Patent DE-2342330-A1 (DE)
Title: Flue gas fan motor controller - alters r.p.m. dependent on reduced press. at boiler connection, sensed by vacuum sensor
Inventor: SCHWANK GERHARD
IPC: F23N3/08
Filed: 1973-08-22
Abstract: Control to switch on and off, and alter the r.p.m. of, the fan motor of a flue gas fan for boiler plant fuelled with light oil, and with a filter in the flue gas takeoff and a vacuum sensor to measure the reduced press. at the boiler connection, has the fan r.p.m. automatically regulated in dependence on the vacuum sensor, which is set to a given reference value. At excessively reduced press., the r.p.m. is immediately reduced, but with too small a press. reduction the r.p.m. correction is effected after a min. time delay. The fan, at the beginning of each combustion phase, starts simultaneously with the burner motor, with the same r.p.m as at the end of the preceding phase, and maintains this initial r.p.m. for a given time. With too low a press. reduction maintained for too long, after a given period the burner and flue gas fan can be switched off, with simultaneous display of a fault signal. Optimum regulated and uniform operation is obtd.

Title: Surface irregularity determination - by scanning radiation density distribution image and averaging power of converted signals
Inventor: EHRLER PETER DR ING
IPC: G01B11/30
Filed: 1973-11-13
Abstract: The rays reflected by an irregular textile of paper surface are portrayed on an optoelectronic transducer layer as a radiation density distribution image. This is scanned line-by-line and converted to electrical signals. The power of the signal which fluctuates around an average level is measured by a broadband power meter, it is found to be proportional to the variance s2. This creates an objective means instead of the present subjective assessment of the irregularity of textile or paper surfaces which depends on the human element. This system is simpler than radioactive methods.
