Abstract
Abstract A selector for apparatus for automatically playing back information comprising a keyboard (11) used in formulating a selection and co-operating with a store (14) and a panel (15) for displaying signs corresponding to those identifying the keys which have been pressed. The numbers, words or combinations can be stored in sequence and in the order in which they have been formulated. An input register (16) is disposed between the keyboard (11) and the store (14) and is adapted to receive a complex selection so that the latter can be checked before insertion into the store. (FIG. 1).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
139 words
In a selector for devices for automatically playing back information, the combination of: a keyboard having keys identified by digits or letters, said keys being adapted to form, by pressing thereof, a number, word or name, or a combination of digits and letters; a circulating store; and a display panel cooperating with said store and with the keyboard so that the combination of digits and letters corresponding to the keys which have been pressed in the keyboard are stored and the number, words, and the like, sequentially appear in the display panel in the order in which they have been formulated, and are adapted to be extracted one after another; and an output register for receiving and retaining during the full time required for processing the selection one of the selections whose coordinates have been extracted from the store.
Claim 2
Dependent Claim
139 words
In a selector for devices for automatically playing back information, the combination of: a keyboard having keys identified by digits or letters, said keys being adapted to form, by pressing thereof, a number, word or name, or a combination of digits and letters; a circulating store; and a display panel cooperating with said store and with the keyboard so that the combination of digits and letters corresponding to the keys which have been pressed in the keyboard are stored and the number, words, and the like, sequentially appear in the display panel in the order in which they have been formulated, and are adapted to be extracted one after another; and an output register for receiving and retaining during the full time required for processing the selection one of the selections whose coordinates have been extracted from the store.
Claim 3
Dependent Claim
31 words
A selector according to claim 1, comprising means for conveying a new selection immediately into said output register from said store upon said output register being emptied from a preceding selection.
Claim 4
Dependent Claim
44 words
A selector according to claim 1, comprising a buffer current accumulator for supplying said store, said accumulator adapted to be recharged during normal operation of the selector, whereby upon power failure or intermittent disconnection of the device, the selections in said store remain undiSturbed.
Claim 5
Dependent Claim
56 words
A selector according to claim 1, comprising a cathode screen for reading and checking the digits in said input register, an input key of said keyboard adapted to be pressed for introducing the number formed into a free space in said circulating store; and a free-position detector element for determining said free place in said store.
Claim 6
Dependent Claim
121 words
A selector according to claim 4, said circulating store comprising 176 binary positions or 10 six-digit words (10 words of four decimal digits) and a 16 digit word ''''one'''' (1) forming the first part of a message and, upon an input order being given by pressing a key of said keyboard, the 16 items of binary information in said input register are adapted to slide in series into the first group of sixteen free positions in the circulating store; a unit of logic operators being adapted to control the last-mentioned operation registers the results supplied to a detector for the first part of the message and the free-position detector (23); and a time control unit for synchronizing all of said operations.
Claim 7
Dependent Claim
32 words
A selector according to claim 1, the first selection in said store being indicated in a first line therein, said selection being the same as the selection given in the output register.
Claim 8
Dependent Claim
50 words
A selector according to claim 4, comprising an electron beam tube emanating an election beam each time an item of coded information appears in order to be displayed, and generating other items of information adapted to deflect the electron beam so as to each time form the appropriate scanning curve.
