Abstract: Amino acid fractions of different composition are obtained at different times by fractional filtration after neutralization of the hydrolysates. Tyrosine-rich and leucine-rich fractions are specifically treated and lead to the recovery of L-tyrosine, L-cystine, L-leucine and L-phenyl-alanine.

Abstract: The invention relates to a method and a machine for cutting off leads of specific length from electric wire and for processing and equipping the ends of the wire leads. The machine comprises an endless conveyor which bears pairs of close-set clamps and a paying-out station for the wire which pays out the latter tangentially to the conveyor. Cams cause the clamps of each pair to pivot by a quarter revolution in reverse direction from one another. A balance rod forms in the wire situated between two clamps, loops of specific length.

Abstract: A weldable capping film for tear-off closure caps on containers or packages, comprising a combination of a film of low elasticity and a thermoplastic film, and serving to seal the containers or packages hermetically when welded thereto.

Abstract: A threshing machine for peas consisting of a horizontal sieve drum rotatable about a longitudinal axis, containing at least two beater shafts located with their axles parallel to the longitudinal axis of the sieve drum to form several threshing areas, a longitudinal conveyor at the inlet end of the sieve drum for throwing threshed product thereinto characterised in that a prebeater unit comprising a plurality of beater mechanisms extends in a longitudinal direction above the longitudinal conveyor and below a fixed hood, the beater mechanisms having shafts mounted laterally across the width of the longitudinal conveyor and equipped with beater arms staggered with each other in the direction of rotation which beater arms may oscillate freely within their plane rotation.

Abstract: An agglomeration nozzle with an axial passage for the product and an annular duct coaxial with the passage. An annular distribution chamber coaxial with the duct and passage supplies the agglomeration fluid to the duct. A first heating chamber surrounds the distribution chamber and a second heating chamber is disposed below the distribution chamber adjacent the end of the duct. A heating fluid may be introduced into the heating chambers to maintain the distribution chamber and duct at an elevated temperature.

Abstract: A process for the production of flavored vegetables which comprises fermenting a vegetable in the presence of a powdered hydrolysed protein wherein the total amount of salt present in the process is from 1.0% to 4.5% by weight based on the weight of the vegetable.

Abstract: A process for preparing a powdered tea extract wherein black tea leaves are macerated with water, the macerated leaves are extracted first with cold water and then with hot water after which the cold and hot extracts are mixed before being concentrated and dried.

Abstract: The object of the present invention is a modular drier.Each module comprises two fans each supplying a common diffusion chamber (14) disposed between two columns of a group of columns (12, 13). Said chambers (14) adjoin a perforated wall of said columns comprising vertical deflectors, with the opposite wall of these columns, likewise perforated, communicating with a common chamber (15) for exhausting the air used for drying.The invention relates to a modular drier for drying grains, in which gravity draws the grain down in parallel sheets within vertical columns crossed horizontally by the drying air.

Abstract: Movement of a body part or other movable object is measured by attaching a retro-reflecting landmark (8) to the body part. An observation field (4) containing the landmark (8) is scanned using a beam (20) of radiation from a lamp (10) and reflecting it with a rotatable mirror (18) to scan the field. The retro-reflected light (42) is detected and the time of retro-reflection by reference to the phase of rotation of the mirror (18) is measured to provide a signal related to the angular position of the landmark (8) in the field (4). More than one landmark (8) can be observed simultaneously by using landmark (8) with edge filtering characteristics and appropriate arrangements for discriminating retro-reflected light (42) according to spectral characteristics.

Abstract: The cross-sectional area of the airflow duct on at least one face of the fan housing is larger than the cross-sectional area of a cylindrical portion of duct which cooperates with the impeller. A junction portion having an S-shaped cross-section in an axial plane is provided on at least part of the duct periphery between the cylindrical portion and that housing face. The fan duct progressively increases in width from the cylindrical portion to the housing face and the S-shaped junction portion has a point of inflection substantially at the midpoint of its axial length. A reduction in noise level is thus achieved during operation of the fan.

Abstract: A container comprising an outer container and an inner container suspended therein by flexible suspension means.

Abstract: The electric motor with radial air gap comprises a rotor, a stator having a magnetic circuit and windings which form winding heads projecting with respect to the magnetic circuit at the axial ends thereof, a case whose end wall extends radially and a sensor for detecting the position of the rotor fixed on an electrically insulating disc separating that end wall from the winding heads situated on the same side as this wall, applied and immobilized against the case. The sensor has terminals connected to connecting wires which issue from the case at a point remote from the connection point thereof with the terminals, and the internal face of the disc has guide means for leading the wires from one point to the other while passing at a distance from the rotor and the winding heads, which come very close to the end wall.
