Abstract: A kiln for drying and processing lumber packages is provided. The kiln generally includes at least one end chamber, a drying chamber adjacent to the end chamber, a first lumber conveying line configured to transport the lumber packages in a first direction through the end chamber and the drying chamber, and a second lumber conveying line configured to transport the lumber packages in a second direction through the end chamber and the drying chamber. The conveying lines may be countercurrent or uniflow. The kiln may further include a heat distributor in the end chamber to distribute heat into the end chamber in addition to heat from the drying chamber along the first and second lumber conveying lines. The heat distributor may include a distribution duct receiving heat from a drying chamber distribution duct or a heater inlet duct, a heat exchanger, a radiative heating element, or a combination thereof.

Abstract: An arrow with retractable blades having an arrow shaft with a cylindrical extension extending from a forward end, an arrow tip having a main body with an open rear end, an arrow shaft recess and a cylinder recess sized to receive the cylindrical extension. The main body includes a plurality of longitudinal blade slots with a blade pivotally affixed within each blade slot, with each blade jointly pivotable between a closed position and a deployed position, with a spring within the arrow shaft recess biasing the forward end of said arrow shaft normally rearward. Spaced circumferential ridges on the cylindrical extension engage mating teeth on each blade such that forward motion of the cylindrical extension within the cylinder recess pivots the blades into the deployed position and rearward motion of the cylindrical extension pivots the blades into the closed position, with a threaded cap over the open rear end of the main body maintaining the forward end of the arrow shaft within the arrow shaft recess.

Abstract: Method of manufacture of paint and adhesive of rubber from vulcanized rubber that is reclaimed, becoming a product that provides impermeability, flexibility and resistance to the pellicle by process of reduction to small particles through cracking beater mills, immersed in adequate solvents and recovered in ball mills to which is added products such as dyeing, pigments, asphalts, oils, accelerators, resins, etc., which give to the paint or adhesive its final characteristics.

Abstract: Methods for obtaining an elastomer product capable of absorbing petroleum and its by products including the steps of forming a mixture of waste vulcanized rubber, resin and organic solvent, grinding the mixture in a mill in the presence of manganese to produce a slurry of very small particles of a reclaimed rubber, and drying the slurry which results in porous elastomer particles which are capable of absorbing petroleum and its by-products.

Abstract: A method is disclosed for obtaining a thermoplastic rubber, from raw materials wich comprehend used rubber artifacts, like tires and other rubber products, devulcanized by means of physical, chemical, or physico-chemical process, transformed into an uniform and regular batch, wich is blended to a thermoplastic, thus obtaining a thermoplastic rubber for diversified industrial applications.
