Abstract: A projectile to be fired from a tubular or rail-shaped launcher has a warhead integral with a rearwardly extending tube of smaller diameter which contains a propulsive charge inserted between the warhead and a sabot carrying a frangible inertial mass. The rear end of the tube has a constricted opening which, upon detonation of the charge, retains the rearwardly moving sabot while giving passage to the disintegrating mass as the projectile is propelled forwardly. The propulsion gases evolving within the tube are temporarily retained by one or more heat-destructible plugs in the sabot and/or in the tube which melt, burn or char to allow the delayed escape of the gases whereby an in-flight thrust is imparted to the projectile.

Abstract: There is described a spin stabilized projectile assembly including a projectile, a sabot, and a guide ring. The projectile is provided with a shoulder at the rear end of which abuts the sabot, the projectile and sabot being connected by the guide ring which extends around the projectile and part of the sabot. The guide ring is arranged so that after the projectile assembly has been fired and has left the barrel of the weapon the sabot and the projectile separate. The sabot has a diameter substantially equal to that of the projectile; the guide ring is secured to the sabot against relative movement in a longitudinal direction but is rotatable with respect to the sabot.

Abstract: This invention relates to a process for the automatic representative taking of samples of fermented beverages. The method consists in taking samples at several different points in height of the fermentation tank, cooling them and proceeding with a determination of the cells in suspension, measuring the hydrogen potential, the dissolved oxygen, the temperature, and the conductivity, carrying out a chromatographic analysis of the volatile and other matters in accordance with a sequence which depends on the state of advance of the fermentation, and is carried out by an automatic device. The installation is characterized by the fact that it comprises a principal conduit having a water inlet at its end and to which there are connected various sampling conduits, it continues into the exchanger of a refrigerating group and is connected to a measurement unit which has a fluid wiredrawing device at its end. The invention applies to the fermented liquid fermentation industry.

Abstract: A process is described for converting the .alpha.- and .beta.-acids of hops into the iso-.alpha. acids for use as a bitter flavoring principle ingredient for beers. The .alpha.-acids content of the hops is directly isomerized to the iso-.alpha.-acid, the bitter principle ingredient. The .beta. acids in the hops extract is transformed to the .alpha. acid either after a direct separation step before the .alpha.-acid isomerization or the residual .beta.-acids, after the isomerization, are then transformed and the resultant .alpha.-acid is isomerized. The .beta.-acid transformation results from a radiation activation followed by an oxidation step with a per - acid.The isomerization of the .alpha.-acid to the iso-.alpha.-acid is accomplished by reaction with an alkaline earth metal ethoxide preferably the magnesium ethoxide.

Abstract: Beer fermentation apparatus comprises a main pipe for transporting a water-entrained mixture of wort, yeast and gas to a fermentation tank. A measuring device is mounted in a by-pass circuit of the main pipe for measuring the amount of gas dissolved in the water, the device comprising a vertically disposed measuring chamber having an inlet at its lower end and an outlet at its upper end which are connected to upstream and downstream portions of the main pipe for flowing the mixture through the measuring chamber. The chamber inlet is located a sufficient distance above the lowermost end of the chamber so as to effect formation of a relatively stagnant flow region which is substantially free of gas bubbles in the measuring chamber beneath the level of the inlet during flow of the water-entrained mixture through the measuring chamber.

Abstract: An improved arrangement for more efficiently igniting and thereafter maintaining an optimum burning efficiency of a hollow, solid propellant charge cartridge disposed in a combustion chamber at the rear end of a rocket or other ballistic projectile is described. A support tube is mounted for extension coaxially into the hollow interior of the charge cartridge with a radial clearance therebetween. The rear end of the support tube is carried within the locking member at the rear end of the combustion chamber, so that upon bursting of a rupture disc between the locking member and the rear end of the combustion chamber, both the locking member and the support tube can be propelled axially rearwardly out of the combustion chamber. The advantageous function of the support tube to absorb radial acceleration forces during firing of the rocket, is preserved, while thereafter the deleterious effect of having the support tube remain in place during the ignition of the main propellant charge is obviated.

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: A continuous mashing process for producing wort in the production of beer comprises providing a mash mixture of malt and raw grains; continuously flowing the mash mixture through a mash reactor; and heating the mixture during its flow through the reactor to progressively raise the temperature of the mixture at an almost constant temperature gradient from approximately 30.degree. C at the reactor inlet end to approximately 80.degree. C at the reactor outlet end to thereby form mash. During its flow through the reactor, the mixture is agitated in a controlled manner to effectively prevent overheating thereof and facilitate the extraction and diffusion of the active ingredients in the mixture, and the agitation is carried out so as to prevent back-flow of the mash within the reactor. The mash is then filtered to produce wort.
