Present invention relates to a rotary positioner that allows a welding table's work surface to be set at an angle as desired by a user. Two vertical frames can move and slide along the length of a chassis-bar to adjust the distance between the two vertical frames. As long as the length of a welding table does not exceed the total greatest distance between the two vertical frames, the present invention can fit any work table or welding table. Caster wheels and height adjustment knobs allow for easy movement and balancing of the rotary positioner.

A lockout unit coupled to a gate to provide selective access to an electrical machine is provided. The lockout unit includes a stationary bracket, an arm, and a removable bracket. The stationary bracket includes a first aperture defined therein, and the arm includes a second aperture defined therein. The arm is selectively movable between an open position in which the arm is spaced from the stationary bracket, and a closed position in which the second aperture is substantially concentrically-aligned with the first aperture to receive a locking device therethrough. The removable bracket is selectively coupleable to the arm when the arm is in the closed position. The removable bracket includes a third aperture defined therein that is selectively aligned with one of the first aperture and the second aperture to receive the locking device therethrough when the removable bracket is coupled to the arm.

A method of providing motion using a loop-band device is disclosed. An outer, restraining loop constrains an inner, buckling loop to form a buckled mode having one or more buckles. An activation force generated in one of buckles provides a stress, resulting in a change of configuration of the buckling loop that produces movement of the restraining loop. Depending on the composition of the buckling loop, the stress is generated via heat, light, an electric current or voltage, a magnetic field, or a combination thereof. The restraining loop is a suitably thin, relatively inextensible but flexible material. The buckling loop is a suitably thin, relatively flexible, reactive material that develops stress when subject to suitable activation forces. Suitable reactive materials include electroactive polymers, electrostrictive materials, magnetostrictive materials and materials having a high coefficient of linear, thermal expansion. The motion is linear or rotary, depending on device configuration.

An earth working machine (10) encompasses a machine body (13) having a machine frame (12) and a drive configuration (46), rotationally drivable relative to the machine frame (12) around a drive axis (A), to which configuration a working apparatus (32) embodied for earth working is releasably connected in torque-transferring fashion, in an operating position operational for earth working, for rotation together around the drive axis (A), such that when the connection is released, the working apparatus (32) is removable from the operating position in an axial direction relative to the drive configuration (46) for deinstallation from the drive configuration (46) and, for installation on the drive configuration, is conveyable into the operating position in an axial direction relative to the drive configuration (46).

According to the present invention, there is provided on the drive configuration (46) an actuator (65) that encompasses an actuator member (63), movable relative to the drive configuration (46), which, when the working apparatus (32) is located, in preparation for installation thereof on the drive configuration (46), in a preparation position located axially remotely from the operating position, is conveyable directly, or indirectly with interposition of a coupling structure (94a), into installation force-transferring engagement with a counterpart coupling structure (74g) of the working apparatus (32), the working apparatus (32) being capable of being brought by the actuator (65), upon establishment of an installation force-transferring engagement, from the preparation position closer to the operating position.
