Abstract: A method and apparatus for a pump control system. One or more embodiments of the invention include a pump controller that can perform a self-calibrating procedure, can provide precise motor speed control, can provide a limp mode before shutting down the motor when system parameters are exceeded and/or fault conditions occur, can detect fault conditions, and can store fault conditions for later retrieval.

Abstract: Embodiments of the invention provide a control system for a garage door. The control system can include a motor, a pulley, a synchronous drive member, a carriage, and an operator. The pulley can be coupled to and driven by the motor. The synchronous drive member can be coupled to the pulley and driven by the pulley. The carriage can be coupled to the synchronous drive member and to a bottom edge of a garage door. The operator can be coupled to the motor and can control the motor. The operator can be mounted vertically adjacent to the garage door when the garage door is in a closed position.

Abstract: A backup valve for use with a pool cleaner coupled to a source of water under pressure. The valve includes a housing having an inlet and at least a first outlet and a second outlet. The valve further includes a timing apparatus directing water from said inlet to the first outlet or the second outlet. In addition, an adjustable flow controller over the second outlet is provided to increase the flow speed of fluid exiting the outlet.

Abstract: An adjustable hose clip is provided for use with a pool cleaner debris bag, including a first member having a retaining arm and a second member having a retaining arm. The hose clip also includes means for connecting the hose clip to a pool cleaner debris bag and resilient means for resiliently biasing the retaining arms towards each other such that at least a portion of a pool hose can be retained between the retaining arms. In one example, the resilient means is adapted to automatically adjust the distance between the retaining arms to accommodate various pool hoses having various diameters within the range of a minimum diameter to a maximum diameter at least 50% larger than the minimum diameter. In addition or alternatively, an arrangement for cleaning a swimming pool can include an automatic pool cleaner, a debris bag, a hose and an adjustable hose clip.

Abstract: An enclosure assembly includes a first enclosure unit including a first door, a second enclosure unit, and a handle coupled to the second enclosure unit, the handle being operative so as to turn on or turn off power to the first enclosure unit, and wherein the first enclosure unit and the second enclosure unit are configured such that the first door cannot be opened if the handle has not been turned to a power-off position.

Abstract: Apparatus and methods are provided for eliminating axial porosity accompanied by impurity segregation arising at bulk crystallization of the axial zone of the liquid core of a continuous ingot.

Abstract: A method and apparatus for measuring the concentration of gas, such as hydrogen, in a liquid, such as molten aluminum, without requiring a bias or adjustment to compensate for variations in ambient conditions, such as humidity. A measurement system includes a probe connected to an analyzer with a housing enclosing a pump assembly. The measurement system may include a climate-controlled environment substantially devoid of ambient humidity and surrounding at least the pump assembly. A modified pump assembly includes at least one seal, at least one diaphragm and at least one gasket made from a material compatible with hydrogen and substantially unaffected by ambient humidity. A method of use is also disclosed.

Abstract: Cylinder head assemblies including a cylinder head and a piston are disclosed. The cylinder head includes: a recessed valve region including a first and second bulbous portion connected by a waist, the first bulbous portion accommodating an intake valve and the second bulbous portion accommodating an exhaust valve; an intake port passageway having a gradually contoured flowpath between an intake port and the intake valve in the valve region; and an exhaust port passageway having a gradually contoured flowpath between an exhaust port and the exhaust valve in the valve region. The piston includes a recessed region that substantially conforms to the recessed valve region of the cylinder head. Related overhaul kits and methods of making improved cylinder head assemblies are further disclosed.

Abstract: A method of stabilizing an arc between electrode tips in a high pressure arc discharge lamp is provided comprising initially creating an arc between the pair of electrodes during a start-up phase of the lamp by supplying power to the lamp for a first period. The method then transitions the arc to attach itself between the tips of the electrodes by removing the power supplied to the lamp for a second period and then resupplying power to the lamp after completion of the second period. The first and second periods for respectively initially supplying and removing power are preferably selected based on either an elapsed period of time, the measured operating lamp voltage, or the measured lamp pressure. Once the arc becomes attached to the tips of the electrodes in this manner, the arc will remain stabilized between the electrode tips during operation of the discharge lamp.

Abstract: The present invention relates to a moisture proof resealable non-cylindrical container and cap assembly for consumer packaging including candy, tobacco products, pharmaceutical products, electronic products, such as nard drives or circuit boards and coffee samples. The moisture proof resealable non-cylindrical container may be made of plastics, such as polypropylene and polyethylene. In addition, the non-cylindrical container has a cap, which includes a thumb tab to facilitate the opening and closing of the container.

Abstract: The embodiments of the invention are directed to a new apparatus and method of measuring the water content using time domain reflectometry (TDR), or electrical conductivity in deep soil levels to. The method uses flat, flexible, waveguides attached to a flexible sleeve filled with a filling material which press the flexible waveguides against an irregularly shaped interior borehole wall.
