    摘要: A tube furnace for the cracking of organic feed stock, e.g. naphtha to ethylene, comprises a chamber traversed by at least one conduit system for the organic feed stock. The conduit system in the region of the inlet comprises a plurality of pipes which are united at an intermediate location and communicate jointly with a single pipe forming the discharge portion of the duct system. Preferably the flow cross section of the duct system increases from the inlet to the outlet end. Burners are provided in the wall of the chamber.

    摘要: A method of treatment of substances containing cocoa butter, particularly chocolates, which is suitable for coating machines, wherein the material containing cocoa butter is first heated slightly above the highest melting point of cocoa butter, then subjected to a two stage cooling step whereby the material in first cooled to a range approximately 30* to 31* C. by a cooling medium having a temperature only slightly lower than this range and secondly cooling the mass to 28* to 29* C. by a cooling medium having a temperature only slightly lower than this range, and then heating the material to 33* to 34* C. and subjecting to further processing (i.e. coating). The material after this treatment is in a thermostable condition, has a substantially constant viscosity and may be stored indefinitely under stirring and when maintaining the temperature of the temperature of the material.

    摘要: A method and device of treatment of cocoa butter-containing masses, particularly molten chocolates, destined for subsequent processing, particularly in coating machines, the method comprising the steps of mildly cooling the mass from a first temperature of approximately 45.degree. to 50.degree. C. which is above the highest melting point of the mass to a second temperature at which pre-crystallization in the mass is initiated, sensing the occurrence of heat-producing processes in the mass during the cooling thereof, terminating the cooling upon the occurrence of such heat-producing processes, and thereafter mildly heating the mass, without overheating, to a third temperature of approximately 33.degree. to 34.degree. C., at which the mass is ready for said subsequent processing. The second temperature is thus automatically adjusted to the lowest possible value, which is desirable for the processing properties of the mass.
