Abstract: An apparatus which integrates the remote positioning and operation of hand-held tools. The apparatus has a base and an elongated tube which is connected to the base at one of its ends via a pivot. The tube has a spirally grooved interior surface. The other end of the tube is adaptively engaged to a threaded elongated cylinder of similar manufacture to the tube. The cylinder can be screwed or rotated in and out of the tube by the use of a screw turn. While one end of the cylinder is engaged to the tube, the other end is connected to a seat that holds the tool. The tool is held in place on the seat either by seat design or by use of a clamp. The seat-cylinder connection may be modular to permit the seat to be changed as required. The operation of the tool, the pivot and the screw turn are controlled by a power control panel located either on the base or the tube of the apparatus.

Abstract: A spring is continuously acting on an upper part adjustable in the height by a spindle for compensating the weight of the vertical adjustable parts. An additional compensating spring acts over a piston on the upper part. By means of a screw which can be screwed in a threaded hole, the piston can be coupled with the base which is not displaceable in the height so that the effect of the additional spring is cut off. Many compensating springs can be provided which, at choice, can be rendered effective or ineffective in order to compensate for different weights.
