Abstract

1,093,936. Automatic exchange systems. ERICSSON TELEPHONES Ltd. Nov. 16, 1964, No. 46644/64. Heading H4K. A number sending arrangement comprises a set of push-buttons one for each digit value and a set of four capacitors for each digit which are charged in different combinations according to the digit value, with a sequence train of bistable circuits for connecting up the sets of capacitors in turn to store the digits selected. A further bi-stable circuit ensures that no pushbutton is effective until a previously operated push-button is released. The stores may be associated with the impulse sender described in Specification 1,093,184.
