Abstract:
A beverage dispenser (10) supplies a beverage from a beverage container (12) through a piping system, wherein a device is provided for sterilizing, by heat, said piping system and a connection portion (61) of said beverage container connected to said piping system. A beverage dispenser further supplies a beverage from a beverage container (12) through a piping system and a cock (32), wherein a device is provided for sterilizing by heat said piping system and said cock (32). Thus, the piping system in the dispenser is heat-sterilized.

Abstract:
In laminated, resin-impregnated doctor blades for removing water from a grooved belt in the press part of a papermaking machine, fibers of the belt-contacting layer are oriented in the direction of travel of the belt. The doctor blade so constructed exhibits greater adhesion to the belt, an improved water-removal capability, and greater durability, when compared with a doctor blade having randomly oriented surface fibers.
Abstract:
The base layer of the cushion material is comprised of a ground body of meta-aromatic polyamide fibers and a bonding layer of substantially non-drawn meta-aromatic polyamide fibers integrated by needling. The airtight layer over the base layer comprises a non-woven fabric sheet of meta-aromatic polyamide fibers. The non-woven fabric sheet is integrated to the base layer under pressure by applying temperatures at or above the glass transition temperatures but at or below the decomposition temperatures of the constitutent fibers of the bonding layer.
Abstract:
A sludge condensation and dewatering apparatus is described which comprises a condensation unit and a dewatering unit. The condensation unit comprises a flocculating reaction tank (1) for forming a sludge flock, a first holding tank (2) slantingly arranged and upwardly inclined along the moving direction of the sludge, a conveyor for conveying the sludge flock from the flocculation tank to the holding tank for retaining the sludge flock produced by the flocculation reaction tank and an endless running screen belt (3) located just below and adjacent to the first holding tank, a dewatering unit, a solidification device (13) in communication with the first holding tank located between the condensation unit and the dewatering unit. The dewatering unit comprises an upper running piled filter cloth (4) and a lower running piled filter cloth (5), a plurality of rolls (R.sub.1 -R.sub.18) for tensioning the upper and lower filter cloths and for moving them closer to each other so as to dewater, between the two filter cloths, the condensed sludge produced by the condensation unit, and then for moving the upper and lower filter cloths apart from each other, and guiding the condensed sludge held in place between both cloths, to wind over substantially the entire circumferential surface of a perforated roll (6) having a large diameter, and a plurality of pressure rolls (P.sub.1 -P.sub.7), arranged around the upper and lower filter cloths (4) and (5) and around the perforated roll.The invention also covers the process for condensing and dewatering a sludge to obtain a cake of low water content.
