Patent FR-2604698-A1 (FR)
Title: Portable electric can opener
Inventor: BINEAU PIERRE
IPC: B67B7/70
Filed: 1986-09-12
Abstract: A casing 8 encloses a drive mechanism 17 to 19, 21, 22 for driving a roller 1. A lever 29 ends in a blade 33 capable of laterally straddling the roller. A handle 42 of the casing and an arm 41 of the lever may be seized together in order to displace the blade 33 and start the operation of the motor 17 by means of a switch 52. The handle and the arm extend in the opposite direction from the roller, relative to the casing. The roller is retractable, against a spring 67 when the lateral wall of a preserve can bears against it, whilst the blade 33, pivoting about the spindle 31 of the lever, is driven into the lid of this can. Use for making handling easier, reducing the force to be exerted for perforation and making the apparatus adaptable to any type of can, possibly a deformed can.

Title: Integrated antenna/mixer device and weapons guidance systems
Inventor: EGON FLETCHER MALCOLM
IPC: H01Q1/24
Filed: 1986-10-01
Abstract: A radar system comprising a dielectric lens (1) for receiving HF arranged so as to focus the radiation received through a substrate (2) on a network of integrated antenna/mixer circuits supported on the rear face of the substrate and an HF generator which applies radiation through a dielectric matching device to the rear face of the substrate so that some of the radiation is applied to the antenna/mixer circuits in order to form the local oscillator signal intended for the circuits while the rest passes through the lens to form the radar output signal. Such a radar system may be fixed on board a guided missile so that it has a field of view which is fixed in relation to the missile, this field of view being moved or subject to scanning by movement of the missile en bloc, for example by rotation of the missile.

Title: Muscle motor
IPC: F03G5/00
Filed: 1986-12-22
Abstract: The present invention, called a muscle motor, relates to a device making it possible to increase, and make more efficient and even, human effort. This muscle motor is characterised by a crank system causing a kinetic flywheel to rotate, which kinetic flywheel actuates gearing which is integral with a transmission shaft which causes the propellor of a craft to rotate, freeing the sailor's arms and allowing him thus to be as at ease as if he were on a boat with a combustion engine.
Patent FR-2611892-A1 (FR)
Title: Method and device for measuring, constructing and plotting real angles in order to find the position of an observer
IPC: G01C1/00
Filed: 1987-02-25
Abstract: In order to plot on a map the position of an observer with respect to 3 significant points (landmarks), according to which the observer uses a device for angular sighting and construction making it possible, using a set of mirrors, to separate rules, pivoting at the same point, by the exact value of the angles formed between the 3 points sited in pairs, these angles to fix in space, and to plot these solid angles directly onto the map, in order to find thereon his/her position at their vertex. This instrument consists of 3 rules 1, 2 and 3 rotating about the hollow pivot 4. The images found in the direction of 3 are reflected towards the eye of the observer by a vertical mirror 8 with a double reflecting face, fixed onto the wheel 7, which rotates through an angle equal to half the angle in question, by virtue of the movement of the toothed wheels 5, 6 and 7, so that the observer can superpose the directly viewed image lined up along 1 with the other reflected image lined up along 3. The rule 2 acts as a reference for the first sighting. The 2 angles are locked and plotted directly onto the map, in order to determine thereon the position situated under the spindle 4. A more precise version with 2 mirrors is provided as a variant. The instrument according to the invention is more particularly intended for navigation and topography (surveying).
