Abstract
Abstract A circuit arrangement having contacts which can be operated, a ring counter having outputs corresponding to the contacts and for each contact a gating circuit controlled by this contact and the corresponding ring counter output. When the contact is operated the corresponding gating circuit supplies a signal which causes the ring counter to count until the position of the ring counter is in conformity with the operated contact.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
139 words
A circuit arrangement having a plurality of touch contacts, and outputs corresponding thereto, in which in response to an instantaneous operation of one of the contacts the output corresponding thereto continously assumes an operating condition and the other outputs assume a rest condition, said circuit arrangement comprising a ring counter having outputs constituting of said outputs of the circuit arrangement, characterized by a number of gates which are each controlled by one of the contact and the corresponding output of the ring counter and are able to supply a gateoutput signal if the contact connected thereto is operated and the ring counter output connected thereto is in the rest condition, and means controlled by said gates for applying counting pulses to the ring counter if and as long as one of the said gates supplies the said gate-output signal.
Claim 2
Dependent Claim
139 words
A circuit arrangement having a plurality of touch contacts, and outputs corresponding thereto, in which in response to an instantaneous operation of one of the contacts the output corresponding thereto continously assumes an operating condition and the other outputs assume a rest condition, said circuit arrangement comprising a ring counter having outputs constituting of said outputs of the circuit arrangement, characterized by a number of gates which are each controlled by one of the contact and the corresponding output of the ring counter and are able to supply a gateoutput signal if the contact connected thereto is operated and the ring counter output connected thereto is in the rest condition, and means controlled by said gates for applying counting pulses to the ring counter if and as long as one of the said gates supplies the said gate-output signal.
Claim 3
Dependent Claim
122 words
A circuit arrangement as claimed in claim 1 in which the outputs of the ring counter in the rest condition have a high resistive connection and in the operating condition have a low resistive connection to a common reference point (ground), characterized in that each of the gates has a first element connected to the corresponding output of the ring counter through which element a current flows which is generated when the corresponding contact is operated if said output of the ring counter is in the operating condition, as well as a second element through which said current flows to the means for applying counting pulses to the ring counter if said output of the ring counter is in the rest condition.
Claim 4
Dependent Claim
28 words
A circuit arrangement as claimed in claim 2, characterized in that the first element is constituted by a diode and the second element is constituted by a resistor.
Claim 5
Dependent Claim
128 words
A circuit arrangement for a plurality of touch contacts, said circuit comprising a ring counter having a plurality of output means corresponding thereto for responding to an instantaneous operation of the respective contact and for continuously aSsuming an operating condition and wherein the other output means assume a rest condition, a number of gate means coupled to and controlled by one of the contacts and the corresponding output of the ring counter for supplying a gate output signal if the contact thereto is operated and the ring counter output coupled thereto is in the rest condition, and means coupled to and controlled by said gates for applying counting pulses to the ring counter if and as long as one of the said gates supplies the said gate-output signal.
Claim 6
Dependent Claim
128 words
A circuit arrangement for a plurality of touch contacts, said circuit comprising a ring counter having a plurality of output means corresponding thereto for responding to an instantaneous operation of the respective contact and for continuously aSsuming an operating condition and wherein the other output means assume a rest condition, a number of gate means coupled to and controlled by one of the contacts and the corresponding output of the ring counter for supplying a gate output signal if the contact thereto is operated and the ring counter output coupled thereto is in the rest condition, and means coupled to and controlled by said gates for applying counting pulses to the ring counter if and as long as one of the said gates supplies the said gate-output signal.
Claim 7
Dependent Claim
115 words
A circuit arrangement as claimed in claim 4 in which the outputs of the ring counter in the rest condition have a high resistive connection and in the operating condition have a low resistive connection to a common reference point, each of the gates having a first element means coupled to the corresponding output of the ring counter for passing a current which is generated when the corresponding contact is operated if said output of the ring counter is in the operating condition, and a second element means for passing said current to the means for applying counting pulses to the ring counter if said output of the ring counter is in the rest condition.
Claim 8
Dependent Claim
22 words
A circuit arrangement as claimed in claim 5, wherein the first element comprises a diode and the second element comprises a resistor.
