Patents by Inventor Marcel Riendeau

Marcel Riendeau has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20200033076
    Abstract: Methods, plate elements and heat/enthalpy exchangers, a) perforating an unformed plate element with defined outer dimensions in any desired area and in any desired dimension; b) covering at least one side of the unformed plate element with a thin polymer film with latent energy exchange characteristics and; c) forming the plate element into a desired shape and a pattern of corrugations and/or embossing. The operations b) and c) may be performed in a different order. For instance, when the plate element is made out of plastic, b) may be performed before c) whereas, when the plate element is made out of aluminum (or plastic), c) may be performed before b). Operations a) and/or b) and/or c) may also, in certain embodiments, be combined.

  • Patent number: 10041746
    Abstract: Enthalpy exchanger elements which allow the creation of enthalpy exchangers whereby the efficiency of sensible energy exchange and latent energy exchange can be varied and controlled and especially improved. Also, a method for the production of enthalpy exchanger elements including: ?a) perforating a flat plate element (1) according to a predetermined perforation pattern (2, 2, . . . ) within the plate outer dimensions, or providing a plate element (1) with an inherent pore structure; ?b) applying to at least one side (1a) of the plate element (1) a thin polymer film (3) with water vapor transmission characteristics; ?c) forming the plate element (1) into a desired shape exhibiting a corrugation pattern (4, 4, . . . ), whereby the polymer film (3) is formed into the same corrugation pattern shape as that of the plate element (1).
