Title: Wire element continuous band filter - having endless wire between two rollers with solids retention on wire
Inventor: MIGULE ALBRECHT DIPL ING
IPC: B01D33/04
Filed: 1975-06-12
Abstract: Continuous separation of solids from a liquid using band filter. This consists of an endless wire which is wound round two parallel rollers driven by a motor. The wire is cooled around the rollers, running from side to side and then returned to the start. The wires run parallel across the rollers. The liquid flows through the gaps between adjacent wire runs while the solids are retained by the wire. They pass over to the end roller where they drop off through gravity. A comb is used to remove residual particles left between wires, the teeth of the comb being in contact with the wire. This cleaning action is backed up by the use of a pumped supply of waste liquor spray onto the lower part of the coil. Device is for continuous separation of solids from liquids. Wire coil effectively breaks and remakes the medium continuously and coupled with combing and washing ensures good cleaning.

Title: Free standing filter - for large vols. of gas, esp. air, with elements in zig-zag arrangement
Inventor: NOEL GERARD
IPC: B01D46/42
Filed: 1975-07-16
Abstract: The filter consists of a housing and filter elements. The elements, which are provided with frames, are located in guide rails in the housing. The housing is made up of only a support structure which comprises front and rear vertical members, horizontal cross-members, horizontal 'U' section strips mounted on the rear face of the housing, and the 'V' section guide rails into which the elements slide. The guide rails have inclined end faces which bear against the front and rear vertical members between each front and rear pair of which the rails extend. The filter elements are self sealing. The seal is formed by a loose extension of the filter fabric beyond the front and rear frame strips which is compressed at the rear in the 'U' strips, which each accept the rear frame strips of two filter elements. The front frame edge of each alternate element is turned upwards through an angle to form a surface for the other element to bear against. The structure is quickly and easily assembled from standard parts. The absence of intermediate vertical walls reduces flow resistance and simplifies construction.
