Title: Washed fabric surface testing - uses digital image of illuminated surface for image data to be used with standard deviation as measure of surface character
Inventor: MUELLER-KIRSCHBAUM THOMAS DR
IPC: G01N33/36
Filed: 1991-10-04
Abstract: To evaluate the surface characteristics of textile fabrics, they are illuminated for an image to be digitised to give image data for one or more characteristics as a measure for the surface character. After the continuous or quasi-continuous grey value or colour intensity distribution for the image digitising, their standard deviation together with only two lightness values of the grey and intensity distribution and/or the number of surfaces with the same light value as registered. A measure for the surface character is calculated from their values, if necessary after calibration with a standard. Pref. to evaluate creases in wovens, the surface image is taken from an angled light, the image is digitised to give the standard deviation (sigma) for the ironing stage (GS) as CS = (const/sigma) - contg.. The image is taken by a monochrome video camera. The constants depend on the lighting ratios with a comparative standard. To evaluate the absorption of textile treatment media, esp. fabric softeners, adsorbed medium is caught on a colour image through even illumination, the image is digitised, the standard deviation of colour bleed is established and the consistency (GL) is calculated using sigma arithmetically as GL = const/sigma. Only the colour bleed of the complentary component of the marking dye is used to determine the mean standard deviation. The constants contain corrector terms, according to the fabric type of 1/1+delta). The results are calibrated by a visual standard. From the digital monochrome image for dye depression changes, the standard deviation (sigma), the mean value (m) and the density medium (d) are used to calculate the values FV = sigma(T) - sigma(A) + m(T) - m(A) + d(A) - d(T), (where T is the textile material under test and A the starting textile, using a camera at right angles to the fabric surface and a visual standard for calibration). USE/ADVANTAGE - The technique is used to determine the fabric character and colour after washing with various chemicals. It gives standard results, rapidly, to show the fabric surface quality, to quantify the results in a form which can be reproduceith
Patent DE-4136980-A1 (DE)
Inventor: KLOSE HANS-PETER DIPL ING
IPC: H03K7/08
Filed: 1991-11-11
Abstract: A device for modifying the pulse duty factor or the pulse number density of a signal sequence has a ramp generator (10) and a first storage (12) with a stored value that predetermines the pulse duty factor or the pulse number density. Output signals of the signal sequence can be triggered when the ramp values produced by the ramp generator (10) exceed or fall below the stored value. A second storage (15) that may receive different stored values for predetermining the pulse duty factor or the pulse number density of the signal sequence is linked to a comparison stage (14) that compares the stored values of the first storage (12) with those of the second storage (15). In addition, means are provided for gradually adapting the stored value of the first storage (12) to the stored value of the second storage (15) when the comparison stage (14) detects a difference. This device allows the pulse duty factor to be automatically and gradually adapted to new conditions, even when these occur abruptly.

Patent DE-4211157-A1 (DE)
Inventor: PFAFF DIETRICH
IPC: H02B13/075
Filed: 1992-03-31
Abstract: In the earthing switch described, the mobile earthing contact (3, 11) is located, for measurement purposes, in such a position that it is insulated with respect to the earthed cladding (1). The insulation of the earthing contact (3, 11) is by-passed, for the functioning of the earthing switch, by an electrical connection located preferably outside the cladding (1). This insulation is by-passed when the earthing contact (3, 11) is connected, in the closed position, to a measurement instrument. The invention calls for an additional contact assembly (7, 7a, 8, 8a) which positively by-passes the insulation and which connects the mobile earthing contact (3, 11) during the switching movement, at a position other than the on/off position, with the earthed cladding. The invention thus enables overload voltages caused by discharges in the insulation, and possible damage to measurement instruments connected to the earthing switch, to be reliably avoided.

Title: Geometrically accurate glass prodn. - uses external pressure on glass against master surface, for further glass to be bonded with putty
Inventor: DOCTER BERNHARD
IPC: B32B17/10
Filed: 1992-04-18
Abstract: To produce a glass surface of high accuracy and stability, a flat glass pane is pressed through external force against a glass or metal block shaped to give the complementary master surface. The rear surface of the pane is covered with a glass pane of the same thickness and the two are puttied together as a compound glass structure. A vacuum is pref. generated between the glass and master surface for the external pressure to be applied on the glass through atmospheric pressure. The glass and the block are preheated. For a cpd. glass structure with two glass materials, both glass panes are pressed externally against a master surface for each. The gap between the master surfaces, parallel to each other, is slightly larger than the thickness of the two glass panes. The panes are pref. bonded together by a putty with the same refraction index. One master block is static, and the other master block slides towards it so that, after the application of the putty, both glass panes are pressed against the static block. USE/ADVANTAGE - For prodn. of a glass surface with a high geometric accuracy, especially as a mirror surface, and lenses. The method gives an accurate glass material, without expensive grinding and polishing.
