Abstract: This invention is directed to a firearm safety device that has a chamber block for being received in a chamber of a firearm. An internal area is defined in the chamber block and can receive a bullet so that the bullet biases the outer walls outward. A visual indicator is attached to a distal end of the chamber block and is received in the bore of the barrel and extending outward past the muzzle providing a visual indication that the firearm is in a safe condition. In one embodiment, the chamber block can be inserted into the muzzle and the visual indicator extends through the barrel and chamber and out of the ejection port of magazine well. The visual indicator can be modifiable in length to accommodate various lengths of barrels and can be flexible.

Abstract: A dry dock upon which a small watercraft may be docked in a dry condition and from which a boater may access from an associated structure for launching the watercraft without entering the water is disclosed. The dry dock comprises a floating dock having a forward end and a rear entry end. A motion mechanism connects the floating dock to the pier. The motion mechanism includes a mechanical pivot carried by the floating dock by which the floating dock is connected to the associated structure. The floating dock pivots about the pivot during docking and launching of the watercraft in a seesaw motion. A buoyant fulcrum is included in the floating dock which provides buoyancy and assists the seesaw motion of the floating dock during docking of the watercraft.

Abstract: This invention defines a system and method for manufacturing three-dimensional articles from a design created on a CAD item. The article is made using particle deposition of a fluent material to a build-up on a servo assembly base. The fluent material is deposited in the form of droplets from a dispensing head of a head assembly by moving the assembly up and down in a reciprocating motion according to the three-dimensional design coordinator. A droplet of fluent material forms as the dispensing head moves downward and makes contact with the article being formed, as the head reaches its lowest position of travel. The surface tension and capillarity of the fluent material is used to form the mass and shape of the droplet at the top surface of the article as the dispensing is moved upwards. The size and shape of each droplet may also be controlled by the type of fluent material used as well as its temperature and pressure and the size of the dispensing head orifice.

Abstract: An apparatus and method for producing three-dimensional articles from a computer aided design includes one or more mold modules, each containing a pin array containing a plurality of pin elements. The pin elements are moveable in response to a data file containing three-dimensional coordinates of the three-dimensional article to be molded wherein the coordinates have a resolution corresponding to the resolution of the pin elements in the pin array. By moving the pins to the various coordinates of the data set, a mold shape is provided for molding the three-dimensional design.

Abstract: A spray skirt (A) is disclosed for covering the cockpit opening (14) of a kayak (10). The spray skirt includes a fabric cover (24) for spanning the opening which includes an elastic band (B) secured around the perimeter of the cover for retaining the spray skirt about a rim (16) of the opening. The retaining band includes outer and inner elastic bands (30, 32) joined by a compressible bulbous retention element (34, 40). The inner band 32 is of sufficient width to prevent contact of the interior fabric (24b) of the cover from being abraded by lip contact. The preformed outer band (30) includes a first outer band (30a) extending from the bulbous element upwardly and outwardly terminating at a bend (35), and a second outer band (30b) extending from the bend upwardly and inwardly.

Abstract: A system and method for producing a three-dimensional object (10, 70) from coordinates generated on a computer machine (12) is disclosed wherein the object has improved dimensional accuracy. Control signals (20b) are generated for controlling a servo (20) that controls a reaction or interaction of material (20a) at the coordinate points to form the object while a second servo (22) serves to build up a three-dimensional support system (42) in response to support control signals (22b). Support control signals (22b) are generated at the same time the coordinate points of the design are generated to specify strategic points of the object at which a support environment need be placed in order to insure the dimensional accuracy of the object avoiding warpage or other dimensional distortion. As a support environment, a series of webs (50, 52, 54) or columns (76), or encapsulation (44, 92) may be provided for providing a support environment for the object.

Abstract: A catamaran kayak is disclosed which comprises a plurality of hulls (10, 12) which are joined together and laterally spaced by elongated connectors (B). Flexible couplings (C) are formed on the hulls which receive the ends of elongated connectors (B) and provide for flexibility between the hulls and the elongated connectors in three degrees of freedom. The flexible couplings include flexible bosses (30) which are formed on the kayak hulls and which receive the ends of the elongated connectors. Journals (36) are carried in the flexible bosses and flexible bushings (38) may be carried between the elongated connectors and the journal to control the amount of flexibility provided. This enables flexibility of each flexible coupling (C) to be controlled, if desired, in accordance with the style, weight, and other characteristics of the individual boaters, as well as tailoring the catamaran kayak for the type of water conditions in which it is used.

Abstract: A watercraft such as a canoe and the like which is propelled by paddling is disclosed that can be paddled on one side and propelled generally in a straight line. The watercraft includes an asymmetrical hull which is asymmetrical along its length and also from side to side. There is a larger volume on one side of the longitudinal center line of the hull than the other. A keel line defined by the bottommost portion of the hull forms a sinuous path from the bow to the stern. For a right handed paddler, the large volume is on the starboard side in the bow section of the hull, and is on the port side in the stern section of the hull. The keel line changes over at a transition section which is symmetrical from the port to the starboard side.

Abstract: A flexible security loop (A) for a flexible kayak hull (12) is disclosed which includes a flexible vinyl covered strand (16) having enlarged ends (34, 36) which fit through an enlarged center opening (32) of a bracket slot (30) to interlock at slot ends (26, 28), and attach the strand to the hull in the form of flexible loop (A).

Abstract: A system and method for constructing a three-dimensional object (10) from a design created on a CAD machine (14) is disclosed which includes a support (B) which may be indexed along two coordinate axes (X, Y) and a movable dispensing head (A) which indexes along a Z-axis. A fluent material (54) is dispensed or extruded from head (A) and as it is dispensed, the fluent material is subjected to a treatment by treatment sources (D) which cause the fluent material to transform into a fixed solidified state in the form of a three-dimensional object. Fluent material (54) may be a polymeric material which is solidified by an energy beam of ultraviolet light (56) upon dispensing. A shield (E) is provided to shield the dispensing head (A) and strand of material (54) so that the material is treated at the proper time and location to cause it to solidify properly to form the three-dimensional object. In accordance with the method, indexing takes place in desired steps so a dimensionally accurate object is formed.
