the present invention is particularly useful for archiving or telecommunicating images, achieving compression of more than 10:1 without losing the characteristics of the radiological image that permit effective diagnosis. A  reconstruction scheme is also disclosed which allows recovery of the image (11) from a compressed image file.
