Abstract: ABSTRACT     Apparatus for storage and handling pallets is disclosed.  A vertical housing capable of holding pallets in a vertical stack is equipped with openings to receive stacks of pallets and discharge pallets singly.  Vertically arranged wheels are provided on opposing sidewalls of the housing which compress when pallets pass between them.  The wheels are ganged to incrementally rotate on a selective basis, opposing wheels rotating in opposite directions.          Incremental rotation of the wheels dispenses pallets from the bottom of the stack.  Straightening bars which are driven toward the interior of the housing tend to keep the pallets in stack alignment.  A ram discharges dispensed pallets from the housing.

Abstract: IMPROVED POULTRY DEFEATHERING APPARATUS AND PROCESS   ABSTRACT       The present invention comprises a poultry defeathering apparatus for use with boilers having boiler stacks. The apparatus comprises a heat exchanger which is located proximate to the boiler stacks for exchanging heat energy contained within the boiler stacks to heated air to be used in the defeathering apparatus. A hot air mixer in communication with the heat exchanger receives the heated air and cools it with ambient air to reduce the heat energy to an appropriate level. A blower in fluid communication with the mixer receives the heated air and increases its volumetric flow rate. A scalding tank is included for scalding fowl carcasses drawn through the water within the tank. The tank also includes a hot air divider positioned near the bottom of the tank and extending longitudinally along a subtantial por-tion of the bottom, the divider being in fluid communication with the blower to receive the heated air from the blower. The divider also includes nozzles through which the heated air is injected into the scalding water to further heat and agitate the water.

Abstract: ABSTRACT OF THE DISCLOSURE     One analog signal is selected out of a plurality of analog signals by a multiplexer and a capacitor is electrically charged through such a switch as adapted to be closed/opened by a start signal, and thereafter the capacitor is caused to discharge with a constant current with the switch opened.  A level discrim-inating signal is led out when a voltage of the capacitor dis-charging goes below a predetermined discriminating level after the switch is opened.  A stop signal is generated as a result of a logical operation of the analog signal and the level discrimi-nating signal by an AND gate.  A processing circuit accepts the stop signal and calculates a digital value corresponding to a time period from the time that the switch is opened to the time that the level discriminating signal is generated, and then moves to a subsequent processing operation.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a ball valve having a valve body with a bonnet bore communicating with a through fluid bore.  A valve seat in the valve body surrounds the fluid bore axis.  A bonnet with a stem bore extending therethrough is received in the bonnet bore.  An operating stem is journalled for rotation in the stem bore.  A ball is connected to the stem and located in the fluid bore.          The ball has a through passageway.  Rotation of the stem causes the ball to rotate eccentrically between an open position at which the ball is spaced from the valve seat with its through passageway aligned with the fluid bore, and a closed position at which the ball blocks the fluid bore by being wedged into sealing engagement with the valve seat.  The ball is externally contoured to provide both a clearance from the valve body to accommodate its eccentric rotation, and a stop which is engageable with the valve body to positively locate the ball in its open position.          The invention also includes the aforesaid ball valve assembled in combination with an actuator having a linearly reciprocating piston mechanically connected to the valve stem by means of a rack and pinion.  Linear motion of the piston is limited in one direction by the sealing engagement of the ball with the valve seat, and in the opposite direction by the engagement of the ball stop with the valve body.

Abstract: ABSTRACT OF THE DISCLOSURE A device for making accurate, reproducible light reflectance measurements on an optically nonuniform specimen comprises means for holding the specimen in a fixed position. In one embodiment the specimen is illuminated by light sources that are arranged at acute angles relative to the specimen and (  ? 1°) apart in azimuth, where N = the total number of light sources. The light sources are sequentially energized and deenergized to illuminate the specimen. A light detector receives light reflecting from the surface and generates an electrical signal, which is subsequently processed. In another embodiment the light sources are arranged in pairs in which the two light sources in a pair are simultaneously energized and deenergized and the pairs are sequentially energized and deenergized. A method for measuring reflected light is also provided. The device and method are useful for making biochemical assays with reagent test strips by measuring the tone of coloration of the strips after treatment with a target substance being examined.

Abstract: Abstract of the Disclosure In the production of maleic anhydride, scale formation in an evaporator and pipes is a very difficult problem.  By the process disclosed herein, scale formation in a maleic anhydride preparation apparatus can satisfactorily be prevented, and therefore, maleic anhydride preparation apparatus can be operated continuously for a long period.  Further, it is also possible to significantly reduce the formation of fumaric acid.  The process is that when conducting the concentration and the dehydration of an aqueous solution of maleic acid, a small amount of hydrogen peroxide is added to the aqueous solution.  Scale is formed by condensation of phenols and aldehydes, and quinones and aldehydes.  Hydrogen peroxide added acts to oxydize aldehydes contained in the aqueous solution.
