Abstract: Continuous pressure boiling of beer wort is carried out in a multistage column having an upright inner wall enclosing a head region near the top of the column, a sump region near the bottom of the column and a wort compartment between the head and sump regions. The wort compartment includes a plurality of superposed, substantially horizontal plates. Each plate is provided with an overflow weir on its upper surface with an opening between the overflow weir and the wall of the column. Regenerative preheated wort is charged onto an upper plate and flows downward from one plate to another over the overflow weirs and through the openings. A heated gaseous medium introduced into the sump region raises through the openings and heats the downward flowing wort to boiling temperature to degas and free the wort from undesirable foreign substances. Vapors from the wort are condensed in the head region and discharged, and the processed wort is discharged from the sump region.

Abstract: In a bottle- and can-filling machine the bottles after filling are fed from a star wheel directly to a capping carrousel and cans after filling are fed from the star wheel via a feed device along a feed path to a closing machine. This feed device is a feed chain extending from the closing machine right up to the star wheel of the filling machine and lying to the side of the center of the can path at the star wheel. Normally the chain lies to the outside of the center of this path at the star wheel and has fingers engageable behind the cans.

Abstract: A liquid discharge nozzle for container filling valves includes an inner member and an outer member which together define an upstream section of a passage for the flow of the liquid to be filled into a container therethrough in the downward direction. The outer member has a valve seat cooperating with a valve member to open or close the passage. The outer member forms a groove which accommodates the lower part of the inner member to form a siphon-type trap therewith, the groove being separated from a downstream section of the passage, which is situated in the discharge nozzle portion of the outer member, by a ridge. A plurality of openings, such as notches or bores, is provided through the ridge in substantially radial directions, each of the openings extending from the groove to slightly upwardly of the valve seat. The openings have such dimensions that surface tension of the liquid present therein prevents gases from penetrating through such openings into the upstream section of the passage.

Abstract: An arrangement for displacing piece goods has a plurality of supporting shafts and a plurality of grippers mounted on the supporting shafts so that when some of the grippers come into contact with the piece goods at location whereat no gripping openings are provided they do not prevent other of the grippers from unobjectionable engagement into the openings of the piece goods, and the grippers are provided in such a number that they can engage in the openings arranged in accordance with any of the different opening patterns.

Abstract: A double-seat valve unit with leakage control has a greater valve plate located below a smaller valve plate, adjusting bars connected with the valve plates and arranged so that the adjusting bar of the greater valve plate extends through the interior of the adjusting bar of the smaller valve plate and both valve plates move to an open position from above downwardly, a leakage conduit having a portion located inside a valve housing and movable outwardly, an annular gap formed between the adjusting bars for flowing of cleaning fluid, and a return valve formed by the lower valve plate.

Abstract: A liquid filling valve arranged on a rotating tank of liquid for filling bottles includes a spray line for directing a cleansing spray of the liquid against liquid carrying parts in the event of bottle breakage. A valve is provided in the body of the filling valve for communicating the liquid from a liquid feeder line to the spray line, the internal valve being arranged to be actuated upon breakage of a bottle.

Abstract: A double-seat valve has a first valve member and a second valve member which abut against one another after a predetermined stroke to an open position, so as to form a closed chamber. A draining conduit communicates with the thus-formed chamber. The valve members are mounted on a common shaft. One of the valve members is variable so that its seating face is displaceable relative to a point in which this valve member is mounted on the common shaft. The one valve member may be elastically deformable or corrugated.

Abstract: Successive increments of a thermoplastic tube are extruded in vertical direction from an orifice, and a first partible mold is closed about the increment immediately downstream of the orifice whereupon the increment is expanded to the shape of a first semi-finished container, while simultaneously completing the expansion of the neck region of an already filled second semi-finished container accommodated in a second partible mold downstream of the first mold and communicating with the interior of the first container, is completed. The containers are then sealed and separated from one another and the first container in the first mold is filled. The second container is discharged from the second mold and the relative positions of the molds are reversed in preparation for repetition of the preceding steps.

Abstract: The filling machine has a rotary tank containing the liquid, an annular channel surrounding the tank and containing gas having a lower pressure than the gas in the tank but higher than the atmospheric pressure, a filling unit adapted for sealing the container to be filled and including a filling pipe communicating with the interior of the tank and projecting into the container to be filled, a pressure control space communicating with the interior of the container around the filling pipe and connectable via a first control valve to the outer atmosphere, and further connectable via a second control valve to the annular channel, the second control valve being opened mechanically in response to the angular position of the rotary liquid tank and in addition being controlled during its open position by a separate timing device that closes the second valve if the mechanical control exceeds a predetermined time.

Abstract: A method of charging into containers a liquid contained in a rotary tank of a bottling machine whereby different pressures are built up in each container during the filling process so that at the beginning the liquid is discharged by the force of gravity and thereafter the pressure in the container is reduced with respect to the tank pressure to introduce a quick filling phase; after attaining a predetermined amount of charge in the container or after a certain time interval the pressure in the container is automatically increased irrespective of the rotational is automatically increased irrespective of the rotational speed of the bottling machine or of the rate of flow of the discharged liquid. The bottling machine includes an annular channel the gas pressure of which is reduced with respect to the gas pressure in the tank but is higher than the atmospheric pressure.
