Abstract: SELF-RAISING BIN LOADING AUGER FOR COMBINES                    ABSTRACT OF THE DISCLOSURE          A loading apparatus for the grain tank or bin of an agricultural combine.  The grain tank or bin is located in the upper part of the combine, and, in the illustrated embodiment, the grain bin comprises a main grain bin and a grain bin exten-sion mounted above the main grain bin.  Clean grain which has been separated from the straw, chaff, or the like, is conveyed by an elevating conveyor which discharges the grain into a relatively short horizontal fixed auger conveyor which is in grain feeding relation to an elongated pivotally mounted "floating" auger conveyor.  The fixed horizontal auger conveyor is positioned contiguous the upper portion of the bin, but spaced below the upper end of the bin extension, and also extends laterally inwardly to the bin from the general region of one longitudinal side of the bin.  A pivotally mounted floating auger conveyor extends from contiguous the laterally inner end of the horizontal auger conveyor and in overlying relation to the hollow interior of the bin and discharges into the bin at a substantially central location. The rotatable shaft of the horizontal auger conveyor is connected in driving relation to the rotatable shaft of the pivoted or floating auger conveyor by a universal drive joint, whereby the auger shaft of the pivotally mounted floating auger conveyor is rotatably driven at any angular position in a vertical plane which the auger tube of the floating auger conveyor may be required to assume about its horizontal pivotal axis.  As the grain level in the grain bin approaches a full condition, the floating auger conveyor moves angularly ` upwardly from a horizontal position due to the reaction of the discharging grain with the upper surface of the already loaded grain, the floating auger conveyor riding on the upper surface of the already loaded grain.  A tension spring may be used to exert an upward force on the floating auger conveyor, supplementing the aforementioned reaction force of the discharging grain.  The use of a floating discharge auger conveyor which rides on the upper surface of the already loaded grain as the grain bin approaches a full condition minimizes grain damage and lowers power requirements as compared to a discharge auger conveyor which might become submerged in the already loaded grain, and also avoids excess height of the combine as compared to a fixed position discharge auger conveyor which is permanently located at the maximum height required, whereas the "floating" discharge auger conveyor only reaches its maximum height when the grain level in the bin reaches its maximum height.

Abstract: Abstract of the Disclosure Switch array has multiple sets of at least opposed pairs of contacts on opposed pairs of parallel flat resilient conductive switch blades arranged side-by-side with corresponding blades supported in generally common planes generally parallel to one another by rigid mechanical engagement of each blade at a position remote from its contact area by an insulating wall of a relatively rigid support frame.  In order to operate, one of the blades of each pair is moved by actuator means engaging its end remote from the point of support on the frame and more proximate to its contact.  The actuator means includes a rigid member rotatably supported on the frame for oscillatory movement about a fixed axis on the frame and providing a slot in the plane of corresponding ones of the blades, which slot is positioned to closely engage the ends of at least some of the blades in that plane.  When the actuator means is rotatably moved about its axis, it moves the engaged blades in a direction transverse to their original plane and their supported contacts toward or away from engagement. Their opposed contacts, preferably resilient means between the frame and the rotatable actuator member, acts to restore the actuator means to predetermined position and means is provided to retain the actuator means in at least one pre-determined position into which it is moved against the restraining force of the resilient means.  Similar actuator means thus defined may be supported on the frame rotatable about a common axis but engage different blades in the same plane to thereby define distinct groups of commonly actuated switches within the array.

Abstract: Abstract A marine exhaust system comprising an exhaust gas-cooling water separation chamber, a gas collection chamber and gas acceleration and gas flow-shaping conduit.      The entrance of the separation chamber is connectable to water coolant and gas exhaust tubes from a marine engine.  The separation chamber is fitted with a water deflector disposed below the gas exit from that chamber, while a gas dam is disposed in the water exit from that chamber, the entrance and water exit being below the deflector level.  Gases from the separation chamber are exhausted through the gas collection chamber, the gas acceleration chamber, and the gas flow-shaping conduit in series to an exhaust outlet.  The conduit com-prises a gas velocity tube which is connected to and extends downstream of the gas acceleration chamber to cause exhaust gases to exit through the hull of the boat in which the syst m may be installed with sufficient force to penetrate the turbulent boundary layer of air developed around the boat hull when the boat is in motion, thus eliminating the tendency of the gases to pass back into the rear of the boat from the "station wagon" effect.  An air dilution tube can be connected to the gas velocity tube to provide a scarfing action by the exhaust gases, causing their dilution to below noxious levels.  The system may include exhaust noise-retarding means, such as a muffler and/or air barrier at the separation chamber entrance.

Abstract: (Case No. 6728) TRACK CIRCUITS WITH CAB SIGNALS FOR DUAL GAGE RAILROADS     ABSTRACT OF THE DISCLOSURE       Alternating current track circuit energy for train detec-tion and cab signals is coupled to the exit end of an insulated, dual gage track section between the common rail and the other two rails connected in parallel.  The track relay is connected at the entrance end in a similar manner.  Impedance bonds for direct current propulsion are also connected between the com-mon rail and the other two rails at each end.  In all forms, the propulsion return current is sufficiently balanced between the three rails to eliminate cab signal interference in either gage.  In a first arrangement, a direct wire connection multi-ples the two other rails at each end,  Impedance bond taps to complete the return circuit provide a two to one turn ratio from the common rail end of the bond winding to equalize the propulsion current ampere turns on each side of the tap and thus balance the flux generated,  In a second form, the short end of the impedance bond has two windings with an equal number of turns but each only one-half of the larger end turns.  Each short end is connected to one of the other rails to again bal-ance the total ampere turns on each side of the winding tap.          In a third form, the other rails are coupled at each end of the section by an L-C circuit path with track circuit energy and the track relay connected between the common rail and the junc-tion between the L and C elements,  A center tapped impedance bond is connected in a conventional manner between the common and narrow gage rails at each end with a resistive impedance path connected between the tap and the broad gage rail.

Abstract: This invention is in the field of material handling equipment and is specifically directed to the field of conveyor belt constructions and methods of fabricating conveyor belts formed of rubber-like material in which longitudinally extending reinforcing tendon members a such as wire cable are provided. Heavy duty conveyor belts such as are used in mines, quarries and the like are usually formed of rubber or similar material (hereinafter referred to as "rubber-like material") with the rubber-like material being provided with embedded reinforcing members in the form of steel cables or wires for achieving the necessary strength for the particular usage to which the belts are to be employed.  It has been conventional practice for many years to embed such cables in the rubber-like body of the belt during the fabrication of the belt member. Prior known conveyor belts of the aforementioned type can be several thousand feet in length and are consequently extremely heavy so that it is necessary that the belts are assembled at the conveyor installation site with completed belt sections each consisting of a cured rubber-like belt material in which the embedded tendon members are provided.  It has been the previous practice to fabricate from which the cured ready-to-use belt sections are transported to the assembly site and spliced together in end-to-end manner until the complete belt loop formed of the discrete sections is fabricated.  The great weight of the conveyor belt material limits the length of each belt section and creates substantial problems of transportation particularly where the belt is to be assembled in remote areas.
