    Abstract: A tablet splitting apparatus capable of reducing fluctuations in weight of split tablet pieces even with simple advanceable-retractable blades is provided. A holding mechanism holds a tablet to be split at a cutting position. In reducing the gap between a pair of opposed blades, which are advanced and retracted with respect to the cutting position, to cut the tablet, the holding mechanism continuously holds the tablet until the tablet is caught between the pair of opposed blades of a cutting mechanism. After the tablet is caught between the pair of opposed blades, the holding mechanism release the tablet and only the pair of opposed blades hold the tablet. The opposed blades are caused to cut into the tablet after the holding mechanism releases the tablet, preventing a crack caused in the tablet ahead of the opposed blades from being curved or increased.

  • Patent number: 4895057
    Abstract: The known turn broaching of crankshaft main bearings is not suitable for broaching crankshaft bearing pins for the connecting rods because that would require locating the rotational axis of the crankshaft in the connecting rod bearing pins, whereby the crankshaft would rotate eccentrically. The resulting unbalances prevent driving the crankshaft with the r.p.m. required for the turn broaching operation. To avoid this problem a broaching lathe for the rotational or turn broaching of crankshaft connecting rod bearing pins is equipped with a steady rest including a rotating support device which permits mounting the crankshaft in the lathe in such a way that the rotational axis coincides with the axis of the connecting rod bearings of the crankshaft.

  • Patent number: 4784318
    Abstract: Rectangular drawings of standard dimensions or formats can be automatically cut out of a continuous paper or plastic web (1) by a transverse cutter (9) and a plurality of longitudinal cutters (26), as directed by coding (20) on the edge of the web. The cut-off strips (23) of scrap made by transverse cutter (9) are directed away by a movable deflector (13). Additional deflectors (62) are provided downstream, in web motion direction D, of the longitudinal cutters (26) and serve to separate the scraps (23, 25) produced by the longitudinal cutters from the drawing forms (A0-A4) which have been trimmed on all four sides. Thus, manual separation of the drawings from the surrounding scrap is obviated.

  • Patent number: 4538800
    Abstract: To provide for deflection of copy between two respective paths (8, 16; 9, 17) without using switchable deflection tongues, two cylinders (3, 4) have segmental elements (24, 27) located thereon which are respectively, selectively, positionable on or within the circumference of the cylinders, or projecting therefrom, for example by securing the segmental elements in projected position, or by controllable eccenters (28-35). Copy is fed by a belt transport system between the cylinders and, if the copy meets a projecting segment, the projecting segment will deflect the copy into one of the paths, in accordance with the position of guide tongue structure (36). Alternate feed in the respective path can be obtained by offsetting the projecting segments (25, 27) from each other, for example by 90.degree. (FIG. 3) and feeding copy with equal copy length and copy spaces therebetween to the cylinders, so that the copy will be directed, alternately, to one, or the other of the exit paths.
