摘要： An excess pressure and/or excess flow/temperature shutoff valve comprising a valve housing having an axial bore therethrough with inlet and outlet ends, a portion of the bore being enlarged to form a valve chamber, and a spool movable in the valve chamber and having a sealing fit with the walls of the chamber. In the event of an upstream pressure increase of predetermined magnitude, the spool is adapted to move from an open position in which it permits flow of fluid through the bore to a position wherein additional spool area is exposed to the upstream fluid pressure, whereupon the spool is adapted to move further downstream to a shut off position for blocking the flow of fluid through the bore. The valve may be optionally equipped to shut off the flow of fluid in the event of a downstream pressure decrease as a result of excess leakage and/or an increase in fluid temperature in excess of a predetermined value.
摘要翻译：一种过量的压力和/或过量的流量/温度截止阀，其包括阀壳体，其具有穿过其的入口和出口端的轴向孔，孔的一部分被扩大以形成阀室，以及可在阀室中移动并具有与腔室的壁密封配合。在上游压力增加预定大小的情况下，阀芯适于从打开位置移动，其中允许流体通过孔流动到其中附加的卷轴区域暴露于上游流体压力的位置，于是该卷轴适于在下游进一步移动到关闭位置，以阻止通过孔的流体流动。可选地，阀可以在由于过量泄漏和/或超过预定值的流体温度的增加而导致下游压力降低的情况下切断流体流动。

摘要： A pneumatic oxygen conserver used with a single-tube cannula. The conserver includes a body having first and second cavities. A main diaphragm divides the first cavity into first and second chambers. An inlet passage delivers oxygen from a supply to the first chamber, and an outlet passage delivers oxygen from the first chamber to the cannula. The main diaphragm is movable between a closed position preventing oxygen flow through the outlet passage and an open position permitting flow. A first flow control passage connects the inlet passage and the second chamber, and a first flow control orifice in the passage restricts flow. A sensing diaphragm divides the second cavity into third and fourth chambers. A second flow control passage connects the second and third chambers, and a second flow control orifice in the passage restricts flow. The sensing diaphragm is movable between a closed position preventing flow through the second passage and an open position permitting such flow. A vent passage vents the third chamber. A sensing passage connects the outlet passage and the fourth chamber. Inhalation into the cannula moves the sensing diaphragm to its open position to vent the second and third chambers causing the main diaphragm to move to its open position for delivering oxygen to the cannula.
摘要翻译：与单管插管一起使用的气动氧气保护器。保护器包括具有第一和第二腔的主体。主隔膜将第一腔分隔成第一和第二腔室。入口通道将氧气从供应源输送到第一室，并且出口通道将氧气从第一室输送到套管。主隔膜可在闭合位置之间移动，防止通过出口通道的氧气流动和允许流动的打开位置。第一流量控制通道连接入口通道和第二室，通道中的第一流量控制孔限制流动。感测隔膜将第二腔分隔成第三和第四腔。第二流量控制通道连接第二和第三室，通道中的第二流量控制孔限制流动。感测隔膜可以在防止流过第二通道的关闭位置和允许这种流动的打开位置之间移动。排气通道排出第三个室。感测通道连接出口通道和第四室。吸入插管将感测膜片移动到其打开位置以排出第二和第三腔室，导致主隔膜移动到其打开位置以将氧气输送到套管。

摘要： Layered, fiber-reinforced composites toughened by the use of thermosetting matrix resins including rigid particles are improved in toughness when the particles are porous and have a spheroidal spongy structure, are formed of a polyamide. The method of the invention is particularly effective in improving the toughness of composites based on thermoset matrix resins, and particularly epoxy resins.

摘要： A connector set adapted for releasably connecting a gas conduit from a gas appliance or the like to a gas line to provide gas to the appliance. The connector set comprises a nipple adapted to be connected to the gas conduit and a receptacle adapted to be connected to the gas line. The receptacle has a socket adapted to receive the nipple, and first and second valves. The valves are each operable between an open position and a closed position and arranged so that gas can pass from the gas line to the socket only when both valves are in their open positions. The receptacle further includes a mechanism for operating the second valve as the first valve is operated so that the second valve opens when the first valve opens and closes when the first valve closes. The first valve is operable only when the nipple is in the socket, and the nipple is removable from the socket only when the first valve is in its closed position.
摘要翻译：适于将气体管道从燃气器具等可释放地连接到气体管线以向器具提供气体的连接器组件。连接器组包括适于连接到气体导管的接头和适于连接到气体管线的插座。插座具有适于容纳接头的插座以及第一和第二阀。这些阀各自在打开位置和关闭位置之间可操作，并且被布置成使得仅当两个阀处于其打开位置时气体才能从气体管线传递到插座。所述容器还包括用于在第一阀被操作时操作第二阀的机构，使得当第一阀关闭时第一阀打开和关闭时第二阀打开。第一个阀只有在乳头处于插座中时才可操作，只有当第一个阀处于关闭位置时，乳头才能从插座中取出。

摘要： The adhesion of HMX crystals to the binder of a propellant material is sificantly improved by providing a polymeric polyurethane coating. The HMX crystals are tumbled in benzene to which is added a dilute solution of poly-aryl phenylisocyanate in methylene chloride, water and triethylamine. A secondary coating then may be applied by reacting residual isocyanates with ethanol.
