Title: Large-calibre pipe of thermoplastic material
Inventor: ANASTASSAKIS COSTAS
IPC: F16L9/16
Filed: 1990-09-19
Abstract: ABSTRACT OF THE DISCLOSURE     A large-caliber pipe consisting of thermoplastic, constructed from an extruded hollow plastic profile having helical turns welded along a helical contact seam. The hollow plastic profile is a multi-cell profile having a rectangular overall cross section and a rectangular cross section of the cells.  The plastic has an integrated reinforcement consisting of embedded fibers in a quantity of 5 to 30% by weight, preferably about 10% by weight, based on the total weight.  At least a proportion of the fibers is oriented in the direction of the turns.  The orientation of the fibers results in an anisotropic modulus of elasticity and hence an increased annular rigidity and stability.

Abstract: Anchor assembly for a mine roof bolt or the like in which the bail of an anchor  shell  having leaves for engaging the  side wall of a bore hole has spring fingers for snagging the side wall of a bore hole to prevent downward movement to the anchor shell. The bail has a central opening for the roof bolt to pass through with the central  opening having projections  that extend inwardly of the opening to form an interference fit with the threads of the bolt as it is rotated through the opening. The leaves of the anchor shell which  are clamped against the side wall have surfaces which diverge from tapered surfaces of the plug nut for expanding the anchor shell to prevent plowing between the plug nut and anchor leaves. The surfaces on the leaves extend downwardly from the top to about the bottom of the leaves.

Abstract: METHOD OF AN APPARATUS FOR OPENING A FOLDED WEB OF HEAT-SEALABLE PACKAGING MATERIAL PRIOR TO FORMATION     OF THE WEB INTO SEALED RECLOSABLE PACKAGES          Abstract of the Disclosure A method of opening a folded web of flexible heat-sealable packaging material prior to formation of the material into sealed reclosable packages.  The web has a pair of interlockable reclosable closure strips extending longitudinally of the web on an inside face of the web, and one section of the web is folded over on another section of the web so that the closure strips are interlocked.  The method comprises advancing the folded web in a first plane to a web-opening station, and opening the folded web while maintaining the closure strips interlocked as the web advances  through the web-opening station.   The web is opened by diverting both sections of the web relative to one another so that they assume a co-planar position in a second plane different from the first plane.

Title: Automated evaluation of painted surface quality
Inventor: CHANG DAVID B
IPC: G06T1/00
Filed: 1991-10-22
Abstract: AUTOMATED EVALUATION OF PAINTED SURFACE QUALITY                 Abstract of the Disclosure Human aesthetic evaluation of a finished painted surface, such as an automotive body, is automatically simulated by analyzing a distorted reflected test pattern from the finished surface.  Fourier power spectra of the distorted test pattern are generated to form a parameterization of the reflected distorted test pattern.          A correlation is statistically made to reference Fourier power spectra, each of which has been associated with a specific human aesthetic evaluation, such as wetness, dullness, softness, brightness, and the like.  The Fourier power spectra of the distorted reflected image are automatically generated through a digitized two dimensional pixel map, which are mapped into functions of the edge direction and edge intensity of the pixels.  The functions are then Fourier transformed into Fourier power spectra and correlated with reference reflected patterns.          Alternatively, the Fourier power spectrum of the distorted reflected pattern is optically generated by use of collimated coherent light in a Fourier transform lens.          After that, the necessary parameterization is extracted from the optical Fourier transform plane and correlated to previously recorded aesthetic human evaluation.  A segmentation parameter is also used for correlation with a reference segmentation indicator.

Title: Method of and measuring arrangement for contactless on-line measurement

Filed: 1992-05-05
Abstract: Abstract of the Disclosure With an infrared radiator, the surface temperature of which is kept constant during measurement, a measuring area  on  a  roughened  material  surface  is  thermally irradiated with oblique incidence of the rays.   The temperature of the reflected thermal radiation is mea-sured by an infrared thermometer, which is arranged above the measuring area in such a way that the reflected radiation falls into the area of coverage of the infrared thermometer. The entire measuring area of the material surface which lies  in the field of coverage of the infrared thermometer must be thermally irradiated. The measured temperature variation of the reflected radiation in dependence on the known surface roughness of the material is stored in a comparison device. This com-parison device is fed a set value for the desired surface roughness.  The  infrared  temperature  of  a  material surface, initially unknown with respect to its surface roughness,  is measured and compared with the stored temperature variation, in order to determine the magni-tude of the surface roughness.   From the value thus obtained and the set value fed in, a differential signal is formed, which is fed via the output of the comparison device to a control  of a treatment device for the material.
