    Abstract: A pressure indicator (106) according to the present invention monitors the pressure of the fluid in a vessel (102). One embodiment of the present invention comprises a closed pressurized gas volume (210) behind a dimpled metal diaphragm (208). In normal operation, the force of the fluid pressure acting on the external surface of the diaphragm (208) to hold the diaphragm (208) in a concave geometry. In the event of a sufficient loss of fluid pressure, the force of the gas pressure acting on the internal surface of the diaphragm (208) will overcome the force of the fluid pressure acting on the external surface of the diaphragm (208), thereby moving the diaphragm (208) into a convex geometry. A viewing window (110) disposed in the side of the vessel (102) can be used to view the pressure indicator (106) and determine the shape of the indicator diaphragm (208).

    Abstract translation: 根据本发明的压力指示器（106）监测容器（102）中的流体的压力。 本发明的一个实施例包括在凹坑金属隔膜（208）后面的封闭的加压气体容积（210）。 在正常操作中，作用在隔膜（208）的外表面上的流体压力将隔膜（208）保持为凹形几何形状。 在流体压力的充分损失的情况下，作用在隔膜（208）的内表面上的气体压力的力将克服作用在隔膜（208）的外表面上的流体压力的力，从而移动 隔膜（208）变成凸起的几何形状。 设置在容器（102）侧面的观察窗（110）可用于观察压力指示器（106）并确定指示器隔膜（208）的形状。

    Abstract: A method of making a rotor yoke includes preparing a cured composite rotor yoke preform on a single-sided curing tool and machining at least one portion of the cured rotor yoke preform to form a rotor yoke. In one embodiment, preparing the cured composite rotor yoke is accomplished by applying successive layers of uncured polymeric composite material to a single-sided tool in a configuration to produce an uncured rotor yoke preform; disposing a semi-rigid caul to an untooled side of the uncured rotor yoke preform; enclosing the uncured rotor yoke preform and the semi-rigid caul by substantially hermetically sealing a vacuum bag to the tool; substantially evacuating a volume defined by the vacuum bag and the tool of air; and heating the uncured rotor yoke preform, sometimes under pressure, to form the cured composite rotor yoke preform.

    Abstract: A vibration isolator for connecting a first body and a second body. The vibration isolator includes a housing having a first chamber, a second chamber, and a port connecting the first chamber to the second chamber and permitting fluid to flow between the first chamber and the second chamber. The first and second chambers and the port defining a fluid reservoir. The isolator including a gas-to-fluid accumulator in fluid communication with the fluid reservoir through a first one-way valve and a second one-way valve. The first one-way valve allows fluid to pass only from the fluid reservoir to the accumulator and the second one-way valve allows fluid to pass only from the accumulator to the fluid reservoir. At least one of the first and second one-way valves being preloaded to a predetermined force to permit fluid flow through the at least one-way valve only when fluid pressure exceeds the predetermined force.

    Abstract: A vibration isolator (10) for isolating the vibration of two bodies that are connected together is disclosed. The vibration isolator (10) comprises an inner cylinder (16) and a pair of outer housings (12, 14) concentrically bonded together with elastomer structures (18, 20) to form two chambers (22, 26) that are joined by a tuning port (24). The elastomer structures (18, 20) may serve both as the seals for the chambers (22, 26) and the compliant spri ng members in the isolator (10). The isolator (10) connects to a vibrating body a spherical bearing (28). The chambers (22, 26) and tuning port (24) are fille d with an inviscid fluid (34) and pressurized to prevent cavitation. In certai n embodiments, pressure within the isolator (10) is maintained by a volume compensating device (30) connected to the chambers (22, 26) via a small diameter orifice (36).

    Abstract: A bearing assembly comprises a bearing, a shim disposed within the bearing, and a component disposed within the shim. The shim comprises a first material, the component comprises a second material, and the first material has an elastic modulus value that is lower than an elastic modulus value of the second material. An apparatus comprises an elastomeric bearing, a fiberglass shim, and a steel spindle that is connected to the elastomeric bearing through the shim. A method for reducing strain in an adhesive layer that connects a bearing to a component comprises selecting a shim material having an elastic modulus value that is less than an elastic modulus value of the component and providing instructions to connect the component to the shim by placing the adhesive layer between an outer surface of the component and an inner surface of the shim.
