Abstract: An applicator and stimulator device comprises a flexible sleeve closed at one end and having a one or more indented cells in its outer wall and adapted to accomodate a human finger within the sleeve. In order to assist application of fluids it may have one or more cells associated with the outer wall which contain fluid which is retained by a seal. The seal is openable or rupturable when pressure is applied across the wall or the wall is in contact with an environment that weakens the seal. The sleeve is formed from an elastic material such as natural or a synthetic rubber such as a highly plasticised PVC resin. The cells associated with the outer wall are formed by creating depressions in the wall during moulding of the device. In its unflexed state the body of the sleeve is substantially cylindrical and the cells are preferably formed on a portion of the sleeve surface near to the closed end sustaining and angle of about 90 degrees over the surface measured from the axis of the cylinder.

Abstract: Fan drive mechanism includes a fan plate rotatably mounted on a spindle by bearings having an outer race secured to the fan plate, an inner race mounted on the spindle, and ball bearings rotatably supporting the outer race on the inner race. A stop nut threaded on the spindle has a forward face engaging the inner race and a radially outwardly tapering conical surface tapering from the forward face. The conical surface catches the fan plate upon failure of the bearings and separation of the outer race from the inner race and controls the wobble of the fan plate while stopping its rotation, thereby preventing the fan plate from separating from the spindle.
