Title: Inking unit attachment for lithographic printing  machine
Inventor: HOVEKAMP JOHN C
IPC: B41K1/42

Abstract: INKING UNIT ATTACHMENT FOR LITHOGRAPHIC PRINTING MACHINES                 ABSTRACT OF THE DISCLOSURE         An inking-unit attachment for a printing press includes a fountain roller, a ductor roller for rocking movement between the fountain roller and a receiver rolled, an idler roller in the nip between the receiver roller and an oscillator roller, and a pair of form rollers for trans-ferring ink from the oscillator roller to the plate cylinder of the printing press.  The receiver and oscillator rollers rotate at different peripheral speeds to provide a skidding action between one or both of such rollers and the idler roller to provide an even distribution and an increased quantity of ink to the oscillator roller.  A three-function cam serves to reciprocate the oscillator roller in an axial direction, rock the ductor roller between positions in engagement with the fountain and receiver rollers respec-tively, and intermittently to drive the fountain roller.          The form rollers are movable between a position in the nip between the oscillator roller and plate cylinder, a position spaced from the plate cylinder and engaged with the oscil-lator roller, and a lift position spaced from both the plate cylinder and oscillator roller.  The inking-unit attachment is adapted to be releasably hung on the frame of the print-ing press, and to be driven from the plate-cylinder gear on the printing press through a shaft affixed to the plate-cylinder frame, where the shaft has an overload clutch to guard personnel from injury and the unit from damage.  The form roller has positioning and adjusting means to permit its spacing with respect to the plate cylinder, indepen-dently of the attitude and position of the inking unit.  The construction of the unit permits the isolation of the ink-carrying members and mechanism requiring lubrication, where-by contamination of the ink is minimized; the structural integrity of the unit minimizes ink spatter and misting on nearby objects.  Access covers protect the ink from con-tamination from exterior sources and from exposure to in-cident radiation, and decrease the exposure of operating personnel to the hazard of moving parts.

Abstract: Spiral Fabric Papermakers Felt Abstract A dryer felt comprising a plurality of spiral coils disposed in a common plane and arranged in a side-by-side relationship with adjacent coils being intermeshed and joined together in a hinged relationship by a hinge yarn of non-circular cross section.  During manufacture, the fabric is subjected to a heat treatment under controlled tension to cause the spiral coils, which are normally circular or oval in cross section, to assume the shape of the non-circular stuffer yarns which are typically of elliptical, D-shape, dog bone or two or more rectangular circular cross section yarns with the long side of the stuffer yarn lying in the plane of the fabric.  In this way, the air voids within the fabric are substantially filled by the hinge yarns to reduce permeability, while the flattened spiral coils provide smooth paper-receiving and machine roll contacting surfaces on the resultant dryer felt.

Abstract: ABSTRACT         The invention is concerned with a dismantable joint arrangement comprising only three groups of only two members in each group, the two members of each group being oriented as pairs of spaced-apart parallel members.  The pairs of mem-bers are arranged relative to one another such that the members of each pair cross the members of the other pairs in abutting engagement therewith and any one pair of members has a respect-ive second pair of members interposed therebetween and a respective third pair of members adjoined thereto and interposed between the members of the respective second pair.  At least two dowell-type coupling elements are associated with each pair for positioning the members thereof against those inter-posed therebetween.  The coupling elements are removably inserted in corresponding holes formed at the crossings of the members and are slidably frictionally engaged in the holes so as to be retained therein by frictional force while being slidably removable by the application of manual force.  The members of the respective third pair cooperate with the members of the one pair and the respective second pair to stabilize the relative position of those members and the coupling elements associated with the respective second pair releasably lock the members of the respective third pair in place to thereby pro-vide a rigid and secure joint for all the members.  The joint arrangement of the invention may be easily dismantled by slidably removing at least one of the coupling elements associated with the respective second pair so as to release at least one of the members of the respective third pair and thereby enable the remaining members to be taken apart.

Abstract: CELL-SEEDING INTO FIBROUS   LATTICES BY MEANS OF   CENTRIFUGATION                       ABSTRACT     This invention comprises the use of centrifugal force to introduce viable cells into a fibrous lattice, as well as fibrous lattices that are seeded with cells by the use of centrifugal force.  A variety of fibrous lattices may be seeded by the methods of this invention, such as a highly porous lattice comprising collagen fibers crosslinked with glycosaminoglycan.  Before the centrifugation, a piece of intact tissue is harvested from a donor site. It is treated with one or more substances, such as trypsin or collagenase, to dissociate cells from the tissue.  The cells are then mixed with an aqueous solution to create an aqueous suspension of cells.  A piece of fibrous lattice is placed within a container, referred to herein as a "bucket," that is suitable for rotation by a centrifuge. The aqueous suspension of cells is placed within the bucket, in contact with the lattice.  The centrifuge is then rotated.  Centrifugal force causes the cells, which are denser than the aqueous solution, to be forced into the lattice in a relatively uniform distribution.  By controlling various parameters, cells can be seeded into any desired location within a lattice.

Abstract: Abstract of the Disclosure A microminiature palladium oxide gas detector and its method of manufacture.  The detector  comprises an extremely small coil of extremely fine wire such as platinum which is retained, sealed and insulated with an amorphous ceramic binder.  The detector further comprises a catalyst applied to its exterior surface.  The detector is manu-factured by winding the wire about a mandrel which is desirably molybdenum.  The coil is then coated with the binder composition which preferably comprises reduced chromic and phosphoric acids.  The binder is then cured to retain the coil and the mandrel is removed by etching or oxidation.  The catalyst is then applied which is preferably palladium nitrate in a weakly acidic hydrolyzed solution which has been adjusted to a pH of about 3 with tertiary octyl amine.  The catalyst is then dehydrated and calcined desirably using an automatic electronic pulse controlled machine to precisely adjust and control processing temperatures and times.  When hydrolyzed palladium oxide is used as the catalyst, the processing temperature never reaches the point where the oxide becomes reduced to the metal.
