Abstract: An elongate flexible band may be formed into a self-adjusting closed loop for insertion into an opening in a garment. The loop expands against the sides of the garment opening, holding the garment open to enhance airflow into the garment. A loop connector limits the closed loop to a maximum preferred diameter. The flexible band includes an accessory connector for attaching accessories such as a scent container, holder, or electric fan. The accessory connector may include retaining posts or may alternatively include flanged retaining blocks. A scent container or other accessory may optionally include flanges, flanged retaining blocks, or other attachment means. An optional timer controls discharge from a spray container into a garment. An embodiment of the invention may optionally be provided together with garment such as a glove for a hand.

Abstract: A controllable pitch propeller for application principally to sailboats employing electric auxiliary power. The design addresses a highly efficient approach to performing four basic functions desirable on sailing vessels that have electrical, or internal combustion, auxiliary power and onboard electrical systems typically employing batteries. The design employs no external nor remote actuator means; instead, blade position (nominal pitch) is inherently "controlled" by the direction of shaft rotation and whether the propeller is acting as a propulsor or a turbine. The four basic functions, or configurations, performed by the design are 1) forward propulsion, 2) reverse propulsion, 3) efficient power generation as a turbine, and 4) feathering for no-power minimum drag. The propeller includes a cambered blade configured with a cross section that would purposely act efficiently with fluid inflow impinging on either edge, depending upon the function being performed.
