  • Patent number: 4506514
    Abstract: A system for minimizing the energy consumption in a central air conditioning unit incorporating a refrigeration unit which is normally in operation to supplement or substitute for the cooling effect of outside air. The system employs sensor to sense the enthalpy of the return air entering the unit from the work space, the outside air entering the unit from the outside, and the washer air discharged into the work space from the unit, and controls the operation of the unit in accordance with the relative levels of enthalpy at these points. The energy content of the discharged washer air may be modified by modulating dampers controlling the proportion of outside and recirculated air, and also by modulating the washer which provides evaporative cooling and, in addition, cooling by refrigeration.

  • Patent number: 4353196
    Abstract: This invention relates to a method of automatically forming packages of materials or goods such as milk packages from flexible film and to the novel packages produced thereby. The roll stock film is passed over a forming shoulder to give it a tubular shape and the opposite edges are joined by a sealing bar to form a tubular portion. The milk pouches or other material to be packaged are then dropped into the tubular portion which has previously been laterally sealed across the bottom. The weight of the pouches draws the film down between a pair of reciprocating cutting and sealing jaws when they are opened until the pouches come to rest upon a pivotal support member. The jaws are then closed to form two lateral seals, i.e. one for that package and one for the next package, and a lateral cut separates the packages. The package thus formed may also have an upper handle portion.
