Abstract: The invention is a modular card processing and attaching system configured to provide uninterrupted workflow in the feeding and subsequent attaching of cards to carriers for the formation of a mailpiece. The modular card processing and attaching system is further configured to be incorporated into a production mail inserter system, such that attached card and carrier mailpieces may be subsequently sorted and/or inserted into a mailable envelope or packages to be mailed.

Abstract: A collation folding device comprising one or more fold rollers mounted in fixed positions. Below and adjacent to the fold rollers are adjustable nip rollers to form nip spacing between the rollers. The adjustable nip roller is mounted on a nip axis shaft. An adjustment mechanism is used for moving the nip axis shaft to adjust the nip spacing. The nip adjustment mechanism includes a bearing block cam follower on which the nip axis shaft is fixedly mounted and supported. An eccentric cam in operative contact with the bearing block cam follower. Rotation of the eccentric cam on the eccentric cam axis drives the bearing block cam follower in its linear motion to adjust the nip spacing.

Abstract: Pivoting brush heads and associated machines in which cleaning of interior tube surfaces occurs by a forward non-cleaning pass of a pivoting brush head through a tube followed by a reverse cleaning pass where the pivoting brush head engages and cleans the interior surface. The pivoting brush head has a first position for the forward pass producing minimum engagement of interior tube surfaces, and a second position for the reverse pass of full cleaning engagement with the interior tube surfaces.

Abstract: An apparatus and method for cleaning coils and fins of outdoor condenser units and the like in locations without electrical service wherein the apparatus comprises containers for water and cleaning chemical, a plumbing system for preparing and delivering a cleaning mixture, an electrical system for power, and wherein the method provides for cleaning coils by directing cleaning mixture through the coils in counter-flow to cooling air drawn through the coils by a condenser unit fan.

Abstract: A tube cleaning machine in which cleaning interior tube surfaces occurs by a forward non-cleaning pass of cleaning implement through work tube followed by reverse cleaning pass where implement engages and cleans interior surface. Cleaning implement has first position for forward pass producing minimum engagement of interior fire-tube surface, and a second position for reverse pass of full cleaning engagement with interior fire-tube surface. A distance indicator enables operator to select distance of forward pass of cleaning implement to correspond with tube length.
