摘要： A treadmill is disclosed having a belt system carried by a platform structure. The platform structure is pivotally mounted at its rear end to a base structure. The platform is supported at its forward end by a spring and a shock absorber which provides a damped resilient response of the belt and platform when a runner's foot lands during running or walking. The shock absorber is of the type which resists movement when the platform is moving in the downward direction, but offers relatively little resistance to upward movement of the platform when the spring returns the platform to a rest position during the time the runner is above the platform and is not forcing the platform down. An auxiliary shock absorber is mounted to damp the response of the platform over a short distance as the platform returns to its rest position.

摘要： A treadmill is disclosed having a belt system carried by a platform structure. The platform structure is pivotally mounted at its rear end to a base structure. The platform is supported at its forward end by a shock absorber/spring system which provides a damped resilient response of the belt and platform when a person's foot lands during running or walking. Carrying the belt system by the platform structure enables the endless belt of the belt system to be maintained closely above the platform even when a runner's foot lands on it with heavy impact. The support of the platform immediately below the belt eliminates lateral slack in the belt which could possibly result in injury to a walker or runner due to an uneven landing surface.

摘要： In order to provide a metal-to-metal annular seal for use in a high pressure environment typical of a wellhead assembly that is provided on a high pressure, high temperature gas well, especially circumferentially between the outside surface of a tubular part and the inside surface of a relatively massive part, where these parts are to have a fixed longitudinal position relative to one another in use: the available strength for developing the seal are determined; like tapering surfaces are provided on the two parts such as would provide an allowable interference fit when the two parts are brought to the fixed longitudinal position; portions of the outside surface of the tubular part are machined-away to leave tapered land areas, e.g. in two axially closely spaced bands, so that when the two parts are forced to assume the fixed longitudinal position, the seal bands provide an elastic seal that avoids total plastic deformation yet provide the required unit loading. The invention is useful on many types of frusto-conical sealing annuli.

摘要： A hydraulic control assembly especially suited for operation of a fail-safe valve. An integral structure is provided having a pair of check valves disposed in passageways extending from one chamber of a piston operator to a hydraulic reservoir and the other chamber of the piston reservoir, and in a fluid line extending from a high pressure source. In a fail-safe valve, cavity pressure normally acts on the valve stem and provides the force which moves the valve to its close position. A spring is disposed in the second chamber of the piston operator and, in conjunction with any force resulting from internal cavity pressure on the valve stem, aids in closing the valve. The second chamber is equal or greater in volume than the first chamber so that all of the hydraulic fluid displaced from the first chamber during valve closing can flow into the second chamber. In this way, the hydraulic power needed to pump hydraulic fluid back to the reservoir is not effected by installed hydraulic system variations. Additionally, these results are achieved while containing the fluid in a closed system. Fail-safe valves can be designed to either fail to the open or fail to the closed position.
摘要翻译：特别适用于故障安全阀操作的液压控制组件。提供一体的结构，其具有一对止回阀，该对止回阀设置在从活塞操作器的一个室延伸到液压储存器和活塞储存器的另一个室中以及从高压源延伸的流体管线的通道中。在故障安全阀中，腔体压力通常作用在阀杆上，并提供将阀移动到其关闭位置的力。弹簧设置在活塞操作器的第二腔室中，并结合由阀杆上的内腔压力产生的任何力，有助于关闭阀门。第二室的体积等于或大于第一室，使得在关阀期间从第一室移位的所有液压流体可流入第二室。以这种方式，将液压流体泵回到储存器所需的液压动力不受安装的液压系统变化的影响。另外，这些结果是在封闭系统中包含流体的同时实现的。故障安全阀可以设计成不能打开或不能到关闭位置。

摘要： The bearing assembly of a normally non-rising stem gate valve is provided with an annulus of fusible material. Upon subjection to a preselected temperature level, the fusible body melts out of the way, permitting the stem to raise slightly, making up a metal-to-metal seal between the valve stem and bonnet. This forms another line of defense against consequences from loss of the sealing normally provided by the valve stem packing.

摘要： A valve operator that is provided with a back seat which comes into use when the normally non-rising stem operator and its bearing-enclosing bonnet gland are raised, e.g. so that stem packing can be replaced, is further provided with another way to actuate the back seat, one which will come into play should the valve be subjected to heat of sufficient intensity as to call the integrity of the stem packing or other critical parts into question. The further activation mode depends on the melting of fusible material which permits the operator and its bearings to rise relative to the bonnet.

摘要： A valve operator for a normally open valve is maintained in a cocked, ready to close mode by an arrangement which includes a radially contracted, self-expansible split retainer ring backed by a body of fusible material. Should the vicinity of the associated valve be subjected to the heat of a fire, the fusible body will melt out of blocking relation, permitting the split ring to expand free of the operator stem. A cocked spring recovers, axially moving the stem both to shut the valve and to engage a metal-to-metal back seat between the valve stem and valve bonnet. The latter event ensures against leakage even if the fire or wear has ruined the integrity of the usual valve stem packing. The valve operator is further provided with a manual override which permits the valve to be closed and opened, e.g. using a remotely actuated pneumatic operator even while the body of fusible material remains intact and in place.
摘要翻译：用于常开阀的阀操作器通过包括由可熔材料体支撑的径向收缩的自膨胀分离保持环的装置保持在压缩的准备关闭模式。如果相关阀门的附近遭受火灾的热量，则熔体可能会熔化出阻塞关系，从而允许裂环扩展而不受操纵杆的影响。弹簧弹簧恢复，轴向移动阀杆以关闭阀门并且接合阀杆和阀盖之间的金属对金属后座。后一种事件即使火灾或磨损也破坏了通常的阀杆包装的完整性，也能防止泄漏。阀操作器还设置有手动超控，其允许阀被关闭和打开，例如，即使在易熔材料的主体保持原样并且到位的情况下，也使用远程致动的气动操纵器。

摘要： The control line exiting coupling provides radial penetration of a control line through a tubing hanger wall, with a back seat for sealing should internal pressure create a packing leak on the penetrator. The back seat further prevents withdrawal of the device through the packing and provides for withdrawing the control line tubing so the hanger may be removed from the wellhead without shearing off the control line tubing.

摘要： A non-rising valve stem is provided with a shoulder that, in normal opening and closing of the valve, remains free of a complementary seat formed inside the valve bonnet. Should the valve stem packing in the bonnet begin to leak while the valve is open and under pressure, the bonnet packing gland may be backed out a few turns to effect a seal between the shoulder and seat. Then a disassembly, packing change, reassembly and testing may be effected.
