Patent EP-0280288-A2 (EP)
Inventor: PARKER DAVID HIRAM
IPC: G01M17/02
Filed: 1988-02-25
Abstract: A method is disclosed for evaluating the level of objectionable noise associated with the operation of a tire by virtue of its tread contacting a road surface, which comprises digitizing the tread design on a coordinate system so as to define load-supporting portions of the tread in contact with the pavement, and distinguish them in binary form from those portions of the tread which are not in contact, as multiple matrix elements; defining a generally arcuate profile of a leading or trailing edge of a footprint of the tread by fitting an equation to the edge; sequentially performing the time ensemble summation, of the noise produced by each matrix element, over every matrix element on the entire circumferential surface; converting the sequence of summations to a periodic analog signal; converting the analog signal to a sound; and, aurally evaluating the sound. In a simplified case 0's and 1's along at leas, one footprint edge are sequentially summed around the circumference of the tire. The system requires only a means for digitizing the tread pattern, a computer to perform the necessary manipulations of data, and a means to convert a digital signal to an analog signal.

Abstract: The chimney cowl is provided with a pipe connection piece (1), a truncated pyramid-shaped inner jacket (2) which projects upwards above the pipe connection piece (1), and a truncated pyramid-shaped outer jacket (4) which projects upwards above the inner jacket (2). The upper outlet opening (5) of the outer jacket is covered by a cover part (14) arranged above it. In order, even in the most extreme wind strengths and wind incidence directions, to prevent rain entering the chimney with pressure fluctuations in the outlet opening region of the chimney which are as small as possible and to improve the separation of the waste gas plume from the chimney cowl, there is arranged inside the upper part of the outer jacket (4) a cylindrical flow guide part (15) which projects upwards above the latter and is widened at the bottom. The lower inlet opening (16) of this part, which is widened downwards and outwards, projects beyond, seen in the axial direction of the cowl, the upper outlet opening (6) of the inner jacket (2) so that liquid condensing on this flow guide part (15) does not drip down into the chimney but onto the outside of the inner jacket (2) and evaporates there or on the cover and support plate (11) which is likewise heated. <IMAGE>

Abstract: In a method for cleaning earth soils or similar soil materials polluted with organic harmful substances, the latter are extracted by means of a suitable solvent from an aqueous suspension of the soil materials. After the solvent which has taken up the extractable organic harmful substances, the solvent is distilled and recycled into the process. The distillation bottom product, which contains the extractable organic harmful substances, is disposed of, for example, by incineration or in a landfill. The remaining suspension is separated into water and soil, and the aqueous phase is recycled into the process. If the water is polluted with free cyanides, it must be passed over a purifier earth for removing the cyanides, before it is used again.

Abstract: The invention relates to an airflow mill arrangement having a roller mill which has fixedly mounted mill rollers. The mill rollers can be pressed resiliently against a driven mill bowl. An integrated sifter is arranged over the roller mill. In this embodiment of the mill arrangement the mixture of material for milling and air is fed essentially from the roller mill centre to the mill bowl and the millrollers. Since, hitherto, the rotation of the mill rollers was brought about by means of a frictional connection to the material for milling or the milling bowl extreme loads and slip-stick effects could not be ruled out. In order to overcome these disadvantages, the invention employs the method of also separately driving the mill rollers in a combination, in which case speed of revolution and torque are configured in such a way that even in the case of a high degree of fineness of the material for milling a uniform mode of operation of the mill arrangement is ensured. <IMAGE>

Abstract: A radio telecommunication apparatus is used in a radio tele­communication system wherein one or more base stations broadcast radio signals over a plurality of radio channels. The apparatus selects at least a radio channel out of the plurality of radio channels and detects the availability of the selected radio channel. In response to the unavailability of the selected radio channel, the apparatus is intermittently powered so as to detect the availability of the selected radio channel while conserving battery power consumption. Even if the availability of the selected radio channel is detected, only recep­tion and transmission sections are intermittently powered so that the presence of information signals to be transmitted is detected.
