Abstract: A by-pass control system for a meat injection system has a variable speed pump that transports fluid to a meat injection machine. Excess fluid is transported to a by-pass control valve. The valve has a moveable piston disposed therein that separates the valve into a fluid chamber and an air chamber. The piston moves back and forth based on the relationship between fluid pressure and air pressure. Sensors are disposed within or through the lid or the valve to sense the position of the piston. A controller is connected to the sensors and the variable speed pump and adjusts the speed of the pump based on the position of the piston.

Abstract: A frothing device adaptable to a steam outlet for producing milk froth comprising a steam inlet, a milk inlet, an air inlet, a vacuum chamber adapted to receive steam, liquid milk and air therein, a restriction with a limited cross-section adapted for conducting the product there through at high velocity, an emulsifying chamber; the emulsifying chamber having an outlet for draining the product froth out of the chamber and a froth flow regulation system configured for breaking the kinetic energy of the froth stream and for changing its direction sufficiently so that the froth is gently delivered out of the device. The frothing device can be mounted on a coffee machine to deliver cappuccino upon a push of a button.

Abstract: An apparatus for dehulling grass seed utilizing a vibrated housing having an elongated chamber. The interior of the chamber is accessible through openings or ports that provide a plurality of entries and exits for the processing of grass seed. Grass seed is dehulled by a housing mounted pneumatic accelerator that removes the hulls from the seeds. Hulls and seeds are then directed into the interior of the chamber wherein separation of seeds from hulls and hulls containing seeds occurs. Seeds are discharged from the chamber and the hulls containing seeds are returned to the pneumatic accelerator for repeating the dehulling process.

Abstract: A batch seed dehuller for seed testing purposes is provided and includes an upright cylindrical chamber merging downwardly into the upper major diameter end of an inverted frusto-conical chamber which in turn merges downwardly into a downwardly opening generally cylindrical passage of smaller diameter than the cylindrical chamber. An annular top wall closes the outer peripheral portion of the upper end of the cylindrical chamber and includes an inner periphery downwardly from which a tubular vortex finder extends to a level spaced above the frusto-conical chamber. The cylindrical passage includes a small diameter generally radially inwardly opening compressed air inlet intermediate the upper and lower ends thereof and a lateral airflow outlet of greater cross-sectional area than the inlet opening generally radially outwardly of the cylindrical passage substantially diametrically opposite the inlet.

Abstract: Blood from a slaughterhouse is gelatinized in a gelatinizer by adding steam and heat thereto. The blood is blown by additional steam pressure from the gelatinizer into an auger press thereby force feeding the press. The gelatinous mass is first squeezed gently to remove the liquids therefrom and during the latter stages is pressed more firmly to remove more of the liquids. The liquids are directed to a filter tank, while the solid gelatinous mass is directed to an offal cooker with offal.
