  • Publication number: 20260055029
    Abstract: Dispersion-based ready-to-use grout formulations, methods of making such dispersion-based ready-to-use grout formulations, and the resultant grout products that perform as reactive resin grout products. The grout formulations of the invention at least include a water-based acrylic polymer dispersion binder and optionally a water-based acrylate copolymer dispersion binder, in combination with one or more of an alkaline cross-linker, one or more silane adhesion promoters and/or a micro-fiber filler, along with various other constituents, to provide one-part ready-to-use grout formulations that require no mixing prior to use thereof. The resultant grout products of the invention meet performance standards of epoxy grout products, without requiring mixing of composition parts and without any adverse side effects.

  • Patent number: 12473429
    Abstract: Two-component epoxy-based liquid formulations and their resultant dual use epoxy-based products. The epoxy-based liquid formulations include a liquid epoxy resin composition mixed with a liquid epoxy curing agent composition. The liquid epoxy resin compositions include one or more liquid epoxy resins containing a reactive oxirane structure or epoxide group, while the liquid epoxy curing agent composition comprises one or more epoxy curing agents. The liquid epoxy resin and liquid epoxy curing agent compositions are mixed together to provide a dual functioning epoxy-based formulation that, when applied to a substrate and cured, provides a cured three-dimensional cross-linked thermoset dual acting epoxy-based product having both the moisture vapor barrier and the primer functionalities.

  • Publication number: 20050254597
    Abstract: A transmit circuit reduces undesired amplitude modulation (AM) in transmit signal pulses by substituting predetermined amplitude information for actual pulse amplitude information during portions of the pulse corresponding to nominally constant amplitudes. For example, GMSK and certain other modulation formats use a desired transmit pulse shape that includes a nominally flat middle portion. An exemplary AM reduction circuit detects generated pulse values corresponding to the nominally constant-amplitude portions of the transmit pulse and substitutes predetermined, preferably constant, amplitude values in their place. As such, the circuit may include a comparator used to detect the pulse values corresponding to variable amplitude portions of the pulse, which it passes through, and to detect those amplitude values corresponding to constant-amplitude portions of the pulse, which it replaces with substituted values. Such operation may include amplitude value filtering, and such operations may be modal, e.g.

  • Patent number: 4568498
    Abstract: The reaction of the lithium enolate of acetaldehyde, LiOCHCH.sub.2, with achlorocyclotriphosphazene, N.sub.3 P.sub.3 Cl.sub.6, lead to the series of (vinyloxy)chlorocyclotriphosphazenes, N.sub.3 P.sub.3 Cl.sub.6-n (OCH.dbd.CH.sub.2).sub.n (n=1-6). The nongeminal pathway is favored. These materials undergo homopolymerization reaction and can be copolymerized with a wide variety of organic monomers. The resulting polymeric systems incorporate certain properties such as fire retardancy and are chemically bonded to the polymer rather than an additive.
