In order to provide a rotating machine in which the temperature increase distribution inside the machine can be equalized, not only is a primary cooler installed in the primary ventilation passage that extends from the exhaust side of the fans and installed on the rotating axis to the suction side of the fans and via the core, but a secondary cooler is installed in the secondary ventilation passage that is branched from the primary ventilation passage, thus making it possible to further cool par...

A rotating machine such as a submersible pump which comprises a casing (1) and a rotor (2) which is rotatable relative to the casing (1). The casing defines an aperature adjacent to which the rotor is positioned such that an annular gap is formed around the aperture between a first surface defined by the rotor (2) and a second surface (9) defined by the casing (1). One or both of the first and second surfaces is provided with a surface structure which is operative to prevent the accumulation of ...

A new type of rotating shaft, is registered in succession with a stepped shaft, a bush, a bearing lock sleeve, a jacket and bearings, in which the bush is rigidly connected with a bearing lock sleeve through a dowel, the bearings are matching with the stepped shaft and bearing lock sleeves by the round keyways respectively, oil filler points are set up on the jacket, bearing lock sleeve and bush, an oil reserving space being surrounded by the stepped shaft, jacket, and the liner outside the bear...

Apparatus and methods for mounting of a cooling device coupled to a circuit board include use of a clip that is rotated to mate with and engage the cooling device. Rotation of the clip occurs during installation of the cooling device and slides slots in the clip into interconnection with respective protrusions of the cooling device extending through the circuit board to where the clip is disposed. In an assembled configuration, the clip biases the cooling device to a processing unit coupled to t...

A rotating passage feed system for admitting pressure means into two machine parts (hub part (2), shaft (3)) which rotate relative to one another about a common axis. Conduits (17) that convey the pressure means are located in the shaft (3) and are joined to pressure means connections (6) via tapped holes while a connecting part (5) in which ring channels (8) are provided is also joined thereto. A central sleeve (9) is joined to the connecting part (5) in a non-rotatable manner. The connecting p...

Apparatus 10 for a skateboard deck 14 connected to a skateboard carriage 22 by means of a rotative mechanism 24 positioned between the deck and carriage. The carriage 22 is comprised of a platform having the trucks and wheels 18 mounted thereunder with fasteners fixedly positioning a bearing insert 34 and carriage retaining ring 32 to the top side of the platform. The deck 14 has a friction ring 30 fixed to the underside with fasteners 28 passing through the deck and friction ring into the carri...

One embodiment of a mechanism may include a member having a first axis and a surface non-concentric with said first axis, a first gear rotatably mounted on said member at a second axis different from said first axis, and a device coupled to either of said member or said first gear to rotate said member when said first gear rotates about said second axis.

The rotating valve for high performance liquid chromatography (HPLC) has a stator with connections for the solvent reservoirs, pumps, chromatography columns etc. and a disc-shaped rotor with connecting grooves on the front face for selectively connecting different connections to one another. Said grooves are evenly distributed on two concentrical circles. The connecting grooves on the front face of the rotor are configured in the form of circular segments and are arranged in such a way that fife...

A rotating display, particularly for use as a point of purchase inducement to customers in a retail environment, includes a two-sided display panel with fluorescent printed indicia or graphics on at least one side which are illuminated by ultraviolet light. The panel is rotated about its central longitudinal axis at a rotational velocity of at least approximately 300 RPM. The spinning fluorescent indicia, when illuminated in this fashion, create the illusion of a solid through the persistence of...

A rotating display that includes a fixed frame, a rotating frame that is rotatably mounted to the fixed frame, and apparatus that rotatably moves the rotating frame relative to the fixed frame. The apparatus includes a pool that contains water, eight movable arms that receive associated ends of associated fixed arms and move radially along the associated fixed arms, four joining bars that fixedly join and extend radially along aligned associated pairs of moveable arms, eight weights that are aff...
