Abstract: An apparatus which has the means to facilitate maintenance of appropriate lubricating oil levels within the engine of a vehicle.

Abstract: In a process for mercerizing cellulosic cloth by treating the cloth with 3-10% caustic solution at the boil in a boilout stage, washing the cloth after treatment in the boilout stage and treating the washed cloth with 20-25% caustic in a mercerizer, an improvement comprises the steps of:(a) collecting overflow from the boilout stage, contaminated with additives used in weaving or knitting the cloth;(b) treating the contaminated overflow from the boilout stage by hyperfiltration to produce a recovered fraction of relatively pure caustic solution and a concentrate fraction containing additives used in weaving or knitting the cloth;(c) washing the cloth after treatment in the boilout stage with the recovered fraction of relatively pure caustic from step (b).

Abstract: A fabric for threaded embellishments is formed of a plain consistent weave having no more than 60 warp threads with a continuous filling thread so as to permit a needle and thread embellishment through the interstices thereof.

Abstract: An air knife is illustrated having an adjustable orifice which includes a flat plate forming a baffle on one side while on the other side a flexible plate is secured along one edge to the circular plenum offering a free edge portion which may be drawn inwardly with respect to the flat plate to form an adjustable opposite side of the orifice.

Abstract: A cutter is illustrated to have a pivoted support for adjusting the angle of cut of a piece of vinyl or aluminum siding which is held in a fixed position in longitudinal alignment.

Abstract: A heated ceiling fan comprising a plurality of blades with heating means in each of the blades.

Abstract: A shipping pallet is formed from a backing member which comprises at least two thicknesses of corrugated material and which has on the edges for a substantial majority of the perimeter folded corrugated material with only a minor portion of the perimeter comprising severed corrugated material. Backing member also defines passageways for mechanized handling.

Abstract: A tenter frame drive is illustrated wherein auxiliary power operated means are provided to drive the sprockets at the entrance end of the chain runs, opposite the main drive at the exit end. The auxiliary drives remove the slack in the chains which normally occurs at the exit end opposite the point of driving engagement of the sprockets in such a fashion as to avoid chattering of the chain and tenter clips while providing for a division of the forces so as to some extent reduce the maximum tension in the chain, and at the same time insure sufficient tension for proper gripping of the web at the entrance end of the tenter.

Abstract: The invention is designed for use with diesel engine over-the-road trucks and periodically extracts a given quantity of oil from the oil pan of the engine and ejects that quantity into the fuel tank for burning along with the regular fuel. In turn, an automatic oil level sensing device continually senses the level of oil in the engine while the engine is running thus insuring a constant infusion of fresh oil into the engine oil supply thereby effectively changing the oil as the vehicle is operated and removing the need for the discrete oil change operation.

Abstract: A loom is illustrated having an oscillating guide roll receiving cloth made on the loom for guiding same to the center wound takeup. Means are provided for oscillating the guide roll which includes a drive roll also driven by the cloth for driving mounting means for the guide roll at a speed differential in order to produce an oscillatory motion determined by the movement of the cloth.

Abstract: A simplified loom beam let off is illustrated which utilizes a brake disc with opposed brake pads for applying uniform tension to the yarn through the loom beam gear. The pads are urged through yieldable force against the disc and such force may be adjusted manually or automatically through sensors responsive to tension in the warp or responsive to size of the build on the loom beam.

Abstract: A process for hanging framed articles utilizing a measuring device which has an elongated support with first and second moveable indicators. The process comprises vertically orienting the elongated support along a wall, moving the first indicator to a position corresponding to the desired placement of the top of the framed item, removing the elongated support from the wall and placing the first moveable indicator on the top of the framed item. The second moveable indicator is moved to a position corresponding to the hanging mechanism of the framed item. The elongated support is then again vertically aligned along the wall and the point for the location of a hanging device is located at the position of the second moveable indicator.

Abstract: A valve which is substantially leak proof and resistant to road soil and grime comprises a collapsible sleeve and a pin member to prevent leakage, but which is effective to permit inflation and deflation upon movement of the pin so as to dislodge an enlarged end portion from contact with one end of the sleeve.

Abstract: A article support for use with a Shipping Pallet having a flange area to interlock between sheets of rigid material, an article locator for positioning of shipped articles and a ledge area associated with each article locator to prevent the article from contamination and causing wear to the rigid material.

Abstract: Body positioning apparatus for aiding the support of a joint of a patient is illustrated wherein a foam block carries a pressure receiving foam element. Such apparatus is useful for positioning the body of a patient during open heart surgery and the like in a pair of spaced leg supports each having a leg support surface which includes resilient thigh and calf support surfaces having a sloping contour for positioning the leg in a rotated position affording access thereto for vein removal. The foam block and pressure receiving foam element may be used separately or with other positioning apparatus.

Abstract: Dumping apparatus is illustrated wherein a novel compound linkage system is employed in which a first link is pivoted to move a receptacle and the like as to be dumped to an intermediate position and thereafter through movement of a second link the receptacle is raised to dumping position, but only after a latch mechanism to positively position the receptacle is secured through a novel lost motion coupling.
