Abstract: A fixed portion (102) of a radio messaging system schedules (602) an inbound message to be transmitted at a first scheduled time on a channel from a portable subscriber unit (122). The channel is monitored (604) at the first scheduled time to receive the inbound message, utilizing a beamforming technique. In response to failing to achieve adequate reception of the inbound message at the first scheduled time, the fixed portion reschedules (608) the inbound message to be transmitted at a second scheduled time, and remonitors (610) the channel at the second scheduled time to receive the inbound message, utilizing an omnidirectional technique.

Abstract: The present invention relates to a process for the production of intermediates useful in the processing of mineral sands and related materials characterized in that the process comprises:(a) dissolving a metal fluoride or metal chloride compound in an organic solvent; and either(b)(i) adding an ammonium fluoride to the metal fluoride or metal chloride compound dissolved in the organic solvent in step (a) to precipitate an ammonium fluorometallate from the organic solvent; and(ii) dissolving the ammonium fluorometallate from step (b)(i) in water and adding an alkali fluoride or an alkali chloride or an alkali nitrate to produce an alkali fluorometallate and an ammonium fluoride or an ammonium chloride or an ammonium nitrate; or(c) optionally adding the metal fluoride compound dissolved in the organic solvent in step (a) to an alkali fluoride dissolved in water or in aqueous hydrogen fluoride to produce an alkali fluorometallate directly.

Abstract: A mounting system, for supporting semiconductor process gas delivery and control components for assembly and use as a gas stick, aligns the connection union seals between fittings on adjacent components to absorb accumulated stresses resulting from manufacturing tolerances and reduce the likelihood of seal leakage. Components are mounted on individual upper clamp members which are secured to lower clamp members to form a slidable but non-rotatable radially aligned yoke around a rigid elongate support member for subsequent longitudinal positioning and joining of adjacent fittings.
