Abstract: A doll capable of raising itself in a natural realistic manner from a generally prone position on a supporting surface to either a sitting position or a standing position. The doll includes a pair of legs pivotally mounted on the doll's torso for movement about their respective axes in a timed sequence and a drive mechanism including a motor and a pair of cams which control the timed leg movements. In operation, the doll is placed in a prone face down position on a suitable supporting surface with its legs aligned with the torso in a generally horizontal position. Upon activation of the drive mechanism, one leg is pivoted downwardly approximately 150.degree. to a position generally alongside the torso and then remains in that position while the second leg is brought forward to a position in generally parallel alignment adjacent the opposite side of the torso. Continued energization of the drive mechanism causes the torso to pivot upwardly to a sitting position.

Abstract: An inflatable top is described having an attached manual rotation mechanism. The rotating body portion of the top includes an inflatable, plastic enclosure which expands to a desired shape when inflated with a gas. The rotation mechanism converts a linear force applied to the top, parallel to its vertical axis, into a rotation around its axis of the top and the rotation mechanism. The mechanism includes a helical member mounted for reciprocal movement into and out of a housing secured within the top. The helical member threads through a clutch element rotated by the linear motion of the helical member. The clutch element causes the top to rotate when the force applied to the helical member is in one direction and is disengaged and does not cause the top to rotate when the force applied to the helical member is in a different direction.

Abstract: Liquid flow sensing apparatus which in the illustrative embodiment is used to sense an occluded vein (cessation of blood flow). A flexible pressure pillow is connected in the blood flow line and is inserted into a housing in contact with a metallic leaf spring. The position of the leaf spring is adjusted relative to an eddy current proximity sensor so that the sensing apparatus is calibrated to a no-alarm position during proper blood flow. If blood flow ceases, the flexible pressure pillow contracts thereby moving the leaf spring away from the eddy current proximity sensor and an alarm condition is thereby detected.
