  • Patent number: 6171016
    Abstract: A tubular reinforcing dowel system includes a plurality of fiber composite hollow, tubular dowel tubes comprising a first material and each including a longitudinally-extending bore. The dowel tube bores are filled with a second material, such as hydraulic cement, to form dowel members. The dowel members are mounted on a basket assembly which includes a pair of horizontal runners and multiple, longitudinally-aligned pairs of stands mounted on the runners. Each stand is connected to a respective dowel member end. A reinforcing method includes the steps of mounting multiple reinforcing dowel members on a basket assembly, placing the basket assembly on a crushed rock base of a roadway and pouring a cement slab on top of the base and encasing the dowel members underneath a transverse construction joint.

  • Patent number: 4631970
    Abstract: A pumping unit for pumping fluids from a location beneath the surface of a field. The rotary motion of a crankarm is changed to a reciprocating motion of a pair of flexible members by pitman arms pivotally secured at one end to the crankarm and at the other end to the flexible members which extend from such connection over a plurality of rollers and then vertically downward toward the well head. The flexible members are connected at their other ends to means connected to the polished rod. Portions of the flexible members and the polished rod lie in the same vertical plane so that true vertical reciprocating movement is imparted to the polished rod. The flexible members comprise non-metallic straps having a substantial width to provide stability of movement.
