Abstract: A lighting fixture arrangement, an adjustable lighting fixture connector, and a method of installing a lighting fixture arrangement.

Abstract: A forestry machine configured to cut timber, where the forestry machine comprises a felling head including a support frame having an accumulation pocket, an accumulating arm, and a harvest arm. The forestry machine further comprises a stator having coils thereon adapted to produce a time varying stator magnetic field, a rotor having at least either a set of slots or a set of permanent magnets mounted thereon facing the stator and adapted to produce a radially directed flux or an axially directed flux. The rotor is rotatably coupled to the stator in axial alignment therewith by the time varying stator magnetic field. The rotor comprises a saw blade.

Abstract: A multi-mode power train and multi-mode vehicle include a power-conversion device that is in communication with an engine via a direct mechanical power-transfer connection extending from the engine to the power-conversion device. A continuously variable power source (CVP) is in communication with the power conversion device via an intermediate power-transfer connection. A lock-up device with first and second engagement states is provided between the engine and the power-conversion device or the CVP. With the lock-up device in the first engagement state, mechanical power from the engine is converted by the power-conversion device for use by the CVP, with the CVP using the converted power to provide mechanical power to a power-output connection. With the lock-up device in the second engagement state, the engine transmits mechanical power through the lock-up device to the power-output connection.

Abstract: The present invention incorporates a free swing system into the hydraulic flow system of a boom crane in order to permit an operator to control the boom crane during the centering operation, which occurs immediately before and during the hoisting of a load. The free-swing system is incorporated into the hydraulic flow system between the swing control valve and the hydraulic swing motor and operates by "bleeding-off" a portion of the hydraulic fluid being pumped to or by the hydraulic swing motor so as to greatly reduce or control the rotational speed of the hydraulic swing motor.

Abstract: A structural bearing comprising a bottom bearing plate and a top bearing plate, the bearing having sliding surfaces in mutual sliding contact and fixed against horizontal movement relative to the bottom bearing plate and the top bearing plate respectively, one of the bearing plates being provided with one or more spigots engaging in slots in the other bearing plate, the spigot(s) substantially preventing relative rotation of the bearing plates about a vertical axis and substantially preventing relative horizontal movement of the plates in one direction but allowing relative horizontal movement of the plate in a direction normal (i.e. at a right angle) thereto.

Abstract: A modular element for a bridge or structural bearing having metal plates encased within layers of vulcanized rubber is formed in a press including a lower member with at least one post or pin extending upwardly through corresponding holes in the metal plates. A vulcanized rubber plug is inserted and retained in each hole in the modular element after it is removed from the press.
