Title: Sol-gel process for providing a tailored gel microstructure
Inventor: WANG SHIHO
IPC: C01B33/152
Filed: 1992-12-11
Abstract: An improved sol-gel process for fabricating large, crack-free gel monoliths (e.g., of silica) is described in which a specially-tailored gel microstructure is provided by adjusting the relative concentrations of an alcohol diluent (e.g., ethanol) and/or one or more catalysts (e.g., HC1 and HF). Controlled variations in the gel's average pore radius, bulk density, rupture modulus, and elastic modulus over a wide range can be tailored in this fashion.  This enables the process to be optimized for the particular application involved.

Title: Method and apparatus for sterilization and separation of plastic and non-plastic medical wastes
Inventor: ANTHONY FRANK H JR
IPC: B29B17/02
Filed: 1994-08-16
Abstract: Medical waste products including plastic and non-plastic elements are placed in a metal container which includes a raised insert element for supporting the waste above the bottom of the container.  The container and used medical waste products are subjected to dry heat treatment at temperatures below the waste material flash points but of sufficient temperature and for a sufficient time to melt the plastic elements as well as to sterilize the contents. During the heating process the metal, rubber and other non-plastic elements remain on the raised insert; whereas, the molten plastic flows through or over the side of the insert to the bottom of the container. Upon cooling the plastic and non-plastic components of the medical waste products are separated as well as being sterile such that the container can be opened and the contents separately handled for appropriate recycling.  The dry heat generator conveniently may be placed in a medical office or the like and is microprocessor controlled to obtain the desired end products.  The processor additionally controls an electrical interlock system whereby the heat generator unit may not be opened until an entire heat cycle has been completed, and the waste products have cooled to a safe temperature.

Title: New products of depolymerizing partially acetylated chitosan, new enzymes and new thermoactinomyces strain for the production thereof
Inventor: BRODEL BRUNO M L
IPC: C12N9/42
Filed: 1993-08-31
Abstract: It has been found that various strains of the genus Thermoactinomyces produce substantial quantities of chitosanase when cultivated under appropriate conditions and that a new strain of Thermoactinomyces with the identification I-1052, Institut Pas-teur, Paris, is of special interest. A new thermostable enzyme has been isolated from the culture broth of this new strain. This new enzyme hydrolyzes chitosans with varying acetylation degrees. New depolymerized partially acetylated chitosan products are ob-tained by the use of these new enzymes and are characterized by their viscosity, molecular weight distribution and degree of acety-lation.

Title: Biosensor for detection of and distinguishing between cholinesterases inhibitors
Inventor: TUSAROVA IVANA
IPC: C12Q1/46
Filed: 1993-09-01
Abstract: The invention relates to a biosensor of cholinesterase inhibitors in air, water, foodstuffs, soil, at surfaces and in extracts from samples, comprised of cellulose textile with bioafinity immobilized and stabilized cholinesterase, colour standard and of a carrier from substrate and chromogenic agent and its application to the detection of and distinguishing between cholinesterase in-hibitors. In distinguishing between the inhibitors by a biosensor in case of cholinesterase immobilized at cellulose textile of the biosensor after inhibition by organophosphorous or carbamate inhibitor, hydrolytic activity restores the activity of nucleophilic agents. According to the level of the restored hydrolytic activity of the immobilized cholinesterase in relation to the exposition time to reactivators, e.g. to quaternary aldoximes or water, and according to the activity change of the immobilized cholinesterase exposed in the inhibitor solution and in the inhibitor solution containing ions, e.g. natrium, calcium or ammonium ions, the type of the organophosphorous and carbamate inhibitor is determined.

Title: An Arrangement with a Plurality of Surge Arresters
Inventor: HINRICHSEN VOLKER
IPC: H01B17/46
Filed: 1993-10-22
Abstract: Abstract An Arrangement with a Plurality of Surge Arresters In an arrangement with a plurality of surge arresters (1, 11) that are arranged so as to be coaxial and are connected to common conductor rails (5, 20, 22) by connecting lines (4, 17, 18, 19), the first connecting lines (4) extend essentially radially away from the longitudinal axis of each surge arrester (1), in a direction that is away from the position of the exhaust openings (2, 3) on the periphery of the surge arrester (1).            Thus, in the event of an arc, the current flowing through the connecting line (4) generates a magnetic field that pushes the arc away from the surge arrester (1).  The exhaust openings (2, 3) on each surge arrester (1, 11) are so positioned that the arc is not formed in the area between two adjacent surge arresters (1, 11), and is pushed away from the surge arrester by the components forces of the magnetic field.  In addition, the present invention provides that the direction of the current in the connecting lines subtends an angle of less than 90° with the common conductor rails, so that the current in the common conductor rails also contributes to generating the desired magnetic field.

Title: System and method for generating precise position determinations using gps and pseudolites
Inventor: COHEN CLARK E
IPC: G01S19/11
Filed: 1994-03-22
Abstract: A GPS system for determining precise position, for example of an aircraft during its final approach to landing.      The GPS system (20) includes a ground based GPS reference system which receives, with a reference receiver, GPS signals (25) and makes carrier phase measurements. The GPS reference system generates and broadcasts one or more pseudolite signals (27) each having a carrier component and a data link signal (30) having data representing the phase measurements made by the GPS reference system. The GPS system includes a GPS mobile system which receives, with a position receiver, the same GPS signals as were received by the reference receiver and the data link and pseudolite signals broadcast by the GPS reference system. In response to the phase measurements made by both the reference receiver and the position receiver during an initialization period, the position receiver resolves the integer wavelength ambiguities associated with the phase measurements. The resolved integer wavelength ambiguities are used by the position receiver after the initialization period to generate precise position determinations for the GPS mobile system.
