Abstract: An exercise device having a thin, hollow, rectangular body and having a planar upper surface to receive a portion of a user's body thereupon. Each of a pair of handles is attached to respective ends of a cord that passes through a first guide mechanism located at a front corner of the upper surface, through an interior portion of the body and back through a second guide assembly located at a second front corner of the upper surface. Each guide assembly consists of four mutually orthogonal rollers defining a central, rope-accepting opening in the middle thereof. One or both handles may be adjustably attached to the cord to allow use of the exercise device by different height. The exercise device may include a handle attached to the body and one or more feet disposed on a lower surface of the body.

Abstract: A collapsible, compactable chair or seating apparatus having a pair of rigid frames hingedly connected to one another to form an A-frame configuration. Both frames may be collapsed so that the frame dimensions of the chair in an operational, deployed configuration may be reduced in two dimensions (i.e., height, length) when collapsed into a compacted configuration for storage or transport. The novel chair may be compacted into a thin bundle that may be rolled up in and contained within fabric forming a portion of the chair. In its compacted, rolled up state, the novel chair is suitable for transportation within a backpack or other such enclosure.

Abstract: A target apparatus adapted to receive projectiles such as bottle caps tossed or otherwise launched towards the target. Three vertically aligned catch structures are disposed to receive and retain the bottle caps. The three catch structures have different sizes resulting in different degrees of difficulty in projecting a bottle cap into the respective structures. The lowest catch structure is the largest, the middle catch structure being the smallest, and the uppermost catch structure being sized between the lower and the middle structures. Chains completely surround the middle and upper catch structures. Chains only surround the sides and rear of the lowest catch structure. An opening in the front of the lowest catch structure is adapted to receive a projectile therein that is routed to a special basket. A scoring system is provided that awards points depending upon which of the catch structures retains a bottle cap.

Abstract: An attachment for a conventional, walk-behind power tiller for forming seed rows and adjacent furrows wherein an auger disposed perpendicularly to the seed row being formed has a larger diameter at its proximal ends and a smaller diameter at its central, inner end. The auger is rotated using power derived from the tiller to which the novel seed row forming apparatus is attached. In operation, the larger diameter outer portions of the auger dig a furrow and move the disturbed soil inwardly along the diminishing diameter of the auger, thereby depositing the soil from each side of the auger into a central berm or seed row. The apparatus provides seed row-forming capability for use with small rotary tillers and provides minimum soil tillage while readily forming planting rows.

Abstract: An adapter to facilitate attaching non-standard implements to a tractor equipped with a proprietary quick-connect hitch system. An elongated horizontal member, equipped with cylindrical end regions adapted for securing in hook regions of a quick-connect hitch system, carries a ball hitch or other similar universal hitch attachment mechanism. The novel adapter, therefore, allows attachment of implements having a ball hitch, a universal pin type hitch or other non-standard attachment mechanism to tractors equipped with quick-connect hitch systems. The novel adapter is rotatable around its major axis to allow two diverse hitches to be accommodated. For example, a ball-type hitch as well as another type connection my be selected by rotating the adapter 180° around its major axis.

Abstract: An improved bilge water level monitor, alert and control system for boats and other vessels. The system provides a method of detecting excessive leakage of water into the bilge and in response to the excessive water in the bilge, triggering an alarm to notify the operator and others and energizes bilge pumps to remove the excessive water. The system is designed with many redundancies in the sub elements and subsystems for safety. The system provides a means for reducing the likelihood of exhausting battery power in the event of a significant seawater leakage problem. The electrical power rating of the monitoring circuitry components is relatively low, thereby reducing the size and weight of those components relative to prior bilge pump monitoring and alert systems. There is no electrical wiring exposed to bilge water during system operation thereby reducing damage to the wiring components.
