摘要： A hafnium nitride coating is applied over the cubic boron nitride layer of conventional CBN tools by the process of arc physical-vapor-deposition at temperatures below the tempering temperature of the core metal. The hafnium nitride coating protects the cubic boron nitride or diamond abrasive and the core, resulting in a grinding tool with greater strength and longer life.

摘要： Systems and methods for mortgage portfolio evaluation are provided. Some embodiments of the present invention use a synthetic pool model as part of the process for evaluating and pricing mortgage servicing rights (MSR). In some embodiments, the synthetic pool model can identify a static pool of loans from the servicing portfolio (e.g., portfolio of residential mortgages) with collateral characteristics similar to the loans in the bid pool. Performance reports can then be created from the synthetic pool in order to estimate the performance of the loan servicer based on actual historical performance of a portfolio with similar characteristics. In addition, these reports can quantify performance assumptions for use in an MSR pricing model.

摘要： In a pulsed laser which is periodically energized so that it emits a pulse of radiation following each periodic energization, a feedback loop control system is provided for controlling energization of the laser so that the laser output radiation pulses are substantially constant over a relatively long period of operation, the feedback loop including a detector for detecting the laser pulses and producing an electrical signal representative of each pulse and a comparing circuit responsive to those electrical signals and a reference signal that represents the constant laser output level desired, for comparing the electric signals and the reference signals producing a control signal for controlling the energy of the periodic energization.

摘要： A design method for making a bituminous mixture that is used to form a vapor-permeable layer of pavement is provided. This design procedure includes preparing one or more bituminous mixture test specimens, measuring the performance of these specimens, and selecting a desirable bituminous mixture for paving that is vapor-permeable based on the performance of the specimens. Another aspect of the present invention is the selected bituminous mixture, which includes aggregate and a bituminous binder. The aggregate should be selected such that no more than about 5% by mass of the aggregate and preferably no more than about 3.5% by mass of the aggregate is able to pass through a 75 μm sieve. The selected bituminous mixture should have an Air Permeability Value that is at least about 8 cm2 so as to reduce its propensity for blistering during and after construction. Still further, the selected bituminous mixture should have desirable fatigue resistance and should be substantially water-impermeable.

摘要： A variable steam flow assembly for a steam iron includes a metering valve which does not depend on axial movement of a valve member with respect to a valve seat to control the steam flow rate, as in conventional metering valves, thus allowing the steam flow rate to be more accurately controlled. The metering valve includes a cylindrical gasket having a transverse bore disposed intermediate the ends. Longitudinal bores between each end of the gasket and the transverse bore define a plurality of flow passageways through the valve. A valving member is rotatably received in the transverse bore. Rotation of the valving member allows various flow passageways to be selected. The valving member is mechanically coupled to a steam flow control knob disposed on the exterior of the steam iron housing. The steam flow control knob is provided with a plurality of detent positions to allow a finite number of flow rates to be selected. A drip tube provided at the discharge of the metering valve prevents the valve member from being in direct communication with the steam generator. This reduces the possibility of mineral deposits forming on the valve member due to spattering resulting from the boiling of water droplets in the steam generator; hence changing the flow rate. The drip tube is provided with longitudinal bores of smaller diameter than the gasket that determine the flow rate through the valve.
摘要翻译：用于蒸汽熨斗的可变蒸汽流组件包括计量阀，其不依赖于阀构件相对于阀座的轴向运动，以控制蒸汽流量，如在常规计量阀中，因此允许蒸汽流量更准确地控制。计量阀包括具有设置在端部中间的横向孔的圆柱形垫圈。垫片的每个端部与横向孔之间的纵向孔形成多个通过该阀的流动通道。阀构件可旋转地容纳在横向孔中。阀构件的旋转允许选择各种流动通道。阀构件机械联接到设置在蒸汽熨斗外壳外部的蒸汽流量控制旋钮。蒸汽流量控制旋钮设置有多个制动位置，以允许选择有限数量的流速。设置在计量阀排出口的滴管防止阀构件与蒸汽发生器直接连通。这降低了由于蒸汽发生器中的水滴沸腾导致的飞溅而导致在阀构件上形成矿物沉积的可能性; 从而改变流量。滴管设置有直径小于密封垫的纵向孔，其确定通过阀的流速。
