Title: IC engine correction system - uses switch to pass correction signal to control unit when measured parameters remain constant
Inventor: GEIGER ISTVAN DIPL ING
IPC: F02D41/14
Filed: 1978-10-27
Abstract: The correction system measures the fuel flow rate and flow quantity. A correction (a difference signal) is only passed to the engine's control unit if one of a given set of engine operating parameters has remained practically constant for a given min. period of time. The correction is obtained by averaging a given number of measurements and can be made to apply to any mode of engine operation (no load, partial load, full load). The wanted values of the measured variables are stored for comparison with the actual measurement in order to produce the correction signal. The correction signal is switched through to the control unit by a switch that only closes when the parameters have stayed constant.

Patent DE-3009476-A1 (DE)
Inventor: KADLEZ KARL DIPL ING DR TECHN
IPC: B23K9/23
Filed: 1980-03-12
Abstract: In order to obtain as far as possible a finely graduated transition from the low concentration of the alloying element in workpiece (A) to the higher concentration of this alloying element in workpiece (B), a transition zone (C) is created between the two workpieces (A, B) when the welded joint is being made. The transition zone (C) is created by overlapping welding beads (1, 2, 3) with in each case an increasing concentration of alloy metal. Each of the three overlapping welding beads (1, 2, 3) has a higher concentration of alloying element than the workpiece (A) or the respectively preceding welding bead, the concentration of this element in the last welding bead being lower than that of the workpiece (B). This results in a finely graduated, virtually continuous increase in the concentration of the alloying element. <IMAGE>
