US Patent:

6647910, Nov 18, 2003

Filed:

Sep 13, 2001

Appl. No.:

09/951603

Inventors:

Ian Arthur Royle - Houston TX 77031

International Classification:

B63B 134

US Classification:

114 67R, 405 21

Abstract:

This invention relates to methods for absorbing impacting shock loads from waves on marine hulls by using a diffuser to provide a reduced impact zone forward of the hull and to divide the wave and cause the non-compressible liquid of the wave to mix with air in the diffuser channels to form a compressible fluid to further absorb impacting shock loads. This system was invented to provide for wave shock absorption of wide bow flat-bottomed marine hulls. These hulls being more buoyant and stable, provided more usable space, while possessing very efficient planing hulls that are easier to manufacture than three dimensional pointed bow hulls.

Appl. No.:

8/367738

Inventors:

Ian A. Royle - Stafford TX

International Classification:

F16B 2300
F16B 3500

US Classification:

411389

Abstract:

A threaded tubular fastener having an elongated central through-bore having engaging means for engaging said through-bore with a rotary device having a rotary driver, a generally cylindrical body having an external surface with a main external thread formed thereon with a plurality of slots, said thread being larger than the diameter of a pre-drilled hole in a first work piece and a second mating work piece wherein the said threaded tubular fastener is employed to fasten the first work piece to the second work piece.

Appl. No.:

Inventors:

Ian A. Royle - Houston TX

International Classification:

F16B 3712
F16B 39284
F16B 2500

US Classification:

411178

Abstract:

A threaded self-locking fastener, having a hollow body open at both ends and an elongated central through bore with a slot extending the length of the hollow body. Version 1 has sharp edges on the slot that dig into the bore of the work piece to prevent rotation. The fastener is used in conjunction with an internal driver. The driver located in the bore of the fastener engages detents to produce rotary drive motion. The driver also has a means of manipulating the first and second edges to facilitate assembly and disassembly. Version 2 has curved or chamfered edges in the slot and inward facing lobes also used in association with a driver. Rotation of the driver against the lobes causes the tubular fastener to be reduced in diameter against spring tension thereby allowing the fastener to freely rotate in the threaded bore of the work piece. By releasing the driver, the fastener expands and self locks in the threaded bore. Version 3 has a sharp edge on one side of the slot and a curved lobe on the other and is spring tensioned to cause the sharp edge to dig-in and prevent counter-clockwise rotation.
