Abstract: A wood-type golf club head containing a fiber reinforced plastic outer shell formed by heat pressing in a mould, around an intermediate shell. A solid center core is formed inside the intermediate shell by injection of foam synthetic resin for reduced generation of harsh and keen noises at hitting balls, ideal transmission of striking energy to balls and high durability against shocks by hitting balls. The elastic modulus of the outer shell material is greater than that of the intermediate shell material. The buckling strength of the intermediate shell material is greater than that of the foam resin core material.

Abstract: A modulated VLF signal source has the capability for providing radio sign suitable for performance testing and operator training relative to VLF digital data receiving systems. A number of separately proven components are utilized to implement a relatively low cost, reliable compact and easily transportable system. A digital modulator is driven through suitably adapted microprocessor circuits by selective information stored on floppy diskettes. Operator input commands actuate the modulator to generate representations of data in the continuous shift keying, frequency shift keying, or minimum shift keying output modes to provide a modulated VLF output which can be received by several receive systems. Prolonged data transmissions can be produced by merely selecting the appropriate floppy diskettes to initiate the desired modulated sequences.

Abstract: A training interface device is connected to the output end of a store rack cable and to a modified store dispenser cable. Relays within the training interface device provide for proper indicator illumination in the cockpit of a military aircraft practicing nuclear store bombing. The training interface device further allows the use of standard practice bombs rather than expensive nuclear drop shapes.

Abstract: The disclosure describes an image pick-up assembly for use in a vehicle training simulators and the assembly has an optical system to detect images in a direction of travel and to transmit these images to an electronic camera. A terrain-following head unit is formed to traverse a terrain model and contains the optical system. A gimbal joint couples the terrain-following head unit with the electronic camera to permit relative universal movement between the two. Releasable locking device is described to lock the terrain-following head unit in an operating position relative to the electronic camera so that it is releasable by a force when the terrain-following head unit engages an obstacle on the terrain model.

Abstract: A golf club putter comprising a novel flat shaft having a width to be conveniently grasped by the user and having a head at its lower end with flat sides paralleling the flat sides of the shaft so that the club is adapted for left and right hand use and wherein a hand grip is provided at the upper end of the shaft with flat sides and having a series of finger-node indents spaced lengthwise of the shaft as guides for placement by the user of his fingers such that when a short putt is required the user places his lowest finger node on the lowermost indent and progressively places the lowest finger node into the next higher indents for longer putts.

Abstract: A golf club head is hollowed out to provide desired light weight characteristics. A tubular reinforcement material formed of plastic including reinforcement fibers, separate from the club head itself, is inserted into the cavity attached at the inner walls of the face and back, so as to span between them to prevent deformation of the head face and to hold the stiffness and mechanical strength required at its impact face.

Abstract: A slot machine has a plurality of reels, each having an annular series of various symbols on the periphery thereof and having, on a side thereof, a plurality of light shield plates different in shape from each other for distinguishing regions into which the reel is divided. Pulse signals for causing a pulse motor to rotate by an angle corresponding to each region are counted. A position of the reel either in rotation or stopped is determined based on the number of counted pulse signals and the region as distinguished by the detection of the shape of the associated light shield plate.

Abstract: Playing cards are marked with binary codes adjacent both side edges of the face of each card in a standard deck. The code includes a precode which signals a card reader to read the code in proper bit sequence depending on the direction of card movement past the reader. The binary code includes six bits to represent face value and suit of the card, and a four-bit error detection code which can detect errors of two bits in the code.A deck of coded cards is dealt either manually or automatically according to at least one predetermined program. The coded cards are passed over photocells which read the binary codes on the face of the card. The photocell outputs are sent to a microprocessor, which compares the code to the predetermined program and directs the card to the appropriate player location.

Abstract: The simulation device provides training in the firing of rockets or guided missiles by means of a shoulder weapon. As soon as a shot is fired, the firer's field of view is occulted by a shutter. The aim at the instant of firing and the point of impact with respect to the target are displayed on an instructor's video screen. The target can be of a fictitious type generated by a computer and produced within the field of view of both the instructor and the firer at the same time. In the case of a real target, an index can be controlled by the instructor in order to locate the target and follow its progress up to the instant of firing. The result of the firing operation is judged according to the position of the point of impact with respect to the fictitious target or with respect to the index. The choice of the mode of operation is made on a control desk.

Abstract: An electronic game in which the game participant fires a hand held target weapon at targets and must evade simulated return fire directed at the person of the participant from hazard weapons. The targets include lamps which are momentarily energized one at a time by timing circuitry. The target weapon includes a trigger switch and a photosensor for detecting when the target weapon is accurately aimed at an energized target. Digital displays indicate the number of shots remaining and the number of target hits that have been recorded by the participant. The hazard weapons emit infrared beams at the body of the game participant and are activated one at a time by timing circuitry. The game is terminated when the participant has expended all of the allotted shots at the targets or when the beam from an activated hazard weapon is intercepted by the person of the game participant.

Abstract: A body coordination training aid is presented for providing audio signals to a user in response to the user's head and shoulders assuming a predetermined relative orientation. This is accomplished via an electronic device responsive to a movable electrode contacting an adjustable electrode to complete an electrical circuit.

Abstract: A conveyer system is employed in a casino and transports a series of housings between a plurality of blackjack tables. The conveyer system is controlled such that the housings are randomly stopped at each table to enable a dealer to replace a depleted rack of cards with a new rack of cards contained in each of the housings. The conveyer system as controlled operates at any speed desired and randomly causes the housings coupled to the conveyer to be stopped at the tables so that a dealer, in accessing a new rack of cards contained in the housing, will replace the rack with the used rack. The system as depicted reduces cheating as by the use of marked cards and further reduces the time between deals as eliminating shuffling and repacking of the racks by the dealer.

Abstract: A pocket-sized electronic board game is disclosed. The apparatus for playing the game comprises a casing which serves also as the playing surface, through which project a plurality of push-buttons for actuating the keys in selected positions. A membrane-type key board may alternatively be used. The push-buttons and keys are arranged in a plurality of rows and columns with elongate light sources extending parallel to the rows of columns and between adjacent pairs of row-wise or column-wise keys. The electronic circuit within the casing acts to detect depression of two adjacent keys in any row or column and operates when such detection is made to cause the light source between the two actuated keys to illuminate and remain illuminated until the end of the game so that by depressing pairs of keys in turn players can "claim" sides of the squares constituted by the light sources.

Abstract: A flight simulator utilizes dual visual probes to simulate multisensor imry from a modelboard data base. The probes are mounted on a common gantry at a fixed relation to one another corresponding to their aircraft relation. One probe provides a wide angle visual presentation to the simulator cockpit, while the other provides a narrow field of view presentation modified and presented on a small screen CRT as a Forward Looking Infrared or other type display.

Abstract: A golf club has a shaft and a head for striking the ball, wherein the head has a generally polyhedral external shape widening out from the shaft. The head has at least three striking faces which have different angles of inclination and can be selected by turning the shaft. Beyond the striking faces, the head preferably has a generally flattened polyhedral shape with faces which support the head on the ground when using the different selectable striking faces.

Abstract: An improved golf club has a striking face which includes a central portion having an accentuated roll. The roll portion has a radius of curvature preferably between 1 inch and 0.70 inch. Grooves extend parallel to the accentuated roll portion on opposite sides thereof. An upper substantially flat surface extends along the striking face above the upper groove, and a lower substantially flat surface extends along the striking face below the lower groove. These surfaces reduce the effect of a mis-hit. The club face may also have a bulge with a radius of curvature of approximately 4 feet and a loft preferably between 8 and 18 degrees. The increased compression provided by the accentuated roll increases the distance of a drive by approximately ten percent.

Abstract: A radio-controlled teaching device comprising a teacher transmitter unit and a plurality of student receiver units for maintaining student alertness during oral reading of written textual material, for the oral administration of multiple-choice or true or false test material, and for the preparation and presentation of recorded programmed instructional material. The teacher transmitter unit contains a tone generator and radio transmitter which transmits discrete tone signals, either under manual control of the teacher or automatically under the control of a plural channel instructional tape recording. Each student receiver unit contains timers, a logic circuit, and a radio receiver which receives the above tone signals (which are transparent to the students) and provides a short time period during which the student is expected to respond by briefly closing a response switch. The short time periods correspond to portions of a text being orally read, such as the end of a paragraph, proper nouns, verbs, etc.
