摘要： A quantum cryptography apparatus securely generates a key to be used for secure transmission between a sender and a receiver connected by an atmospheric transmission link. A first laser outputs a timing bright light pulse; other lasers output polarized optical data pulses after having been enabled by a random bit generator. Output optics transmit output light from the lasers that is received by receiving optics. A first beam splitter receives light from the receiving optics, where a received timing bright light pulse is directed to a delay circuit for establishing a timing window for receiving light from the lasers and where an optical data pulse from one of the lasers has a probability of being either transmitted by the beam splitter or reflected by the beam splitter. A first polarizer receives transmitted optical data pulses to output one data bit value and a second polarizer receives reflected optical data pulses to output a second data bit value. A computer receives pulses representing receipt of a timing bright timing pulse and the first and second data bit values, where receipt of the first and second data bit values is indexed by the bright timing pulse.

摘要： An apparatus for ultra-sonically cleaning any information bearing material, web, sheet, fiche, film or similar strip material is operable in two modes. The first mode is directed to cleaning the film, and employs a pair of air nozzles for nonevaporatively stripping cleaning solvent from the surface of the film, after the film has been immersed in the solvent. The action of the air nozzles creates a mist of solvent about the nozzles, which is condensed by a plurality of cooling coils and collected, and circulates same through a purification system and returns the solvent to the cleaning tank for subsequent reuse in the film cleaning mode of operation. The air emerging from the nozzles is returned to the air compressor, thereby forming a closed loop compressor system which minimizes escape of solvent vapors into the atmosphere. After a period of use in the film cleaning mode of operation, a second solvent reclaiming mode of operation drains the contaminated solvent from the cleaning tank, and circulates same through a purification system and returns the solvent to the cleaning tank for subsequent reuse in the film cleaning mode of operation. Both modes use the same cooling coils and purification system.

摘要： Apparatus and method for secure communication between an earth station and spacecraft. A laser outputs single pulses that are split into preceding bright pulses and delayed attenuated pulses, and polarized. A Pockels cell changes the polarization of the polarized delayed attenuated pulses according to a string of random numbers, a first polarization representing a "1," and a second polarization representing a "0." At the receiving station, a beamsplitter randomly directs the preceding bright pulses and the polarized delayed attenuated pulses onto longer and shorter paths, both terminating in a beamsplitter which directs the preceding bright pulses and a first portion of the polarized delayed attenuated pulses to a first detector, and a second portion of the polarized delayed attenuated pulses to a second detector to generate a key for secure communication between the earth station and the spacecraft.

摘要： A moisture stripping device for non-evaporatively stripping moisture from a moving film such as a photographic motion picture film. The film is cleaned in a liquid bath which has ultrasonic energy applied thereto. The film leaves the bath and passes through an air nozzle which is supplied with a source of air pressure. The air nozzle consists of a split block having a film slot extending through the block. A plurality of air jets are conducted into the slot at opposite sides thereof. The film, wet with cleaning solution, enters the slot and is non-evaporatively dried by air pressure which forms a moisture barrier at the lower edge of the slot. The slot is only slightly wider than the thickness of the film, yet the film is protected from touching the sides of the slot by an air cushion formed by air jets directed at both sides of the film. The air jets are formed by a plurality of air holes in the split block. The holes conduct air from the air source to the film slot. A relatively large pressure drop is provided across the air holes wth the result that a uniform pressure is developed across the entire face of the film, preventing it from contacting the surface of the split block. The slot has sharp edges at the lower side which receives film to maximize the moisture barrier effect.
摘要翻译：一种用于从移动薄膜（例如摄影电影胶片）中非蒸发地去除水分的湿气剥离装置。该膜在其中施加超声波能量的液体浴中进行清洗。该膜离开浴槽并通过一个空气喷嘴，该空气喷嘴供给一个气压源。空气喷嘴由具有延伸穿过该块的胶片狭缝的分割块组成。多个空气射流在其相对侧的狭槽中被引导。用清洁溶液湿润的薄膜进入狭槽，并且通过在槽的下边缘处形成防潮层的空气压力而非蒸发干燥。狭槽仅比膜的厚度略宽，但是通过由指向膜的两侧的空气喷射形成的气垫来保护膜免受接触槽的侧面的影响。空气射流由分割块中的多个气孔形成。这些孔将空气从空气源传导到胶片槽。在空气孔之间提供相对较大的压降，结果是在膜的整个表面上形成均匀的压力，防止其与分割块的表面接触。狭槽在下侧具有锋利的边缘，接收胶片以最大限度地发挥防潮效果。
