Inventor: BRISSEAUX ANDRE
IPC: B21D11/07
Filed: 1976-03-23
Abstract: Tubes are bent in alternate directions for the mass prodn. of flat coils with an undulating pattern consisting of a straight section followed by a 180 degrees bend and another straight section; this pattern is repeated to obtain a long, flat coil. The process involves forming a vertical stack of tubes with their axes horizontal in a machine fitted with two rails which are driven outwards. Each rail is fitted with a row of mandrels located on each side of the stack; the number of mandrels corresponds with the number of bends required, plus two mandrels; and each mandrel has a vertical row of grooves matching the number of tubes in the stack. The mandrel rails are driven horizontally to bend the tubes. Each mandrel is fitted on a holder driven along the mandrel rails by a motor, spindle, and a rack and pinion; movements of the mandrel rails and of the mandrel holder are synchronised to obtain a stack of flat coils in one machine cycle. Method allows high speed mass prodn. of long, flat coils contg. a large number of 180 degrees bends.

Patent FR-2310881-A1 (FR)
IPC: D04H1/485
Filed: 1976-05-17
Abstract: A sheet-like textile material, in particular a nonwoven, containing bicomponenent (two-component) fibres, in which one of the components takes up at least a portion of the outer surface of the fibre and has a lower softening point than the other component, is brought into contact with a transfer sheet coated with at least one sublimation-transferable dye. The sandwich-like structure thus obtained, which consists of the sheet-like textile material and the transfer sheet lying thereupon and being further transported together therewith, is exposed in surface areas separated from one another to pressure and heat in such a manner that the dye(s) is or are transferred to the textile material at least in these areas and consolidation of the textile material by fibre interbonding takes place exactly there. Surprisingly, it is also possible to use disperse dyes of low sublimability, which are unsuitable for conventional transfer printing processes. Nevertheless, only extremely short residence times are required for transfer of the dye. Residence times of as short as less than 1 s are completely sufficient.

Patent FR-2360947-A1 (FR)
Title: Studying gaseous diffusion - using an emulsion in a small scale model
Inventor: VADOT LOUIS
IPC: G09B23/12
Filed: 1976-06-22
Abstract: The atmos. is represented by water in a tank. A second liq. representing the gas under investigation is introduced downwards into the water. This second liq. is an emulsion. This emulsion may be either liq. in liq. or gas in liq. The arrangement may be used to study situations either where the gas is lighter than the atmos. or where it is heavier. When a liq. in liq. emulsion is used, the liq. forming the light phase should be non-miscible with that forming the heavy phase. The liq. in which the emulsion is formed may be the same as that representing the atmos. or may be different but miscible with it. Emulsions formed in this way are perfectly adapted to represent the diffusion of gas in the small scale model and may be applied to the problems of diffusion in enclosed spaces such as industrial premises, and to the study of ventilation requirements, as well as the study of emissions from industrial chimneys. The use of an emulsion overcomes problems which arise with the use of saline in water when studying this effect in similar appts.

Patent FR-2339744-A1 (FR)
Title: Silencer for pneumatic cylinders - uses jet pump to reduce back pressure in exhaust chamber with perforated plate leading to ejector and secondary silencer
IPC: F01N1/00
Filed: 1977-01-26
Abstract: The silence is intended for reducing the noise emitted by the air exhausted from pneumatic cylinders. The pipe (1) from the pneumatic cylinder projects inside the exhaust chamber (2). The velocity of the air leaving the pipe (1) entrains air from the chamber (2) and acts as a jet pump in creating a depression in the chamber. The air then flows through the secondary silencer (4). The depression created in the chamber (2) not only reduces the noise but enables the pneumatic cylinder to be exhausted more rapidly. The effectiveness can be further improved by adding a second similar stage. The silencer can also be used with internal combustion engines.
