Abstract: A solar powered passive air filter system for filtering an air space polluted with particulate matter includes an elongated vertical chimney located in association with the polluted air space and in a position to be exposed to solar radiation. A duct connects the polluted air space to the base of the chimney. A filter medium is located in association with the duct for removing air pollutants from an air stream. An air stream is created in the duct by an ascending air stream in the chimney. The ascending air stream in the chimney is maintained in response to exposure of the chimney to solar radiation.

Abstract: An easy open pouch is formed from front and back thin films by a seal formed between the films. The seal defines a product storage chamber and a dispensing cavity between the films. The seal completely surrounds the product storage chamber. An opening to the exterior of the pouch is formed in the seal in the dispensing cavity. The product storage chamber and the dispensing cavity are located adjacent to one another with a common wall located between them. The common wall is formed as a part of the seal and is frangible in response to a pressure differential between the product storage chamber and the dispensing cavity. Upon creating a pressure differential between the product storage area and the dispensing cavity the seal across the common wall delaminates to join the product storage chamber to the dispensing cavity. Product can then be dispensed from the product storage chamber through the dispensing cavity and out of the dispensing cavity opening.

Abstract: A packaging cup formed from a resilient material has an integrally body having a product reservoir and a lip. The product reservoir includes a flat bottom wall and a continuous side wall integrally joined together about a smooth curve. The side wall extends upwardly from the bottom wall to join the lip. The joint between the lip and the side wall continuously surrounds and defines an opening through the lip to the interior of the reservoir. The lip extends in a plane outwardly from this opening completely around the periphery of this opening. The bottom wall is essentially circular in shape and the opening is essentially squarish in shape. First, second, third and fourth fluted areas are located in the side wall at the corners of the squarish shaped opening. Each of the fluted areas is shaped essentially as a conical surface generated from a cone which is truncated by a plane about a parabolic intersecton of the plane with the cone.

Abstract: This invention is directed to a segmented head seal for a cup packaging machine which has independent sealing head segments. The segmented head seal has a mounting plate having an insulator plate attached thereto. Attaching to the insulator plate is a support plate. Attached to the support plate are a plurality of locator assembly members. Movably linked to each individual locator assembly member is an independent sealing member. The links between the sealing members and the locator assembly members allow the sealing member to move on the locator assembly member. The locator assembly members are attached to the support plates with one or more bias springs located in openings in the locator assembly members between the support plate and the sealing blocks.

Abstract: A packaging cup of the type typically utilized to contain a small volume of a condiment and formed of a resilient material which has a reservoir and a lip which surrounds the reservoir with a lid sealed to the lip is improved by including support fingers formed in the lip. The support fingers are formed by including slits in the lip which separate segments of the lip into the support fingers. Each of these segments, however, is maintained to the lip by a connectable portion. The support fingers are bendable about the connecting portion allowing positioning of the support fingers out the plane of the lip. When positioned out of the plane of the lip the support fingers can be engaged over a surface as, for instance, the vertical wall of another container to hold the packaging cup on the vertical wall of the container.

Abstract: A free standing product pouch for containing a product as, for instance, a fluid product includes a pouch formed with an elongated edge having ends. The pouch is folded about a point on the edge to locate the ends of the edges together in proximity with one another. The ends of this edge are connected together to maintain the pouch in a folded configuration. The folded configuration of the pouch is free standing on a surface.

Abstract: For use on a form, fill and seal bagging machine a left side bag gripping member and a right side bag gripping member are located in association with a movable component of the bagging machine as, for instance, the head seal. The bag grippers contact and grip the left and right respective sides of a bag and spread these sides apart from one another just prior to formation of a cross seal on the bag by the head seal. This insures that the heat sealable film utilized on the machines is not puckered or pinched by the head seal therefore leading to a defective seal between the front and rear films forming the bag.

Abstract: A holder for supporting a pair of eyeglasses is provided wherein a support bracket is formed out of a flexible body panel with the support bracket being a substantially rigid arch defining a vertically extending opening which is sized to permit insertion of a temple piece of the eyeglass so that the pivotal connection between the temple piece and the frame rests on the arched support bracket thereby suspending the glasses by securing them to an upright surface to which the holder is attached.

Abstract: A blood filtration unit for filtering multiple units of blood comprising means for attaching the unit to a blood reservoir, a drip chamber and a segmental filtration compartment for filtering blood.
