Abstract: A sheet metal processing plant includes a conveyor defining a receiving surface for a workpiece and a conveying direction in a conveying plane and being embodied for conveying the workpiece, the workpiece having a bottom side and a top side, and a turning unit embodied for turning the workpiece received on the receiving surface from the bottom side to the top side. The turning unit includes a manipulator embodied to lift the bottom side of the workpiece off the receiving surface, to perform a turning operation of the workpiece and to place the top side of the workpiece on the receiving surface of the conveyor.

Abstract: A liner for a sport boot shell and a method for making a custom fitted liner for a sport boot, are disclosed. The liner is designed to be worn inside a boot shell. In a preferred embodiment the liner includes inner and outer of flaps which wrap in opposite directions across a wearer's shin and forms a compound curve in a region in front of the wearer's ankle. The liner including flaps may be made from a single piece of thermoplastic foam material of uniform thickness. The design of the liner prevents the cuff of the liner from loosening around the wearer's shin and calf when the wearer's leg is flexed forward at the ankle. The shell can therefore be worn more loosely than is necessary with a boot liner of conventional design. The liner may be made by making an unfitted liner from a sheet of thermoformable material. The unfitted liner has a forwardly facing opening and wings extending forwardly on either side of opening.

Abstract: An optical transmitter for converting a thermocouple voltage into an optical pulse train and a low pass input filter are contained in respective spaces in a soft magnetic housing. The input filter is in lead wires from a thermocouple whose hot junction is embedded in the tip of the insulator of a spark plug of an internal combustion engine. The housing itself forms part of or is connected to the H.T. lead to the centre electrode of the spark plug. The housing is surrounded by insulating material which is itself surrounded by an earthed screening casing. The low pass filter is symmetrically constructed, both electrically and mechanically.The filter prevents interference from reaching the circuitry of the optical transmitter and the housing and the casing prevents the generation and transmission of radio interference.

Abstract: In a spark plug with center electrode and body electrode in which the cylindrical center electrode comprises in its end face a blind bore in which a pin-shaped small-volume noble metal insert is inserted and fixed by upsetting, it is provided that the front region (1a) of the center electrode (1), provided with end-side bore (2) and insert (3) disposed therein, is reduced radially over almost the entire length of the bore (2), the reduced region (1a) having a constant diameter, and that a further pin-shaped small-volume noble metal insert (5) is fixed in a bore (4) formed coaxially with the bore (2) in the body electrode (6). The production of the spark plug can proceed from commercially usual spark plug parts made on conventional production machines; the noble metal insert of the spark plug is securely attached in the center electrode and the body electrode part opposite the noble metal insert has a reduced burnup, thus increasing the life of the spark plug.
