Latest Patents

One of Wojciechowski's latest patents is for a "Gate with Counterweight and Lowering Exchangeable Span." This invention features an exchangeable span that is fixed to a load-bearing beam and is connected with pulley bearings and rope-slings to a system of adjustable counterweights. The drive system includes an electric drive with a worm-wheel mounted to the load-bearing beam, which travels vertically along the worm. The entire assembly operates on adjustable guiderails within a reinforced concrete pit, allowing for efficient movement in the opposite direction of the counterweights. Additionally, the gate can be operated manually in emergencies by using a crank handle connected to the worm.

Another significant patent is for the "High Pressure Synthesis of Sulfur-Selenium Fulvalenes." This process enables the one-step preparation of sulfur-selenium fulvalenes through the reaction of an acetylenic compound with carbon selenide sulfide or a mixture of carbon diselenide and carbon disulfide under extreme pressures of at least 1,000 atmospheres. The resulting fulvalene compounds contain at least one sulfur atom and one selenium atom in their ring structure. This innovative process also produces substituted diselenadithiafulvalenes, which serve as precursors to very pure diselenadithiafulvalene, useful in the preparation of charge-transfer salts.
