  • Publication number: 20200147883
    Abstract: Tins invention relates to apparatus for producing a three-dimensional object by spray deposition. The apparatus has a powder conveyance line A line arranged to channel 5 a flow of spray material entrained in a carrier gas to a nozzle (a first flow). The apparatus also has a process line B arranged to channel a flow of gas to the nozzle (a second flow). The apparatus also has a spray nozzle 8. The apparatus is such that pressure and temperature parameters of the first flow are controlled in real time, but for the second flow these parameters are not controlled in real time. The two flows 10 merge to cause spray material to be propelled from the nozzle 8 to a substrate to create a three-dimensional object.

  • Patent number: 9041264
    Abstract: An axial flux electrical machine including a housing, a stator located within the housing, a rotatable shaft carried by the housing by means of at least a main bearing, and a rotor fixed to the shaft within the housing. Magnetic attractive forces between the rotor and the stator produce an axial thrust on the main bearing and a biasing means (preferably in the form of a spring) is arranged to urge the shaft in a direction opposite to the axial thrust so as to reduce the net load on the main bearing. This reduction in net load on the main bearing increases bearing life and improves motor efficiency.

  • Patent number: 8061171
    Abstract: The present invention provides a method and machine for producing a slotted wound core (50). The machine includes a punch arrangement (16) arranged to punch apertures in a length of material (12a), a mandrel (22) for receiving the punched material, a control means and a mandrel indexing means. The positioning of the punch arrangement (16) and the mandrel (22) is fixed and the mandrel (22) is arranged to be rotated by the mandrel indexing means after each operation of the punch arrangement so that a roll of punched material is formed on the mandrel (22). The mandrel (22) is rotated by an amount (&ggr;) determined by the control means. The control means determines the indexed amount so that selected apertures punched in the length of material align with one another when the material (12a) is rolled onto the mandrel (22) so that the aligned apertures form respective slots (52) of a desired configuration in the core (50).
