Patent FR-2280476-A1 (FR)
IPC: C25F7/00
Filed: 1975-06-26
Abstract: A method for forming an arcuate electrode adapted for the electrolytic production of grooves in the arcuate surface of an article, in which grooves are first formed in a plane metal blank. The grooved blank is then reshaped to have a curvature corresponding to that of the article, and the grooved curved surface of the blank is coated with an insulating material. The insulating material is then removed from the surface of the blank, except in those areas overlying the grooves, and the thus bared portion of the blank is then eroded, for example, by etching, so that the residual insulating layer projects from the surface of the blank. In use, the thus formed electrode is employed as a cathode, with the projecting insulation being held in close contact with a corresponding curved surface of the article to be grooved. The article is connected as an anode, and an electrolytic liquid is directed to flow in the channels formed between the electrode and the article.

Title: Metal heat treatment in molten salts - where evaporator is used to recover salts carried over into washing tank
IPC: B01D1/00
Filed: 1975-11-28
Abstract: Heat treatment salts are recovered from water used to wash the workpieces after treatment. The water is fed to an evaporator heated to 200-600 degrees C. by the same salt as that employed in the treatment, so water is removed and the salts are dry enough to be recycled into the heat treatment bath. The pref. evapn. temp. is 200-500 degrees C and the steam evolved is condensed and returned, esp. as hot water, to the washing bath. The pref. plant consists of a boiler for heating the salt and a pump feeding the molten salt to the evaporator. The molten salts are used for the heat-treatment or colouring of iron, steel, tool steel, brass or bronze, and the carry over of salt from the molten salt bath to the aq. washing bath is 20-100 g salts/m2 of workpiece surface. This loss is expensive and also causes environmental contamination if the spent washing soln. is fed into the drains.

Title: Air conditioning system for wood drying - feeds steam into air from dehydrator and condensate from refrigerator is heated by compressor
IPC: F26B21/08
Filed: 1976-04-06
Abstract: The wood drying system employs a boiler supplying steam which is fed into a layer of air blown from an air dehydrator. A part of the water condensed by the evaporator of a refrigeration system is fed towards a heat exchanger which also receives a heat exchange fluid with hot gasses leaving the refrigeration compressor at high pressure. This gives water at a temperature of 80 deg. C with energy obtained from the work obtained from compression, and increase in temperature in the drying chamber is avoided. The water is vapourised in a boiler and the steam is injected by tubes into the layer of air. Humidification can be obtained by injecting fine water sprays into the air blown from the dehydrator. Then, a part of the water condensed at the evaporator is pumped into the spray forming system. The diffusion of water from inside the wood to its surface is carried out at a constant rate.
