Title: Home system for altitude and frequency customised one-way logical communications using cylindrical ultrasonic transducers
IPC: G08B1/00
Filed: 1985-09-02
Abstract: Home system for altitude and frequency customised one-way logical communications using cylindrical ultrasonic transducers composed of a piezoxide doublet of simple manufacture or of an electret and of an incremental oscillator. The invention relates to a home system for communications between sensors and alarm stations which can be taken through telephone transmitters. The transmitters and receivers, which can operate on a chosen frequency, are composed of a same transducer comprising an incremental oscillator associated with a cylinder vibrating at ultrasonic frequencies in a horizontal plane. This cylinder, based on a vertical axis 1, can be either a doublet 2 formed of a steel sleeve 3 adhesively bonded to a piezoxide cylinder 4 or an electret. The links, characterised with precision in altitude and frequency, are independent of the azimuth. The number, category, altitude and azimuth can readily be reviewed.

Title: System for heat-shrinking a plastic envelope over a palletised load
IPC: B65B53/02
Filed: 1985-10-11
Abstract: The system comprises two parts connected together via a shaft 1 which provides the articulation. The first, active part is composed of a frame, at the base of which two wheels H are positioned horizontally in order to be able to follow the profile of the pallet, as well as of a boom 1 for shrinking which is positioned equidistant from the two wheels. The second, securing part is composed of a frame oscillating on a shaft 2 enabling the active part to be placed in contact with the palletised load or its withdrawal with the aid of a pneumatic jack F. The system makes it possible, during the heat shrinking, to maintain equidistance from the heat sources as well as the perpendicularity of the thermal impact.

Title: Hydraulic press having rapid opening and closing strokes
Inventor: MICHEL GERARD
IPC: B29C45/67
Filed: 1985-10-30
Abstract: The piston 7 of the thrust cylinders, on the opposite side from its rod 8 connected to the movable plate 2, is integral with an axial extension 11, 12 whose diameter is greater than that of the said rod 8 for a group of thrust cylinders 9, and smaller for another group 10.

Title: Small plastic rope for paraglider hanger
IPC: D07B1/02
Filed: 1988-04-28
Abstract: The invention relates to a small plastic rope used as a hanger in the manufacture of paragliders. It consists of a core 1 made from an artificial aramide fibre called "KEVLAR" in the form of an unbraided strand of more or less 1 square millimetre cross-section; this core is coated by a flexible plastic sheath 2 (made from PVC or other materials) which is coloured. Since the overall cross-section is not greater than 3 square millimetres the sheath is shrunk around the core strand and a round or oval cross-section may be obtained. The plastic sheath forms an integral part of the "small cord" assembly. Main advantage: the smooth structure of the plastic sheath allows an air penetration increase of 30%; this improves the performance of future paragliders.
