摘要： A process is disclosed for insolubilizing casein coatings for leather utilizing alkoxy alkyl ureas. The coatings are cured in the presence of an acid catalyst. The casein coatings of the invention avoid the disadvantageous use of aldehydes such as formaldehyde and glutaraldehyde to cure the casein and reduce its water sensitivity and unexpectedly show improved wet abrasion resistance.

摘要： A process and apparatus for charging a capacitor, particularly for flash guns with a fast flash series, so as to achieve a short charging time while avoiding a high charging current pulse, the charging current during the course of the charging being regulated to a value which at least approaches a constant. The time constant of the charging circuit is altered during the charging process by a controlled resistance arrangement which is controlled in dependence upon the charging voltage of the capacitor.

摘要： A process for the preparation of soft and hard resins, and their use in surface-coating binders are disclosed. According to the invention, soft and hard resins are prepared from a urea, formaldehyde and a CH-acidic aldehyde by reacting a urea of the general formula (I) or (II) ##STR1## where R.sup.1 and R.sup.2 are hydrogen or identical or different alkyl, A is alkylene and X is oxygen or sulfur, with formaldehyde and a CH-acidic aldehyde of the general formula (III) ##STR2## where R.sup.3 and R.sup.4 are identical or different alkyl, aryl or alkylaryl wherein the urea, formaldehyde and CH-acidic aldehyde are employed in a mole ratio of from 1:2:2 to 1:4:4, at from 60.degree. to 150.degree. C., in the presence of an acid and in the presence or absence of a solvent and/or diluent, and then treating the product with a base in an anhydrousmedium.

摘要： A coffee or tea pot is placed on a base plate of the coffee/tea maker. A boiler zone which includes a boiler vessel is located laterally adjacent the pot so that the pot is heated from the side when placed on the base plate in a predetermined position, as determined, for example, by locating notches or grooves. The boiler unit is laterally extended to partly surround the circumference of the side walls of the pot with extension wings. The back of the extension wings is insulated, for example by a housing, which also surrounds the boiler. The arrangement permits a short path of boiling water or steam from the boiler to the top of the pot, while efficiently transferring heat thereto.
