  • Patent number: 4411581
    Abstract: Auger-hopper constructions for mounting to an inclinable body of a truck at the tailgate of the truck includes a pair of hoppers, one of which is stationarily and removably mounted to the truck, and the second of which is pivotally mounted to the first hopper adjacent an opening in the bottom of the first hopper. The second hopper also includes an opening adjacent its bottom at which an auger tube is swivelly mounted. The auger tube, by virtue of the pivotal and swivel mountings, is pivotable in a arc in a plane perpendicular to the axis of the pivotal movement and is swivelable in a arc in a plane which is parallel to the axis of the pivotal movement. Both the first and second hopper are dimensioned and positioned such that no portion of either of the hoppers extends substantially beneath a plane defined by the bottom of the inclinable body of the truck.

  • Patent number: 4388426
    Abstract: Adhesives and coatings, especially two-component epoxy laminating adhesives, are prepared so as to be flame-resistant in the so-called part B or polyamide component thereof by including in that component a chlorinated hydrocarbon solvent together with an adduct of a polyamide and an aromatic hydroxy or epoxy compound. By this approach, the amine is tied up and is rendered resistant to premature reaction with the chlorinated hydrocarbon solvent within the part B component, which premature reaction would lead to the formation of undesirable crystals within the part B component and reduce its pot life. When the part B component is blended with an epoxy-containing part B component, the polyamine adduct gradually disassociates in order to free the polyamine to catalyze setting of the two-component system, particularly the epoxy resin of the part A component.

  • Patent number: 4380091
    Abstract: Circuitry for automatically controlling the water level of swimming pools with a multi-level detecting sensor for directly sensing the pool water. A low voltage oscillator in the input portion of the circuitry detects the presence of water above or below each level sensing electrical contact of the sensor by a change in oscillator amplitude in response to impedance from the contact to ground. Signal threshold circuitry changes in output signal in response to the amplitude of the oscillator signal. Delay circuitry integrates the output of the threshold signal to avoid responding to spurious changes in water level, such as wave action in the pool. Monitor circuitry disposed between the delay circuitry and the water fill, water dump, and pump control circuitry monitors signals received from the sensor or generated by the input circuitry to detect any malfunctions in the sensor or the control circuitry, such as improper sequence of the water level signals, to disable further filling of the pool.

  • Patent number: 4373841
    Abstract: Cargo carried on freight cars such as flat bed railway cars is secured in place by lading strapping that is tensioned around the cargo so as to compress a snubber unit of an integral, telescoping quick-release device that includes a sleeve slidably mounted in a housing secured directly to the side of the freight car, which sleeve is locked in a collapsed condition within the housing and unlocked to move between the collapsed condition and a telescoping condition, the sleeve having therewithin an anchor rod that telescopes from the sleeve in opposition to bias provided by the snubber unit. Unlocking of the quick-release device substantially reduces tension within the lading strapping before it is removed from the cargo.

  • Patent number: 4372442
    Abstract: A torque-transmitting drive having a driving member and a driven member spaced therefrom with an endless transmission belt engaging the members to transmit torque from the driving member to the driven member. The endless belt is folded over one of these members such that two strands of this belt pass over the one member and this same one member thereby does not pass through the endless belt. A bearing sleeve is further slippingly mounted on this one member, over which the endless belt folds such that one strand of the belt at the fold passes over the bearing sleeve. Thus, one strand at the belt fold is in driving engagement with the member and the other strand of the endless belt moves in the opposite direction such that the bearing sleeve is rotating in a direction opposite to that of the member over which the belt folds. When replacing belts, it is not necessary to disturb or dismantle the member over which the endless belt folds, as that member does not pass through the belt.
