Title: Low oil pressure warning for automobile - has circuit energising audible warning instead of visual indication
IPC: B60R16/023
Filed: 1977-03-11
Abstract: An electric circuit receives a supply from the vehicle bettery (5). The circuit runs through a switch (4) connected to the armature (2) of a microphone (1). The switch makes and breaks the current through the coil (3) of the microphone. The circuit is completed by a manually operated switch (7) and a pressure switch (6) in the vehicle oil sump. The manual switch enables the circuit to be put in or out of use as required and the pressure switch makes on fall of pressure. The circuit provides audible warning of low oil pressure which is more convenient than the conventional visible warning systems.

Patent FR-2373298-A1 (FR)
IPC: B64D1/16
Filed: 1977-12-09
Abstract: An open water container (1) is rotatably mounted on a bow (2) which is attached to an aircraft. The horizontal axis of rotation (3) extends below the centre of gravity (12) of the filled container (1). In the unstable position, in which the container opening (10) is at the top, a locking device (13, 16, 19) secures the container (1) against rotation. Over the fire, the locking device (13, 16, 19) is released while the aircraft is stationary or flies slowly. The container (1) then automatically rotates from its unstable position through approximately 180 DEG , which causes it to empty its contents completely in an instant, making all the water drop onto the fire in a single mass. In this process, evaporation from the water surface, which is small in relation to the volume, is negligible and virtually the entire quantity of water has an extinguishing effect, even above the ground surface, so that even burning treetops are extinguished. Furthermore, the pressure of liquid on the ground is insufficient to spray out and carry along any burning pieces, and so spreading of the fire is avoided in a reliable fashion.
