Abstract: A system includes a containment vessel configured to receive and retain equipment to be decontaminated. The system also includes a solar reflector configured to reflect solar energy towards the containment vessel in order to heat the containment vessel. The system further includes end supports configured to receive and retain the solar reflector and the containment vessel. The system also includes a base having or coupled to multiple side supports, where each side support is configured to contact and support a corresponding one of the end supports. In addition, the system includes one or more semi-transparent solar shades configured to reduce the solar energy reaching the solar reflector and the containment vessel.

Abstract: A folding scaffold sign. The sign is constructed of a special honeycombed plastic material in which two sign panels are provided, separated by a fold line. The bottom corners of the panels are provided with metal legs inserted through openings forming the honeycomb structure. The legs are retained in the openings by elasticity and friction of the plastic memory material and the sign can be used as a triangular free-standing sign supported upon a floor surface, ground or the like. The sign may further be used as a cover for an existing conventional post-supported sign by placing the folded sign thereover and folding the panels together and retaining the legs in secured condition by a retaining chain. The folded-over sign may be stored in the same presentation when the panels are folded over against one another in superimposed position.

Abstract: A thermally responsive valve is connected to a fire extinguisher between a pressure gauge and an extinguisher outlet to which such gauge would normally be secured. The valve includes a fitting having a passage extending therethrough so that pressure in the extinguisher may be sensed and displayed by the gauge. Detachably mounted to the fitting is a spray head having a port communicating with the passage, the port being normally sealed by a heat collecting disc. The disc is fused to the spray head by fusible material and when the environment surrounding the extinguisher reaches a predetermined temperature, the fusible material will melt thereby releasing the disc from sealing the port. The extinguisher's pressurized contents are then automatically expelled through the port for extinguishing a fire.

Abstract: A combination air conditioning and fire protection system for a building including a heat exchanger through which fluid may pass under pressure, a fluid conditioning unit operable to bring fluid to a desired temperature for passing through the heat exchanger, and fluid supply and return conduits interconnecting the heat exchanger and fluid conditioning unit for circulating fluid therebetween. The supply and return conduits have discharge heads spaced therealong which are openable in case of fire to discharge fluid therefrom to extinguish a fire in the vicinity of the head. The conduits may include risers in the form of hollow, fluid-tight structural columns which also act to provide structural support for the building. Flow control devices and check valves in the system assure that pressure will be maintained in either the supply or return conduits to discharge fluid onto a fire if the other conduit is damaged and loses pressure.
