Abstract: A statistical analysis package for a bowling center system provides displays used to analyze bowling ball trajectories. The bowling center system includes a central processing unit having a memory and connected to a ball trajectory unit. The ball trajectory unit generates information representing the trajectory of a bowling ball in a lane which is stored in the processing unit memory. The processing unit memory is operable in response to a user request for selecting trajectory information to develop statistical graphs illustrating historical tendencies at a select trajectory position for display on a monitor.

Abstract: A tool that lowers the temperature of the heart during surgery or other times when blood flow to the heart is cut off. The tool has the appearance of a spoon and includes an elongate handle part and a heart-cradling part at the end of the handle. A first passageway formed in the handle delivers a continuous flow of cold liquid to the rim of the heart-cradling part of the tool and the cold liquid flows continuously out of perforations formed about the rim of that part of the tool for as long as refrigeration is needed.

Abstract: An apparatus for practicing golf swings indoors having a net assembly suspended from a support rail attached to an overhead structure such as the rafters in a garage. The net assembly is attached to a plurality of hangers which are slidably attached to the support rail so the net assembly can be pulled to one side when not in use. The net assembly is scrolled at the bottom to form a trough which catches balls directed toward the net and to create a seal with the playing surface and to form. Golf balls directed toward the net assembly from a playing mat having a tee are restrained and caught by the net assembly.

Abstract: An apparatus for injecting liquids into a body without using hypodermic needles, the liquid being ejected from a small orifice in a probe at a velocity which will penetrate the surface of a body against which the probe is placed. The apparatus ejects a specific small volume of the liquid under a very high initial velocity and pressure followed by the ejection of the main charge of liquid at a lower velocity so that the liquid flows into the channel caused by the initial penetration without penetrating to a greater depth. The probe is connected to a hand-held portion whose other end is attached via a flexible tube containing a suitable hydraulic fluid to two remote pressure intensifiers, one of which creates the required high initial pressure for a short period of time and the other of which provides the pressure necessary to eject the main charge of liquid at a lower velocity.

Abstract: A board game apparatus includes a playing board including a series of contiguous and continuous tracks, each of the tracks defined by spaces of varying lengths, wherein tokens directed throughout the tracks may switch lanes to gain access to varyingly length spaces to advance about the tracks. Calculator and score indicators are utilized, with each token's designated starting position throughout the track. The predetermined number of tracks include a further predetermined number of tokens, wherein at least twice the tokens are utilized as the predetermined number of tracks.

Abstract: The tennis racket frame according to the present invention has a total weight of 230-300 g and total length of 52-67 cm and a periodic damping ratio of 0.5-4.0%, which is constituted of a fiber reinforced resin composed of polyamide resin reinforced by a continuous fiber and/or long fiber reinforcing material. A resin layer containing a non-woven fabric may be provided at the inside, outside or/and in the middle of the fiber reinforced resin layer. Because of this structure, the tennis racket frame of the present invention can be light in weight and compact in size with a large periodic damping property, making it possible to avoid tennis elbow.

Abstract: A broadhead (10) having deployable cutting blades (22) (24) is kept in the retracted position, wherein the blades (22) (24) have a slimmer profile, during the flight of an arrow by a tubular, external restraint (20) which fits over the body (16) of the broadhead (10). When the broadhead (10) impacts against an animal, the plunger (18), which is slidably mounted in the front of the body (16) is forced into the body (16) and causes the blades (22) (24) to be deployed out of the slots (12) (14). As the blades (24) are moved out of the slot (14), the tubular restraint (20) is cut from the body (16) by the cutting edge (26).

Abstract: A billiard cue is formed with a forward section securably mounted to a rear section. The rear and forward sections are formed of an epoxy resin body, including a central carbon graphite core.

Abstract: An improved compact golf course simulates, with great realism, the drive, approach, chipping, and putting of a golf game played on a full scale course. The compact course provides the player with at least nine distinct target greens for his approach shot, each green having different sand or water hazards. The course provides the player with a plurality of chipping greens that may be played from the drive area. A common putting green containing nine holes is used to putt-out after the drives and approach shots have all been played out on the nine target greens. The target greens are designed to automatically clear balls from their surface. All drive, approach, and chip shots are taken from a common, relatively compact area. In an alternate preferred embodiment, distinctly marked putting zones are provided on the target greens and the chipping greens and for each of the holes on the common putting green.

Abstract: A game in which a player of the game acquires a ticket containing some information stored therein for comparison to information broadcasted from a transmitter. The broadcasted information contains a value, such as a number, corresponding to a winning number. The stored information is compared to the broadcasted information and if a match results, then the ticket is deemed to be a winning ticket.

Abstract: An outdoor game for family and friends gathered in a yard having a one-story garage roof or porch roof. The slanting, shingled roof is used to locate a plurality of traps to interrupt the descent of a ball thrown to the top area of the roof. The traps may be interspersed with diversion shields also distributed on the roof and located by flat plates inserted under shingle flaps. Baffle plates at the top of the roof are provided to prevent overthrow of the ball. A retriever shaft and arm can be used to remove the balls from the traps after a cycle of play. The traps can be provided with score indicia to allow scoring of a game by one or more players.

Abstract: A section of the play field is changed during play by replacing components mounted thereon with different components. In other words, the section of the play field is replaced with a new section. Preferably this is done by rotating the section of the play field to expose different components that were previously stored below the play field surface. In a preferred embodiment the section of the play field is coupled by a slip clutch to a continuously running motor, and a solenoid operated catch mechanism stops rotation of the section of the play field when it is approximately parallel to the rest of the play field surface. To change the components included in the play field, the solenoid is energized to release the catch and thereby permit rotation of the section of the play field by approximately 180 degrees.

Abstract: An assembly for obtaining a plurality of cluster structures in either a sequential manner or collectively having a base component portion (10) having an enlarged body (12) to which is attached, by way of flexible straps (21), a plurality of assembly component portions (20) each having an enlarged body (24) and the flexible straps (21) such that, when appropriate tension is applied to the straps (21), the bodies (24) of the assembly component portions (20) are firmly abutted to the body (12) of the base component portion (10) causing rotations of the assembly component bodies (24) in relation to each other and to the base body (12) to automatically produce a plurality of cluster structures. The base component portion (10) may have the enlarged body (12) mounted on and around an enlarged hollow-core support member (11) with the member acting as a channel for the flexible straps (21).
