    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: A reusable mandrel for use in a plate cylinder of a printing press. The reusable mandrel includes two semi-cylindrical shells spaced slightly apart to form a tube having two opposing longitudinal slots. Disposed inside the tube is a controller that may be activated in order to selectively adjust the diameter of the tube. The tube is preferably set at an initial diameter so that the tube may incrementally accept plate material from a supply mandrel. Thereafter, the controller may be activated in order to decrease the diameter of the tube so that the tube may be removed from a spool of used plate material.

A pair of magnetically-permeable elements (22) on the housing magnetically-interact with the sensing mass so as to bias the sensing mass towards a first position within the passage; and a first and second pair of stationary beam contacts (30) project into the passage so as to be bridged by respective electrically-conductive circumferential surfaces (28) on the sensing mass when it moves to a second 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. A pair of horizontally-wound coils (36,38) provide both test and reconfiguration functions.
