  • Patent number: 4600209
    Abstract: A transport support for securing a free standing transportable accessory having a high center of gravity such as a portable IV stand to a transporting vehicle having a relatively low center of gravity such as a wheeled gurney or wheelchair. The transport support comprises a first member secured to the transporting vehicle and a matingly indentical second member coupled to the transportable accessory, and releasable members for coupling the first and second members together. The releasable members including mating serrated washers for fixing a desired angular relationship between the vehicle and accessory.

  • Patent number: 4368452
    Abstract: An electrical safety connector 10 provides a thermal linkage 12 between two female connectors 11. If a high resistance contact occurs at either connector 11, thermal linkage 12 melts and the molten material, of which thermal linkage 12 was comprised, flows under the influence of gravity to an expansion void 14 in an insulation sheath 13, thus interrupting current flow through connectors 11 and preventing the re-initiation of such current flow. Any potential fire hazard from the localized temperature rise at said high resistance contact is thereby eliminated. An alternate embodiment provides a male pigtail wire 17 for utilizing safety connector 10 in updating the wiring of early wired residences and other structures.
