Abstract: A pistachio huller provided wherein a means (16) having projections (18) pushes unhulled nuts between the surface of the means having projections and a surface of a means (30) having channels (28), the channels being wider than the pistachio nuts to be hulled. The projections protrude into the channels and the hulls are ruptured and abraded through contact between the surface of the means with projections and the surface of the channels whereby the nuts are hulled.

Abstract: An offset current which is 180.degree. out of phase with the leakage current for a motorized bed circuit is created through the use of an additional transformer winding and series resistor which is connected between the neutral conductor and ground conductor. As the circuit is connected in the reverse polarity condition for testing to UL standards, the offset current is injected into the ground conductor which cancels out a portion of the leakage current from the motors to thereby bring it within testing standards. In the normal connection condition, the injected offset current is additive to the leakage current, although the normal leakage current is much less than the reverse polarity connection leakage current so that the overall leakage current in the normal connection condition remains within test standards.

Abstract: A pistachio huller is provided wherein a means having projections pushes unhulled nuts between the surface of the means having projections and a surface of a means having slots, the slots being narrower than the pistachio nuts to be hulled. The projections protrude into the slots and the hulls are ruptured and abraded through contact between the surface of the means with projection and the surface of the strips forming the means having slots whereby the nuts are hulled.
