A soft tip game dart (,) comprising a plastic tip portion (,), a metallic body portion (,), and a flight or tail portion (,). The tip portion is received in a bore (,) in the portion and is biased forwardly in the bore by a spring and plunger (,). Cross-sectionally, non-annular peripheries of the bore and head section (,) of the tip cooperate to limit relative rotational movement therebetween.

Soft tip game dart

A game dart (10) is provided with a flight section (24) extending axially rearwardly from the rearward end (32) of a body section (20) and having at least a portion thereof (38/40) axially movable relative to the body section to minimize or eliminate bounce-outs or deflections or subsequently thrown darts striking a previously thrown dart embedded in a target.

Game dart with retractable flight section

An improved anti-bounce-back game dart (10) is provided wherein the structure mounting the point section (22A-22G) to the body section (20A-20G) for relative axial and/or axial and rotational movement is located internally of the dart body at the rearward end (32) of the body section, preferably in an enlarged cavity (36A-36G) opening directly to rearward end of the body section and easily accessible by threaded removal of the flight section (24A-24G).

Anti-bounce-back dart

An adjustable crimping tool (10) is provided having a pair of indexable discs (18, 32) each of which carry a plurality of concave die cavities (18A-18F, 32A-32F) spaced about and opening to outer periphery thereof which can be moved into registry (FIG. 1) to define a selected size/shape of crimping cavity (C).

Adjustable crimping tool

A game dart (10) of the anti-bounce-back type is provided for use with a dartboard (10A) having rib wires (13, 14). The game dart includes a body section (20), a point section (22) axially movable in the body section and a tail section (24) fixed to the body section and carrying flight members (26). The connection (48, 50) between the point and body sections is configured to cause simultaneous relative rotational and axial movement therebetween.

A fuel injection nozzle for gas turbines in which atomization of the liquid fuel is accomplished by high-velocity air entering the combustion chamber, characterized by minimizing the surface area of metal in contact with the fuel during the atomization process and further characterized by designing the air passages such that a swirling motion is imparted to the air followed by an acceleration of the air stream to eliminate variations in air velocity and to maximize air velocity at the point of impact with the fuel.
