Abstract: Disclosed is a method for microwave plasma processing characterized by providing a plasma processing period of time having no radio-frequency voltage applied to the sample stage. Particularly, if the present invention is used for the shaping by etching of the conductive material layer provided on an underlying insulation material, effects such as shortening of processing time and improvement of etching accuracy can be obtained in the case that the radio-frequency voltage is applied only for the period of time for removing the surface oxide film of the portion to be etched, or in the case that the radio-frequency voltage is further applied until nearly the time to initiate over-etching, and, the latter case is also effective for making the side wall of the portion to be etched vertical.

Abstract: An improved electronic control system for glassware forming apparatus having a heirarchy of machine level supervisory controllers (including a machine controller and an operator communications controller), section controllers, and individual mechanism controllers. The mechanism controllers may be dedicated to the control of a variety of functions admitting of automated control, such as servo-control of electrical motors, sequencing of solenoid valves, generating alarm signals, etc. The mechanism controllers include separate control programs designed for their associated forming mechanisms, and are subject to on-off timing control in real time from the section level controllers. In general, the machine controller and operator I/O controller handle set-up, operator modifications during operation, and other "non-real-time"interactions with the mechanism controllers; the machine controller also coordinates the operation of a plurality of mechanism controllers in accordance with machine-level parameters.

Abstract: A machine for making and painting test tubes by painting open-ended tubes and then fusing and severing them to form individual test tubes.Substitutable paint applicators varying in width, adjustable in location relative to the open-ended tubes, apply paint thereto by means of wiping action caused by rotating said open-ended tubes while in engagement with said paint applicators. The open-ended tubes are then individually fused and severed intermediate their open ends to form, from each open-ended tube, two separate test tubes having painted bands of the desired width and at the desired location, including painted bands which are contiguous with the open ends of the test tubes.

Abstract: A cathode ray tube faceplate press having an indexing table rotatable around a column normal to the table and having circular array of female molds concentric with the column. Index speed of the table is optimized by a barrel cam drive cut to provide smooth acceleration and deceleration which can be tolerated by the molten glass in the molds. A cam dwell precisely registers the table work stations avoiding the need for register pins and the delays they introduce. Acceleration and deceleration peak at about the one-eighth and seven-eighths position of the drive cycle following a generally sinusodial form.

Abstract: A multi-part mold assembly molds glass lenses. A cylindrical sleeve between the top and bottom molds has three cut-outs forming three alignment pads on both ends of the sleeve. These pads are preferably equally spaced around the circumference of the sleeve to constrain the top and bottom molds against rotation about X and Y axes which are orthogonal to the direction of closing of the mold. The alignment pads set the closed vertical positions of the molds. A torus on the bottom mold contacts a tapered opening in a removable sleeve insert to position a glass preform which is held by the insert. A torus on the top mold and a torus on the bottom mold bear against a cylindrical inner surface of the sleeve to precisely align the molds in the X and Y directions.

Abstract: In glass production, waste gases are usually produced which still have a residual temperature of 400.degree.-600.degree. C. even though they are normally used for preheating the fresh air for a glass melting furnace. To be able to utilize this residual energy effectively for the preheating of the raw materials for glass production, particularly cullet, the invention proposes to conduct the waste gases through a bunker (19) for the temporary storage of cullet (20) and to heat the cullet mixture (20) to up to 380.degree. C. during this process. According to a proposal of the invention, the cooled waste gases contaminated during the preheating of the cullet mixture (20) are conducted via a wet scrubber (26) before they are returned to the waste-gas duct (17) leading to the chimney or similar.
