    摘要： A BURNER FOR HEATING METAL IN A FURNACE OR THE LIKE INCLUDING A BODY MEMBER HAVING AIR AND GAS METERING ORIFICES THEREIN, A TILE HAVING AXIALLY EXTENDING SECONDARY COMBUSTION CHAMBER THEREIN, A TILE MOUNTING MEMBER SECURED TO ONE END OF THE TILE PROVIDING A PRIMARY COMBUSTION CHAMBER FOR THE BURNER AND HAVING AXIALLY EXTENDING OPENINGS WITH SLANTED SIDES THERETHROUGH EXTENDING INTO THE PRIMARY COMBUSTION CHAMBER AND THE SECONDARY COMBUSTION CHAMBER IN THE TILE, AND A GASKET POSITIONED BETWEEN THE BODY MEMBER AND TILE MOUNTING MEMBER FOR DIRECTING PRIMARY AND SECONDARY AIR THROUGH THE TILE MOUNTING MEMBER OPENINGS INTO THE COMBUSTION CHAMBERS IN A RATIO DEPENDING ON THE AREA OF THE OPENINGS AND IMPARTING A SWIRL TO THE AIR IN ACCORDANCE WITH THE ALIGNMENT OF THE OPENINGS THROUGH THE GASKET AND THE OPENINGS THROUGH THE TILE MOUNTING MEMBER. UPSTREAM AND DOWNSTREAM PRESSURE TAPS ARE PROVIDED IN THE BODY MEMBER FOR ASCERTAINING AIR AND GAS FLOWS. A FLAT ANNULAR MEMBER HAVING OPENINGS THERETHROUGH IS POSITIONED BETWEEN THE SECONDARY AIR AND THE SECONDARY COMBUSTION CHAMBER IN ONE MODIFICATION OF THE BURNER DISCLOSED TO STABILIZER THE BURNER FLAME. THE BURNER MAY BE MOUNTED IN THE ROOF, HEARTH OR THE WALL OF A FURNACE AND WHEN MOUNTED IN THE WALL OF A FURNACE, A VENTURI TILE MAY BE POSITIONED AXIALLY OF THE BURNER TO INSURE HIGH ENTRAINMENT AND RECIRCULATION OF FURNACE GASES.

    摘要： Safety shutoff valve structure and method, wherein the valve is a ball valve sealed by an annular flexible seal urged into engagement with the valve by a garter spring whereby on opening the valve substantially no pressure drop is developed across the valve, and wherein a compression spring is provided for urging the valve stem in one direction to close the valve, a lever and detent means therefor are connected to the valve stem by a solenoid actuated spring clutch responsive to a predetermined condition whereby on rotating the valve stem to place the valve in an open position, the valve is maintained in the open position until occurrence of the predetermined condition. The spring clutch is operated with a uniform force not dependent on the valve opening torque or compression spring strength and the spring clutch is engaged with a force greater than the actuating force on moving the valve to an open position.

    摘要翻译： 安全截止阀结构和方法，其中所述阀是由环形柔性密封件密封的球阀，所述环形柔性密封件通过扭矩弹簧推动与所述阀接合，由此在打开所述阀时基本上不跨所述阀产生压降，并且其中压缩弹簧 被设置成用于沿一个方向推动阀杆以关闭阀，其杠杆和止动装置通过响应于预定条件的螺线管致动的弹簧离合器连接到阀杆，由此在旋转阀杆以将阀置于 打开位置时，阀门保持在打开位置，直到出现预定条件。 弹簧离合器以不依赖于阀开启扭矩或压缩弹簧强度的均匀力来操作，并且当将阀移动到打开位置时，弹簧离合器与大于致动力的力接合。
