Abstract: ABSTRACT OF THE DISCLOSURE           A ball valve assembly and method of construc-tion.  The valve includes a one-piece ball and shaft in a valve housing formed of a body portion and an end portion, the body portion being cast.  The body portion has a flow port at a first end thereof and a large opening at a second end thereof, and an elongated passageway is formed in the body portion for receipt of the shaft.  A relatively thick wall portion is disposed toward the body first end and a relatively thin wall portion toward the body second end around the passageway.  The passage-way can be smooth bore or threaded throughout its length.  A scallop may be formed in the relatively thin wall portion extending substantially perpendicular to the direction of elongation of the passageway, the scallop being machined or being formed during casting.  The shaft is inserted through the body portion large opening and through the scallop to and through the passageway, and then the ball is moved so that it is in sealing relation-ship with sealing means associated with the body portion. The end portion is connected to the body portion, and a bushing is affixed in operative association with the passageway threads or bore for supporting and sealing the shaft.  The interfaces between the body portion and the end portion, and between the bushing and the body portion may be welded where a poisonous fluid or the like is to be valved by the assembly.

Abstract: TITLE OF THE INVENTION:                Filament Type Trimmer ABSTRACT OF THE DISCLOSURE:      In a filament type trimmer a filament is wound on a storage spool in a rotating housing and exits through an open-ing in a rim portion of the housing.  When the extending portion of the filament is rotating freely, it extends approximately radially from the housing.  However, when it hits a relatively stationary object, it is deflected rearwardly so as to extend approximately tangentially from the housing.  To avoid high stresses in the exiting portion of the filament, the exit opening is inclined rearwardly so that when the filament is deflected rearwardly by striking an object, it extends in a tangential line of of the spool, thereby avoiding bending stresses at the exit opening.

Abstract: MALLEABLE STOP FOR ENGINE CONTROL ELEMENT          Abstract of the Disclosure In a vacuum motor for opening an internal combustion engine carburetor choke to a vacuum break position, a stop is engaged between the actuating diaphragm and a base member to establish the vacuum break position. The stop is formed of a malleable material which plasti-cally deforms slightly upon engagement -- and thus gradually changes the vacuum break position upon repeated engagement -- to compensate for changes in engine operating characteristics over an extended period of engine operation.

Abstract: P2011. 1 ABSTRACT OF THE DISCLOSURE A fluid flow restrictor for use in a high pressure valve or the like which comprises a series of closely inter-fitting concentric cylinders alternately attached to the valve seat and an axially movable valve plug of the valve. In one advantageous embodiment of the invention, various arrangements of slot openings are formed through the several cylinders. The slot openings may be of any geometric shape, for example, rec-tangular or trapezoidal, and are of sufficient volume to act as expansion chambers for a compressible fluid. The openings of each cylinder communicate with the openings of an adjacent cyl-inder by various overlapping relationships between openings or by viscous friction flow paths between the cylinders to form restricting flow paths therebetween. Axial displacement of the valve plug will move the interfitting cylinders with respect to one another to vary the flow path dimensions between the slot openings of the cylinders. In another specific form of the invention, the interfitting cylinders are slotless, providing a viscous friction flow path between cylinders and expansion chambers above the open ends of each cylinder and between adjacent cylinders.

Abstract: Grapple Head Arrangement Abstract A compact grapple head for use in apparatus such as a logging vehicle is provided.  Prior art grapple heads had a relatively substantial height which put the load input point at a disadvantageous position which in turn decreased the load carrying capacity of the vehicle.  The grapple head has a reduced overall height and utilizes four pivot connections in controlling the tongs thereof. The arrangement of the pivot connections relative to the tongs, an extensible device and an interconnecting link provides an improved load-handling capability both as to maximum and minimum loads.  Each of the extensible device and link is connected between the tongs with one of the pivotal connections connecting both of the tongs and a second pivotal connection connecting both the extensible device and the other of the tongs to the frame.

Abstract: DESTABILIZATION OF SLUDGE WITH HYDROLYZED STARCH FLOCCULANTS     Abstract of the Invention Hydrolyzed corn and potato starches are effective as flocculants in destabilizing dilute as well as thick sludge suspensions.  Potato starch flocculants are equal to, or better than, the synthetic polyacrylamide flocculants in destabilizing sludge suspensions, especially when clarity of the suspension is a significant consideration.          Among the potato starch flocculants which were found to be generally better than the corn starch flocculants, those containing A?PO4 were the best.  Potato starch flocculants are equally effective on oil-removed and no-oil-removed sludge suspensions.
