Abstract: Shielded electrical cable of the high voltage type having a central conductor with a semiconducting coating surrounded by polymeric insulation, has a shielding assembly that includes a semiconducting layer around the insulation and a multiplicity of aluminum wires which can be grounded, which are individually coated with semiconducting material, and which are arranged in a long helical wrapping around the coated insulation in relatively close spacing to each other. This structure, especially useful underground, provides very effective shielding and fault-current return paths, with a relatively inexpensive aluminum structure that is nevertheless protected from corrosion. There are also advantages of better mechanical protection and less likelihood of cable damage by differential temperature expansion effects.

Abstract: A method of making aluminum alloy parts having high wear resistance, comprising incorporating, in an aluminum premix powder, a minor proportion of particles of an additive alloy of cobalt or nickel containing a relative hard Laves phase intermetallic in a relatively soft matrix, and sintering the resultant mixture under conditions for effecting controlled diffusion of the additive alloy. The premix powder may be a mixture of a major proportion of aluminum with a minor proportion of one or more alloying elements; in particular, the premix may contain a minor proportion of magnesium. To achieve properly limited diffusion, the sintering step is performed at a temperature lower than that employed to sinter the premix powder when the additive alloy is not present.

Abstract: This structural member is an elongated extruded part having a cross-sectional contour including a stitching leg adapted to be deformed together with the margin of an adjacent panel, so as to connect the member and the panel. The structural member disclosed is channel-shaped and has two stitching legs, one on either side of the channel. Each stitching leg cooperates with a wall of the channel to define a slot for receiving the margin of a panel. After the panel margin is inserted in the slot, the stitching leg and the panel are deformed together to connect the panel and the member. Two extruded structural members may be connected with two panels to form a box beam of hollow rectangular cross-section. Other polygonal cross-sections may be formed by connecting alternate extruded members and panels, with appropriate angles at their interconnections.

Abstract: A sheathing system is provided for covering structure of a building. The system includes elongated panels that can be arranged edge to edge to form a generally planar surface which can be moisture tight for convenient washing. The panels are rigidly supported from the building structure so that said generally planar surface does not move if subjected to the pressure of a jet of water. The panels can run transversely to rigid elongated stringers which are spaced from the building structure so that they can clear irregularities on the building structure. Between such stringers and the building structure are spacers that are of relatively short length measured along the lengths of the stringers, and that can slide along the stringers to suitable locations for connection to the building structure. The spacers may be rigid spacers.

Abstract: In production of sintered bodies of particulate metal, especially porous sintered bodies, from particles of metal having a refractory oxide coating, a minor proportion of a flux is mixed with the particulate metal before sintering to aid in removing oxide from surfaces of the metal particles. The particulate metal may be aluminum, with which there may be mixed a minor proportion of particles of an alloying element. The flux may be a mixture of potassium fluoaluminate complexes; the residue of this flux, after sintering, provides a coating that aids in protecting the sintered article against corrosion.

Abstract: A package made of metal foil or light-gauge sheet, having a bottom and lid each lined internally with a lacquer and heat-sealed together by means of the lacquer to provide a sealed, sterilizable, shelf-stable container for food or the like, which does not require refrigeration for storage. The lid is manually peelable from the bottom, with defoliation of the lid lining along the locality of the seal, providing a neat and attractive appearance for the opened container. Specifically different vinyl resin based lacquer systems may be employed for the bottom and lid linings.

Abstract: A sealable and sterilizable package having a bottom of metal foil or light-gauge sheet with a thermoplastic lining and a lid of metal foil or light-gauge sheet with a thermoplastic lining sealingly adhered around its edge portion to the bottom lining to provide a fully sealed, sterilizable and shelf-stable container for food products or the like. The lid is manually peelable from the bottom, with defoliation of the lid lining along the locality of the seal, providing a neat and attractive appearance for the opened container. The lid lining is constituted of a material that effectively and reliably adheres to the metal surface of the lid at sterilization temperatures while forming with the bottom lining a complete but peelable seal.
