Abstract: A hand tool adapter for bench operation comprising a frame including a cradle adapted to receive one handle of a two-handle hand operated tool. The adapter includes apparatus for securing the handle in place in relatively fixed relationship with the base. An actuator arm is coupled via a linkage to the base and includes a receiver for the other handle of the hand operated tool. The base positions the jaws or working portion of the hand tool to the front of the base available for clearer visibility by the operator. The linkage provides mechanical advantage for the operator to minimize and tend to standardize the force required for actuation of the hand tool. The handle of the apparatus is dimensioned and positioned to provide a clearly defined range of movement from unoperated to operated positions. An adjustable stop limits travel of the operating handle.

Abstract: A mounting structure for a pair of transducer heads has a base and integral riser beam for forming a rigid inverted T-shaped structure wherein the riser beam extends perpendicularly to a midportion of the base. The transducer heads are mounted on opposite sides of the riser beam. The supporting structure may have a pair of T-shaped profiles extending at right angles to each other. Individual tilt adjustment with or without azimuth adjustment facilities may be provided for each transducer head.

Abstract: Methods and apparatus for mounting a device and adjusting its position employ a mount for the device and provide spaced isthmi located on a predetermined axis. The portion of the mount between the spaced isthmi is rendered tiltable about the mentioned axis. The device is mounted on the tiltable portion and its position is adjustable by tilting such portion about the mentioned axis.
