摘要:
Cleaning compositions which, as powder or as aqueous formulation based on sodium bicarbonate, sodium chloride and/or sugar, comprise a water-soluble polymeric polycarboxylate as dispersant with the exception of those formulations containing only sodium bicarbonate and polyaspartic acids and/or their salts, to the use of these cleaning compositions for the abrasive cleaning of hard surfaces. A method for cleaning surfaces contaminated with deposits using these cleaning compositions.
摘要:
There is described a method and device for simulating a control and/or machine behavior of machine tools or production machines, in which data concerning the machine tools or production machines are transmitted to a simulation device by mans of an intranet and/or by means of an internet. The data can be automatically transmitted to the simulation device, whereby particularly after a change in an item of data from the quantity of data, this item of data is transmitted to the simulation device.

The present invention is a skin care composition which provides a high degree of moisturization without leaving a "tacky" residue on treated skin. The subject composition comprises; (a) from about 2 to about 10 weight percent of a quaternary ammonium compound having the formula: ##STR1## wherein R.sub.1 and R.sub.2 are each alkyl groups having from about 16 to about 22 carbon atoms, R.sub.3 and R.sub.4 are each lower alkyl groups having from about 1 to about 3 carbon atoms, and X is a salt-forming anion, (b) from about 1 to about 40 weight percent of a humectant, and (c) from about 0.01 to about 5 weight percent of non-irritating hydrophobic polymeric microspheres having an average particle size of less than about 50 microns.
摘要:
Water-containing inorganic waste materials, originally in loose form, and which contain water-soluble components capable of reacting with each other are mixed and then compacted at a pressure sufficient to reduce the space, volume between the particles of material, cause the reduced space volume to become filled with water and the reactive components to react.
摘要:
A device for the electrodeionisation of an aqueous electrolyte solution, comprising an electrodeionisation module (1), an ultrafiltration module (21, 22, 1201, 1202, 1203) and a connection piece (3, 10) which connects the electrodeionisation module (1) and the ultrafiltration module (21, 22, 1201, 1202, 1203) such as to be able to guide a diluate produced from said electrolyte solution during operation of said device in said electrodeionisation module (1) from said electrodeionisation module (1) to said ultrafiltration module (21, 22, 1201, 1202, 1203); wherein said connection piece (3, 10) comprises no adjustable pressure-maintaining valve. By means of the pressure drop occurring in the ultrafiltration modules (21, 22, 1201, 1202, 1203) these devices build up a counter pressure behind the electrodeionisation module (1) which is sufficient to ensure the packing density of the ion exchanger in the electrodeionisation module (1).
摘要:
A process for sterilizing a solution comprising hyaluronic acid. The process comprises providing an aqueous solution of hyaluronic acid with a weight average molecular weight from 0.6 MDa to 3.6 MDa, and the concentration of the hyaluronic acid is from 0.04% to 0.8% by weight. The aqueous solution also has an ionic strength equivalent to an aqueous concentration of sodium chloride from 3% to 30% by weight. Once the aqueous, high salt, hyaluronic acid solution is prepared the solution is maintained at a temperature from 40° C. to 80° C. for at least 1 hour and not longer than six days. Following the heat treatment step, the aqueous solution is filtered through a sterilization filter medium to provide a sterilized high salt, hyaluronic acid solution.
