Appl. No.:

10/109449

Inventors:

Ronald F. Goodnow - Leicester MA
Robert A. Reid - Charlton City MA
Allen J. Brauns - Sturbridge MA

Assignee:

Kadant Web Systems, Inc. - Auburn MA

International Classification:

D21G 300

US Classification:

162281, 162272, 1525651

Abstract:

An apparatus for doctoring a roll surface including a pivot bar adapted to be mounted on a doctor back and which the pivot bar defines an upwardly projecting fulcrum. A first shelf projects forwardly beyond the fulcrum and a top plate pivotally supported on and projecting forwardly beyond the fulcrum overlies the first shelf. The top platen is held downwardly against the fulcrum. Blade support members are carried by and cooperate with the top plate to define forwardly open slots, which slots are configured and dimensioned to receive a rear edge of a forwardly projecting doctor blade. The blade support members have rearwardly projecting second shelves underlying the first shelf and a loading mechanism is interposed between the first and second shelves for pivoting the top plate on the fulcrum in a direction urging the doctor blade against the roll surface.

International Classification:

B41F 9/10

US Classification:

101169000

Abstract:

A reciprocating doctor is provided for doctoring the cylindrical surface of a roll rotating about a first axis. The doctor includes a doctor back with a blade holder carrying a doctor blade. The doctor back has journals aligned on a second axis parallel to the first rotational axis of the roll. The journals are rotatably supported in sleeve bearings, and the sleeve bearings are in turn supported by diaphragms spaced along the second axis. The sleeve bearings are fixed axially on their respective journals, and the diaphragms have hub portions surrounding and fixed relative to the sleeve bearings, and peripheral portions surrounding the hub portions and fixed relative to a support structure. The diaphragms are configured to resiliently accommodate reciprocating movement of their hub portions and associated sleeve bearings relative to their peripheral portions and associated support structure. A first operating mechanism serves to rotate the doctor back about the second axis, and a second operating mechanism serves to impart reciprocating movement to the journals and their sleeve bearings along the second axis.

Assignee:

Thermo Electron-Web Systems, Inc. - Auburn MA

International Classification:

B08B 102

US Classification:

1525651

Abstract:

In a pull through doctor blade transfer system, the blade ends are slotted at their working edges. The slots are arranged and configured to accept complimentarily shaped portions of a connecting link used to detachably connect the trailing end of a spent or worn blade to the leading end of a fresh blade.

(1-y-y'-y") Sn. sub. y Zr. sub. y' Hf. sub. y" O. sub. 3, wherein x, x', x" and y, y', y" represent mole fractions of the divalent and tetravalent cations and x and x' have independent value greater than 0. 01 and less than 0. 3 and x", y, y' and y" have independent values greater than zero and less than 0. 3, such that the sum (x+x'+x") is greater than 0. 01 and less than 0. 4 and the sum (y+y'+y") does not exceed 0. 4. Regardless of the specific composition selected, the products of the invention have a mean primary particle size in the range of 0. 05 to 0. 4 microns with a very narrow particle size distribution. The products are dispersible so that the mean particle size determined by image anaylsis and by sedimentation are comparable.

International Classification:

US Classification:

371 68

Abstract:

A fualt-tolerant computer system provides information transfers between the units of a computing module, including a processor unit and a memory unit and one or more peripheral control units, on a bus structure common to all the units. Information-handling parts of the system, both in the bus structure and in each unit, can have a duplicate partner. Error detectors check the operation of the bus structure and of each system unit to provide information transfers only on fault-free bus conductors and between fault-free units. The computer system can operate in this manner essentially without interruption in the event of faults by using only fault-free conductors and functional units. Arbitration circuits of unusual speed and simplicity provide units of the computing module with access to the common bus structure according to the priority of each unit. The units of a module check incoming and outgoing signals for errors, signal other module units of a detected error, and disable the unit from sending potentially erroneous information onto the bus structure.

Inventors:

Robert Reid - Dunstable MA

Assignee:

Stratus Computer, Inc. - Marlboro MA

International Classification:

G06F 938

US Classification:

364200

Abstract:

A digital data processing apparatus utilizes a common bus structure for transferring information between functional units, including a processing unit, a peripheral control unit, and first and second memory units. Unit-to-unit information transfers are executed on the bus structure by pipelining signals representative of a transfer cycle that occurs during plural timing intervals and includes plural phases, where the phases of one cycle are non-overlapping and occur in sequence in different respective timing intervals of the transfer cycle. A signalling element periodically generates a first signal indicative the necessity to refresh at least one dynamic memory element in the first memory unit. A memory refresh element normally responds to that first signal for executing a memory refresh cycle during at least one timing interval common to first and second pipelined transfer cycles. A signal is generated indicating the onset of the memory refresh cycle.
