Aerodynamic Positioning Device

View page
US Patent:
7905475, Mar 15, 2011
Filed:
Jan 22, 2009
Appl. No.:
12/358202
Inventors:
Daniel A. Pruzan - Redwood City CA, US
Michael R. Mendenhall - Los Gatos CA, US
Patrick H. Reisenthel - Pleasanton CA, US
Daniel J. Lesieutre - San Jose CA, US
Marnix F. E. Dillenius - Palo Alto CA, US
Robert E. Childs - Mountain View CA, US
Assignee:
Neilsen Engineering & Research, Inc. - Santa Clara CA
International Classification:
B42B 2/00
US Classification:
270 5228, 270 5226, 270 5227
Abstract:
The gathering, conveyance, and assembly of printed material utilizing one or more aerodynamic positioning devices in conjunction with binding machinery is disclosed. The aerodynamic positioning device utilizes controlled fluid flow via a series of discretely spaced jets that create a low pressure region beneath a signature dropping from an adjacent feeder. The aerodynamic positioning device allows the binding machinery to operate at high speeds with lightweight and unbalanced signatures while maintaining high-quality production with reduced paper jams.

Internal Combustion Engine Valve Actuation System

View page
US Patent:
47168633, Jan 5, 1988
Filed:
Nov 15, 1985
Appl. No.:
6/798465
Inventors:
Daniel A. Pruzan - Ithaca NY
International Classification:
F01L 134
US Classification:
123 9015
Abstract:
A hydraulically controlled valve train system for improving performance and emission characteristics of internal combustion engines over a wide range of speed and load. A master hydraulic cylinder containing a master piston replaces the valve lifter in a conventional engine and bears against the camshaft of the engine. A slave cylinder hydraulically coupled to the master cylinder has a slave piston coupled to open an intake valve of the engine. A control cylinder is also hydraulically coupled to the hydraulic line and increases the closed volume of the hydraulic line with increasing pressure in the hydraulic line caused by forced displacement of the master piston by rotation of the camshaft. A solenoid under control of a microcomputer dynamically varies the limit of movement of the control piston, and thus of expansion of the hydraulic line volume, thereby controlling the opening and closing, timing and displacement of the intake valve. External control of the microprocessor affords complete control over the operation of the engine, eliminating the requirement for a throttled carburetor.

Impedance Type Ice Detector

View page
US Patent:
59558873, Sep 21, 1999
Filed:
Dec 20, 1996
Appl. No.:
8/770923
Inventors:
Gerald Willey Codner - Ithaca NY
Daniel A. Pruzan - Santa Clara CA
Richard Lawrence Rauckhorst - North Canton OH
Allen Donald Reich - Akron OH
David Bert Sweet - Canal Fulton OH
Assignee:
The B. F. Goodrich Company - Richfield OH
International Classification:
G01R 2722
US Classification:
324689
Abstract:
An ice detector includes a pair of electrodes connected by a pair of leads to a control unit which measures the total impedance between leads to thereby sense and detect the presence of ice and other contaminants formed on top thereof utilizing a comparator circuit. The electrodes are integrated into patch which can be placed at different locations on an aircraft.
