Patent FR-2267864-A1 (FR)
Title: Method of moulding concrete parts - uses DC passed through concrete subjected to pressure
IPC: B28B7/46
Filed: 1974-04-18
Abstract: The method enables wet workable mixes to be used with the high strength characteristics of the 'dry mix' process, by extracting excess water from the mix without extracting cement, thus reducing the water-cement ration during the pressing and augmenting concrete strength. This is achieved by passing a direct electric current through the wet concrete during pressing and causing an interstitial movement of mixing water from anode (+) to cathode (-). The process entails the simultaneous application of static pressure (P) and a current with a potential gradient of 5 to 25 volts per cm to the wet concrete.

Title: Floating plastics swimming pool cover - placed in overlapping sections which can be weighted down to seal
IPC: E04H4/10
Filed: 1974-06-20
Abstract: A swimming pool cover placed over the pool when not in use protects the water from pollution, consists of plastic sheeting divided into sections, each section having floats, which can be filled with water, attached to the sides resting on the edge of the pool and a third float on the side which is to be joined to the next section. The two sections are joined together by folding back one float filled with air over the other float also full of air, and then weighting the first float by introducing a certain amount of water, thus obtaining a perfect airtight joint between the two sections. Any rainwater accumulating on the cover surface is removed using a pump located in a pocket in the centre of the cover.

Title: Absorption of oil from contaminated water or ground - using cellulose particles modified with organic isocyanates, fatty acids or derivs.
Inventor: HOLST ARNO DR
IPC: C09K3/32
Filed: 1974-11-22
Abstract: Oil is absorbed from contaminated water or water-surfaces or from contaminated ground by use of fine particle cellulose materials modified with an organic isocyanate, high -molecular fatty acid, ester or complex with basic Cr chloride or melamine resin pre-condensate contg. high-molecular fatty acid gps. all of which contain >=14C. The cellulose is readily available from waste products e.g. wood, flour, used paper, cellulose film etc. The materials agglomerate after absorption of oil, making them easy to collect from water or land. The cellulose is biologically degradable and promotes degradation of the absorbed oil in inaccessible places. Contaminated water can be run through a container holding the powder, to remove the oil.

Title: Proximity detector using electro:optical system - transmits light beam into observation field and detects radiation returned from field
Inventor: BELLISSANT ALAIN
IPC: G01S17/10
Filed: 1975-10-31
Abstract: The proximity detector described detects the prescence of an object in a observation field and in a distance range of known extent. An electro-optic transmitter produces light radiation in the onservation field and an opto-electronic receiver detects the radiation coming from the field and produces a useful signal by treating the signal detected. A selective filter circuit (5), set on a predetermined frequency receives the signal detected (S1) and provides an output signal which is passed to the transmitting device (1) via a power amplifier (7). A closed loop is thus formed when the object (A) is present in the field (PR); at this point the loop oscillates at the predetermined frequency. The electro-optic transducer (1) comprises a light-emitting diode (10) and the optoelectronic transducer (2) comprises a photodiode (20) which is connected to a low-noise pre-amplifier (23) followed by an amplifier circuit (25) before reaching the filter circuit.
