摘要： Disclosed herein are several embodiments of rotors (gears) which utilize spherical involute curves to determine the surfaces of the lobes (teeth). In some embodiments the contact surfaces are radial projections of spherical involute surfaces. In other embodiments the contact surfaces have a root and/or tip of a spherical involute curve, but are barreled or otherwise curved to reduce the point stress on each rotor. The rotors may also be configured where torque transfer is provided at a first set of lobes (teeth) and backlash removal is provided on teeth radially opposed to the first set of lobes (teeth). As the apparatus rotates, the position of torque transfer remains substantially the same, as does backlash prevention/removal, but the teeth providing these operations vary. The rotors may also be used for fluid flow.

摘要： The disclosed finger seals are designed to be operational under rotational velocity or a stationary condition. The contact surface of the finger seals is inclined in an axial direction. The rotational velocity of the bore does not affect the hydrodynamic lift and the finger seals can operate at any rotational speed, unlike prior finger seal where the hydrodynamic lift is generated by rotational velocity. Each finger seal is pressure balanced. The pressure chambers on the two sides of each finger seal are connected through the finger cutouts. The finger seal design is such that the fingers lift and move away from the bore surface in radial direction. In one form, each finger seal is designed with the specific required length to allow sufficient surface area for the hydrodynamic force such that the finger seals would be lifted from the bore surface at the design pressure.

摘要： This disclosure relates to a new multiphase pump with low recirculated volume. This device discloses novel inlet/outlet porting. One of the disclosed improvements is to port the inlet and outlet through the back of the rotors. In the model shown there is only one lobe on the first rotor, and two lobes on the second rotor. The double lobe rotor has the ports provided thru the back, in the lowest point on the buckets between the lobes. If there were more lobes on the two rotors, then the ports would normally be provided in the rotor with the higher number of lobes, preferably in the lowest point on each bucket. The single lobe rotor shown has voids formed in the outer circumference in order to balance the rotor—however, any rotor with more than one lobe may be naturally balanced and these holes may be unnecessary.

摘要： Disclosed herein is a valveless multitube pulse detonation engine including: a plurality of detonation tubes, wherein each detonation tube comprises an independent discharge outlet, and the plurality of detonation tubes interconnected at a common air/fuel mixture intake port. In the disclosed engine, an air and fuel mixture is detonated in the detonation tubes simultaneously, and the common air/fuel mixture intake port minimizes back-pressure caused by detonating the air/fuel mixture by directing multiple reverse shock waves into one another and effectively using the back-pressures as reacting surfaces for one another and effectively reducing the effect of back flowing shock waves moving towards upstream. The detonation tubes may be non-linear, and may have independent discharges. The independent discharges may be coupled to an adapter nozzle terminating in a combined exhaust outlet.

摘要： Disclosed herein is an efficient heat generation device where fuel is burnt in a pressure gain combustion process. The heat generating system has an inner combustion chamber that is housed in heat exchangers. The combustion chamber walls, in one form, include fluid conduits. While different fluids could be utilized, water is most common and the term water herein is intended to define water and all functional equivalents. The water conduits (tubes) may be multi-pass longitudinal, parallel to the combustor axis or they may be winded around the combustion chamber in a spiral fashion. The combustion products exiting the combustion chamber enter the outer liner where water tube bundles extract the heat of the combustion. One embodiment also utilizes an air preheating stage. Heated water and steam generated in the heat exchanger stages wrapped around the combustor enters the final heating stage where it passes through the flame accelerators in the combustion chamber. The flame accelerators within the combustion chamber are in the hottest region in the combustor and therefore exchanging heat at high temperatures increases the efficiency of the steam generation cycle. It also increases the produced steam quality.
摘要翻译： 这里公开了一种在压力增加燃烧过程中燃烧燃料的有效的发热装置。 发热系统具有容纳在热交换器中的内燃室。 一种形式的燃烧室壁包括流体导管。 尽管可以使用不同的流体，但水是最常见的，并且本文中术语“水”旨在定义水和所有功能等同物。 水管（管）可以是多通道纵向的，平行于燃烧器轴线，或者它们可以以螺旋方式缠绕在燃烧室周围。 离开燃烧室的燃烧产物进入外管，其中水管束提取燃烧的热量。 一个实施例还利用空气预热阶段。 在围绕燃烧器的热交换器阶段中产生的加热水和蒸汽进入最终加热阶段，在那里它通过燃烧室中的火焰促进器。 燃烧室内的火焰促进器处于燃烧器中最热的区域，因此在高温下交换热量可提高蒸汽产生循环的效率。 它也增加了生产的蒸汽质量。
