Abstract: In one aspect, the present invention relates to an erosion-and-sediment-control system. The erosion-and-sediment-control system includes a sleeve having a substantially-flat bottom surface and a fiber matrix disposed within, and substantially filling, the sleeve. A flap is formed at a first end of the sleeve. The substantially-flat bottom surface resists movement due to wave action and currents.

Abstract: A latch mechanism (1200) comprises a resilient wire (404) supported proximate its first end (412) and second end (414) by a support structure (406). The latch mechanism (1200) also includes one or more hook shaped catches (218) that have cammed outer surfaces (302) and wire engaging openings (304). To engage the latch mechanism (1200) the resilient wire (404) is urged against the cammed outer surfaces (302) bending the resilient wire (404) and allowing the resilient wire to rebound into the wire engaging openings (304). To disengage the latch mechanism the resilient wire (404) is deflected, e.g., by pushing a moveable manual actuator (408) that is engaged with the wire, in order to release the resilient wire (404) from the wire engaging openings (304) of the catches (218).

Abstract: An adjustable stroke reciprocating mechanism which includes a reciprocating member mounted for reciprocating movement, a rotating member mounted for rotation about a main axis (XX), a connecting rod operatively connected to the reciprocating member and a crank assembly including a crank arm having a longitudinal axis (Y) which is inclined with respect to the main axis (XX). At least a portion of the crank arm can revolve about the main axis, the connecting rod being operatively connected to the crank arm and its position adjustable along the length thereof in either direction along a longitudinal axis (Y). There is also provided various bearing mounting assemblies for use with the adjustable stroke reciprocating mechanism and carrier and shaft assemblies allowing controlled movement along the longitudinal axis (Y) of the crank arm.

Abstract: A rotary/linear converter comprising a reciprocator having a main axis (A) and being adapted for reciprocating movement in the direction of the main axis (A) and a rotator adapted for rotating movement about the main axis (A), the converter further including converter means which operatively interconnects the reciprocator and the rotator. The converter means includes a control link having one end portion thereof pivotally connected to another part of the converter means and the other end portion pivotally connected to a mounting, the link being adapted to pivotally oscillate about the mounting in response to movement of one of said either the rotator or the reciprocator thereby causing movement of the other.
