Patent number: 6616874Abstract: A method forms a concrete block, particularly but not exclusively a composite block with a reflective fascia portion. The block is formed by a dry-cast technique, in which mixture for forming the block has a water/cement ratio less than or equal to 0.35, in combination with application of a compaction force so that the resultant block complies with compressive strength requirements set out in BS 6717: part 1: 1993.Type: GrantFiled: July 20, 1998Date of Patent: September 9, 2003Inventor: Michael Lazar

Patent number: 6604281Abstract: A packaging process of a circuit board involves a first step in which the circuit board is provided with a predetermined number of pins and is then arranged in the lower mold of a first molding tool. The upper mold of the first molding tool is joined with the lower mold before the resin is injected. The mold is then opened to remove therefrom a semifinished product, which is provided with a metal passivation layer and is subsequently placed in a second molding tool to carry out a second packaging operation. The second molding tool is opened to remove therefrom a finished product.Type: GrantFiled: July 11, 2001Date of Patent: August 12, 2003Assignee: Power Mate Technology Co., Ltd.Inventor: Dennis Shiau

Patent number: 6596208Abstract: An automated process for manufacturing rubber paving blocks uses crumb rubber recovered from used automotive tires. A production line in which the molds are emptied of the formed rubber paving block and then filled with a fresh crumb rubber mixture is balanced with an oven line in which the compressed crumb rubber mixture is heated, cured and cooled before being returned to the production line for further processing. The mold includes a lid having latching mechanisms that are actuated by compressed air. The formed rubber paving block is removed from the cooled mold through a compressed air extraction mechanism so that the formed block is not damaged during the extraction process. The rubber paving block is formed with a textured bottom surface having a central depressed disk and a plurality of grooves forming interconnected passageways for water to pass beneath the blocks when installed.Type: GrantFiled: February 6, 2001Date of Patent: July 22, 2003Inventors: Moses B. Glick, Stephen S. Stoltzfus, Monroe Z. Stoltzfus

Patent number: 6572802Abstract: A novel process for creating aesthetically pleasing multicolor designs and patterns in cast materials, particularly cementitious materials, which may be used to imitate natural stone in appearance. The process includes the steps of preparing multiple colors of the casting material, geometrically loading these colors in a three dimensional array in a holding container according to formulas corresponding to particular patterns to be created, placing the geometrically loaded colors into a mold by means which include pouring, extruding and spraying, consolidating the mixtures in the mold and allowing them to set, and removing the cast structure from the mold followed by polishing and sealing if required. A removable matrix in the holding container provides the ability to reliably repeat patterns according to the loading formulas.Type: GrantFiled: June 14, 2000Date of Patent: June 3, 2003Assignee: The Spectrastone Co. International, Inc.Inventor: Mark Austin

Publication number: 20030047832Abstract: Apparatus for manufacturing a multicolor slide fastener includes an upper die 110, a lower die 120, and a plurality of unit fastening teeth-forming slots 101 formed in a lengthwise direction. Molding material-injecting passages and a plurality of sprue holes 102 are provided for injecting the molding materials S into the slots 101. Inclined passages 201 and 202 are connected to the molding material injecting passages respectively, for carrying the molding materials S from a raw material source. Heaters 240 and heat sensors 241 heat the passages 201 and 202. Pressing means 300 press the molding materials S into the inclined passages 201 and 202. Valves 400 control injection of the molding materials S into the sprue holes 102 of the upper die 110.Type: ApplicationFiled: August 14, 2002Publication date: March 13, 2003Inventor: Young-Chul Kang
