Abstract: The poultry gizzard with the gut and stomach attached descends along a chute having a slot through which the gut hangs from the gizzard. Below the lower end of the chute are a pair of rolls having the tops rotating toward each other. These rolls have interengaging gears at each end with spaced, ribbed intermediate portions. The first pair of gears detaches the gut and the second pair of gears detaches the stomach. A second pair of rolls coaxial with the first pair have their upstream portions spaced apart and interengaging gears at the far end. These rolls rotate so that their tops move away from each other. A rotary cutting knife extends upwardly through the space between the first portions of the second pair of rolls. Downstream from the second pair of rolls are rails to receive the split and opened gizzard. A cleaning spray is directed upwardly through the rails. At the far end of the rails are a pair of peeling rolls positioned at right angles to the rails.

Abstract: An anticipatory flammable gas detection system is provided for quickly determining whether the rise rate of gas concentration will approach a potentially hazardous level. The system includes a detector for determining the rise rate of the gas concentration and a comparator for determining whether the rise rate exceeds a potentially hazardous level. An integrator or multivibrator is provided for determining how long the rise rate exceeds a predetermined value. If the rise rate exceeds the predetermined hazardous rate of rise for more than a predetermined period of time, an alarm signal is generated. Prevention of false alarms is accomplished by providing another comparator which determines whether the magnitude of gas concentration exceeds a preselected percentage of the lower flammable limit. Should the magnitude be less than the preselected percentage, the alarm signal will not be generated.

Abstract: A sleeve is rotatably mounted on the main body and the two define a reservoir cavity therebetween. Projections integral with the body extend radially through the reservoir cavity to contact the inner wall of the sleeve. Spaced axially along the cylinder are a plurality of openings which extend through the projections from the cylinder cavity to the outer end of the projections. On the inner wall of the sleeve in juxtaposition to the outer end of the openings are a plurality of generally annular grooves. The oil path or duct for release of oil from the cylinder cavity to the reservoir cavity when the piston moves inwardly is through the openings and those parts of the grooves at the distal ends of the projections. In one embodiment these grooves vary in cross-sectional size throughout their length. In another embodiment they are helical, at a slight angle to the axis of rotation.

Abstract: Side walls of spaced horizontal rails inclined inwardly to a horizontal platform provide a safe climbing challenge to children on a complex recreation structure. A vertical pole in the center of an opening in the platform offers the thrill of sliding down into the interior of the structure. An open doorway provides access to the interior. The interrelated complexity of the structure offers challenge and stimulation to the children. The side walls include spaced horizontal rails each of which rests upon and extends beyond a rail of adjoining sides. A horizontal user's platform is positioned at the uppermost limit of the walls spanning an area defined by the tops of the walls. The pole is unsupported by the platform and the walls.

Abstract: A first bracket is secured to one of a pair of doors hinged to a door frame for closing the same; a second bracket is secured to the other of the pair of doors; and the brackets are disposed in overlapping relationship, and include means which are interengageable, when the doors are in closed position.

Abstract: A vibratory plate includes a ground plate, a vibration generator adjacent the front of the ground plate and a motor driving the vibration generator. The ground plate includes a sole plate, an upwardly inclined portion at the rear of the sole plate, two successive upwardly inclined portions at the front of the sole plate and an upwardly and rearwardly inclined portion from the front of the ground plate to the casing of the vibration generator. Extending downwardly from the casing of the vibration generator to the ground plate are supporting ribs positioned in the planes of the bearings of the vibration generator. A transverse rib extends upwardly from the ground plate at the rear of the supporting ribs. The ground plate, the ribs and the casing are an integral unit. In one embodiment that unit is cast aluminum with a steel facing on the bottom of the sole plate. In a second embodiment they are fiberglass reinforced plastic with a steel facing on the bottom of the sole plate.

Abstract: The engine crankcase is connected to the intake manifold of carburetor engines through a poppet valve with spring adjusted so that the valve is closed while starting, partly open while idling, closed during acceleration and wide open during deceleration whereby to maintain relatively uniform optimum vacuum in the manifold. The crankcase is also connected with the intake air cleaner. Both sides of V-type engines are connected to the valve inlet.

Abstract: Improved septa for chromatographic apparatus and procedures comprise disc or cylindrical bodies of silicone rubber with a coating of polyimide which may in turn be covered by a coating of Teflon.

Abstract: Immediately downstream of the high pressure fuel pump and electrical signal is generated by that part of the fuel pressure impulse intended to cause the fuel injection valve to close. That electrical signal energizes a solenoid causing the opening of a pressure relief valve incorporated into the valve body of the fuel injection valve. The relief valve is timed to open upon the closing of the fuel injection valve. In a multi-cylinder engine, the pressure relief valves for all cylinders are opened simultaneously. The pressure relief valves discharge into a pressure relief chamber, which may be individual for each valve or a common manifold communicating with the fuel supply.

Abstract: Apparatus for clearing drain lines includes an appliance which may be held in sealed engagement over a drain opening and actuated with a sudden burst of gas pressure. The appliance includes a pressure chamber which can discharge into a sealing ring and which for each operation is initially closed off from the sealing ring by a rupturable metal diaphragm. While the appliance is held by hand with its pressure ring firmly sealed around the drain opening, gas pressure is increased in the pressure chamber until the diaphragm suddenly ruptures to release the compressed gas into the drain with a sudden hammer-like action. The gas pressure may be supplied from a pressure can or by pump. This metal diaphragm may be a conventional jar-cap as used for home canning, except accurately scored to rupture at a predetermined pressure.

Abstract: The bolt of a door latch or lock is made laterally adjustable to ensure both proper latching operation upon closing the door and also reasonably firm engagement of the catch with the fixed stop to ensure firm holding without vibratory or rattling movement. The adjustment is accomplished by adjusting the angle of emergence of the bolt with respect to the latch structure, e.g., the bolt case. The adjustment capability allows greater tolerance in the mounting of the latch upon the door.

Abstract: A pair of rolls extend upstream from beyond the upstream end of a generally horizontal feed trough. The configuration and the rotation of the rolls is such that the gizzard and stomach are supported on the tops of the rolls while the gut and gullet, including the crop, depend below the rolls. The rotation of the rolls moves the stomach and gizzard onto the feed trough. Below the feed trough are a pair of gears rotating about vertical axes with the nip of the gears positioned below a slot in the feed trough. These gears pull the gut and gullet in a downstream direction and as they do so a knife below the gears severs the gut and gullet.
