Abstract: The disclosed field game employs a soft, non-resilient ball not retaining a definite shape which is caught, manipulated and flung back and forth over a self-supporting scoring obstacle by players each using a racquet consisting of a flexible staff with a containing network at each end to catch, manipulate and fliong the ball.

Abstract: The preferred latch device consists of two elements, attached to interfitting longitudinally movable slide members in a relationship to pass adjacent to one another as the slide members move longitudinally. The elements each carry stops which are positioned to engage one another as the elements come into an adjacent relationship to limit further travel of the slide members. One of the elements is pivotally attached to its slide member, and movable both clockwise and counter clockwise, to displace the stops sufficiently to clear its stops on the other element and permit the slide members to be disconnected. Preferably the rear faces of the stops on one element are sloped in parallel planes to engage the stops on the other element as the slide members are being reconnected, and to cam the pivotal element sufficiently to cause the stops to clear one connection, permitting the slide members to be easily reconnected.

Abstract: A water treatment device is described which incorporates an easily changed cartridge containing an open-cell foam having a water treatment material contained therein, such as granules of a halogen compound. The device includes an adjustable orifice valve member which may be selectively positioned to control the water flowing through the cartridge. Thus, the device may be included in a water treatment system to treat either water flowing a source to a storage tank, or water being recirculated back into the storage tank.

Abstract: A pocket door suspension system which permits the door to be moved, without skewing or sagging, from a closed position to an open and retracted position adjacent a supporting wall, the system having two telescoping slide assemblies mounted to the supporting wall, the door being attached by hinges to moveable members of the slide assemblies. Two cables are provided, each attached at one end to the back end of one fixed slide member and at the other end to the front end of the other fixed slide member. Each cable is slideably attached to the moveable members of the slide assemblies such that the pair of cables trace an "I" figure, the pair of cables effectively preventing the moveable members of the slide assemblies from moving out of a predetermined relationship to each other.

Abstract: Embodiments of a neew hummingbird feeder are disclosed, each effectively preventing birds and bees from feeding, yet allowing hummingbirds to feed, by providing upwardly projecting feeding channels with outer openings that are at least 3/4 of an inch (and preferably 13/8 inches) beyond the normal level of feeding solution in the dispensing cap.

Abstract: A triangular fence post is disclosed which includes a longitudinal slot in one side formed by two inturned flanges, the spacing of the slot being less than the width of a fastener, the inner ends of the inturned flanges being turned towards one another to bite into a fastener driven into the slot. Because of this construction, the clamping action of the flanges and the bite of their inner ends cooperate to securely hold the fastener to the fence post, irrespective of the extent of penetration by the fastener into the slot beyond the flange ends. This arrangement enables any of various types of fasteners to securely hold any gauge of wire or wires in any desired state of tension, or even to hold boards if desired.

Abstract: The disclosed semi-buoyant lift-augmented aircraft, preferably of immense size, includes a fuselage of airfoil shape formed by a rigid geodesic type web framework enclosing buoyant cells pressurized to reinforce the framework. Wings are provided which impart aerodynamic lift to the aircraft, with the airfoil fuselage. The buoyancy is provided to counteract a major proportion of the great weight of the structure and to thus improve the aircraft's payload capability and range. These features maintain it airborne at reasonable speeds over a substantial altitude range.

Abstract: The described hand loom is formed of a resilient sheet and includes resilient, durable peripheral bars projecting beyond the sheet, the bars being of a size and location to permit threads to be wrapped about them. Preferably, the loom is injection molded as a plastic grid, includes peripheral bars that may hold both warp and weft threads, or loops of a knitted fabric, the bars and sheet being co-planar. The loom may be formed in any of a variety of shapes, and may include an interior opening with bars projecting into it permitting the weaving or knitting process to extend over the outer edge of the sheet or from one side to the other side. A new method of weaving also is described.

Abstract: The golf club weighted attachment is formed of a flexible sheet shaped to be wrapped about a golf club, the sheet including a weighted mass and means such as mating Velcro surfaces or snaps to removeably attach the sheet and the weighted mass it carries about a golf club. The weighted mass preferably is carried in narrow, elongated pockets formed in the sheet, the pockets being spaced to be in an opposed relationship when the attachment is affixed about a golf club. In one embodiment, the weighted mass is provided by relatively flat, pliant members, while in another embodiment granular material is carried in pockets that may be opened.

Abstract: The disclosed line releasing clamp receives a line in a saddle portion of the clamp, the line including a stop lug that is caught against the end of the saddle to resist the tension of the line. The saddle in turn is received in, and pivotally attached to, a clip. Upon the tension in the line exceeding a predetermined amount, the saddle slips free of the clip and pivots sufficiently to permit the stop lug to slip from the saddle, releasing the line.

Abstract: A carrier is disclosed for interconnecting and holding an array of cans or the like together as a unitary package. Preferably the carrier is made from a thermally shrinkable plastic sheet, and is formed to be placed around an array of cans then shrunk by application of heat to interconnect the cans and form the package. A machine is disclosed for performing this packaging operation efficiently and rapidly, the method including the step of preforming the plastic sheets to provide a cylindrical collar about each opening, thereby enhancing the hold and interconnection afforded by the carrier. A cover sheet may be employed with the carrier to keep the can tops clean. The method for performing this packaging operation also is disclosed.
