Abstract:
The present invention relates to a pressing device and to a method of providing a change of pressure between two pressure states: a low pressure state and a high pressure state of at least 4000 bar, in a pressure vessel of a high pressure isostatic pressing device in which a liquid pressure medium is used for generating the pressure. A first pressure changing means is used for changing the pressure from one of two pressure states to an intermediate pressure state, and a second pressure changing means is used for changing the pressure from the intermediate pressure state to the other one of said two pressure states.
Abstract:
The present invention relates to a process and a device for the hydrothermal carbonization of biomass, wherein biomass together with water and at least one catalyst is converted in a pressure vessel by temperature and/or pressure elevation into substances such as coal, oil and/or like substances of related type. In order to improve the hydrothermal carbonization of biomass, in particular with respect to the time period of the conversion process, and also with respect to the type and manner of the process procedure, the present invention proposes that, to a pressure vessel which is constructed essentially as a pipe having at least one controllable inlet orifice and at least one controllable outlet orifice, biomass, water and/or at least one catalyst is fed via the at least one controllable inlet orifice, the temperature and/or pressure conditions in the pressure vessel are controlled in such a manner that the charge material fed to the pressure vessel of biomass, water and catalyst is transported in the pipe, wherein biomass, water and catalyst react with one another and at least one reaction product of the charge material is taken off via the at least one controllable outlet orifice.
Abstract:
Improved treatment apparatus (120, 152) is provided for the treatment (e.g., molding, heating and/or curing) of objects such as parts or part precursors (148, 170) including wireless detection of a temperature parameter related to the objects during treatment thereof. The objects include associated microwire-type sensors (150, 174) which have characteristic re-magnetization responses under the influence of applied, alternating magnetic fields. The apparatus (120, 152) have treatment chambers (122, 153) sized to hold the objects to be treated, with one or more antennas (132, 124, 166) proximal to such objects and operable to generate interrogating alternating magnetic fields and to detect the responses of the sensors (150, 174). The detected temperature parameter information is used by an apparatus controller (146) to maintain desired ambient conditions within the treatment chamber (122, 153).
