Abstract: The present invention provides a moulding material (100) comprising at least one dry fibrous reinforcement layer (102, 103) having a surface resin material (106) conjoined to a first surface thereo and a structural resin material (101) conjoined to a second surface thereof wherein the structural resin material is provided with a recess (107) which is free from resin and is located at the edge of the structural resin layer (101) and wherein the dry fibrous reinforcement layer (102, 103) provides a venting structure to allow entrapped air to pass out during processing. The material of the present invention can be used to form a composite which can be used as surface coating for large components such as wind turbines.

Abstract: A shock absorbing handlebar brace attached between handlebar sides. The shock absorbing handlebar brace includes a telescoping center section with a compressible rubber insert to allow the brace to slightly extend upon impacts to reduce rider fatigue.

Abstract: An erosion shield for an aircraft window includes an annular band having a radially outer brim and a radially inner clip. The shield is sized to cover a composite window frame having an outer rim and an inner sash around a central aperture in which is mounted a window pane. The clip is asymmetrical around the central aperture to protect the sash and permit assembly of the shield thereto.

Abstract: A treadmill is provided that has a treadmill drive motor carriage that can pivot relative to a frame of the treadmill such that the incline of the treadmill can be controlled while the carriage can be moved to a position that permits upright storage of the treadmill on the carriage. This arrangement advantageously permits a walk through treadmill design to be used that can be stored uprightly. The treadmill can be equipped with a console and stanchion that can be folded against the deck of the treadmill. One incline arrangement pivots the carriage using an incline drive carried by the carriage that engages a gear grounded to the treadmill frame. Another preferred incline arrangement uses a four bar linkage movable carried by the frame that is driven by a linear actuator to pivot the carriage.

Abstract: A semiconductor material which has a high carbon dopant concentration includes gallium, indium, arsenic and nitrogen. The disclosed semiconductor materials have a low sheet resistivity because of the high carbon dopant concentrations obtained. The material can be the base layer of gallium arsenide-based heterojunction bipolar transistors and can be lattice-matched to gallium arsenide emitter and/or collector layers by controlling concentrations of indium and nitrogen in the base layer. The base layer can have a graded band gap that is formed by changing the flow rates during deposition of III and V additive elements employed to reduce band gap relative to different III-V elements that represent the bulk of the layer. The flow rates of the III and V additive elements maintain an essentially constant doping-mobility product value during deposition and can be regulated to obtain pre-selected base-emitter voltages at junctions within a resulting transistor.

Abstract: A transducer assembly adapted for the pulse-emission of a signal includes a transducer (10) with a drive-circuit (20) therefor. The drive circuit (20) includes a charge-storage device (21), a wound-coil device (23) and one or more switching-elements (24, 25). The assembly can be used to determine the level of a fluid in an enclosed vessel.
