Title: Alvah A. Lawrence: Innovator in Cable Protection
Introduction
Alvah A. Lawrence is a notable inventor based in Los Altos, California. He has made significant contributions to the field of cable protection, holding a total of 3 patents. His innovative designs focus on preventing damage to cable splices, ensuring the integrity and longevity of electrical systems.
Latest Patents
One of his latest patents is titled "Cable Blocking and Block Splice Protection." This invention relates to an assembly of a splice between a cable containing paper insulation and a cable containing oil or petroleum-based materials. The splice, or at least the end of the cable containing the oil or petroleum-based material, is encapsulated in a particulate material such as calcium carbonate and placed under compression. This design prevents the oil or petroleum-based material in one cable from migrating into the splice area or into the other cable, thereby protecting the paper insulation. Additionally, the assembly prevents the migration of water from either cable into the splice area.
Another significant patent is "Protection of Cable Splice." This invention protects a splice between two multiconductor cables from the ingress of water. It features a closure filled with a sealant, which is pressurized by a bladder inside the closure. The pressure is sufficient to force the sealant into the interstices of the splice and the interstices between the conductors in the cable. The pressure is maintained by the bladder until the sealant cures or hardens, ensuring a robust seal against moisture.
