Title: Independent and automatic alarm system applicable to all electrically-controlled accesses and especially to revolving shutters.
IPC: G08B13/18
Filed: 1984-08-06
Abstract: The invention relates to an audible and/or light or other alarm system, which is allowed to be excited only when a manual manoeuvre (intrusion) is attempted by opening the protected access. The system is linked by isolation circuits 19 and 21 respectively to the terminals 17 and 18 of the end-of-travel switch on closing and to the terminals 14 and 15 of the opening winding of the control motor. The operations of starting and of cutting off the system are carried out automatically by signals derived, after shaping, from signals normally supplied by the electrical control system at the terminals 14 and 15 and 17 and 18 by exercising the closing and opening switches for the access. In this way, the system avoids mishandling and consequently false alarms.

Patent FR-2591644-A1 (FR)
Title: House with maximum insolation
IPC: E04B1/74
Filed: 1986-08-11
Abstract: The subject of the present invention is a type of house whose shape and orientation are designed to collect passively the maximum of solar energy and also possibly actively, as can be seen in Figure 3. In houses of conventional shape, it is known that a maximum of two sides out of four, that is to say 50% of the sides, are exposed to sun. It is also known that in this case, these sides receive the sun's rays at an angle. In fact, in order for the rays to hit a wall full face, only this wall may be exposed, which corresponds to 25% of all the external walls of the house. Consequently, the rectangular or square shape hitherto given to houses is not the most suitable for passively collecting solar energy.
