Patent number: 5285794Abstract: A method and apparatus for monitoring the respiratory gas of a patient includes an adjustable volume gas mixing chamber which allows for the differences in lung capacity of patients from neonate to adult. A constant flow of a therapeutic gas mixture is measured by a flow meter in a supply line leading to a face mask breathing device. The mask is by-pass connected to the supply line such that the patient inspires from and exhales into the flow from the supply line. Both by-pass and expired gas mix and enter the adjustable-volume chamber, which contains an internal fan and sensors for detecting percentage content of oxygen and carbon dioxide. The chamber is adjusted to a volume where the sensor readings become stable rather than pulsatile. The change in percentages of oxygen and carbon dioxide content in the chamber, as compared to the content in the supply gas, is then entirely due to total-body consumption and production.Type: GrantFiled: December 14, 1992Date of Patent: February 15, 1994Assignee: Temple University of the Commonwealth System of Higher EducationInventor: Thomas J.

Patent number: 5248585Abstract: This invention relates to novel radiation sensitive compositions. More particularly the invention relates to photoresists containing phosphorus and nitrogen linked polymers; i.e., polyphosphazenes, useful in the preparation of a relief pattern on a substrate; e.g., a silicon wafer or aluminum plate. The polyphosphazenes of in this invention can be synthesized by the condensation of N-trimethylsilylalkoxyphosphorimides. Radiation sensitive positive photoresist compositions of the invention can be developed in aqueous base developer or organic solvent developer The base developer dissolution properties of the composition can be controlled by incorporating carboxylate groups into the polyphosphazene. The polyphosphazenes utilized in this invention have good solubility properties in various organic solvents and also have good mechanical, electrical, adhesion and thermal properties.Type: GrantFiled: December 18, 1991Date of Patent: September 28, 1993Assignee: Hoechst Celanese CorporationInventors: Thomas J.

Patent number: 4462168Abstract: A drafting tool functioning as a variable angle straight edge comprises an elongated rectangular main body portion made of transparent material. The lower edge of this main body portion has a first straight edge extending a major portion of the length of the main body portion from one end toward the other end to terminate at a point between the two ends. This edge is spaced a first distance from the top edge of the tool. A second straight edge parallel to the top edge and the first straight edge extends from the other end of the tool toward the termination point and is spaced a greater distance from the top edge than is the spacing between the top edge and the first straight edge. The two edges are interconnected by an offset forming a notch to receive the point of a drafting instrument at the junction of the offset and the first straight edge.Type: GrantFiled: June 27, 1983Date of Patent: July 31, 1984Assignee: International Design CorporationInventors: Thomas J.

Patent number: 4289863Abstract: Novel catalysts are provided for the polymerization of olefins such as ethylene. The catalysts consist essentially of a chromium compound supported upon an inorganic carrier containing aluminum and phosphorus moieties, at least a portion of the chromium having a valence of less than 6. The inorganic carrier is an amorphous precipitate of aluminum phosphate or an amorphous precipitate containing aluminum and phosphorus moieties in an atomic ratio in the range of about 5:1 to 1:1. The catalysts are particularly useful for polymerizing ethylene in a Particle Form Process in that the catalyst has essentially no polymerization induction period and provides ethylene polymers having a desirably broad molecular weight distribution and a desirably high melt flow shear ratio.Type: GrantFiled: April 4, 1980Date of Patent: September 15, 1981Assignee: Gulf Oil CorporationInventors: Robert W.
