Abstract: An anastomotic device for temporary installation in a damaged blood vessel, having a generally tube-like shape, and whose purpose is to maintain blood flow within the blood vessel while substantially halting bleeding. The device is so inserted into the damaged blood vessel that it reconnects and reforms the blood vessel through the damaged area. The device contains an enclosed chamber, inflatable from an external source, concentric about an inner cylinder with open ends. The inner cylinder maintains blood flow while the inflated air chamber causes the device to fit snugly enough within the blood vessel to halt external bleeding.

Abstract: A goal structure for a game such as ice hockey provides a safety net which is constructed in the conventional form to provide a rigid pair of posts and cross-bar together with net supports extending rearwardly of the posts. The goal structure can be attached to the playing surface or ice by an assembly mounted wholly within the posts comprising a spring and cable, the cable passing axially of the post through an apertured guide block at the end of the post into an anchor bolt within the ice. An upper end of the spring is movable axially to apply and release the spring tension either by a transverse pin which extends into slots in the wall of the post or by an axial pin which can be held in a tensioned position by a latch. The anchor bolt in the ice allows the post to slide sideways across the ice. A plug can be placed in the ice surface when the post is removed to prevent water entering the fixture when flooding.

Abstract: Thumb twiddling devices that include a flat, hand-held housing (23) having a centrally located wheel (21) with an oblong thumb slot (35) and finger slots (33a, 33b) peripherally located about the wheel are disclosed. Thumb twiddling causes the rotation of the wheel (21) when a user's fingers (63) are interleaved together in the finger slots (33a, 33b) such that the thumbs lie in the thumb slot (35). In a toy form of the invention, thumb twiddle wheel rotations are sensed and the result used to control a display (49). In a controller form of the invention, sensed thumb twiddle wheel rotations are used to provide control signals suitable for controlling the movement of a video game object. Direction (e.g., steering) signals are provided by a tilt sensor mounted in the flat housing. Several thumb twiddle controllers can be used simultaneously by several video game "players" to control their respective objects in an interactive game.

Abstract: A cross bow trigger device having an automatically activated safety includes a trigger, a catch and at least one intermediate safety member cooperating with the catch. The catch is pivotally mounted in the trigger device and has an upper part extending above the trigger device. When a projectile pusher, such as a cross bow string, is being cocked back, it engages and pivots the catch. This pivoting motion automatically engages the catch with the intermediate safety member moving it to a position locking the trigger and preventing the trigger from being unintentionally pulled. The trigger device is also provided with a knob accessible for a user and connected to the intermediate safety member to manually unlock or lock the trigger.

Abstract: A device for training football players is disclosed. The device trains the user in the art of blocking. The apparatus includes a frame which defines an upwardly-sloping track, and a carriage which moves along the track. The carriage is connected, by a pulley system, to a hydraulic or pneumatic cylinder, or equivalent device, for imparting resistance to the movement of the carriage along the track. Forcing the carriage upwardly along the track also pushes a piston into the cylinder, retarding the movement of the carriage. A second pulley is also provided for retracting the piston from the cylinder when the carriage is moved back to its original position. The device trains the player to shift his weight while blocking, so as to tend to lift the opposing player from the ground. The amount of resistance to the movement of the carriage can be varied to simulate opposing players of varying weights.

Abstract: A visual system illustrates how many identical numerical sums turn up when two numbered dice are rolled out and how the identical numerical sums are visually differentiated, one from the other, by coding each of six numbered faces of a first die and by not coding any of the six numbered faces of a companion neutral second die. Thirty-six possible numerical sums are established when each of the six numbered and coded faces of the first die is oriented on a horizontal axis of a grid and when each of the six numbered faces of the companion neutral second die is oriented on the vertical axis of the grid. Within the thirty-six numerical sums, exists nine separate collective groups of sums, ranging in group values from three to eleven, wherein the identical sums within each collective group are visually differentiated, one from the other. The system affords a practical basis to create a variety of new dice related games, incorporating game boards, playing cards or a combination thereof.

Reduction couplings are used to facilitate the telescoping interaction and expandability and retractability of the device. Aperture and pin configurations are used to fix the vertically telescoping members into a specific location during use. Preferably the device may be formed of polyvinylchloride tubing members.

Abstract: An electrically operated line monitor for tennis which uses one or more rays substantially smaller in effective cross-section than a tennis ball to monitor areas of a tennis court adjacent critical lines thereof. The rays pass over the playing surface of the court at a height lower than the height of a tennis ball. In various embodiments, a first ray which actuates a `good` signal on essentially complete interruption of its effective part travels over an area of the court in which a ball would strike if it were "good". The first ray travels essentially parallel to and in practice slightly distanced from a perpendicular from said critical line and is so positioned that a ball in play falling across the said `good` area towards the said critical line and which just completely interrupts the reception of the effective part of the said first ray must afterwards strike the said critical line. The said first ray is the nearest `good` ray to the perpendicular from the said critical line.

Abstract: A telescopic cue for billiards, pool, snooker and the like includes telescopically engaged central and butt sections permitting infinite adjustment of cue length between two end positions and a lock for securing the central and butt sections by frictional engagement at any selected cue length. The frictional engagement is provided by a member on one of the butt and central sections arranged for radial expansion or contraction to engage frictionally the other of the butt and central sections to prevent relative axial movement of the butt and central sections. The member may comprise a collet disposed between two relatively movable abutments which are urged towards one another on relative rotation of the butt and central sections or two parts of the same section to expand or contract the member to provide the aforesaid frictional engagement.

Abstract: A game of chance in which the object of each player is to gain the least amount of weight. Each player is given a menu containing six pages of daily activities, each activity having twenty-four numbered choices. These choices have a listing of foods and/or activities which assign plus or minus calories. Serial chance selections are made by the players which designate one of the numbered choices, thereby containing a calorie value for each activity. As each player gains a predetermined weight value, he is eliminated, and the winner of the game is the longest remaining player. The status of an individual player with an overweight score is indicated by additional displays.

One embodiment has an elastic stretch cord with a first end and a second end fixedly attached to each other, so that a loop with a first effective end and a second effective end, as previously described, is formed.

Abstract: There is provided a new and useful game apparatus for combining chance play with mathematical operation. The apparatus comprises a game board having a playing surface laid out with a sequence of numbered playing spaces, a set of markers for use in marking positions within the sequence of playing spaces, and at least two dice each marked on the sides thereof with a series of numbers. The numbers in the group of series on the dice form a number set. Each series in the number set is chosen such that the first number in the first series is zero or one. If the first number in the first series is zero, then one number in each other series may be zero and otherwise no two numbers are the same within the set and each number in each series subsequent to the first series is larger than any number in any preceding series.

Abstract: Disclosed is an improved grip for tennis rackets. The grip is inversely tapered such that it narrows moving along the axis of the handle away from the head of the racket. Further, the grip is hexagonal in cross-section. In other words, the grip is substantially a truncated hexagonal pyramid. This design is structurally compatible with the skeletal and muscular structure of the human hand, wrist and arm. The inverse taper allows for more comfortable gripping by allowing the wrist to automatically go into dorsi flexion which results in permitting the fingers to flex more easily. The mobile ring and little finger metacarpals are allowed to oppose the thenar emminence thus bringing the ring and little fingers into more advantageous contact with the grip thereby making the holding of the grip less fatiguing.

Abstract: A fluid drainage system includes a suction chamber and a collection chamber. The suction chamber includes a suction regulator comprised of first and second chambers separated by a divider. An opening in the divider has a biased closing member associated therewith for opening or closing the opening according to the pressure differential between the chambers. A dash pot is connected to the closing member for damping the force on the closing member. The drainage system further includes devices for measuring the patient airflow, patient negativity and imposed suction. Those devices consist of diaphragms having dials connected thereto such that movement of the diaphragm results in movement of the dial and thereby indicating a change in one of the above noted variables. As an alternative, the drainage system includes a venturi meter for measuring airflow. Finally, the system contains an anti-spill device that prevents the spilling of fluids from the collection chamber to other chambers in the device.

Abstract: A slot machine which selects combinations of symbols on prize-winning lines by causing a plurality of lengthwise movable symbol rows arranged side by side, each of which comprises a plurality of kinds of symbols arranged at regular distances thereon, to move lengthwise, and then stopping each symbol row at one of the possible stop positions, in each of which it displays at least one complete symbol to a player through a window to position the symbols shown in the windows shifted lengthwise a half of the distance between the transversely adjacent symbols. When all the reels stop, a win decision is made base on the combinations of complete symbols stopping on the winning line or lines. The winning lines are therefore necessarily all diagonal.

Abstract: This invention is a highly damage-resistant arrow rest assembly used to hold the arrow of an archery bow in the correct position during the drawing, aiming, and launching sequences. Its construction includes a support arm which supports the arrow and a journal arm having a flat cam surface which articulates with a bow-mounting connecting plate in such a way as to allow both forward and rearward rotation of the support arm. This unlimited rotational ability of the support arm allows minimum deflection of arrow flight due to interference of the support arm with the arrow fletching and prevents breakage of the arrow rest assembly due to accidental rearward rotation of the support arm. Both the proper outward positioning of the support arm and the unlimited rotational ability of the support arm are due to a resilient bias applied to the flat cam surface of the journal arm of the arrow rest assembly.
