Patent number: 11448073Abstract: Accordingly, embodiments herein disclose a system (500) for controlling admission volume of an inlet gas for fixed RPM operation of in an apparatus. The system (500) has a boiler (502) for generating a steam at a higher pressure for heating application in a process. A pressure reducing valve (PRV) (504) controls a boiler pressure to process pressure. Inlet ports and exhaust ports are configured by intersection of opening on a rotor housing (614) and opening on a rotating valve. Inlet ports are configured so that a port opening duration can be controlled to admit required volume of a steam corresponding to a mass flow requirement of the process. A port capable of changing the area and timing of opening in such a way that the duration and starting of exhaust can be controlled.Type: GrantFiled: October 3, 2019Date of Patent: September 20, 2022Assignee: Indian Institute of Technology, Madras (IIT Madras)Inventors: Vipin Venugopal, Satyanarayanan Seshadri

Patent number: 9452271Abstract: A nebulizer assembly configured for removable attachment to an ultrasonic actuator includes a base plate portion, a porous mesh member, and a cover member. The base plate portion includes an opening extending therethrough, and is substantially rigid such that ultrasonic vibrations from the ultrasonic actuator may be transmitted through the base plate portion to the porous mesh member to vibrate the porous mesh member. The porous mesh member is configured for passage therethrough of a nebulized fluid, and is disposed in the opening of the base plate portion proximate a fluid emission side of the nebulizer assembly. The cover member is disposed on a second side of the nebulizer assembly opposite the fluid emission side. The cover member covers the opening and defines a cavity between the cover member and the porous mesh member. The cavity is configured to retain a fluid to be nebulized.Type: GrantFiled: May 29, 2013Date of Patent: September 27, 2016Assignee: General Electric CompanyInventors: Satyanarayanan Seshadri, Marko Klaus Baller, Dinesh Rakwal

Patent number: 9303330Abstract: The present disclosure relates to methods for manufacturing porous mesh plates for use in ultrasonic mesh nebulizers, and the porous mesh plates manufactured by those methods. Cone-shaped dimples are first drilled in a substrate (e.g. a plate), but do not penetrate the bottom of the substrate. Next, the substrate (e.g. a plate) is subject to an electrochemical process to remove a layer of material from the surface of the substrate. Enough material is removed to allow the dimples to penetrate the substrate, thereby creating holes in the substrate. The size of the holes can be controlled by the conditions of the electrochemical process.Type: GrantFiled: June 7, 2013Date of Patent: April 5, 2016Assignee: General Electric CompanyInventors: Guruprasad Sundararajan, Marko Klaus Baller, Swarnagowri Addepalli, Satyanarayanan Seshadri, Dinesh R. Rakwal, Subhashish Dasgupta, Heikki Haveri

Patent number: 8721767Abstract: An electrostatic screen battery for emission control (ESBEC) system includes a plurality of screens. The screens are arranged in an alternating manner so that screens at a first electric potential are interposed with screens at a second electric potential. An ionizer is disposed upstream of the screens. An exhaust stream passes by the ionizer and then through the screens, where particulates are deposited onto the screens. In preferred embodiments the screens have hydrophobic surfaces.Type: GrantFiled: September 7, 2010Date of Patent: May 13, 2014Assignee: Rutgers, The State University of New JerseyInventors: Gediminas Mainelis, Taewon Han, Satyanarayanan Seshadri

Patent number: 8104362Abstract: An inline virtual impactor comprising an outer housing having a housing inlet, a housing inner surface, a major flow outlet and a minor flow outlet; a flow accelerator member disposed in the upstream portion of the outer housing; and a flow stabilizer member disposed within the outer housing downstream of the flow accelerator member, wherein the disposition of the flow accelerator creates an annular flow passage between the flow accelerator and the outer housing, and wherein a flow divider that is at least partially downstream of the flow stabilizer member effects splitting of the flow stream entering the housing into major and minor flows. The minor flow comprises primarily particles having a size greater than a cutpoint size and the major flow comprises primarily particles smaller than the cutpoint size. The inline virtual impactor may further comprise an aspiration section located upstream of the flow accelerator member.Type: GrantFiled: January 7, 2009Date of Patent: January 31, 2012Assignee: Texas A&M University SystemInventors: Andrew R. McFarland, Satyanarayanan Seshadri
