Title: Material handling and sorting system
Inventor: REX MICHAEL PAUL
IPC: B61L27/04
Filed: 1982-08-23
Abstract: Mechanised mail sorting offices require packets to be sorted according to destination into one of many bags. A typical mechanised system includes a loading mechanism for transferring packets from stationary input pockets onto a continuously moving sequence of containers which pass all destinations in turn and unload as required. The system according to the invention consists of a number of separate self powered single trolleys (TL) which run on a tracking network. Each trolley (TL) is adapted to be programmed with the route to be taken to the destination of the packet(s) loaded into it. The trolley (TL) co-operates with en-route track-side signposts (TSB) enabling steering means (SM) in the form of a guide arm at the front of the trolley (TL) to guide the trolley around the tracking network to and from its required destination for unloading its package into a bag. Programming is done by operators at induction stations (ISA, ISB, ISC and ISD) at sidings in the tracking network while the trolleys are stationary.

Date Aug. 24, 1995An ultrapure egg oil is prepared starting from dried and powdered avian or reptilian egg yolk by means of extraction with the aid of fat solvents, followed by two-step ageing, first at ambient temperature and then at a lowered temperature, separating off and centrifuging off the less viscous phase formed and again separating off the less viscous component. This component is, if appropriate repeatedly, mixed with demineralized water and heated, and, after cooling, the less viscous phase is separated off and again centrifuged, the less viscous component is again separated off and held at a lower temperature, the phases are again separated, and the less viscous component which has been separated off is recentrifuged. This again results in phase separation, the less viscous component which has been separated off being the end product which is a yellow to reddish, fluid oil which can be stored without preservatives. The ultrapure egg oil prepared by this process can be used for the treatment of skin burns, including sunburn, and for regenerating the skin in cosmetic products.

Title: Method and apparatus for increasing the efficiency of transactions and connection sharing in an enterprise environment
Inventor: JEYARAMAN THULASIRAMAN
IPC: G06Q10/06
Filed: 2001-09-05
Granted: 2005-04-13
Abstract: Methods and apparatus for improving the overall performance of a system which processes transactions and provides connections in an enterprise environment are disclosed. According to one aspect of the present invention, a method for processing a transaction in an enterprise environment includes receiving a request to start the transaction, storing information which indicates that the request to start the transaction was received, and accessing a first resource manager associated with the transaction. Typically, a container receives the request to start a transaction from a component such as an enterprise bean. Once the first resource is accessed, the transaction is initiated as a local transaction on the first resource manager, and, eventually, the transaction is completed. In one embodiment, completing the transaction includes using a local transaction mechanism of the first resource manager to complete the local transaction.
