Abstract: A collapsible support frame has a top opening and open sides to allow a plastic bag to be received through the top opening. Anchoring members protrude outwardly from the frame to engage the top of the open bag after it is folded over the frame. The anchoring members are dimensioned to at least partially stretch the folded-over portion of the bag to insure that the bag remains secured to the frame even when the bag is weighed down with materials placed in the bag, such as trash, recyclables, etc. After the bag is full and is to be removed from the frame the folded over portion is manually urged over the anchoring members to separate the bag from the frame. While the bag is held in the frame the exterior surfaces of the bag are visible and preferably bear messages, advertisements, etc.

Abstract: A flat article carrying case includes corrugated sheet material which substantially wraps about the entire case with the exception of the lateral sides of the case. A handle is attached to the front side of the carrying case. Two frame members, forming the lateral sides of the carrying case, are provided for providing stiffness and rigidity to the case, when covered with corrugated sheet material which is flexible along a direction parallel to the frame members but substantially rigid or stiff in the transverse direction extending between the frame members. However, it will be evident that different covering sheet materials may be used, in which case different numbers of frame members may be needed to provide requisite stiffness or rigidity to the resulting carrying case.

Abstract: A method and system are disclosed which may be utilized to generate a simultaneous presentation within a data processing system of video data within multiple windows supported by different graphic user interfaces. Each graphic user interface is coupled to a separate display device driver. Window movements including: creation; deletion; resizing; movement; minimization; maximization; activation; enablement; or an alteration in relative background/foreground order are detected for each graphic user interface and that information and the associated display device driver for each graphic user interface are coupled to a virtual device driver which facilitates interprocess communication between two or more graphic user interfaces, wherein the portion of the video display which is managed by each graphic user interface may be ascertained.

Abstract: A knockdown portable shelter includes two spaced supports each formed of elongated members that can be separated from each other at couplings securing the elongated members to each other. The elongate members include leg portions and a roof portion. A sheet like covering material extends between the roof portion of the spaced supports and at least parts of the leg portions. The covering material is substantially more pliable along the direction extending between the two spaced supports than along a perpendicular direction. Hinges allow folding of the material along lines extending between corresponding couplings. Disconnection of elongate members at the couplings allows the covering material to be folded along the hinges and rolled up along the direction extending between the supports. One example of a suitable covering material is single face corrugated hollow core material. The elongate members are preferably hollow plastic tubes and the couplings are hollow plastic elbows made of PVC.
