Abstract: A modular pyrotechnic launch unit includes a launch module, a first module, and a second module. The launch module includes a launch barrel. The first module is coupled in series to the launch module. The first module includes a first ignition state in which the first module ignites a pyrotechnic element that will then pass through the launch barrel. The first module also includes a first pass-through state in which the first module allows a pyrotechnic element ignited by another module to pass through the first module. The second module is coupled in series to the first module. The second module includes a second ignition state in which the second module ignites a pyrotechnic element that will then pass through the first module and through the launch barrel.

Abstract: One aspect of the invention provides a firing apparatus that provides an arcuate visual effect. The firing apparatus includes a motor, an enclosure housing the motor and an arm connected to a shaft of the motor for moving a pyrotechnic device such as a gerb. Another aspect of the invention provides a pyrotechnic system that includes a firing apparatus including a reciprocal motor, a firing arm having a first end connected to a shaft of the reciprocal motor and a second end adapted to emit an arcuate pyrotechnic effect, a control unit in communication with the firing apparatus for controlling operation of the reciprocal motor and an ignition unit in communication with the firing apparatus for initiating the pyrotechnic effect.

Abstract: Apparatus and method for separating and replacing a cap from a shank of a tip of a welding electrode. The cap and the shank form a peripheral hollow joint that is defined by a recessed end surface of the shank and a back surface of the cap. The apparatus includes a guide frame having a recessed portion sized for receiving the tip of the welding electrode. The apparatus also includes a cap withdrawing tool movably mounted on the guide frame. The tool has two facing wall sections each having a wedge that is inserted in the peripheral hollow joint. The wedge is forced against the back surface of the cap and removes the cap from the shank by means of a driving mechanism that moves the cap withdrawing tool toward the tip of the welding electrode that is engaged in the recessed portion of the guide frame.
