Granted: 1992-07-07
Abstract: ABSTRACT            TUBE HAVING FILTER THEREIN FOR USE IN THE CASTING OF METALS           A tube of refractory material having a filter therein for use in the casting of molten metals is made by forming a tube of fibrous refractory material, a binder and optionally particulate refractory material, inserting a filter into the tube, deforming the wall of the tube around the filter so as to hold the filter in place and causing or allowing the binder to harden.  The filter may be a honeycomb type of structure having cells which extend from one face to an opposite face, or a structure having interconnecting cells such as a ceramic foam.  In use the tube is inserted in a mould sprue which communicates directly with the mould cavity.

Abstract: 795,850. Bating leather. ROHM & HAAS GES. Oct. 22, 1956 [Oct. 21, 1955], No. 32143/56. Addition to 776,323. Class 76. Green or soaked hides or skins which have been fleeced or dehaired by the application of enzymic material in the form of a powder as disclosed in the parent Specification are subsequently enzymically bated at a pH of 3-5. Proteolytic enzymes such as pancreatic tryptase, bacterial proteases, or preferably mould fungi tryptases may be employed. By bating at such an acid pH the creation of loose grain produced by proteolytic enzymes acting at an alkaline pH is avoided. The bating lasts from 6 to 36 hours and if necessary may be preceded by a weak enzymic bating at an alkaline pH. In addition to the proteolytic enzymes, mould fungi carbohydrases and/or lipases and advantageously one or more neutral salts such as sodium chloride, ammonium sulphate, or sodium tripolyphosphate may be present. Examples are given of the dehairing by enzymic means and subsequent enxymic bating of: (1) dry goatskins, (2) salted sheepskins, (3) salted calf skins, (4) dry goatskins.

Title: Quench assembly design
Inventor: KOROS ROBERT M
IPC: B01J8/04
Filed: 1990-07-26
Granted: 2000-04-18
Abstract: According to this invention, a quench assembly having improved mixing efficiency comprises a series of mixing zones: quench fluid inlet zane: quench box mixing zone; a jet stirred mixing zone: and a distributor zone. In the quench fluid inlet zone, quench fluid is introduced to fluid from the catalytic bed above. The quench fluid is introduced through holes in a quench pipe, creating a jets of quench fluid which entrain and mix the reactant fluid, typically partially reacted, from the bed above. This mixing zone is separated from the quench mixing zone by means of a horizontally disposed plate having a central opening therein. The reaction fluid and quench fluid enter the quench mixing zone through the central opening in the plate separating the two zones and impinge on a bottom bench mixing zone plate, where the gases are turned radially outward and passed over and around a series of mixing baffles. A plurality of pipes is located in an annular ring near the periphery of the bottom plate of the quench mixing zone for introduction of the quench gas and process fluid into a jet stirred mixing zone. Thus, the flow of fluids coming out of the quench mixing zone is introduced in a swirling direction into the jet stirred annular mixing zone, where the fluids arc further mixed by mutual entrainment. Next, the fluid is turned downwardly through a central opening in a plate separating the jet stirred one from the distributor zone. The distributor zone is provided with a distributor tray for distributing the fluid to the catalyst bed below.

Abstract: A technique for resolving whole-cycle ambiguity that is inherent in phase-angle measurements of signals received from multiple satellite-based transmitters in a global positioning system. The relative position of a secondary receiving antenna with respect to a reference antenna is approximately known or approximately initially determined and then measurements from a minimum number of satellites are used to determine an initial set of potential solutions to the relative position of the secondary antenna that fall within a region of uncertainty surrounding the approximate position. Redundant measurements are taken from one or more additional satellites and used to progressively reduce the number of potential solutions to close to one. Even if the number of potential solutions is not reduced to one true solution, the number can be further reduced by using additional measurements taken at different time intervals, at which different satellite geometries prevail. The disclosed technique produces rapid elimination of false solutions and permits real-time computation of relative position in kinetic positioning applications, and of angular orientation in attitude determination applications.
