摘要： An anti-reverse flow and syphon breaker valve assembly as a replacement for the valve and valve stem assembly of the conventional bibcock, hose bibs and faucets having a pair of telescopically mounted valve stems, one valve stem having a bore forming a guide for the main valve stem and the bore receiving a relatively light coil spring yieldingly urging the main valve to seat on the valve seat whereby upon threading the main valve to its open position, the pressure of water slides the main valve against the spring pressure to its open position and upon loss of water pressure or upon creation of a syphon effect the main valve is brought to its closed position instantaneously to prevent a reverse flow of water.

摘要： A variable resistor unit particularly useful in selectively controlling current in a circuit of low or medium voltage, a preferred form of the invention includes a smooth bore resistance coil having a helical wire contact element convolutely arranged in the bore of the resistance coil structure of the device. A ring of metallic mercury fluid is concentrically arranged in the bore of the resistance coil and defines adjustable contact means engaging the contact areas of the helical coil element. Selective axial manipulation of the mercury ring in the bore of the resistance coil operatively increases or decreases the resistance in the circuit of the resistor device.

摘要： Apparatus for transversely cutting and severing lengths of pipe or rod work stock material and having a tubular frame adapted to endwise receive a length of pipe stock to be cut. A plurality of clamping jaw assemblies is stationarily supported in radial arrangement on the tubular frame and provides spring-loaded jaw means radially projecting into the tubular frame interior for clamping and centering the pipe work stock in the tubular frame. A cutter head having radially arranged cutter jaw assemblies is supported on one end of the tubular frame and is rotatingly driven to form a groove around the pipe wall for severing the pipe stock at the grooved portion. A crowder element having frustoconical interior cam surface means is movably mounted concentrically on the tubular frame and is adapted for translational movement longitudinally of the frame. Movement of the crowder element in one direction is operative through the frustoconical cam surface means thereof for simultaneously causing radial endward movement of the plurality of clamping jaws and the plurality of cutting jaws for respectively clamping and cutting the pipe stock material. Movement of the crowder element in the opposite direction is operative for causing radial outward movement of the plurality of clamping and cutting jaws and for releasing the pipe stock from the tubular frame of the cutting apparatus.

摘要翻译： 用于横向切割和切断管或棒材料材料的长度的装置，并且具有适于端接地接收要切割的管材长度的管状框架。 多个夹紧爪组件以管状框架的径向方式固定地支撑，并且提供弹簧加载的夹爪装置径向突出到管状框架内部，用于夹紧和定心管状工件在管状框架中。 具有径向布置的切割爪组件的刀头被支撑在管状框架的一端上并被旋转地驱动以在管壁周围形成用于在槽部分处切断管材的槽。 具有截头圆锥形内部凸轮表面装置的较为激烈的元件可同心地安装在管状框架上并且适于在框架的纵向平移运动。 挤压元件在一个方向上的运动通过截头圆锥凸轮表面装置工作，以同时引起多个夹爪和多个切割爪的径向向内运动，以分别夹紧和切割管材料。 相反方向上的挤压元件的运动用于使多个夹紧和切割爪的径向向外移动并且用于将管材从切割装置的管状框架释放。

摘要： A HYDRAULIC ASSEMBLY FOR FILLING AND RAPIDLY DISCHARGING A LIQUID FROM A HERMETICALLY SEALED TANK. VERTICALLY POSITIONED IN THE TANK IS A CHUTE HAVING AN OPEN LOWER END AND A CLOSED UPPER END AND HAVING AN APERTURE OPENING INTO THE LOWER PORTION OF THE TANK. A VALVE SEAT EXTENDS AROUND THE INNER PERIPHERY OF THE CHUTE POSITIONED BELOW THIS APERTURE, WHILE POSITIONED WITHIN THE CHUTE IS A VALVE HEAD WITH A STEM. THE VALVE HEAD IS CAPABLE OF VERTICAL MOVEMENT FROM AN OPEN POSITION ABOVE THE APERTURE TO A CLOSED POSITION IN SEALED ENGAGEMENT WITH THE SEAT. ON THE VALVE STEM IS A ROLLING DIAPHRAGM DISPOSED FOR VERTICAL MOVEMENT IN THE CHUTE. MANUAL MEANS ARE ASSOCIATED WITH THE STEM FOR MOVING THE VALVE HEAD FROM THE CLOSED TO THE OPEN POSITION, AND SPRING MEANS, NORMALLY RESISTING UPWARD MOVEMENT OF THE VALVE HEAD WHEN

THE VALVE HEAD IS SEATED, ARE DISPOSED ABOVE THE ROLLING DIAPHRAGM AROUND SAID STEM. THERE IS ALSO AN AIR VENT AND CHECK VALVE PASSING THROUGH THE TANK. THE CHECK VALVE MOVES TO A CLOSED POSITION WHEN LIQUID IN THE TANK RISES TO A PREDETERMINED LEVEL AND FALLING TO OPEN THE VENT TO THE ATMOSPHERE WHEN LIQUID FALLS BELOW THIS LEVEL. PRESSURIZED WATER IS SUPPLIED INTO THE TANK BY AN INLET CONDUIT. OPERATION OF THE MANUAL MEANS WILL OPEN THE VALVE HEAD, FORCING THE LIQUID TO FLOW THROUGH THE APERTURE AND OUTWARDS FROM THE CYLINDER, THE FLOW THEREOF BEING AUGMENTED BY COMPRESSED AIR PRESSURE ACTING TO RAPIDLY FORCE LIQUID THROUGH THE APERTURE AND OUT OF THE CYLINDER.

摘要： A CLOSED CONTAINER FOR RECEIVING AND RETAINING A PREDETERMINED QUANTITY OF PRESSURIZED WATER INCLUDING A CYLINDER WITH AN APERTURE OPENING INTO THE TANK AND A FLUSHING VALVE AT THE LOWER PORTION OF THE CYLINDER. A PISTON IN SAID CYLINDER ABOVE SAID APERTURE FOR UPWARD MOVEMENT BY PRESSURE FOR COMPRESSING A SPRING WHEN THE CONTAINER IS FILLED WITH PRESSURIZED WATER FOR AIDING THE RAPID DISCHARGE OF WATER FROM THE CYLINDER WHEN THE FLUSHING VALVE IS OPENED.
