Abstract: A jointing strip for jointing by welding at least two portions of a plastics material or of two different plastics materials includes a substantially H-shaped plastic member with apertures defined by opposing jaw portions. Electrically conductive elements, for example foil portions, are located at or near to a surface in the apertures of the respective jaw portions. The edge portions of the plastics materials to be welded are inserted in the apertures.

Abstract: A technique for integrating a pre-existing business system with a fleet management system. The pre-existing business system includes, for example, an accounting system, a warehousing system, a dock management system, a yard management system. These fleet management system uses, for example, a combination of a raster map and vector data to provide an easy-to-read display for managing objects or articles, e.g., vehicle, container. The method uses a host gateway to provide a TCP/IP or like interface between the various systems.

Abstract: Apparatus for production of liquid from wells such as petroleum wells includes well pipe that extends from the surface downwardly to the level of liquid standing within the well. A string of production tubing is positioned within the well pipe with the annulus between the production tubing and well pipe defining gas supply means that is interconnected with a source of compressed gas. At the lower portion of the production tubing is located aspirator means having a gas injection element defining a gas jet passage which is in communication with the gas supply annulus. The gas injection element is oriented to direct an upwardly flowing jet of pressurized gas which is directed into the lower restricted portion of a venturi that extends upwardly from the aspirator means into the production tubing. The aspirator means also defines a liquid flow passage that is in communication with liquid standing within the well.
