Title: Collapsible table formed of injection-molded half-sections
Inventor: SAGOL SAMI
IPC: B29C45/33
Filed: 2002-12-10
Abstract: A system for injection molding a half-section of a collapsible table that includes a pair of interhinged half-sections. The system is provided with a mold whose dimensions are appropriate to the half-section to be molded therein, and a driven carrier adjacent one end of the mold having cantilevered therefrom parallel core rods that project into the mold. When the carrier is driven to cause the core rods to occupy an "in" position in which the rods are fully within the mold and extend the full length thereof, molten plastic is then injected into the mold to submerge the rods therein. When the plastic cures and rigidifies, parallel reinforcing beams are then created about the rods which are integrated with the resultant half-section. When the carrier is driven to withdraw the rods from the mold which are now in an "out" position, the reinforcing beams are then hollow and the resistance of the half-section to bending forces is enhanced.

Title: Adapting a document repository to support fine-grained change requests, lightweight transactions and asynchronous notifications
Inventor: SEELEMANN ALEXANDER D II
IPC: G06F17/30
Filed: 2002-12-20
Abstract: A repository adapter, repository adapter client and methods provide enhanced collaborative authoring of documents stored on a repository. Repository adapter clients access the repository using the repository adapter that is adapted to communicate with the clients using a bi-directional asynchronous protocol. The repository adapter communicates with the repository in accordance with a repository protocol such as the WebDAV protocol. The repository adapter performs change requests on behalf of clients in a transactional manner, in communication with the repository. Serialization of requests by clients and transactional processing by the shared repository adapter serves to reduce resource contention otherwise experienced by collaborative authors in a conventional WebDAV environment. Fine grain changes to objects, relationships and attributes may be made using the repository adapter. Further the repository adapter asynchronously updates clients when the document model is changed, freeing the co_laborative author from determining whether documents must be refreshed and obviating pre-emptive locks.

Inventor: HORSLEY PETER BROWN
IPC: B64G1/40
Filed: 2003-02-13
Abstract: This invention relates to propulsion systems for driving a space vehicle.  The main element of the propulsion system is an elongated hollow tube that is open at one end and closed at the other end. Inside near the closed end there is a jet engine, a heater for raising the temperature of a gas, a gaseous substance, a gas compressor and a means of generating a directional force. The said force is directed towards the closed end of the tube. The means adapted to provide the said force may be electrostatic force, or it may be centrifugal force generated by spinning the whole unit. The said force causes the gas to collect at the closed end of the tube. The gas is first compressed and then heated to a high temperature in a container. Then the hot high-pressure gas is introduced to the jet engine, which directs the exhaust gas towards the open end of the tube. Two extra forces result, the main one being the push from the jet engine. The other force derives from the cooling gases circulating down the walls of the tube to the closed end of the tube, where a change in the direction of momentum causes an additional force. both extra forces are directed towards the closed end of the tube. There are no opposing forces because the other end of the tube is open to space.
