Patent FR-2337271-A1 (FR)
Title: Transferring hot melt or matte between large vessels - using vacuum pump made of graphite and contg. no moving parts
IPC: F04F3/00
Filed: 1976-12-21
Abstract: Plant for manipulating a molten metallurgical material, consisting of two vessels located side-by-side. In one vessel is a pump contg. an inlet channel through which the melt is drawn upwards into a chamber by applying a vacuum. A valve then cuts off the vacuum and connects the pump chamber to atmos. pressure so the melt flows through a U-shaped outlet channel into the second vessel. The inlet and outlet channels of the pump, and its chamber, are pref. all located in a single block of material made of, or coated with, graphite, the shape of the outlet channel being designed so the melt flows by gravity into the second vessel. The pump pref. uses a timer switching the valve between a vacuum pump and the atmos.; and a sensing electrode is located in the pump chamber to give a signal when a specified level is reached by the melt. The two vessels pref. consist of one container divided by a sill. In use e.g. a molten nickel sulphide matte at 830-850 degrees C, and contg. 22 wt.% S can be pumped at 200-300 kg/hr. from one vessel to another while leaving slag or dross floating in the first vessel. The pump has no moving parts in contact with the melt.
Patent FR-2336119-A1 (FR)

Title: Diffuser for ultra-fine solid and liquid particles - has wool thread coated with particles and pulled before air jet to blow into chamber
IPC: B05B7/14
Filed: 1977-01-20
Abstract: The appts. is used to diffuse ultra fine solid and liquid particles. It comprises a block (1) with a cone-shaped cavity (28), its larger end fitted to a chamber. A glass tube (26) fits into the top (5) of the block and guides a woollen thread (27). This passes across the smaller end (25) of the cavity, pulled by a drive roller (9) and tensioned by an adjustable pressure roller (10, 12, 13, 14). The thread traverses a container (29) holding the ultra fine material which clings to the thread. As this passes through the block, an air jet (4) diffuses it into the chamber, baffle plates trapping the larger particles.
Patent FR-2380431-A1 (FR)
Title: Propulsive charge - incorporates screen between propellant material and bonding to outer envelope, preventing migration of active constituents
Inventor: WAITZENEGGER CLAUDE
IPC: F02K9/36
Filed: 1977-02-15
Abstract: A propulsive charge incorporates a thin flexible screen between the blocks of propellant material constituting the charge and the bonding of the charge to the structure of the outer envelope. The bonding consists of plastic enclosures which have important characteristics for the mechanical and chemical stability during storage. The screen is a material which is impervious to the migration of the active constituents of the propellant material, and which can be applied easily to complex geometrical shapes. Problems associated with modifications of the internal structure of the bonding are avoided. Such modification is generally due to the migration of active components of the powder, e.g. nitroglycerine, causing a loss of efficiency. The invention prevents the migration occuring and provides efficient protection against permature ignition.

Patent FR-2394380-A1 (FR)
Title: Textured pattern on one surface of thermoplastic film - by expanding plasticised material into depressions of embossed foil
IPC: B29C48/10
Filed: 1977-06-14
Abstract: A synthetic film, consisting pref. of thermoplastic material, is heated to its plasticising point and fed through a calender having two smooth surfaced bowls. Simultaneously, pref. metal foil, which has been previously given an embossed patterned surface, is fed through the hot film. The relief pattern is brought into contact with the hot film and the two are highly pressed together. The hot film is thus able to fill the cavities of the relief patterned foil completely, whilst the heat is being dissipated, and the thermoplastic film is given a textured surface. The previously embossed band of material may consist of a film of thermosetting resin which has been given a thin metal layer. In the process, a thermoplastic resin may be melted to a fluid with a uniform viscosity and extruded through a broad slot nozzle as a thermoplastic film in the plasticised condition, and textured directly. The calender has two internally cooled rollers. The one coming into contact with the embossed band is surfaced with rubber, whilst the other cover which the plasticised film moves has a polished metal surface. The process applies the textured pattern to one surface only so that the film can be used for coating purposes more sucessfully. Temp. and pressures used cannot damage the thin pressing plate of Al foil or synthetic material, and the relief is applied by using the heat of the extruded material.
