Title: Improvements in or relating to the cleaning of cloth
IPC: D06B5/00
Filed: 1961-03-03
Abstract: <PICT:0931462/IV(a)/1> <PICT:0931462/IV(a)/2> <PICT:0931462/IV(a)/3> A process for cleaning cloth prior to bleaching and/or dyeing, comprises impregnating the cloth with caustic alkali solution, winding the impregnated cloth on to a perforated drum rotatable about its longitudinal axis, heating the impregnated cloth by p passing steam into the drum and through the perforations thereof into the cloth, whilst rotating the drum slowly, then washing the caustic alkali from the woundup cloth by passing boiling water into the drum whilst rotating the drum rapidly. The caustic alkali solution may be of a strength of from 1 to 5 DEG B<\>e and it may contain other textile auxiliary agents. In carrying out the process cloth 1 is first passed in loop form through trough 3 (Fig. 1), containing dilute caustic soda solution and after passing through squeeze rollers 4 is wound up on perforated drum 5. After the cloth is wound on drum 5 steam is led through pipe 11 (Fig. 3) into drum 5 and thence through the perforations into the cloth, whilst the drum is rotated at about 15 r.p.m. The lower half of the drum is surrounded by a trough 12 to collect the condensate. After this a cover is placed over the top half of the drum and boiling water is led into the drum through pipe 11 whilst the drum is rotated at between 50 and 300 r.p.m. depending on the thickness of material on the drum. The cloth may be finally rinsed by passing in loop form through a washing trough. The perforated drum (Fig. 2) comprises a perforated hollow shaft 6 and an outer perforated drum jacket on which the cloth is wound. The perforations of the jacket may be covered at the ends, e.g. by a rubber sleeve for a short distance beneath the edge of the cloth. The shaft 6 has a journal 7 with a central inlet at one end and a journal 8 with means for rotating the drum at the other end.

Title: Improvements relating to the phosphate-coating of metals
IPC: C23C22/20
Filed: 1962-02-02
Abstract: A microcrystalline phosphate coating, e.g. of weight between 0.8 and 1.6 g./m.2, is formed on a metal surface, e.g. of iron or zinc or an alloy thereof, by treatment with an aqueous acidic zinc phosphate solution, such as of Zn(H2PO4)2, containing from 0.02 to 1 g/l of aluminium ions as a refining agent for the coating. The aluminium ions may be introduced into the solution as aluminium hydroxide, to form Al(H2PO4)3, or a soluble aluminium salt such as the acetate, sulphate, phosphate, carbonate or fluoborate. The ratio of Al:Zn ions preferably lies between 1:7 and 1:40. Oxidizing agents may be added to the solution, e.g. H2O2, nitrates such as Zn(NO3)2 and NaNO3, chlorates, or organic nitro-derivatives. An example gives a steel plate immersed in the above solution at 80 DEG C. for 7 minutes, after a conventional degrease, and prior to water rinsing and rinsing in chromic acid solution.

Title: Method of machine knitting of a clothing blank
IPC: D04B1/24
Filed: 1977-03-09
Abstract: The knitting operation is started on all outer portions (11-15) of the garment blank (10), for example a back portion (11), two sleeve portions (12, 13) and two portions forming front-part halves (14, 15), at the end of the garment remote from the neck and having a fixed margin (16). These outer portions (11-15) are produced simultaneously until the arm-onset height (18) of the garment (10) is reached. The subsequent narrowing shoulder portion (19) is knitted in one piece by means of continuous stitch rows by the progressive shaping of the outer portion regions into one another according to a desired form of the transitions between these regions (19/1-19/5). The collar portion (24/1-24/3) is then knitted on in a one-part or multi-part manner. The garment blank is thus produced, in the desired final form of its portions, by means of stitch wales extending in the longitudinal direction. The capacity of the knitting machine is utilised as efficiently as possible. The completion of the garment requires only minor finishing work and no seams in the shoulder portion (19) which can be provided with a continuous patterning.
