Inventor: LONCHAMP DANIEL
IPC: C10L5/14
Filed: 1985-04-23
Abstract: Process for the manufacture of solid fuels from asphalts and organic matter and the solid fuels obtained by this process. The process consists in grinding a solid asphalt and a solid combustible material at a temperature below 90 DEG C, and then bringing the mixture obtained to a temperature greater than the softening temperature of the asphalt, under pressure, by compressing it, and finally in vaporising a substantial amount of water by returning the pressure to the value of atmospheric pressure. The ability to burn of the fuels obtained proves to be much greater than that of their constituent components taken separately.

Title: Device for holding a load with respect to the single surface on which it is placed, especially on a transport means
Inventor: MAURIN CHRISTIAN-CLAUDE
IPC: B60P7/08
Filed: 1985-07-31
Abstract: Device for holding a load with respect to the single surface on which it is placed, especially on a transport means. The invention consists of a system making it possible to stabilise a load by putting it into abutment against an adaptable, adjustable mobile device resting on the floor without resting against the walls, preventing the movement of merchandise loaded into a road, rail, air or sea transport means. It consists of a set of components of lengths adjustable by sliding, connected into triangles and returning to ground level the bearing points of the horizontal forces which are exerted above the ground, and stop systems allowing lockage in the chosen adjustment positions. This device is particularly intended for immobilising with respect to horizontal surfaces when vertical surfaces are either not present or are too far away to allow wedging with respect to them. This method is particularly intended for fastening on any means of transport, but also at rest for static storage of products not having any inherent stability.

Title: Cathode-ray tube with memory for high-brightness display
Inventor: DREANO JEAN-PIERRE
IPC: H01J29/48
Filed: 1985-12-10
Abstract: The invention relates to a cathode-ray tube with memory for high-brightness display, comprising a vacuum envelope, a memory grid, at least one writing electron gun intended to write on the memory grid, and just in front of the latter a collector grid, at least one spraying electron gun intended to read the electric charges deposited on the memory grid and then to erase them, and electron collimation means. It is notable in that there is a tube for the projection of high-brightness images which delivers an electric power density greater than 2 watts/cm<2>, whose spraying gun provides a uniform current density less than 0.025 A/cm<2> in the exit plane of the spraying gun, with a perveance of the order of 2.10<-6> A/V<3/2>, the electron trajectories, seemingly emanating from a virtual point source, making angles less than substantially 8 DEG with the normal to this plane. It is likewise notable in that the collimation means collimate the electron beam emanating from the spraying gun between an entrance plane and an exit plane, so that the electron trajectories make angles less than substantially 8 DEG in the entrance plane and angles less than substantially 2 DEG in the exit plane with an exit current substantially equal to the entrance current. Application: high-brightness cathode-ray tubes, devices for displaying stationary, semi-stationary or standard television images.

Patent FR-2592713-A1 (FR)
Title: Electrostatic gauge allowing, by means of a single conductor externally fixed onto a non-metallic tank, the level of the contents to be measured
IPC: G01F23/26
Filed: 1986-01-03
Abstract: Electrostatic gauges are currently used for monitoring levels in tanks. When the latter are not metallic, their envelope (the set of walls constituting the tank) may be considered to be a dielectric and, if metal plates with parallel faces are arranged externally on the walls, a planar capacitor is produced with heterogeneous dielectric, whose capacitance varies as a function of the height of the level of the product contained. This technique, the one most generally used, has quite a number of drawbacks linked with the parity of the constituent elements and with its consequences on the electromagnetic radiation (the currents used are of relatively high frequency), the complexity of the wiring and above all, on the residual capacitances whose size may, in certain cases, become so great that it is impossible to employ the method. The object of eliminating the problems mentioned, has led to a device being designed whose essential characteristic is the use of the electrostatic properties of a conductor disposed vertically above the ground. Thus, if a single conductor is fixed vertically onto one of the non-metallic walls of a tank resting on the ground (or on a conducting surface), the distributed capacitance of this conductor varies as a function of the height of the level of the product contained. This formula has the double advantage of reducing the residual capacitance of the gauge, as well as the perturbing electromagnetic radiation.
