Title: Melting chamber for mfg. cement clinker and similar materials - where min. amt. of combustion gases is used to heat bottom outlet of chamber so good thermal efficiency is obtd.
Inventor: WOTSCHKE JOHANNES
IPC: F27B3/20
Filed: 1978-11-22
Abstract: The parent patent described a process for mfg. molten cement or similar inorganic melts using a melting chamber fitted with a burner. The novelty in the addn. is that the max. value of the heat in the burner flame is controlled to produce a controlled max. temp. in the charge, but only the min. temp. is used at the lower end of the bottom outlet in the chamber through which the melt flows. A suction fan is pref. used for optimum exploitation of the heat in the charge and to maintain the required difference between the pressure (Pi) in the melting chamber and the counter pressure (Pa) in the gas chamber; and heat in the melt leaving the bottom outlet is pref. used for preheating the air of combustion used in the burner. Used esp. in the melting of raw materials, which do not contain any combustible matter, for the mfr. of cement, where good thermal efficiency is achieved.

Title: High-speed stretch-break tow conversion - using positive drive and internal cooling in all tow feed roller assemblies
IPC: D01G1/08
Filed: 1978-12-22
Abstract: Roller assemblies for a stretch-break tow converter consists of >=2 rollers, all of which are made of a material of high thermal conductivity, such as steel, all have internal cooling, and are pressed together at a high loading by hydraulic or similar means. All the rollers are in assembly are positively driven, and >=1 has resilient bearings capable of accommodating minor maladjustments in the roller settings and variations in the tow thickness. At least one of the rollers has a high-friction surface coating of ceramic, sintered carborundum, or similar material. The positive drive to all rollers eliminates frictional heating due to roller slippage, and the heat generated during the breaking process is rapidly removed by the cooling system, hence prodn. speeds can be increased without damage to the two caused by higher temps.
