Abstract: A high pressure transducer, especially for ballistic pressure measurements, with a body member and a sensor part, the body member can be screwed into a threaded mounting bore provided in a structural component, whereby the body member comes into sealing contact with its sealing surface against a seating surface of the mounting aperture. The body member is provided with a recess, into which projects an extension on the sensor part to be secured along its end-face on the body member. An annular gap is provided between the extension of the sensor part and the recess in the body member, which causes the force flux lines produced by the sealing forces not to pass through the sensor part so that the latter remains unaffected by changing conditions of the force flux lines, i.e. by the prevailing tightening torques.

Abstract: A keyhole type saw is provided which includes transverse stroke control apparatus for controlling the movement of the saw blade in a direction transverse to the linear stroke path. According to preferred embodiments, the transverse stroke control apparatus includes a rotatable blade guide roll engageable directly with the saw blade, which guide roll is in turn carried at a guide lever arm. A rotary plate is supported in the housing of the saw and includes a pivot connection for a swing arm which has the other end engageable at the guide lever arm by way of cam surfaces, whereby the position of the swing arm directly controls the presenting transverse stroke of the blade guide roll and saw blades.

Abstract: An angular guide for hand routing millers formed of two legs forming an angle of 90.degree. with one another, one of the legs being fashioned as a stop plate with a smooth guiding surface and the other of the legs being constructed as a mounting plate with holding members arranged on its outside for accommodating the routing miller. Both of the legs are provided in the zone of the apex of the angle with apertures to pass the milling tool therethrough. The mounting plate is extended beyong the apex and is likewise formed as a guiding surface at least on the side facing the smooth guiding surface of the stop plate. Various mounting apertures and other members are provided on the stop and mounting plates to accommodate utilization of the angle guide in a plurality of different positions, including use of the mounting plate alone.

Abstract: In a banderolling apparatus in which banding material is wrapped around a stack of objects and tied by welding, the speed of operation and the effectiveness of the weld are promoted by applying cooling air at the welding zone through a clamping jaw adjacent the weld.

Abstract: A banding apparatus for enwrapping an object, or a group of objects, employs a system for tightening the banding material around the object of package which includes a piston-cylinder unit operated by compressed air and an adjustable valve which enables the tightening to be set at variable values to accommodate for different shapes, sizes and deformation characteristics of the object or package.
