摘要： A motor-driven electric cable reel assembly includes a rotatable cable take-up drum, and an electric motor for driving the drum in a cable take-up direction. The cable reel assembly also includes a storage battery provided with a battery charger which is connected to the cable in a manner such that the battery is recharged when the cable is connected to an electric power source. Also provided is a switch arrangement which stops the motor in response to torque generated by the motor.

摘要： An indicator mounted on a receptacle for determining the proportion of the liquid mixture components in the receptacle of a liquid dispensing apparatus, such as a rug or carpet shampoo device. Even if the receptacle is partly filled with a liquid mixture, the present indicator shows the correct amount to be added to each of the components to thereby fill the receptacle to a given level.

摘要： A control circuit for a motor includes a thyristor connected to apply current to the motor, and a phase shift circuit for controlling the thyristor including a series RC circuit connected in parallel with the thyristor. The junction of the resistor and capacitor is connected to the control electrode of the thyristor. A transformer has a primary winding connected in parallel with the capacitor, and a variable resistor, which may be remotely located, connected in series with the secondary winding, for varying the phase shift of the phase shift circuit.
