  • Patent number: 7959699
    Abstract: The present invention addresses the need for a collapsible filter that is easily assembled and installed. The collapsible filter comprises top and bottom arms rotatably attached to the top and bottom edges of two end caps. A pleated filter media is provided attached to at least one of the end caps. The present invention also addresses the need for mechanisms to facilitation the expansion of the pleated filter media, utilizing spring-like devices or other materials that may be compressed but expand to a natural state. Similarly, the present invention further addresses the need for mechanisms that allow for controlling the distance between adjacent pleats within a pleated, collapsible filter media. The present invention recognizes that a combination of these approaches may be utilized to provide a collapsible filter that is easily constructed at a manufacturing facility, assembled in the field, and installed within a system having need for a filter.

  • Patent number: 6200413
    Abstract: A system and method for polishing spherical shaped devices is disclosed. The system includes a carrier and an enclosure. The carrier has two projections so that when a device is placed between the projections, it contacts the carrier at two contact points. The enclosure matingly engages with the carrier so that it also contacts each device at two contact points. A movement system, such as a motor, provides relative movement between the carrier and the enclosure so that the four contact points polish each device. Also, the relative movement moves each device so that the device's entire outer surface is polished by the apparatus.
