Abstract: A table may include a table top, a frame and one or more support members such as legs. Advantageously, the table top may include a generally planar upper surface and a generally planar lower surface. In particular, the lower surface of the table top may be substantially free of any downwardly extending projections such as a lip. Desirably, the table includes a frame and at least a portion of the frame is exposed and visible when the table is being used. In addition, the table may include one or more guard members that are sized and configured to protect portions of the table, such as the corners. Significantly, the guard members may be selectively connected to the table top or the frame, which may allow the guard members to be repaired or replaced.

Abstract: A poolside goal system may allow various games or sports, such as basketball or volleyball, to be played in a swimming pool. For example, the poolside goal system may include a base, a goal support, a basketball goal assembly and volleyball net assembly. The basketball goal assembly is preferably movable between a first position in which basketball can be played and a second position which allows volleyball to be played. Advantageously, the basketball goal assembly may be configured to counterbalance forces applied to the volleyball net assembly. The poolside goal system may also include a wheel assembly to allow the system to be readily moved, or the goal system may be permanently secured in a fixed position. The poolside goal system, however, does not have to be used in connection with a swimming pool and it could be used in other environments or situations.

Abstract: A table is disclosed having a table top and legs to support the table top. The table top can be constructed from blow-molded plastic having an upper surface and a spaced apart lower surface. The upper surface can have features formed therein including, but not limited to, a central portion and a boundary portion. The boundary portion can include various retaining regions for holding game pieces, beverages, and the like. The lower surface can include a plurality of depressions formed therein.

Abstract: A basketball goal system may include a rim assembly that forms part of a breakaway rim that can deflect downwardly when a force larger than a predetermined amount is applied to the rim. The basketball goal system may include a support pole, a support structure including a pair of upper arms and a pair of lower arms, a backboard support frame including a pair of elongated members, and a backboard. The elongated members of the backboard support frame are preferably connected to one of the upper support arms and one of the lower support arms of the support structure, and these upper and lower support arms are preferably connected to the support pole. The basketball goal system may also include a backboard connected to the backboard support frame and a rim assembly including a pair of support arms. The support arms of the rim assembly are preferably connected to the elongated members of the backboard support frame.

Abstract: A toe shoe capable of providing support to a ballet dancer's foot while dancing en pointe. The toe shoe preferably includes a toe box in the toe of the toe shoe, an upper, and an outer sole. Support structure within the toe shoe includes a longitudinal support member, a foot encirculating tubular sleeve, and/or a toe ridge. In a first preferred embodiment, the support structure includes the longitudinal support member, foot encirculating tubular sleeve, and toe ridge. In a second preferred embodiment, the support structure includes the longitudinal support member and foot encirculating tubular sleeve. In a third preferred embodiment, the support structure is the longitudinal support member and toe ridge.

Abstract: This invention relates to a device for training an athlete to throw a ball. The device includes an elbow guide, ball guide, pole, and base structure. The pole is coupled with the base structure. The elbow guide and ball guide are attached to the pole.

Abstract: A high-temperature superconductive microwave delay line that operates in an essentially pure TEM field configuration in a compact assembly. The delay line is a planar signal delay line which includes first and second substrates made of first and second dielectric materials; each substrate can be LAO material. First and second patterned delay line segments having a configuration, are formed of first and second conductive materials on the obverse sides of the first and second substrates, respectively. On the reverse side of each of the first and second substrates, respective first and second ground planes are formed using respective first and second conductive materials, which are preferred to be high-temperature superconductive films, such as YBCO films. The delay line also includes coupling means for coupling the first patterned delay line segment to the second patterned delay line segment, thus bringing the two patterned delay line segments into substantial contact.

Abstract: A collapsible lens designed to be used as an educational device is constructed from a pouch of polyethylene plastic that is shaped to form a convex lens when filled with water. The pouch has an edge region positioned adjacent and coextensive with a portion of the radial periphery of the pouch. The edge region has an inlet and outlet opening for use in filling and emptying the lens. The openings are closed by a channel-lock seam.

Abstract: This invention is directed to continuous, non-maligant, neuronal cell lines, the cells of which: a) in the undifferentiated form are essentially free of branched process; b) stain positively for neurofilament protein and neurotransmitters; c) do not stain positively for glial fibrillary acidic protein; and d) in the presence of nerve growth factor differentiate into cells with long branched processes. Derivative cell lines of such cell lines are also contemplated. The cell lines are useful in screening methods for evaluation of chemical and biological compounds as well as for therapeutic uses.
