Patent FR-2539877-A1 (FR)
Title: Tachometer device for any floating vehicle
IPC: G01P5/02
Filed: 1983-01-25
Abstract: The subject of the invention relates to a type of tachometer for any floating vehicle. It is intended to allow measurement of the speed over the water of any floating craft and consists of a simplified apparatus which nevertheless has high precision, is self-contained and has its own fastening and pick-up system, it being possible to incorporate it either initially, or as a removable accessory, and it is consequently particularly well suited to beach vehicles: sailboards, inflatables, light drifters, etc. It is designed such that all the elements which it comprises may be made of injected plastic thus allowing mass-production.

Title: Device relating to the automatic setting of the alarm unit on a motor vehicle
IPC: B60R25/10
Filed: 1983-10-12
Abstract: Device relating to the automatic setting of the alarm unit on a motor vehicle. The invention relates to a device making it possible to automatically set the alarm unit without risking forgetting and without any supplementary manipulation other than the simple fact of removing the key from the contact. Between the battery 10 and the "starter contact" block 5 there is mounted in series an automatic arming device 7 for an alarm unit 9. This device comprises a movable switch maintained elastically in an active position for feeding the alarm unit, when the contact is broken. When contact is set an electromagnet excited by the supply of current attracts the movable pad and thus disarms the alarm unit. The invention finds an application especially for motor vehicles.

Title: Motor device actuating a system of insulating panels
IPC: E06B9/28
Filed: 1984-03-30
Abstract: According to the invention, the device makes it possible to simultaneously set insulating panels (or other receivers) in motion. A hollow structure member 1, of square or rectangular cross section, receives movable journals 3 and journal-supports 2 located in housings placed on two opposite faces of the said member. These journals and journal-supports provide the link between the internal movement and the external movement, thus activating insulating panels (or other receivers) placed vertically, horizontally or in an oblique position at any angle. Coupling shafts or tie shafts 4 placed inside the member make it possible to firmly attach the support means in pairs. This enables this invention to be original due to a simple, and therefore particularly economical, manufacture. The device according to the invention is particularly intended for producing insulating cybernetic equipment.
