Abstract: The present invention relates to a micro-interface strengthening reaction system and method for heavy oil hydrogenation preparation of ship fuel, including a liquid phase feed unit, a gas phase feed unit, a micro-interface generator, a fixed-bed reactor and a separation tank. The present invention may reduce the pressure during the reaction by 10-80% while ensuring the efficiency of the reaction by breaking the gas to form micro-sized micro-bubbles and making the micro-bubbles mix with heavy oil to form an emulsion to increase the area between the gas and the liquid phase and to achieve the effect of enhancing mass transfer in a lower preset range. And, the present invention greatly enhances the mass transfer, so that the gas-liquid ratio can be greatly reduced. Also, the method of the present invention has low process severity, high production safety, low product cost per ton, and strong market competitiveness.

Abstract: Training accessories and methods for improving athletic techniques, such as, for example, tackling form for football. A display can be coupled to a piece of athletic equipment, such as a tackling dummy, and the display depicts a symbol at a time at which a player is or is about to interact with the equipment or perform a movement or action. An input is provided of the player's identification of the depicted symbol and compared to the symbol that was actually depicted. The player's correct identification of the depicted symbol can indicate that the player performed the movement or action, or the interaction with the equipment, with appropriate form. A player's failure to correctly identify the depicted symbol can indicate to a coach that the player may need further instruction on proper technique or form with which the movement or action, or the interaction with the equipment, should be performed.

Abstract: A continuous steady state flow process for converting proteinaceous materials by reacting the proteinaceous materials with coagulants or other precipitants in situ. Streams of proteinaceous materials and coagulants are fed into an introduction chamber under a predetermined pressure and are directed through an orifice as a high velocity jet stream into a resonance chamber to impinge against a vibratile element. The energy from the jet stream is transferred to the vibratile element to cause it to vibrate at high sonic or ultrasonic frequencies. The high sonic or ultrasonic energies are transferred to the mixture of proteinaceous materials and coagulants to produce a cavitational effect and cause instantaneous reaction and homogenization of the proteinaceous materials and coagulants to thereby form a protein matrix.
