Abstract: A portable net device for stopping the flight of projectiles such as golf balls comprises a main member and a base member respectively formed in closed loops, a main sleeve substantially covering the main member wherein the main sleeve has a top hole and a main node cross-opposing the top hole, a fabric portion radially extending from the main sleeve for flexibly stopping the flight of projectiles such as golf balls, a base sleeve substantially covering the coilable base member wherein the base sleeve has a bottom hole and a base node cross-opposing the bottom hole, and a means for supporting the main member at a substantially erected position.

Abstract: A hanging net device is designed for attachment to an outer perimeter of an existing erectable net structure. The hanging net device has an interior member forming a collapsible continuous ring that is coilable. A fabric portion is attached to the interior member. Three or more elastic connectors are connected to the interior member. Each elastic connector has an elastic portion and an attachment end. The attachment end connects to the outer perimeter of the erectable net structure.

Abstract: A collapsible net device for stopping the flight of projectiles such as golf balls includes a main member forming a first closed loop. The main member has a main outer perimeter and a plurality of detachably connected poles. The poles connect to form the first closed loop and easily detach for storage. The fabric portion connects to the main outer perimeter of the main member for stopping the flight of projectiles such as golf balls.

Abstract: A self-erecting collapsible net for stopping the flight of projectiles such as a golf ball, the collapsible net comprising: (a) a closed loop resilient coilable member having a perimeter; (b) a fabric portion attached to at least a portion of the perimeter of the coilable member to stop a projectile impelled thereon; and (c) support means comprising at least one support member extending from a portion of the perimeter of the coilable member, the support member including a stake bore protruding therein, the stake bore being sized and shaped to receive a stake capable of being placed in a stake pocket in a substantially horizontal surface. The collapsible net can be expanded and disposed on said surface with one end of the stake introduced into the stake bore in the support member, and another end of the stake introduced into a stake pocket in said surface, thereby erecting the collapsible net in a substantially uprightly position such that the plane of the fabric is substantially transverse to said surface.

Abstract: A process for expanding tobacco is provided which employs carbon dioxide gas. Tobacco temperature and OV content are adjusted prior to contacting the tobacco with carbon dioxide gas. The disclosed process is suitable for impregnating and expanding tobacco having a high bulk density. In order to achieve a high bulk density, the tobacco may be compacted or compressed to achieve an increased and more uniform bulk density prior to its impregnation with carbon dioxide. The process may be carried out with a short cycle impregnation in an apparatus according to the invention. A thermodynamic path is followed during impregnation which allows a controlled amount of the carbon dioxide gas to condense on the tobacco. This liquid carbon dioxide evaporates during depressurization helping to cool the tobacco bed uniformly. After impregnation, the tobacco may be expanded immediately or kept at or below its post-vent temperature in a dry atmosphere for subsequent expansion.
