Abstract: A digital electronic controller for an engine equipped with an oxygen detor located along the exhaust path of the gases and a carburettor equipped with electrovalves for regulating the fuel flow rate.This controller comprises digital circuits for closed loop and open loop regulation including a digital memory in which the carburettor regulation value is permanently stored, a logic circuit for controlling the operating modes and a plurality of amplifiers for controlling the electrovalves of the carburettor.This controller makes it possible to reduce the pollution level of motor vehicles.

Abstract: An alkali salt composition free from hydroxides, melting at a temperature in the region of or greater than 180.degree., and usable in its molten state as a negative electrolyte for accumulators comprising an alkali metal negative electrode and an alkali alumina separator, contains an alkali metal amide, at least one alkali halide and an alkali hydride. It may also contain aluminium amide.

Abstract: The primary winding of an ignition coil is placed in series with the collor of a switching transistor. In order to protect the transistor against overvoltages, the collector is also connected to a level comparator and the base receives a two-state control signal which is synchronous with the rotation of the engine. One input of the comparator is connected through a divider network to the collector of the transistor and the outer input is connected to a fixed direct-current voltage source. Provision is also made for an error amplifier connected to the output of the comparator, and for a summing circuit which is connected to the control input of the transistor and receives the control signal.

Abstract: The invention relates to a process of treating squeezing juice having a high protein and sugar content, obtained by squeezing vegetable matter to be used as foodstuff. This process comprises the following steps:submitting said squeezing juice issuing from a squeezing press to a first inoculation with a first mesophile homofermentative lactic bacteria in a proportion of at least 10.sup.4 bacteria per milliliter;maintaining the thus inoculated juice at a temperature comprised between 28.degree. and 35.degree. C., preferably 30.degree. C., during 15 to 20 hours, under slow agitation and without aeration, so as to obtain a suspension constituted by an insoluble fraction of vegetable and microbial proteins, and a residual liquid phase, said suspension having a pH comprised between 4.2 and 4.5;separating said soluble fraction from said liquid fraction; andseparately treating the residual liquid and said insoluble fraction.

Abstract: An alkali salt composition free from hydroxides, melting at a temperature in the region of or greater than 180.degree., and usable in its molten state as a negative electrolyte for accumulators comprising an alkali metal negative electrode and an alkali alumina separator, contains an alkali metal amide, at least one alkali halide and an alkali hydride. It may also contain aluminium amide.

Abstract: The device is adapted to be used in a manual or motorized lifting system comprises a self-tightening jaw-block which normally lets a lifting or an auxiliary cable pass through it, whereby a releasing device, by an excessive speed of the cable relatively to the jaw-block, lets jaws clamp the cable and an interrupter stop the motors.

Abstract: A pack comprising a plurality of superposed layers of unit loads and at least one strap encircling said plurality of superposed layers. The bottom layer of the pack has formed therein at least one elongated free space or channel extending in a direction parallel to the axis of the loop of said at least one strap and capable of accommodating the arms of the fork of a lift truck. The strap or straps have a low tension, but when the arms of the lift truck fork are upwardly engaged into the free spaces, the straps are tightened and firmly hold the load which can therefore be handled safely. The straps slacken when the pack is deposited on top of another pack, thereby allowing the upper pack to chocke itself onto the lower pack and thereby allowing to form columns of stacked packs with a greater number of packs and a higher degree of safety than with hitherto known packs.

Abstract: In a vehicle guidance system, a circular-section guidance rail is embraced y a detector on a vehicle. At a fork, where the rail progressively broadens prior to dividing, the rail height is reduced so that a detector, when tilted to select one branch of the fork, has its lowered side between the rail and a side wall of a channel in which the rail is mounted and its raised side riding over the broadened rail.

Abstract: Production of fermented liquids such as beer is continuously carried out under sterile conditions by flash sterilizing a mixture of wort and bitter substances by direct steam injection, boiling the mixture to complete transformation of bitter substances incorporated in the wort, decanting a precipitate formed in the wort under aeration of the wort by sterile air or oxygen, fermenting the wort by bringing the wort under sterile conditions into contact with yeast immobilized on an inert support, storing the fermented wort in the presence of yeast under sterile conditions and passing the fermented wort under sterile conditions into contact with a protease fixed on a support.

Abstract: Wort suitable for making e.g. beer is produced by extracting ground chit malt with a mixture of hot water and malt, the proportion of malt being 10 to 40% by weight on a solids basis of the dry weight of the mixture of ground chit malt and malt.

Abstract: A steering system for a guided vehicle comprises a coupling device for coing the steering axle actuating linkage both to a detector for guiding the vehicle along a guidance reference member and to a steering gear, the coupling device comprising first and second elements respectively mechanically linked to the steering gear and the detector and mounted for movement along first and second guide bars, each element being movable between first and second positions on its guide bar, the guide bars being so coupled to the actuating linkage that an element in the first position transmits movement to the actuating linkage and in the second position is ineffective to transmit such movement.

Abstract: An improved apparatus for batch treatment of textile materials in the form of broad widths is provided in which an enclosure is provided with a closure means at its ends and having provision interiorally for two perforated hemi-cylindrical plates placed concentrically in the lower and upper parts of said enclosure and said plates being movable according to vertical translation; said enclosure preferably being cylindrical and having a ratio of length to diameter of between about 1 and 10:1.

Abstract: Process for dyeing, by exhaustion, textile fibres of basic character with anionic dyestuffs in a solvent medium in the presence or absence of water wherein the dyebath is a homogeneous ionising liquid medium and the cations of the bath are replaced by H.sup.+ protons in the course of the dyeing, the latter being effected at a temperature equal to or less than 80.degree.C. and apparatus for use of this process which comprises apparatus for dyeing according to the process claimed in claim 1 which comprises a dyeing vessel for dyeing with solvents, a circuit for removing the dyebath continuously or by fractions, means for substituting the cations of the bath with H.sup.+ protons, a recycling circuit ensuring the reintroduction into the vessel of the bath from which all or part of its cations have been removed, means for regulating the flow and means for regulating the temperature.
