Patent FR-2569808-A1 (FR)
Title: Force-multiplier functional drive device
IPC: F16H21/12
Filed: 1981-03-26
Abstract: Force-multiplier functional drive device, intended for all movable and immovable rotary mechanical plants (electrical energy production in particular). Device intended to replace the device registered on May 22nd 1980 under number 80 11643, due to its "jemmy" force lever system 1 being replaced by a so-called "eccentric" force lever and due to the framework 9 being used for the sliding of the roller 3 in its convex shape instead of its concave shape. It is represented in the appended drawing by an eccentric disc 1 producing its force which is both demultiplying and multiplying on a roller 3 bis connecting the two branches of a knee-joint connecting rod 5. Its fixed pivoting point 2 is in the top part of the circular arc-shaped framework 4, on this same spindle there is also fixed either a drive pulley, or a lever 8 in some way representing a pedal box arm. Since, however, the working force of this eccentric is digressive in step with the distance between its fixed pivot point and its point of action on the roller 3 bis, a knee-joint/connecting rod combination 5 has been provided, the connecting rod for the first half of the travel, the knee-joint for the second part. The spacing of these two branches produces a power which is complementary and progressive until the very end of the travel. Built in the shape of a circular arc 4 it represents two important utilities: the first serving as a guide to the roller 3 fixed on the same shaft as the roller 3 bis, the second by the fact that the travel of this roller 3 almost vertically forces the connecting rod 5 into an oscillating downwards movement on the roller side and upwards on the crankshaft side 7 thus improving the thrust angle of the connecting rod compared to its central spindle. It is finally to be noted that this device which allows a very significant gain in energy, although the circular paths of the drive eccentric and of the receiving crankshaft are identical, may multiply, on a same machine, the first actuating the second by means of its gain in energy, and so on and so forth.

Inventor: TADOKORO TOMOO
IPC: F02B53/04
Filed: 1981-07-16
Abstract: A rotary engine with a housing, to which a rotor housing and two lateral housing parts belong, which latter parts are fixed on surfaces of the rotor housing remote from one another in order to define a working chamber for the rotor. A generally triangular rotor is arranged in the working chamber for the rotor. The intake device includes an intake port, intended for operation at low load, which is formed in one of the lateral housing parts so that it opens into the working chamber for the rotor, and intake ports for operation at medium or high load, which are formed in the other lateral housing part. The intake ports for operation at low or medium load are designed so that they are opened in relation to a working chamber once this chamber has been shut off in relation to an exhaust port and so that they are essentially closed simultaneously. A control valve, which is closed during operation at low and medium load, is assigned to the intake port for operation at high load.

Title: Safety mains socket with protected terminals - has rocking cover plate with sliding action and only accepts simultaneous insertion of plug prongs
Inventor: LAROUDIE CHRISTIAN
IPC: H01R13/453
Filed: 1981-08-04
Abstract: The socket consists of an upper plate (2) with holes (21,22) to accept the prongs (60) of a plug. The cavity of the socket has a platform (3) with aligned holes (31,32) which lead through to the base plate (5) on which the mains terminals (51,52) are situated. A cover slider (4) made of a tough, insulating, material, blocks the passage of the prongs. The slider is of triangular shape with the apex ridge (43) lying midway between the two prong entry bores and in a plane normal to their axes. Its upper side has a central boss (44) which keeps it in position, with a small amount of play, between the cover plate and the internal platform. The slider can slide sideways to uncover the terminals. A spring returns it to the cover position. When the prongs of a plug are inserted, they generate cancelling rocking couples on the slider but their pushing forces combine to move the slider against the action of the spring. If one side of the cover is pushed down by an object (e.g. a screwdriver) inserted in one hole only, the rocking action will cause the opposite arm to join into the other hole (41a) and prevent sliding and hence inadvertent removal of the protective cover slider.

Title: Solar energy traps built flush with and as part of roof - involving sundry plastics or rubber components
Inventor: FILIPPI RICHARD
IPC: F24J2/46
Filed: 1981-11-09
Abstract: Solar energy traps are designed for integrated installation during construction of a roof so that the traps are flush with and part of the roof structure instead of being carried on top. Details of the preferred assembly include use of a dark heat absorbant panel which may be rigid, specifically of blackened aluminium or other stainless metal or alloy, or flexible, specifically of a black grade plastic of e.g. polyethylene or 'rilsan' (RTM-polyamide). The trap has a transparent cover sheet specifically of glass or polycarbonate, opt. is backed by a panel of self-supporting insulation matl. such as rigid polyurethane foam. Less conspicuous and less vulnerable than free standing traps, and reduces the quantities of other roofing matls. needed, e.g. tiles, correspondingly. The example construction refers to use of strip seal profiles or polychloroprene or neoprene.

Title: Control centre for intruder alarm system - uses counter to address sequential gates with inputs from intrusion sensors
IPC: G08B26/00
Filed: 1982-03-05
Abstract: A number of detectors are connected in series to a tristate gate. Other tristate gates receive inputs from a timing control and from photodetectors. A counter sequentially addresses the dates to provide an input signal for a memory. The gate outputs pass through a programmable logic gate then via a programmable timer to a selector circuit. Instructions pe for programming and selection actions are controlled from the counter. A keyboard and control unit permits initialisation of the system and contains a display panel for visual indication of an intrusion. An amplifier in an alarm unit operates a relay to power an audible alarm. An interface permits connection to a telephone line for remote signalling purposes.

Patent FR-2514806-A1 (FR)
Inventor: MATHIS PAUL
IPC: E04F13/02
Filed: 1982-10-15
Abstract: For plastering walls having insulating boards, a first coat of plaster is initially applied to the insulating board and after a period of time in which the first coat of plaster is able to harden, a reinforced coat of plaster is applied. In this process, after the hardening of the first coat of plaster, a reinforcing fabric or the like is initially fixed on the surface of said coat by means of knifing filler, e.g. by means of a thin layer of mortar, and after solidification of the latter thereon, the second coat of plaster can be applied. If necessary, it is also possible to build up a relatively large number of layers in this way. Despite an unstable base, an outer coat of plaster is produced which avoids cracking and is nevertheless stable and which can provide good protection for the building element provided with insulating boards.
