Patent number: 10926375Abstract: A pressure-fit grinding pad assembly and a method of constructing same and connection to a grinding pad of a floor grinding machine or other suitable type grinding machines is described. The grinding pad is formed by an abrasion head of abrasion material which is immovably bonded on a metal attachment base which is shaped for pressure fit connection to a mounting base and wherein its removal therefrom requires it to be pressure punched with adequate force. The mounting base can be a steel plate shaped for connection to retainers secured to or formed in an outer surface of a grinding disc or may be constituted by holes formed in the top surface of the grinding disc. The mounting base can be formed integrally with the attachment base of the grinding pad for connection to the retainers.Type: GrantFiled: June 20, 2018Date of Patent: February 23, 2021Assignee: GESTION ANNY PICARD INC.Inventors: Luc Laforest, Mario Fréchette, Sébastien Fortin

Patent number: 8381527Abstract: The present specification generally relates to improvements to combustors such as burners and engines. In one aspect, the specification presents an acoustically enhanced ejector system which can be used as part of an intake system for a combustor. In another aspect, the specification teaches the use of a combustor combustion chamber as an oscillator to magnify a harmonic frequency of a pulsating frequency of the combustor. In still other aspects, the specification presents a combustion chamber having an inlet with a plurality of tangentially spaced apertures, and an in-line intake system connected to the apertures.Type: GrantFiled: November 23, 2011Date of Patent: February 26, 2013Assignee: Atlantis Research LabsInventors: Luc LaForest, Dennis Vivian Collins
