Abstract: A device for pumping fluid such as paints, sealants, caulks, and polymers made of a rotor assembly and a pump body. The rotor assembly contains at least one laminar flow element arranged in such a manner as to conduct the fluid from inlet to outlet as the rotor spins. The rotor may vary its distance from the pump body. This arrangement provides a rotor with exceptional capacity to pump without damage to the fluid media and to measure the fluid rate at low or high rotational speed with viscosity that can vary. The device also may provide a spray nozzle or nozzles that produce a multiplicity of spray patterns.

Abstract: This disclosure is directed to exemplary embodiments of systems, methods, techniques, processes, products and product components that can facilitate users making improved absorbance or fluorescence measurements in the field of spectroscopy with reduced (minimal) sample waste, and increased throughput, particularly in the study of biological sciences. A method and device for photometric measurement of liquids. The method includes the steps of: The method includes the steps of; providing a pipette tip, the pipette tip being made of an optically clear body having an outer wall and an inner wall, the inner wall defining an inner space for receiving a liquid sample, the inner space providing a cross-sectional path length for light; positioning the pipette tip between a light source and a light collector; measuring light transmission through the liquid sample; adjusting the inner space of the pipette tip to change the cross-sectional length, and measuring light transmission through the liquid sample. This can be accomplished by moving the light source from a first position to at least a second position to provide a plurality of cross-sectional path lengths through the liquid sample or by moving the pipette tip from a first position to at least a second position to provide a plurality of cross-sectional path lengths through the liquid sample.

Abstract: The present invention relates to the field of correlating a fluid flow rate by strategically measuring a differential pressure of a fluid. Embodiments of the present invention build off a simple concept of applying an aerodynamic device into a flow stream in conjunction with a flow concentrator and measuring fluid pressure at two locations on the aerodynamic device. The flow meter has not moving parts other than used for making tuning adjustments in some embodiments. A central design approach with the present invention is that each component can be adjusted relative to the other. Unlike prior systems that utilize a necked-down region of a fluid passage, the current system increases fluid velocities around a centralized flow element with the aid of an aerodynamic flow horn. Head losses are minimized through this approach. Additionally, having adjustability between the components will allow one to tune the flow meter to a preferred head loss and preferred pressure differentials by allowing the flow element to concentrically translate within its respective flow horn.
Abstract translation: 本发明涉及通过策略地测量流体的压差来使流体流量相关的领域。 本发明的实施例构成了将空气动力装置应用于流动集流器并在气动装置上的两个位置处测量流体压力的简单概念。 在一些实施例中，流量计没有用于进行调谐调节的移动部件。 本发明的中央设计方法是可以相对于另一组件调整每个组件。 与使用流体通道的颈缩区域的现有系统不同，当前系统借助于空气动力流动喇叭在集中流量元件周围增加流体速度。 通过这种方法减少头部损失。 另外，在组件之间具有可调节性将允许通过允许流动元件在其各自的流动喇叭内同心平移来将流量计调节到优选的头部损失和优选的压力差。
