Abstract: Systems and methods for sterile delivery of prostheses that protect refined and/or conditioned surface properties and thereby reduce aging of surface properties in prostheses. An example of the system includes a partially custom-shaped holder that also serves as an insertion tool that holds a customized dental prosthesis in a pre-defined position inside a titanium container that is hermetically sealed. Container materials serve as a getter or catalyst with respect to the osseoconductive surface. An example of the method includes laser welding to hermetically seal a metal container as packaging for a prosthesis with a metal foil, and the sterilization of the packaged and sealed prosthesis with dry heat.

Abstract: Methods of manufacturing dental prosthesis/implants each to replace a non-functional natural tooth positioned in a jawbone of a specific pre-identified patient are provided. An example method includes the steps of receiving imaging data such as x-ray image data and surface scan data of a dental anatomy and/or a physical impression of the dental anatomy of a specific preidentified patient. The steps can also include forming a three-dimensional virtual model of at least portions of a non-functional natural tooth positioned in the jawbone of the specific pre-identified patient based on the imaging and surface scan data, virtually designing a dental implant based upon the virtual model, exporting the data describing the designed dental implant to a manufacturing machine, and custom manufacturing the dental implant for the specific patient.

Abstract: An apparatus is described which serves for a pyrometallurgical processing of fine-grained solids suspended in high-oxygen gases, comprising a generally horizontally extending cylindrical vessel and a combustion shaft, which communicates with and vertically opens into the vessel which is provided with a gas outlet opening and with an opening for discharging molten material. An almost complete separation of the molten particles is effected in that the mouth of the combustion shaft tangentially opens into the vessel at the entrance of a spiral-shaped entrance passage, which opens into a discharge slot, which is formed in the shell of the vessel and which in the lower portion of the shell of the substantially cylindrical vessel extends substantially parallel to the longitudinal axis of the vessel.

Abstract: A current-feeding cathode-mounting device comprises a metal-sheathed carrying rail of copper and a permanent cathode plate consisting of the same material as the sheath and joined by welding at least along part of a longitudinal edge and wherein at least an end portion of the rail is unsheathed at least along part of its extent. In order to increase the creep strength and durability and to ensure a low-resistance contact, the carrying rail consists of a hollow copper section, the sheath consists of special steel, the sheath is joined to the carrying rail by a diffusion-preventing non-porous weld, and the permanent cathode of special steel is joined to the sheath by an interrupted seal weld. The carrying rail consists suitably of a copper tube.

Abstract: A method for the continuous pyrometallurgical processing of copper-lead matte having a high lead content relative to copper. In order to ensure an economical and ecologically satisfactory processing, the following steps are performed in a continuous sequence: (a) In one processing stage a suitable atmosphere is provided and temperatures above 1250.degree. C. and a high turbulence are maintained in a molten bath, volatile lead components are incorporated in a fine dust and liquid matte having a decreased lead content and metallic lead included in a copper-containing lead alloy are produced; (b) in another processing stage, gases which contain free oxygen are blown into or onto the liquid matte which has been produced in stage (a) and is at a temperature above 1250.degree. C.

Abstract: The present disclosure is concerned with solvent free or very low solvent coating compositions suitable for use on flexible sheet form substrates particularly textile substrates. The composition comprises a urethane group-containing prepolymer with OH or CONH.sub.2 terminal groups mixed with a urea or melamine formaldehyde resin and a stable aqueous polymer dispersion or solution. The composition may also contain small amounts of an organic solvent. The coating can be applied to the substrate by direct or reverse coating techniques.

Abstract: This invention relates to compositions which are crosslinkable by heating to form polyurethane plastics for coating substrates, preferably textile sheet-form materials, in particular by the reverse coating process. For ecological and economic reasons, the coating compositions are free from organic solvent or contain at most 10% by weight of organic solvent and consist essentially of linear and/or branched urethane prepolymers having blocked terminal NCO-groups, aqueous dispersions of urethane polymers, vinyl polymers and/or diene polymers and/or aqueous polymer solutions and aliphatic and/or cycloaliphatic and/or aromatic amines containing at least two primary and/or secondary amino groups as latent crosslinkers. The chain extending or crosslinking reaction takes place at an elevated temperature in a coating tunnel after the coating has been applied to a substrate.

Abstract: An anode for a cell for electrolytic recovery of nonferrous metals especially copper is provided with a plate-shaped deposition surface, a hanger for suspending the anode in the cell, and a perforated pipe along a bottom edge of the anode for discharging bubbles of gas upwardly in the electrolyte along the faces of the anode. A bar along an edge of the anode can be provided with a feeder for the gas communicating with the pipe and the hanger may have a passage communicating with this feeder.

Abstract: A furnace for the melting and refining of raw copper and/or blister copper comprises a shaft furnace having a lock-chamber feeder for the material at the top of the shaft furnace and an opening into a hearth furnace in which the copper is refined. The shaft furnace and the hearth furnace are constructed unitarily with one another with the shaft furnace surmounting the hearth furnace in such manner that, when the apparatus has been charged, a pile of copper is formed which is supported on the bottom of the hearth furnace and slopes toward a portion of the length of the hearth furnace.
