In use, the resiliently deformable member applies a force between the container and the dispensing gun to modulate the flow of the material from the container.

Abstract: In one embodiment a device for tightening and loosening a securing device is provided. The device includes a housing, a shaft, and a clutch assembly. In one embodiment, the clutch assembly includes a clutch activation member, a first friction member coupled to the clutch activation member, and a second friction member coupled to the shaft. When the clutch activation member is in a first position, the clutch activation member engages the first friction member with the second friction member for transmission of torque from the first friction member to the second friction member. When the clutch activation member is in the second position, the clutch activation member disengages the first friction member from the second friction member to prevent transmission of the torque from the first friction member to the second friction member.

Abstract: A system includes an electronic connector configured to be coupled to a connector module and an electromagnetic interference (EMI) absorber proximate to and at least partially surrounding the electronic connector. The EMI absorber may be positioned as close as possible to the electronic connector and may be attached to the electronic connector. This positioning of the EMI absorber at least partially absorbs EMI present at the electronic connector and thereby reduces the noise on electronic signals being communicated on conductors of the electronic connector as well as reducing overall radiated emissions from an electronic system including the electronic connector.
