A wave energy conversion device whereby its structural design and positioning converts oscillating wave energy into unidirectional wave induced water flow. A judiciously placed upper closed perimeter boundary positioned on a submerged horizontally oriented surface pierced with an opening, focuses incident waves inward creating a resonant wave condition where the superposition of waves induces a predominantly downward unidirectional flow through the opening. A segmented sealed upper boundary results in the additional storage of water head due to the overtopping of waves, thus further smoothening and increasing the magnitude of the unidirectional flow. This wave energy converter can be utilized with unidirectional hydro turbines for electrical power generation.

A removable wavemaker having a self-supporting structure for use in a wave tank has an integrated mounting structure for mounting on a frame of an open top of the wave tank, a linear motor positioned above a waterline in the wave tank having a forcer containing activation coils that is driven in reciprocation motion by electromagnetic interaction with an array of permanent magnets contained in a tubular support structure on which the forcer is configured to slide, and a vertically-oriented wave board mounted on a lower part of the integrated mounting structure below the waterline for generating waves within the wave tank. The forcer is supported on a movable carriage that rides on a rail fixed to the integrated mounting structure and is coupled to the wave board.

A ground cover for use as a containment barrier including a geomembrane sheet and a geotextile sheet bonded together by an adhesive layer positioned therebetween. The adhesive layer does not fully cure, remains tacky and has an adhesive strength sufficient to maintain a bond between the geomembrane sheet and the geotextile sheet under normal foot traffic and a release point allowing separation of the geomembrane sheet and the geotextile sheet under shear forces generated by heavier traffic.

A bidirectional axial flow turbine with self-pivoting blades is provided for use in a central opening of submerged horizontally-aligned structure forming a wave energy conversion device. Entry and exit inner guide vanes are positioned on opposite sides of the vertically-aligned central opening, for directing the bidirectional fluid flow into and out of the central opening and inducing a vortex swirl in both directions of fluid flow that has the same direction of rotation. Within the opening, a turbine hub is mounted with a plurality of uniformly spaced self-pivoting blades that have a symmetrical blade profile to the bidirectional flow. The self-pivoting blades automatically change their blade angle in response to the force of water flow on the blades, so that they turn the turbine shaft in the same rotational direction in both flow directions.

A wave energy conversion device that employs a submerged horizontally-aligned structure provided with a central opening formed in a horizontally extending surface, focuses wave induced water-particle motion, resulting in a flow into and away from the central opening, and a turbine is mounted in the central opening to be driven by this flow of water. Preferably the operation of this device occurs in a structural submerged depth of less than one-half wavelength of waves in the region. In a preferred embodiment, the flow through the central opening is bidirectional, and a self-rectifying turbine is used for unidirectional rotation. In an alternative embodiment, unidirectional check valves are used to direct water flow to a unidirectional turbine. Guide vanes are used to direct the flow inward towards the opening and can also be used to induce swirl in the flow field. When constructed axisymmetrically, the device can generate power from waves coming from any direction. The device may have multiple turbines arranged within it, or multiple units can be built into an array for power generation. The device may be mounted on supports fixed to the sea floor for shallow-water applications, or may be a floating submerged structure moored to the ocean floor for deep-water applications.

Methods for specific RNA capture, detection and quantification are presented utilizing a protein that selectively binds RNA:DNA hybrids, preferably an RNase H that is modified to reduce degradation of the nucleic acid molecules and enhance specific detection of mixed RNA:DNA nucleic acid hybrids. Labeling of the RNA and/or amplification is not required to perform these methods. Modified RNase H enzymes useful in such methods are disclosed.

A method for attaching a clutch pedal assembly to a vehicle with a brake pedal assembly for a manual transmission conversion from an automatic transmission application including extension of a brake support shaft laterally from an existing brake pedal assembly and through a clutch pedal supporting bushing and then further outward into engagement with a wall of the vehicle. Specifically, the outward end of the support shaft is insertably extended through a hole in the wall of the vehicle for supporting that end portion of the shaft. The method further includes utilizing a metal cutting edge or tip on the outward end of the support shaft such that rotation of the support shaft can drill the support hole in the vehicle wall.

A clip mechanism for a line utilizing a first member having a first portion and a connected second portion. A second member with first and second portions connected to one another is also employed. The second member also possesses an end portion terminating in a plurality of protrusions. Each of the protrusions possesses a tip. The tips extend from the second member at different lengths such that at least, one tip lies closer to the first portion of the second member than another tip. In certain cases, the ends of the tips lie in an arcuate configuration that is particularly useful for gripping rounded lines.

A heated blade arrangement in a press is brought down on a plastic work piece of heavy corrugated plastic held on the bed of the press to compress the work piece along fold lines. The work piece may then be folded up to form a box-like structure. The arrangement includes heaters to heat surfaces of the work piece to be pressed together for adhesion. A frame is provided, about which the box-like structure may be formed.

A device for holding an endotracheal tube at a corner of a human patient's mouth to allow the mouth to remain free of obstruction in event aspiration of stomach contents occurs. The device includes a relatively stiff clamp holder pad. The clamp holder pad has a clamp holder mounted at one end thereof. A clamp for holding an endotracheal tube at one side of a person's mouth to leave a central area of a person's mouth between its corners free of obstructions to enable regurgitated foods and fluids to flow more freely from a person's mouth is provided. The clamp holder having a releasable fastener securing the clamp to the clamp holder. Straps are attached to the relatively stiff clamp holder pad and are positioned topside thereof on opposite sides of the clamp. The straps have 'VELCRO' fasteners for securing the straps when the straps are wrapped around a patient's head extending directly underneath a patient's nose and across a patient's chin to firmly position the device on a patient's head at one side of a patient's mouth.

A preheatable scrim and method of use for bonding together multiple layers of materials to form a laminate. The scrim includes a carrier layer which is impregnated with an adhesive having a melting point such that it can set and hold a bond. The scrim is preheated to its activation temperature and sandwiched between the materials layers. The sandwich is pressed together to bond the layers.

Monoclonal antibodies have been developed that bind with one or more proteins located on the surface of gametes or zygotes of malaria parasites. These antibodies are specific for antigens on mosquito midgut stages of malaria parasite and sterilize the parasites in mosquitoes otherwise capable of transmitting the disease. The monoclonal antibodies are specific for the 255, 59 and 53 kilodalton surface proteins on Plasmodium falciparum and for the 25 kilodalton surface protein on zygotes and ookinetes of Plasmodium gallinaceum.
