Title: Leather affinity testing for leather dyes - using ground leather paste for colorimetry and spectral photometry
IPC: D06P3/32
Filed: 1974-06-07
Abstract: In a dye analytical process to determine the affinity of leather dyes to grades of leather, the latter matl is ground and converted into a homogeneous fibres paste. Its dry residue is adjusted to 10g/1 and its pH-value is set to over 7 (7.3) by adding borax/formic acid. After dyeing at pH-values of 7, 5.5 and 4, the filtrate is tested colorimetrically and the dried leather fibre mat is checked by spectral photometry. This testing procedure requires only 1-10% of the leather, compared with that needed for due tests on leather samples. This method is better reproducible over long periods of time. Time savings of up to 50% have been recorded. No fulling (which is difficult to reproduce) is required.

Title: Vibration free coupling for misaligned shafts - uses interconnected hydraulic cylinders for automatic balancing
Inventor: PELAT PATRICE
IPC: F16D3/80
Filed: 1974-06-28
Abstract: Two parallel plates (3, 4) carried by two shaft ends (1, 2) transmit a torque from one shaft to the other. To overcome possible shaft misalignment a number of double acting hydraulic cylinders (5-8) link the two drive plates. The cylinders are equally spaced along a pitch circle on the plates (3) by fixing all the cylinder trunnions (A) on one plate and all the piston rod clevises (C) on the other. Connecting pipes link all the cylinder chambers on one side of the pistons and a second set of pipes connect the chambers on the other side of the pistons. Shaft misalignment causes the pistons to move in a mutual dependent direction such that the sum of all the distances between the cylinder and piston rod pivots (A, C) remain constant, to prevent vibrations.
