    摘要: A doll head defines a pair of eye apertures and a pair of outwardly extending ears. A mask also having eye apertures and ear portions is removably attached to the doll head to overlie the facial portions thereof. The mask includes a snap fit attachment which engages the ear portions of the doll head. The apertures of the mask generally align with the eye apertures of the doll head when the mask is attached. An eye change mechanism supportive within the doll head provides alternative eye images viewed through the respective eye apertures of the head and mask.

    摘要: An improved drip irrigation emitter is provided for low volume supply of water at a trickle or drip flow rate. The emitter comprises a housing adapted for connection to a water supply hose, and includes a water inlet and a water outlet with an elongated pressure reducing flow channel extending therebetween. The flow channel is lined on opposite sides by a plurality of flow diverting ribs which project laterally and partially into the flow channel in a staggered or alternating pattern, in combination with a plurality of flow diverting weirs which project upwardly and partially into the flow channel from a floor thereof. The flow diverting ribs and weirs define a three dimensional tortuous flow path for repeated back-and-forth and up-and-down directional flow change as water travels therethrough, resulting in an improved pressure drop between the water inlet and outlet.
