When communication is initiated, the portable transmitter and receiver are automatically retuned to one of the communications channels as determined by the strongest signalling frequency received by the portable receiver and by channel availability. Means are also provided in the system to continuously locate a portable unit and switch the operating frequency thereof as the portable unit moves between base station transmitter coverage areas. Further means are provided to automatically reduce the output power of each portable transmitter to the minimum level required for satisfactory communications in order to reduce battery drain and the interference caused by the portable transmitters.

Title: Metal extraction
IPC: C22B60/02
Filed: 1978-05-03
Abstract: In a process according to the present invention uranium is extracted into solution from its ore by leaching with an aqueous solution containing peroxomonosulphuric acid, the peroxoacid oxidizing the uranium through to its hexavalent state. Preferably the leaching is carried out at a temperature in the range of 50 DEG to 100 DEG C. The leach liquor can initially contain additional amounts of sulphuric acid or merely that present by virtue of the method of making the peroxomonosulphuric acid. In a preferred method of operation, the peroxoacid is introduced progressively into the leach liquor during the course of the leaching so as to maintain an electrochemical potential in the range of 450 to 650 mV. By use of the process, uranium is cleanly extracted into solution.

Title: Columnar structure
IPC: B63B15/02
Filed: 1978-06-14
Abstract: A hollow columnar structure fabricated from at least two, part-oval, extruded aluminium sections and intended for use as a sailing vessel mast or boom, a lamp standard or as piping. The sections each have a longitudinally extending groove along each of the longitudinal edges thereof, the grooves of one section being contiguous with the grooves of another when the sections are placed in position to form the columnar structure. Each groove is T-shaped in section whereby, when two such grooves come into co-operating relationship, the resultant cavity is of H-section. An H-shaped extrusion of synthetic plastics material is then inserted in each of the cavities to join the sections. The extrusions can be drawn through the cavities or can be extruded directly into the cavities. In an alternative form the structure is solid. In yet another form each aluminium section has an external formation which, in conjunction with a corresponding formation of another section, receives and retains a plastics material extrusion which in turn prevents separation of the sections.

Title: Tube expanding.
IPC: B23P11/02
Filed: 1981-06-04
Abstract: In a tube expanding technique for securing a sleeve (22) within a tube (24), fluid pressure is applied via a tube expander by incrementally decreasing the volume of the fluid system exclusive of the expander, or by incrementally increasing the mass of the fluid within the system. The system pressure and the rate of pressure increase are monitored as a function of incremental change in volume or mass. A decrease in the rate is indicative of the onset of plastic expansion of the sleeve (22) or tube (24), as the case may be. By determining this point, outer diameter of the tube may be accurately controlled to within 0.15 mm The tube expander includes a distensible sealed bladder (10) for applying the expanding pressure, the bladder (10) containing the system fluid.
