Automatic diametric dimension control for mill for rolling round bars

Abstract: A mill for rolling round bars, having a penultimate and a last stand with mutually perpendicular roll axes, is provided with a control system for varying the roll gaps of said stands and for axially aligning the rolls in the last stand. A gauge measures the diameters of the bar about its entire periphery and supplies a computer with this data. In addition, data, indicative of lengthwise variations in predetermined diameters of the bar, are supplied to the computer. The computer uses these data to compute an optimum diameter profile of the bar. The computer then calculates adjustments to the rolls in these last two stands to obtain this optimum profile. If substantial improvement in the performance of the mill can be obtained by these adjustments, the computer actuates means for adjusting these rolls whereby this profile may be realized.

Gas appliance with automatic gas shut-off device responsive to flame outage

Abstract: A gas appliance is provided for producing an open flame. The gas appliance includes an elongated gas tube, a gas inlet, a nozzle, a flame sensor, a gas shut-off valve, and a protective member. The gas tube has a proximal end and a distal end. The gas inlet is located near the proximal end, for connection to a source of combustible gas. The nozzle is located at the distal end, for expelling the combustible gas to produce the open flame. The flame sensor detects the open flame and communicates its absence or presence to the gas shut-off valve. The gas shut-off valve has a valve inlet, a valve outlet, a control input, and the over-ride mechanism. The valve inlet is connected to the gas inlet. The valve outlet is connected to the proximal end of the elongated gas tube. The control input is responsive to absence of the open flame as detected by the flame sensor so that the gas shut-off valve automatically closes when the flame is absent to keep the combustible gas from flowing from the valve inlet through the valve outlet. The over-ride mechanism is manually actuatable to over-ride the control input by opening the valve inlet to the valve outlet even if the flame is absent. The protective member is arranged around at least one of the flame sensor and the gas shut-off valve to protect these components. A method is provided for discharging combustible gas into the open flame in a manner dependent upon the presence of the open flame.
