Abstract: A multilumen catheter assembly and methods for making and inserting the same are provided. The catheter assembly includes a unitary catheter and at least two distal end tubes which extend distally from the unitary catheter. The at least two lumens in the unitary catheter are in fluid communication with passageways through the distal end tubes. The catheter assembly may be made by extruding a unitary catheter tube having internal longitudinally extending lumens, then splitting the tube on its distal end portion to form distal end tubes. The tubes are then ground and polished to form a smooth surface on the exterior of the tubes. The catheter assembly may also be made by forming an outer layer on at least two longitudinally extending catheters while leaving two distally extending portions of the tubes outside the outer layer to form the distal end tubes.

Abstract: A textile made at least in part with conductive yarns for the purpose of generating heat from an electrical power source. The textile has conducting yarns, or “heaters”, with conductivity and spacing tailored to the electrical source to be used and the heat to be generated. The heater yarns have a positive temperature coefficient whereby the resistance of the yarn increases with an increase in temperature and decreases with a decrease in temperature. “Leads”, such as conductive yarns, can be used to supply electricity to the heater yarns. A coating to the textile can electrically insulate the textile as well as provide protection to the textile during activities such as laundering or use.

Abstract: A surface heating device comprises a heating element fabricated by braiding plural conductors on a flexible supporter. The surface heating device employs a heating element member which is reduced in thickness or diameter, and thus can be inhibited from providing an uncomfortable touch when sat upon or appearing as a relief on a surface cover of a seat. Also, because a pad is reduced in thickness, the surface cover of the seat can be heated up rapidly. The heating element is fabricated by braiding the conductors, and thus, when loaded with a weight when sat upon, the heating element allows a resultant stress exerted thereon to be dispersed through the conductors, hence being stronger against bending. Moreover, the conductors are inhibited from separating from each other and need no insulating coat.

Abstract: A heating jacket for use on a processing vessel includes a flexible heater jacket having a plurality of layers, a flexible heating element positioned within the layers, and a thermostat positioned within the layers and electrically connected to the heating element for regulating the heating element. An access opening is formed in at least one of the layers to provide access to the thermostat positioned within the layers. An access cover includes a pivotable inner cover which selectively covers the access opening and an outer cover which selectively covers the inner cover. A mounting bracket of the thermostat extends below a pair of parallel flexible strips to secure the thermostat to the layers whereby the thermostat is readily replaceable in the field.

Abstract: A method of lengthening the useful life of heating elements that are formed essentially from molybdenum silicide and molybdenum tungsten silicide and different alloys of those basic materials, at times when the elements are operated at a relatively low temperature, such as a temperature in the range of 400-800° C. The gaseous atmosphere surrounding the elements as they operate has a water content that is less than about one percent by volume.

Abstract: Systems and methods are provided for delivering solid precursors in deposition processes. A flow monitor is used to measure and regulate the flow of vaporized solid precursor material from a vaporization chamber to a deposition chamber. The flow monitor chokes the supply of vapor into deposition chamber to regulate vapor flow. To avoid condensation of the solid precursor material in the delivery lines or flow monitor, a controller is placed in a feed back loop to monitor the flow rate make adjustments to the amount of vapor available at the inlet of the flow monitor.

Abstract: A multilumen catheter assembly is provided, which includes a unitary portion and at least two distal end tubes extending distally from the unitary portion. The unitary portion includes an exterior having a generally round or oval shape in cross section and includes at least two distal end tubes of generally circular (or other) cross sectional shape extending longitudinally therethrough. The catheter assembly may be made by extruding a unitary tube having internal longitudinally extending lumens (of circular or other shape), then splitting the tube on its distal end portion to form distal end tubes. The tubes are then ground and polished, the finished tubes retaining in combination the generally oval cross sectional shape of the unitary extrusion, or the finished tubes can each be finished to a circular, or other, cross sectional shape, or the finished tubes could include a combination of cross sectional shapes over its longitudinal length.

Abstract: A muffler of a compressor in which an imaginary central line of flowing direction in a passage pipe at an inlet side and an imaginary central line of the flowing direction in a passage pipe at an outlet side are formed to have an angle of 40˜50° or a curved surface having a certain curvature is formed in an extended space between an outlet end of the passage pipe at the inlet side and an outlet end of the passage pipe at the outlet side. Accordingly, the refrigerant gas which flows to the passage pipe at the outlet side through the passage pipe at the inlet side can flow smoothly as the refrigerant gas passes the curved surface and by attenuating pulsation flow between the passage pipes at the inlet side and outlet side, the refrigerant gas can be sucked smoothly. Therefore, suction amount of the refrigerant gas increases, thus to improve the efficiency of the compressor.

Abstract: The present invention is directed toward an improved method and apparatus for securing a prosthesis that is being implanted in a patient. A heat-curable bone cement is used to secure the implanted prosthesis in the patient. A heater is then applied to the prosthesis to decrease the time required for the cement in contact with the prosthesis to cure or set. An adjustable heater control and temperature gauge are used to monitor and control the amount of heat applied to the prosthesis. A socket is provided on the heater such that a tip designed to couple with the particular type of prosthesis being implanted in the patient can be installed on the heater. One or more safety gauges are used to monitor the heater's operation to insure that an excessive amount of heat is not being applied.
