  • Publication number: 20080093015
    Abstract: A method of making an elastic composite is provided. The method entails conveying a first web of material along a web plane path. The method also entails applying a first section of a first elastic strand onto the first web and generally transversely to the web plane path and applying a second section of a second elastic strand onto the first web and generally transversely to the web plane path. These applying steps are repeated while performing the conveying step, thereby arranging a plurality of first and second elastic elements on the first web, in generally parallel relation to one another. The resultant composite is suitable for incorporation into a disposable absorbent garment, textile or fabric structure, and the like.

  • Patent number: 4780065
    Abstract: The present invention relates to an improved cylinder pump. The cylinder pump includes air hoists enabling the entire pump assembly to be lifted so that a container may be placed thereunder and thereafter the air hoists may be biased downwardly so that the follower plate of the pump mechanism will bear down on top of the liquid contained within the container. Thereafter, the air cylinder of the pump is activated and reciprocated up and down through the provision of a four port reversing valve activated through the use of air sensors to cause the pump to pump fluid out of the container while the downward bias of the air hoists keeps the follower plate in contact with the surface of the liquid within the container. By separating the air cylinder actuator for the pump mechanism from the four port reversing valve thereof, improved reliability and quietness are attained.
