Filed:

Oct 30, 2002

Appl. No.:

10/283861

Inventors:

Gerald N. Shields - Chicago IL

Assignee:

Graymills Corporation - Chicago IL

International Classification:

B41F 340

US Classification:

101364, 101216, 101487, 1525652

Abstract:

An ink cooling system for printing presses is disclosed. The ink cooling system is arranged to cool ink at locations within a printing press at the locations in which the ink properties are most likely to be adversely impacted, and which locations are or may be physically remote from the centralized ink supply or ink tanks. The disclosed system thus counteracts localized heating that commonly occurs in printing presses, thus minimizing or eliminating printing problems caused by heated ink.

Appl. No.:

10/714706

Inventors:

Gerald N. Shields - Chicago IL, US

Assignee:

Graymills Corporation - Chicago IL

International Classification:

B41F 33/00

US Classification:

101483, 101424

Abstract:

An enclosed Flush/Rinse and inking system for inking and flushing printing presses is arranged to ink an anilox roller of a printing press, wherein the ink is dispersed from a centralized ink tank. Once inking is complete, the ink is returned to the ink tank, and used flushing solution is circulated within the printing circuit to clean the press. A final rinse of clean solution is provided to ensure the press is properly cleaned.

Assignee:

Graymills Corporation - Chicago IL

International Classification:

F01D 2524

US Classification:

4152141

Abstract:

A disposable pump assembly adapted to be driven by a motor through an elongated shaft. The disposable pump assembly includes a pump body having a volute portion and an elongated riser portion extending upwardly from the volute portion. The riser portion is integrally joined to the volute portion by a neck defining a restricted opening leading from the riser portion to the volute portion. The elongated shaft is adapted to be inserted into the riser portion, through the restricted and into the volute portion of the pump body. The disposable pump assembly also includes a shaft-receiving impeller disposed in the volute portion of the pump body for driven movement by the motor. The impeller and the elongated shaft each have correspondingly shaped portions for interconnecting and driving the impeller upon insertion of the shaft through the riser portion and into the volute portion of the pump body. The volute portion of the pump body has an inlet opening and an outlet opening from which an outlet tube extends upwardly in spaced parallel relation to the riser portion. With this arrangement, the disposable pump assembly can be formed of a plastic material by a thermoforming or blow molding process in a manner accommodating rapid interconnection of a supply tube and the motor thereto.

Assignee:

Graymills Corporation - Chicago IL

International Classification:

A01G 2509

US Classification:

137899

Abstract:

In order to facilitate the transfer and utilization of a tank of ink in a printing facility, an ink tank/pump system includes a plurality of ink tanks each adapted to accommodate a pump for supplying a press with ink from the tank. The system also includes a transfer cart having a generally flat, horizontal surface to support at least one of the ink tanks thereon. The transfer cart is adapted to move from one point to another, e. g. , from an ink tank storage location to a press location. The system still further includes a receiver cart having a generally flat, horizontal surface to support at least one of the ink tanks thereon. With this arrangement, the tank supporting surfaces of the transfer and receiver carts are alignable, which accommodates slidably moving the ink tanks therebetween, and the ink tanks may include a splash resistant lip.

International Classification:

G01N 1112

US Classification:

Abstract:

A viscosimeter comprising a Zahn cup, a supply tank arranged to supply a liquid, the viscosity of which is to be measured, to the Zahn cup, a control mechanism operable to stop the supply of liquid to the Zahn cup once the latter has been filled to overflowing, and a timing mechanism arranged to measure the time taken for the Zahn cup to empty following operation of the control mechanism. The timing mechanism comprises an emitter-detector pair positioned to direct a sensing beam across the flow path of liquid which leaves the Zahn cup and a timer connected to commence a time measurement at the instant of operation of the control mechanism, and to stop the measurement at the instant the detector of the emitter-detector pair indicates an absence of liquid therebetween. Such a viscosimeter may be used in the measurement of the viscosity of ink used in a printing process, and the control of the viscosity in dependence upon that measurement.
