Patent number: 11591988Abstract: A valve, such as a throttle valve plate, which is suitable for use with a throttle assembly, and is able to withstand a backpressure test. The throttle valve plate includes a flat plate, and a plastic material overmolded onto a portion of the valve plate. The plate includes at least one rib, and may include a plurality of ribs, allowing for a thinner and lighter weight plate which is manufactured at a lower cost. The valve may also be a two-piece valve plate having an overlap portion. The two pieces of the valve plate overlap at the portion of the valve plate which interfaces with the shaft of the throttle assembly. The remaining portion of the plate surface includes at least one ribbed feature, and may include a plurality of ribbed features which reduce material usage and therefore reduce weight and cost, but also provide the required strength and rigidity.Type: GrantFiled: March 11, 2021Date of Patent: February 28, 2023Assignee: VITESCO TECHNOLOGIES USA, LLCInventors: Julian Czajkowski, Donald Taylor, Mohammed Rizwan Khan

Patent number: 11449403Abstract: A method and system for detecting faults in a communication interface is disclosed. The communication interface is connected to a field device and a device bus comprising generating periodic diagnostic pulse by a programing unit. The programming unit is communicatively connected to the controller and a controller interface and provides the diagnostic pulse to a multiplexer to periodically apply the diagnostic pulses from the programming unit to a first winding of a transformer. The programming unit provides the diagnostic pulse to the isolation unit. A sensing unit senses a voltage drop across a sense resistor, the sensing unit having an input connected to the sense resistor and an output connected to the programming unit. The sensing unit communicates a sense signal based on the comparison to the programming unit, and switches from a primary or a secondary module to the other based on the sense signal.Type: GrantFiled: October 9, 2019Date of Patent: September 20, 2022Assignee: Honeywell International Inc.Inventors: Amit Kulkarni, Ganesh Ratilal Patil, Mohammed Rizwan, Vimal Kant

Patent number: 11124451Abstract: A method of making a structural lightweight and thermal insulating concrete is described. The concrete has a coarse aggregate partly replaced by recycled plastic pieces. This enables the concrete to maintain a high compressive strength, low thermal conductivity, and low weight, while providing a use for waste plastic. The waste plastic pieces may comprise polyethylene in the form of flakes, fibers, or granules. Due to its low unit weight, adequate compressive strength and high thermal resistance the developed concrete can be used as a structural lightweight and thermal insulating concrete. The use of this concrete leads to economic and environmental benefits.Type: GrantFiled: February 18, 2020Date of Patent: September 21, 2021Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Mohammed Rizwan Ali, Jobin Jose, Salah U. Al-Dulaijan, Shaik Inayath Basha, Mohammed Maslehuddin
