Abstract: The present invention relates to a definition-word spelling game which is both educational and entertaining. The game uses a game board, a deck of cards, player pieces, letter-covering pieces, marker pieces and a chance device. The four sides of the game board are each defined by one of four different and distinct characteristic colors. The four player pieces, four sets of cards, four sets of cover tiles and four sets of markers are all similarly color coded. The board has four special function corners and each side between adjacent corners includes seven spaces for a total of 28. Each space includes a different and distinct letter of the alphabet with the remaining spaces being assigned special functions. A player landing on a given space, draws a card corresponding to the color on that section of the board the player is then read a definition of a word which normally starts with the letter on his given space.

Abstract: A resealable, anti-litter-type pop top beverage container wherein a rotatable tab member can be raised to depress a sealing member into the interior of the container to fully expose the lid opening for drinking or the like.

Abstract: A method and apparatus for synthesizing a set of optimal sensory stimuli designed to elicit an optimal response for each particular brain electrode location in a subject whose brain is being examined to anatomically localize brain dysfunction. A pseudorandom input signal having the general characteristics of Gaussian white noise is generated and converted into a color video visual stimulus which can be observed by the subject and summed on his retina and associated neural network. A plurality of electrodes are positioned with respect to various different and distinct areas of the brain of the subject to be examined. The subject is shown the color video visual stimulus and the electrical analog response from the electrodes is amplified and stored. The stored analog response signals are cross-correlated with the resynthesized input signal to compute a Wiener kernel representation of the response for each electrode.

Abstract: A method and apparatus for identifying a character which cannot be machine read so that an operator may observe the identified character and make the necessary correction. A document such as a bank check or the like which has a field of encoded characters thereon is moved along a transport path to a read station. When the read station is unable to identify a character, a "can't read" or reject signal is generated and this reject signal can be used to locate the identified character which cannot be machine read for later use. The document then proceeds to a marker station and when the reject character is properly positioned with respect to the printing station, a single wire dot printer mechanism is used to place a mark or dot above or below the character which could not be machine read or in some other suitable location which will positively identify the character which could not be machine read.

Abstract: A highly stable clothespin of the type having a pair of elongated clamping members and a helical metal spring interposed therebetween is provided. Each of the pair of clamping members has a forward clamping jaw, a tail, and an intermediate portion. The hollow body of the helical spring serves as a fulcrum about which the intermediate portions of the elongated clamping members are pivoted for opening and closing the jaws with respect to one another for gripping articles inserted therebetween. In a first embodiment, the improved stability is achieved by providing a lateral recess about the top surface and sides of each of the clamping members adjacent the fulcrum. An integral clip formed into a rectangular configuration is provided for each of the lateral recesses and the two ends of each of the clips are inserted into the hollow body of the spring for securing the clamping members thereto.

Abstract: D.C. power supply having a reactive buck automatic D.C. voltage regulator which directly controls the rectified D.C. output of a loosely coupled transformer thereby providing load regulation from an unregulated alternating current source. The load current passes through the secondary winding of an auxiliary buck transformer and is stepped down to a much lower value in the primary winding of the auxiliary buck transformer. The primary winding of the auxiliary buck transformer is coupled to an isolated winding on the core of a ferroresonant C.V.T. transformer which receives the unregulated alternating current input signal, and the coupling between the isolated winding and the primary winding of the buck transformer effects a bilateral energy transfer between the two transformers which effects a real time reactive compensation which regulates the D.C.

Abstract: A system for detecting the occurrence of a fault in a solenoid utilization system when the fault is manifested by the solenoid armature or plunger being seated either too early or too late. A predetermined time interval is established such that the seating of the solenoid armature or plunger during this time interval is regarded as acceptable. A cusp detector circuit detects the point in time at which the solenoid plunger or armature seats and if it is within this predetermined time interval, it is recognized as acceptable, but if it is detected either too early or too late, an indication is generated that a fault exists and the occurrence and probable nature of the fault may be flagged. A test mode is provided whereby the predetermined established time interval can be considerably narrowed so that maintenance can be performed on the system so as to insure that the solenoid armature or plunger seats at exactly the proper time.
