Jeremi Maciejewski 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).

  • Patent number: 5580917
    Abstract: Hydrostatically damping, shock and vibration energy absorbing, non-vulcanisable silicone elastomer is composed of a methylphenylsilicone polymer in which as on the matrix a condensation of polydimethyl- or/and methylhydrosiloxane diols are condensed with reactive compounds of silicon, boron or nitrogen giving the viscous polymer appropriate elasticity coefficient by forming mobile hydrogen bonds. The elastomer according to the invention contains also fillers and lubricants.

  • Patent number: 4307794
    Abstract: This invention relates to an apparatus for absorption of mechanical energy, particularly energy of very strong shocks. It comprises an immobile cylinder and, inserted in it in telescopic fashion, a mobile part consisting of at least one mobile cylinder with a bottom and a mobile plunger inserted into the last cylinder, the empty space between the cylinders and between the last cylinder and the plunger being filled with a medium absorbing energy of shocks and vibrations and being characterized by viscous flow in static state and by high elasticity in dynamic state. Any of the mobile cylinders is provided with a plunger and a baffle dividing the cylinder into two chambers, one chamber being filled with a visco-elastic medium absorbing mechanical energy, and the other chamber being filled with a visco-elastic medium compressed to a pressure higher than 1000 h Pa.
