  • Patent number: 4784201
    Abstract: A non-pneumatic tire with an annular body of resilient elastomeric material and an outer cylindrical member supported by circumferentially spaced-apart ribs, is provided with four vibration-reducing features. First, the tire has an outer tread surface with a crown radius. Secondly, the tread has a pattern with a plurality of circumferential grooves and lateral grooves arranged to reduce uneven contact pressures caused by radial forces carried by the tire's ribs. Thirdly, the spacing of the ribs is randomly varied around the circumference of the tire to broaden a vibration spectrum caused by the ribs and reduce peak vibrations. Fourthly, a wheel rim that supports the annular body is provided with a structurally incorporated hoop to reduce deflection of the wheel rim during tire operation.

  • Patent number: 4750780
    Abstract: A motor vehicle front body structure including a dash panel separating the engine compartment from the passenger compartment. The dash panel has an upper portion which is inclined forward at an transversely intermediate portion and rearward at the transversely opposite end portions so that the upper edge portion of the dash panel has a forwardly convex configuration to conform with a corresponding configuration of the lower edge of the windshield glass.

  • Patent number: 4739810
    Abstract: A non-pneumatic convoluted cone wheel having a hub section and a resilient section that has a ground-engaging rim at its peripheral outer edge portion to which a tire tread can be provided for the ground engaging rim including an internal element to vary the rate of the wheel with deformation under load which is turnable for changing stiffness with deformation of the resilient section.

  • Patent number: 4671550
    Abstract: Disclosed is a bumper beam formed of a plurality of elongate sections. The sections are formed of composite material comprising both longitudinal fibers and random fibers embedded within a resin matrix. The longitudinal fibers extend continuously between the opposing ends of the bumper beam with their longitudinal axes being substantially parallel to the longitudinal axis of the beam. The random fibers have their longitudinal axes randomly oriented with respect to the longitudinal axis of the beam. The longitudinal fibers comprise 70-85% of the total weight of the longitudinal and random fibers. The cross-sectional shapes of the sections are such that when subjected to the stresses induced by a collision, the outermost sections will tend to deflect in the lateral direction.

  • Patent number: 4441633
    Abstract: A manually operable trigger pump has a pump body, a circular cap disposed below the body and adapted to engage a container having material to be pumped out, a generally vertical trigger pivotally coupled at its upper end to the body and a linkage coupled at one end to the trigger intermediate its ends and extending from the coupled end into the body. The trigger has a surface adjacent the body. The surface has a longitudinally extending groove therein. A locking device is detachably securable to and is manually rotatable about the cap. A generally horizontal arm integral at one end with the device extends radially outward from the cap. The other end of the arm has a tip which is engagable with and disengagable from the trigger surface groove. The device is rotatable to a locked position at which the tip engages the groove. At this point, when the trigger is squeezed, the movement of the trigger is insufficient to actuate the pump.

  • Patent number: 4395921
    Abstract: An adjustable volume dispenser comprises a barrel assembly having an internally threaded tubular portion, an adjustable stop formed with external threads engaged with the internal threaded tubular portion of said assembly, and a sleeve coaxially mounted within the tubular portion and rotatable therein, said sleeve being connected to the adjustable stop for imparting rotation thereto but allowing said stop to move axially thereon. A finger engageable wheel connects to the sleeve for rotating the adjustable stop relative to the barrel assembly, a plurality of numbered wheels being coaxially connected to the finger engageable wheel for indicating the position of the stop and the volume of liquid to be dispensed. A plunger assembly is provided including a rod reciprocally removeable within the barrel assembly, said rod extending coaxially through the adjustable stop, the sleeve and said wheels.

  • Patent number: 4396133
    Abstract: A wax cylinder for a wax spraying machine is disclosed. The wax cylinder includes a housing, an ejection cylinder having a chamber mounted in the housing. An elongated piston is slidably mounted in the chamber and includes a pressure face for pressurizing and urging wax in the chamber out through an ejection opening. The chamber is maintained in constant fluid communication with a feed line for feeding wax into the chamber throughout the stroke of the piston. A check valve is utilized to prevent back flow of wax through the feed line. Air is prevented from flowing into the chamber during the return stroke of the piston.

  • Patent number: 4392554
    Abstract: This invention relates to an improved visibility free lift mast (10) which eliminates the problems of reduced lift height, upright strength and excessive guide bearing loading. The lift mast assembly (10) has a fixed upright (42) and a movable upright (52) mounted on the fixed upright and elevationally movable relative thereto. A lower guide bearing (80) is mounted on a lower end portion (78) of the movable upright (52) and an upper (88) and intermediate (98) guide bearing is mounted on an upper end portion (92) of the fixed upright (42). The intermediate guide bearing (98) is positioned between the upper and lower guide bearings (88,80) a preselected distance (D) spaced from the upper guide bearing (88).
