Abstract: A device is adapted to be used in conjunction with a racquet for tennis or for a similar sport, and wherein the racquet is strung with a plurality of strings under a certain tension. The strings extend in a mesh along longitudinal and transverse directions so as define a plurality of rectangles. Each rectangle has sides of predetermined dimensions, and is bounded by a pair of adjoining strings extending along the longitudinal direction. Another pair of adjoining strings extends along the transverse direction. At least one plate of elastic material is adapted for being emplaced in one rectangle so as to engage at least two adjoining strings, and is of such dimensions so as to, upon emplacement, deform the so engaged strings so that they are spread apart by a distance exceeding the predetermined dimension by about 2 to 3 millimeters. Thus the so engaged strings are subjected to a supplemental tension exceeding the certain tension. In a preferred embodiment a weight is attached to the plate.
Abstract: The lengths of string (22 and 24) of a racket, more specifically a tennis or squash racket, are trained over bend points of the frame (12) with a low degree of friction and are so strung backwards and forwards across the frame that the spacing between two parallel strings of the same length of string (22) is at least equal to the radius of a ball. Between these strings (22c and 22d) there are parallel strings (24d), that are parts of other string lengths (24). This system of stringing the frame makes it possible for tension forces produced on ball impact to be transmitted to other parts of the array of strings not contacting the ball.
Abstract: A device for straightening misaligned strings of a stringed racket, including an elongated rigid member forming a substitute finger. One end of the device includes a gripping member for gripping the device and a hook is supported from the other end of the elongated member and extending transversely thereto. The hook has both forwardly facing and rearwardly facing bent portions, so that it may be used alternately for pushing or pulling a selected string.
Abstract: A racket comprised of a frame connected to a handle wherein the frame has a retaining channel that extends around its outer periphery. The frame also has a plurality of holes extending therethrough for receiving individual strings. Slidable within the retaining channel are a plurality of retaining members that have recesses in their end portions. The recesses serve to define string holes when the retaining members are placed together. Each of the strings has a portion of increased extent at each end such that the strings can be passed through the frame hole while at the same time being secured to the frame by way of the string holes on the retaining members. Since the string holes in the retaining members are smaller in size than the portion of the string of increased extent, the strings are held in place in the frame.
Abstract: The invention relates to a frame for a games racket e.g. tennis, of the type made as a hollow injection moulding of reinforced thermoplastics material. The frame has attachments for stringing in the form of a series of discrete lugs moulded integrally with the walls of the hollow frame and so positioned that the racket strings in their desired positions do not pass to the outer periphery of the head. The discrete lugs may for example be around the inner periphery of the head of the frame and each contain an integrally-moulded circumferential bore for string passage. The frame may be made by injection moulding around a fusible core and the shape of the core required to give the desired lugs provides strong resistance to movement under the injecting pressures hence giving improved product uniformity.
Abstract: A racket for ball games is comprised of a handle and a head. The head and handle are pivotably connected so as to be foldable by an Omega shaped pivot pin having a pair of longitudinally offset pivot axes. Vibration dampening material is disposed between the handle and head and provision is made for locking the handle and head in playing position.
Abstract: A game board utilizes and teaches the basic playing and wagering parameters of a casino craps game while challenging player against player in strategic card play. The game board includes series of wagering areas before each player simulating betting areas on the casino craps table, a central pot area and a ladder-like token step advance area. The play of cards, equally dealt to the players from a standard deck, is dependent on the same throw(s) of dice as is the craps wagering play. Movement of a token is dependent on the possible discard after each throw of dice of one or more cards of a value or values reflecting the sum of the dice indicia on the thrown dice. Winning wagers or rewards are paid from a central pot area on the board from antes of the players and from previous lost wagers which are placed in the central pot area. The winner may either be the player or partnership able to first discard all its cards or move his token to the central area along the token ladder.
Abstract: A racket includes a head portion having a peripheral notch located therein. A string protector comprised of a connecting section having first and second resilient tongues is situated within the peripheral notch. Each of the tongues has an elongated projection extending therefrom such that the projections oppose each other. The connecting section also has tubular string guides extending therefrom for receiving a racket string. The force of the racket strings tends to push the string protector into the peripheral notch of the head portion, thereby forcing the resilient tongues toward each other so as to close over the strings.
Abstract: An autotransfusion system for collecting and salvaging blood from a patient's body cavity and for returning it to the patient includes a collection bottle which is detachably connected by an arrangement of ports and an adapter to a source of suction as well as to a conduit from the patient. When the bottle is connected to the system the suction draws the blood into the bottle. When the bottle has been filled and it is desired to return the blood to the patient or for further processing before returning it to the patient the container is easily detached and may be connected to an intravenous delivery set. During reinfusion blood may continue to be collected by the system by replacing the original container with another container. The system may be operated by suction from commonly available fittings in hospital environments or may be connected to a thoracic drainage system to utilize the suction from that system to operate the autotransfusion device.

Abstract: The present invention is of a game which includes the board, cards, playing pieces and the rules for playing the game. The basic principle of the game deals mainly with the purchasing of alphabet letters from an alphabet bank for a predetermined price displayed on the surface of the gameboard. Each player trys to obtain enough alphabet letters to spell out a word while avoiding his opponent's scheme to get his alphabet letters and eliminate his ability to spell out a complete word. Players purchase alphabet letters with play money, and in turn collect a pay-off price for each word. The player that accumulates ten thousand dollars first or eliminates all other players out of the game is the sole winner.
Abstract: A stringing system for a racket consisting of two elements, a prewoven net of individual strings and a two piece fixing device, acting as a string clamp in the string hole of a racket frame under the string's own tension. A first member of the fixing device is tubular in shape and is designed to extend through the interior of the racket frame hole. Its upper portion extends outward from the frame hole and has a slot which separates it into two half shells. A second member of the fixing device is placed over the frame hole and is located entirely exteriorly of the hole. The exterior surface of the second member is adapted to the profile of the racket frame. During stringing of the racket, the first member is placed inside the second member and into the frame hole. The string is passed through the hole in the first member, such that when the first member slides into the second member, its two half shells are pressed together around the string to hold the string in place when under tension.

Abstract: A game apparatus for playing a strategic game of economic and political development includes a game board organized in a map format wherein ficticious continental regions are located in an ocean region. The continental regions are sub-divided into territories, and the map is overlaid with a gridwork of lines defining a matrix of sectors. The territories are distinguishably indexed and some of the territory are indexed with markings designating native resources. A set of territory cards indentify the territories, and a set of resource cards, some of which have additional resource designations, are in one-to-one correspondence with the territory cards. Each player has a scoresheet which accumulates point factors; each scoresheet is organized as a chart of point factor category rows which relate to developmental characteristics, and the rows are formed in sequential columns corresponding to rounds of play.
Abstract: A portable string aligner for tennis rackets, racquetball rackets, and for other game equipment in which a racket is used. The aligner combines an elongated rectangular base member with multiple spacing pegs removably fitted in a retainer track. The spacing-peg tops protruding externally through a track opening in one surface of the base member are of sufficient length and are shaped to fit through the squares formed by the vertical and horizontal cross-over of the racket strings in a strung racket head. By hand pressuring the spacing pegs through the racket string squares, the racket strings can be restored to proper alignment on the court during pauses in play.
Abstract: Shock and vibration is suppressed in a racquet having a tubular frame of metal, graphite, fiberglass, or the like, by a bar or column of shock-and-vibration-absorbing material such as foam. The bar is 5 inches to 10 inches in length and is weaved over and under the vertical strings in the region, between the handle and the nearest cross or horizontal string, where a ball or shuttlecock would not impact in normal play. The ends of the bar are brought through the end spaces between the string and the frame of the racquet and tucked under the frame. The bar is composed of layers of the shock-and-frequency absorbing material. The material is soft, light and resilient. The inner layer or layers has a higher density than the outer layer. The frequency for which the maximum absorption occurs decreases progressively from the inner layer or layers outwardly. The resonant frequency of a typical racquet is about 650 hertz. The predominant absorption frequency of the outer layers of the bar is between 500 and 2000 hertz.

Abstract: A racquet for striking a ball or other projectile in a game, having a stringed head, in which the racquet is so constructed that, for an impact in the region of the sweet-spot, each of those strings which yield do so substantially symmetrically about a plane which is perpendicular to the string and which passes through the center of impact. The racquet includes a diagonally strung hitting surface and an open throat design defined by a bridge portion whose linear density is equal to the linear density of the rest of the frame. In addition, the racquet half located closest to the grip weighs substantially the same as the racquet half located farthest from the grip. The resulting structure of the racquet serves to centralize the sweet spot of the racquet at the geometric center of the circular head portion.
