摘要： Injection molded ring fan embodiments and methods for making them. The methods influence material flow during the injection molding process such that a major portion of the materials flowing in opposite directions in the outer rings preferably flow past one another, intermix in a swirling relationship, and/or collide at an angle relative to one another. This results in better material mixing or integration of the flow fronts. In one embodiment, the thickness of the outer ring varies in different portions between adjacent fan blades.

摘要： The invention relates to a method for the production of machine parts which are at least partially provided with a mineral casting. The mineral casting is carried out in a liquid state in at least one part of a housing element (1, 2) of the machine part acting as a casting mould, such that the mineral casting, after hardening, forms a lining element adapted to the inner contour of the housing element (1, 2). The aim of the invention is to enable the mineral cast lining elements (5) to be adapted as accurately as possible to the inner contour of the outer housing (1, 2) without any risk of destroying the mineral cast body (5) occurring when pumps are produced or operated. According to the invention, the inner surfaces of the housing element (1, 2) are treated with a separating means (3) prior to the casting out operation.

摘要： The present invention provides a miniature gas turbine engine for power generation. The engine has a highly integrated unitary rotor shaft where turbine, compressor and shaft are made in one piece in one fabrication process. The turbine and compressor are positioned back to back on the shaft in an overhung configuration, allowing the front bearings to be located in the cold zone of the engine. Preferably, the Mold SDM fabrication technique is utilized to make the unitary rotor shaft in one monolithic part out of ceramics such as silicon nitride, eliminating the need for post process assembly while strengthening the integrity, reliability, and performance of the unitary rotor shaft. Integrated with a permanent magnet in the unitary rotor shaft, the miniature gas turbine engine can generate electric power of 1 kW or less. Additionally, the axial length of the miniature gas turbine engine is about 100 mm or less. The miniature gas turbine engine according to the present invention is therefore particularly useful for powering lightweight, self-sustaining mobile devices such as unmanned vehicles and-autonomous robots.

摘要： Steam turbines with or without a control stage are constructed with the same number of control valves. There are preferably two control valves in each case. The valve subassembly, the turbine outer casing and parts of the turbine inner casing are of identical design and can be used for steam turbines with or without a control stage. In the case of the steam turbine illustrated with a control stage, the inner casing is provided with integrated nozzle boxes, which are separated from each other by intermediate walls. In the case of a steam turbine without a control stage, the nozzle boxes, and accordingly, also the intermediate walls are missing.

摘要： A bicast vane and shroud rings is provided in which thermal stresses are minimized. The vane has a flange portion along its inner and outer edge. These flange portions extend from the mid-chord of the vane part way towards the leading and trailing edges and follow the camber of the vane. Each of the flange portions has a width greater than that of the vane so has to form an overhang or lip about which conventional shroud rings are cast. As the flange portions approach the leading and trailing edges their width decreases and the overhang blends into the inner and outer edge to form rounded tops and bottoms at the leading and trailing edge. These rounded tops and bottoms reduce stress concentrations in the shroud rings and increase shroud material near these edges. Additionally, a stress relieving member is provided that embraces the top and bottom edges of the thin trailing edge, and inhibits the melting of the trailing edge during bicasting.

摘要翻译： 提供了一种双向叶片和护罩环，其中热应力最小化。 叶片沿其内边缘和外边缘具有凸缘部分。 这些凸缘部分从叶片的中间部分方向延伸到前缘和后缘并跟随叶片的弯度。 每个凸缘部分的宽度大于叶片的宽度，因此必须形成一个伸出或者唇缘，围绕这些突出部分或唇缘铸造常规的护罩环。 当凸缘部分接近前缘和后缘时，它们的宽度减小，并且突出部分共混到内边缘和外边缘中，以在前缘和后缘形成圆顶和底部。 这些圆形顶部和底部减少了护罩环中的应力集中，并增加了这些边缘附近的护罩材料。 另外，提供了一种应力消除构件，其包围薄后缘的顶部和底部边缘，并且在双打时抑制后缘的熔化。
