Abstract: An adapter structure for a first opening in a frame includes a stem and a plurality of flexible wings. The stem is configured to be received in the first opening of the frame and defines a longitudinal axis. The stem includes a second opening extending at least partially therethrough along the longitudinal axis and configured to receive a fastener. The plurality of flexible wings extend radially outward from the stem.

Abstract: A process for preparing fertilizer from fish, and a fertilizer prepared from said process, is disclosed. The fertilizer is for use on soil and plants. The process involves hydrolysis of fish with a phosphorus containing acid, preferably an inorganic phosphorus based acid, under normal ambient conditions. Typically, phosphoric acid is used. The fertilizer prepared from the disclosed process contains 1 to 10% by weight of the phosphorus based acid.

Abstract: A device and method for the treatment of fluids using electrostatic fields generated by a high voltage electric current, which reduces or eliminates calcification, scaling and microbiological contamination. A high voltage negative DC current is applied to a core electrode, generating an electrostatic field which traverses a dielectric sleeve surrounding the core electrode and charges the exterior surface of the dielectric sleeve. Organic and inorganic particles as well as biological contaminants which pass through the electrostatic field or contact the surface of the dielectric sleeve are then charged. Fluid flowing through the device is agitated by a combination of spiral vane sections surrounding the dielectric sleeve and helical baffle sections lining the housing wall. Charged inorganic particles coalesce into spherical aggregates which resist adhesion to pipes and vessels and can be filtered by techniques such as RO without deteriorating the filter membrane.
