Abstract
Abstract An arrangement for recording electrical pulses or pulse sequences on a storage device, preferably a magnetic tape or a magnetic foil driven by an electric motor. The pulses are produced by a pulse generator and transmitted to the storage device by a recording member. A switching circuit is provided to control the energization of the electric motor and is controlled by a control circuit coupled both to the switching circuit and the pulse generator so that at the beginning of the first pulse, the switching circuit effects an energization of the motor and deenergizes the motor only after the expiration of a predetermined constant interval of time following the last to occur pulse in the pulse sequence.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
281 words
A signal recording arrangement for recording signals from an actuating device which passes through different datum positions, comprising: electrical signal storage means; an electric motor for driving said storage means; pulse generator means responsive to said actuating device for producing electrical pulses or pulse sequences, said pulses being transmitted to said storage means by means of a recording member; means defining a capacitor charging circuit including a chargeable capacitor and energy source means for energizing said capacitor charging circuit and charging said chargeable capacitor to a fully charged condition prior to the generation of said electrical pulses or pulse sequences; means defining a discharge circuit for discharging said capacitor, said discharge circuit means being responsive to said electrical pulses or pulse sequences from said pulse generator means to effect a discharge of said capacitor immediately upon receipt; regenerative bistable circuit means normally in one of two conditions and producing a first output signal in response to a discharge of said capacitor caused by a change of condition of said regenerative bistable circuit means to the other condition, said regenerative bistable circuit means being also responsive to a charging of said capacitor to return said regenerative bistable circuit means to said one condition to effect a generation of a second output signal; and switching means connected to said motor and adapted to effect a control on the energization of said motor, said switching means being responsive to said first and second output signals from said regenerative bistable circuit means to turn said motor completely on and completely off, the time period for charging said capacitor determining a constant time interval between two different pulses or series of pulses in said storage means.

Claim 3
Dependent Claim
51 words
The improvement according to claim 1, wherein said switching means comprises a transistor connected in circuit with said electric motor, said regenerative bistable circuit means effecting a control on said transistor by rendering it alternately completely conductive and completely nonconductive, said regenerative bistable circuit means including an adjustable time delay period.
Claim 4
Dependent Claim
88 words
