A planar board having ease of retrieval and strike indicator includes a base, a first and second fishing line release extending outward from the base, a rotary flag pivotally attached to said base, and at least one line retainer. The second fishing line release preferably has a means for positively retaining a fishing line. The fishing line is inserted into the first fishing line release, behind the positive retaining means of the second fishing line release, looped around an upstanding projection disposed on the rotary flag, and preferably inserted into at least one line retainer. When a fish strike occurs, the flag will be pulled downward. To retrieve the planar board into the boat, the user jerks the fishing line such that the fishing line is pulled out of the first fishing line release. The planar board also has other preferable embodiments which add or remove a fishing line release or remove the rotary flag.

Planar board having strike indication and ease of retrieval

A planar board having ease of retrieval includes a base, a first fishing line release extending outward from substantially a front of the base, a second fishing line release extending outward from substantially a middle of the base, and a line retainer. A fishing line is retained by inserting thereof under the first fishing line release, inserting the fishing line release into a second fishing line release with preferably a peg, the fishing line is then inserted into a line retainer disposed at substantially the end of the base. A planar board with ease of retrieval allows a user to retrieve a planar board without tangling it with other planar boards being fished adjacent it. A planar board with ease of retrieval and strike indicator allows a user to easily retrieve the planar board and have notice of a fish strike.

A storage container with self-retaining lid includes a lid and a storage container. The structure for attaching the lid can be molded on to the bottom of the storage container, molded to the top of the lid, or molded to the lid and the bottom of the storage container. There are several preferred embodiments of the self-retaining lid. In a first preferred embodiment, the lid has a rim with a recessed cavity for receiving a lip of the storage container. In second and seventh preferred embodiments, a bottom of the storage container has a lip which is sized to be inserted into a sealing cavity of the lid. In a third preferred embodiment, a bottom of the storage container has a plurality of balls which are disposed to mate with a plurality of sockets. In a fourth preferred embodiment, a plurality of hooks are molded into at least two sides of the container and sized to receive the peripheral edge of the lid. In a fifth preferred embodiment, the bottom of the storage container has a plurality of corner lips which are sized to be firmly inserted into the sealing cavity of the lid. In a sixth preferred embodiment, the lid has a plurality of blocks with recessed cavities for firmly receiving a lip of the storage container. A lid of a styrofoam cup may be attached to the bottom thereof by molding a recessed cavity in the lid. A lid of a glass jar may be attached to the bottom thereof by molding a lip with thread projections in the bottom of the jar. A lid and storage container include a sealing structure that allows moisture to escape in a first position and seal in a second position.

A process for etching III-V nitride and III-V nitride alloy materials first implants selected regions of the materials with ions and then selectively etches the implanted regions in an etching liquid, such as an aqueous base. The etch depth is controlled by the energy, mass and dose of the implanted ions.

A method and apparatus for overpressure protection of a catheter from an indwelling catheter. A method in one embodiment includes injecting an agent into the catheter and relieving overpressures in the catheter during the injecting step. The agent is typically a declotting agent and the obstruction is typically a clot (e.g., blood clot). In one embodiment of the apparatus, a catheter includes a cannula and a first hub and a second hub, each of which are coupled to the cannula. The first hub is for receiving an agent which is placed into the cannula to remove an obstruction, and the second hub includes an overpressure relief valve for relieving an overpressure condition in the cannula. Other embodiments of the invention are also described.

A safety fishing line release includes a first arm, a second arm, a spring, a first frictional pad, a second frictional pad, and a peg. The first arm has a tab opening at a first end which is sized to loosely receive a tab disposed at a first end of the second arm. The first and second frictional pads are fastened to the second ends of the first and second arms, respectively. A peg extends outward perpendicularly from the second frictional pad. A spring is inserted between the first and second arms, the spring forces the first frictional pad against the second frictional pad. A second safety feature utilizes a first and second prong to retain the fishing line instead of the peg or in combination with thereof. The safety fishing line release may be further improved by adding a force adjustment device. A second preferred embodiment of the safety fishing line release utilizes a force adjustment device and a simpler design. All safety fishing line releases which have cam assemblies may be called cam operated fishing line releases.

Cam operated fishing line release

A safety fishing line release includes a first arm, a second arm, a spring, a first frictional pad, a second frictional pad, and a peg. The first arm has a tab opening at a first end which is sized to loosely receive a tab disposed at a first end of the second arm. The second arm has a pad opening at a second offset which is sized to facilitate insertion of the second end of the first arm therethrough. The first and second frictional pads are fastened to the second ends of the first and second arms, respectively. A peg extends outward perpendicularly from the second frictional pad. A peg opening is formed in the first frictional pad and second end of the first arm. A spring is inserted between the first and second arms, the spring forces the first frictional pad against the second frictional pad such that a fishing line maybe fictionally retained between the first and second frictional pads. A typical fishing line release may be also improved by adding a peg to eliminate the possibility of detachment from a fishing line. The safety fishing line release may be further improved by using the peg as a pivot to retain a pulley. A second safety feature utilizes a first and second prong to retain the fishing line instead of the peg or in combination with thereof. The safety fishing line release may be further improved by adding a force adjustment device. A second preferred embodiment of the safety fishing line release utilizes a force adjustment device and a simpler design.
