Abstract: An information sharing method and apparatus using an object oriented technology are provided for mutually sharing any manipulation events in a shared environment which operates in a plurality of computers on a network. The method provides a plurality of objects to be used by users for information processing on their information processing apparatuses, and an environment in which the objects operate. Each of the objects transmits an event made thereto by an operator as a message. A shared field object is shared by a plurality of users, and one or more objects operate on the shared field object. These objects are distributed to the plurality of users to share the same environment among the users. A message of the event is distributed to each of the users through the shared field object to recall the event in the respective environments to share the operation of the object.

Abstract: A multi-layered hose comprising, in cross section, a) a plurality of layers defining b) a channel, said hose having a density less than that of water at the same temperature. The hose is particularly suitable for use in connection with substantially nonvolatile fluid transfer, for example pool cleaning and the like since it is capable of floating on a water surface.

Abstract: A two-compartment container has a lid portion and a base portion hingedly connected to one another and openable and closable in the manner of a clamshell. Both the lid portion and the base portion have partitions, which extend from the hinge and which are aligned with one another. When the container is closed, the partitions abut against one another, effectively isolating the two compartments formed in the base portion by its partition from one another. The base portion includes a locking flap which fits into a gap between the partition in the lid portion and its face and seals it to further isolate the two compartments from one another.

Abstract: A packaging container is integrally formed from plastic foam material, such as extruded polystyrene foam. The packaging container has a base, four sidewalls extending from the base, and four corners, each extending between a pair of adjacent sidewalls. The sidewalls have substantially rectangular protrusions extending from the base to a top edge to strengthen the sidewalls against lateral forces. The sidewalls may also have rounded ribs which protrude into the interior of the packaging container for further reinforcement.

Abstract: A packing tray is provided for use in both cell pack and tray pack arrangements. The packing tray is unitarily formed from polystyrene foam to have a cellular structure. Cells are arranged in longitudinal rows of alternating odd and even numbers, and the cells are partially separated by cell dividers, which have at least major portions recessed within the tray.

Abstract: A method and apparatus for forming plastic articles is provided. A rotating cutter, having a cutting blade mounted thereto, is disposed adjacent to a continuous extrudate. Upon rotation of the cutter, non-linear cutting edges formed on the cutting blade simultaneously cause a predetermined length of the extrudate to be severed and formed. The method and apparatus are well-suited for forming plastic articles having an elongated shape with rounded ends.

Abstract: A food serving tray, preferably of polystyrene foam, is provided having a base and bounding side walls. The base is formed with at least two bottom walls and at least one partition interposed therebetween. To provide enhanced stability and rigidity to the tray, protrusions, preferably step-shaped, are formed in the side walls located between the crests of the partitions and the top edges of the side walls. The protrusions provide changes in direction in the side walls which enhance the strength and rigidity of the tray. In addition, the bottom walls may be dished concavely so as to have portions extend upwardly. Under loading, the dished bottom walls become flattened and bi-axially stressed to further enhance the overall strength and stability of the tray.

Abstract: An egg carton is provided having various nesting/denesting features, a ventilation system, reinforced portions, and capability of accommodating and protecting various sized eggs. The nesting/denesting features include thickened corners on the lid, an indented post and a stacking ledge on the tray, each feature reducing the amount of surface contact between nesting components and facilitating denesting. The ventilation system includes channels formed in the cells of the tray and a vent which enables effective natural and artificial cooling of packaged eggs. The reinforced portions include embossments being formed on the bases of each of the cells, along with compacted raised portions. Finally, the cells are provided with high flexible walls for protecting the eggs and deflectable cushions shaped and located to securely hold eggs which are smaller than the natural size of the cells.

Abstract: A processor tray is provide for maintaining plastic film wrapped thereabout in a taut state. The tray is unitarially formed with a plurality of sidewalls, a comer joining each pair of sidewalls, and a base. A flange is formed to extend outwardly and downwardly from uppermost portions of the sidewalls and the corners preferably in the range of 15.degree.-35.degree.. Additionally, the flange may be formed with varying widths about the perimeter of the tray. The base may be either formed flat or, alternatively, the base may be formed with three concentric regions to define a concavity, with one region being planar and raised relative to the bottom of the tray.

Abstract: A bowl cover assembly having a configuration which provides for secure interlocking between the bowl and cover with at least one opening for venting purposes along the rim of the cover when the cover is locked onto the bowl.
