Abstract: Hybrid ventilation apparatuses, systems and methods are provided. Some example mechanical ventilation apparatuses include a gas delivery system, at least one oxygen concentrator for generating oxygen enriched gas for delivery to a patient, at least one pressurized oxygen source for providing oxygen for delivery to the patient, and a controller. Based at least in part on an FIO2 setting for the gas to be delivered to the patient, the controller may determine an oxygen enriched gas flow rate of the oxygen enriched gas and a pressurized oxygen source flow rate of the oxygen from the at least one pressurized oxygen source, for the gas to be delivered to the patient. The controller may control the gas delivery system to deliver the gas to the patient in accordance with the FIO2 setting, the determined oxygen enriched gas flow rate, and the determined pressurized oxygen source flow rate.

Abstract: A product switching mechanism, located downstream of a rotary shear for rod and bar product, includes first structure defining a horizontally elongate chamber with a top, bottom and one side wall, the chamber being open at the side opposite the one side wall, the chamber having one end remote from the rotary shear and another end adjacent the rotary shear with the one end being open; a second structure defining a substantially flat vertical surface closing the open side of the chamber and providing first and second substantially horizontal passages; the first passage is enclosed above, below and on either side and has a downstream opening and an upstream opening, the second passage having an upstream opening vertically adjacent the upstream opening of the first passage, the second passage opening through the surface of the second structure and having a side wall angling toward the surface as it extends away from the upstream opening of the second passage, so that product entering the upstream opening of the s

Abstract: Guide devices are mounted on an apparatus which can be affixed to and supported by a frame such as an uplooper frame. The apparatus includes an entry guide mounted to the frame and supporting a slide bar with a horizontal top edge extending parallel with but displaced from the pass line. A guide box carriage is movably secured to the slide bar and a guide box is supported by the guide box carriage. A bell mouth carriage is also removably secured to the slide bar between the guide box carriage and the frame, with the bell mouth assembly being manually and removably secured to the bell mouth carriage. All major portions can be removed or put into place quickly with the aid of an overhead crane.

Abstract: The disclosure herein pertains to the preparation of N-(alkoxymethyl)- and other N-methylene ether-substituted 2-haloacetamides from other N-methylene ether-substituted 2-haloacetamides and the appropriate alcohol by a transetherification process.
