Title: Spindle drive on numerically controlled machine tool - has variable speed motor with power takeoff gear carrying motor shaft
IPC: B23Q5/56
Filed: 1975-02-22
Abstract: The power takeoff gear wheel (2) and the drive gear wheel (4) on the drive spindle are coupled together by a circulating toothed belt (3') which is held in tension by at least one tensioning roller (7, 7a).

IPC: D06B19/00
Filed: 1976-08-20
Abstract: Textile piece goods are process with steam, being fed forward first of all continuously through a heating zone under one condition and then forward continuously at a reduced speed, through a zone in which they dwell for a period and are exposed to the action of an atmos. of steam. For the fixing of dyestuffs on piece good treated with dye liquor or printed, and esp. for treatment of flat or pile woven fabrics, knitteds, tufted piece goods, or non-wovens, the goods are first of all simply prefixed. In this stage they are passed through the atmosphere of steam for less than one third of the total fixing time for the dyestuff used on the particular fibres, in a smooth, open, stretched condition. Following this operation, they are post- or finish-fixed as they are conveyed through the atmos. of steam in a rucked or folded condition. In this process, polyamide tufted carpets are treated for 40 secs. in the stretched condition for prefixing and then are treated for 2-5 mins. in the folded conditio for final fixing. The installation comprises a steam proof housing having a heating zone conncting to the housing inlet, followed by a dwelling zone through which the goods pass more slowly; the heating zone being widened out to give the prefixing action. In this zone the cloth runs in one or more loops. According to the type of fabric, the goods are traversed as hanging or running loops or are fed through over rollers at each turning of the loop. In the dwelling zone the goods pass through on an endless belt or along a series of chutes.
