  • Patent number: 5234533
    Abstract: A portable hot sir sheet welder used for making reservoir liners and covers. The welder is sued to fuse together overlapped edges of lengthy sheets of synthetic rubber material or the like. The welder has a front carriage and a rear carriage both of which have a weight box for removably receiving cast ingot weights. The front carriage has a pair of laterally spaced main drive compression wheels for pressing the overlapped sheets together after they have had their surfaces heated to a sufficiently high temperature by a hot air shoe pounded on the front carriage. A pair of laterally spaced secondary compression wheels are supported from the front end of the rear carriage. An eccentric mechanism attached to the rear carriage provides structure for pivoting the main drive compression wheels upwardly from their pressure producing position.

  • Patent number: 5108225
    Abstract: An elevated wall reservoir system that has a floating cover assembly that lies directly on the top surface of the body of liquid. The peripheral edges of the cover assembly extend beyond the edge of the liquid and are resiliently secured by tension cables that are attached to tension towers. The tension cables hold the cover assembly in position on the top surface of the liquid and permit the cover assembly to travel upwardly or downwardly in response to the liquid level. Thus the cover assembly is always supported by the liquid and tension in the tension cables. The elevated wall reservoir system allows existing reservoirs to be modified to increase their storage volume by twenty or fourty percent without the need of utilizing additional land area. The elevated wall reservoir system can also be used on new installations.
