Abstract: A device for the protection of camera lens and the fixation of cameras, the device is a screw up bolt, its special feature lies in the screw-up-bolt being a round stub, the inner dimension of the bolt is to connect with the outer bottom of the camera with a matching thread or bolt flute. It could screw up with the bolt stub with inner screw thread, and to match up in accordance with the sizes of camera lens in varied screw threads of different designs by various manufacturers. The device could screw up with the bolt at both ends to connect with camera lens, therefore, it could connect two camera lens at the same time.

Abstract: A method and apparatus of applying a particulate material to a substrate includes applying adhesive to the substrate and passing the substrate through a chamber in which a particulate material is suspended in a fluid in order to adhere the particulate material to the substrate.

Abstract: A method and system for applying an adhesive/superabsorbent mixture to a substrate, the method and system being adapted for heating an adhesive and superabsorbent polymer mixture to a first temperature at a first pressure, the first temperature being less than the boiling temperature of said mixture at the first pressure; heating the mixture through a heat exchanger at a second pressure, the second pressure being higher than the first pressure, the heat exchanger being adapted to raise the temperature of the mixture to a second temperature that is higher than the first temperature; and selectively applying the mixture to a substrate.

Abstract: An apparatus and process for preparing activated carbon from a wood or wood residue feedstock using fluidized bed technology. The fluidized bed apparatus has a number of wood residue inlets that allow differing residence times in the fluidized bed apparatus appropriate for the wood or wood residue feedstock to be carbonized. The carbonized material may then be activated to form activated carbon.

Abstract: A method and apparatus is provided for forming and attaching tabs to an absorbent article worn in the perineal portion of the body, such as sanitary napkins. A strip of tab material is cut into two tab strips by making an approximately sinusoidal shaped longitudinal cut using a rotary die. The tab strips are then inverted so the tabs face outward and aligned so that the tabs are in-line. The tab strips are then cut into tab pairs and attached to a strip of absorbent article using an adhesive. In an alternate embodiment, the tab pairs are first attached to a layer of material which is then attached to a second layer of material on which an absorbent core is disposed, thereby enclosing the absorbent core. An absorbent article made by the aforementioned method and apparatus is also provided.

Abstract: Apparatus and methods for forming improved airlaid fibrous articles are disclosed. Airlaying apparatus is provided which permits at least two types of fibrous materials to be defiberized and transported to a single airlaying apparatus. In a most preferred embodiment, a drum-type airlaying drum having a plurality of deposition cavities is provided. By controlling the airflow and pressure differential, selective placement of each type of fibrous material within a cavity is achieved. Also disclosed are improved deposition cavities which permit multiple materials to be airlaid and retained in position by providing a foraminous surface on at least a portion of the cavity sidewall. Most preferably, a hydrophobic fiber layer is formed and a layer of absorbent fiber is deposited within the first layer; the present invention permits a clear demarcation between the fiber types. Also disclosed is improved apparatus for removing airlaid articles from deposition cavities, using a precisely controlled airstream.
