Abstract: In stencil printing, a printing matrix is thermally made in a printing matrix area on a stencil material on the basis of image information representing an image on an original. The printing matrix area is determined according to the sheet size of printing paper sheet. The stencil thus obtained is wrapped around a printing drum and a printing paper sheet fed toward the printing drum is pressed against the printing drum by a pressure member. A memory which is provided on the printing drum side stores information on the area of the printing matrix. The sheet size is compared with the area of the printing matrix based on information extracted from the memory. When the former is smaller than the latter, printing is inhibited and an error signal which advises against printing is output.

Abstract: In offset presses in which the printing cylinder is provided with a tensioning spindle or reel rod the printing plate usually has a hooked edge which is inserted in a gap in the printing cylinder. The printing plate is then wrapped around the plate cylinder for insertion in the spindle within the plate cylinder. The tensioning spindle carries a slot for receiving an end of the printing plate. After insertion of the plate end in this receiving slot partial rotation of the spindle tightens the printing plate. A substantial amount of skill is required to fix a printing plate on a printing cylinder. It is not easy to align the gap in the printing cylinder with the slot in the tensioning spindle. Two hands are usually required. Herein the tensioning spindle end shaft carries a pinion capable of moving a rack associated with it when the tensioning spindle is partially rotated. A spring is installed to oppose the rack movement.

Abstract: Multiple winding mechanisms are disposed within a single cylinder, such as the plate cylinder of a printing press, and are actuable so as to pay out material across different cylinder segments. For example, the winding mechanisms may be differentially geared to cylinder rotation, such that rotation of the cylinder in a first direction advances material from a first winding mechanism across a first circumferential portion of the cylinder to a second winding mechanism; while rotation of the cylinder in the opposite direction advances material from the second winding mechanism across a second circumferential portion of the cylinder (which may, for example, be diametrically opposed to the first cylinder portion) to the first winding mechanism. Alternatively, material advancement may be achieved by means of a dedicated motor rather than mechanical coupling to cylinder rotation.

Abstract: Method and apparatus for leveling or adjusting a power-boat's average angle of bank or list about its roll axis RA regardless of side wind or off-center loading to improve passenger comfort, increase fuel efficiency, and smooth hull passage through waves with reduced pounding. Improved operating characteristics are accomplished by adjusting steering force angle-of-attack of a small fin-rudder mounted under a forward portion of the boat's keel. The boat's heading is maintained by applying an opposite steering force by altering thrust direction of the driving and steering mechanism. Altering thrust direction occurs either by a pilot steering the helm or automatically by adjusting thrust direction independently of pilot steering. In an optional automatic mode, an electronic gravity inclinometer adjusts a fin-rudder servo. An electronic filter processes the inclinometer signal to control the boat's average attitude around its roll axis RA.

Abstract: A method and apparatus for internally damping vibration and impulse within a crankshaft utilizes the mass of high density inserts and an energy absorbing medium. By placing the inserts into bores in the counter balance weights and surrounding the inserts with the energy absorbing medium, the inserts are allowed to "float" within the counter balance weight, achieving a pendulum damping effect as the inertial mass of the insert responds to vibration propagating along the crankshaft in both directions. In one embodiment the energy absorbing medium is solid but flexible material; in another embodiment the energy absorbing medium is viscous fluid. Because counter balance weights are located at different points along the crankshaft, the present invention damps vibration closer to the sources of the vibration than conventional dampers, thus reducing the propagation of vibration throughout the length of the crankshaft.
