Abstract: AUGER CONVEYOR FOR A CROP HARVESTER              Abstract of the Disclosure The cross auger of a corn head for a combine is made up of two independent identical but opposite-hand auger sections, each separately driven and with their inner ends sharing a common central suspension member.  The inner end of each section includes a bearing plate which abuts its respective side of the suspension member and engages a pair of support ledges for support and location.  A single fastener locks the two auger sections in position.  A common central annular shield axially overlaps the inner ends of the tubes of both auger sections.  An upper portion of the shield is easily removable to permit the inner end of either auger section to be lifted out of engagement with the support hanger without disturbing the remaining auger section.

Abstract: ABSTRACT OF THE DISCLOSURE     A slack adjuster for connecting an air actuated piston rod to rotate a cam shaft in a vehicle brake system has a worm gear mounted to rotate in a housing and connected to the cam shaft, the worm gear and the cam shaft rotating together about a first axis.  A shaft rotatable in the housing about a second axis perpendicular to the first axis has a worm intermediate its ends engaged with the worm gear.  A drive and a coupling are mounted coaxially to rotate on the shaft and a ratchet interconnects the drive and the coupling for allowing the drive to rotate about the shaft axis relative to the coupling in only one direction.  A slip surface between the coupling and the shaft slips when a predetermined rotational force is exerted between the coupling and the shaft.  A clevis connects the housing to the piston rod at a predetermined point spaced from the first axis, a link is connected to the clevis at a point spaced from the connection between the clevis and the housing, and the link and the drive are connected for rotating the drive and the coupling as the vehicle brakes are applied.

Abstract: ABSTRACT OF THE DISCLOSURE           A compact refraction instrument for use in both the objective and subjective examination of human eyes.  The instrument incorporates an alignment mode, a retinoscopy mode, a distance mode and near mode.  For carrying out the functions associated with these modes, the instrument includes a Brewster stereoscope and a system for supporting a plurality of binocular/ monocular vision testing slides.  Positioned along the pair of optical paths between the Brewster stereoscope and the slide supporting system are:  a first mask/septum system; a mode change system; a second mask/septum system; and a horizontal/ vertical target mask system.  The instrument also includes a refractor system and apparatus for suspending the refractor system in the optical paths before the Brewster stereoscope.          The slide supporting system includes two rotatable concentric drums.  The mode change system includes a first mirror for folding the optical paths when the instrument is used for subjective testing at a distance and near vision testing.          Alternately, for retinoscopic examination, the paths are folded by a pair of mirrors having an opening therebetween.  The Brewster stereoscope and both septums are rotatable so that they can be inserted into or removed from the optical paths as required by the various modes of operation of the instrument.

Abstract: COMBUSTION HEATING SYSTEM              Abstract of the Disclosure A porous ceramic heating reactor is positioned within a tubular casing to contain the flame and the end prod-ucts of combustion.  A flattened portion of the casing extends substantially past the reactor to provide for further transfer of heat through the casing wall from the hot exhaust gases and to carry those exhaust gases to a safe point of exhaustion.  The unit is essentially modular so that any number can be selected for an installation.  The casing configuration enhances turbu-lent flow of the hot gaseous products of combustion. Turbulent flow increases heat transfer to and through the walls of the casing to the boilder or other area to be heated.  The size and shape of the tubular casing provides an explosion proof, leak proof, efficient heat transfer device.  Each reactor has a spark plug one of whose elements is a bi-metallic strip. In a multi-unit installation the spark plugs are connected in parallel across a spark generator.  As the spark seeks the smallest gap, one will spark first, initiate combustion, and in response to the heat expand its gap and the spark will shift to the next smallest gap.  The sequence will continue for as many reactors as are in the system.  A normally open pressure responsive switch is connected to sense the difference in pressure between the fuel inlet line to the reactor and the combustion chamber within the casing.  If the pressure differ-ential is not maintained, the switch opens and shuts down the system.  However, a slow blow fuse connected across the contacts of the pressure responsive switch prevents shutdown for a short 15 second time period sufficient to permit the initiation of ignition.                             -i-

In the safety system, an alternating current generator transmits a predetermined frequency signal over the pair of conductors to the mining apparatus.  A filter which passes the prede-termined frequency signal is disposed at the mining appara-tus in a shunt circuit with the load components, the filter thereby being connected to the generator.  Circuitry moni-tors the impedance of the electrical load on the generator at the predetermined frequency and a contactor responsive thereto stops the delivery of power from the power supply to the mining apparatus upon the impedance of the electri-cal load on the generator at the predetermined frequency exceeding a predetermined level which exceeds the impedance of the shunt combination of the filter and load compon-ents.  Switching circuitry disconnects the filter from the generator in response to the flow of significant current from one of the conductors to the mining apparatus frame, thereby increasing the impedance of the electrical load on the generator at the predetermined frequency to above the predetermined level, whereby delivery of power from the power supply to the mining apparatus is stopped.
