Title: Automatic cut=out for idling vehicle engine - senses clutch accelerator and gear positions, together with temp. to stop and re-start engine
IPC: F02D17/04
Filed: 1979-09-28
Abstract: The control circuit is mounted in the starter motor power line from the ignition switch (4,10,3,8) and has five separate inputs. These are taken from: a gear selection sensor (20), a clutch sensor (21), an accelerator pedal operation sensor (22), a stop-start input (25) and an engine temperature sensor, e.g. a thermistor, (24). The first three inputs feed an AND gate (25) which also receives an input from a second AND gate (27) fed by the remaining two inputs. Further logic circuitry is supported by a memory (36) and a delay unit (37). Solid state logic may be replaced by three relays and five switches. The temperature sensor activates a relay which allows the system to perform its automatic cut-out function only when the engine is above a predetermined temperature. This ensures that the engine will not be stopped if a restart is too energy consuming, i.e. when the engine is cold.

Title: Refining of molten metal, esp. steel, in oxygen converter - using top blowing through lance, and bottom blowing through tuyeres with small outlet dia.
Inventor: LEROY PIERRE
IPC: C21C5/35
Filed: 1979-12-28
Abstract: In the converter, 75-97% of the total O2 required is blown downwards through an injection lance; whereas the rest (R) of the O2, viz. 3-25%, is blown upwards through vertical or oblique tuyeres located below the surface of the bath. Oxygen (R) is fed as jets with max. dia. 18 mm, esp. max. 12 mm, at the tuyere outlets; and is used at a non-increasing rate of flow. A neutral or oxidising stirring gas may be added to oxygen (R). Oxygen (R) is pref. supplied at a constant or decreasing rate during the entire blowing period; and the stirring gas is pref. added to oxygen (R) at the critical stage of decarburisation of the melt, and then at the end of refining. Oxygen (R) pref. forms 3-10% of the total O2 required. The benefits of top blowing are combined with the advantages of bottom blowing in a flexible process; and the life of the tuyeres is increased.

Patent FR-2476154-A1 (FR)
IPC: D03D47/28
Filed: 1980-02-15
Abstract: The subject of the invention is a method for inserting a weft thread into the shed (21) of a weaving machine, in which the length of a weft thread (4) to be inserted is previously measured and then the measured weft thread is inserted in the form of a loop which has a retained leg and a thrown leg, of which the latter is displaced more quickly than the former, the loop being thrown by clamping between two intermittently rotating discs (for example, 8, 11). According to the invention, during the acceleration of the thrown thread between the exit of the throwing device and the entrance of the shed, the thread is retained and driven forwards in the form of a loop in the plane of the loop, and the loop is tensioned in the zone of connection between the thrown leg and the retained leg.

Title: Suction nozzle for machinery cleaning - is of elastic material adapting to vacuum cleaner pipe with suitable contours
IPC: A47L9/02
Filed: 1980-05-07
Abstract: Rubber which is resistant to oil and has a Shore hardness of 95 is used for a three-part suction nozzle for cleaning machines, esp. delicate and valuable machines. The nozzle consists of a mouthpiece, rectangular in section with well-rounded corners, and which tapers back slightly to blend into a tubular fitting. A curved connecting piece fits into the tubular socket and attaches to the line from an industrial vaccum cleaner. Seen from the narrow side, the bottom lip of the nozzle is cut away and set back by about halft the depth of the nozzle. The elasticity of the nozzle and its shape, the depth of the breadth of which is as 1:6, prevent any scratching or more serious damage during the cleaning operation.
Patent FR-2484862-A1 (FR)
Title: Injector for contacting gas with liq. to form emulsion - injects high speed gas co-current at low angle of incidence
Inventor: BOULENGER PAUL
IPC: B03D1/14
Filed: 1980-06-18
Abstract: The flow passage for liq. is designed so that liq. pressure is reduced as the liq. approaches the gas injection zone. Here, gas is injected at a very high speed, e.g. several hundred metres per second. The injection of gas is cocurrent with the flow of liq. and at an angle of incidence which is very low, pref. below 10 deg., w.r.t. the axis of flow of the liq. The mixt. advances through an expansion zone of the passage to form a fine emulsion. The pressure in the liq. is then raised to a level which remains lower than the pressure at which liq. is admitted to the mixer. Pref. the mixer passage converges in cross-section as it approaches the injection zone. Immediately downstream of the injection zone the passage is non-convergent where a confluence of fluids takes place. The confluence zone is followed by a divergent length of passage leading to a chamber where undissolved gas is recovered and from which it can be recycled. The mixer can be used for a wide range of gas/liq. contacting applications, e.g. oxygenation of waste water, carbonating drinks, introducing chlorine and ozone for disinfection. Also in the pharmaceutical industry for injecting gas into biological reactions. Very short contacting time reduces energy requirements. Minimal wastage of undissolved gas.

Title: Liq. flow rate required to fluidise solid, e.g. in reactor - for catalytic reaction, is reduced, with energy saving, by adding gas stream
Inventor: EUZEN JEAN-PAUL
IPC: B01F33/40
Filed: 1981-07-06
Abstract: In mobilising the solid particles in a solid/liq. mixt., the liq. flow rate required is reduced by adding a gas stream. Having determined the min. flow rate (cu. m/sq. m of section x s) of liq. alone for agitation of the particles, the liq. flow is reduced to 10-90% of this rate, and a gas flow, at a rate 5-80% of that of the liq. in the same units, is added. The gas may or may not be a reactant. Used for mobilising solid reactants or catalysts in aq. solns. or organic liquids, esp. by fluid upflow in a bubbling bed reactor and in treatment (e.g. hydrotreatment) of hydrocarbon liquids. The height of a reactor may be reduced by a factor 0.1-0.9; there is a diminution of about 0.1-0.9 in the capacity of the liq. pumps required, and in the energy consumed; and operating flexibility is increased.
