Abstract: Abstract A printing press comprises a frame.  A plate cylinder is mounted in the frame for rotation about a first axis and a blanket cylinder is mounted in the frame for rotation about a second axis.  The plate cylinder and the blanket cylinder have a contact pressure therebetween for printing operation.  A skew eccentric is supported by the frame and is associated with at least one end of the plate cylinder.  The skew eccentric is operable to change the relative angular positions of said first and second axes.  A means is connected with said skew eccentric for maintaining the contact pressure between the plate cylinder and the blanket cylinder substantially unchanged upon rotation of the skew eccentric.

Abstract: Abstract of the Disclosure A connector assembly includes a pin connector for receipt by a box connector.  An external surface of the pin features a helical groove; a generally complementary internal surface of the box features a helical groove of the same rotational sense and pitch.  A helical latch coil is carried in one of the grooves, extending partly out of the groove. The connectors are latched together by stabbing the pin into the box, whereby the latch coil is ratcheted into place, partly extending into the groove of the connector not carrying the coil.  Subsequent mutual rotation between the connectors in one rotational sense tightens the latched connection; rotation in the opposite sense releases the latching.

Abstract: Abstract:          Several characteristics are assigned to the regions of a picture having light and shade and obtained by photographing a surface of an object.  Several characteristics are also assigned to the regions of the picture, which characteristics are extracted on the basis of the results of the first property-assigning operation, and the boundary lines therebetween.  The angles of inclination of these regions and the unevenness of the regions of the surface that are on these boundary lines are estimated by utilizing the relation between the above-mentioned characteristics and the direction in which the light is applied to the object while it is photographed.  The relative elevation of the surface of the object is thus determined.  The above-mentioned characteristics are determined with respect to pictures that have been obtained by photographing a surface of the same object from different positions, and the characteristics thus determined of these pictures are compared to determine the corresponding points.  The quantitative elevation of the surface of the object is then determined in accordance with the principle of triangulation using the corresponding points thus determined.

The amount of fibers is such that the sheet has a voids volume of at least 65°%, preferably about 90%.  The diameter of the pores of the porous sheet are at least about 150 µm such that bony tissue can grow in the pores.  These porous sheets are highly malleable without loss of structural integrity or pore size distribution. Accordingly, the porous metal fiber mesh sheets are useful for stabilizing prosthetic devices or for general repair of defective bone structures.
