Abstract:
A circuit includes a first source for providing an alternating electric field, a directional circuit connected to the first source for providing an alternating electric field by a transmission conductor there being no conductive return path provided back from the directional circuit to the first source for providing an alternating electric field. The directional circuit being a loop circuit which includes one or more circuit elements causing the loop circuit to be asymmetric to current flow; the directional circuit having no continuous connective path to earth ground, or battery ground, the directional circuit thereby developing a DC potential in response to the alternating electric field which is self referencing between a relatively high potential output and a relatively lower potential output. One or more loads connected to the directional circuit, the one or more loads also not having a continuous conductive path to earth ground or a battery ground. The load is not provided with a continuous connection to earth ground, or battery ground.
Abstract:
An AC LED package and circuits are disclosed along with an AC LED driver. The AC LED circuit may include as few as one LED or an array of anti-parallel LEDs driven with AC power sources and AC LED drivers at various voltages and frequencies. The AC LEDs are pre-packaged in various forms and materials and designed for mains or high frequency coupling in various forms to AC power sources, inverter type drivers or packages. The AC LED driver is a fixed frequency driver that provides a relatively constant voltage output to different size loads within the wattage limitation of the driver and in some cases is a direct mains power source.

Abstract:
Apparatus of use in the collection and storage of hockey pucks from an ice surface, the apparatus having a storage facility, such as a bag having a puck entry aperture; aperture door adjacent the entry aperture wherein the door is (i) in a static position as to prevent stored pucks in the bag from exiting through the entry aperture, and (ii) operably displaceable by a moving puck to allow entry of the puck into the bag through the entry aperture and wherein the door is returnable to the static position after passage of the puck into the bag; and handle means connected to the bag by which the apparatus may be moved along on or lifted from the ice surface. The apparatus provides improved convenience to a person in picking up hockey pucks from the ice surface.
Abstract:
A wheel centering pin 15 disclosed for vehicle wheels having apertures of uniform diameter. The wheel centering pin is provided as a set of three that are threaded on three circumferentially spaced hub bolts on which a wheel is mounted to center the wheel. Nuts are threaded on the remaining bolts and tightened to fasten the wheel to the hub. The centering pins are removed, and remaining nuts are applied in their place and tightened on the remaining bolts to center the wheel.
Abstract:
Improved processing of an oxygenate-containing feedstock for increased production or yield of light olefins, particularly for increased relative yield of propylene is provided. Such processing involves oxygenate conversion to olefins and subsequent oxygenate conversion effluent stream treatment including isomerization of at least a portion of the 1-butenes to 2-butenes and metathesization of at least a portion of the 2-butenes to produce additional propylene.
