Title: Method for the production of ductile cast iron
Inventor: BAECKERUD STIG L
IPC: G01N33/20
Filed: 1991-10-11
Abstract: A method in the production of ductile cast iron comprising controlling and correcting the composition of the cast iron melt. The method further comprises extracting a sample from the melt, the mother melt, and adding an amount of an oxide, a sulphide or an oxy-sulphide with the ability to oxidize an amount of the modifying agent present in the sample and corresponding to the fading rate occurent during the casting process as a whole. The sample is permitted to solidify in a sample vessel equipped with two thermocouples, one in the centre of the sample vessel and the other in the vicinity of the sample vessel wall. The temperature and time are recorded during the process of solidification in a manner known per se and nodularity is calculated. If the amount of modifying agent is too low to secure a fully nodular graphite throughout the whole casting period, an appropriate amount of modifying agent is added.

IPC: G05B13/02
Filed: 1993-04-27
Abstract: The use of nonmonotonic or "common sense" reasoning has often been advocated to speed up reasoning systems. The difficulty has always been that nonmonotonic reasoning requires consistency checks, which are even more computationally intractable than the monotonic reasoning normally used in reasoning systems. Dislosed herein are methods and apparatus for making consistency checks tractable by performing them over a limited context using fast sufficient consistency checks. The results are approximate, but approximate results are expected in nonmonotinic reasoning. Include in the disclosure are techniques for selecting the limited context and making the fast sufficient consistency checks and a default reasoner which employs the techniques to check the consistency of a default conclusion with a limited context.

Title: Human retrovirus receptor and dna coding therefor
Inventor: MERUELO DANIEL
IPC: C07K14/705
Filed: 1991-12-13
Abstract: A human protein molecule termed H13 has strong sequence homology to murine retrovirus receptor proteins and encodes a human retrovirus receptor. DNA encoding the H13 protein, cells transformed and transfected with this DNA and antibodies specific for H13 are disclosed. The H13 protein or its functional derivative can be used for preventing or treating retrovirus infection by administration to a subject of the H13 protein or a functional derivative thereof, or an anti-H13 antibody. Transgenic animals, useful as animal models for diagnosis or therapy of human retrovirus infections, are made by transfecting embryonic cells with the H13-encoding DNA. A chimeric retrovirus receptor protein comprises the H13 sequence, having substituted therein, amino acid residues encoding a murine retroviral receptor. Expression of the chimeric receptor in human cells allows infection or retrovirus-mediated gene transfer with murine retroviruses, which provides an extra measure of safety for in vivo gene therapy. DNA encoding the chimeric retrovirus receptor protein, cells transformed with this DNA, and methods for rendering a cell susceptible to infection by a retrovirus normally incapable of infecting that cell are disclosed.

Abstract: Abstract of the Disclosure Construction and method of making a decorative cracked glass laminate in tile, panel, sheet, plate, veneer or in situ form.  It comprises three layers laminated together, an inner backing layer, a substantially light-transparent outer layer, and a decoratively cracked glass intermediate layer sandwiched between the inner and outer layers.  the intermediate layer, preferably a mirror, is made of tempered glass and the outer layer is made of annealed glass.  The laminate is made by laminating the inner and outer layers to the intermediate layer while it is in uncracked condition, and then causing it to crack in situ as by cutting into an exposed edge.  Alternatively, the two glass layers may be laminated together and then laid in a backing layer of the two-glass laminate.

Title: Compressible Screw-Type Locking Mechanism
Inventor: ERICKSON ROBERT A
IPC: F16B23/00
Filed: 1992-05-18
Abstract: The present invention relates to compressible screw-type locking mechanism including an oversized locking screw (12) and a tool for compressing and rotatively driving the oversized locking screw (12) is a head portion (12a) and extending downwardly from the head portion is a threaded shaft (12G). At least one longitudinal slot (18) extends through the head and at least partially through the shaft to form a locking screw with plural resilient segments. The locking screw assumes a normal expanded state with its threaded pitch diameter being oversized with respect to its companion bore. The locking screw is compressed by engaging the head (12a) thereof with the tool (16). In one embodiment, the compression of the locking screw is achieved through a torquing ac-tion. In a second embodiment, the compression is achieved by the axial movement of the tool. In either case, by relieving the ap-plied torque or removing the tool. In either case, by relieving the applied torque or removing the tool from the locking screw head results in the locking screw expanding within bore and assuming an interference or locked fit within the bore.

Title: Recyclable Print-Tinted Paper
Inventor: PODOSEK EDWARD
IPC: B41M1/36
Filed: 1993-12-06
Abstract: A sheet of writing paper which is white, but which has been colored, or tinted to a pastel color by printing on its surface with a strippable or chemically removable ink. The surface printing with ink allows the paper to have a desirable tinted color, but allows the color to be easily removed so that the paper can be relatively easily recycled and reused without the normal problems associated with recycling of vat-dyed tinted papers. The surface printing can be accomplished by printing a random spotted pattern on the paper to provide for the perception of tinting. The invention allows the printed pattern to have a random-toned effect or allows the visual incorporation of words or symbols which would very subtly appear, macroscopically, in the tinting pattern.
