  • Patent number: 5046329
    Abstract: Two versions of a portable air conditioning unit (10, 100) are provided. The larger unit (10) is separable into two halves (12, 14) which contain three cold objects (32, 34, 36) such as freezable gels. A series of aluminum baffles (22-30) define a torturous air flow passage through the unit where air passes over each one of the cold objects sequentially to significantly cool the air flow through the unit. The air flow is generated by a fan (38) which can be powered by batteries, AC power, solar power or the like. The second embodiment of the air conditioning unit (100) can be actually carried by the user with a strap to cool the face of the user.

  • Patent number: 3980196
    Abstract: A pair of flexible, load distributing, front cross members, a rear frame, and a rear bulkhead mounted on the rear frame, mount and securely retain a flexible bag as a liner within a freight container, truck trailer or the like, to adapt the container for bulk cargo transport. The front cross members retain the front end of the liner bag in generally rectangular configuration and are secured at opposite ends to structural members of the container, thus supporting the front end of the bag against displacement and possible damage or rupture, and transmitting the bag forces to the structural members. The rear frame and a curved bulkhead mounted thereon support the rear end of the bag and similarly prevent its rupture or collapse during loading and tilt-unloading. The laterally curved rear bulkhead also acts as a funnel to completely evacuate the bag contents during tilt-unloading through an opening therethrough.
