Title: Semistatic fresnel focusing device with crossed mirrors
Inventor: PERRIER JEAN
IPC: F24S23/79
Filed: 1982-07-23
Abstract: The invention relates to optical instruments allowing to hold in a fixed position the pseudofocal optical image of a moving radiation source, or vice versa, to obtain orientable emerging beams of parallel rays, from a quasi-punctual light source. It comprises two frames arranged as a reentering dihedron, two Fresnel-steps mirrors with cylindrical parabolic effect and crossed axes, articulations on the steps allowing to make them rotate about axes of fixed direction in each frame, one control for each frame allowing equal rotation motions of the steps, one servo-control for said control by means of a differential thermostat and a reciprocating motor and, according to the case, one energy sensor or one irradiating source. Among the most interesting applications of the invention, it may be mentioned the collection of solar energy by the tracking method, the remote location of moving objects, the optical signalling, the making of test chambers with artificial sun.

Title: Cellular load-bearing building blocks - have ventilation and air intake shafts formed by juxtaposition of blocks
IPC: F24F12/00
Filed: 1982-02-16
Abstract: Four different types of block (1-4) four vertical ducts (5-8) divided into two independent air circuits. Used air enters the system at the top, travels down the inside end duct, rises up the other end duct and makes a high level exit to the outside. This flows heats or cools the two walls of the interior duct which is the fresh air intake, reducing losses to the ventilated building. The bottom block (2) has at least six stiffening ribs (9) that increase the bearing surface and prevent the block from shearing.

Title: Simultaneous prodn. of ceramic prods. and fuel gas - using clay and coal, heat treating using fuel from the coal and collecting prods. continuously
Inventor: HOHMANN HANS
IPC: B28B11/24
Filed: 1982-04-06
Abstract: Method for simultaneous mfr. of coarse ceramic prods. such as bricks, and fuel gas, in a gas tight, indirectly heated appts. comprises submitting moulded articles, dried to 2-3% moisture content, made from a clay contg. 10-60% dry wt. of combustible components such as coal, to a heat treatment at up to 200 deg.C (drying) 200-900 deg. C for firing with hydrothermal solidi cation commencing with simultaneous removal of the fuel components at 700-900 deg.C by introducing a gasifier such as water into the appts.. Both the hydrothermal solidification and the gasification of the fuel constituents are commanded by the quantity of gasifiers introduced per unit of time. The steam from the drying and the fuel gas from the appts. are evacuated continuously until commencement of cooling. A prescribed pressure of at least 100 Pa is maintained in the appts.. The fuel produced is conveyed directly to the heater to provide the temp. of the appts., being burner in an indirect heater. Surplus fuel is carried to other plant. The process is completed after cooling to 150-50 deg.C when the ceramic products are removed from the appts. The process avoids the need for supplementary gas generating plant, production of ash, fly ash, cinders and slags as in prior art.

Title: Control system for autonomous transportation carriages - uses microprocessor to calculate position from beacons reflecting acoustic signals from on-board emitter
Inventor: GUIGNARD CLAUDE
IPC: G05D1/02
Filed: 1982-04-30
Abstract: A microprocessor (80) with dynamic (82) and passive memories is coupled through an interface (88) to an acoustic emitter (90). The emitter output is pulsed and the microprocessor receives signals from a fixed beacon (92) through two detectors (94,96). The microprocessor calculates the difference between the arrival times of signals at the two detectors. Filters (98) ensure only the signals from the emitter are received. The microprocessor also receives signals from angular coders (50,52) on the drive wheel and steering mechanism. By integrating the distance signals the position of the vehicle in a given area is calculated. The calculated and stored values are compared and control signals are issued to the drive motor (44) and steering control to correct the difference.
