Patent number: 4484884Abstract: A machine for high rate production of molecularly oriented thermoplastic bottles is disclosed. The machine is of the reheat-and-blow type. A blow molding station simultaneously blow molds article preforms arranged in matrices by modular article carriers for conveying the preforms and articles through the machine. The carriers are designed to retain the preforms throughout all operations of the machine from a preform load station through a thermal conditioning section, a blow molding station, and to a bottle eject station, thereby eliminating the need for other preform transferring apparatus. The article carriers together with the associated conveying apparatus comprise a sufficiently flexible structure that minor misalignments of the carriers with the blow molding mechanism do not adversely affect bottle production. Both loading of preforms and ejection of finished bottles are accomplished by operation upon matrices of preforms and bottles as defined by the carriers and conveyor lanes.Type: GrantFiled: January 25, 1983Date of Patent: November 27, 1984Assignee: Cincinnati Milacron Inc.Inventors: James G.

Patent number: 4485360Abstract: An rf load is matched to an rf source by a matching network having series and shunt impedances connected between the source and load. A network coupled to the load derives a first rf signal responsive to rf energy reflected from the load. Another network responsive to the first rf signal derives plural rf signals, each having an amplitude that is a different function of the magnitude and phase angle of the reflected energy. In response to the amplitudes of the plural rf signals, the values of the series and shunt impedances are controlled.Type: GrantFiled: July 16, 1982Date of Patent: November 27, 1984Assignee: Cincinnati Electronics CorporationInventor: Glen Seward

Patent number: 4483737Abstract: A method and apparatus for plasma etching a substrate, such as a semiconductor wafer, utilizing a multipole surface magnetic field confining within an etching chamber an etching plasma of substantially uniform density throughout its volume. The plasma is produced and maintained by subjecting a gas such as CF.sub.4 to an ionizing discharge within the chamber. Only DC power sources are used for the discharge, so that there is virtually no perturbing radio frequency interference produced. The wafer is consequently easily biased relative to the plasma for controlled fine-scale etching. Low gas pressures permitted by the surface magnetic field result in substantially anisotropic etching of the substrate by dense plasma concentrations.Type: GrantFiled: January 31, 1983Date of Patent: November 20, 1984Assignee: University of CincinnatiInventor: Thomas D. Mantei

Patent number: 4468746Abstract: The interval between first and second events, which may occur in a period less than a nanosecond interval, is determined with a square wave clock source started in response to the first event. The source derives a square wave having a first transition when started and equally spaced succeeding transitions spaced from each other by T/2, where T is the square wave period. A delay network having N taps is responsive to the square wave, whereby (N+1) square waves are derived. The taps are spaced from each other so the clock source square wave is delayed at tap k by kT/n, where n is a predetermined integer greater than 1 and k is selectively every integer from 1 to N. (N+1) memory elements respectively respond to the (N+1) square waves to generate a signal indicative of which half cycle of each of the (N+1) square wave is being derived when the second event occurs.Type: GrantFiled: December 1, 1981Date of Patent: August 28, 1984Assignee: Cincinnati Electronics CorporationInventor: R.

Patent number: 4457688Abstract: A blow molding machine is provided with an external center pin so that blowing is accomplished without introducing a mechanical or rigid member within the preform and/or bottle. To do this, the blowing is done by introducing a fluid, preferably a gas such as air, into the preform to expand it. Outside of the preform, meanwhile, is the subject center pin or center rod which is located on the preform center line (axis) and near the middle of the preform bottom. The rod receives a gate disposed centrally on the bottom of the preform when the preform is expanded by the entering fluid. In this manner, the center part of the bottom of the preform is engaged by the center pin which thereafter keeps the preform on center as the blowing action continues. A process is disclosed of blowing using a compressed fluid alone inside the preform to expand the preform axially against the bias of an external resiliently biased center pin.Type: GrantFiled: February 3, 1982Date of Patent: July 3, 1984Assignee: Cincinnati Milacron Inc.Inventors: James W.
