Abstract: The invention relates to a mould for packaging desserts, particularly for ice-cream cake with coating syrup containing fruit or pieces of fruit. The mould is in the form of a cup comprising an opening through which the dessert is introduced into and removed from the mould and is characterized in that it comprises a first compartment near the opening which defines a first space and which is intended to receive a product solid at the storage temperature and a second compartment which defines a space below the first space and which is intended to receive a syrup liquid at the storage temperature, the second compartment comprising a central part situated at the bottom of the cup and communicating with the first compartment through an opening and a peripheral part which consists of circumferentially spaced grooves or depressions arranged in a star around the central part and which forms a flow channel for the syrup and also acts as a stiffener for the mould.

Abstract: To obtain a pasteurized cheese in powder form which, after reconstitution, has the properties of Mozzarella, a colloidal lactic solution having protein/lactose and protein/calcium ratios at least about twice as high as those of natural milk and a pH of from 5.0 to 5.5 is prepared, the pH of the solution thus prepared is adjusted to between 6.3 and 6.4, the solution is pasteurized and its pH is returned to 5.0 to 5.5 before drying by spray-drying.

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 the soldering industry. The device comprises a frame supporting a crucible for a bath of molten filler metal, the bottom of the crucible being traversed in fluid-tight manner by a sonotrode sliding under the action of a jack fixed to the frame. An ultrasonic energy generator is associated with the sonotrode and controlled heating means are associated with the crucible. The active end of the sonotrode has a recess with at least one impression of a shape complementary with at least a portion of the outer surface of the parts to be soldered. The jack moves said active end alternately in and out of the bath. The invention is particularly useful for the soldering of aluminum tube cross-heads for heat exchangers.

Abstract: A process for collecting volatile aromatics which are entrained with gases evolved during the wetting and extraction of fresh roasted and ground coffee beans and contained in part within the extract itself, and thereafter combining the collected volatile aromatics with processed coffee extract and/or soluble coffee to produce an instant coffee product having improved flavor and aroma is disclosed. The instant coffee product obtained by this process is also disclosed.

Abstract: The present invention relates to a process for bonding together boards of wood with surface rough from sawing or with smooth surface, or sliced off or peeled veneers, wherein at least one of the surfaces to be brought into contact is coated with the aid of an expanding polymer glue containingat least one hardenerand at least one volatile pore-generating agent,the mating surfaces are brought into contact with possible application of a pressure and the whole is then heated up to a temperature at which the expansion of the glue has been provoked, up to a rate of expansion of between 30 and 100%. The invention also relates to the product used for said bonding and to the final material obtained.

Abstract: This releasable screw and nut bearing mechanism comprises an internal central screw, a coaxial external nut constituting a socket made of several segments, the outer diameter of the screw being smaller than the inner diameter of the socket in order to provide a free gap therebetween in which a plurality of angularly spaced planet rolling members are disposed and adapted to mesh both with said screw and with said socket, this assembly being releasable by moving the socket segments radially outwards in order to free the screw from any meshing engagement with the rolling members, at any time, irrespective of the relative angular positions between the screw, the socket and the rolling members. Spring means may be provided for constantly urging the rolling members away from the screw, and cage means are provided for guiding the rolling members both axially and radially.

Abstract: A system for the control of a paper machine headbox having sensors for the measurement of the parameters of the process and actuators of the members of the process, functionally connecting at least most of the sensors to an at least equal number of actuators via a multivariable centralized control member which makes it possible to control each actuator by the taking into account and processing of the measurement information of one or more sensors, and causing the measurement information to act on each of the sensors functionally connected to the actuators on one or more members to obtain a resultant action in which only the parameter measured by this sensor is influenced while the secondary repercussions on the outer parameters are eliminated. Another characteristic, the invention permits rapid intervention taking into account the information on the substance flow rate at the headbox, eliminating the usual disturbing influences due to the hydraulic values of the process.

Abstract: A process for forming a vegetable extract in a system comprising a series of cells containing coffee and coffee substitute, by contacting progressively fresher vegetable materials countercurrently with an extraction liquid which enters an inlet cell and is withdrawn in batches from an outlet cell characterized in that the outlet cell and each succeeding alternate cell contains more coffee than any one of their respective adjacent cells and during or after each draw-off the pair of cells containing the most exhausted vegetable material is disconnected from the system for discharge and reloading, and after each draw-off a pair of cells with fresh loads of coffee and coffee substitute is added to the system so that the outlet cell is the second in series and contains the majority of coffee of the pair, the amount of soluble solids in each draw-off being approximately twice the amount drawn off in a standard process.
