Claim 2

IN A STOCK TRANSACTION INFORMATION SYSTEM, A MANUALLY OPERABLE STOCK SELECTOR DEVICE FOR ESTABLISHING COMBINATIONS OF ELECTRICAL SIGNALS REPRESENTATIVE OF PLURALITIES OF STOCKS, SAID DEVICE COMPRISING A PLURALITY OF MANUALLY ROTATABLE MEMBERS EACH HAVING A PLURALITY OF TRACKS WITH A PLURALITY OF SIGNAL CONTROL ELEMENTS IN EACH TRACK, SAID CONTROL ELEMENTS OF THE TRACKS OF EACH ROTATABLE MEMBER BEING ARRANGED IN A PLURALITY OF COMBINATORIAL GROUPS DEPENDENT UPON THE POSITION OF ROTATION OF THE RESPECTIVE MEMBER, SIGNAL PRODUCING MEANS INDIVIDUALLY ASSOCIATED WITH SAID TRACKS OF EACH ROTATABLE MEMBER AND ARRANGED FOR DERIVING PARALLEL COMBINATIONS OF SIGNALS IN ACCORDANCE WITH THE SIGNAL CONTROL ELEMENT COMBINATORIAL GROUPS THEREOF, AND INDICIA FOR EACH OF SAID ROTATABLE MEMBERS TO REPRESENT EACH OF SAID COMBINATORIAL GROUPS BY AN ALPHABETIC CHARACTER.

Claim 3

A MANUALLY OPERABLE SELECTOR DEVICE COMPRISING A PLURALITY OF ROTATABLE MEMBERS EACH BEING MANUALLY OPERABLE AND HAVING DETENT AND SIGNAL-PRODUCING PORTIONS, A PLURALITY OF MANUALLY OPERABLE PUSH-BUTTON SWITCH ACTUATORS, A LATCH FOR RELEASABLY RETAINING SAID ACTUATORS IN ACTUATED POSITION, AND DETENT MEANS FOR ENGAGING SAID DETENT PORTIONS TO RELEASABLY RETAIN SAID ROTATABLE MEMBERS IN CERTAIN ROTARY POSITIONS, SAID DETENT MEANS INCLUDING MEANS FOR RELEASING SAID ACTUATOR LATCH UPON A CHANGE IN ROTARY POSITION OF ANY OF SAID ROTATABLE MEMBERS.

Claim 4

A MANUALLY OPERABLE SELECTOR DEVICE COMPRISING A PLURALITY OF ROTATABLE MEMBERS EACH BEING MANUALLY OPERABLE AND HAVING DETENT AND SIGNAL-PRODUCING PORTIONS, A PLURALITY OF MANUALLY OPERABLE PUSH-BUTTON SWITCH ACTUATORS, A LATCH FOR RELEASABLY RETAINING SAID ACTUATORS IN ACTUATED POSITION, AND DETENT MEANS FOR ENGAGING SAID DETENT PORTIONS TO RELEASABLY RETAIN SAID ROTATABLE MEMBERS IN CERTAIN ROTARY POSITIONS, SAID DETENT MEANS INCLUDING MEANS FOR RELEASING SAID ACTUATOR LATCH UPON A CHANGE IN ROTARY POSITION OF ANY OF SAID ROTATABLE MEMBERS.

Claim 5

IN A STOCK INFORMATION SYSTEM COMPRISING A CYCLIC MEMORY FOR STORING SIGNAL COMBINATIONS REPRESENTATIVE OF NUMERICAL STOCK INFORMATION IN ACCORDANCE WITH SIGNAL STORAGE ADDRESSES CORRESPONDING TO A MULTI-CHARACTER STOCK IDENTIFIER CODE IN WHICH EACH CHARACTER IS FORMED AS A COMBINATION OF IDENTIFIER SWITCHING SIGNALS AND TO INFORMATION CATEGORIES EACH CORRESPONDING TO A DIFFERENT CATEGORY SWITCHING SIGNAL, AND MEANS FOR OBTAINING INFORMATION SIGNAL COMBINATIONS FROM SAID MEMORY IN ACCORDANCE WITH SAID IDENTIFIER AND CATEGORY SWITCHING SIGNALS; A MANUALLY OPERABLE CONSOLE INCLUDING SEVERAL PLURALITIES OF SETTABLE SWITCHES, EACH OF SAID SWITCH PLURALITIES CORRESPONDING TO A RESPECTIVE CHARACTER OF SAID MULTI-CHARACTER STOCK IDENTIFIER CODE, SEPARATE MANUALLY OPERABLE MEANS FOR SELECTIVELY ACTUATING AND LATCHING EACH PLURALITY OF SWITCHES COMBINATORIALLY TO ESTABLISH DIFFERENT ONES OF SAID IDENTIFIER SWITCHING SIGNAL COMBINATIONS AND FOR INDICATING THE CHARACTER CORRESPONDING TO THE SETTINGS OF THE RESPECTIVE PLURALITY OF SWITCHES, A PLURALITY OF SETTABLE SWITCHES EACH CORRESPONDING TO A DIFFERENT ONE OF SAID INFORMATION CATEGORIES, SEPARATE MANUALLY OPERABLE MEANS FOR SELECTIVELY ACTUATING AND LATCHING SAID CATEGORY SWITCHES AND FOR INDICATING THE CATEGORY CORRESPONDING TO THE SETTING THEREOF, AND A PLURALITY OF SELECTIVELY CHANGEABLE NUMERICAL DISPLAY DEVICES EACH HAVING MEANS FOR DISPLAYING ALL OF THE NUMERICAL DIGITS AND RESPONSIVE TO VARIOUS ONES OF SAID INFORMATION SIGNALS COMBINATIONS FOR DISPLAYING CORRESPONDING ONES OF THE NUMERICAL DIGITS, SAID DISPLAY DEVICES AND INDICATING MEANS BEING ADJACENTLY LOCATED ON SAID CONSOLE FOR CONCURRENT VIEWING BY AN OPERATOR, WHEREBY THE OPERATOR CAN RELATE THE DISPLAYED INFORMATION TO THE SWITCH SETTINGS.

Claim 6

IN A STOCK INFORMATION SYSTEM COMPRISING A CYCLIC MEMORY FOR STORING SIGNAL COMBINATIONS REPRESENTATIVE OF NUMERICAL STOCK INFORMATION IN ACCORDANCE WITH SIGNAL STORAGE ADDRESSES CORRESPONDING TO A MULTI-CHARACTER STOCK IDENTIFIER CODE IN WHICH EACH CHARACTER IS FORMED AS A COMBINATION OF IDENTIFIER SWITCHING SIGNALS AND TO INFORMATION CATEGORIES EACH CORRESPONDING TO A DIFFERENT CATEGORY SWITCHING SIGNAL, AND MEANS FOR OBTAINING INFORMATION SIGNAL COMBINATIONS FROM SAID MEMORY IN ACCORDANCE WITH SAID IDENTIFIER AND CATEGORY SWITCHING SIGNALS; A MANUALLY OPERABLE CONSOLE INCLUDING SEVERAL PLURALITIES OF SETTABLE SWITCHES, EACH OF SAID SWITCH PLURALITIES CORRESPONDING TO A RESPECTIVE CHARACTER OF SAID MULTI-CHARACTER STOCK IDENTIFIER CODE, SEPARATE MANUALLY OPERABLE MEANS FOR SELECTIVELY ACTUATING AND LATCHING EACH PLURALITY OF SWITCHES COMBINATORIALLY TO ESTABLISH DIFFERENT ONES OF SAID IDENTIFIER SWITCHING SIGNAL COMBINATIONS AND FOR INDICATING THE CHARACTER CORRESPONDING TO THE SETTINGS OF THE RESPECTIVE PLURALITY OF SWITCHES, A PLURALITY OF SETTABLE SWITCHES EACH CORRESPONDING TO A DIFFERENT ONE OF SAID INFORMATION CATEGORIES, SEPARATE MANUALLY OPERABLE MEANS FOR SELECTIVELY ACTUATING AND LATCHING SAID CATEGORY SWITCHES AND FOR INDICATING THE CATEGORY CORRESPONDING TO THE SETTING THEREOF, AND A PLURALITY OF SELECTIVELY CHANGEABLE NUMERICAL DISPLAY DEVICES EACH HAVING MEANS FOR DISPLAYING ALL OF THE NUMERICAL DIGITS AND RESPONSIVE TO VARIOUS ONES OF SAID INFORMATION SIGNALS COMBINATIONS FOR DISPLAYING CORRESPONDING ONES OF THE NUMERICAL DIGITS, SAID DISPLAY DEVICES AND INDICATING MEANS BEING ADJACENTLY LOCATED ON SAID CONSOLE FOR CONCURRENT VIEWING BY AN OPERATOR, WHEREBY THE OPERATOR CAN RELATE THE DISPLAYED INFORMATION TO THE SWITCH SETTINGS.
