摘要： The invention relates to a process for the production of grade AA methanol by distilling raw methanol in several distillation stages, thereby separating grade AA methanol, tail gas, and fusel oil. The methanol produced in commercial-scale synthesis plants does not correspond to grade AA. Therefore, the product must be treated in an additional distillation stage in order to reduce the methanol losses due to fusel oil. The aim of the invention can be achieved by distilling said fusel oil in an additional distillation stage at a return ratio of 5:1 or higher.

摘要： The invention relates to a method for producing unsaturated hydrocarbons. According to said method, in a first step, a hydrocarbon, especially a mixture which contains alkanes, essentially no water, and can contain water vapour, is continuously guided through a first catalyst bed provided with standard dehydration conditions. Liquid water, water vapour and a gas containing oxygen are then added to the reaction mixture obtained in the first step and, in a second step, the reaction mixture obtained is then continuously guided through another catalyst bed for oxidising hydrogen and for further dehydrating hydrocarbons. The first catalyst bed can be heated and the heating in the first step is then preferably regulated in such a way that an essentially isothermic operating mode is created.

摘要： The chemical military materials include both the group of chemical agents used in chemical weapons and the group of fuels used in military aircraft. Chemical military materials must be disposed of at the end of their storage life. A continuous process is disclosed for that purpose. The chemical military materials are first suspended and/or dissolved in water and an alkaline catalyst is added to the aqueous mixture. A reaction mixture is thus obtained. The reaction mixture is brought to the reaction pressure by liquid feeding means, for example a high pressure pump. The reaction pressure lies between 100 bars and 1000 bars. The reaction mixture is heated up to a reaction temperature lower than the critical temperature of pure water. The usual reaction temperature is 350 DEG C. The reaction mixture heated up to the reaction temperature then flows over a catalyst bed that contains a catalytic zirconium dioxide. The catalysed reactions produce a hot mixture of converted materials that is substantially free of chemical military materials. The hot mixture of converted materials is cooled down and expanded in a separator, producing a gaseous phase with CO2, CH4 and H2, an oily phase and an aqueous phase with dissolved salts that may all be dumped.

摘要： A pulsed power supply having a filter output and a battery backup includes electronic apparatus to sense when the AC source is failing. When the pulsed supply output has the same pulses as that which would be produced by the battery, the supply switches to battery backup mode. As the AC source returns, the supply switches to AC supply mode when the AC is at a level where the pulses produced by the supply would be the same as are actually being produced by the battery backup.

摘要： A system (e.g., a power supply) is presented which allows a user to electrically couple a common ground electrical potential of a circuit (e.g., a power supply circuit return) to, or electrically isolate the common ground electrical potential from, an earth grounded chassis, without having to open the chassis. The system may include a metal bolt and nut, wherein the nut is coupled to an electrically conductive bracket. The bracket is mounted upon a printed circuit board and electrically coupled to the common ground electrical potential. When an insulating bushing is installed in a hole in the chassis adjacent to the bracket, and a threaded shaft of the bolt extends through aligned holes in the insulating bushing, an insulating member positioned between the bracket and the chassis, and the bracket, and the threaded shaft engages the nut, the bolt holds the insulating bushing in place, and the bracket is electrically isolated from the chassis. When the insulating bushing is replaced with a conductive washer, the bolt and the conductive washer form a conductive electrical path between the bracket and the chassis. Components of the described system may be employed in systems having multiple cabinets (or complex cabinet systems) to achieve a single point of grounding. System components may also be employed to selectively isolate or couple a power supply return to a chassis ground in devices other than power supplies.

摘要： A current sharing modular power system including, in each module, an inverter circuit and means to determine the current to a common load from the module. A difference circuit is provided to determine the difference between the module supplied current and the average of the current supplied by the other modules. The difference is then utilized to vary the pulse width of the inverter output so that the pulses are wider if the current from the module is smaller than the current supplied by the other modules and the pulses are thinner if the current from the module is larger than the average current supplied by the other modules. The system also includes a voltage sense circuit to adjust the module operation to maintain a constant voltage output.
