Abstract: A conveyor scraper includes a support structure and a scraper blade which is mounted to the support structure by a mounting element so that it is movable to a limited extent relative to the support structure. A biasing element acts between the support structure and the scraper blade to ensure contact with an adjacent conveyor. A mounting element that mounts the scraper blade to the support structure includes a zone of weakness that permits the scraper blade to deflect laterally in the event of impact by an irregularity on the passing conveyor belt surface.

Abstract: A blow molded plastic container for carbonated beverages includes an upper mouth-forming portion, a cylindrical sidewall portion and a lower base-forming portion, all of the portions being generally symmetrically situated about a central longitudinal axis. The lower base-forming portion includes a central portion contiguously surrounding the central longitudinal axis and a plurality of circumferentially-spaced, downwardly convex rib segments, each rib segment extending upwardly from the central portion following a hyperbolic profile and expanding circumferentially outwardly to merge with the sidewall. The lower base-forming portion additionally has a plurality of intervening and circumferentially-spaced, convex, hollow foot-forming portions extending downwardly from the circumferentially-spaced, rib segments. Each of the foot-forming portions has a bottom clearance-forming portion adjacent the central portion and a lower outer portion defined by the rotation of a heel radius greater than 0.

A harmonic drive unit including a housing is fixed to an end of the hollow spindle, the housing containing a circular spline fixed to the housing. The harmonic drive unit also includes a flexspline gear ring situated within and engaged with the circular spline, the flexspline gear ring being fixed to the shaft situated within the hollow spindle. The harmonic drive unit also includes a wave generator positioned within the flexspline gear ring for displacing the flexspline gear ring with respect to the circular spline. A brake rotor is coupled to the wave generator.

Abstract: A method as well as a respective apparatus for lining pipes and ducts are suggested, wherein a flexible tube is introduced in turning up manner into a pipe having respective openings at the pipe access end and the pipe terminal end. Here, prior to the turning up operation, a traction means is led through the flexible tube and the pipe and is secured to the flexible tube access end, wherein the flexible tube with the terminal end of the flexible tube is joined to the pipe access end and the traction means is automatically or distance-controlled pulled from the pipe access end by means of a motor winch. Here, the pipe by using turning up the flexible tube is lined therewith. The method is particularly suited for lining pipes and ducts having a plurality of pipe bends or angles.

Abstract: It is described a method for lining a pipe or a duct through an internal lining of a plastic coated flexible fabric tube adhering to the inner wall of the pipe by means of an adhesive. This method stands for the following steps:filling a metered amount of adhesive into said flexible fabric tube in a uniform distribution over the flexible tube length,introducing said flexible fabric tube into the pipe, wherein one end of said flexible tube is fastened to the rear pipe end with respect to the moving direction, and the flexible tube using turning up is introduced into said pipe, andgenerating an internal pressure inside said introduced flexible fabric tube by means of supplied water for pressing said flexible tube against the inner wall of said pipe until the adhesive between said flexible tube and the inner wall of said pipe is cured. Here, the water is heated and cooled in controlled manner depending on the temperature values measured inside and outside the pipe for accelerating the curing operation.

Abstract: The present invention relates to processes and products made of a natural component being cashew nut shell oil (CNSO) and another component being di- and/or polyisocyanates. Since the CNSO is a mixture of a biphenol and a fatty acid, both of which have a benzenoid ring with phenyl radicals and side chains, one of which has three double bonds, the isocyanates can react on three different levels:I. The COOH of the fatty acidII. The OH of the phenyl radicalsIII. The double bonds of the chains.

Abstract: A cap for dispensing material from a container defining an interior portion, including a housing capable of attachment to the container and including a translucent region, and defining an aperture, a first opening, and a second opening, and a spout member disposed through the aperture and defining a transfer compartment, having a first end and a second end and defining an inlet orifice at the first end and an outlet orifice at the second end, the spout member rotatably movable with respect to the housing between a first position where the inlet orifice is disposed to generally align with the first opening and communicate with the interior portion and the outlet orifice is disposed within and closed by the housing whereby material within the container may be transferred from the interior portion into the transfer compartment through the inlet orifice but material may not be dispensed from the container, and a second position where the inlet orifice is disposed within and closed by the housing and the outlet or

Abstract: The invention relates to a method for coloring pieces of rock, namely marble, by means of the application of a laser beam (2) in order to color-mark or totally color the piece of rock. According to the invention, the laser beam interacts with the piece of rock (5), to which an appropriate coloring is subsequently applied. Diffusion of the pigment in the piece of rock changes its color in the area affected by the laser. The piece of rock takes on the color as intensely as desired. The invention enables marble of a lower value to be made more valuable and increases the value of other rocks and allows them to be colored. This application is mainly intended for the treatment of ornamental rocks.

Abstract: The invention relates to a method and an apparatus for lining a pipe through a sealing internal lining by using a flexible tube including adhesive, which is introduced into said pipe in turning inside out manner and is kept dimensionally stable until the adhesive is cured. To reduce the frictional force during the introducing operation a strip additive is deposited onto the outside of the flexible tube prior to the turning up operation. A strip additive having a gel-like consistence is used to minimize the frictional force. For a uniformly wetting the flexible tube with the strip additive, this is transferred into a liquid condition by heating prior to depositing. After depositing, it quickly cools down to the ambient temperature such that the required gel-like consistence is ensured for the introducing operation. Thereby it is possible to line pipes or ducts comprising several pipe bends an angles within the line course.

The container includes a handle portion which can have an indented portion disposed proximate to the storage compartment. The storage compartment defines an opening disposed generally opposing the bottom surface, and the measuring dispensing compartment includes volumetric indicia and defines a dispensing orifice disposed generally proximate to the bottom surface. At least a portion of the container proximate to the measuring dispensing compartment is formed of a visually translucent material.
