摘要： Devices, apparatus, systems, and methods for the quick installation of ceiling fan blades for ceiling fans. The invention uses a blade with three slots running in a linear direction from the mounting end of the blade, and three pre-attached fasteners upwardly projecting from the outer end of a blade arm. One of the fasteners is springably bendable with inwardly extending clip edge, another fastener that forms an upright post, and a third fastener having a top end with an outwardly extending lip edge. Another embodiment can include four slots per blade and four pre-attached upwardly protruding fasteners per blade arm. A novel method of installing each blade can include angling the blade to the mounting ends of the blade arm so that the outwardly extending lip edge catches on the third slot in from the mounting end of the blade. Next, the blade is laid down so that the other two slot openings pass over the other pre-attached fasteners while moving the mounting end of the blade toward the motor mounting end of the blade arm. This causes the springably bendable fastener to bend back and snapably spring back catching onto the first slot locking the blade to the blade arm.

摘要： A locking device including a hoop, the hoop curling up to form an axial mounting hole in the middle. An upper convex block, a lower convex block, a middle aperture, a left aperture, a right aperture, an upper convex ear, a lower convex ear, an upper guiding inclined plane, and a lower guiding inclined plane are disposed in the device. The upper convex block and the lower convex block move axially to narrow the middle aperture, the upper guiding inclined plane and the lower guiding inclined plane contact with each other to make the upper convex block and the lower convex block to move circumferentially to narrow both the left aperture and the right aperture and enable the hoop to tightly hold objects inside the axial mounting hole. The locking device has a simple structure, low cost, robust connecting structure, convenient and efficient assembly and disassembly processes.

摘要： To provide a can manufacturing pump impeller in which a stress of a base portion of a blade is prevented from increasing while improving the strength of a joint portion of a hub and a boss. In order to reinforce a joint portion of a hub and a boss, a plate is jointed to the inside of an impeller. In order not to overlap a base portion of a blade and the plate with each other on the hub, an opening portion is provided in the plate around the base portion of the blade on the hub. As a shape of the opening portion, a semicircular shape, a semielliptical shape, a rectangular shape, or a trapezoidal shape can be selected. Further, as a plate shape, a flat plate structure, a shell structure, or a curved structure can be selected.

摘要： Within gas turbine engines is necessary to provide nozzle guide vanes between stages of the engine. These vanes are presented in vane segments and it is desirable to prevent leakage to retain engine operation efficiency as well as to avoid hot gas impingement on inappropriate parts of the engine. By use of anti-rotation blocks twisting between the segments can be prevented and therefore the segments retained in alignment. However, thermal distortion may open a chordal seal provided to inhibit gas flow leakage. By provision of chordal bumps it is possible to prevent forward rocking which will inhibit gaps between the chordal seal and an engaging support ring surface. Furthermore the anti-rotation blocks will generally incorporate appropriate mating surfaces to engage the chordal bumps across two or more vane segments to facilitate retention of vane segment alignment while achieving adjustment for thermal distortion.

摘要翻译： 在燃气涡轮发动机内部需要在发动机的各级之间提供喷嘴导向叶片。 这些叶片呈现在叶片段中，并且期望防止泄漏以保持发动机的运行效率以及避免热气体冲击发动机的不合适的部件。 通过使用防转动块，可以防止在段之间扭转，因此段保持对准。 然而，热变形可以打开提供的弦状密封以抑制气体泄漏。 通过提供弦状凸起，可以防止向前摇摆，这将阻止弦音密封和接合支撑环表面之间的间隙。 此外，防旋转块通常将合并适当的配合表面以接合两个或多个叶片段上的弦状凸起，以便于保持叶片段对准，同时实现热变形的调节。
