摘要： An accumulator with an internal heat exchanger for use in an air conditioning or refrigeration system having a compressor, a condenser, an expansion device, and an evaporator is disclosed. In operation, the accumulator is placed in the system so high pressure, high temperature refrigerant flowing from the condenser and low pressure, low temperature refrigerant flowing from the evaporator simultaneously enter and flow through the heat exchanger disposed in the accumulator whereby the low pressure, low temperature refrigerant absorbs heat and thereby cools the high pressure, high temperature refrigerant. In one embodiment, the heat exchanger comprises a tube having at least one high temperature channel and one low temperature channel extending through the interior of the tube. In a second embodiment, the heat exchanger comprises a single spirally wound coaxial tube having an outer tube and an inner tube positioned within the outer tube. In a third embodiment, the heat exchanger comprises a plurality of coaxial tubes, each coaxial tube having an outer tube and an inner tube positioned in the outer tube wherein the inner tubes are fluidly connected.

摘要： A window sash balance shoe for use in a tiltable window assembly. The window sash balance shoe is capable of adjusting the frictional force between a window sash and the walls of a guide track sufficient to allow said window sash balance shoe to maintain its vertical position in the guide tracks along the range of vertical positions, but insufficient to prevent the window sash balance shoe from being raised or lowered. The window sash balance shoe has a body having a transverse bore within which a friction adjustment cam resides. As the friction adjust cam is rotated it causes the body to expand within the guide tracks. The window sash balance shoe additionally provides a connector for receiving a pivot bar of a window sash and a connector for receiving a tension device or spring. The connector for receiving a tension device is a hook having a notch formed in the convex side of the hook. The notch provides a point at which the end of the tension device can stretch over the hook and rest within the notch.

摘要翻译： 用于可倾斜窗组件的窗框平衡鞋。 窗框平衡鞋能够调节窗扇与导轨的壁之间的摩擦力，足以使所述窗框平衡鞋沿垂直位置的范围保持其在导轨中的垂直位置，但不足以 防止窗框平衡鞋升高或降低。 窗框平衡鞋具有具有横向孔的主体，摩擦调节凸轮位于该主体内。 当摩擦调节凸轮旋转时，使得主体在导轨内膨胀。 窗框平衡鞋另外提供用于接收窗框的枢轴的连接器和用于接收张紧装置或弹簧的连接器。 用于接收张紧装置的连接器是具有形成在钩的凸面中的凹口的钩。 切口提供了张紧装置的端部可以在钩上延伸并停留在凹口内的点。
