Abstract: A shaft tapering device having a body block with a transverse borehole through which the shaft to be tapered is introduced. A recess in the top of the body block intersects the borehole, forming an aperture into which a cutting blade extends substantially tangential to the curvature of the borehole. A cradle attached to the body block includes a pair of parallel wing-like members spaced apart by spreaders at each end of the wings, which are pivotably mounted to the body block. Each wing has a notch formed in the upper edge thereof that is semicircular in the deepest part and on pivoting the wings the deepest part of the notches can be substantially aligned with the borehole.

Abstract: An improved lost foam pour box and lost foam casting process wherein the improvements are positioning one or more fluid permeable separators, such as well points, within the contained volume of the box so that the gasses generated in the lost foam casting process can be vented to the exterior of the box by passing through the separators. By positioning the separators within the box, a larger box can be used and more castings can be made within with reduced burn-in and porosity defects in the resulting castings.

Abstract: An improved electrical plug household use to protect household occupants from electrical shocks while inserting or removing the plug from an electrical receptacle. The plug, in general, is a standard household electrical plug with or without a ground prong. The improvement of the present invention is to mount an elastically collapsible electrically insulating hood on the plug surrounding the prongs so that when the improved plug is inserted more than half way into the household electrical receptacle, the extent of the prongs not yet within the receptacle is surrounded by the hood and inaccessible to contact by household occupants, especially children. The hood can be a plastic bellows integrally molded with the body of the plug or the hood can be formed separatly and glued to the body of the plug. The hood can also be a foamed polymer tube section glued to the body of the plug.

Abstract: An improved rotary mace for striking off extraneous transient projections from, e.g., ferrous castings, the mace having a hub, at least one hammer and means for pivotably securing each of the at least one hammers to the hub, the improved means for securing the hammers including an adapter block for the hammers, each adapter block being removably fixedly attached to a peripheral face of the hub and the hammer being removably pivotably attached to the adapter block, e.g., by a clevis. Preferably, each hammer is supported upon a respective adapter block and each adapter block is provided with means for holding resilient bumper means positioned to receive the impact of the pivotable hammer at either maximal pivotable position. The novel adapter block also has secure fastening means for releasably securing the means for pivotably attaching each hammer.

Abstract: Apparatus for collecting a sample of particulate matter from a pneumatic conveyer system. A sample cup is positioned in the stream of gas carrying the particulate matter with the opening of the cup facing the gas stream. A foreshortened hollow duct-shaped collector element is positioned above the cup and aligned therewith. The transverse interior dimensions of the cup and collector are about the same. This positioning of the collector allows the particulate sample to settle into the cup and substantially prevents the sample from being blown out of the cup by the stream of gas which can be a serious problem when the gas stream velocity is relatively high and the collector element is not used. If it is desired to remove the sample cup through an opening in the wall of the pneumatic conveyer, a shield is provided between the collector element and the wall to substantially prevent the sample from being blown out of the cup by the stream of gas as the cup is being withdrawn.

Abstract: Pyridinyloxphenol compounds and derivatives are prepared by reacting a 2(6)- or 4-substituted pyridine intermediate with a hydroquinone reactant and a base, an excess molar amount of base as compared to the molar amount of hydroquinone reactant being employed along with a requisite reaction temperature whereby there is formed no more than 10 mole percent of undesired 1,4-(bis(pyridinyloxy))benzene by-product after no more than about 8 hours. Treatment of the undesired by-product in a similar manner alone or by isolation and recycling in the process also results in substantial conversion of said by-product to the desired mono pyridinyloxphenol compound.
