| 202 | Practice ball | US10216145 | 2002-08-09 | US06746351B1 | 2004-06-08 | Robert I. Goodman |
| A ball is provided for use in training that collapses when hit or kicked and then resiliently reforms itself to its original shape, dissipating kinetic energy and allowing use of the ball in a restricted geographical area. In one aspect, the ball of the invention includes incisions extending substantially through a shell, which deform upon striking, such that the ball and collapses venting air and dissipating kinetic energy. In another aspect, the ball of the present invention includes incisions extending only partially through the outer shell, contributing to the deforming properties of the ball when struck. | ||||||

| 206 | Peptides which enhance transport across tissues and methods of identifying and using the same | US09573252 | 2000-05-18 | US06521737B1 | 2003-02-18 | Daniel Joseph O'Mahony |
| A method of identifying a peptide which permits or facilitates the transport of an active agent through a human or animal tissue. A predetermined amount of phage from a random phage library or preselected phage library is plated unto or brought into contact with a first side, preferably the apical side, of a tissue sample or polarized tissue cell culture. At a predetermined time, the phage which is transported to a second side of the tissue opposite the first side, preferably the basolateral side, is harvested to select transported phage. This modified phage is amplified in a host. This cycle of events is repeated (using the transported phage produced in the most recent cycle) a predetermined number of times to obtain a selected phage library containing phage which can be transported from the first side to the second side. Lastly, the identity of at least one peptide coded by phage in the selected phage library is determined to identify a peptide which permits or facilitates the transport of an active agent through a human or animal tissue. | ||||||

| 210 | Ball-like beverage container | US722673 | 1996-09-30 | US5638982A | 1997-06-17 | Donald Spector |
| A container adapted to store a beverage and, when empty, to function as a playball. The container includes a spherical shell formed of a flexible synthetic plastic material having a tubular neck projecting therefrom on which is received a screw-on cap. The neck is retractable into the shell whereby the neck then assumes a re-entrant form and the cap is then frictionally held therein flush with the shell. In a storage mode of the container, the shell is filled with a beverage and is sealed by the flush cap. To switch to an active mode, the shell is squeezed and the resultant internal pressure produced by the beverage causes the cap to pop out and project the neck so that the cap can be unscrewed to dispense the beverage. In the play mode, the shell is empty and the air therein is sealed by the cap which is depressed to be again flush with the shell, the container now being a pneumatic play ball. | ||||||
| 211 | Takraw balls | US314807 | 1994-09-29 | US5566937A | 1996-10-22 | Boonchai Lorhpipat; Boonsakdi Lorpipatana |
| A takraw ball having a relatively soft, or elastically deformable, surface and conventional rebound characteristics. The takraw ball may be woven from composite strips, one component of which is elastically deformable material and forms the ball surface and the another component of which is a springy material. The elastically deformable material and the springy material are selected to produce a desired rebound characteristic. The strips have a wide variety of shapes and compositions. In an alternative embodiment the springy material component forms the ball surface and the elastically deformable material provides reinforcement for the strip. | ||||||

| 215 | Game ball | US253081 | 1988-10-03 | US4880233A | 1989-11-14 | Chul-Ho Song |
| A cover replicating the appearance, texture, and surface features of a regulation baseball enclosing a flexible, hollow, spherical core. The core is fabricated from a pair of substantially similar semispherical shells made of a homogeneous, waterproof composition and bonded one to another at the circumferential edges. The composition from which the core is formed includes by weight 30-40 percent styrene butadiene rubber, 16-20 percent natural rubber, 33-37 percent calcium carbonate, and 5-9 percent silica powder, as well as diphenyl guaniden, rubber cure accelerator, and traces of zinc oxide and sulfur. The outer diameter of the core is approximately 2.6-3.0 inches with a wall thicknesses in the range of approximately 0.08-0.16 inches. The core with the cover assembled thereon has a weight of approximately 2.5-3.5 ounces, less than that of a regulation baseball, and an outer diameter substantially equivalent thereto. The cover includes two pieces of synthetic leather secured at the edges with raised herringbone stitching in the pattern of a regulation baseball. Optionally, a layer of twine may be tightly wound in random fashion about the core and the outer cover may be adhered to the structure beneath it using an adhesive. Due to its flexibility and lighter weight in relation to a regulation baseball, the disclosed substitute baseball affords an enhanced margin or safety to young and inexperienced players. | ||||||
