Title: Manual damper motor control
Inventor: PATTON PAUL B
IPC: G05D3/12
Filed: 1991-01-24
Granted: 1995-10-31
Abstract: The position of the power output member of a motor actuator which is normally controlled by a microprocessor in response to system-supplied condition signals may be set manually by providing a manually controlled selector signal to the microprocessor allowing manually controlled adjustment signals rather than the normal condition signals to form the parameters from which is derived the motor control signal  In the preferred embodiment, a first switch generates the selector signal and a second switch generates the adjustment signal.  Such apparatus allows a repairer or installer to adjust a mechanical positioning system driven by the motor actuator while the positioning system is in a variety of precisely selected positions.          This control system system contains a feature allowing one to change position of the motor actuator's power output member either continuously or incrementally by appropriately manipulating the switch which generates the adjustment signal.

Title: Process and apparatus for conditioning ozone gas recycle stream in ozone pulp bleaching
Inventor: JOSEPH JAMES C
IPC: D21C9/18
Filed: 1992-05-20
Granted: 1997-02-25
Abstract: A process for conditioning an ozone gas recycle stream in an ozone pulp bleaching process, wherein the level of carbon dioxide in the recycle stream is controlled to allow full capacity operation of the ozone generator. Carbon dioxide concentration is identified over the relevant operational ranges and maximum concentration is identified for full capacity/optimum efficiency operation.  Specific methods are described for controlling carbon dioxide concentration including purging a portion of the recycle stream, counter-current scrubbing of the recycle stream with an alkaline solution and passing the recycle stream through an adsorbent material. Contaminants entering the system also may be reduced by directing the purged recycle stream, which is relatively oxygen rich, into the dewatering press where pulp consistency is increased.  In this manner nitrogen surrounding the pulp is displaced by oxygen and thus, does not enter the bleaching/ozone system with the pulp.

Granted: 2001-05-08
Abstract: In one embodiment, a vertical MOSFET is formed having a lower gate portion (124) overlying the channel region of the MOSFET and separated from the channel region by a thin gate oxide layer (90) . An upper gate portion (120) is formed overlying the drain of the MOSFET and separated from the drain by a relatively thick oxide layer (86). In this particular embodiment, since the dielectric thickness between the upper gate portion (120) and the drain (82) is relatively large, the MOSFET exhibits a lower gate-drain capacitance (CGD) value, while the threshold voltage of the MOSFE T remains relatively unchanged. The upper gate portion (120) may be electrically connected to the lower gate portion (124) or may be electrically isolated from the lower gate portion (124). A preferred method of forming the resulting MOSFET havin g this lowered CGD allows the source (92) and body regions (88) to be precisely aligned with the drain edge of the low er gate portion (124).

Title: Corrugated pallet leg and method
Inventor: BECKWAY BRUCE C
IPC: B65D19/00
Filed: 1993-12-21
Granted: 2004-08-10
Abstract: There is disclosed an improved corrugated pallet having pallet legs attached at various points of attachment. The field of invention relates to a corrugated cardboard pallet of the type generally formed by a pair or more of pallet decks which are stacked atop one another, each of which has finger elements die cut therein radiating outwardly from a central circle and terminating on a circular score line of substantially the same diameter as the inner diameter of one of~the leg elements. The die cut lines for the fingers radiate tangentially outwardly to create a substantially spiral pattern. The leg assembly is of the type formed by an outer leg, and an inner leg, with the radiating die cut fingers nested between the annulus created between the outer and inner leg and adhesively secured to the legs. The improvement consists of die cutting a series of linearly aligned perforations along the length of each finger, such that when the adhesive is applied to the outer and inner surfaces of the fingers, the adhesive is permitted to permeate the inner confines of the corrugated material forming the fingers thereby increasing the surface area of adhesive for securing the finger elements to the respective leg elements.
