Patent FR-2124330-A1 (FR)
IPC: B03D1/16
Filed: 1972-02-01
Abstract: In the purification of liquids by flotation, a mixture of gas and liquid is subjected to sufficient pressure for the gas to dissolve in the liquid and form a solution of the gas and the liquid. The solution of gas and liquid without any substantial change in pressure is introduced at a low velocity to the body of polluted liquid in a flotation tank. Initially no gas bubbles are formed. As the solution rises slowly in the tank and it is subjected to a gradually lower pressure, gas bubbles are formed in a gentle manner. Due to the slow rate at which this takes place the gas bubbles will be very small. Since a great quantity of gas is dissolved in the liquid, a large quantity of gas bubbles will be formed. All of these factors contribute to an effective purification of polluted liquids by flotation.

Title: Impressing of skins in vacuo - to modify relief, appearance or the grain
IPC: D06P3/32
Filed: 1973-09-21
Abstract: Impressing process is applied to skins for modifying the relief, the appearance of the grain. EAch skin is treated to the usual preparatory processes of tanning, buffing to equalise the thickness, dressing and, possibly, dyeing; it is then placed, with the flesh side down, on the heating plate of a vacuum drying appts. The impress to be reproduced is placed between the hair side of the skin and the cushion of the airlight cover; the latter is closed and the skin subjected to a drying operation in vacuo according to the usual parameters except that the duration is extended. During the course of the operation, the impress is deeply reproduced on the skin; this has a lasting effet because the constitutive fibres of the skin are ruptured locally by the heat and the suction. The remarkable strength of the grain thus obtd. enables such impressions to be made on thin, pliable skins without the need for costly fixation processes or chemical treatments. The skins after-treatment can be subjected to a wet process and dyed to obtain a two-tone effect that could not be obtd. hitherto. The depressions can be given a lighter shade than the genral tint.
