Abstract: ABSTRACT OF THE DISCLOSURE    A submersible pump assembly has pressure compensator features to avoid negative pressure at the top of the tool during installation.  The submersible pump assembly has an electric motor contained within a lubricant filled motor chamber below a pump.  A pressure compensator chamber is located below the motor chamber and separated by a parti-tion.  The pressure compensator chamber is also filled with lubricant.  A passage bypasses the partition and leads to the motor chamber above the motor.  A bellows is mounted in the pressure compensator chamber with its mouth facing upwardly.  A port extends from the exter-ior of the pressure compensator chamber to the interior of the bellows for admitting well fluid.  Also, the bel-lows may be filled with a heavy fluid during installation so as to retard contraction of the bellows if the tool is suddenly jerked to a stop.  The bypass passage is not re-quired in this embodiment.

Abstract: INCREMENTAL ROTARY ENCODER            Abstract of the Disclosure A field replaceable encoder including a slotted housing having a pair of passages therethrough essentially perpendicular to the longitudinal axis of the housing, is attachable to the frame of a machine having a rotatable shaft to which the encoder is to be mounted. Attached to the housing is an accurate stationary mask, the mask having slits which are aligned with the passages in the housing.  The mask includes an accurately dimensioned aperture for locating the mask, and thus the housing, on a bearing on the rotatably mounted shaft.  A pair of light sources and a pair of light detectors are mounted on opposite sides of the housing aligned with the passages and slits in the mask.  A huh, to which is attached a rotating disc, is connected to the rotating shaft, the disc being mounted in the slotted housing so that interdigitated opaque and transparent portions align with the slits of the mask, and thus the light sources and light detectors.  In the preferred embodiment, the light sources are mounted in the passages (tunnel like in formation) which converge at their outlets and which prevents having to employ collimated light sources while inhibiting cross-talk between the detectors and adjacent sources allowing for close spacing of the source pair and the detector pair.

Abstract: AN IMPROVED BUSHING WITH SELF-TAPPING THREADS                   Abstract of the Disclosure An improved bushing engageable in the cylindrical bore of a housing and having a smooth axially aligned internal bore to which a rotatable shaft is journaled.  The improved bushing contains a stepped outer circumferential surface having a smooth circular lead surface and a larger diameter, self-tapping threaded surface.  The lead surface is used to align the bushing in the cylindrical bore and is approximately of the same diameter as the cylindrical bore.  The self-tapping threaded surface permits the bushing to positively engage the housing and thereby axially align the shaft which is journaled to it.  The improved bushing also includes a tool receiving end formed adjacent to the self-tapping threaded surface which accepts a tool to enable the bushing to be screwed into the housing.

Abstract: MOTORIZED OVEN DOOR LATCH AND    CONTROL CIRCUIT FOR SAME                 ABSTRACT OF THE DISCLOSURE         An L-shaped hooked end of a latch rod, rotatably supported by a range body, engages a door-supported cam sur-face as the rod is rotated on its longitudinal axis by a motor to effect oven door locking.  The cam surface is fixed at and radially spaced from the center of an elongated member whose ends are fastened to the oven door.  As the latch hook engages and rides the cam surface, the elongated member is placed in torsion to provide a biasing force that maintains the locked oven door in tight sealing engagement with the range body.  The motor rotating the latch rod to effect oven door locking and unlocking is actuated solely by operator manipulation of the oven thermostat control apart from the oven selector and timer controls.

Abstract: Elevator Cab Abstract An elevator cab is constructed of a thin, somewhat semirigid skeleton.  Expanded core plastic panels are attached to the skeleton, thereby forming a very light and rigid cab.  These panels are attached by means of releasable hook-like fasteners, thus permitting selective removal of the panels from the skeleton. Due to strategic location of the fasteners on the skeleton, the panels, when attached to the skeleton, create a rigid cab.

Abstract: METHOD AND APPARATUS FOR ERASING         INK JET PRINTING                    Abstract The technology encompassed by the practice of this invention includes apparatus for ink jet printing under the control of electronic cir-cuitry and ink jet printing under the control of an operator, for example, a typewriter.  Broadly, the technology presented in accordance with the principles of this invention utilizes an ink eradicator which removes indicia of the ink by chemical reaction.  The character of the erad-icator fluid is such that another fluid may be utilized either together therewith or separately to neutralize the residue from the chemical reaction so that printing can readily be ac-complished in the location where erasure has occurred.  Specifically, practice of this inven-tion is contemplated with means that applies the eradicator fluid over the location on a surface where printing has occurred by ink jet droplets as well as over an entire area thereon within which there is ink jet printing for which a change is to be achieved.  For exemplary em-bodiments of this invention, the eradicator fluid is applied by a wick from a reservoir and the chemical reaction is enhanced by heating the location for the erasure by an external heating means.

Abstract: METHOD FOR PRODUCING FUNGI          Abstract Nutrients for supporting fungi growth, and particularly mushroom growth, are provided by a liquid nutrient comprising the product of a thermophilic digestion process. The liquid nutrient is contacted with and absorbed in a support medium to form a growing bed. The liquid nutrient is inoculated with spawn of the particular fungi to be grown. The inoculated product is then maintained under temperature and humidity conditions that promote mycelia growth. Once mycelia appear, the growing bed can be cased to promote the growth of fruiting bodies. The growing bed can be replaced on a batch basis. Alternatively, the bed can be irrigated on an intermittent or continous basis to replenish the nutrient supply.
