Patent CA-2007805-A1 (CA)
Inventor: ELEPANO NORMITA P
IPC: C09K3/14
Filed: 1990-01-16
Abstract: This invention relates to a buffing composition, and, in particular, to a composition that imparts a very fine finish to automobile surfaces. In the 1980's, automobile manufacturers began using a base coat/clear coat paint system for automotive surfaces. The base coat imparts the desired color, and the clear coat, which is applied over the base coat, is a transparent, hard, chip-resistant, protective coat. This paint system magnifies painting defects in either the base coat or the clear coat. If the defects cannot be corrected on the assembly line, the automobile must be removed from the line, the defects removed, and the automobile then repainted. This procedure results in a considerable loss of time, and consequently, money for the automobile manufacture. A system, known as the "Finesse-it" system, has been developed for removing paint defects on the assembly line.      The system first utilizes a sanding step, employing very fine coated abrasives, to smooth out the defect. Next, the defect is buffed with "Finesse-it" brand finishing material to remove the scratches produced by the coated abrasives. Finally, the residue from the finishing material is removed with a cotton cloth, thereby producing a uniform, glossy finish. The "Finesse-it" finishing material tends to leave a milky haze on the painted surface where the defect was repaired. It would be desirable to use a buffing composition that does not produce haze marks, so that paint defects can continue to be removed on the assembly line. This invention provides a buffing composition for imparting very fine finishes to automobile surfaces that contains no silicone-containing materials and comprises alumina abrasive and a synthetic wax dispersed in a liquid medium. The liquid medium can be a solvent, water, a hydrocarbon oil, or mixtures thereof. The buffing composition can optionally contain other additives or modifiers such as wetting agents, thickeners, stabilizers, preservatives, emulsifiers, dyes, pigments and perfumes.

Title: Drying and heating of polyamide granules
Inventor: TISCHENDORF KLAUS J
IPC: B29B13/06
Filed: 1990-07-11
Abstract: - 9 -         O.z. 0050/40940 Abstract of the Disclosure: Polyamide granules are dried and heated (for solid-phase postcondensation) by feeding a suspension of granules in water into a sieve means (1), where the bulk of the water is removed, and then into a tower dryer (10), where they are deposited in bed form and then freed of the remaining water while moving in plug flow under the force of gravity with a counter-current inert gas stream at from 70 to 200°C. The tower dryer possesses an inlet at the top (11) and outlet at the bottom (34) for the granules and also feed lines (20, 22, 31) for the inert gas. To achieve a uniform degree of drying of the granules, the inert gas is divided on entry into the tower dryer at a point between the drying zone and the heating zone into a stream which flows radially inward into the bed of granules on the one hand and a stream which flows radially inward and outward on the other. In this way the inert gas is distributed particu-larly uniformly and the granules are dryable in a very short drying zone down to a water content of 0.0001 kg of water/kg of polymer. The lower, conically tapered area of the tower dryer - bin 30 - ensures a uniform rate of descent of the granules and hence a uniform solid-phase condensation with a favorable molecular weight distribu-tion. The granules may be heated to temperatures close to the  softening point  of  the polymer.  In addition,  a further stream of inert gas may be passed through the conical bin.  The tower dryer  (10)  is  followed by a fluidized bed cooler  (41)  in which the granules are cooled with air to <50°C.

Patent CA-2026027-A1 (CA)
IPC: B41F13/04
Filed: 1990-09-24
Abstract: ABSTRACT OF THE INVENTION    A device for embossing a set of motifs having a predetermined motif interval onto a length of film utilizes a rotating embossing cylinder which is provided with a recess for the attachment of an embossing matrix.  The embossing matrix has a usable length which is less than the entire circumference of the embossing cylinder hut more than 50% of the circumference of the embossing cylinder.  A rotating counterpressure cylinder is positioned adjacent the embossing cylinder, such that the film advances between the counterpressure cylinder and the embossing cylinder for embossing said motifs from said embossing matrix onto the film and for defining a free phase during each rotation of the embossing cylinder when the recess is positioned adjacent the film.  The device also comprises movement means for providing an additional relative movement between the length of film and the embossing matrix during each free phase of the embossing cylinder.  A control mechanism determines the amplitude of the additional relative movement in accordance with the motif interval.  It is a significant advantage of the present invention that the embossing cylinder circumference is independent of the motif interval thus allowing for easy change of the embossing matrix.

Title: Carpet cutting tool
Inventor: MACDONALD LEA H

Filed: 1990-10-03
Abstract: CARPET CUTTING TOOL ABSTRACT OF THE DISCLOSURE A carpet trimming tool is disclosed for trimming edges of two carpet sections to be placed into abutment and joined together by a thermo adhesive tape or the like.  The device utilizes a base with a pair of transversely spaced, upwardly projecting blades cooperating with a downwardly directed clamping arrangement holding the two carpet sections in engagement one with each of the two blades.  Since the two blades cut the respective carpet sections from the underside generally cutting only the base of the carpet, and due to the constant spacing between the two blades, the resulting joint is virtually entirely concealed as there is no damage to the tuft caused by the cutting.
