IPC: C08K5/00
Filed: 1993-09-14
Granted: 2004-12-28
Abstract: Recycled mixtures of plastics, predominantly thermoplastics, as predominantly produced in the household, in commerce and also in industry and useful material collections, can be stabilized against thermooxidative degradation by adding a combination of a sterically hindered phenol with an organic phosphite or phosphonite and an inorganic compound from the series consisting of metal oxides, hydroxides and carbonates.

Title: Automatic pill dispensing apparatus
Inventor: SHAW THOMAS J
IPC: B65B1/30
Filed: 1994-01-04
Granted: 2005-05-10
Abstract: An automatic pill dispensing apparatus (10) is provided having a plurality of cartridges (38) supported in guide slots (30) within a housing (12). The apparatus is integrated with a microprocessor (150) operating according to an algorithm, which receives, stores and processes prescription schedule data. Each cartridge (30) has a plurality of compartments (60) disposed about its periphery for containing medication to be dispensed at proper intervals at a dispensing position.      An alarm is sounded for the user when the cartridges (38) are ready to be positioned for dispensing medication according to the prescription schedule. A dispense bar (44) is manually actuated by the user to eject scheduled medication into a tray (20) for user acces.      If the user fails to dispense scheduled medication, it is withheld to prevent double dosing at subsequent dispensing times. The plurality of cartridges (38) enable filling by a pharmacist of independent multiple prescriptions. After the cabinet housing is loaded for use, the housing is locked to prevent access unless a security code is entered into the processor. A dislodging wire (52) sweeps through each compartment as the dispense bar is depressed, thereby dislodging the medication from the compartment (64) for user access.
Patent CA-2154064-C (CA)
Inventor: CACACE ANTONIO GIORGIO
IPC: C22B5/10
Filed: 1994-01-17
Granted: 2009-12-22
Abstract: A method is disclosed of producing a corrosion resistant product from a billet comprising a core of finely divided ferrous swarf compacted into briquettes in a stainless steel jacket and in which the billet is heated to a temperature at which it becomes sufficiently plastic to be worked into a finished or semi-finished product by an operation such as rolling. An additive is pre-mixed with the swarf which, when the billet is heated, reacts to form an atmosphere inside the jacket which displaces or prevents the formation of carbon dioxide and/or other gases which at elevated temperatures would oxidise the stainless steel to form chrome oxides at the interface between the jacket and the core. The additive is preferably in powder form. Examples of suitable additives include urea and ammonium chloride.

Abstract: The biological fluid analyzing device for analyzing biological fluid by measuring optical characteristics of a sample has a sample receiving port 1 and a pump connection port 5.  Between the sample receiving port 1 and the pump connection port 5, the analyzing device has either a combination of at least one sample-treating chamber 2a, 2b, 2c and at least one optical-measuring chamber 3a, 3b, or a combination of at least one sample-treating chamber,  at least one optical-measuring chamber and at least one waste liquid reservoir 4.  The sample receiving port 1 is connected with one sample-treating chamber; the pump connection port 5 is connected with a pathway 6 or waste liquid reservoir 4; and the sample-treating chamber and optical-measuring chamber are interconnected with the pathway, or the sample-treating chamber, optical-measuring chamber and waste liquid reservoir are interconnected with the pathway.  This construction allows a series of reaction steps to be performed without being affected by physical properties of a liquid sample and thereby assures high level of precision in analyzing the liquid sample.  This construction also enables measurements to be made easily.

Title: Vectors and use thereof for capturing target genes
Inventor: SKARNES WILLIAM C
IPC: C12N15/10
Filed: 1996-01-09
Granted: 1999-05-04
Abstract: The invention relates to secretory gene trap vectors and methods of using such vectors to isolate extracellular proteins and to make cells and organisms with mutant secretory genes. The vectors encode a type II transmembrane domain and a lumen -sensitive indicator marker and optionally, a selectable marker and an exon-splice acceptor site. The gene isolation methods involve stably introducing the secretory trap vectors into an endogenous gene whereby the expression of the resultant fusion protein provides a differential expression of the indicator marker depending on whether the endogenous gene provides an N-terminal signal sequence.

Abstract: An inflatable serving tray that is convertible into a booster seat. The device consists of a predefined surface area that allows for securement of a serving plate and beverage in such a manner so as to avoid spillage during consumption. Should spillage occur, a recess is provided so as to contain the spillage and direct it to the beverage holder where it can be easily removed. In addition, when the serving tray is not in use, the device may be used as a booster seat so as to raise the child to approximate the level of an average adult while seated. As a booster seat a recessed section operates to position the child correctly so as to help prevent the child from accidentally falling off the booster seat as well as contain liquids such as excess water from a child's swimming suit. A slot is provided for placement of napkins or eating utensils. Through hole chambers reduce the amount of air required for inflation and eliminate the pillowing of an inflatable device by providing internal surface support. A handle allows ease of transport and allows for securement with a seat belt.

Abstract: The present invention is a process for hydrophobically modified emulsion polymers, polymers obtained thereby, waterborne coating compositions containing the polymers and a coated substrate coated with the coating composition. The emulsion polymer is formed by first combining hydrophobic polymeric compound and .alpha.,.beta.-ethylenically unsaturated monomer, and surfactant to form a mixture and subjecting the mixture to high stress techniques to form stabilized particles of the hydrophobic polymer and monomers, in the aqueous phase, said particles having a particle size between 50 and 500 nm. The polymerizable material within the particles is polymerized to form a hydrophobically modified core polymer. Additional monomers including at least one .alpha...beta.-ethylenically unsaturated hydrophilic monomer are then added to the core polymer and polymerized by emulsion polymerization, to form a hydrophobically modified core-shell emulsion polymer. To form a coating composition, the emulsion polymer is combined with additional components such as pigments, crosslinkers, plasticizers and solvents. The coating is applied to a substrate to form a coated article.

Abstract: An automated biological screening system (500) obtains biological and procedural data from a slide set of a selected clinical laboratory (210). The integration system (500) tests the data on standardized criteria and passes and fails the data in selected categories (30, 40, 50, 60, 70). The results of the assessment are used to make process adjustment recommendations (218) based on the results of a laboratory process adjustment procedure (214). Assessment and adjustment may continue until data from a slide set from the selected clinical laboratory passes in each category (30, 40, 50, 60, 70). The integration system (500) then sets up, calibrates and installs the automated biological screening system. During operation, the integration system (500) continuously monitors (226) biological data generated by the automated biological screening system. The biological data may also be stored in a central product/service database (232) for additional monitoring.

Abstract: A stroke limiting structure for use with a lift control system on an implement includes a reciprocating link operably connected to a hydraulic cylinder and to a lift wheel assembly on an implement frame section. The link is connected by a lost motion connection to depth gauging structure including gauge plates pivotally supported on a carrier. The plates are rotatable between disengaged and engaging positions without need for tools and are maintained together on the carrier to eliminate loose parts that could be misplaced or lost. The plates in the engaging position determine the lowermost position of the implement and provide a positive mechanical stop for the implement to eliminate depth control problems caused by cylinder leakage or the like. The lost motion connection eliminates unwanted movement of the plate carrier and facilitates gauge plate pivoting for depth adjustments.
