Patent FR-2233459-A1 (FR)
Title: Concrete beam building framework - hollow beams are interconnected to allow flow of concrete between them
IPC: E04B1/20
Filed: 1974-06-10
Abstract: Corner and intermediate columns and horizontal beams spanning between these columns form the skeleton for the walls and floor. The columns and beams are hollow and are interconnected, one with another, so that when the concrete is poured into horizontal beams, it flows into vertical columns as well. Thus, when the concrete has set, the framework is monolithic. Prior to pouring concrete, prefabricated wall elements can be put in place, as well as any reinforcement bars. One whole storey is therefore formed in one operation, involving only one set of formwork and one concrete pour. This saves duplication and time wasted stripping and removing each lift of formwork and is therefore quicker and easier than the conventional method.

Patent FR-2306829-A1 (FR)
IPC: B31B27/00
Filed: 1975-04-09
Abstract: Integrated equipment is for producing extrusion blown tubular film and converting the film into specific bags or panels etc. The tubing is produced vertically, pinched and then allowed to fall parallel to the fising bubble. Ancillary equipment for welding, cutting, perforating, printing or other operations treat the web during or at the bottom of its descent. The design utilises the decent path to complete post extrusion blowing operations, instead of simply passing the film down on to intermediate storage spools and requiring to house the post extrusion operations elsewhere. Avoids the use of spools and associated progressive differential speed control devices accepting film produced at constant rates on to spools of changing diameter.

Title: Magnetic sepn. of solid particles - by passing suspension in liq. through inclinable tube, incorporating conveyor band, in magnetic field
IPC: B03C1/02
Filed: 1976-06-25
Abstract: A process for sepg. materials magnetically, by passing a suspension of finely divided solid particles in a liq. vehicle through a tube placed in a magnetic field, incorporates orienting the direction of flow and of the magnetic field so that the deflecting force acting on a magnetisable particles consists of a magnetic force and a component of the force of gravity, while the deflecting force acting on a non-magnetic particle is only a component of the force of gravity. If M and S are the magnetic force and the force of gravity and X is the angle between the direction of flow and that of the force of gravity, the component of S opposing M is S. suix and can be modified by the factor suix while the deflecting force acting on a non-magnetic particle is only the component S.suix. An appts. for carrying out the process incorporates a tube which can be oriented is relation to the direction of gravity and which has a magnetising system extending along its length, a feed hopper and product receives connected flexibly to the tube, and a moving band, constituting one wall of the tube, for transferring deflected particles along the tube. The non-magnetic particles are deflected from the direction of flow, the magnetisable particles are deflected in an opposite direction and the weekly magnetisable particles are not deflected. There is less tendency for the magnetisable particles to adhere to the wall than in existing processes.
