  • Patent number: 5472040
    Abstract: A continuous casting mold includes a pair of opposed, spaced apart front and rear mold wall members and a pair of opposed, spaced apart side wall members arranged between the front and rear mold wall members. Each of the side wall members includes a pair of opposed side edges, the first side edge of the pair of edges being defined as that portion of the side wall member in contact with the adjacent front mold wall member and the other side being defined as that portion of the side wall member in contact with the adjacent rear mold wall member. Each lateral surface of the sidewall members defines a recess formed in each side edge for providing a clearance between a portion of each side edge and the adjacent mold wall member. Within each recess is disposed a linear bearing assembly which holds the front and side wall members at a predetermined distance and which absorbs clamping forces applied to the front and rear wall members.

  • Patent number: 4629344
    Abstract: A dot matrix print head which has on the side of the print countersupport (1) a print needle adjustment unit (3) with an electromagnetically drivable guide orifice (7) for the print needles (4) on an adjustment element (6). To provide a precise adjustment for the guide orifice (7) with controllable production tolerances, with flat design of the print head in the area of the guide orifice (7), and with easy installation, to provide a changeover for several guide orifices (7), and to define reliable end positions of the guide orifices (7), the adjustment element (6) consists of a guide support (7) mounted in the area of the print needle drive unit (2) and swiveling by means of a play-free joint (8). An electromagnet (15), fastened next to the guide support (7), is mounted on an armature bridge (13) supported in a play-free swivel bearing (14) running crossways to the guide support (7). The armature bridge (13) rests on the guide support (7) by spaced supporting projections (18), (19).

  • Patent number: 4605829
    Abstract: The measuring device is constructed as an oval chain link which upon experiencing load will tend to lengthen so that its long sides move closer to each other; switching devices or other proximity sensing devices respond to this approach to signal, for example, overload.
