Abstract: A power tool supportable by a lanyard. The power tool includes a motor housing, a motor arranged in the motor housing, a front housing, an output member extending from the front housing, a gear case, and a gear train arranged in the gear case. The gear train configured to transfer torque from the motor to the output member. The power tool further includes a first fastener securing the front housing to the motor housing and a bracket to which the lanyard is attachable. The bracket is fastened to one of the front housing, the motor housing, or the gear case by a second fastener that does not secure the front housing to the motor housing.

Abstract: A rotary impact tool includes a housing, an electric motor, and a drive assembly for converting a continuous torque input from the motor to consecutive rotational impacts upon a workpiece of at least 900 ft-lbs of fastening torque. An anvil has a bore defining a hexagonal cross-sectional shape and having a nominal width of 7/16 inches. A hammer is rotationally and axially movable relative to the anvil for imparting the consecutive rotational impacts upon the anvil. A spring biases the hammer in an axial direction toward the anvil. A battery pack has a nominal voltage of at least 18 Volts and a nominal capacity of at least 5 Ah. The rotary impact tool has an overall weight including the battery pack that is less than or equal to 7.5 pounds. A ratio of the fastening torque to the overall weight is greater than or equal to 120 ft-lbs per pound.

Abstract: A power tool may include a compartment in its housing and a first printed circuit board (PCB) located in the housing and electrically coupled to a first connector. An insertable wireless communication device may include a second electronic processor and an antenna that are each mounted to a second PCB. The insertable wireless communication device may be configured to be received in the compartment and may include a second connector configured to electrically and physically couple to the first connector. The insertable wireless communication device may be configured to wirelessly communicate with an external device. When the insertable wireless communication device is inserted into the compartment, a first conductive layer of the first PCB may be configured to be electrically coupled to the antenna via the first connector and the second connector such that the first conductive layer of the first PCB serves as a ground plane of the antenna.

Abstract: Nitrocellulose propellant compositions are provided comprising as ballistic modifier a copper II complex of a C.sub.6 -C.sub.12 chain aliphatic carboxylic acid, advantageously in conjunction with one or more conventional ballistic modifiers for example, lead or copper compounds such as lead stearate, lead acetophthalate, lead .beta.-resorcylate and basic copper salicylate. The preferred complex is copper II caproate. The propellant compositions exhibit good quality plateau or mesa burning over a useful pressure range for a wide range of energy and burning rates. The copper II complexes are especially advantageous in cast double base propellants particularly because their solubility in the organic solvents used facilitates their incorporation into these compositions.
