Abstract: A catheter for retrograde orientation in a blood flow is used to determine the blood flow rate by thermodilution measurements. The determination of the blood flow rate accommodates injectate induced thermal influences on a dilution thermal sensor, wherein the thermal influences can occur prior to introduction of the injectate into the blood flow.

Abstract: A method for fabricating electrically conductive silicon carbide articles by doping and sintering submicron silicon carbide particles using sub-micron alumina as the dopant source. Submicron alumina particles are made by milling aluminum powder. Despite the ductility of metallic aluminum, it is successfully ball milled in an aqueous medium through the creation and abrasion of successive layers of an alumina skin to yield alumina particles as small as 0.01 &mgr;m across. When suitably composed mixtures of the silicon carbide and alumina are molded into a green body and heated sufficiently in a non-oxidizing furnace atmosphere, the alumina breaks down to metallic aluminum which diffuses into the silicon carbide. The small particle sizes and the presence of a sintering aid enable rapid processing kinetics which favor saturation of the silicon carbide by the aluminum and inhibit grain growth.

Abstract: A system for handling effluent from a film processor. A transportable holding tank is attached to the film processor using quick-disconnect fittings, and accepts effluent discharged from the film processor by gravity. The holding tank is uncoupled from the film processor and coupled to a receiving station with quick-disconnect fittings similar to those on the film processor. The effluent is pumped into the receiving station. The system is designed to minimize exposure to film processing chemicals, and handles parallel segregated streams of silver-bearing and non silver-bearing effluent.

Abstract: A method for monitoring the condition of an inkjet printhead. A test image is printed by the printhead and a second reference printhead. The density of ink dots in the test image is selected so that each dot just contacts adjacent dots while avoiding significant overlap. A defective nozzle can produce misplaced or undersized dots, creating abnormal spacing between adjacent dots. At the selected ink dot density, the abnormal spacing is most perceptible to the eye.

Abstract: A low profile transportable holding tank for accepting waste from portable toilets. The holding tank is carried on a flatbed vehicle and has a flat deck for cargo, thus effectively increasing the cargo-carrying capacity of the vehicle compared with that available if the vehicle were carrying a conventional holding tank. Internal reinforcement enables the holding tank to withstand a partial vacuum imposed for pumping waste into the tank.

Abstract: A shoe including an upper, a mid sole permanently attached thereto, and an outer sole releasably engaged with the mid sole. The outer sole and mid sole are secured together by a fastener and by a retaining lip. The fastener can be disposed in a capture position wherein the spaced apart lip precludes separation of the mid sole and outer sole. Upon disposing the fastener in a release position, the mid sole can be separated from the outer sole.

Abstract: A combination model train sensor and block signal includes a train proximity sensor, a red signal light, a green signal light, and a controller connected to the proximity sensor and the red and green signal lights and the controller turns on the green signal light and turns off the red signal light when the proximity sensor indicates the absence of a train, and turns on the red signal light and turning off the green signal light when the train proximity sensor indicates the presence of a train. A light source, preferably an infrared light source, and a light detector, preferably an infrared light detector, are arranged to reflect and detect from a passing train to indicate its presence. An output connected to the train proximity sensor for producing an output signal when the sensor indicates the presence of a train, which output can be used for controlling a remote block signal.

Abstract: An apparatus for assessing the operation of a machine as used by an operator with a given tool is disclosed. The present system includes a unique tracking tag associated with a given tool. An input device monitors use of the tool along with a given operator, wherein a cycle counter monitors use of the tool by the operator for an elapsed time. A processor/controller is employed to generate corresponding reports.

Abstract: The invention relates to a fuselage Pitot-static tube comprising three groups of orifices for determining the total pressure (2), static pressure (3) and angle of attack (6, 7), and an axisymmetric body (1) and strut (5) for mounting an anti-icing system having, arranged between them, airways (10) and electric heating elements (8). The orifices for determining the angle of attack are arranged on the strut, whose cross section is constructed in the form of a subsonic aerodynamic profile with a rounded-off nose or a tapered nose, and are arranged between the nose of the profile and the position of its maximum thickness.

Abstract: An electric shaver, and in particular an electric shaver wherein are included blades which while rotating around their own centers also orbit around another axis, thus providing that the blades sweep a large area.

Abstract: A low pressure foaming nozzle assembly having a modular construction for permitting the ready interchange of nozzle tips. The foaming nozzle assembly may be constructed of two pieces, with a first configuration employing a flow body and an engaging nozzle tip and a second configuration employing a pair of mating halves, wherein each mating half includes a portion of a venturi, a throat and a nozzle tip. The assembly cooperatively engages a foaming liquid source such as a wand, and upon pressure on the foaming liquid source, a foam is generated.

Abstract: A flat flexible and imperforate mirror which is conveniently designed and sized to fit anywhere a credit card can be stored is disclosed. The mirror has a substantially flat rectangular body, a front reflective layer and rounded edges. An indicia bearing layer is applied to the opposite side of the body from the reflective layer.

Abstract: A method and apparatus for monitoring and measuring the filter blood volume by dilution techniques in real time, wherein the filter may be in use or off line during the measurements. The system includes a method and apparatus for measuring or monitoring the volume of a blood side of a filter by employing one of a bolus in the blood side upstream of the filter; a change of the filtration rate in the filter; and a bolus on the dialysate side, wherein the filter blood volume is calculated from the obtained data.

Abstract: A conductive gasket for use in apparatus to block the exit or entry of electromagnetic interference (EMI) between adjacent metal surfaces of the apparatus. The gasket is formed at least in part by a polymeric film having an outward facing surface embossed so as to provide a plurality of peaks distributed over the surface. A metal is coated, by vapor deposition, onto the surface so as to over lie the peaks. This provides the film with a conductive surface. When located between adjacent metal surfaces, abrasion of the metal coating from the peaks over time does not adversely affect the conductive properties of the film surface. This is because the wearing away of the metal from the tops of the peaks exposes a cross section of the metal at the sides of the peaks, which remain in contact with the adjacent metal surfaces of the apparatus.

Abstract: A method for securing a counterweight guiding system in performance rigging in places of entertainment. An elongate guide rail has a cross-section which interlocks with a clip, the clip extending transversely beyond the guide. The guide rail is secured to a support by fastening the clip to the support, the guide itself not requiring any specific fastening points.

Abstract: An apparatus for forming transitioned edges in patterns formed by a scanning laser in a dyed textile material is disclosed. The transition rate between the untreated material and the treated material is controlled by passing a scanning laser beam through a mask prior to the laser beam reaching a focal point. An apertured mask can be employed to control the transition rate, wherein the location of the aperture relative to the focal point of the laser beam and configuration of the aperture periphery are manipulated to effect the transition rate.
