Patent DE-2605456-A1 (DE)
Title: Large leather sheets embossed by rolling action - across narrow dimension of rectangular plate to reduce cycle time
Inventor: DOKOUPIL JIRI DIPL ING
IPC: C14B1/32
Filed: 1976-02-12
Abstract: A method of embossing an ironing leather utilises flat plates; the leather is conveyed with an intermittent motion through the operating region and, while stationary, is pressed against the surface of the embossing or printing plate by means of a moving, rectangular pressure zone. The longer side of this rectangular pressure zone extends perpendicularly to the direction of conveying of the leather, while the direction of its periodic movement is parallel to the conveying direction. By causing the pressure zone to travel across the narrower dimensions of the pressed rectangular, a considerable reduction in the time required for pressing this rectangular is attained. For example, if the area pressed in one operation is 3m x 600 mm, the rolls or other equipment applying the pressure need to travel only 600 mm. as compared to 3 m, in a previous appts. where the rolls moved transversely to the direction of movement of the leather.

Title: Prepn. of acid halide(s) - by carbonylation of halogenated hydrocarbon(s) in the presence of a Friedel Crafts catalyst and a metal carbonyl co-catalyst
Inventor: KORBANKA HELMUT DIPL CHEM DR
IPC: C07C51/58
Filed: 1976-10-23
Abstract: Prepn. of acid halides (I) by reacting a halohydrocarbon with CO in the presence of a Friedel-Crafts catalyst at super-atmospheric pressure and elevated temps. is carried out in the presence of a cocatalyst, which is a carbonyl cpd. of a Gp. VI-VIII metal or a cpd. forming such a carbonyl under the reaction conditions. Amt. cocatalyst is 0.001-5 wt. % (based on the halohydrocarbon). (I) are intermediates with the prepn. of pharmaceuticals, plant protecting agents and dyes. Process avoids the high pressures (50-700 at c.f. 900-1000 at. previously), the high catalyst concns. and unsatisfactory yields of previous processes. This process allows the prodn. of (I) from various halogenated satd. and unsatd. aliphatic and cycloaliphatic cpds. cf. a previous process which could only carbonylate halogenated methane cpds. In an example 23.7 wt. % CCl3 COCl was obtd. from 319g CCl4, 18. 0g anhydrous AlCl3 and 5.0 g Fe(CO)5. CO pressure was 100 atmos. and the temp. was 150 degrees C. 4.m wt. % CCl3COCl was obtd. using no Fe(CO)5.

Title: Aq. flameproofing compsn. for cellulose prods. - esp. paper, contg. aluminium sulphate, dicyandiamide and opt. formaldehyde
Inventor: SEEHOLZER JOSEF DIPL CHEM DR
IPC: C08K5/07
Filed: 1976-11-26
Abstract: An aq. compsn. for flame-proofing cellulosic materials by impregnation contains Al2(SO4)3 and dicyandiamide, and opt. a small amt. of HCHO. Impregnation is of paper. The paper may be for decorative or packing purposes. Cardboard and wood pulp can also be treated. Cellulose fibres and prods. such as paper are not damaged by the compsn. The rate of impregnation is higher than with NH4 salts. Cheap, easily available Al2(SO4)3 can be used, since the hydrolytic effect on cellulose is suppressed by the presence of dicyandiamide. The compsn. esp. contains 90-60 wt.% of Al2(SO4).18H2O and 10-40 (15-25)% of dicyandiamide. The mixt. is used as a 25-20% aq. soln.; this is stable at room temp. If HCHO is added, the molar ratio of HCHO:dicyandiamide is 0.1-0.9:1 (0.25-0.5:1); addn. of HCHO makes it possible to prepare a stable 40% aq. soln.
