Patent number: 11828387Abstract: A manually operable valve for restricting airflow to and/or from a patient. The valve includes a body having one or more walls that extend between a first end and a second end. The one or more walls form a passage between the first end and the second end of the body. Two moveable members are positioned on opposing sides of the passage and axially fixed between the first end and the second end of the body. The two moveable members are configured such that depressing the two moveable members inwardly deforms the one or more walls to thereby restrict the passage. When the two moveable members are subsequently released, the one or more walls return to unrestrict the passage.Type: GrantFiled: December 30, 2021Date of Patent: November 28, 2023Assignee: GE Precision Healthcare LLCInventor: Timo Holopainen

Patent number: 11817743Abstract: An electric machine including a stator and a frame, the stator is supported with support necks on the frame in at least two axially spaced support locations. The support locations include a first group of support necks and a second group of support necks. The support necks in the first group are positioned in connection with a vertical centre plane. The second group includes two side support necks positioned opposite to each other at an angular distance above or below a horizontal centre plane. The angular distance is defined by a first angle which is determined in degrees by the formula ?1=(90/P)±(?)*(90/P), where P is the number of poles of the electric machine and P>2.Type: GrantFiled: April 27, 2021Date of Patent: November 14, 2023Assignee: ABB SCHWEIZ AGInventors: Timo Holopainen, Juha Pekka Jokinen, Carlos Chavez
