Abstract:
Golf club heads are releasably engaged with shafts so they may be readily interchanged and/or so that the shaft orientation with respect to the club head can be readily changed. Assemblies for connecting the club head and shaft may include a shaft adapter (202) and a head adapter (302). The shaft adapter may have an exterior surface extending along a first axis and a bore having a cross-sectional shape along a second axis configured to attach to a shaft member. The second end of the shaft adapter has a cross-sectional shape of a regular polygon. The head adapter has a first end and a second end along a first axis and a bore having a shape of a regular polygon along a second axis that is shaped to receive the second end of the shaft adapter in a plurality of orientations.
Abstract:
The invention is directed to devices and methods for electroliydrodynaniic (EHD) aerosolization of liquids utilizing a dissociated discharge electrode (17) and an electric field shield (7) disposed between the nozzle (5) and the discharge electrode. Preferred embodiments are designed as inhalers suitable for administration of therapeutic compounds to the respiratory tract of a patient, preferably the lungs.
