    摘要: A cleaning apparatus designed for use in conjunction with a lithographic printing member associated with a rotary cylinder comprises an elastomeric (preferably foam) roller for making rotating contact with the printing member; a fixed screen; and a brush in rotating contact with the roller and with the screen. The roller may extend axially at least across the imaging region of the printing member (i.e., that portion of the imaging member that actually receives the image to be printed). The elastomeric roller removes imaging debris from the cylinder, while the brush removes from the roller debris that would otherwise accumulate therein. As the brush rotates past the screen, it sheds debris withdrawn from the roller; debris passing through the screen may be collected, for example, in a container or removed from the system by vacuum. The system may also include one or more doctor blades in contact with the roller for removing debris remaining on the roller following its contact with the brush.

    摘要: An accelerometer (10) features a housing (12) having an passage (14) of rectangular cross-section formed therein, and one embodiment the width dimension gradually increases with increasing displacement along a central longitudinal axis (16) away from a first end (24) of the passage. A puck-shaped magnetic sensing mass (26) is located within the passage and oriented so that its magnetic axis extends in a direction normal to a basal surface (18) of the passage. A pair of magnetically-permeable pole pieces (22) extend from a coil (21) parallel to the passage (14) to magnetically-interact with the sensing mass so as to bias the sensing mass towards a first position within the passage. A pair of electrically-conductive nonmagnetic plates (32) on the housing magnetically interact with the sensing mass to damp the movement thereof within the passage. The coil (21) provides both test and reconfiguration functions.

    摘要: A magnetic plate retention system especially suitable for use in retaining a lithographic plate material to a conventional plate cylinder utilizes one or more magnetic retention devices each having a curved surface complementary to the cylinder. When disposed on the plate, the retention devices magnetically adhere the plate to the underlying cylinder.

    摘要: A winding assembly especially suitable for use in conjunction with a system for automated imaging of lithographic plate material, including on-press imaging systems. A feeder spool installed within a plate-support cylinder contains a rolled supply of plate material, which wraps around the cylinder and is received by an uptake spool, also located within the cylinder. The assembly is driven by the same power source used to rotate the plate-support cylinder, and maintains a strong tension along the wrapped material.

    摘要: A system for accepting and winding lithographic plate material around a cylinder adapted for rotation about a longitudinal axis includes supply and uptake spools and an alignment tool for use therewith. The cylinder is hollow, having an interior and an axial opening thereto, and includes means within its interior for selectably engaging supply and uptake spools. The engagement means are in fixed alignment with one another and are disposed within the cylinder so as to define an unobstructed winding path extending around the cylinder from the supply spool to the uptake spool. Plate material stored on the supply spool is extended around this path and affixed to the uptake spool. The tool includes means for releasably gripping supply and uptake spools, and alignment components for aligning the gripping means to at least one engagement means within the cylinder when the tool is introduced therein. The tool is removed from the cylinder following release of the spools to the engagement means.

    摘要: An arm rest assembly is usable with a mouse pad or keyboard and provides vertical support for a user's arm to avoid fatigue and injury. The assembly has at least one forearm cradle and a thin profile which allows a mouse or digitizer pad to be placed on an assembly platen or to insert the assembly under a keyboard and support both forearms of the using while striking the keys of the keyboard with both hands. The assembly further includes a detachable slide which is pivotable and, at the same time, allows linear movement of the arm toward and away from the assembly. An interchangeable cradle for the user's forearm has springs to counteract the arm weight and to make the cradle stable in the horizontal position while permitting some tilting.
