Title: Microwave isolator with surface wave propagation - has two parallel plates of gyromagnetic material polarised by permanent magnet in contact with conducting plates
Inventor: FORTERRE GERARD
IPC: H01P1/36
Filed: 1981-06-05
Abstract: Two parallel plates (2,3) of a gyromagnetic material are mounted against each other with their side faces (2a,3a) glued to two conducting plates (5,6) mounted parallel to them. The conducting plates are made of soft iron and their side faces fixed to the parallel plates are ground and covered with a layer of silver. The conducting plates form side faces of a rectangular box (10) protecting the isolator. The two side plates are screwed (12) together and the box is closed by upper (15) and lower (16) plates each with a U-shaped longitudinal section. Two absorbent loads (18,19) are applied against each other and are mounted on the parallel plates. A copper conductor (22) is placed between the parallel plates and the loads and is connected to input and output connectors. A polarising magnet (30) is mounted in the base.

Title: Re-supply controller for IC engine with low speed fuel cut-off - uses electronic circuit monitoring engine conditions to determine volume of fuel to be injected in re-supply
Inventor: GOUX JACQUES
IPC: F02D41/12
Filed: 1981-08-11
Abstract: The re-supply is controlled by an electronic unit (1) which measures the duration of the deceleration period and various engine parameters to determine the correct amount of fuel to be injected in order to avoid stalling of the engine. Transducers record the leration (2) of the engine and the engine speed (3). The engine speed is compared (4) against a set speed (w1) higher than the low speed (WR) where the fuel is cut-off and activates the controller. The control circuit uses a down counter (9) driven by a clock (14) with the count pre-set by the engine transducers. When the engine is in the correct speed band the counter output is used to control a solenoid valve in the fuel supply line. A thermal contact ensures that the countdown is inhibited when the engine is cold.
Patent FR-2512118-A1 (FR)
Title: Wind collector and accelerator for wind turbine - uses flat cylindrical structure with open edges and tapered internal ducts to gather and accelerate air onto vertical axis turbine
IPC: F03D3/04
Filed: 1981-09-02
Abstract: The appts. is formed as a low, large diameter cylinder with open edges facing the wind and tapered ducts formed by vertical partitions between the two circular end plates. A vertical axis wind turbine (6) is mounted co-axially with the accelerator structure so that its blades face the flow of accelerated air. The accelerator is formed between two horizontally mounted circular planes (2). Vertical partitions are placed between the two circular planes and curve so as to divert the air flow onto the cupped blades (6) of the wind turbine. The peripheral partitions (7) can be deflected by the wind forces so that these facing the wind are opened to lie parallel to the air flow. A spring arrangement restores them to their normal radial rest position when not facing the wind.

Title: Differential manometer giving electrical output indication - includes sealed bellows arranged to operate three microswitches sequentially when ambient pressure falls
Inventor: FAVIER PIERRE
IPC: H01H35/32
Filed: 1982-03-17
Abstract: The differential manometer includes a flexible sealed capsule (1) in the form of a bellows filled with gas at the nominal pressure of the surroundings. The capsule is supported between the two arms of an elastic U-shaped frame (5). This converts the linear movement of the bellows surface into an amplified rotating movement. Contacts (7A-C) on an extension of one arm of the 'U' are arranged to cooperate with mocro-switches (10,11A,B,C) fastened together in a block. If the pressure surrounding the bellows is reduced, then the bellows itself expands slightly, and the movement is transmitted to operation of the microswitches. The switches may be set to change at different pressures, to give a series of pressure change indications.

Title: High speed rotary mixing mill for e.g. cement and clay flakes - made dust free by rotary valve inlet and screw conveyor discharge
Inventor: BERNAT DANIEL
IPC: B01F15/02
Filed: 1982-03-18
Abstract: A machine for continuously milling and mixing dry or slightly damp powders, e.g. cement with flakes of clay. The machine is of the type comprising a milling and mixing chamber which is gravity fed with materials from a storage hopper via an inlet orifice. The chamber also has a discharge mechanism which delivers the mixt. via an outlet orifice. During the milling and mixing operation there is no open passage between the mixing chamber and the surrounding atmos. via either the inlet or the outlet orifice. The inlet orifice is sealed with a rotary valve between mixing chamber and hopper. The outlet orifice is accessible from the mixing chamber only via a tubular casing contg. a discharge conveyor screw. The milling and mixing mechanism pref. comprises two contra-rotating coaxial cages with overlapped, axially extending bars at different pitch circle dias. Materials require high speed rotation of milling and mixing rotors which tends to spread dust into the atmos. with rotary valve inlet and screw conveyor outlet, the process is dust-free.

Patent FR-2507914-A1 (FR)
Inventor: PRIEFER NORBERT
IPC: B01D46/00
Filed: 1982-06-22
Abstract: In a filter unit for hot dust-laden crude gases, a plurality of filter chambers (4) are attached on the crude gas side to a collective crude gas line (1) and to an unpressurised dust collection vessel (5). On the clean gas side, they open out into a clean gas manifold (14) and can individually be impinged from a backflow line (23) each for cleaning their filter bodies (7). In order to be able to filter hot crude gases directly at a superatmospheric pressure of, for example, 2 to 3 bar, an effective cleaning of the filter bodies (7) is necessary. For this purpose it is proposed to connect the filter chambers (4) in an unpressurised state on the crude gas side for cleaning and to use the pressurised clean gas itself, or ambient air pressurised by the crude gas, for backflushing.
