A method for lining a pipe conduit with a coated textile tubing that adheres to the inner walls of the pipe conduit by means of an adhesive. The coated textile tubing can be filled with a long pot life adhesive and the textile tubing turned inside out (inverted) while being introduced into the pipe conduit. A fast curing adhesive is substantially simultaneously applied to the inner wall of the pipe conduit in as short a distance as possible to the moving tubing inversion point. The introduced tubing is then subjected to an inner pressure to force the tubing into contact with the pipe inner wall until the fast curing adhesive has cured. Alternatively, an impregnated textile tubing can be substituted for the tubing filled with the long pot life adhesive. As a further alternative, conditions are controlled to cause curing of the adhesive only in the inverted portion of the tubing.

A multiple layer label and a method of making the same are provided. Specifically, a label having a base layer for adhering to a container is provided wherein the label has an overcoat layer having an end that is removably adhered to the container. Moreover, the end that is removably adhered to the container is grasped by a user of the label and pulled, thereby removing the end of the overcoat layer from the container and swinging the layer away from the remainder of the label and exposing sublayers beneath the overcoat layer. The overcoat layer is adhered directly to the base layer, and at least portions of the sublayers. Each of the overcoat layer, sublayers, and the base layer may have indicia printed thereon for communicating information.

A method for regulating a generator in a motor vehicle, in which the generator feeds a vehicle power supply system having loads and having at least one battery, with a regulator regulating the generator output voltage at the value of a nominal value voltage. In a recuperation readiness mode, the nominal value voltage is preset as a function of the driving state variables such that, during braking or when the vehicle is overrunning, electrical power is fed into the vehicle power supply system. Switching takes place between the recuperation readiness mode and a recovery mode as a function of predetermined switching conditions, with the nominal value voltage in the recovery mode being preset such that the battery is regenerated.

In a method of determining air humidity, a capacitive moisture measuring element (2) used in a moisture sensor for calculation operations is modelled by a parallel circuit of an ideal capacitor (C) and an ohmic resistance (Rp). Charging and/or discharging of the capacitive moisture measuring element (2) by way of a first measuring resistor (R1; RA) provides for ascertaining a first time constant or a first period duration of the charging and/or discharging operation, and charging and/or discharging of the moisture measuring element (2) by way of a second measuring resistor (R2; RA//R) provides for ascertaining a second one. The capacitance (C) of the moisture measuring element (2) is then calculated from the two time constants or the two period durations, a value for the moisture level finally being ascertained from the capacitance. This method achieves a higher level of measuring accuracy on the part of the moisture sensor.

A method for preserving color information in a black and white version of a color image includes the analysis of the color image. The analysis comprises a search for conflicting colors. Conflicting colors are colors that are normally transformed to the same gray level in a black and white version of the image. One embodiment, working in a CIELAB color space includes the use of a three dimensional histogram for detecting predominant colors having the same luminance. Such colors are classified as conflicting colors. Modulations are added to the gray scale versions of conflicting colors in order to make them distinguishable. Modulation is only applied to conflicting colors thereby minimizing any deleterious effect and allowing the method to be applied in a “walk up mode” of an image processor. An image processor operative to perform the method includes an image analyzer operative to find and classify conflicting colors in the color image, and a gray scale modulator operative to add modulations to gray scale versions of only the conflicting colors within a gray scale version of the color image.

A screw-type solid-bowl centrifuge including a rotatable drum having a tapering portion and a cylindrical portion. The rotatable screw includes a screw body, at least one main screw blade surrounding the screw body and forming a plurality of screw flights. The plurality of screw flights forms a conveying path configured to transport a material to be processed in the centrifuge. Two blade segments are arranged in the conveying path in portions of the plurality of screw flights. The at least one main screw blade is provided in a region of the blade segments that includes clearances configured to allow a throughflow of the material to be processed to flow between adjacent screw flights.

In a method of determining air humidity, a corrected moisture signal is calculated for a moisture signal (Hi) ascertained from electrical properties of a capacitive moisture measuring element. In a measuring phase (30) with rising relative air humidity (RH), the corrected moisture signal is the current moisture signal (Hi) increased by a correction value, whereas in a measuring phase (31) with falling relative air humidity (RH) the corrected moisture signal is the current moisture signal (Hi) reduced by a correction value. Depending on the respective properties of the moisture measuring element and the required degree of measuring accuracy, the correction value is constant or is taken into consideration in dependence on the relative air humidity RH. This method provides a higher level of measuring accuracy with a moisture sensor equipped with the moisture measuring element.
