Abstract: A tank contains a liquid while being transported by a moving vehicle. The tank includes a shell having an annular wall interconnecting opposite longitudinal end walls. The annular wall and the end walls define an interior compartment. The shell also has a substantially horizontal length direction and a substantially horizontal width direction perpendicular to the length direction. Two substantially planar longitudinal baffles are disposed within the interior compartment of the shell. Each longitudinal baffle is oriented substantially vertically and substantially parallel to the length direction of the shell. Each longitudinal baffle has a first side facing the annular wall. Each longitudinal baffle also has a second side. The second sides face each other. A plurality of substantially planar latitudinal baffles are disposed within the interior compartment of the shell. Each latitudinal baffle is oriented substantially vertically and substantially parallel to the width direction of the shell.

Abstract: Self-programming scanning receiver having superheterodyne circuitry, microprocessor controlled synthesized frequency tuning circuitry, frequency validation means, a learn mode to invoke the frequency validation means for all frequencies tunable by the tuning circuitry, listen mode for scanning of frequencies learned in the learn mode, and an ignore mode for erasing frequencies from permanent memory.

Abstract: A transportation vehicle alert monitor incorporating a speech synthesizer for voice announcement of vehicle location by stop number. The monitor includes a radio receiver responsive to coded RF signals containing either current vehicle location data or data for programming the monitor. Current location data includes school system number, bus number, route number, and stop number. Programming data includes school system number, monitor serial number, student number, two route numbers for one bus number, and initial and final alert stops for each route. Programability of initial alert stops allows each alert monitor to be remotely adjusted to allow varying conditions including the discharge between adjacent stops, traffic conditions, and distance from a passenger's house to the stop.
