A device for energy recovery for a large diesel engine includes a current generator for converting mechanical rotational energy into electric energy. The current generator includes input shaft for applying rotational energy; a steam turbine a first shaft for transmitting the rotational energy of the steam turbine to the input shaft of the current generator a power turbine and a second shaft for transmitting the rotational energy of the power turbine to the input shaft of the current generator, wherein the first shaft and the second shaft are coupled with the input shaft of the current generator. A first coupling device between the current generator and the steam turbine couples the input shaft of the current generator and the first shaft and/or a second coupling device between the current generator and the power turbine couples the input shaft of the current generator and the second shaft are provided.
摘要:
The invention relates to a method for producing regenerated biopolymers in the form of carbohydrates, using a solvent system that contains the biopolymers dissolved therein. The solvent system is based on a melted ionic liquid and optionally a protic solvent or a mixture thereof. The biopolymers dissolved in the solvent system are precipitated in a coagulation medium, said medium comprising a protic coagulant or a mixture of protic coagulants. The method according to the invention is characterized in that the surface tension σ of the coagulant or the mixture of coagulants is 99% to 30% of the surface tension σ of water, the surface tension being measured according to ASTM D 1590-60 at a temperature of 50° C. The method according to the invention is economical and flexible and leads to advantageous products, especially in the form of staple fibers which are especially not fibrillated and have an advantageous wet to dry strength ratio.

The invention relates to a process for removing small amounts of water and possible further constituents from alkali metal amalgam, wherein the alkali metal amalgam is brought into contact with an element which is insoluble in mercury and catalyzes the reaction of water with the alkali metal amalgam and the possible further constituents to form hydroxides and hydrogen.
摘要:
The invention relates to a pipeline system for conveying a salt melt, comprising at least one pipeline (5) through which the salt melt flows, at least one inlet and at least one outlet, wherein the pipeline (5) through which the salt melt flows has at least one gradient inclined with respect to the horizontal and is respectively connected at the lowest positions via a drainage valve (25) to a drainage line (27) and at the highest positions to a venting valve (23). The invention furthermore relates to a method for draining the pipeline system.

摘要:
A silicone rubber composition exhibiting superior adhesive properties with respect to organic resins it comes into contact with during its cure, while at the same time possessing superior mold release properties with respect to metal dies used for its molding, contains: (A) a polyorganosiloxane having at least two silicon-bonded alkenyl groups per molecule; (B) a polyorganosiloxane having at least two silicon-bonded hydrogen atoms per molecule; (C) an alkylene glycol ester of diacrylic acid or an alkylene glycol ester of dimethacrylic acid having the formula (1), wherein R1 is hydrogen or a methyl group, R2 represents an alkylene group, and n has a value of 1-10; and (D) a platinum catalyst.
摘要:
A dry eye treatment device and method of use are disclosed for applying heat to the exterior surface of an eyelid to treat dry eye symptoms which can be caused by meibomian gland dysfunction (MGD). More specifically, a user operable main unit and hand piece are provided that allow the user to heat his/her or another patient's eyelids to a desired temperature, which can effectively and efficiently raise the temperature at the meibomian glands sufficient to melt, loosen, or soften more serious occlusions or obstructions in the meibomian glands, thereby restoring natural secretory function to obstructed glands.
