摘要： Apparatus is disclosed for providing increased heat transfer efficiency in a heat exchanger by separating contiguous fluid conductive channels by means of a flexible partition of a bimorph construction consisting of two adjacent layers of piezoelectric material arranged so that, when an electrical signal is applied, one layer expands while the other contracts causing the composite sheet to flex and push a sub-laminar layer of the fluid located adjacent to the sheet away into the turbulent stream while drawing other fluid into contact with the partition. The preferred embodiment of the invention additionally includes a grid or mesh member between the two layers for strengthening the partition so that it can withstand a relatively large pressure gradient thereacross.

摘要： An optical fiber element of low density, low heat capacity, a large coefficient of thermal expansion, and a large Young's modulus varies in light transmissivity gradually between its ends from high transmissivity to opacity, whereby power modulated light transmitted through the fiber element is absorbed to cause a change in temperature of the fiber element and a resultant thermal expansion and contraction thereof. As a transducer in a telephone receiver, a light absorbing fiber element or group of such elements is coupled between the optical fiber waveguide in the receiver and a resiliently mounted acoustical diaphragm which is caused to respond over the audible range.

摘要： An optical memory having a light valve for each memory bit. Each bit is programmed in a WRITE mode to pass or inhibit optical energy emitted from a local source of illumination and thus store a binary value of "1" or "0". A short length of optical fiber guides light from the light valve in a READ mode to the core of a transmission fiber which acts as a series transmission line for an optical pulse sequence when each of a plurality of the light valves is illuminated by a respective optical source, e.g., a light emitting diode. An optical energy absorbing termination is located at one end of the series transmission fiber while an optical amplifier device is located at the opposite or output end and, where necessary in between, with the amplified pulse sequence from the transmission fiber being thereafter coupled to one or more individual optical receiver and transducer units which generate respective corresponding electrical utilization signals.

摘要： A sound producing diaphragm of low density, low heat capacity, a large coefficient of thermal expansion and a large Young's modulus is located adjacent the end of an optical fiber transmission line element which is adapted to propagate modulated light and transmit the light outwardly therefrom particularly from the end region thereof to the surface of the diaphragm. The diaphragm absorbs light transmitted from the end region of the fiber optical element which heats and cools in response to the light energy absorbed thereby to expand and contract and produce a sound field. As a transducer in a telephone receiver, the diaphragm is mounted in the earpiece with the end of the optical fiber transmission line located in close proximity thereto and having an enlarged end which includes an anti-reflective coating so that light propagated along the fiber is transmitted to the diaphragm and not reflected back down the fiber.

摘要： Disclosed is a method and means to increase or decrease, on demand, the drag exerted by a fluid on a boundary. The boundary comprises a surface portion of a structure enclosing a moving fluid or may comprise a portion of the outer surface of an object moving through the fluid. Drag is varied by means of a set of piezoelectric sensors and an accompanying set of piezoelectric driver elements arranged in close proximity to one another at the boundary and electrically interconnected so that the pressure exerted by the moving fluid is sensed by one or more sensors and converted to an electrical signal which is then transformed into an electrical drive signal which is applied to one or more driver elements to cause a flexing of the driver element(s) in a predetermined direction so that drag is either reduced by moving the driver(s) away from the fluid or increased by moving the driver(s) towards the fluid. In the case of turbulent flow, drag is decreased by decreasing the pressure gradient in the fluid; that is, the drivers are moved away from the fluid in regions of high pressure and toward the fluid in regions of low pressure. The drag is increased by reversing these motions.
摘要翻译：公开了一种根据需要增加或减少由流体在边界上施加的阻力的方法和手段。边界包括包围移动流体的结构的表面部分，或者可以包括移动通过流体的物体的外表面的一部分。通过一组压电传感器和一组压电驱动器元件在边界处彼此靠近地设置并电互连来改变拖动，使得由移动流体施加的压力由一个或多个传感器感测并被转换电信号，然后将其转换成电驱动信号，该电驱动信号被施加到一个或多个驱动元件，以使驱动元件沿预定方向弯曲，从而通过移动驱动器来减小阻力，远离流体或通过将驱动器移向流体而增加。在湍流的情况下，通过降低流体中的压力梯度来减小阻力; 也就是说，驱动器在高压区域中被移动离开流体并且朝向低压区域中的流体移动。通过扭转这些动作来增加阻力。
