B23P 1500

US Classification:

2989532, 298153, 492 53, 492 56

Abstract:

A paper-making machine includes a traveling substrate and a roll carrying the substrate.

Abstract:

A calender press for use in a paper-making machine includes a top roll positioned adjacent to a nip and rotatable about a longitudinal axis thereof. The top roll has a length and circumferential perimeter. The length extends in the direction of and is longer than the width of the fiber web. The top roll is thermally compensated in a plurality of thermal zones which are adjacent to each other across the length of the top roll, whereby the perimeter of the top roll may be adjusted in a locally adjustable manner toward and away from the nip. A bottom roll is positioned adjacent to the top roll and defines the nip with the top roll. The bottom roll is rotatable about a longitudinal axis thereof and has a length and circumferential perimeter. The length extends in the direction of and is longer than the width of the fiber web. The perimeter is smaller at each longitudinal end of the bottom roll and larger at approximately a midpoint between the longitudinal ends, thereby defining a crowned bottom roll.

International Classification:

D21F 306

US Classification:

1623583, 162205, 100156

Abstract:

A seal used in an air press for dewatering a traveling paper web in a paper-making machine includes a support roll having a cylindrical surface, a belt and felt for supporting the paper web on either side thereof, an arm for mounting the seal, a seal body having a curved outer surface contour for substantially conforming to the curve of the cylindrical surface of the support roll, and an inner surface adjacent to the arm. A leading edge surface intersects with the curved outer surface, the leading edge surface defines the initial engagement with the traveling belt when in an operating position. A trailing edge surface intersects with the curved outer surface. The trailing edge surface defines, with the leading edge surface, the upstream and downstream bounds of the extended nip of the curved outer surface contour of the seal body over the support.

US Classification:

1623581, 34122, 34123, 100153, 1623602

Abstract:

A press assembly for use in a paper-making machine includes a roll, a first air press backing assembly and a second air press backing assembly. The first air press backing assembly and the second air press backing assembly each include an inner wall, an outer support structure and a plurality of inflatable hoses interposed between the inner wall and the outer support structure. The inner wall is positioned adjacent to and defines an air chamber with the roll.

D21F003/00

US Classification:

33700, 1623583, 7386255

Abstract:

A control system for measuring a gap in an apparatus for pressing a traveling paper web as the paper web travels through the gap accompanied by at least one belt or felt, the apparatus including a press apparatus and a support surface defining a gap therebetween. A frame is provided for moveably supporting the press apparatus. An actuator is operatively disposed between the frame and press apparatus for selectively moving the press apparatus toward and away from the support to control the gap size. A transducer is mounted in either the press apparatus or support for producing a signal indicative of the pressure on the paper web as the paper web, belt and felt pass through the gap beneath the transducer. A controller is operatively linked with the transducer for receiving the signal, determining the measure of the gap as a function of the pressure, and causing the actuator to selectively move the press apparatus to control the gap size.

International Classification:

G01V 3/08

US Classification:

324337, 324345

Abstract:

A method of geologic exploration for subsurface deposits includes the steps of: emitting energy below a surface of the earth; sensing a plurality of reactive electro-magnetic waves resulting from the emitted energy; outputting signals from a plurality of sensors to a vehicle corresponding to the sensed reactive electro-magnetic waves; determining position data for the plurality of sensors; generating position marked data corresponding to the outputted signals and the position data; uploading the position marked data from the vehicle to a satellite; and relaying the position marked data from the satellite to a remote analyzing station.
