Abstract: A filter for removing debris of a predetermined size from a fluid path has a first face disposed transversely in the fluid path and a second face disposed substantially parallel to the first face and displaced therefrom in the direction of fluid flow. The displacement of the second face from the first face substantially defines the strength of the filter with respect to deformation by the fluid flow. The first and second faces cooperate to define a plurality of apertures extending through the filter. The apertures are of a size to preclude passage of the debris while presenting a predetermined resistance to the fluid flow. That predetermined resistance is substantially independent of the filter's strength.

Abstract: A method and device for use in connection with a dough divider machine which continuously uses mineral oil for lubrication. The method comprises capturing mineral oil, flour, and dough contaminants which becomes mixed as the dough divider operates and filtering the captured mixture so that substantially pure mineral oil is separated from the flour, dough and contaminates. The substantially pure mineral oil is then injected back into the dough divider machine for lubrication. By comparing lost mineral oil to the weight of bakery products produced during a predetermined period, the amount of mineral oil in the bakery products is determined. The filtration method and device utilize a gravity filtration diffuser coalesence and precipitation and a suction filtration. The device is portable for use with either one or more dough divider machines and for cleaning.

Abstract: An oil reclamation device includes a housing that has an interior divided into at least two areas by a somewhat upright, generally conical vaporization plate. The area which is above the plate is a vaporization chamber at or less than atmospheric pressure. The area which is below the plate is pressurized filter area, usually the pressure is supplied by the oil pump of an engine. The bottom of the vaporization plate has a plurality of dependent heat transfer fins for creating a turbulent and uniform heat transfer from the vaporization plate to the oil. The top of the plate contains a cup terminating holes for transferring oil from the area below the plate into the cup. A covering washer forces oil in the cup to form a thin film. The transferred oil overflows the cup and runs, under gravity, down an oil-confining, helical channel which conically spirals downwardly.
