摘要:
A lubricant for improved performance in glass molding. The lubricant is smokeless, odorless, non-toxic and non-combustible. It is applied infrequently, such as once a shift or less. The lubricant is carbon monofluoride (CF.sub.x).sub.n wherein "x" is about 0.7 or, preferably, above 1.00. Novel methods of application of the lubricant are disclosed.
摘要:
A method and apparatus for increasing the return of discardable containers and associated elements on which complementary identifying indicia are placed on at least two portions of the container, one indicium being on a removable closure means, a second indicium being on another selected area of the container. The consumer may retain the closure portion upon its removal, return the container to a redemption center and subsequently compare and match the closure indicia with the second indicia in a lottery drawing of indicia from like containers returned to the redemption center.
摘要:
An apparatus for providing a uniform thermal history of a free-falling glass gob having a hollow, heat-resistant conveyor tube extending between the point of shear of the molten glass and the desired mold to which the glass is to be directed and having an electrical heating means associated with at least a portion of the tube which may be controlled by a control means to transfer thermal energy through the tube to the glass gobs passing within the tube, the control means being fed information received from sensing means located at selected points along the tube which is activated by infrared rays transmitted through openings in the tubing by the glass gobs, which temperature information is transmitted to the control means and integrated to determine the operation of the heating means.
摘要:
A smokeless lubricant for coating the interior surfaces of glass forming molds to protect them during contact with molten glass and to facilitate release of formed glass products, including an inert fluid carrying medium, a thermally inert chemical compound suspended in this medium and a wetting agent which causes the chemical compound to adhere to molecules of the fluid carrying medium. The method of lubricating glass forming molds with such a lubricant by mixing selected amounts of the chemical compound and wetting agent in the fluid carrying medium to form the lubricant, stirring or agitating this mixture to maintain the compound in suspension within the carrying medium, and flash-heating this lubricant to a temperature sufficient to vaporize the carrying medium and cause the chemical compound to be exploded onto the interior surfaces of the mold to coat these surfaces. An apparatus to perform the above method in timed relationship to the delivery of a charge of molten glass to the molds, having a metering means to assure that an optimum amount of chemical compound is delivered to the carrying medium, a mixer to maintain the chemical compound in suspension within the medium, delivery conduit means to transfer the lubricating mixture to the molds, injecting means to meter a desired amount of lubricant toward the molds, and a heating chamber to flash-heat the lubricant to a temperature sufficient to vaporize the carrying medium and explode the suspended chemical compound with the vapor onto the interior surfaces of the molds.
