| 48 | Method and apparatus for temporarily marking a point of contact | US10500779 | 2003-01-22 | US20050043126A1 | 2005-02-24 | Jerry Iggulden |
| The present invention provides a game ball with a transient marking feature that may be used on any court surface. No preparation of the court surface is required. The game ball is coated with a temporary marking agent that is encapsulated or otherwise sealed aginst exposure to the air. When the ball contacts a surface with sufficient velocity, a small quantity of the marking agent is liberated to provide a visible mark on the surface at the point of contact. Similar to a “disappearing ink”, the marking agent dissipates after being released from the microcapsules. | ||||||

| According to a first aspect of the present invention there is provided a tennis ball having a hollow resilient core to which a needlefelt covering is adhered. The needlefelt comprises an entanglement of fibers produced by needling a fiber batt in a range of angles including a plurality of angles which are non-perpendicular to the plane of the batt, and cutting or otherwise shaping the needlefelt to form a blank adapted at least partially to cover a ball. The needlefelt includes a scrim material therein. | ||||||

| A ball-covering needlefelt produced by needling a fibre batt in a range of angles including a plurality of angles which are non-perpendicular to the plane of the batt. The range of angles is preferably achieved by the batt being curved during needling, the batt conveniently being curved in its direction of travel through the needling machine. The needleboard of the needling machine is preferably correspondingly curved. The needling process produces a needlefelt having a high degree of fibre entanglement (comparable to woven ball-covering felts) and enables achievement of characteristics necessary for good wear and abrasion resistance without the excessive consolidation in conventional ball-covering needlefelts that leads to loss of flexibility (tending to faulty ball covering) and poor dynamic characteristics (making such balls unsuitable for professional use). The invention is particularly applicable to the manufacture of championship-quality tennis balls. | ||||||

| An encapsulated marking agent is used to provide a temporary mark at a point of contact between two objects. In a specific example, a game ball is coated with a temporary marking agent that is encapsulated or otherwise sealed against exposure to the air. When the ball contacts a surface with sufficient velocity, a small quantity of the marking agent is liberated to provide a visible mark on the surface at the point of contact. Similar to a “disappearing ink”, the marking agent dissipates upon exposure to air. | ||||||

| An indoor golf game including a hole layout area enclosed by netting and a substantially planar rigid or solid rebound surface. A ball is hit from a tee in the hole layout area towards the rebound surface so as to rebound towards a hole in the green area of the hole layout. The ball used in the game comprises a ball having a hard surface so as to provide a feel of a standard golf ball, but a resilience substantially less than a standard golf ball so that the ball resiliently deforms and loses substantial kinetic energy upon striking the rebound surface. The ball has a hardness in the range of 70-105 Durometer, and a resilience in the range of 10%-40%. | ||||||

| Disclosed is a tennis ball including a continuous or discontinuous groove formed in the rubber spherical core. The groove extends about the spherical core below a track formed between two felt cover members. The groove of the spherical core controllably regularizes the air turbulence of the ball during its trajectory, and minimizes changes in air turbulence by wear or fuzzing up of the nap of the felt cover members attached to the ball. Also disclosed is an alternate embodiment for controllably regularizing the air turbulence around a tennis ball during its trajectory, using woven monofilament or multifilament synthetic fiber cover members. The diameter of the fibers and the spacing between the warp and weft fibers controls the size of exposed surface areas of the spherical core and the depth of air pockets formed between the intersecting fibers. The air pockets create a dimpled effect to control the loft or dip of the tennis ball during its trajectory. The synthetic fibers also increase the useful life of the ball, having increased strength over customary natural fibers. | ||||||
