Patent FR-2308196-A1 (FR)
Title: Two-dimensional image storage device - has conductive grid on insulating ilm deposited on semiconductor substrate surface
Inventor: BERGER JEAN-LUC
IPC: H01J29/45
Filed: 1975-04-18
Abstract: The image tore has a n-doped semiconductor substrate (1), whose one surface is coated by an insulating film (2), the other surface of the substrate being intended for the reception of the image to be stored. The insulating film carries a grid (5) of converted material, limiting a mosaic of discrete zones on the film surface forming the storage element. The latter consists of a semiconductor-insulator system underneath each grid recesses. The discrete zones and the surrounding zones have different boundary surface characteristics, the inversion threshold value of the discrete zones being smaller than that of the surrounding zones. On electron beam scanning the impinged surface is brought to a negative potential, bringing the boundary surfaces into an inversion state for minority charge carrier storage.

Title: Induction heated capillary brazing process - for joining constructional elements for buildings
IPC: B23K1/002
Filed: 1975-07-04
Abstract: The joints are heated by induction. A controlled temp. increase is obtd. and the temp. is maintained during brazing. The deoxidising flux is also retained in the region until the last minute irrespective of the thickness of the parts. Beams, posts and stiffeners can be assembled by this process using joints such as brackets, braces and sleeves. Local overheating is avoided and the flux is not dispersed until the last minute, thus preventing oxidation of the surfaces being brazed.

Title: Asymmetric non-magnetic parts magnetic sorting system - uses alternating magnetic field which directs parts to different conveyors
Inventor: ZOMMER J A
IPC: B07C5/344
Filed: 1977-01-12
Abstract: Asymmetric, nonmagnetic, electrically-conducting parts are sorted according to the position of th asymmetry, by being fed into an alternating magnetic field (AMF) with an induction vector which is at 90 deg. to the asymmetric plane of the part. The AMF generates electrodynamic forces due to the asymmetry of the part, and the AMF has the same density of both sides of the part, so each part is drawn towards one of two magnetic poles according to the asymmetry. Round discs (7) made of two different metals pass along a conveyor and the discs (7) are asymmetric due to the different conductivities of the metals. Vibrators (9) drive the discs (7) along the inlet track (6), and along an outlet track (8) with two paths separated by a partition. The discs are aligned by passing between the poles of a 'C' shaped electromagnet (5).

Title: Error compensation in sync. detector - utilises prod. of sync. signal and switching signal to control channel connections
Inventor: CLAUDET JEAN-PAUL BONNEFOY
IPC: G01R23/16
Filed: 1977-02-03
Abstract: A synchronous detector senses the presence of a frequency component in a noisy signal. Errors in the detector, are compensated for by multiplying a sync. signal by a switching signal. The resultant signal then controls connection of the required signal to a particular channel. A source (4) supplies a signal (Ve) for detection while another source (8) supplies a switching signal (Vc) on a channel (30) controlling a gate (32). This gate can invert the sync. signal while product of sync. (Vo) and switching signals is obtained on channel (36) which controls a gate (1) in detection signal circuit. This gate provides two channel (A', B') output which is applied to two input gate circuit (2) routing the channels onto capacitors (C1, C2) where error signals are developed for the output (Vs).

Title: Aerator for treating liquids - comprises turbo-agitator connected to air compressor giving air injection at turbine level, maximising efficiency with min. air consumption
IPC: C02F3/20
Filed: 1977-05-18
Abstract: A device for aerating liquids, partic. aq., comprises a turbo-agitator and a compressor. The compressor is connected to the turbo-agitator so that air is injected into the liq. at the level of the turbine. The device can operate intermittently, the time being a function of the characteristics of the turbo-agitator, the rate of air and the vol. to be aerated, or it can operate continuously. Problems associated with existing appts. in which the air is introduced through a perforated plate, are avoided. These include large air consumption, lack of adaptability to vessels of different kinds and the risk of blockages. The appts. ensures intimate mixing of air and liq., giving optimum aeration with min. consumption of air. It can be adapted to any vessel and there is no risk of blocking with solids.

Title: Abrasive corundum grains for grinding tools - are prepd. by moulding, pref. between pair of pressure rolls contg. mating mould cavities
IPC: C09K3/14
Filed: 1977-06-10
Abstract: Mfr. of abrasive grains contg. corundum is claimed, e.g. corundum-contg. zircon. The material, e.g. bauxite or corundum-contg. zircon, is melted or milled and then fed onto at least one mould contg. recesses corresp. with the shape and size of the grains or part of the grains. Molten material, e.g. mixed oxides, or ceramics, can be poured onto the mould while in a viscous state; or a powder contg. ceramic and organic binders, e.g. feldspar clay and dextrin lye can be fed onto the mould, heat may be employed during or after moulding. The pref. plant includes two pressure rolls contg. mating recesses matching the size of the grains required; the pref. recesses are polyhedra or multisided pyramids. Either molten material or fine powder can be used; in either case the amt. of milling or melting operations required is reduced, e.g. fine materials can be moulded into grains of suitable size; previously, such fine material had to be remelted. The cost of mfg. large grains, e.g. for grinding wheels, is therefore reduced.

Title: Fluid level indicator for vehicle hydraulic system - has manual control with locking element for actuating member for use during circuit testing
IPC: G01F23/60
Filed: 1977-07-08
Abstract: The fluid level indicator is for a hydraulic system in a vehicle. It has an electrical switch, actuated by a float, and located in a housing. The switch has stationary and movable contacts, which are closed to complete an electrical circuit. This operates a visual indicator, when the level in a container for hydraulic fluid is below a pre-determined point. A manually actuated unit has an actuating member to close the contact for circuit testing. A locking element locks the actuating member (7) relative to the housing (4) in two positions. In a test position, the contacts are closed. In an at-rest position, the moveable contact (5) is at a distance to the stationary one (6).
Patent FR-2359246-A1 (FR)
IPC: B60P3/30
Filed: 1977-07-21
Abstract: In a salt-distributing device (9) located on a vehicle (1), the distributing salt is supplied to a rotating distributing plate (10) by an endless conveyor from a salt container (4). By means of a salt-moistening arrangement, the salt to be distributed can optionally be moistened with CaCl2 lye. For the travelling-speed-dependent proportioning of the salt quantity and of the CaCl2 lye, there is provided a hydraulic conveying-speed control device (15, 20) which is driven by the tachometer drive, which is picked off on the vehicle gear (25), and which regulates the speeds of the hydraulic motor (11) driving the endless conveyor and of the pump (35) of the salt-moistening arrangement. In order, for reasons of cost saving, to be able also to distribute only dry distributing salt, the salt-moistening arrangement can be switched off by means of an electromagnetic switching member. In order that, during distribution of distributing salt moistened with CaCl2 lye, a constant thawing-agent quantity per unit area is achieved, a variable gear (22), which can be switched over electrically together with the switching on of the switching member from a higher starting speed to a lower starting speed, is arranged between the tachometer drive (24) and the conveying-speed control device (15, 20). With the switching on of the salt-moistening device, the salt quantity conveyed is forcibly reduced by the quantity of the CaCl2 lye added.
