  • Patent number: 4849076
    Abstract: A method for oxidizing a substrate which is oxidizable by singlet oxygen is discolded. The first step of the method comprises establishing a flow to and from each of a plurality of successive closed zones, each of which zones(a) contains a quantity of a polymer-bound photosensitizing catalyst that is a source for singlet oxygen when irradiated by light of a particular wavelength, and(b) is of such size and shape that a major portion of the catalyst therein can be made a source for singlet oxygen by irradiation with light of a suitable wavelength.The flow is established by charging the substrate in the liquid phase into the first zone, removing reaction product from the last zone, and transferring reaction product from the first zone and from each intermediate zone to the next succeeding zone. Oxygen is introduced into each of the zones and each is irradiated with light of a frequency which causes the catalyst to be a source for singlet oxygen.

  • Patent number: 4807747
    Abstract: A package structure is disclosed. The structure comprises a lid and a base, both of a flexible material which is relatively reistant to elongation and compression. The lid and the base are movable relative to one another between an open position and a closed position. The lid has a central, substantially planar lid panel, and lid channel means which is integral with, and extends about a major portion of the periphery of, the lid panel. The base has a generally flat base panel, and a stepped base wall which is integral with, and extends completely around the periphery of, the base panel. When the lid and the base are in a closed position, the channel means and the step of the stepped base wall abut one another. The structure also includes a base insert adjacent the base panel, interior of said stepped wall. The insert is sufficiently stiff and extends into sufficiently close proximity with opposed portions of the base that it is operable to strengthen the base against flexing.

  • Patent number: 4738392
    Abstract: A mailbox provided with a first signal flag mounted for rotation between a first position indicating the presence of mail in the box to be picked up by the mail carrier and a second, neutral position is disclosed. A flange depending from the first signal flag is adapted to frictionally engage a portion of the mailbox door when the first signal flag is in the first position thereby retaining the first signal flag in the first position. When the mailbox door is opened, for example, by a mail carrier, the frictional engagement is broken and gravity causes the first signal flag to rotate to the second, neutral position. The mailbox is provided with a second signal flag mounted for rotation between a first position indicating that a mail carrier has opened the mailbox door to insert mail and a second, neutral position.

  • Patent number: 4723417
    Abstract: Apparatus for dehumidifying air is disclosed. The apparatus comprises first and second dehumidifiers, both of which employ a desiccant. Air to be dehumidified is passed through the first dehumdifier, then through the second dehumidifer, and from the second dehumidifier to a space to be conditioned. The desiccants of the two dehumidifiers remove moisture from the air so that it is dehumidified before it reaches the space. The apparatus also includes a first regenerator for the desiccant of the first dehumidifier, and a second regenerator for the desiccant of the second dehumidifier. Air is passed to and through each of the regenerators in contact with the desiccant therein and is then discharged. Heat of sorption is transferred from the two dehumidifiers, and moisture laden desiccant is moved from each of the dehumidifiers to its regenerator; finally, heat is transferred to each of the regenerators, and the heat transferred to the first regenerator includes heat of sorption from the first dehumidifier.
