The present invention is related to finishing mechanical, electronic, and jewelry workpieces. The system comprises a container -including an abrasive medium-, a control unit, a measurement unit, and a display. Adjusting the rotational and vibration motion is conducted using magnetic coils and eccentric weights in the control unit. Moreover, the control system can tune the container's tilt angle. The magnetic coils enclose the container producing a magnetic field, thereby pulling the abrasive particles against the target surfaces. The container is held by two motors located at its top and bottom, which provide the rotational movement of the container around its axis. Besides, the rotary motors that hold the container are bound by the structure related to the vibration motors, which are paid by the vibration motors of the container assembly and the materials inside it due to the resulting vibration. Finally, these motors are placed on the device's frame with the help of a vibration damping system (springs), which allows the device to be adjusted at different tilt angles and create a rocking motion with the help of an angular movement mechanism. The printing circuit companies, ornamental jewelry companies, and factories producing mechanical parts are potential customers of this equipment that can use this machine for surface finishing aiming to increase the surface smoothness on a micro scale for a large number of parts.

The invention is a prosthetic leg for above-knee amputees that helps prevent tripping and provides support for strenuous movments. The design harvests energy from walking to further lift the foot and decrease the risk of tripping. The invention also harvests energy during the sitting motion and uses it to power the leg when the user stands up.

The prosthesis is unpowered and lightweight, with polycentric joints and a single pneumatic actuator. The actuator harvests, stores, and releases energy in both tension and in compression and is biarticular, allowing it to power both the knee and the ankle. The invention's unique geometry allows it to exert forces at the joints that can mimic the muscle forces produced in a healthy leg during specific movments. The technology is currently designed to mimic leg forces during sitting and standing, but could also be tuned to mimic leg forces of other movements. While walking, the invention harvests energy from the leg's momentum and uses it to lift the foot higher off the ground during swing, increasing toe clearance. This decreases the chance of tripping and greatly increases walking safety, especially among the elderly and impaired who fall more frequently and can sustain serious injureies from a fall. The combination of these two functions makes the invention ideal for low-mobility prosthetic users.

The invention is currently at TLR 3, and the authors are seeking commercial partners who are interested in continuing the invention's development and bringing it to market, or who would wish to implement this technology under a license.

This invention describes an apparatus that enables the automated removal of small samples from fluids such as those encountered in (bio-)chemical reactors. These samples can then be used for, e.g., kinetic analysis and quality control applications. The system was explicitly designed to be compatible with harsh and aggressive reaction conditions and can be used up to 250°C and 345 bar. The system was incorporated into a high-pressure capable operando reaction analysis platform that enabled simultaneous sampling of the reaction mixture and operando monitoring of the reaction using multiple channels of spectroscopy, thereby offering accessible and convenient data-rich experimentation. We have started a company to further develop the technology and bring it to market. We are actively looking for early adopters, collaborators, joint-venturing, and investors.

H₂S and CO₂ are two well-known emissions with cumbersome management and not yet established bulk utilization plans. The invention converts H₂S and CO₂ in syngas and, as the only by-products, elemental sulphur and water by means of a dedicated (i) Regenerative Thermal Reactor (RTR) and (ii) Acid Gas to syngas (AG2S) process layout thanks to the overall reaction: 2 H₂S + CO₂ = H₂ + CO + S₂ + H₂O. The reaction is globally endothermic, but it can energetically supplied in situ thanks to a minor injection of oxygen/air. The oxygen injection generates the exothermic reaction S + O₂ = SO₂ in an appropriate amount so as to achieve and preserve the optimal conversion temperature. The SO₂ generated for energy sustainability is therefore converted within the process layout. The once-through conversion is 75%v for the H₂S and 50%v for the CO₂. The unreacted reactants are split from the syngas and by-products and recycled upstream for complete conversion. The invention is the first process utilizing no sources, neither bio nor fossil, but only emissions to generate syngas and, hence, hydrogen. Two moles of syngas are obtained every three moles of emissions, also achieving the total neutralization of H₂S and a relevant cut of CO₂. Technology development has reached out the industrialization level. The laboratory testing has been developed in Politecnico di Milano, at the facilities of the Center for Sustainable Process Engineering Research (SuPER); the bench-scale tests have been exerted at the Sotacarbo Sustainable Energy Center SpA facilities and the industrial application is just started at Itelyum Regeneration srl, an ecorefinery for exhausted oil recovery.
