Abstract: A machine for assembling rebar cages includes a support frame, axial rollers mounted to the support frame for rotatably supporting a cylindrical wire cage for axial rotation about an axis of elongation, a carriage movably mounted to the support frame for translation, with the carriage adapted for driving an elongate rebar rod in a first axial direction. A drive mechanism is mounted to the support frame for driving the carriage in translation back and forth between a retracted position and an extended position for driving rebar rods into the rebar cages for assembly.

Abstract: A method of applying a policy to a text comprises searching the text for data having a predefined form; and searching a dataset for additional data associated with any data having the predefined form found in the text. A supplementary search query is generated using said additional data; and the text is searched using the supplementary search query. The policy is then applied based on a result of the search using the supplementary search query.

Abstract: A safety system for alerting occupants of a fire or smoke occurring within a building in which the safety system includes a smoke detector associated with an electric door release mechanism of a locked door that is energised to unlock the door automatically in response to receiving a signal from a control unit which in turn receives a signal from a smoke detector when fire or smoke is detected so that the door is automatically opened by the electric door release mechanism being released by movement of an electrically operated striker plate to allow occupants trapped within the building to escape from the burning building, whilst allowing access to the building for emergency rescue personnel.

Abstract: A module for controlling the temperature within an enclosed structure is provided. The module comprises a thermoelectric assembly, a platform, and a panel. The thermoelectric assembly comprises a thermoelectric device with a first heat sink disposed on one side of the device and a second heat sink disposed on the other side of the device. The thermoelectric assembly further comprises an electric motor attached to one of the heat sinks with a rotating shaft extending longitudinally through the electrical motor and both heat sinks. A propeller may be attached to each end of the rotating shaft adjacent to the first heat sink and the second heat sink respectively. The platform may be removably engaged with the enclosed structure. A first fastener may be used to attach the thermoelectric assembly to the platform. A first opening may be provided in the platform adjacent to one of the propellers.

Abstract: A transport apparatus, for hauling data storage media requiring environmental protection to and from a permanent storage site, includes a portable transport module and a transport cart. The transport module includes an insulated housing having guides for receiving shelves adapted to hold motion picture films, audio and video tapes, and photography film and provide ready access to and protection against movement during transit. A thermoelectric heat pump assembly heats or cools the interior of the insulated housing. A temperature sensor and a humidity sensor in the housing produce temperature and humidity measurement signals. Connectors are provided to connect power to the thermoelectric heat pump assembly and to output the temperature and humidity measuring signals. An ancillary power supply and control system are included to operate the transport module when separated from the transport cart.

Abstract: Disclosed is a removable, replaceable assembly for supporting a file system of the type which has a plurality of separator cards each of which is centrally apertured near its bottom to receive a locking rod. The cards are assembled behind the other. The assembly includes a pair of spaced parallel pivot rails (2, 4). Each rail has an upper pivot surface (6) lying in a common plane on which the bottom portions of the cards are supported for pivotal motion. Means (10, 36) join the pivot rails together and are located below the pivot surfaces of the rails. A locking rod (20) is located midway between the pivot rails of extends parallel to the rods and passes through the apertures in the separator card. Rod retaining means (24) extend upwardly from the joining means and are releasably engagable with the locking rod. The retaining means are apertured to position the rod between the rails at or below the plane of the pivot surfaces of the rails.
