Patent JP-H0679954-B2 (JP)
IPC: B65H29/28
Filed: 1987-06-03
Abstract: The invention relates to a back-edge stop in the form of a cross-member for sheet stackers of sheet-fed presses having a vertically positionable intermediate stacker which forms a relatively large stack, the cross-member being pivotally connected to the sheet brake by way of a link parallelogram support. A sheet brake has disposed on it fixed sheet stops and at least one further fixed sheet stop having a recess in which a brush is pivotally mounted, the bristles of the brush being inclined forwardly and downwardly and extending into the major surface of the stack a distance substantially equivalent to the difference in sheet size. As the intermediate stacker rises and falls, the brush is pivoted, by way of an inclined cam surface on the cross-member, this surface being connected non-positively to engage an actuating edge of the brush to make a controlled pivoting movement around a horizontal axis extending transversely to the direction of sheet movement.

Abstract: A rotary head type recording and/or reproducing apparatus is so arranged as to be able to record on and/or reproduce from a recording track on a recording medium a time code which is not synchronized with the revolution of a rotary head, whereby even when the revolution period of the rotary head is special, the edition of the recording medium can be made with high accuracy and a track exclusively required by the time code becomes unnecessary. Also, a surplus calculating circuit for calculating a surplus when a number is divided by a divisor is disclosed, in which the surplus can be obtained only by the addition without carrying out the division in practice. Accordingly, time necessary for such calculation can be reduced and the scale of circuit arrangement can be miniaturized.

Abstract: In the method for partially restoring a sewer (12) buried in the ground, a fibre mat (19) which covers the damaged zone of the sewer (12) on the inside and is impregnated with curable resin is placed around a hose-shaped support (6) of a packer, which support can be deformed by means of pressure. The external diameter of the support (6) is considerably smaller than the diameter of the sewer to be restored. The length of the support is larger than the wound fibre mat. The resin-impregnated fibre mat layer which is located facing the hose-shaped support (6) is fixed on the hose-shaped support by increased frictional engagement. During the increase in the diameter of the fibre mat winding, which is carried out by inflating the hose-shaped support, the hose-shaped support is rotated with the fibre mat winding, and the fibre mat layers are pressed against one another during the enlargement of the diameter of the winding. The resin which is displaced in consequence is then pressed into cracks (10) and into other damaged points in the tubular section of the sewer which is to be restored. A fibre-free resin ring is formed on the ends of the cladding. <IMAGE>

Abstract: A rotational indexing base curve deposition array for assembling contact lens base curves and front curves with a prescribed and programmable angular orientation to produce a contact lens having a selected axis placement therein, such as a toric axis for a toric contact lens. An array of front curve molds are arranged in a support pallet with a dosed amount of monomer mixture deposited into each of the front curve molds. An array of deposition tubes, positioned in a support plate and coupled to a vacuum source, is used to pick up and support an array of base curve molds. Each of the deposition tubes is then angularly rotated in to the support plate to a selected angularly indexed position therein. A common angular rotational drive is coupled to each of the deposition tubes in the array to angular index each of the deposition tubes to a precise angular position in the support plate. The common angular rotational drive is driven by a stepper motor which can be controlled in a programmable manner to change the selected angularly indexed position. The stepper motor drives moveable racks, which drive pinion gears around the deposition gears. The angularly indexed array of base curve molds is then assembled over the array of front curve molds to produce toric lenses having first and second optical surfaces which are precisely angularly indexed relative to each other.
