A number game comprising a plurality of tiles and a tile support means having an intersecting pattern of one row and one column of tile receiving spaces is disclosed. The object of the game is to determine the mathematical number combinations chosen by the other players to fill their tile support means.

A number puzzle is provided wherein a series of nine tiles, numbered 1-9 in seriatim are arranged in a 3.times.3 relationship and slidably disposed in one recess of a housing, with the housing having an auxiliary recess to accommodate one of the tiles so as to slidably move the other tiles. The object of the game is to arrange the tiles so that when the numbers are added horizontally, vertically or diagonally, the sum is "15".

Hydrocarbon fuels with an improved cetane number are obtained by blending a liquid fuel with a cyclic ether compound. Cyclic ethers are compounds which have a ring structure of carbon and a minor number of oxygen atoms, including beta-lactones and adducts of the beta-lactones with aldehydes or ketones.

The present invention relates to a two-way translator arrangement for an automatic switching system including n groups of substation lines, each of the n group including a plurality of substation lines, certain ones of the plurality of lines being normal lines having a normal class-of-service and whose directory and equipment numbers are associated by a predetermined systematic relationship and special lines whose directory and equipment numbers are not so associated and/or which have a special ...

A number translator which includes a memory system for storing directory and equipment numbers as well as other subscriber data has a digit store for storing data received from a register prior to its being passed on to the memory system, a register sender control for controlling the sending of data from the memory system to the register and a translator control for controlling both the digit storage and the sender control. The number translator further includes a route translation circuit by wh...

A compactly stored word list that includes a directed graph data structure is used for word to number (W/N) and number to word (N/W) mapping. Each word accepted by the data structure is mapped to a unique corresponding number within a dense set of numbers ranging from zero to one less than the total number of acceptable words. Some common suffixes are collapsed into shared branches, which is possible because the numbers are not stored within the word list. In addition, some branches of the data ...

A telephone sequential dialer features a shift register which has a number of bit positions which are one more than the maximum number of digits to be dialed. A plurality of consecutive ONES starting at the leading edge of the shift register are inserted into it, the number of ONES inserted being equal to the difference between the number of shift register bit positions and the number of digits of the telephone number to be called. The digits of the telephone number to be called are inserted int...

A binary-to-decimal converter comprises a plurality of cascaded adding means having order numbers n=1,2,3... wherein the binary number is initially received by the adding means with order number 1 and proceeds serially through the adding means. The first adding means adding 1 to the binary number and each subsequent adding means multiplying the result from the previous adding means by ##SPC1## Further means return the result from the last adding means to the input of the first adding means until...

An automatic, portable digit outpulser for use with a telephone is disclosed. In one preferred embodiment, the outpulser resembles a credit card encasing electronic circuitry and having a low-profile acoustic device mounted on one surface of the card for acoustically coupling the outpulser to the transmitter of a telephone. Optical and mechanical coupling arrangements are also disclosed. The electronic circuitry includes a memory for storing representations of telephone digits to be outpulsed an...
