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: Bottle filling machines are known in which bottles travel in a circular path and, while doing so, are filled with liquid under pressure, e.g. beer, by individually associated filler mechanisms. If, because of the pressure, a bottle explodes, glass fragments can adhere to the associated filler mechanism and it is important that these be removed, to keep glass from entering the next bottle coming in. Resort has been made to using water sprays but heretofore such means have been relatively ineffective and in some cases, very messy in operation. The present invention provides apparatus which can thoroughly clean a filler mechanism in the event of an exploding bottle. A broken bottle sensor is located between the infeed mechanism and outfeed mechanism on the bottle filling machine.

Abstract: A dishwashing apparatus is provided with a float controlled liquid inlet valve. The float includes a centrally located, downwardly extending, stem portion which extends through the inner aperture of a standpipe associated with the bottom wall of the liquid container. A cap portion of the float surrounds and encloses the upper extremity of the standpipe and prevents spraying liquid from escaping the liquid container through the standpipe aperture. A floatation chamber is axially spaced below the cap portion of the float and is connected thereto by a plurality of arms. The spacing of the float chamber from the cap defines openings which allow liquid to wash through the inner section of the float and around the standpipe to remove debris.

Abstract: In a new spraying apparatus a spray boom structure supporting the spray dispensers for liquid or finely divided spray material is supported by an air pressured flexible bag skirt attached to the structure and forming an enclosure into which the spray dispensers discharge to minimize drift of the sprayed material and permitting increased speed of the apparatus over the ground. The bag skirt structure also "averages out" irregularities in the surface so that a more uniform spray pattern is achieved. Air is fed into the enclosure from the leading bag skirt part via an elongated aperture close to the ground and from the trailing bag skirt part from an elongated aperture close to the enclosure roof. The weight of the fan and its housing supplying the pressurized air is supported separately from the boom. The boom structure may comprise hinged portions that can be moved to a vertical storage position, and it may also include arcuate downwardly extending support members.

Abstract: A filter press provided with a spray cleansing device of the kind described in U.S. Pat. No. 4,107,042 granted Aug. 15, 1978 to wash filter plates of the press disposed in a stack on horizontal guides in which the spray device comprises a support frame which moves along the stack of plates on the horizontal guides. Two branch conduits of the device are fitted with nozzles and surround a plate being washed to spray wash the plate simultaneously from both sides. The specific improvement in the present invention comprises a novel spray water catch basin which has a width more than twice the spacing between the branch conduits. Movable segments on both sides of the catch basin are provided which may be pivoted about a perpendicular axis to adapt the catch basin to many locations along the filter press.

Abstract: In a known type of bottle filling machine, a bottle travels on a platform which is raised so that the bottle encircles a filler tube and sealingly engages a filler bell which is slidable up and down on the filler tube. If a bottle explodes during filling, particles of glass can adhere to the filler tube and the filler bell and it is obviously desirable to clean off these glass particles so that they cannot get into a subsequent bottle. However, with the presently known filler machine, when a bottle explodes the filler bell drops to the end of the filler tube and is suspended just above the platform on which a bottle rides. This makes access to the underside of the bell difficult and hence makes it difficult to spray water to clean off the underside of the filler bell and the filler tube. At present, it is known to have an operator manually flush the tube and bell with a low pressure water spray but this is a slow and inefficient operation.

Abstract: Apparatus for applying a liquid from a tank to a nozzle which is adapted to be held against a surface of a porous material for deep penetration of the surface by the liquid. An air stream is provided by a blower and aspirates the liquid from the tank. A fan is positioned in the path of the air stream which flows through an apertured plate. The rotation of the fan caused by the flowing air stream results in the blades of the fan covering and uncovering, in succession, the apertures of the plate, thereby resulting in a pulsating delivery of the liquid-air mixture to the surface of the porous material for deep penetration thereof by the liquid.
