This invention relates to a method and apparatus for processing photosensitive material and, in particular, to a compact table top apparatus for developing silver halide photosensitive materials, such as a sheet or web of photographic film or paper or plate, and its use.

A fitting which can be snap-fit into a housing and used as a journal bearing, bushing fastener, or other machine element, comprising a unitary annular body of a resilient polymeric material, with molecular weight greater than 1,000,000. The body has two intersecting peripheral surfaces. A protuberance is located at such intersection to removably retain the body in the housing. The disclosures include steps for making the article. The article features greatly improved wear and life-cycle characteristics over similarly used prior art.
