Abstract: A sound damping wallboard and methods of forming a sound damping wallboard are disclosed. The sound damping wallboard comprises a gypsum layer with a gypsum surface having an encasing layer. The encasing layer is partially removed to expose the gypsum surface and form a gypsum surface portion and a first encasing layer portion on the gypsum layer. A sound damping layer is applied to the gypsum layer to cover at least part of the gypsum surface portion and the encasing layer portion.

Abstract: A spreader disk assembly for spreading crop residue such as straw discharged from an agricultural harvesting machine, and more particularly, which has a bat support mechanism that enables the bats to be quickly and easily hingedly or pivotally convertible from a deployed spreading mode to a flattened stowed mode for windrowing, which does not require removal of the bats, or the disk from the spreader. A locking mechanism is provided that enables the quick and easy conversion and securely holds the bats in both modes.

Abstract: Several embodiments of a wedgethread pipe connection are disclosed that have improved makeup, sealing, and non-loosening characteristics. In one embodiment, an open wedgethread is disclosed that has an included angle measured in the gap between the stab flank and the load flank to be not less than zero, so as to prevent premature wedging between mating flanks before the position of full makeup is reached, as does occur between trapped wedgethreads wherein the included angle is less than zero. The invention may be used for pipe threads large or small, as a flush joint, with collars, screwed into plates or it may even be used to reversibly connect such as solid posts to base members where a wide makeup torque range is desired.

Abstract: A control system for controlling a vehicle system at least partly in response to an anticipated condition along the vehicle's course of travel is disclosed herein. The vehicle includes a drive train powered by an engine, and the anticipated condition may affect engine load. The control system includes a location signal generation circuit for receiving positioning signals and generating location signals therefrom, a memory circuit for storing a predetermined geo-referenced map including map data indicative of anticipated conditions along the course of travel which may affect engine load, and a control circuit. The control circuit predicts the anticipated condition using at least the location signals and the map data, generates a control signal based at least upon the anticipated condition, and applies the control signal to the vehicle system.

Abstract: An Integral Self-Swaging Threaded Tubular Connection to connect ends of plain-end pipe or the like without the use of a coupling is disclosed that may be selectively tightened to various positions of make-up to effect strength efficiencies up to 100% with respect to the pipe body. Tapered pin threads (62) are formed on tubular member (60) for sealing cooperation with box threads (63) formed on tubular member (61), the threads being dimensioned such that when they are screwed together power tight, the box is swaged outwardly to a first predetermined configuration as at (90) and the pin is swaged inwardly to a second predetermined configuration as at (91) such that pin wall (92) at the last engaged pin thread and box wall (93) at the last engaged box thread are substantially the same thickness as the nominal pipe wall (94), to thereby effect a full-strength connection.

Abstract: A threaded pipe connection as shown in FIGS. 1, 4, 5, 6 or 7, having a thread form such as depicted in FIGS. 8-11, that has: improved sealing; increased resistance to mechanical loads; easy assembly and low makeup torque. Both pin (31) and box (45) may be cut on non-upset pipe ends and result in nearly 100 percent joint efficiency. Tension flank (33) and compression flank (34) may be formed on pin (31) at high flank angles measured from the tubular axis so as to withstand high axial loads without forcing the pin inwardly and the box outwardly, which would tend to separate the mating threads, break the seal and jump threads. Low torque is assured by the complementary forms of pin threads (32) and box threads (42) which confine the thread dope (49) to remain in the root gaps (52) and (54) during assembly.

Abstract: A threaded tubular connection is depicted (120) for connecting joints of reinforced thermosetting resin pipe. Box threads are formed in both ends the joints as at (107) for connection by means of a coupling (102) formed with pin threads (104) on both ends. The coupling is formed of a material having a more reliable compressive strength than the pipe material, to prevent cracking and shattering of the pipe material upon make-up. A process for forming threads with the pipe joints is disclosed.

Abstract: A high efficiency an integral, non-upset, full strength, threaded pipe connection that has at least one swaged end. A box swage at 81 and 85 or a pin swage at 82 and 88. Thread engagement extends substantially to the bore of the box and substantially to the outermost diameter of the pin so as to prevent reduction of the cross section area of the wall of the joint.

Abstract: A control system for operating one or more different mechanisms on a cotton harvester as a function of engine speed. The control system includes an apparatus for generating a speed signal representative of current engine operating speed and control circuitry connected to the apparatus for controlling operation of at least one and, preferably, a plurality of different mechanisms arranged on the harvester as a function of engine speed.

Abstract: A tapered threaded tubular connection is depicted (20) that is formed and dimensioned so as to prevent cross-threading of pin 4 with box 7 when at stab position as at 54 of FIG. 5. As shown in FIG. 6, the stab depth is sufficiently great such that pin and box thread crests contact as at (47) to thereby limit angular mis-alignment to be less than the angular mis-alignment required to permit pin thread crest (55) to pass box thread crest (56) which is it did pass, would effect cross-threading of the connection.

Abstract: A connection (20) for oilwell tubing and the like is disclosed which has the same outer diameter (21) as does the tubing joints (8 and 9) that it connects. Tubing joints are formed internally with a tapered thread (6 and 7) having a loadbearing flank angle (75.degree. or more) that negates pullout tendency. A mating coupling (2) having external threads (3 and 4) may be provided with a bore 10 so as to clear a driftbar. Coupling (2) may be provided with bore (13) extending from (14 to 15) so as to develop substantially, a 100% joint strength.

Abstract: An air intake system for an agricultural implement having a mobile frame, an internal combustion engine carried by the frame, a heat exchanger defining front and rear planar faces, an engine driven fan and a walled structure enclosing the engine, heat exchanger and fan. The walled structure defines a screened air inlet through which environmental air is drawn upon operation of the fan. An air plenum directs environmental air between the air inlet and the front face of the heat exchanger. The heat exchanger is mounted proximate to the fan toward one end of the air plenum. A bypass channel arranged adjacent the heat exchanger directs environmental air around the heat exchanger and exhausts a downstream of the rear face of the heat exchanger. Foreign material, carried in the environmental air, is likewise directed around the heat exchanger whereby preventing relatively rapid plugging of the heat exchanger.

Abstract: A connection (20) for oilwell tubular joints (8 and 9) to effect a fluid tight conduit wherein one of two cooperating stop shoulders (19) of limited dimension is formed with peaks (22) and valleys (24) such that the peaks contact the other stop shoulder (18) upon full make-up of the connection so as to provide channels (24) for the escape of lubricant from between the shoulders and thereby effect a higher overload torque capacity for the connection, without sacrificing other characteristics of the connection.
