Abstract: A method and apparatus for measuring at least one moment acting about a predetermined axis on an object under investigation. A force component acting at a first force introduction point onto said object under investigation perpendicular to a normal from said first introduction point to said axis is measured. Then a differential moment caused by displacement of said object between said first force introduction point to a present second force introduction point is determined and said displacement is calculated by dividing said differential moment by said measured force component. A predetermined distance between said first force introduction point is corrected by said displacement and finally said measured force component is multiplied by said corrected distance in order to gain an accurate value for the moment to be measured.

Abstract: In a method and apparatus for measuring the pressure of a liquid in a closed storage tank, a measuring piston is guided in a cylinder and is acted upon on one side by a pressure dependent on the pressure to be measured, the piston being in communication with a load measuring device. In order to compensate for the pressure exerted by gas and/or vapor in the interior space of the tank, that side of the piston opposite to said one side is acted upon by this pressure. This is achieved by enclosing the cylinder and the piston in a container filled with a blocking gas, such as nitrogen. The pressure of the blocking gas in the container is controlled by a regulator operation of which is controlled by sensing means for sensing the gas and/or vapor pressure in the interior of the tank.

Abstract: A method and apparatus for checking the functions of a display system display data which is received from a processing unit, store the displayed data, and check the stored data for identity with the data which is to be received and displayed. The check determines not only whether the display system has properly received the data, but also checks for malfunctions in the display system itself, such as a short circuit or an open circuit within the display unit, because the stored data can only correspond to the data intended for display when no malfunctions have occurred in either the display system or in the circuit for receiving the data.
