Title: Fuel control system
Inventor: STUCKAS KENNETH J
IPC: F02D41/26
Filed: 1982-10-14
Abstract: A fuel control system for a spark ignition internal combustion engine of the type having a source of fuel and a pump for supplying the fuel from the fuel source and to the engine at variable flow rates. The fuel control system of the present invention is particularly suited for a reciprocating piston aircraft engine and is designed to minimize brake specific fuel consumption of the engine during steady state engine operation. The fuel control system utilizes a microprocessor to determine the peak value of the exhaust gas temperature and, once the peak has been found, repeatedly decreases the fuel flow rate to the engine in predetermined increments until the exhaust gas temperature is less than its peak value by a predetermined amount. At this time, the fuel control system maintains a constant fuel flow rate to the engine.

Abstract: A mobile crane runs on rubber wheels in lanes in a container yard. Passive ground devices (5) are installed in the path of the crane, each ground device comprising a different linear array of metal plates (51-5g) present or absent in each of a number of regular positions along the array. Each ground device thereby provides specific positional information. A beam (10) is mounted beneath the crane and carries a row of proximity switches (121-12g) registrable in one-to-one relationship with the metal plate positions to detect the specific positional information. The beam has further wheels (11a, 11b) at opposite ends to maintain the detecting means clear of the ground, and the beam is mounted by expandable means (17) to absorb vertical movement of the crane due to compression of the rubber wheels under load. <IMAGE>

Filed: 1982-12-02
Abstract: A recorder, e.g. a multi-channel instrumentation tape recorder with tape mechanism 5, has control and display section 12 including CRT 14 for selectively displaying signal parameters relating to the channels of the recorder. The CRT can display information in a variety of different formats or "pages", selectable by push buttons 20. One page may e.g. display simultaneously the input or output levels of all channels each as a respective bar graph. In another page, the CRT provides alphanumeric identification of a variety of different signal parameters such as "bias", "input level", "output level", and others. By rotary control 26, an operator can move a cursor to any one of these parameters, and a further rotary control 28 is then used to select a particular channel. By rotary control 24, the operator can then adjust the selected parameter in the selected channel, and a bar graph on the screen displays the value of the parameter. <IMAGE>
