Abstract: The computer-implemented method of determining the intersection in space and time between an entity and an event comprises inputting, at an event computer, event data to be stored in an event database. The event data comprises event identification data, finite or infinite event duration data representing an event duration, and event geographical location data representing geographical locations, the event geographical location data being defined over time during the event duration. The method also comprises obtaining, at a server, entity data that comprises entity identification data, finite or infinite entity duration data representing an entity duration, and entity geographical location data representing a geographical location, the entity geographical data being defined over time during the entity duration.

Abstract: The present invention provides a tool being used to crimp a ring onto a pipe joint, which includes two half-die members having each bore openings and a recess formed at their rear end portion for receiving a body member to be connected therewith by dowell pins, and further at their front end portion is formed a recess for receiving a threaded rod coupled to a clamp bolt. The threaded rod is engaged therein a threaded bore formed thereon a bushing passing through two bores located thereof each side of the lower half-die member. The clamp bolt is blocked therein the bushing by a spring pin to be engaged therethrough a hole formed therewith and through a hole formed therein the threaded rod. Further, the both half-die members are disposed in alignment with the bore openings for receiving the ring that is crimped onto the pipe joint by the use of a handle having at each end portion a notch to prevent the handle to be pulled out of the clamp bolt.

Abstract: A cooking appliance, such as a gas grill, includes a cooking pit, at least one radiant gas burner on a side wall of the pit, a receptacle for collecting liquid and cooking juices, and a bottom assembly which is heat-retaining and permeable with respect to the liquids flowing toward the collecting receptacle. The cooking appliance further includes a water spray assembly which allows steam cooking.

Abstract: A heating apparatus has a catalytic burner and a thermal receiver which consumes at least one portion of the heat generated by the catalytic burner. The catalytic burner has a member for ejecting a flow of combustible gas, a member for admixing primary air with the flow of combustible gas to obtain a mixture to be burnt, a chamber for distributing the mixture, and a catalytic combustion structure in communication with the distribution chamber. The combustible gas travels into an upstream face of the catalytic combustion structure, and combustion exhaust gases are removed through a downstream face of the catalytic combustion structure. A radiating flameless combustion front is located in the vicinity of the upstream face of the catalytic combustion structure during operation. A thermal receiver extends along virtually the entire surface of the upstream face of the catalytic structure and receives thermal energy.

Abstract: A detector of pulses of electromagnetic radiation, especially of laser pulses, comprising as sensor at least one cylindrical body of material translucent to the electromagnetic radiation having a capture window on its surface of revolution. The cylindrical body is provided with an internal metallization delimiting the cylindrical body in two parts subject to selective photodetection, to obtain a sensitivity in bearing and/or in elevation. The body is extended at one end by a non-diffusing transparent part, likewise traversed by the internal metallization. The extension is externally metallized and serves for the link with photodetectors.

Abstract: The invention relates to a regeneration-type cryopump which has an annular reservoir for liquid nitrogen situated above an annular reservoir for liquid helium and incorporates, sliding in the central opening in the said reservoir, a valve member which is mounted on a rod. When the valve member is in one position, the cryopump is in normal operation, whereas when the valve member is in another position and rests against a seating, regeneration may take place.Such a pump may be used for generating very high vacua.
