Title: Device for separating sheets
Inventor: BOURG CHRISTIAN P
IPC: B65H3/48
Filed: 1991-02-22
Abstract: In order to eject individual sheets from a stack of sheets received in a compartment, use is made of a pair of ejector rollers for engaging the adjacent surface of the upper sheet in the stack. These rollers perform a movement of ejection of this sheet towards a common conveyor. A stream of air is blown towards the edge of the sheets with a view to facilitating their separation. Simultaneously, the zone of the rear edge of the upper sheet in the stack is sucked in order to raise it from the stack and thus give rise to effective detachment of the sheet.

Patent FR-2691731-A1 (FR)
Title: System for checking seal between edges of bitumen roofing material layers - uses microwave radiation to heat overlapping edges to expel moisture and fuse surfaces
Inventor: EMMANUEL HOUSSIN
IPC: E04D13/00
Filed: 1992-06-02
Abstract: The procedure consists of subjecting the overlapping edges of the roofing material to a high-frequency radiation at a controlled power so that the edges are reheated locally in the overlap zones, eliminating any water which is trapped between them and improving the adhesion. The edge (8) of the underlying layer of roofing material incorporates an inner metal reinforcement (13) which forms a Faraday cage and acts as a screen for the radiation. The screen can be in the form of a fine metal mesh, while the radiation is delivered from a box (11) which is moved along and parallel to the overlapping edges. In a variant the screen can be situated beneath the lower layer of the roofing material instead of being incorporated in it. The high-frequency radiation is preferably at microwave level, delivered from a series of separate heads (14). ADVANTAGE - Improved seal between overlapping edges of adjacent roofing material layers.
Patent FR-2692397-A1 (FR)
Title: Active sound controller limiting noise transmitted to neighbours - has narrow band filters to enable calculation of effective sound level allowing for building acoustics for comparison with reference level
Inventor: CLAUDE AZAIS
IPC: G10K11/178
Filed: 1992-06-10
Abstract: The sound controller includes one or several microphones (1,2) and a linear amplifier (3) which provide a signal representative of the ambient sound to the narrow band filters (4). The effective sound level is calculated as a weighted sum of the components, making allowances for the attenuation at boundaries with the neighbours. This sum is compared (6) with a reference voltage. When the sound level nears excess, a waving light (7) comes on. When the reference level is exceeded successive attenuation (8,9,10,11) is introduced into the stereo channels of a single amplifier or several channels of different amplifiers. A counter may record the number of excesses and after a certain number may stop (12) the sound for a certain time. USE/ADVANTAGE - For use in public and private buildings. No deterioration in music quality.
