Patent DE-19527446-A1 (DE)
Title: Method for optical surface inspection of workpieces
Inventor: WAHL GERD DIPL ING
IPC: G01N21/89
Filed: 1995-07-27
Abstract: Based on the light intensity function (G<x>) of the half tone lines of the reference surface (G) and its inverse function (H<x>), from these functions half tone matrixes are generated, expressed in pixels, which are combined according to the expression Gm,n.Hm,n = K, with m, n the indices of the matrix elements and K a freely selectable constant. For the workpiece a matrix Sm,n is generated (Sm,n = Im,nHm,n and I and H referring to the workpiece) cleansed of the original local differences in light intensity from which is deducted the constant K to derive a function (B<x>). The surface structure half-tone matrix (Bm,n = (Im,n-Gm,n).Hm,n) is then generated with improved contrast and regardless of the original local background light intensity. This matrix is then evaluated according to the sample recognition algorithm appropriate to the test function.

Patent DE-19541058-A1 (DE)
Title: Tunnel spectroscopy method for electronic condition and density of material
Inventor: SCHWABE NIKOLAI F
IPC: G01N27/60
Filed: 1995-11-03
Abstract: The method uses a mesoscopic tunnel point (4) suspended above the sample (1) from the bridging beam (3) between two piezoelectric tripods (2L, 2R). A vacuum space (5) of 1nm forms the tunnel barrier between point and sample. The exchange effect of a tunnelled electron over the vacuum barrier changes with the oscillating quantum of the suspended tunnel point. An acute resonance in the differential conductivity and in the derivative spectrum of the tunnel barrier will result from a direct change of resonance frequency at the tunnel point or through a change of absolute potential.

Patent DE-19609204-A1 (DE)
IPC: A61L2/20
Filed: 1996-03-09
Abstract: The invention concerns a process and device for scrubbing waste gases from a desorption device of a steriliser in which articles requiring sterilisation are exposed to ethylene oxide gas to kill microbes. In the desorption device (1) the sterilised articles are exposed for at least forty eight hours to an air stream in a closed air circulation (1-44-5-6-8-7-9-60-1) which takes up the desorbent ethylene oxide and draws the air/ethylene oxide gas mixture into a scrubber (8) containing a scrubbing liquid consisting of 1-6 % sulphuric acid, thereby creating a large phase boundary surface. The ethylene oxide passes into solution in the scrubbing liquid as ethylene glycol and the air stream is then fed back via a filter (7) into the desorption device (1). The mean ethylene oxide gas concentration is constantly lowered by scrubbing inside the desorption device (1) sufficiently to ensure that the ethylene oxide concentration in the supply air stream is less than the ethylene oxide concentration at a given instant inside the desorption device. The air circulation is then interrupted and the air stream with very low ethylene oxide residues is discharged from the desorption device (1) to the outside. The scrubber is either a tower packing- or scrubbing column (8) through which a circulation (8-10-11-12-13-16-19) of the scrubbing fluid is maintained.

IPC: G01F1/708
Filed: 1996-10-19
Abstract: According to a method of measuring the speed or throughflow of flowing or moving media, the medium movement is determined according to statistical chronological variations in the medium properties, and a corresponding sensor signal is differentiated. This method is to be improved such that throughflows or speeds can be measured economically. To that end, the statistically distributed individual signals (d) obtained after differentiation and corresponding to the edge steepness in the sensor signal (s) are determined according to their amount and subjected to a mean-value generation process which is independent of their sign.
Patent DE-19645577-A1 (DE)
Title: Exhaust quality monitor for IC engine
Inventor: MATUOKA HIROKI
IPC: F02P5/15
Filed: 1996-11-05
Abstract: The catalytic converter is fitted with an electric heater to ensure that the operating temperature is rapidly reached, especially during cold start. The control system monitors the voltage drop across the heating element and the heater current to compute the expected temperature. This is compared with an optimum reference temperature to calculate the changes required to the fuel/air mixture in order to generate additional heating in the catalytic converter to raise the temperature to the optimum operating level. The engine management system controls the input airflow into the inlet manifold and the ignition timing to vary the heating effect in the catalytic converter. These parameters are controlled with respect to the engine speed. In the event of abnormal conditions which prevent correction to the heating effect a fall-back setting is used in which a heating effect corresponding to normal operation is used.
