Title: Sheet feeding method and apparatus
Inventor: LABELLE THEODORE J
IPC: B65H3/24
Filed: 1990-02-08
Granted: 1995-07-04
Abstract: A sheet feeding method and apparatus particularly suited to handling plastic sheets having a tendency to adhere to each other under electrostatic action, in which the uppermost sheet of a stack is fed by first lifting the rear edge of the sheet into a generally arcuate configuration and translating a lifting member forwardly under the lifted rear edge to progressively separate the uppermost sheet from the rest of the stack.  The lifting members preferably in the form of an idler roller which translates to a position in cooperation with a drive roller so that the sheet becomes sandwiched between the two rollers for final feeding from the stack.  The mechanism features a pick assembly particularly suited for engaging and lifting the rear edge of each sheet into a predictable arcuate configuration.

Title: Boundary layer control rolls
Inventor: GROSS FRANK R
IPC: F26B13/04
Filed: 1992-10-21
Granted: 1995-09-05
Abstract: At least one boundary control roll (62) is disposed adjacent a moving web (18) of paper or like material being imprinted with ink.  The web (18) of paper has opposing planar surfaces (18a, 18b), and at least one such boundary control roll is positioned in transverse non-contacting proximity to a planar surface of said web and rotated counter to the direction of travel of the web.  If multiple rolls are used, the rolls (62a, 62b) on opposing sides of the web (18) should be coacting and counter-rotating.  The boundary layer (BR) formed about the peripheral surface of each roll (62) is adjustably positioned within the boundary layer (BW1) adhering to the moving web.  By colliding the respective boundary layers, a zone of interference is created and the boundary layer (BF) of the web is significantly reduced in thickness.  In this manner, the thickness of the hot solvent-laden boundary layer adhering to each side of the web is effectively reduced.

Title: A process for removal of so2 and nox from combustion flue gases and an apparatus used therefor
Inventor: ZIMEK ZBIGNIEW
IPC: B01D53/74
Filed: 1992-05-21
Granted: 2002-03-05
Abstract: Removal of SO2 and NO x from combustion flue gases is effected to be subjected to irradiation by an electron beam and to the action of microwaves applied in the form of a continuous and/or pulsed stream. The stream of flue gases irradiated by the electron beam in the radiation zone is subjected to the action of microwave energy in the whole cross section of the stream of the flue gases. This results in a decrease in the dose rate "average power of the electron beam" and a reduction in the costs of accelerators while retaining the same removal efficiency. Further, the apparatus for removal of SO2 and NO2 from combustion flue gases is provided in a radiation process in which a stream of accelerated electrons and microwave energy are used simultaneously.

Title: Expansion joint method and system
Inventor: CATHEY JOE RAY
IPC: E01C11/10
Filed: 1993-01-22
Granted: 1997-03-11
Abstract: A method to produce an expansion joint for adjacent roadway slabs having a gap therebetween.  A recess is cut or formed into the surface of each adjacent roadway slab to form a pair of recesses parallel to and adjacent to the gap.  The recesses are cleaned to a sound, dust-free and rust-free surface.  Each recess is coated with a slightly resilient polymer primer to inhibit rusting and corrosion and to form a bonding surface.  A mortar mixture of a slightly resilient polymer and aggregate is installed in each recess to form a pair of parallel nosings adjacent to the gap,  the nosings being bonded to the roadway slabs.   Opposed surfaces of the nosings are primed with a silicone primer.   A temporary backing is inserted in the gap between the nosings.  An initially liquid silicone sealant is installed between the nosings and on top of the temporary backing which will cure to form a flexible seal.

Title: Method and apparatus for controlling coordinate displacements of a platform
Inventor: ENGELSE PETER DEN
IPC: G05B19/421
Filed: 1993-04-29
Granted: 2000-01-11
Abstract: The field of the invention is a combination of a microscope and an interactive image analysis system comprising a camera and a computer work station. The purpose of the invention is to facilitate the interactive control of coordinate displacements of the stage of the microscope. For each coordinate x and y an electromechanical control channel is established. At the input of the control channel two cascaded wheels in a coaxial arrangement and two angle encoders are used as a detached, independent tool which is not kinematically linked to the stage. In the middle of the control channel, the pulses of the angle encoders undergo a non-linear transformation. A processor performs a calculation which discriminates between slow displacements and fast displacements. At the end of the control channel, a flat, easily accessible platform of the microscope stage has two working areas, one for manual previewing and one for interactive scanning of a specimen.

Granted: 1998-04-28
Abstract: Methods of and apparatus are provided for placing a cover lifter at a position at which a cover for a load-carrying vehicle (such as a standard gondola car) must be lifted to form a non-load-formed peak.  A web is quickly installed, and need be installed only at the locations at which there is a valley in the load.  The web is placed transversely across the car generally in the horizontal plane of the top of the car.  The web supports the cover lifter which is initially (during placing of the cover over the web and the loaded car) flat and generally in the plane of the top of the car.  After placing the web tightly on the car, and then securely tying the cover to the car over the web, the cover lifter is raised and causes the cover to stretch in a controlled  manner  and  form  a  lifter-peak,   which  is  a non-load-formed peak at just the location at which the load did not form such a load-formed peak, but did form a valley.
