Abstract: A cosmetic cover for lining a prosthesis, with a distal section, and with a joint section which, when the cosmetic cover for the prosthesis is fitted in place, covers a joint mechanism arranged between a proximal prosthesis component and a distal prosthesis component, wherein the joint section is made from a 3D spacer knit having an upper textile and a lower textile, which are spaced apart and attached to each other by support threads.

Abstract: The invention relates to a cosmetic cover (1) for lining a prosthesis (10), with a distal section (2), and with a joint section (3) which, when the cosmetic cover (1) for the prosthesis is fitted in place, covers a joint mechanism (30) arranged between a proximal prosthesis component (40) and a distal prosthesis component (20), wherein the joint section (3) is made from a 3D spacer knit having an upper textile and a lower textile, which are spaced apart and attached to each other by support threads.

Abstract: A process for the production of high-quality activated carbons from carbonized, self-regenerating, carbon-containing biomasses selects the carbonized biomasses from HTC carbon from fruit stones and HTC carbon from nut shells. The carbonized biomasses together with potassium hydroxide, sodium hydroxide or a mixture of both hydroxides as activator are subjected to a heat treatment at temperatures at which the activator exists in the form of a melt. The activator and the carbonized biomasses are present in a weight ratio of 0.5:1 to 6:1 at the beginning of the heat treatment.

Abstract: A prosthesis element for lining a prosthesis or for forming a prosthesis component and to a method for producing a prosthesis element from a flat base material, consisting of at least one blank made of a flat base material. The blank is bent, whereby a hollow body is formed, opposing edges being connected to one another in the bent state.

Abstract: A device for converting biomass with a water content of at least 50% to gaseous products includes a reactor filled at least partially with a packing including at least one filler body for accommodating supercritical water and a hydrothermal molten salt. A heater is arranged to heat up the reactor and its content. A first feeding pipe is coupled to the reactor to feed water and salt solution into the reactor. A second feeding pipe is coupled to the reactor to feed to biomass into the reactor. A discharge pipe is coupled to the reactor to discharge gaseous products from the reactor. An outlet is proved in the bottom of the reactor for removing portions of the molten salt.

Abstract: A method for converting biomass having a water content of at least 50% into gaseous products includes providing a reactor containing supercritical water and a salt melt. The salt melt includes at least one of a salt and a salt mixture. The reactor and the salt melt are heated to the reaction temperature. The biomass is heated to a preheat temperature. The biomass heated to the preheat temperature is fed into the salt melt. The biomass is heated to the reaction temperature so as to commence a conversion of the biomass into the gaseous products, so as to release from the biomass at least one additional salt into the salt melt. An amount of the salt melt containing at least a portion of the at least one additional salt is withdrawn from the reactor and the amount of the withdrawn salt melt is replaced with a fresh salt solution. The gaseous products are removed from the reactor.

Abstract: The invention relates to a membrane filter unit for liquid or gaseous media, comprising a bundle of capillary membranes which are open on at least one front surface side and which are cast in an area which is close to the end of the open membrane ends, in a sealing layer forming a hardened head part. The open membrane ends protrude on the outer side of the sealing layer. The sealing layer is arranged on a spacer element which has a layer which is penetrated by the capillary membranes and which is non-permeable in relation to the casting material which hardens in order to form the sealing layer. The invention also relates to a method for the production of a membrane filter unit.
