Abstract: A resin layer, having a generally planar form and having a first outer face and an essentially parallel second outer face, and supported on its first outer face by a supporting structure, parallel to and in contact with the first outer face, wherein the layer comprises a skeletal structure embedded within the resin, the skeletal structure comprising: a plurality of studs distributed throughout the plane of the layer, each stud having a length in the direction perpendicular to the plane of the layer, and terminating in a first end and a second end, the studs having a length extending from at least the first face to at least the second face; and a framework of solid connections, connecting each solid stud to a plurality of adjacent studs, particularly for use as part of a prepreg.

Abstract: A downhole tool for dampening vibrational, lateral, compressive, and tensile forces exerted on sensor equipment inside a drillstring is described. The downhole tool is housed inside the drill string. The tool generally includes a bottom end shaft for connection to the drillstring and that is telescopically engaged within a compression housing and a torsional housing. The torsional housing enables the bottom end shaft to slide axially with respect to the torsional housing whilst preventing torsional movement of the bottom end shaft relative to the torsional housing. The compression housing is connected to the sensor equipment and operatively contains a first spring between the compression housing and the bottom end shaft that absorbs compression forces between bottom end shaft and compression housing.

Abstract: A system and method for use in matching a source to a dynamic impedance electrical load is described. The system may include a processor that controls a signal generator to sweep across a frequency spectrum to locate a resonant frequency of the dynamic impedance load. The determination of resonant frequency may be made based on sensing the power consumption of the amplifier supplying the load and locating the frequency at which the power consumption is minimized. Periodically tracking and adjustment of the frequency to maintain a minimum power consumption may be automatically performed. The load may be a SAW atomizer.

Abstract: A bicycle side chair apparatus includes a frame assembly that further includes a base having a front edge, a rear edge, a first side edge and a second side edge. A seat assembly is attached to and extends upwardly from the base. A wheel is rotatably coupled to the base. The wheel is positioned adjacent to the second side edge. A front bracket is attached to the frame assembly and is configured to removably secure the frame assembly to a bicycle frame between a seat and a pair of handlebars of the bicycle. A rear bracket is attached to the frame assembly and is configured to removably secure the frame assembly to the bicycle frame adjacent to a seat of the bicycle.

Abstract: Apparatus for filtering entrained particulate matter from a gaseous fuel embodies an upstanding housing having a hopper adjacent its lower end for receiving dislodged particulate matter. At least one upstanding, porous tubular filter bag is mounted within the housing. The ends of the filter bag are attached to the housing with its length being greater than the distance between the points of attachment of the ends to the housing. An inlet communicates with one end of the filter bag for introducing a gaseous fluid with particulate matter entrained therein. Particulate matter carried by the gaseous fluid is deposited on the inner surface of the filter bag with cleaned gaseous fluid passing therethrough. An outlet communicates with the housing and discharges the cleaned gaseous fluid.
