In order to provide a retractor of this kind which, having a compact design, is easy to handle, it is proposed in accordance with the invention that the retaining devices each have a holding arm connected to the respective spreader arm, and both holding arms couple with the drive device and be displaceable via the drive device relative to each other and relative to the holding device along a displacement direction.

Abstract: The invention relates to a surgical retractor, particularly for the retraction of a separated sternum, with a holding device and two spreader arms, wherein the spreader arms are mounted with one end on the holding device, at a distance from each other that is adjustable in a spreading plane, and at least two retaining elements for retention of bone material, for example of the separated sternum, are arranged on each of the spreader arms. To develop this retractor for sternotomy in such a way as to permit gentler opening of the separated sternum, it is proposed that at least one of the retaining elements is mounted such that its position can be modified in the retraction direction with respect to that end of the spreader arm mounted on the holding device.

Abstract: The present application discloses a telescopic retractor holder comprising a telescopic rod with an inner tube, an outer tube and a locking mechanism as well as a retractor rod. Said retractor rod has at its one end a retractor mounting, which is adapted for releasably gripping a retractor, and at its other end is fastened to the telescopic rod by means of a jointed connection. The telescopic rod can be supported on an operating table and has an actuating mechanism, by which the locking mechanism can be transferred from a first position, in which the inner tube and the outer tube of the telescopic rod are held immovably in relation to one another, into a second position, in which the inner tube and the outer tube of the telescopic rod are movable in relation to one another in the longitudinal direction of the tubes.

Abstract: A piston for an internal combustion engine may include a piston head and a piston shaft. The piston shaft may have two shaft walls, one arranged on a pressure side and the other arranged on a counter-pressure side. Two box walls may have pin bosses and connect the shaft walls. Each of the box walls may have a first partial wall section and a second partial wall section. The first partial wall section may extend between the pin boss and the shaft wall arranged on the pressure side. The second partial wall section may extend between the pin boss and the shaft wall arranged on the counter-pressure side. A first longitudinal centre line of the first partial wall section is may be convergent to a second longitudinal centre line of the second partial wall section, wherein the first and second longitudinal centre lines—intersect each other outside the piston.

Abstract: A housing for chip card reader constructed such that is can be assembled without the assistance of tools. The housing is composed of a base, a cover that can be slipped onto said base, and a cap that joins said base to said cover. These parts of the housing are merely plugged together and are secured to one another in the assembled condition of the parts without external fasteners.

Abstract: A telephone apparatus composed of a telephone set and a device for changing its angle of inclination relative to its support surface is provided. To this end, a wire shackle is pivotably seated in the floor trough of the telephone set, whereby two different positions of the telephone set relative to its supporting surface are selectable on the basis of the shaping of the wire shackle. Portions of the shackle engagable with the support surface are provided with an elastic, riffled cladding to prevent slipping of the shackle on the support surface.

Abstract: An actuating member for a cradle switch comprises free ends with oblong holes for receiving male members mounted within the housing of a telephone set to define a pivot axis.

Abstract: A contact device for plugs is arranged on the component side of the printed circuitboard and includes soldered connections which penetrate through the printed circuitboard and are soldered to conductor paths of the printed circuitboard on the opposite side thereof. The countercontacts of a plug can be inserted from the soldering side of the printed circuitboard and penetrate through a recess through the printed circuitboard. The purpose of the invention is to provide a contact device which can be applied together with the components from one side of the printed circuitboard by way of an automatic equipping machine. Accordingly, at least one plug receptacle forms the contact device. The plug receptacle includes two flanks which serve for mechanical and electrical fastening to the printed circuitboard and between which a plug tongue is arranged for contacting the respective countercontact of the plug.

To this end, a freely accessible cutout into which the filler member can be introduced in two use positions is provided in the edge region of the deposit trough.

Abstract: A telephone subscriber station with a lower housing component on which there are pivotably mounted a chassis, which contains all the main components of the subscriber station, and the upper housing component. The chassis, which is mounted so that it is displaceable in the horizontal plane, is fixed in both the vertical and horizontal planes. For this purpose the upper housing component possesses a projection which, when the station is in the assembled state, presses on a spring-like lug of the chassis in the vertical plane. The chassis is also provided with an operating array which engages a recess in the upper housing component. By displacing the chassis in the horizontal plane it is possible to introduce the operating array into the correct position in the recess.
