US Patent:

40972577, Jun 27, 1978

Filed:

Oct 12, 1976

Appl. No.:

5/731591

Inventors:

Richard G. Davey - Toledo OH

Assignee:

Owens-Illinois, Inc. - Toledo OH

International Classification:

C03B 3900

US Classification:

65 26

Abstract:

Improvements are provided in glass forming processes of the type wherein hot metal blank molds are employed by using the complementary action of a solid film lubricant layer, of graphite dispersed in a cured thermoset organopolysiloxane, along with an overspray of a lubricating oil.

Appl. No.:

7/107741

Inventors:

Richard G. Davey - Toledo OH
Donald E. Schupbach - Toledo OH

Assignee:

Owens-Illinois Glass Container Inc. - Toledo OH

International Classification:

C03B 716

US Classification:

65325

Abstract:

A gob delivery system for molten glass charges or gobs from a multiple orifice feeder to a plurality of parison molds in which the transmit times of the gobs are held to a minimum. The gob scoops, which initially deflect the gobs into straight troughs, are formed with a spiral curve to impart less of a curve to the charge. The deflectors which receive the gobs or charges from the troughs are also formed as spiral curves so that the gobs will be presented to vertical guide tubes with a minimum of angular distortion to give more consistent loading.

Appl. No.:

7/000257

Inventors:

Richard G. Davey - Toledo OH

Assignee:

Owens-Illinois Glass Container Inc. - Toledo OH

International Classification:

B07C 534

US Classification:

65 29

Abstract:

A glassware production system includes an electropneumatic individual section glass forming machine having a multiplicity of operating mechanisms for converting a gob of molten glass into a hollow glass container. A glass forehearth feeds molten gobs at controlled temperature and weight to the forming machine. Electronic controllers individually and selectively control parameters of operation of the multiplicity of machine mechanisms and the forehearth. Glassware from the forming machine is inspected for manufacturing faults and for identifying each inspected container with its associated mold of origin. The glassware inspection devices provide fault signals indicative of a plurality of differing types of faults, which are thereafter associated not only with mold or section of origin but also with fault cause. The differing types of fault signals are thus coordinated with associated operating parameters of the forming machine and forehearth, and such operating parameters are automatically varied at the machine and forehearth controllers to correct detected faults.

Appl. No.:

6/324904

Inventors:

Randle W. Taylor - Sylvania OH
Richard G. Davey - Toledo OH

Assignee:

Owens-Illinois, Inc. - Toledo OH

International Classification:

C03B 710

US Classification:

65170

Abstract:

An apparatus for spraying an oil-water-air mixture onto a plurality of shear blades adjacent to a glass gob feeder and including a multi-compartmented mixing block, a flow meter in the water line, an oil-water ratio controller, signal means connecting the flow meter output to the ratio controller for actuating an oil injector in response to the water flow whereby a metered quantity of oil-water mixture is entrained with the air in the mixing block and individual spray nozzles are connected to each compartment.
