Abstract: A rodenticidal composition comprising a carbon dioxide release agent and a carrier may be disclosed. A method of controlling rodents at a locus by applying the composition of the disclosure may be disclosed.

Abstract: A variable compression disc filter housing secures a circumferentially welded composite layer of filter disc material for filtering a small amount of liquid for determining the optimum filter media material for specific production applications.

Abstract: A lateral dispersion filter basket provides turbulence at the bottom of the filter basket reducing strain on the bottom seam of the filter bag disposed therein causing the particulate being filtered to move up along the vertical walls of the filter bag.

Abstract: A washing station and method for removing debris and oil from landscape maintenance equipment vehicles includes a self-contained pressurized washing system that separates the washing water from solids, washes the solids, captures the oil and debris, recycles the filtered water and prevents contamination of the surrounding area.

Abstract: A simple, economical acid rapid method for determining the contaminate particle size appearing in a fluid being filtered includes a filter housing that eliminates fluid bypass with a multi-layered laminated filter disposed therein.

Abstract: A safety apparatus for pressurized filter vessels includes a protective shroud, a mechanical and electrical interlock device that prevents the opening of the filter vessel cover unless the input and output port valves are closed and electrical power to the pressurizing pump is disconnected.

Abstract: A laminated filter material may be used in seamless filter bags in order to increase the strength and filtering ability of a pressurized filter system.

Abstract: A self-sealing washer for use on a fluid containing housing includes a semi-rigid circular member having a horizontal portion and a relatively short vertical portion disposed at the distal edge thereof suitable to be received into a channel provided on a flat surface of the housing. The horizontal portion of the circular member includes a centrally disposed through aperture to receive the screw therein, the screw has a relatively large head portion. A first elevation portion is provided on the circular member which is disposed remote from the distal edge and a second elevation portion generally centrally disposed within the first elevation portion which terminates in a relatively sharp edge. Preferably the second elevation portion is higher than the first elevation portion.

Abstract: A seamless filter bag with integral sealing means for use in a filter housing utilizing a filter basket includes an integral sealing means, which is part of a semi-rigid ring member affixed to a filter bag. Upon closing the filter housing cover a complete seal circumscribing the filter basket and filter housing cover is provided.

Abstract: A seamless filter bag having a removable, reusable ring includes a heat sealed filter bag open on one end adapted to receive a removable ring therein. Openings are provided in the filter bag which receive inwardly extending protrusions on the ring thereby maintaining the integrity of the filter bag material. A handle adapted to be received by the inwardly extending protrusions on the filter ring permits the removal of the filter bag together with the ring and any material retained in the bag from a conventional filter basket.
