Abstract: Improved lint-cleaning cotton gin rollers feature protruding end shafts that may be removed and replaced without having to replace the entire roller, thereby saving considerable time and expense. A pair of hub components are configured for installation into respective open ends of an elongated cylindrical tube, and removeable and replaceable shaft components are configured for installation into the hub components. Each hub component may have a recess with a predetermined shape, and each shaft component has a peripheral shape that corresponds to the shape of each recess. The shafts that extend from the ends of hub components may terminate in a wrench-receiving geometry enabling manual rotation of the assembled roller. Each hub component may comprise at least one flange with an outer diameter that matches the inner diameter of the elongated cylindrical tube. The hub components may be configured to receive counterweights for operational balancing.

Abstract: A one-handed, forearm-braced paddle has a blade at one end and a forearm brace at the other interconnected by a central shaft portion. The shaft has a rigid control handle that has a base end fixed to the shaft, and, extends from the shaft to a hand grip portion. The hand grip is shaped to allow a user to clench it, and is thereby radially spaced away from the shaft to further allow the user to apply longitudinal leverage on the blade, or else give the user leverage with the application of a twisting torque on the blade. The control handle is furthermore goose-necked shaped and arching away from the forearm brace so that the user's fingers are relatively unimpeded by any of the shaft, blade, or base portions of the control handle.

Abstract: Methods of producing a multi-ply paper product are provided. The methods comprise applying coagulant and/or hybrid coagulant-flocculant composition to an upper ply substrate disposed adjacent and above a lower ply substrate in an amount such that a portion of the coagulant and/or the hybrid coagulant-flocculant composition passes through the upper ply substrate. Preferably, the lower ply substrate has a greater freeness than the upper ply substrate. The methods of the present disclosure preferably allow for efficient use of RDF chemicals while making use of the innate freeness differences between the upper and lower ply substrates.

Abstract: A device for pulsing the control lines of an HVAC system in order for a user to discover which outside unit is associated with a particular inside unit. Lead wires from the device connect to the control contacts on the thermostat of an HVAC unit. The device is an electrical or electromechanical circuit that can use the power contained within the thermostat or can be battery powered. Once the device is connected, it pulses the control line for the reversing valve, in the case of a heat pump system, or pulses the control line for the compressor, for a cooling-only system. This pulsing creates a loud clicking sound in either case that allows the repair technician to decipher the correct outside unit corresponding to the inside unit without use of a helper.

Abstract: This disclosure is directed to a lubricant composition having improved compatibility with fluoropolymer seals. The lubricant composition includes a base oil and a sulfonate ester. The disclosure is also directed to an additive package for a lubricant composition that provides improved compatibility with fluoropolymer seals. The additive package includes the sulfonate ester. The disclosure is also directed to a method of improving compatibility of a lubricant composition with a fluoropolymer seal disposed in an internal combustion engine. The sulfonate ester improves the compatibility with fluoropolymer seals of the resultant lubricant composition.

Abstract: A device providing a spinning ornamental design is provided. The device includes a fixed post, a spinning unit, and an electric motor. The spinning unit includes the ornamental design and a solar panel. The electrical motor receives power from the solar panel and includes a stator housing attached to the spinning unit and a rotor shaft fixed to the fixed post.

Abstract: A high speed valve has a valve body having a flow passage therethrough, and a poppet disposed within the valve body. The poppet is movable between a first position in which the poppet blocks the flow passage and a second position, and the poppet has a piston connected to a stem at a proximal end of the stem. The valve also has a rotating lever release mechanism adjacent a distal end of the stem.

Abstract: A valve actuation mechanism for a high rate discharge valve has a collet with fingers adjacent a valve member that provides restraint against displacement of the valve member at angularly spaced locations symmetrical about the axis of the valve member. Each collet finger has at least one projection adjacent a first end. The valve actuation mechanism also has a collet sleeve release mechanism with a main body portion having a first end and a second end. The main body portion contains an aperture with at least one land portion that secures each projection of the collet fingers. The main body portion also has an actuation pad at the second end, as well as a hinge mechanism for allowing rotational movement of the main body portion connected to the first end of the main body portion, and an actuation device that contacts the actuation pad.

Abstract: A process that employs hydrolysis of fats and oils as a pretreatment step to prevent or drastically reduce the formation of glycerin decomposition products that occur in systems that use fixed bed or heterogeneous catalysts for simultaneous trans-esterification and esterification of fats and oils to alkyl esters of fatty acids for use as Biofuels, soaps, detergents, solvents or other applications of fatty acid alkyl esters. The pretreatment step is particularly effective for processes using fixed bed catalytic reactors operating at elevated temperatures and pressures sufficient to cause formation of decomposition products of glycerin which is known to be a problem associated with these processes. The pretreatment hydrolysis step allows the formation, separation and recovery of better quality glycerin by-product and minimizing the formation of glycerin decomposition products in the reactors.
