Title: Cvd diamond workpieces and their fabrication
Inventor: ANTHONY THOMAS R
IPC: C23C16/26
Filed: 1991-01-17
Abstract: CVD DIAMOND WORKPIECES AND THEIR FABRICATION     ABSTRACT OF THE DISCLOSURE The present invention is addressed to a method for making diamond workpieces which comprises the steps of placing in a chamber a pattern heated to an elevated CVD diamond-forming temperature, the pattern being the negative of the workpiece. A hydrocarbon/hydrogen gaseous mixture is provided within the chamber in the next step. The gaseous mixture then is at least partially decomposed in the chamber to form/deposit the CVD diamond layer on a surface of the pattern. In the final step, the CVD diamond layer is removed from the pattern to form the workpiece which possesses the surface characteristics of the surface of the pattern upon which it was formed. Appropriate workpieces that can be made in accordance with the inventive process include convergent, divergent, and flat optical mirrors; nozzles, wire dies, and tubular shaped workpieces; curved, angular, and re-entrant shaped workpieces useful in grinding, cutting, wear, and other applications; and a variety of additional products.

Title: Bilipeptides and processes for their preparation
Inventor: WU TAI-WING
IPC: C12P21/02
Filed: 1991-02-06
Abstract: ABSTRACT         Novel bilipeptides are provided which retain the pigment binding site and its neighbouring amino acid sequences of natural delta-bilirubin in solution, but are of much smaller molecular size than delta-bilirubin. Under certain circmstances, they are useful as cytoprotectants and show enhanced activity over delta-bilirubin in such applications. In place of the albumin chain of delta-bilirubin, they have an amino acid sequence of up to 50 units including a sequence-Lys-Glx-Arg- with Lys covalently linked to a propionic acid group on the bilirubin nucleus. Processes for making such bilipeptides are also provided. One such process comprises activating unconjugated bilirubin with an appropriate site specific reagent under specific conditions of pH, and reacting the complex so formed with albumin or a peptide of the general formula R-Lys-Glx-Arg-R'. Another such process for making bilipeptides comprises subjecting delta-bilirubin to controlled enzymatic cleavage to reduce the chain length of the albumin protein attached to the bilirubin component.

Title: Phosphorous derivatives of mannich products as antifoulants and metal deactivators in hydrocarbon fluids
Inventor: ROLING PAUL V
IPC: C10G7/10
Filed: 1991-07-10
Abstract: Abstract of the Disclosure Phosphorus derivatives of Mannich products are disclosed as useful antifoulants in liquid hydrocarbonaceous mediums during processing at elevated temperatures.  Simultaneous with antifoulant protection, the derivatives deactivate metal contaminants such as Fe and Cu present in the medium so as to inhibit the formation of free radicals in the medium that would, in the absence of treatment, lead to the decomposition of the hydrocarbon medium.  The derivatives are formed by reacting a phosphorus compound containing an acidic P-H bond with the reaction product of a p-alkylphenol, polyamine, and aldehyde.

Title: Bore-hole packer
Inventor: TOON DONALD A
IPC: E21B33/127
Filed: 1991-09-25
Abstract: Abstract of the Disclosure Title: BOREHOLE PACKER     The packer (4) is for use in isolating long lengths (ie heights) of a borehole (2), eg between sampling points.  The packer includes bentonite (23) which is activated by the natural groundwater in the borehole.  The water is admitted into the bentonite through narrow portholes (21), which delays the flow of water into the packer.  The water is distributed evenly throughout the bentonite by means of blotting paper (14,16), which soaks up the incoming water and prevents the water passing to the bentonite until the blotting paper is all saturated.  Alternatives to the use of blotting paper, to transmit the water evenly over and through the whole body of bentonite, include perforated corrugated plastic,  corrugated cardboard, and perforated plastic pipes.

Title: Illumination system for scanner
Inventor: MCMILLIN JOHN V
IPC: G02B6/04
Filed: 1991-10-18
Abstract: ABSTRACT OF THE DISCLOSURE The invention concerns an illumination system for moving sheets which are scanned by an imaging device. Because the moving sheets can flutter as they are scanned, their distance from the imaging device can change, thereby changing the amount of light captured by the imaging device. The invention reduces this change, and provides a method for selecting a distance at which the changes are minimal. The invention also provides the following features: (1) An apparatus for illuminating the sheet uniformly, thus reducing the possibility that naturally dark regions of the sheet may be interpreted as data. (2) A method of selecting an optimal angle of incidence for incoming light, in order to maximize contrast between the sheet and data marks. (3) A procedure for collecting maximal light from a lamp, using a fiber optic bundle which is of a fixed diameter. (4) A procedure for improving light capture or image contrast, based on measured values of document specularity, mark specularity, fiber optic numerical aperture, reflectance of the sheet, and diffusion coefficient of the sheet. (5) Fiber optic light projectors whose projecting ends are bevelled in a single facet, thereby increasing the angle of incidence, without changing position of the fibers. (6) A procedure for accommodating the image shift caused by glass plates which guide the moving sheets, and through which the imaging device must look. (7) A procedure for reducing cross-talk between two illuminator-imaging device assemblies, which image opposite sides of the same sheet.

Abstract: A device for reheating and dispensing cooked meals arranged on a meal tray and stored on stand-by in a refrigerated enclosure. Each tray may contain different foodstuffs, and can therefore be selected by the consumer. Reheating is carried out by a sliding oven (7) on an endless ballscrew (3), assisted by two slide rails (5). The oven (7) moves in front of the selected tray. In the refregerated enclosure (1), trays are stacked on shelves (21) with slide rails (23), and endless screw (8) slides a camshaft (10) provided with snugs (12) so that it triggers the tray-moving mechanism (11), and a detector (14) determines which snug corresponds to the selected tray. Once the snug is engaged in the mechanism (11) the camshaft (10) rotates from left to right and vice-versa to activate the mechanism's (11) rocker bars (22) which slide the tray into or out of the oven.
