摘要： An adjustable pillow, comprising of a stretchable pillow cover having a plurality of removable inserts. The inserts may be in various thicknesses, shapes, compositions and firmness to permit adjustment for overall pillow height, overall firmness, and surface firmness when inserted into the cover. The total height of the pillow depends on the total height of the various inserts being used, the overall firmness depends on whether the inserts are soft, medium or firm, and the surface firmness depends on the firmness of the topmost inside layer.

摘要： Improved methods for treating metallurgical compositions involve reacting a metallurgical composition with an aqueous nitric acid solution. The reaction is performed at a pressure of at least about 220 psig and at a temperature of at least 100° C. The metallurgical composition comprises iron and one or more non-ferrous metals. The reaction dissolves the majority of the non-ferrous metal compositions into the solution which is in contact with solid ferric oxide. The reaction can be repeated on the isolated solids to increase the purity of ferric oxide in the solids. Zinc can be removed from the mixed metal solutions obtained from furnace dust by a variety of separation techniques.

摘要： A method and related ultrasonic meter identify and correct for transit time errors such as peak switch errors. The method includes calculating values for a set of diagnostics from measurements of the fluid flow, including transit time measurements. Based on the values for the diagnostics, and whether and how they fall outside of their respective ranges, the meter can identify a variety of problems with the meter or fluid flow, such as whether there has been an intermittent peak switch, a permanent peak switch, or the presence of noise, velocity pulsation in the fluid flow, temperature stratification, or other problem. In the event there is a problem with the meter, the meter self-tunes in order to minimize the chances of the problem happening again.
摘要翻译：一种方法和相关的超声波仪表识别和校正传输时间错误，如峰值开关错误。该方法包括通过流体流量的测量来计算一组诊断值，包括通过时间测量值。基于诊断值，以及它们是否以及如何超出其各自的范围，仪表可以识别仪表或流体流量的各种问题，例如是否存在间歇峰值开关，永久峰值开关，或噪声的存在，流体流动中的速度脉动，温度分层或其他问题。如果仪表出现问题，仪表会自动调整，以便最大限度地减少问题再次发生的机会。

摘要： A meter proving method and system. At lease some of the illustrative embodiments are methods comprising establishing a prover time by a prover device, measuring a flow rate of a fluid with a flow meter that uses multiple measurements taken over a period of time to produce each individual flow rate value (the flow meter electrically coupled to the prover device), and generating a meter volume over the prover time based on the flow rate. The generating the meter volume based on the flow rate does not involve: generating a pulse train output signal by the flow meter; and generating the meter volume based on an attribute of the pulse train.

摘要： An apparatus for measuring the time of flight of a signal is provided. The apparatus for measuring the time of flight of a signal comprises a transmitter for emitting a signal, a receiver for receiving the signal from the transmitter, and means for detecting the onset of the signal as it arrives at the receiver such that the period of time from emission by the transmitter to the time the receiver initially receives the signal can be determined. In another embodiment, the present invention provides a method for determining the time of flight of a signal comprising the steps of receiving a transmitted signal, operating on the received signal for generating a pre-conditioned signal, conditioning the pre-conditioned signal for removing irregularities therefrom for generating a conditioned signal, operating on the conditioned signal to form a discriminated signal, and determining the critical point of the discriminated signal such that the critical point can be used to determine the time of flight of the signal from the instant of transmission to the instant reception.
