Patent number: 8464491Abstract: A system of blocks is configured to be compatible with each other in the construction of a columnar structure. Each block has four faces and all four faces may generally have the same dimensions. The width of the blocks may generally be about twice their height. The faces of the block also may contain a slot to add an aesthetic appearance to the column. The blocks have certain constructions features that mate with specially constructed brackets in attaching a fence panel to the completed column. The blocks have interlocking elements or projections that permit positive connection between courses of blocks. Projections of one block extend into the core another block. Adjacent blocks can be rotated 90 degrees relative to each other about a vertical axis of each block with each course. The blocks can be used to construct a column that is easy to install and structurally sound.Type: GrantFiled: November 23, 2009Date of Patent: June 18, 2013Assignee: Keystone Retaining Wall Systems LLCInventors: Robert A. MacDonald, William B. Dawson

Publication number: 20120131873Abstract: A method of making a wall block and a mold box therefore. The wall block design maximizes the use of the mold box. The method produces wall blocks having a large surface area front face compared to the front face size of prior art blocks. The blocks have about one third more front surface area. This results in faster construction of walls and a faster construction sequence. The method of making the blocks makes efficient use of mold space and material, resulting in higher production yields and/or higher total daily production square footage.Type: ApplicationFiled: February 7, 2012Publication date: May 31, 2012Applicant: KEYSTONE RETAINING WALL SYSTEMS, INC.Inventors: William B. Dawson, Robert A. MacDonald

Publication number: 20080172970Abstract: A system of columnar blocks and stacking blocks interlock with each other in the construction of a pilaster or column and a fence panel, respectively, for use in a fence. The columnar blocks are generally square and the stacking blocks are generally rectangular. The columnar block faces may contain one or more slots to give a column an appearance of a masonry joint. Blocks have at least one interlocking element that permits a positive connection between courses of the blocks when the interlocking element is received in an overlying block.Type: ApplicationFiled: March 27, 2008Publication date: July 24, 2008Applicant: KEYSTONE RETAINING WALL SYSTEMS, INC.Inventors: Robert A.

Patent number: 6147309Abstract: A communications cable having superior electrical characteristics and meeting the burn requirements for plenum applications has a core formed of one or more twisted wire pairs having primary insulation formed of a suitable material, such as high density polyethylene. The core is surrounded by a single outer jacket formed from a material having excellent heat/flame resistance characteristics and acceptable electrical characteristics that are substantially stable at relatively high temperatures, such as a foamed thermoplastic halogenated polymer, for example polyvinylidene fluoride material. The electrical conductors utilized by the cable are oversized (relative to conventional 24 gauge conductors) to enhance the electrical performance of the cable. An air gap formed between the conductor core and the outer jacket further enhances the electrical performance of the cable.Type: GrantFiled: October 25, 1999Date of Patent: November 14, 2000Inventors: John J. Mottine, Kenneth S. Koehler, Sayed J. Mirkazemi, William B. Dawson
