Abstract: A vehicle transporter has an elongate vehicular frame with vehicle support members movable between different elevations relative to the frame. Respective telescopically-movable fluid power cylinder assemblies interconnect respective ones of the vehicle support members with the frame to selectively raise and lower the vehicle support members by telescopic movement of the cylinder assemblies. Each cylinder assembly has one or more respective locking members for preventing telescopic movement of the cylinder assembly in a lowering direction, to enable the cylinder assembly to support a respective vehicle support member independently of any fluid in the cylinder assembly. A remote control system is connected to each of the locking members to control its locked and unlocked positions. The locking members are movably mounted on a respective cylinder of each cylinder assembly.

Abstract: A tie-down method for securing a vehicle to a longitudinally-extending elongate vehicle transporter utilizes a vehicle support assembly and at least four securement devices associated with the vehicle support assembly and attachable to the vehicle. A respective tension member portion is interconnected with a respective one of each of the four securement devices. Each tension member portion is capable of exerting a pull-down force on a respective one of the securement devices. A tension-applying mechanism is interconnected with each tension member portion to adjust the pull-down force on each of the securement devices. A tension-equalizing mechanism is interconnected with each tension member portion and is capable of automatically substantially equally distributing tension applied by the tension-applying mechanism among each tension member portion, to substantially equalize the pull-down force automatically with respect to the four securement devices.

Abstract: A dental chair attachment for supporting an implement such as a light assembly, a hand piece delivery device or other device. The attachment is arranged for the pivotal movement of the implement about a supporting post.

Upper and lower collar bases secured to the post support an inner sleeve that has an internal diameter larger than the diameter of the post. An outer sleeve which supports the pivoting member is rotatively mounted to the inner sleeve. The pivoting member including the outer sleeve, as it pivots, does not contact the periphery of the supporting post. Resilient rings of the upper and lower collar bases are forced radially inward against the periphery of the post to secure the attachment to the post.

Abstract: Seed cotton is carried by an airstream into an upright cleaning chamber. Dust and fine trash is carried off through a fine screen in the top of the chamber. The airstream carrying the seed cotton into the chamber will lack sufficient strength to carry the cotton to the fine screen through which the dust and fine trash is carried. The air is separated from the dust and fine trash in a cyclone separator. Larger trash is blown through or carried through a grid on the side of the chamber. The cotton falls to the bottom of the chamber and is carried off with a majority of the air. The fine trash and coarse trash are dropped into a conveyor to be removed.

The entire assembly may be secured together with a minimum number of securing elements, such as bolts, or the like, thus greatly facilitating both the installation and removal of the assembly.

Abstract: A packaged lumber-dipping apparatus comprises a dipping tank of lumber-preserving fluid, a submersible roll case section supported by a hoist mast for lowering a package of lumber into the tank, and infeed and outfeed conveyors. A clamp is mounted on the hoist mast for clamping the package down on the roll case section so that the lumber will not float when submerged in the tank. The infeed conveyor is positioned at an end of the roll case section for feeding a package of lumber lengthwise onto the roll case section. The outfeed conveyor, positioned alongside the tank, receives the package of lumber from the roll case section after dipping. Two tiltable skate roll sections in the roll case section, connected by chains to the clamp, tilt toward the outfeed conveyor when the clamp is raised to unload the package onto the outfeed conveyor after dipping.

Abstract: A tufting machine having opposed loopers for forming a variety of tufted fabrics is disclosed. A needle passes a yarn through a backing and a loop pile looper engages the yarn to form a loop. A cut pile looper is angled down so the bill of the cut pile looper is aligned with, adjacent to, and above the bill of the loop pile looper. In this position, the yarn can be tightened to cause the loop to transfer to the cut pile looper and be cut, or the yarn can be left slack so the loop will be released and remain as a loop. The backing fabric is angled up immediately past the needle, allowing space for operation of the cut pile looper, and assisting the loop to move out of the vicinity of the loopers.

Abstract: An apparatus for enrobing discrete objects. The device includes a perforated drum adapted to receive and tumble a charge of discrete objects to be coated and which is rotatable about its horizontal axis. The tumbling charge is periodically wetted with coating material and is dried by a stream of selectively conditioned air passed through the charge. During the initial phase of each drying operation a high velocity conditioned air stream employing a high percentage of reconditioned air is employed that effects rapid drying without deleteriously affecting the surface of the coated objects. During the final phase of each drying operation velocities are reduced and higher percentages of unrecirculated conditioned air is employed to assure continuity of drying with a concomitant production of an optimum surface of coating material thereon.
