Abstract: The present disclosure relates to a passivating contact that includes a dielectric layer constructed of a first material, an intervening layer constructed of a second material, and a substrate constructed of a semiconductor, where the dielectric layer is positioned between the substrate and the intervening layer, the dielectric layer has a first thickness, and the substrate has a second thickness. The passivating contact also includes a plurality of conductive pathways that include the second material and pass through the first thickness, the second material penetrates into the second thickness forming a plurality of penetrating regions within the substrate, and the plurality of conductive pathways are configured to allow current to pass through the first thickness.

Abstract: This invention relates to a method and a device for producing blow-molded plastic hollow bodies. The device is of an enhanced design which avoids the shortcomings of traditional blow-molding technology. The extrusion die according to this invention is adjustable for different settings to produce different, partly overlapping wall thicknesses of the parison blank in order to compensate for the insufficiencies inherent in blow-molding and to obtain a finished blow-molded product with as consistent and uniform a wall thickness as possible, with an overlay, for instance in vertical wall sections, of evenly spaced longitudinal ribs. A technical concept is introduced whereby, as a novel process, the two conventional measures used to achieve a uniform wall thickness in the finished blow-molded hollow body are complemented by an additional, third step which makes it possible to produce containers whose hollow bodies are provided with targeted, intentional and reproducible irregular wall-thickness patterns.

The device is of enhanced design which avoids the shortcomings of traditional blow-molding technology. The extrusion die according to this invention is adjustable for different settings to produce different, partly overlapping wall thicknesses of the parison blank in order to compensate for the insufficiencies inherent in blow-molding and to obtain a finished blow-molded product with as consistent and uniform a wall thickness as possible, with an overlay, for instance in vertical wall areas, of evenly spaced longitudinal ribs (68). A technical concept is introduced whereby, as a novel process, the two conventional measures used to achieve a uniform wall thickness in the finished blow-molded hollow body are complemented by an additional, third step which makes it possible to produce containers whose hollow bodies (60) are provided with targeted, intentional and reproducible irregular wall thickness patterns.

Abstract: A plunger for attachment to a drum reseal cap, the plunger having opposed ends with a handle alone end, resilient fingers at the other end and a sliding cylinder for forcing the resilient fingers in an outward direction to engage the reseal cap.

Abstract: A system and method to shred, transport and reconstruct plastic drums. The drums are loaded into a shredding apparatus that shreds the drums into shreddings. The shreddings are then projected into a compartment in a storage means in a trailer. The loaded storage means is transported to a remote location to be further ground and pelletized for construction into new drums.

Abstract: Drums liners and methods used in the handling of hazardous materials and liquids comprising the use of disposable drum liners having a fitting allowing communication with the interior of the liner for securing the liner to a conventional drum bung hole, said fitting to be used to evacuate and collapse the liner, and a reseal plug attached to the fitting to seal the collapsed liner, said reseal plug having means to accept a plunger. The lid of the drum is removed and the sealed liner is taken from the drum using the plunger attached to the reseal plug. The liner is then placed into a disposal drum made of the same material as the liner and compressed. Once the disposal drum contains a sufficient number of compressed liners, it is removed for incineration or other safe disposal.

Abstract: A safety container having an array of ratchet teeth cooperating with a pawl stop is provided. The cover of the container can only be removed by counterclockwise rotation while the pawl is urged out of engagement with the ratchet teeth.

Abstract: A drum liner locking and locating apparatus is provided for securing a drum liner to a drum. The drum liner apparatus primarily comprises a fitting, a liner, and a non-releasable securing means. The fitting is passed through an opening in the lid of a drum before the lid is attached to the drum. The fitting can only be passed through the opening so that the liner is in a position that the liner can expand to the full size of the drum. After the fitting is in place, the non-releasable securing means fastens the fitting to the drum raising the drum liner to the top of the drum. Consequently, to remove the drum liner, the top of the drum must be removed destroying the drum and prohibiting reconditioning or reuse of the drum.
