Abstract: Process for preparing urea in which,
 in a synthesis zone, at a pressure of 125-350 bar and at the temperature belonging thereto, a urea synthesis solution containing carbamate and free ammonia is formed from carbon dioxide and an excess of ammonia,
 in a first decomposition step, at synthesis pressure or lower, a part of the carbamate is decomposed by supply of heat and the gas phase obtained in this process is condensed in a first condensition zone,
 in a second decomposition step, at a pressure of 4-40 bar, a further part of the carbamate still present is decomposed by supply of heat and the gas phase formed is separated off,
 in a further step, the remaining carbamate is removed in the form of a gas mixture containing ammonia and carbon dioxide, and this gas mixture is processed to form a solution of ammonia and carbon dioxide in water,
 and the remaining urea-containing solution is processed to form a concentrated urea solution. 
<??>The urea solution to be concentrated is introduced into the tubes of a shell and tube heat exchanger, the gas mixture from the second decomposition step is led into the shell side of heat exchanger at the end opposite the place where the urea solution to be concentrated is fed, the solution of ammonia and carbon dioxide in water is fed to the said shell side at a place located between the inlet for the gas mixture and the inlet for the urea solution to be concentrated, and the condensate is discharged from the shell side at the end where the urea solution is led into the tubes.

Title: Process and apparatus for feeding a filter device
Inventor: GRIES WILLI
IPC: B01D25/00
Filed: 1985-07-15
Granted: 1988-11-17
Abstract: A filter press (10) is supplied with material to be filtered by a filling pump (20) and a high pressure pump (26). Both pumps are connected in parallel and designed as eccentric worm pumps. The charging pressure is gradually raised to a final pressure without any temporary dropping so as to reduce the charging time to a minimum. In correspondence with the gradually decreasing absorption capacity of the filter press (10) first the normal speed of the filling pump (20) is lowered to a predetermined lower operating speed at unvarying speed of the high pressure pump (26). If required, then also the speed of the high pressure pump (26) is reduced. If the absorption capacity of the filter press (10) again increases, first the speed of the high pressure pump (26) is raised again to its former value and, if necessary, subsequently the speed of the filling pump (20) is increased again. A control means (52) including a microprocessor unit serves to vary the speed of the pumps (20 or 26) by way of speed control means (36,38). The inputs into the control means (52) are electrical signals corresponding to scanned "values" of the charging pressure. Guide and control magnitudes can be entered freely into the microprocessor unit in response to the properties of the filtering apparatus and the material to be filtered.

Abstract: A gel-like emulsion is prepared by adding an oil to a surfactant continuous phase formed of a monoalkyl phosphate salt, polyhydric alcohol and water. The gel-like emulsion is scarcely dependent on temperature, and a fine and uniform O/W emulsion prepared from the gel-like emulsion reveals excellent stability at the time of production and at storage. The gel-like emulsion contains only a small amount of alkyl phosphate surface active agent of low irritativeness, so that it is usable for cosmetics, pharmaceuticals, industrial products and the like, which are required to have low irritation and high safety.

Abstract: The sampling device for chemical, in particular biochemical process technics, consists of a sterilizable container in which a magnetic stirring system is accommodated whose agitator beam may be adjusted in height also in operation. Fluid flows through a tangential inlet near the bottom to be discharged through an outlet provided in the upper end wall. Beneath the filter membrane there is an extremely small dead space through which the filtrate gets to the filtrate outlet. The lower end of the agitator arm is designed as a pointed flow break-away edge which, in case of rotation, generates an alternating pressure field migrating over the membrane. The device is particularly characterized by short response times and by a long service life due to the fact that without a substantial shearing, the filter membrane is kept free from deposits.

Abstract: A plastics pipe or pipe coupling is made by injection moulding the plastics pipe or coupling body 1, injection moulding at least one sealing ring 3 separately but susbstantially simultaneously, and bringing the body and sealing ring together directly after the moulding while these components are still in a hot as-moulded state, so that a direct thermal bond is formed between them. Preferably, the respective moulds are opened but the components are not stripped but are brought together for bonding while still in position on respective mould members 15, 19. This eliminates intermediate handling and ensures that the moulded components remain clean and of accurate shape and dimension as they are brought together. Moulding apparatus comprises respective injection moulding cavities for the body and sealing ring, and a reversible support for carrying the sealing ring out of its mould and into contact with the moulded body.

Abstract: The invention relates to a method for the manufacturing of a wind barrier or breather web (7), especially in connection with the manufacturing and mounting of construction elements, as well as a method for the manufacturing of a special web in which such a wind barrier is included. The invention is to the fact that a filt web (7a) is joined with a plastics layer (7b) which in connection with its application to the filt (7a) provides zones allowing for the diffusion of moisture through an otherwise waterand windproof finished web product (7). Possibly, there may be used a crude plastics material which is mechanically foamed or comprises an additive which under the influence of heat creates vapour blisters or gas pockets which provide thin fields and together with the embossing function of the filt and/or the press rollers onto the plastics layer form the diffusion zones. The novel wind barrier or breather web has a small mass and thus provides a final product which is very little fire incentive. The wind barrier web is also applicable for further treatment in the form of a special web, a so-called integrated ground beam membrane which replaces the use of separate mineral wool strip,impregnated foundation wall felt and breather paper in connection with a beam arrangement on concrete foundation.
