Hydrocyclone device including at least one hydrocyclone having at least one feeding connector, at least one accepted stock connector, and at least one rejected stock connector. The method also includes receiving a second unidirectional connection request from a remote device coupled to an untrusted network, such as through a second firewall. The resonator may be placed against edges of the structures, to hold a different portion of the resonator spaced from an area where the waveguide modes will emanate. As a result, the amount of equipment required is relatively low. In one embodiment, an ordering temperature reducing layer of carbon is employed to lower the L10 ordering temperature of a FePtC recording layer.
