Title: Overheating protection appts. for traction motors - uses integrating capacitor to give voltage proportional to current to ensure motor is not overheated
Inventor: MATHIEU ROGER
IPC: H02H6/00
Filed: 1982-05-12
Abstract: The protection circuit is used to aid operators of traction motors in the operation of the motor above its continuous rating, giving a visual indication of ranges of current drawn by the motor and using a capacitive circuit to provide integration of current with time to automatically reduce current to the motor if it has been operated for too long at short term rating current levels. The circuit measures voltage over a shunt and uses transistor inverter to provide electrical isolation between the current shunt and the electronic circuit. The voltage delivered is proportional to current and is applied both to a parallel array of transistor driven LEDs and to an integrating capacitor working into a comparator circuit, containing a zener diode, which excites a relay to reduce motor current when the capacitor voltage is excessive.

Title: Method of producing a metallic structure with submicronic dimensions
Inventor: TUNG PHAM NGU
IPC: H01L21/285
Filed: 1983-03-18
Abstract: The invention relates to the production of a metallic spatial structure, at least one dimension of which is less than a micron. The structure has a base 10, less than a micron in width, and of small height (< 1 mu ). To reduce its electrical resistance, this base 10 is surmounted by a thick metallic layer 11 several microns (3 to 5) in width. According to the method, an opening 9 of submicronic width in a first thin mask 2 is filled with metal: the metallisation is continued until a thick metallic layer 11 is obtained on the free surface of the first mask 2. A second mask 12 delimits the portion to be preserved in the thick metallic layer 11: the latter is "cut away" by chemical or physical attack. During removal of the two masks 2, 12, the portion of the first mask 2 between the metallic layer 11 and the support 1 of the structure can be preserved as a foundation. Two pillars 16 at the ends of the structure stabilise it. Application to the production of submicronic Schottky gates for microwave frequency field-effect transistors.

Title: Cladding panel made in precast reinforced concrete, with dynamic parietal insulation
IPC: E04B1/76
Filed: 1984-01-30
Abstract: Dynamic parietal device of a precast reinforced concrete panel, allowing fresh air drawn in from the outside to be preheated before it is supplied to the rooms of a building. The precast panel consists of two boards made of insulating material which are spaced apart by studs thus creating internally a cavity or air gap. The assembly is sandwiched between two reinforced concrete slabs. An orifice on each face of the panel allows the internal cavity to communicate with the outside. The device is built in such a way as to ensure continuity of the insulating material, but not necessarily of the created cavity, when two panels are assembled together. Moreover, the walls of the insulating material in contact with the internal cavity may be lined with aluminium foil. The invention may be used by people working in the construction industry in order to improve the thermal performance of buildings.
