摘要： The present invention provides a hydraulic powered wheelchair pivotable from a sitting position to a standing position with minimal user effort. The pivoting frame assembly includes a rigid horizontally arranged wheel support structure, a single vertical extending member secured to the wheel support structure and centered between the wheels, and a pivoting frame linkage assembly pivotably connected at the upper end of the vertically extending member. A hydraulic jack rests on the wheel support structurs, and is connected at the other end to the seat support members of the pivoting assembly. A user of the wheelchair pivots a lever assembly to raise the jack, and thus raise the chair to the standing position. An electric buzzer system is integrated with the wheelchair, and an alarm informs the operator when the chair has reached the standing position.

摘要： A refrigerant gas leak detector for detecting the location of leaks of refrigerant gas such as halogen has a sensing tip with a pair of electrodes across which a relatively high voltage is generated to cause a corona current to pass through the electrodes. The voltage applied across the electrodes is varied to maintain the corona current through the electrodes at a substantially constant magnitude. The leak detector includes a gas sensing circuit that detects changes in the concentration of refrigerant gas by sensing the voltage applied to the electrodes. The sensitivity of the gas sensing circuit is automatically varied based on the concentration of refrigerant gas present. The leak detector includes a signal generating circuit that causes a number of audible and visual indications to be generated based on the concentration of refrigerant gas sensed as well as other operating conditions. The leak detector also has a circuit for detecting the presence of an abnormal operating condition, which is assumed to occur when the corona current falls below its substantially constant magnitude.

摘要： Apparatus and methods for detecting the presence of an airborne chemical or biological analyte utilize: a substantially gas- and liquid-impermeable container; means for introducing a substantially analyte-free collection liquid into said container; means for rapidly sampling ambient air and transferring said analyte therefrom into said collection liquid, said sampling means comprising an air intake means and and an air venting means; and means for removing from said container an analyte-enriched collection liquid; wherein said volume of air passes through a substantially horizontal air inlet and downward through a substantially vertical collector electrode tube with means for applying an electric field between said tube and a co-axial spiked wire- or rod-shaped discharge electrode. Efficient wet electrostatic precipitation with efficient collection of captured particles into a tiny liquid volume are achieved by the use of a liquid flow system comprising a programmable reversible pump with a reversible filter and appropriate liquid connections and valves. Injection of water sprays into the air stream and onto the interior walls of the collector electrode permits thorough wetting of interior surfaces and efficient removal of residual captured particles.

The flow passage has a first bore provided between the gas inlet and the second end of said conductive housing and a second bore having a diameter smaller than that of the first bore. The second bore is provided between the first bore and the gas inlet of the conductive housing and abuts the first bore to form an edge in the interior of the housing. The flow passage also has a third bore of a diameter smaller than that of the second bore provided between the second bore and the gas inlet. The gas leak detector also includes a second electrode provided in the interior of the conductive housing. The second electrode has a tip provided at a defined location with respect to the edge in the interior of said housing. The leak detector also has a voltage supply circuit for generating a voltage sufficient to cause a corona to be formed across the electrodes, with the corona being formed between the second electrode and the edge in the interior of the housing.
