Title: Gas diffusion into liquids esp. for water treatment - such as aeration of waste waters chlorination etc.
IPC: B01F3/04
Filed: 1975-02-07
Abstract: A gas diffusion device is used for immersion in a liquid in which the gas is to be dissolved. A downpipe carries liquid down from the surface of a reservoir to a considerable depth where gas is diffused into this liquid, residual gas then being sepd. from gas satd-liquid so that this liquid can be reintroduced into the main reservoir at depth without being carried to the surface by residual gas. Used for dissolution of gases in liquid, partic. in water for treatment such as aeration of polluted waste waters, chlorination, ozonising, oxygenation etc. The gas content is maximised at all depths because residual gas no longer rushes treated liquid to the surface. Treatment reservoirs, trout farm tanks etc. can be made deeper and more compact.

Title: Differential biphase binary code decoder - measures time intervals between pulses over preset period to increase maximum data transmission rate
Inventor: HOUDARD JEAN-PIERRE
IPC: H04L7/033
Filed: 1975-10-16
Abstract: Decoding system for signal trains in a differential biphase binary code where it is normally necessary to know the frequency and phase of the clock source signals synchronising the incoming message. The system overcomes the response time problems associated with using a local clock and synchronisation words in the message and to increase the data transmission rate. The decoder uses measurement of time intervals between selected pulses over some preset period, and delivers a local clock pulse in response to each such pulse. A further circuit detects the presence or otherwise of a transition pulse between them, both circuits being based on local clock source synchronised comparators.

IPC: C01G25/00
Filed: 1975-11-28
Abstract: A method is provided for growing highly oriented compound thin films on a substrate by subjecting the substrate to the vapor of a first single element which can react with the surface at a temperature sufficiently high for the reaction to occur which forms a single atomic layer of the first single element on the surface and then subjecting the thus formed surface with a first single element atomic layer thereon to the vapor of a second single element which can react with the first single element at a temperature sufficiently high for the reaction to occur so that a single atomic layer of the second single element is formed on the surface bound to the first single element. This procedure can then be repeated alternately subjecting the surface to the vapors of the first single element then to the second single element, etc. until the compound film reaches a desired thickness. There is further provided an apparatus for carrying out this method comprising a vacuum chamber with evacuating means, a support for supporting a substrate, sources for at least two vapors of two different single elements and operating means for providing on the substrate first a single atomic layer of one of the elements, and then a single atomic layer of the other of the elements.

Title: Multifilament polyamide or polyester yarn - passes round feed roll pair before winding up to control tension
IPC: D01D5/16
Filed: 1977-03-11
Abstract: Textured multifilament yarn of polyamide 5, polyamide 6.6, polyester in the range 22/1 to 167/36 dtex/filament is produced by extruding the individual filaments; cooling the filaments and oiling them; and finally feeding them to a pneumatic false twister which intermingles them together. The individual filaments have dia. of 10-80 mu and are advanced at speeds of 4000-10,000 metres/min. The residual stretch capacity of the filaments is 30-70%. Before being wound up into a package the yarn passes at least once around a pair of feed rolls rotating at a peripheral speed approx. equal to the feed speed of the yarn. Tension in the newly formed yarn is controlled so that it is not stretched and deformed as it is wound up into packages. The device operates at high speeds.

Title: Controlled gain electron multiplier - uses two microchannel plates mounted one on other and having main surfaces held at different electric potentials
Inventor: AUDIER MARCEL
IPC: H01J43/24
Filed: 1977-03-15
Abstract: The electron multiplier has high controlled amplification at low noise levels and is based on a design using microchannel plates, with secondary electron emission. It comprises first and second microchannel plates the second being mounted on the first. The dia. of the second plate's channels is then less than that of the first plate's channels. The electric potentials applied to the main surfaces of the first plate are so calculated that each of the microchannels works in the saturation region of the gain characteristic. The electric potentials applied to the other main surfaces of the second plate are such that the second plate works in the gain characteristic's saturation region as a result of multiplication of the output charge from the first microchannel plate.
