Publication number: 20250115333Abstract: The invention relates to a catamaran hull to improve performance characteristics. The catamaran hull comprises a staggered keel and varying deadrise angles to reduce hunting phenomena and improve sea-keeping, handling, and turning abilities of the catamaran. The hull includes a forward keel centered on each sponson, a mid keel moved inward relative to the forward keel, and an aft keel moved inward relative to the mid keel. This catamaran hull provides a solution that reduces undesirable phenomena such as hunting and outward leaning during turns, while improving stability and maneuverability. Overall, it offers enhanced performance in various water conditions through its unique staggered keel configuration and optimized hull geometry.Type: ApplicationFiled: October 4, 2024Publication date: April 10, 2025Inventor: Stephen Dougherty

Publication number: 20250115334Abstract: The invention relates to a catamaran hull system to improve performance characteristics. The catamaran hull system comprises a hull having a bow and a stern, at least one transverse step, and a posi-flow inductor system. The posi-flow inductor system includes an interior inductor channel extending vertically up the hull and terminating above a waterline when the hull is at rest, and a posi-flow cover plate attached to the hull and covering the interior inductor channel to form a posi-flow duct. This catamaran hull system provides a solution that reduces suction, improves air flow to the transverse step, and enhances overall hull efficiency. Overall, it offers improved performance, stability, and handling characteristics for catamaran vessels.Type: ApplicationFiled: October 4, 2024Publication date: April 10, 2025Inventor: Stephen Dougherty

Publication number: 20250115332Abstract: The invention relates to a system and apparatus to improve performance characteristics of catamaran hulls. A catamaran hull comprises two sponsons, each sponson having an inner chine, and at least one chine extension attached to the inner chine of at least one sponson. The chine extension extends into a tunnel between the two sponsons and is angled downward from a horizontal plane. This system and apparatus provide a solution that generates lift by increasing the surface area of the chine and allows the catamaran to lean into turns rather than outward. Overall, it offers improved stability, reduced drag, and enhanced maneuverability for catamaran boats, particularly at higher speeds and during turning maneuvers.Type: ApplicationFiled: October 4, 2024Publication date: April 10, 2025Inventor: Stephen Dougherty

Publication number: 20070114819Abstract: A folding seat assembly to provide easy access to a storage area behind the seat for use particularly in boats or aircraft. The seat assembly allows a seat (32) to be folded into a seat box (1) and rides on a pivot pin (27) within a track aperture (26). A lock (11) is provided to secure the seat within the seat box. An upper handle (9) on the bottom of the seat frame assist the user in lowering the seat to an open use position. A lower handle (10) allows the seat box to be lifted upward for access to storage and equipment behind the seat. The seat box is supported in the latter position by at least one lifter (21) attached to a back of the seat box and a support on the boat or aircraft in which the seat assembly is used.Type: ApplicationFiled: November 18, 2005Publication date: May 24, 2007Inventor: Stephen Dougherty

Patent number: 4107260Abstract: Methods are provided for processing expandable thermoplastic materials with a typical compression relief design extruder screw having a helical flight for advancing and working a thermoplastic material. The screw is modified to shorten the feed and compression sections and to include a plurality of force-producing components in at least the compression section of the screw such that at least some portion of the components in any one turn of the flight lie in one plane essentially normal to the axis of rotation of the screw and such that the walls of the flight are uninterrupted. This arrangement controls the location of the rupturing or fragmenting of what is referred to as the solid bed and controls the manner in which it is fragmented to provide an extrudate at a die end of the extruder which has a constant temperature and which is uniform throughout each successive section of the thermoplastic material.Type: GrantFiled: December 14, 1976Date of Patent: August 15, 1978Assignee: Western Electric Company, Inc.Inventor: Timothy Stephen Dougherty

Patent number: 3947173Abstract: First and second concentric insulating sheaths of plastic materials are formed continuously around a filamentary core advancing longitudinally through an extrusion chamber. The core is passed axially through a tapered entrance portion and a coaxially aligned tapered throat portion formed in a separable die disposed in the chamber. Fluent plastic material for the first sheath is delivered from a main extrusion bore, impinging on the core circumferentially at the entrance portion of the die, the flow thereof being developed as it passes into the throat portion thereof. Fluent plastic material for the second sheath is delivered from an auxiliary extrusion bore flowing through a plurality of dividing channels formed in the die and radially inward at a plurality of circumferentially spaced points around the die axis into an annular manifold or reservoir where the fluid pressure of the plastic achieves a steady state condition.Type: GrantFiled: May 28, 1974Date of Patent: March 30, 1976Assignee: Western Electric Company, Inc.Inventor: Timothy Stephen Dougherty
