摘要:
Methods and apparatus to improve hot gas filtration to reduce the liquid fuel loss caused by prolonged residence time at high temperatures are described. The improvement can be obtained by reducing the residence time at elevated temperature by reducing the temperature of the pyrolysis vapor, by reducing the volume of the pyrolysis vapor at the elevated temperature, by increasing the volumetric flow rate at constant volume of the pyrolysis vapor, or by doing a combination of these.
摘要:
A waste-heat recovery system for a waste-heat source, made up of an ORC (Organic-Rankine Cycle) postconnected thereto. The waste-heat source is connected with the heating device of the ORC as well as an expansion machine, coupled to a generator, for steam expansion in the ORC, which has magnetic bearings with an associated control device and a power supply via a direct current intermediate circuit of a generator frequency converter. The design and safe operating behavior of a waste-heat recovery system made up of an ORC post-connected to a waste-heat source are optimized. In a power supply failure, the electric energy that a down-running generator continues to generate is used to supply the magnetic bearings with the associated control device in order to ensure a safe operation in the event of a power supply failure.

A hand-operated cooling device for cryotherapy for treating pain, inflammations, muscle tensions or the like, includes a main body and a receptacle, which can be inserted at least partially into the main body, for the exchangeable accommodation and insertion of a gas pressure vessel. The main body includes a gas outlet actuation arrangement, which can effect, by manual actuation, the outflow of a gas from the gas pressure vessel when the receptacle is inserted, and the receptacle includes a cooling surface, which can be cooled by the outflowing gas and by the gas pressure vessel jacket, wherein the gas can be conducted inside the main body and inside the receptacle by a gas conducting arrangement and can exit at the receptacle adjacent to the cooling surface. Commercially available gas pressure vessels, in particular cream dispensing capsules, can be inserted into the cooling device, so that a simple and cost-effective use of therapeutic OT medical cryotherapy having a pleasant cooling effect is made possible.

Disclosed is the use of an aqueous dispersion comprising (a) a micronized sparingly soluble organic benzophenone derivative of formula (1), selected from the crystal modifications (B) and (C), wherein the crystal modification (B) is characterized by a peak in the X-ray diffraction pattern at a d-spacing of about 7.70; and wherein the crystal modification (C) is characterized by a peak in the X-ray diffraction pattern at a d-spacing of about 7.06; and (b) a dispersing agent selected from anionic, non-ionic and amphoteric surfactants; for protecting the human skin from browning and skin aging. The new crystal modification (C) represents a thermodynamically stable compound of formula (1) at 25° C. This modification is therefore suitable in dispersions comprising micro-fine particles.
摘要:
Disclosed is a wind-powered watercraft in which a free-flying kite-type wind-attacked element that is provided with a profiled wing and is used as the exclusive, an auxiliary, or an emergency drive unit is connected to the vessel only via one traction rope, said traction rope optionally fanning out into a number of holding ropes. The wind-attacked element can be modified via at least one active drive element that is disposed thereupon and is effectively connected thereto by modifying the aerodynamic effect thereof in order to be guided into a given position relative to the watercraft or to dynamically maneuver.
