Abstract: An automatic volume controlled sequential irrigation system and automatic volume controlled irrigation valve therefor includes an inlet port connectable to a source of pressurized water, a discharge port, a bypass port, a valve in the discharge port movable between an open position and a closed position and a valve in the bypass port movable between a closed position and an opened position. The irrigation valve also includes a mechanism for selecting a predetermined volume of water to be discharged from the discharge port which measures the volume of water discharged from the discharge. When a predetermined volume of water has passed through the discharge port, the discharge valve moves from the open position to the closed position and the bypass valve moves from the closed position to the open position.

Abstract: An apparatus for the continuous, automatic manufacture of individual shoe covers includes a supply of two continuous webs of material, a device for advancing each of the two webs through the apparatus, an adhesive applicator for applying an adhesive at longitudinally spaced increments to at least one of the webs, a pressing station where the webs are pressed together to form adhesively joined segments at the longitudinally spaced increments, a hole producing station where holes are made in the adhesively joined segments, a second pressing station where the webs are again pressed together, stations for sewing one longitudinal edge and selected portions of the other longitudinal edge together between adjacent adhesively joined segments, and a severing station where the webs are cut through the adhesively joined segments to form individual shoe covers. The hole producing station may include a rotatable member having a number of pins extending from it.

Abstract: In a method and apparatus for making disposable shoe covers from a substantially continuous supply of material, the material is moved continuously through a plurality of operating stations wherein two parallel sheets of the material are joined to form a shoe cover. The webs of material are drawn from two supply sources along a parallel path where an elastic band of material is attached to one edge of both webs and are united by glueing and stitching operations. In addition, when desired, a static strip is added as the web moves through the apparatus. After the webs of material have been joined, the apparatus cuts the length of joined webs into discrete lengths to define the individual shoe covers.

Abstract: An apparatus for encapsulating an article within a plastic foam material, such as polyurethane, wherein the article to be packaged is placed within a mold cavity of an adjustable mold, the walls of the mold are adjusted according to the size of the article and a liquid polymericisocyanate mix is injected into the mold cavity and allowed to react to form an insoluble, flexible, polyurethane foam which completely encapsulates the article. After the urethane has set, the mold walls are retracted and the encapsulated article is removed. The apparatus consists of a mold form having a base plate and four upstanding movable side walls which define a mold cavity. Each upstanding wall is movable with respect to the other walls thereby to allow for a wide variation in the size of the mold cavity to accommodate wide variations in article size.
