Abstract: A waste water filter system has a collector body (14), a disposable filter (20) positioned within the collector body which retains particulate matter and grease while not retaining waste water, and an access aperture (28) in the collector body for removing and replacing the filter.

Abstract: Disclosed is a method for killing animal pests infesting a water-bearing product and including placing the product in a chamber having at least some oxygen therewithin and reducing the pressure in the chamber below atmospheric pressure. The improvement comprises the steps of reducing the pressure in the chamber at least to the boiling point of the water in the product so that oxygen in the chamber is displaced by water vapor until the chamber is substantially oxygen depleted. The oxygen depleted condition is maintained for the "time of lethality," i.e. for a time at least equal to the time required for a pest to be killed in an oxygen-depleted environment. Specific aspects of the new method also involve using inert gas and a poison gas fumigant.

Abstract: A collapsible shelter of the umbrella-tent type including a foldable frame and a cover of sheet material affixed to the frame. The frame comprises a plurality of support members having mutually respective ends pivotally connected to a central hub. The central hub is mounted on elongate erecting guide means located at the apex of the frame. A second hub is mounted on the guide means below the central hub, and a plurality of rib members are pivotally connected at mutually respective ends to the second hub, with the other ends of the rib members being pivotally connected to corresponding, respective support members, so that when the shelter is in its erected form, the support members extend outwardly and downwardly from the central hub, the second hub is positioned adjacent or proximate to the central hub, the rib members extend substantially radially outwardly from the erecting guide, and the cover is held tautly affixed to the frame.

Abstract: A collapsible shelter of the umbrella-tent type including a foldable frame and a cover of sheet material affixed to the frame, wherein the frame is provided with ground-engaging foot members which firmly secure the bottom and/or floor of the tent to the base of the frame. The tent frame comprises a plurality of support members which, when the shelter is erected, extend outwardly and downwardly from the hub to the ground. The novel foot members comprise a central body attached to the downwardly extending end of the respective support members. An elongate base is connected integrally with the central body portion of the foot member, and an elongate opening is provided in the base for attachment of one end of a strip of webbing or fabric which is attached at its other end to the bottom and/or floor of the tent cover. Means are also provided for attaching and anchoring a tie-rope or cord to the foot member.

Abstract: Means for slidably attaching a piece of fabric material to a tubular support member is disclosed, comprising a ring member which circumscribes the support member and is adapted for sliding movement therealong. The ring member has a key-type extension thereon which is adapted to releasably engage a corresponding locking connector which is attached to the fabric material. The attaching means are advantageously used in connecting the fabric portion of a collapsible shelter of the umbrella-tent type to the collapsible frame of the shelter.
