Publication number: 20240109089Abstract: A container closure can include a collar, an actuator, and a biasing element. The collar can be configured to couple to a container. The collar can have a container facing surface and a second surface opposite the container facing surface. The actuator can be movable relative to the collar from a first position to a second position. The actuator can be in fluid communication with a cavity defined by the container such that the actuator dispenses material out of the container as the actuator moves from the first position to the second position. The biasing element can have a first portion coupled to the actuator and a second portion coupled to the second surface of the collar, the biasing element configured to bias the actuator toward the first position.Type: ApplicationFiled: September 30, 2022Publication date: April 4, 2024Inventors: William Henry Carr, Kelly Gail Duncan, Matthew Lawrence Norris

Patent number: 11629605Abstract: A turbine wheel consists of a first shroud component and a second bladed disc component. The shroud component comprises a shroud structure, a hub structure and a spoke formed integrally therewith and extending between the shroud structure and the hub structure. The bladed disc component comprises a hub member having inner and outer rims, turbine blades disposed on the outer rim, and at least one receiving zone for receiving the spoke, said at least one receiving zone extending radially between the inner and outer rims. The shroud component and the bladed disc component are connected and thus provide the turbine wheel with a shrouded portion. A shrouded turbine wheel can therefore be conveniently assembled starting from at least two components. Further, these components have simplified geometries for easy manufacture, for example using a casting technique, while the overall mechanical performance of the turbine is preserved or improved.Type: GrantFiled: March 28, 2019Date of Patent: April 18, 2023Assignee: Cummins LTDInventors: Henry Carr, Paul Ghosh
