Abstract: A tool is described for mounting and demounting splined joints, especially those found in the front-wheel drive assemblies of cars. A special tool is provided which can be inserted into the internally splined wheel hub rotatably fixed to the vehicle and which screws on to one end of the externally splined drive shaft portion being installed in the hub. The other end of the tool mounts to a slide hammer. When the slide hammer weight is banged against the tool or against the oppositely located hammer stop, the momentum impulse is transmitted to the splined shaft to push it out of or into the splined wheel hub, depending upon the direction of movement of the hammer weight. The tool is successful even with interference fit splined joints otherwise requiring large press forces for assembly or disassembly.

Abstract: An ophthalmic lens centering and mounting device includes a base which receives and centers the ophthalmic lens. A support receives a holding and securing device for the lens in a removable way and is carried by an arm mounted to swing on the base to apply the holding and securing device to the ophthalmic lens. A barrel mounted to rotate on the arm carries the support. A template support carried by the barrel receives in a removable way a template that has to be superposed on the lens before the holding and securing device is placed on the lens.

Abstract: A positional fixation element is located on a first structural component and positionally fixes a second structural component, which is to be joined to the first component at a predetermined orientation relative thereto. The positional fixation element is substantially in the form of a stud, which protrudes beyond a reference plane of the first component. The positional fixation element is produced by means of a mandrel-like tool, which is pressed into the first component on an incline relative to the reference plane. In the process, material is displaced, so that on the one hand a groove-like indentation is formed, and on the other hand, an accumulation of material having a shape corresponding to that of the positional fixation element is created above the reference plane. The positional fixation element is suitable for positionally fixing electrical circuits, for example, or other components when glued or soldered onto the first component.

Abstract: A two station, single action vise has a body, with a fixed center block forming oppositely facing fixed jaws, and movable jaws at opposite ends of the body that are moved by operation of a vise screw toward one of the respective oppositely facing fixed jaws in the center of the body. The vise screw is spring centered and will yield to apply a preclamp with one of the jaws onto a piece part. The movable jaws are shown operated by a vise screw that has left-hand threads for operating one of the movable jaws and right-hand threads for operating the other movable jaw, so that as the screw is rotated both movable jaws move simultaneously toward the center block forming the fixed jaws. In this way two work pieces can be clamped by the movable jaws against the center fixed jaw. In order to preclamp piece parts under a spring load the screw is moved so it can shift axially slightly under spring load after preclamping one part until both movable jaws are positioned to clamp their respective piece parts tightly.

Abstract: A vise has a housing block formed with a guide defining a longitudinal direction, a fixed jaw secured to the block, a movable jaw displaceable in the direction in the guide relative to the fixed jaw, and a spindle extending in the direction between the jaws along a spindle axis. A support at the fixed jaw has a formation fitting with the fixed jaw and fixing the support and fixed jaw together against relative axial displacement while permitting limited relative pivoting about a fixed-jaw axis generally perpendicular to the spindle axis.
