Abstract: Abstract Thin photoconductive insulator layers are desirably used because of the reduced amount of materials necessary and their enhanced ability for light transmissi-vity.  However, the thin construction tends to reduce the amount of charge that such a photoconductive layer can support.  The use of a combined porous and non-porous barrier-charge transport layer below said photoconductive insulator layer enables higher levels of charging in a photoconductive construction.

Abstract: INSERTER WITH IMPROVED RAM MECHANISM                   ABSTRACT OF THE DISCLOSURE     An improved reciprocating ram for an envelope inserter in-eludes a pusher which drives an enclosure from a ram pick-up station to an envelope station.  Cycle time has been reduced by providing a ram return path which is beneath the elevation of the pick-up station.  Thus, the next enclosure is fed to the pick-up station before the ram has completed its return stroke.  The ram mechanism includes a ram carriage which rides along a pair of longitudinal rods.  A ram block carrying a ram blade rides with the carriage and is keyed for vertical movement relative to the carriage.  The block includes a follower which engages a longitudinal box cam having a latch adjacent its en-velope station end.  When the ram blade reaches the envelope station, the latch directs the follower to a lower elevation camming surface for the return stroke.  The pusher is secured to the ram blade by a leaf spring catch which engages a grating on the undersurface of the blade.  The pusher position is adjusted by depressing the leaf spring to release the catch.

Abstract: HYDRAULIC BEAN CLEANING  PROCESS AND APPARATUS                          ABSTRACT          A hydraulic bean cleaner for removing rocks from beans has a hopper for gravity-feeding uncleaned beans down an inner cylindrical tube into a cylindrical separator tank.  The inner tube has a bean discharge opening centered just above the bottom of the tank.  An outer cylindrical tube concentrically surrounds the inner tube, providing an annular passageway therebetween and a water discharge opening surrounding the bean discharge opening.  A first vibrator vibrates the tubes as a unit to help feed the beans down the inner tube.  A second vibrator vibrates the hopper independently of the tubes to aid in feeding the beans to the inner tube.  The beans drop into the bottom of the tank and water is expelled downwardly into the tank around them.          The water entrains and fluidizes the beans, carrying them laterally away from the bean discharge opening and buoy-ing them upwardly.  The turbulent flow of water agitates the beans.  Agitation of the fluidized beans creates spaces between the beans through which rocks can sift downward to the bottom of the tank against the upward flow of the water.  Near the top of the tank the beans and water overflow across a spillway into a colander.  The colander strains the water into a sump.  A pump recirculates the water in the sump back to the outer tube.

Abstract: ABSTRACT Applicant has provided a ballast circuit for fluorescent lights made up of the combination of (1) a source of electrical energy, (2) a resonant circuit, (3) a switch means for connecting the source of electricity to the resonant circuit, (4) means to connect the resonant circuit to a load, (5) a resonant current monitor controlling the switch means in synchronism with the resonant current so that the switch means switches the resonant current when the resonant current passes through zero. The resonant current monitor is a current transformer having a primary winding connected in series with the resonant circuit and two secondary winding connected to the bases of the two switching transistors in a two transistor inverter circuit at a polarity that will switch one of the transistors on and the other off at the time current passes through zero. This is the optimum time to switch the transistors since the current flowing through the transistors is passing through zero at that time and therefore the transistors operate at maximum efficiency and there are minimum switching losses and improves the efficiency of the circuit. The circuit will automatically adjust the switching frequency to the changed resonant frequency should the value of the inductor or the capacitor degrade and therefore change, and the switching losses will therefore be maintained at minimum.
