Abstract: Automatic hand guns in contrast to conventional pistols are commonly supplied with reversing hammer mechanisms for the firing pins immediately above and adjacent to the top of the grip which is set in motion by pulling the trigger. A magazine for shells is held in place in the handle by use of a releasable catch which must be readily manipulated by hand when a magazine is to be removed and replaced. Cushion-type reinforced replaceable grips have portions of the reinforcement specially formed at critical locations to make certain that there is no deformation of those portions of the grip which might otherwise impair either the hammer mechanism or the magazine release.

Abstract: An arrangement for controlling the closing sequence of two wings of windows, doors, and the like, especially smoke or fire protection doors, which are closable by means of a door-closing device each. The two wings are a moving wing to be opened first and a resting wing to be opened subsequently, so that projecting edges of the doors which face each other come into contact with each other in the correct sequence. A control device is actuated primarily by the slide rollers of the door-closing device of the resting wing when the resting wing is opened. With the use of a control lever and a sliding member displaced by the control lever toward the axis of rotation of the resting lever, a locking member is pivoted into the return end region of the guide roller of the door-closing device of the moving wing. This locking member locks the final closing movement of the moving wing until the resting wing has been closed.

Abstract: When sanding for instance panelled doors in a belt sanding machine it must be prevented that transversely extending parts (16) are sanded since it would be harmful to sand across the direction of the grain of the wood. A machine according to the invention is therefore provided with a combined sensing and control device which in a simple and effective manner will prevent damage caused by the sanding process by controlling the contact of the sanding belt with the workpiece. The device consists of a disc (14, 20) which is mounted on the sanding equipment. The disc (14, 20) protrudes a distance beyond the sanding position of the sanding belt (15), in order that the disc will sense the workpiece when the workpiece is moved under the sanding belt. When the disc (14, 20) rolls across a frame piece (16) the sanding belt (15) is pivoted up above the wood, and when the disc (14, 20) meets a recessed part (18), the sanding belt (15) is pivoted to a non-sanding position.
