Filed:

Dec 21, 1999

Appl. No.:

09/469444

Inventors:

Palliyil K. Subramanyan - Solon OH
Joseph J. Vauter - Middlefield OH
Ronald W. Robinson - Zanesville OH

Assignee:

Federal-Mogul World Wide, Inc. - Southfield MI

International Classification:

G08B 2100

US Classification:

73 7

Abstract:

A method of detecting premature wear of engine bearings in locomotive engine applications includes incorporating bismuth as a tracer element into the liner of bearing metal applied to a rigid metal backing of the bearing. A soft metal overlay free of bismuth is applied over the bearing liner and the bearing installed in the engine. The engine oil is periodically tested for the presence of bismuth. Early detection indicates premature wear of the overlay, enabling corrective action to be taken to protect the engine.

Appl. No.:

5/620563

Inventors:

Ronald L. Robinson - Stow OH

Assignee:

Go-Jo Industries, Inc. - Akron OH

International Classification:

B65D 5500
B65D 4308
B65D 4118

US Classification:

220380

Abstract:

A unique container closure is disclosed which includes a flat top surface, a vertical side wall, and a sloping intermediate wall interconnecting the top and the side wall at an angle to the vertical. Interiorly of the closure are depending, radially inwardly extending reinforcement ribs which are integrally connected to the top surface, the intermediate wall, and the side wall for stiffening purposes. An annular depending rib is also contained on the interior surface of the intermediate wall, and the inner surface of the side wall has a recess, an inwardly extending annular flange, and a further recess adapted to engage a corresponding lip on the container per se. In this fashion the depending flange of the intermediate wall and the internal rib of the side wall will firmly engage the top lip of the container per se, while the unique intermediate wall construction between the side wall and the top surface will prevent inadvertent dislodgment of the lid by coming into contact with the lid of an adjacent container.

Appl. No.:

7/999314

Inventors:

Ronald L. Robinson - Windham OH

International Classification:

F04B 4306

US Classification:

417393

Abstract:

An improved pilot valve construction for use in a fluid and mechanically actuated double diaphragm pump which includes a housing, first and second axially spaced fluid pressure chambers, first and second flexible diaphragms disposed in the pressure chambers and mechanically interconnected for simultaneous reciprocal movement and each defining a flexible wall of an adjacent pumping chamber and a pilot valve projecting axially into the pressure chambers and slidable axially in response to engagement by one of the diaphragms and wherein the pilot valve is provided with one or more axially extending grooves in its peripheral surface. The pilot valve may also be provided with a radially extending projection in its peripheral surface.

Appl. No.:

7/863749

Inventors:

Ronald L. Robinson - Windham OH

Assignee:

Holcomb Corporation - Akron OH

International Classification:

F04B 4306

US Classification:

417393

Abstract:

A double diaphragm pump includes a connecting shaft for interconnecting the opposed diaphragms mounted in the pump body for reciprocal movement relatively thereof and a pilot valve sleeve telescoped over the shaft and movable axially in response to movement of the connecting shaft and having a plurality of axially directed circumferentially disposed recesses thereon for fluid transfer through the pilot valve cavity. A spool valve assembly is also carried by the body in a cavity which is in selected fluid communication with a source of air pressure, the pilot valve, the atmosphere and the pressure chambers of the pump. The pilot valve sleeve also has at least one projecting annular rib which engages the usual O-rings of the cavity in which the connecting rods and pilot valve sleeve reciprocate for assisting movement past the O-rings in response to pressure from the spool valve.

Appl. No.:

8/735643

Inventors:

Ronald Lee Robinson - Windham OH

Assignee:

Holcom Co. - Mentor OH

International Classification:

F01L 3102
F04B 1700

US Classification:

91346

Abstract:

A fluid-driven reciprocating pump includes a housing and a reciprocating assembly defining first and second working fluid chambers. The housing includes an inlet and an outlet for introduction and exhaustion of the working fluid. A valve member slidably moves against a valve surface between a first position, in which communication is established between the first working fluid chamber and either the power fluid inlet or outlet, and a second position in which communication is established between the second working fluid chamber and the same inlet or outlet. The reciprocating assembly includes a rod which moves in response to the introduction and exhaustion of the power fluid into and out of the first and second working chambers. A control valve actuator shifts the valve member between the first and second positions in response to the movement of the reciprocating rod and also urges the valve member toward the valve surface to form a fluid-tight union therebetween.

Abstract:

A method for manufacture of paper or board, in which method an inverted solution of cationic polymer is added to the fiber suspension for providing retention enhancement without over-flocculating fiber stock and destruction sheet formation and/or improving drainage and enhancing or at least maintaining strength of paper or board, An inverted solution has a bulk viscosity of 50-150 mPas at 0.2 weight-% cationic polymer concentration and inverted solution comprises cationic polymer obtained by reverse phase emulsion polymerization of a monomer blend comprising non-ionic monomers, 15-50 mol-% cationic monomers, an optionally at most 50 ppm of a crosslinking agent, and a chain transfer agent, and the obtained reverse phase emulsion of cationic polymer is inverted into an aqueous solution.
