Abstract: A conduit cleaning device includes a body with a central portion, a forward portion comprising a neck, and a rear portion with a hose fitting adapted for connection to an associated hose. The body includes a main flow passage that extends through the hose fitting, through the central portion, and into the neck. A rotor is rotatably supported on the neck. The rotor includes at least one rotor nozzle orifice in fluid communication with the main flow passage. A centering device is secured to the central portion of the body. The centering device includes a core and a plurality of fins that project outwardly from the core. The core of the centering device includes a mounting bore that extends therethrough, wherein at least part of the hose fitting is located within the mounting bore of the core and an annular space is defined between the hose fitting and an inner surface of the mounting bore of the core.

Abstract: Spray nozzle for high pressure cleaning. The spray nozzle comprises a stationary body having an inlet portion and a tubular stem or outlet portion, which has therein a bore and a counterbore, respectively; a plurality of laterally extending ports extending from the counterbore to the exterior of the stem portion for discharge of high pressure water; a rotor having aligned tubular end portions defining a bore and a central rib portion of enlarged diameter having an annular channel or reservoir for water therein, and a plurality of orifices extending from said annular channel so configured as to cause self-rotation of the rotor; and an end cap and a machine screw to hold the rotor in place and restrain it from axial movement. Flow restrictors slow down the speed at which the rotor rotates by momentarily obstructing the discharge of water from the ports in the stem portion as the flow restrictors cross the discharge paths.

Abstract: A filling tube for use in a container filling machine in which the tube is vertically disposed within a container as the container is being filled with a liquid. The lower end of the tube is adapted for insertion downwardly into the container and the upper end of the tube is provided with means for attachment to the filling machine. The lower end of the tube has an externally threaded portion with a pair of annular sealing portions, one sealing portion on either side of the threaded portion. A protective end tip member formed of a soft, low moisture absorbent material is secured to the lower end of the tube. The soft tip member minimizes damage to glass containers as the filling tube is inserted into the container. The tip member has an internally threaded portion which engages the externally threaded portion of the tube to secure the tip to the tube.

Abstract: A vent tube for a container filling machine in which the fill height is adjusted by the replacement of a removable lower tip. The vent tube has an upper tubular body with an interior axial passage through which gas is vented. The removable tip is attached to the body by insertion into a socket formed in the lower end of the passage. The tip is a tubular member with a wall surrounding an interior axial passage which communicates with the passage of the tube body. An opening is provided through the wall of the tip at the level of the predetermined fill height. Locking means are provided by which the tip is removably held within the socket of the tube body.
