Abstract: Various embodiments of the present disclosure provide a curtain wall panel bracket leveling system that facilitates leveling a panel bracket mounted to a fixture (such as an embedment or an anchor array) cast in a concrete slab.

Abstract: Various embodiments of the present disclosure provide a curtain wall panel installation system. The curtain wall panel installation system of the present disclosure includes a plurality of rails each forming an elongated panel bracket spanning an entire edge or substantially the entire edge of a concrete floor slab of a given floor of a building. Each elongated panel bracket is mountable to anchors (such as embedments) cast in the concrete floor slab of a given floor of the building at discrete positions along the concrete floor. The elongated panel brackets enable the curtain wall panels to be laterally transported along the building façade to their respective installation positions, which enables workers to use a centralized crane location to hoist the curtain wall panels in preparation for installation.

Abstract: Various embodiments of the present disclosure provide an embedment attachment system configured to attach to a concrete form such that an embedment of the embedment attachment system has a desired edge spacing from the concrete form. Use of the embedment attachment system of the present disclosure enables precise embedment positioning with respect to the concrete form.

Abstract: A combustion nailer includes a tool housing, and a combustion engine substantially located within the housing and including a valve sleeve reciprocating relative to a cylinder head for cyclically opening and closing a combustion chamber. A control system is associated with the housing and is connected to the combustion engine for providing for a designated open time for the combustion chamber after a combustion event and before a subsequent combustion can occur.

Abstract: Various embodiments of the present disclosure provide an embedment positioning system that facilitates the positioning of a plurality of embedments along an edge of a concrete form. In one embodiment, the present disclosure provides an embedment positioning tape formed with embedment position indicators indicating the positions at which a plurality of embedments are to be positioned along a concrete form. In operation, a user unrolls and attaches the embedment positioning tape along the concrete form such that the control line location indicator lines up with the actual control line. The user then uses the embedment positioning indicators to position the embedments at the correct positions along the edge of the concrete form without having to hand-measure those positions for each embedment. The present disclosure also provides an embedment positioning tape forming system and method.

Abstract: A combustion-powered fastener-driving tool includes a tool housing, a power source associated with the housing and including a cylinder head, a cylinder and a piston reciprocating in the cylinder, a valve sleeve reciprocating relative to the cylinder, a chamber switch and a trigger switch; the cylinder head, the valve sleeve, the cylinder and the piston combining to define a combustion chamber, the closing of both switches required for initiating an ignition of the power source for driving piston down cylinder. A fan is disposed in the combustion chamber, and a control system includes a control program associated with the housing, connected to the power source, the chamber switch and the trigger switch, and configured for providing a designated ignition delay period after fuel is injected into the combustion chamber and when the chamber switch is closed, the delay period being variable as a function of monitored tool parameters.

A control system is associated with the housing and is connected to the combustion engine for providing for a designated open time for the combustion chamber after a combustion event and before a subsequent combustion can occur.

Abstract: A combustion nailer (10) having a combustion power source (14) defining a fan motor chamber (50) having at least one chamber wall (52, 54) and a motor shaft hole (56). A fan motor (44) is disposed in the fan motor chamber (50) and has a motor shaft (42) projecting through the motor shaft hole (56). A one way valve (60) is associated with the chamber (18) and the motor and is configured for allowing unidirectional airflow through the hole (56) past the motor (44), and preventing airflow in the opposite direction.
