In one exemplar embodiment, a valve seat puller is disclosed utilizing a plurality of J-shaped hooks mounted for limited pivotal movement on a hook support block. The hook support block and J-shaped hooks are supported by a threaded rod extending through a central aperture in the support block and secured in place by a lock nut. The J-shaped ends of the hooks are spread to engage the lower rim of the valve seat. The threaded rod passes through an aperture in a pump support plate spaced above the...

This invention provides a method for repair for poles which have beem damaged by environmental effects, which is easily transportable, simple to install, and easily adaptable to many classes of poles. The method involves excavating around the pole, cleaning the surface of the pole, pumping a fumigant into the pole, applying a bonding agent to the clean surface, and then applying strips of a composite fiberglass mat and resin to the pole in a controlled manner until a desired casement thickness h...

An integral floating cooler structure including a barge member having a barge bottom and barge sides with a storage chest having a chest bottom formed in common with the barge bottom, and chest sides of less thickness that the barge sides and having lower portions formed in common with the barge sides. The chest bottom and said chest sides are of thickness sufficient to provide thermal insulation. The barge bottom and the barge sides are displacement volume sufficient to provide buoyancy for the...

The apparatus includes a truck body having a forward cab section and a rear bed section, the bed section adapted to further provide a plurality of horizontal members, comprising a truck bed, the members positioned atop a rear axle for defining a bed portion for accommodating a boat thereupon. There is further included a rear section of the bed portion hingedly engaged to the rear portion of the frame which is movable from a horizontal position to form the rear portion of the bed to a position so...

A toy adapted to instruct young children by association. The toy teaches proper numeric, alphabetic, or color sequences and the standard left to right reading convention, by utilizing blocks that are inserted into shafts in a stand. Blocks inserted out of proper sequence will fall through the stand but passage of blocks inserted in the proper sequence will be obstructed and those blocks will not fall through but will remain supported within the stand.

A pumping system for sludge including hazardous waste material and other viscous material includes a vacuum pump for drawing sludge into and through an intake line to a separator where the heavier components of the sludge descend into a closed tank hopper. A positive displacement pump discharges the sludge from the closed tank hopper through a delivery line to a remote point of disposal or storage. A centrifugal pump attached to the sludge receiving end of the intake line and being hydraulically...

A temporary road is provided which includes a plurality of sets each defined by a first and second matrices which include an upper surface for supporting heavy vehicles and the like over rough or impassable terrain and a second matrices which comprises support members for the upper or first matrices. Thus, one set is laid down such that the first matrices is in a top or upper position and cross members of the second matrices support the top member or upper matrices and thereafter a second set is...

A demountable exercise apparatus for installation in conventional doorways comprises a pair of parallel rectangular support members each formed of separable sections. Each support member has a plurality of longitudinally spaced polygonal recesses, in opposed relation, which receive the rectangular extensible ends of a horizontal exercise cross bar. The recesses are also adapted to receive the ends of an expandable chinning bar. The cross bar height is vertically adjustable by positioning in sele...

A high pressure seal structure to seal against fluid pressure around a cylinder member movably. The structure includes an integral circular metal sealing ring including a pair of first circular sealing lips having a cross-section of chevron shape axially opening in a first direction to flexibly extend with a first inner lip in sealing relation against the cylindrical surface of the cylinder member and with the first outer lip in sealing relation against a cylindrical wall formed in the housing. ...

This invention relates to a method and apparatus for diluting and activating a polymer in water. More particularly, the invention relates to the use of a stirred tank in conjunction with an aging tank that allows the polymer to uncoil or become activated in water after dilution, but prior to introduction into service.
