Title: Yeast homogenising mixer for beer making industry - reduces brewing time cycle by about three per cent
Inventor: MOLL MANFRED
IPC: B01F7/16
Filed: 1976-10-08
Abstract: An homogenising mixer tank for brewers yeast, comprising a vertical cylindrical tank with convergent, conical base. Within the cylindrical part of the tank, a rotary, screw propeller with >=6 inclined blades is mounted on a central, vertical, drive shaft. The propeller is at a level which corresponds approx. with the horizontal plane at which the cross-section of the tank changes from cylindrical conical. Four vertical flat, deflector blades are fixed, evenly spaced, to the interior of the cylindrical wall of the vessel. Each flat deflector blade pref. has a length equal to three quarters of the depth of the cylindrical part of the tank and a width equal to about one twelfth of the dia. of that part. The deflector blade pref. has a chamfered lower end extending into the conical base part by a distance equal to the width of the deflector blade. If the overall height exceeds 100% to 150% of the dia. of the cylindrical part of the tank, a second screw propeller is fitted mounted above the first on the same drive shaft. Propeller blades are pred. set at about 45 degrees to the horizontal. Used in the mfr. of beer to homogenise yeast in a carrier liq. ready to seed a fermenting vessel. The combination of screw propeller(s) and deflectors eliminate vortex formation and provide enhanced mixing efficiency. Homogenisation therefore uses less power than previously and takes less time.

Title: Transportation vessel for spent nuclear fuel - has heat shield protecting contents from external fire by bulging bimetal plate
IPC: G21F5/10
Filed: 1977-03-04
Abstract: The container comprises a bimetal plate fitted to the external surface of the container. This bimetal plate is composed of two metal plates possessing different coeffts. of thermal expansion; the outer plate has a larger coefft. of expansion than the inner plate and both the plates are firmly connected together at their edges and fixed to the outer face of the container. The surface of the bimetal plate facing inwards towards the container and the external surface of the container itself are finished to a high polish and are in intimate thermally conducting contact. There may also be a further metal plate between the bimetal plate and the outer face of the container; this plate has a high polish on the side facing away from the container. If the container is subjected to an external fire, the outer bimetal plate immediately buckles outwards and creates a void (virtually a vacuum) between it and the inner plate or surface of the container. Since the two surfaces of this void are highly polished, very little radiation of heat across the void takes place and the contents of the container are largely protected from the external heat.
