Abstract: A tube cleaning apparatus for tubes and pipes installed in power plant and similar industrial equipment utilizes a rotating brush assembly fitted to one end of a rotary cable encased in a protective casing and driven at its other end in clockwise and counterclockwise rotation by a reversible motor. The invention provides a drive unit fitted with a plurality of drive rollers for engaging the protective casing and propelling the casing, cable and brush assembly at a high rate of speed into and out of each tube being cleaned. A control system for the drive unit enables the operator to manipulate the reversible motor by issuing pulses to actuate switches controlling on/off and direction of rotation of the motor. An arresting device provides for stopping forward progress of the brush assembly as it reaches the end of each tube being cleaned.

Abstract: A tube cleaning apparatus for tubes and pipes installed in power plant and similar industrial equipment utilizes a rotating brush assembly fitted to one end of a rotary cable encased in a protective casing and driven at its other end in clockwise and counterclockwise rotation by a reversible motor. The invention provides a drive head fitted with a plurality of drive rollers for engaging the protective casing and propelling the casing, cable and brush assembly at a high rate of speed into and out of each tube being cleaned. The drive rollers may be driven by a separately provided reversible motor or by the same motor used for the protective casing. A control mechanism affixed to the drive head enables the operator to manipulate the reversible motor(s) by issuing air pulses to actuate air switches controlling on/off and direction of rotation of the motor(s).

Abstract: An appliance for removing soot and ash from a fireplace including a vacuum source, an intermediate container and tubes establishing a vacuum path from a fireplace through the intermediate container to the vacuum source and a disposable bag within the intermediate container forming part of the vacuum circuit for receiving the fireplace refuse and for cooperating with a flame arrester in the container to prevent migration of hot clinkers from the vacuum cleaner and for providing a handy means for final disposal of fireplace refuse without contaminating the appliance.

Abstract: Apparatus for packaging product in an inverted, open bottom piston-type pressurized dispenser has a mechanism for pressurizing the container above the piston and for inserting a bottom closure on the open bottom and connecting it to the container body to close the open bottom.

Abstract: This invention relates to novel collapsible containers having laminated tubes and methods for making such containers. The containers are made from three preformed components which are designed and joined together in such a manner as to permit the economical manufacture of containers having a number of different tube diameters. The containers are characterized by soft shoulders that facilitate removal of the containers' contents. Preferred containers of the invention include tamper-proof closure members.
