  • Patent number: 3973311
    Abstract: A method of manufacturing self-cleaning spring filters and at least two different spring filters are disclosed. One filter formed by the method comprises a helically grooved hollow mandrel with holes in the grooves and a helical spring closely fitted therearound. The pitch of the spring convolutions is opposite to that of the mandrel grooves so that the mandrel provides lateral support to the spring equivalent to that provided by a solid cylindrical bar for maintaining uniform diameter and concentricity of the spring convolutions while eliminating lateral displacement thereof during high load operations. While this one filter is secured at its bottom to the well, a modification requires securing thereof only at its top to the well with a packer.

  • Patent number: 3973317
    Abstract: This invention provides a removal arrangement for a fastener element which includes spaced exterior portions of a first diameter with a frustoconical portion in between, the frustoconical portion tapering from the first portion to a shoulder that connects to the third portion. A resilient retainer ring fits within a groove in a grommet attachable to a workpiece and encircles the fastener element at the first and third surface portions, and is engageable with the shoulder for preventing separation of the fastener element from the retainer ring. In the removal of the fastener element, an expansible member is extended over the fastener to encircle it at the third surface portion, the expansible member presenting an exterior surface substantially that of the first diameter of the fastener, bridging between the first and second surface portions so that said fastener element can be withdrawn from the retainer ring.
