Patent CA-1296505-C (CA)
Title: Continuous casting of thin metal strip
Inventor: HERBERTSON JOSEPH G
IPC: B22D11/06
Filed: 1987-05-06
Granted: 1992-03-03
Abstract: ABSTRACT     The invention provides method and apparatus for continuously casting metal strip of a predetermined transverse cross-sectional area.  The method includes the steps of providing molten metal above an inlet structure having a plurality of passages for the liquid to flow through. The total cross-sectional area of the passages is greater than the predetermined transverse cross-sectional area of the cast metal strip and the metal flows through the structure at a selected average velocity.  The liquid is received in a work zone defined by a supporting, chilled and movable substrate and is bordered by an upstream edge structure where the substrate meets the work zone and by side edge structures between the upstream edge structure and the downstream exit where the cast strip leaves the work zone.  The substrate is driven at a velocity greater than the average velocity of metal flow so that a constrained pool of metal fills the work zone and a shell of solidified metal grows on the substrate in the work zone with a layer of molten metal in contact with the inlet structure.

Title: Photo stable pigment containing composition
Inventor: DEGANI YINON
IPC: C09D7/61
Filed: 1987-10-26
Granted: 1992-09-29
Abstract: PHOTO STABLE PIGMENT CONTAINING COMPOSITION     Abstract Paints and coatings involving semiconducting pigments such as titanium dioxide generally degrade because of oxidation of the binder by reactants that are photochemically produced on the pigment surface, and because of direct binder oxidation by charges that are photogenerated in the pigment. In titanium dioxide, this interaction is substantially reduced by avoiding reduced species and by introducing into the titanium dioxide trap states where photogenerated electron-hole pairs recombine by processes such as prolonged milling. Through these expedients, a substantial increase in the stability of the pigment containing composition is obtained.

Abstract: METHOD OF PURIFYING AND DEPOSITING GROUP IIIa AND GROUP Va COMPOUNDS TO PRODUCE EPITAXIAL FILMS Abstract of the Disclosure The invention relates to a method for purifying group IIIa and group Va compounds for deposition onto a substrate to produce epitaxial films.  Prior art methods are unable to reproducibly produce quantities of high purity compounds.  The present invention provides a method for obtaining quantities of group IIIa and group Va compounds having semi-conductor grade purity.  Relatively crude group IIIa and group Va compounds are separated from impurities by conveying the mixture through separating columns (42,44, 110, 112).  The isolated group IIIa or group Va compound is condensed by a condenser (56, 122) and then collected (58, 129). The group IIIa compounds are additionally demisted (132) subsequent to condensing to improve the recov-ery of the purified compound.  Purified compounds may then be used in combination with a dopant to produce a crystal layer on a substrate by thermally decom-posing the compounds and dopant.

Title: Controlling access to network resources
Inventor: YUNG DARBY
IPC: H04L12/22
Filed: 1989-02-17
Granted: 1992-12-22
Abstract: ABSTRACT OF THE DISCLOSURE   A network includes digital computers, resources such as disk drives, printers and modems or disk files, file records or tasks, and a communications channel permitting data transfer between each digital computer and the resources. The function of mediating conflicting demands for network resources is distributed among the digital computers. A file server or other storage device connected to the communications channel contains an access log. Each digital computer accesses a required resource by first recording an entry in the access log identifying the required resource and then scanning the access log to locate any conflicting entry identifying the same resource. The access procedure is terminated if the conflicting entry is located and the recorded entry is then deleted. The digital computer otherwise accesses the required resource and deletes the recorded entry once use of the resource has terminated. Access to resources is restricted according to priority levels assigned to the various computers and by a virtual use log within the access log. A system operator can create records in the virtual use log indicating a non-existent use of network resources. Depending upon its assigned priority, each computer may scan portions of the virtual use log and locate conflicting entries which effectively prohibit the computer from accessing the identified resource.
