Abstract: A method and apparatus for automatically associating physical network addresses with logical identifiers in local area networks. The physical network address is transmitted to a central administrator of the local area network, where the association between such address and a logical identifier is made. In the case where a new device is being installed on the network, the logical identifier may be an arbitrary word, number, or combination thereof which is supplied by the operator at the central administrator. In the situation where a device is being replaced, the logical identifier is the same as the identifier of the replaced device, while the physical network address of the replacement device is substituted in the association for the address of the replaced device. A compilation of the associations is maintained at the central administrator, and the associations are transmitted back to the devices being installed or replaced, as well as other devices on the network. A removal procedure is also utilized, whereby a selected association(s) may be removed from the system.

An outer portion of the plastics material is then allowed to set at least partially within the mould cavity whereupon the shutter means is removed and a quantity of the plastics material is displaced from inside the mould cavity through the outlet so as to form a hollow object in the mould cavity which is then allowed to set completely within the mould cavity. The method is particularly adapted for use with a gas injection moulding technique and also allows for the displaced plastics material to be consolidated to an outer wall of the moulded object.

Abstract: The axial flow turbine has an asymmetrical flow input, for example, at the first nozzle plate (12/S1), which flow is attenuated towards an axi-symmetric flow by a baffle plate (40) located between the first nozzle plate and the second stage (S2). The baffle plate directs the flow towards a more symmetrical flow pattern before permitting the flow to pass through the second stage. Consequently, the long turbine blades in the later stages of the turbine respond to an attenuated asymmetrical flow rather than a larger asymmetrical flow which might induce vibrations or vibrations at the natural resonant frequency of the turbine blading which could break the turbine blades.
