Abstract: A process is disclosed wherein the decaffeination of solutions of caffeine in fatty media is effected with hydrophilic, phenol/formaldehyde polymeric resins having phenolic functional groups. In particular, the solutions are contacted with resin to effect decaffeination and the solvent medium is recovered, whereas the exhausted resin containing adherent caffeine and any non-caffeine solids may be regenerated for re-use. Other features of the invention are described in the specification.

Abstract: A batch process for the sterilization of particulate solid materials, in which a batch of particulate solid material to be sterilized is introduced into a rotary vessel shaped so that rotation of the vessel imparts a tumbling action to the solid material; the solid material is heated in the vessel while rotating the same to subject the material to a tumbling action; a lubricant liquid is injected under pressure into the vessel at a temperature in excess of the temperature of the solids; the lubricant liquid and solid material are held at a sterilization temperature while maintaining the tumbling action; and the sterilized solid material is withdrawn from the vessel under aseptic conditions.

In a realization said means comprise a body from which depend at least two sleeves provided for housing with a tightening fit a portion of the sections to be assembled. The sleeves are preferably removably fixed to the body.

Abstract: This reciprocating piston, particularly for heat engines, compressors, coises at least one upper bead the side surface or periphery whereof presents projecting portions and recessed portions. The projecting portions of this periphery have an initial diameter, before running-in, such that the initial diametrical clearance between the periphery of the upper bead and the cylinder, cold, is substantially equal to half the clearance usually provided between the conventional upper bead and cylinder, so that, during the running-in, the projecting portions of the upper, pressed against the inner wall of the cyliner, may contract and be compressed in the recessed portions which absorb them.Further, the piston presents at least one cavity opening on the periphery of the first bead of the piston and at least one mobile piece partially occupying this cavity and which moves therein due to the movement of the piston, to prevent, without other deterioration, any considerable deposits of calamine.

Abstract: During the recycling operation, the carrier gas is subjected to a pre-purification prior to the conventional purification, the flow rate and the pressure of the carrier gas being maintained at strictly constant values at the inlet of the chromatographic unit. The method is primarily applicable to low-pressure gas chromatography and permits finer separations as well as higher productivity than atmospheric-pressure chromatography.

Abstract: Weapon system, notably of the light anti-tank type for infantry, which is fully consumable, which comprises a launching tube acting as a sealed tactical container and a rocket, preferably of the hollow charge type, and a rocket acceleration propulsion unit provided with a casing consisting of a compound fibre-and-resin assembly, preferably of the aramid-and-epoxy type, said casing consisting of two sections, i.e. an inner sleeve and an external structure.

Abstract: Means for air conditioning a building interior so as to afford optimum comfort to all its occupants in terms of their physical characteristics. An automatic control mechanism monitors devices for measuring humidity, air velocity, bulb temperature, and the weight and body temperature of humans or animals occupying the said interior. The mechanism comprises a calculator assembly comprising a computer and a comparator. Control is effected by comparing in the comparator the ideal temperature calculated by the computer with the actual measured temperature. The transmitted error signal imposes the control either on a heater or on a ventilator 1 in response to a command signal from a thermostat.

Abstract: Apparatus and process for coating frozen portions of a foodstuff with a granulated product with a conveyor carrying plates for supporting the portions and adapted to advance stepwise and sequentially to:depositing the granulated product on the plates,positioning the portions on the plates,supplying heat to the surfaces of the portions,coating the portions with granulated product anddischarging the coated portions from the conveyor.

Abstract: An automatic voltage regulator comprises means for monitoring the voltage of an alternator with a voltage crossover detector and a pulse generator so that a train of output control pulses are produced which are controlled in their mark to space ratio by the output of a circuit which senses the amplitude of the alternator output voltage.

Abstract: A process for eliminating the flatulent sugars present in soya which comprises preparing an aqueous soya suspension containing from 5 to 45% by weight of dry matter, inoculating the suspension thus prepared with at least one strain of Saccharomyces uvarum which has reached the state of growth on a medium containing at least one sugar having at least one .alpha.-D-galactopyranosyl bond and fermenting the suspension under anaerobic conditions for at least 8 hours at a temperature of from 15.degree. to 50.degree. C.

Abstract: A respirator is provided for the treatment, particularly in the home, of persons suffering from respiratory insufficiencies. The respirator comprises a reciprocating linear electric motor compressor having a gas intake orifice connected to atmosphere for example, a compressed gas discharge orifice connected to a respiratory mask, a piston, a spring acting on the piston, and an electromagnet for moving the piston against the action of the spring to supply compressed gas to the mask via the discharge orifice. A thyristor pulse generator is controlled by a clock to provide pulses to the electromagnet to define the insufflation time. The compressor operates only during the insufflation time.
