Title: Modular wall panel
Inventor: BARBE PIERRE
IPC: E04B1/14
Filed: 1985-10-14
Abstract: The invention relates to a modular wall panel intended to form the external wall of a dwelling place, especially adapted to the prefabricated constructions for hot countries. According to the present invention, the modular wall panel 8 intended to form, by assembling, the external wall 3 of a dwelling place 1 is made up of two external boards 9 and 10 which are separated by spacers 11 provided with fastening means, at least one of the said boards 9 or 10 having, at its upper part, one or more cut-outs 12 intended for the subsequent filling of the panel with a packing material 13. This method of production makes it possible to lower the cost price, particularly due to the fact that the panel is formed on site using a local product obtained near the building site as packing materials 13. The invention will find its application especially in the field of the construction of prefabricated dwelling places in African countries.

Title: Detector of the presence, in proximity to a checking station, of a responder associated with a carrier
Inventor: BEAUCORPS JEAN-HENRY DE
IPC: G08B13/24
Filed: 1986-04-28
Abstract: The checking station comprises a pilot 18 and an output stage 10, 11, 12 with a radiating inductor 10. The responder comprises an inductor 30 forming an aerial and tuned by the capacitor 31 to the frequency of the pilot. The diode 32 rectifies the voltage induced in the inductor 30 and charges a filtering capacitor 33b. The charge voltage of the capacitor 33b starts a clock 35, which causes the contents of a shift register 36, in biphase code, to circulate cyclically. The contents of the register 36 drives the modulator 34, 34a which damps the resonant circuit 30, 31. The secondary signal thus emitted by the inductor 30 interferes with the primary signal radiated by the inductor 10. This interference is detected by the diode 13, and the signal detected is demodulated by the circuit 21 and composed by the circuit 23 to the contents of the memory 22. The matching detected by the circuit 23 triggers an action, such as the opening of a door, via the output 25.

Patent FR-2603872-A1 (FR)
IPC: A61M5/00
Filed: 1987-06-22
Abstract: A prehensile container is provided for demounting and storing used hypodermic needles and/or surgical blades pending their ultimate disposal. The same hand that holds the container can actuate the closure blade by finger force to clear an orifice for passage of a used hypodermic needle. When the end of the syringe to which the needle is affixed abuts the mouthpiece of the orifice, the finger force can be released to hold the needle between the edge of an aperture of the shutter blade and an edge of the orifice, so that the needle can be separated by withdrawal of the syringe with one hand while holding the container with the other. Another exertion of finger force will let the used needle drop into the container and a second release will restore the closed condition of the container. Internal baffles obstruct the exit of stored needles, to prevent an unauthorized person from extracting a needle from the container by opening the access orifice.
