摘要： A coupling device for joining together two fluid conduits and for providing fluid access to fluid in the fluid conduits. The device comprises a first coupling member which is adapted to be connected to one of the fluid conduits and a second coupling member adapted to be connected to the other fluid conduit. The first and second coupling members are adapted to be connected together to define an axial fluid passage therethrough between the two fluid conduits. An elastic member having an axial fluid opening therethrough is interposed between the first and second coupling members and the axial fluid opening thereof is axially aligned with the axial fluid passage defined by the first and second coupling members. Connecting means are also provided for connecting the first and second coupling members together to compress the elastic member between the first and second coupling members to seal the axial fluid passage. Also, at least one of the first and second coupling members includes an opening therethrough adjacent to the wall of the elastic member whereby selective fluid communication with the fluid in the fluid conduits can be obtained through the wall of the elastic member.

摘要： Control apparatus for controlling or adjusting the position of a control member is disclosed. The control apparatus includes first and second members, pivotally connected together to pivot about a point. A control member is mounted on the first member and is disposed at a first distance from the pivot point. Coarse control means operatively associated with the control member are provided for coarsely adjusting the position of the control member relative to the second member. Further, fine control means are provided for finely adjusting the position of the control member relative to the second member. The fine control means acts at an action point on one of the first and second members to pivot the first and second members relative to each other about the pivot point. The action point at which the fine control means acts is a second distance from the pivot point which is greater than the first distance such that a selected amount of movement of the action point results in a change in position of the control member relative to the second member, the amount of change in position being less than the selected amount of movement.
