Abstract: A roof tile support element that fits between roof tiles and a roofing surface to provide support for the roof tiles, which is compatible with a broad range of roof tiles, is adjustable during installation, and that allows individuals to walk confidently on a tile roof without breaking tiles.

Abstract: A clamping system is provided for assembling the wall panels of wooden kitchen cabinets and the like, including a frame that is normally supported for sliding movement on an assembly table toward an assembling position relative to a workpiece arranged on the table. The frame is vertically displaceable between a normal elevated transport position and a lowered clamping position relative to the assembly table, and a normally-activated device prevents displacement of the frame from the elevated position to the lowered position. A first suction cup is carried by the frame for connecting to the frame a panel that is to be fastened to the workpiece, and a second suction cup is carried by the frame that is operable, when the displacement preventing device is deactivated, to connect the frame to the assembly table, thereby to clamp the panel to the workpiece.

Abstract: Combinations of thiopeptin or one of its analogs with a pyromellitic diimide are shown to synergistically increase the feed efficiency of economically important ruminant animals, especially cattle, sheep, and goats.

Abstract: A solvent-bearing sludge material is pumped by a variable speed positive displacement pump from a preparation mixing tank through a pressure responsive valve which distributes the material into the upper portion of an insulated distilling or processing vessel. Steam is introduced into the lower portion of the vessel and mixes with the material to volatize the solvents which are directed through a condenser and pump to a storage tank. Water and suspended solid particles are continuously pumped from the bottom of the vessel to an insulated settling tank where the solid particles settle and are continuously removed by a drag-out conveyor. The hot water in the upper portion of the settling tank is pumped back into the vessel, and may have sufficient velocity to increase agitation within the vessel, or a mechanical agitator may be installed within the bottom portion of the vessel.
