Abstract: A method and system for a preheating step of a wave soldering process. A bottom side preheater is positioned underneath a PCB and a thermal carrier is positioned adjacent the PCB. A top side heater may also be used. The PCB includes one or more through holes, and an electronic component having one or more pins is mounted on the PCB so that each pin is positioned in a corresponding through hole. The bottom side preheater directs heat to the bottom surface of the PCB, thereby heating the bottom surface via heat convection. The thermal carrier directs heated air laterally across the top surface of the PCB to increase a heat transfer at the top surface without increasing the temperature of the electronic component, thereby reducing a temperature differential between the top and bottom surfaces.

Abstract: Apparatus and methods for removing components soldered to a printed circuit board (PCB). Embodiments presented generally include a contact plate having a component specific platform offset from the contact plate body. The offset platform may be substantially identical in size and shape as the component to be removed. Accordingly, contact between a heated platform and component may allow for conductive heating to occur based on contact with the component. Thus, forced air or convective heating of the component does not occur such that solder joint defects in adjacent components may be prevented. A vacuum retention port may be provided at an interface of the platform and component when in contact. The vacuum retention port may allow the freed component to be removed from the PCB using vacuum to hold the freed component to the platform. Also, apparatus for automation of a process according to the forgoing are presented.

Abstract: The invention relates to a method for determining the presence of renal damage in an individual and also to a method for detecting one or several proteins selected from the list comprising Reg3B, fetuin B, Ras-related GTP-binding protein A serine protease inhibitor A3L, subunit 1 of COP9, gamma subunit of ATP synthase, gelsolin, ribonuclease UK114, aminoacylase 1A, alpha-enolase, keratin 5, parvalbumin alpha, ribonuclease 4 or serine protease inhibitor A3K. The renal damage may be acute renal failure. Said renal pathologies may be caused by the administration of a nephrotoxic agent, wherein the nephrotoxic agent may be an aminoglycoside antibiotic such as gentamicin, or cisplatin. The invention also provides means to differentiate the renal damage or renal failure induced by gentamicin from that induced by cisplatin, through the biochemical analysis of the urinary level of Reg3B and/or gelsolin, or fragments thereof.

Abstract: Summarizing, we may say that this invention involves a stopper for bottles of beverages in general, particularly for wine, champagne, cider, sodas, and the like, which comprises: a metallic cap with internal plastic plastering (liner) so as to attain airtight closure and a “twist-off” system or the like with screwed threads that enables a quick opening of the bottle; a plastic cube of adequate hardness, with negative impressions or locks that hold and coincide with the external locks in the metallic cap, and the external diameter of which has a number of vertical grooves that allow for an anti-turn locking mechanism when it is placed inside an external aluminum cover; an external aluminum cover, the internal diameter of which locks with the outside of the referred plastic cube, in a cylinder-like and closed manner on one end on which are set the two parts mentioned above.

Abstract: An apparatus is provided for determining the mass flow rate of a fluid using thermal means. The apparatus utilizes resistance temperature detectors having substantially linear temperature dependencies to determine the mass flow rate of a fluid. The apparatus maintains a constant ratio between resistances of the first and second resistance temperature detectors, the amount of current necessary to maintain the constant ratio corresponding to the mass flow rate of the fluid. The apparatus includes a microprocessor wherein an algorithm relating the current and mass flow rate including thermophysical properties of the fluid, sensor thermal resistance, and probe stem loss information provides the fluid mass flow rate based upon calibration information. Operation in alternate fluids without the need for recalibration is possible utilizing calibration constants obtained in the primary fluid and substitution of thermophysical properties and stem loss characteristics of each fluid in which operation is desired.

Abstract: Differential outputs produced by twin thermoresistive sensors are used to determine the level and flow of a medium. Separate constant current sources supply power to each sensor so that one constant current source supplies sufficient current to cause significant self-heating of the sensor (hot sensor) and the other constant current source supplies relatively little current with insignificant self-heating of its corresponding sensor (cold sensor). Resistive changes in the sensors produced by level and flow changes of the medium produce measurable voltage changes, thereby providing a convenient parameter by which to determine level or flow. Level or flow is determined by dividing the difference in the voltages across the hot and cold sensors by the voltage across the cold sensor.

Abstract: A thermoresistive sensor system compensates for ambient temperature of a medium. First and second side-by-side sensors are mounted in the medium, each having a resistance that varies with temperature change in the medium. A thermal compensation control circuit supplies current to the first sensor such that the cube of its current times its resistance (I.sub.1.sup.3 .times.R.sub.1) is constant. The control circuit supplies current to the second sensor at a multiple of the current through the first sensor. A signal based upon the voltages across each sensor is produced as a temperature compensated output. In this manner, the system automatically compensates for temperature changes in the medium which would otherwise degrade the accuracy of the output.
