Abstract: A wood stove is of all welded steel plate construction except for the door which is of heavy cast iron. When the door is closed, the only source of combustion air is through an adjustable air inlet on the face of the door. The door is hollow and serves to preheat the incoming air. The inner wall of the door divides the incoming air into lower and upper, primary and secondary, respectively, combustion air flows. The stove has an internal upper baffle running from rear to front which helps to promote air flow and combustion efficiency and to knock out entrained matter from the products of combustion. The flue connection is in the rear of the stove above the baffle and is stepped into the back of the stove to allow the stove to be fitted against a wall.

Abstract: A pre-step timer circuit for pre-advancing the next timer period (control step) in a DC motor controller, such as in a crane-hoist controller. A sensing resistor module is connected from the line side of a contactor coil of a preceding control step to the input of a timer module in series with the accelerating contactor coil in the next control step. This resistor module sensing the previous coil voltage provides a feed-forward path for the sensed voltage signal to pre-time the next timer module. So, if a master switch is left in the previous control step long enough for the next timer module to time out, then the next control step is actuated immediately when the master switch is advanced thereto.

Abstract: A dispenser for welding electrodes is disclosed. The dispenser comprises a tubular casing having a first internal elongate tubular cavity for storage of a plurality of the welding electrodes for dispensing one at a time therefrom. A top end closure has an axial opening dimensioned to permit the passage of one only of the electrodes from the cavity upon manual actuation of an axially-reciprocal pusher rod engaging the lower end of the electrode. The axial opening is provided with a friction grip disc which normally closes the opening, permits the passage of an electrode therethrough but exerts a friction grip on a stationary partly-dispensed electrode to prevent the same from returning to the cavity.
