1.WO/1998/051387ULTRASONIC METHODS AND APPARATUS FOR SEPARATING MATERIALS IN A FLUID MIXTURE

WO - 19.11.1998

Clasificación Internacional B01D 17/04 Nº de solicitud PCT/US1998/009970 Solicitante SCOTT, Harold, W. Inventor/a SCOTT, Harold, W.

An efficient method of separating a first material from a second material in a fluid mixture is provided. The fluid mixture of interest is caused to flow through two different sonic wave fields. In one field, the sonic waves travel in a direction perpendicular to the direction of flow of the fluid mixture. In the other field, the sonic waves travel in a direction parallel to the direction of flow of the fluid mixture. The overall effect of the sonic waves in these two fields is to irreversibly break any molecular bonding between a substantial portion of a first material and a second material in the fluid mixture. In one embodiment, the perpendicular-directed sonic waves are cavitation waves and the parallel-directed sonic waves are standing waves.

A vehicle-mounted information terminal device (10) mounted on a vehicle transmits vehicle position information detected by a navigation device to a fixed station (20). The fixed station (20) stores the received position information and provides the position information on each vehicle in response to a read request from a communication terminal device such as another vehicle-mounted information terminal device (10), a personal computer (30), a mobile personal information terminal device (40), and a mobile telephone (50). In this position information provision, a user can select to reject information provision. Moreover, it is possible to provide information to a particular group of members. Accordingly, it is possible to widely notify the current position of a mobile body such as a vehicle.
