Abstract: A disk gripper for gripping an insulating disk, such as a glass disk, at its edge during processing includes a contact device for contacting the edge of the insulating disk and a mechanism for moving the contact device between a contact position, in contact with the edge of the disk, and a retracted position. In a first processing station, a conductive coating is applied to a disk held by the gripper, with the contact device in the retracted position. In a second processing station, ions are generated in a plasma adjacent to the surface of the disk held by the gripper. The contact device is in the contact position in contact with the conductive coating, and a bias voltage is applied to the contact device in the second processing station. The ions are accelerated from the plasma toward the disk by the bias voltage applied to the conductive coating.

Abstract: A substrate processing system includes a processing chamber, a substrate holder positioned in the chamber, a gas source for supplying a process gas to the chamber, first and second ion sources located in the chamber, and a power source for energizing the first and second ion sources. Each ion source ionizes the process gas to produce ions for processing a substrate disposed on the substrate holder. The first and second ion sources include first and second anodes, respectively. The power source energizes the first and second anodes in a time multiplexed manner, such that only one of the first and second ion sources is energized at any time and interactions between ion sources are eliminated.

Abstract: A substrate processing system includes a processing chamber, a substrate holder positioned in the chamber, a gas source for supplying a process gas to the chamber, at least one ion source located in the chamber, and a power source for energizing the ion source by positively biasing the anode and negatively biasing the cathode, the bias in each instance being relative to the chamber. The ion source ionizes the process gas producing ions for processing a substrate disposed on a substrate holder in the chamber. One embodiment includes two such ion sources. In this case, the power source energizes the first and second anodes and the cathodes in a time multiplexed manner, such that only one of the first or second ion sources is energized at any time and interactions between ion sources are eliminated.

Abstract: An oxidation oven for use in the production of carbon fibers from a polyacrylonitrile precursor fiber. The oven has an oven chamber formed by sides and ends. At least one of the ends has a first opening and a second opening. The product passes through the openings for treatment in the oven chamber. The oven is also provided with a first nozzle adjacent the first opening and a second nozzle adjacent the second opening. Each nozzle is effective for discharging air from an air flow pathway into the oven chamber and forming an air curtain at the opening to which it is adjacent. An air bar defines the air flow pathway.

Abstract: A method of producing a textile product has the steps of applying an adhesive coating to a first surface of a backing material having a first and second surface; passing a fluid towards the backing material to form a plurality of spaces through the adhesive and the backing material; and adhering the backing material to a textile fabric.

Abstract: A one piece shroud combined with a stack and preferably a pallet. The shroud includes first and second central panels, first and third lateral panels on either side of the first central panel and second and fourth lateral panels on either side of the second central panel.

Abstract: A method of producing a water permeable, laminated textile product having the steps of applying an adhesive coating to the rear surface of the textile fabric having a front and rear surface, passing a fluid into a portion of the front surface to form a pluality of openings through the adhesive and the textile fabric and adhering a water permeable backing to the textile fabric.

Abstract: A safety floor construction comprising plural floor sections suspended on springs such that each floor section is depressed whenever a person stands on that floor section while in an aisle between carriages. One or more safety switches are mounted on each carriage. The switch actuators engage the floor sections. When a floor section is depressed by a user, the switch is actuated and interrupts the motor drive circuit for the carriages. Thus, the adjacent carriages cannot move.The movable floor is constituted of individual reinforced plywood panels provided at their edges with metal which are contacted by the spring supports. Moreover, the floor panel spring supports are mounted under the rail attached to the sub floor and require no attachment to the panel.

Abstract: A refiner plate clash detection system and method for plate clash detection is provided herein. The system includes a receiver for a first signal having a significant increase in level at at least one distinct predetermined frequency related to the clash and the characteristics of the discs of the refiner. A filter is provided having a passband matched to pass the distinct frequency of the signal to provide a filtered output signal in which the center frequency of the passband of the filter is determined by the formulaf.sub.o =n.SIGMA..sub.Rwhereinf.sub.o is the center frequency (expressed in Hertz) of said passbandn=the number of segments at a given radius, per single disc and.SIGMA..sub.R =the sum of the rotational rates (expressed in Hertz) of the two discs enclosing a given refining volume.The filtered signal is then smoothed. A threshold level is established.

Abstract: Discloses a machine for feeding groups of bottles in case formation in one-by-one fashion onto an outlet conveyor. The machine involves the use of a spacing conveyor interposed between the feed conveyor and the outlet conveyor and channel means disposed over the end of the feed conveyor so as to orient the groups of bottles in side-by-side rows as they were taken from the case. Spacing guides are positioned on the spacing conveyor at an angle so that a row of bottles in side-by-side relation are retained on the spacing conveyor while the foremost row is angled so that the bottles reach the outlet conveyor at different times and can then be carried away one at a time. The spacing guides are angled so that the last bottle in one row is fed onto the outlet conveyor before the first bottle of the next row is fed onto the outlet conveyor. A series of gates are supplied at the end of all but the last channel so that the gates separate the bottles as they are fed onto the outlet conveyor.
