A self flushing centrifugal pump has a fluid flushing passageway disposed in a housing of the pump which directs flushing fluid flow from a volute passageway in the housing of the pump near an outlet port of the pump to a chamber in the pump near a pump shaft seal and from the chamber to an inlet port of the pump via apertures in the impeller of the pump in response to rotation of the impeller.

An apparatus for the manufacture of wrinkle-resistant garments is disclosed which includes a housing enclosing a drum which is rotatable on a generally horizontal axis, whereby when the drum is rotated with garments disposed therein a tunnel defined by the garments is formed. Mounted on a door secured to the housing is an atomizer unit positioned to discharge a durable press resin in the form of a mist through a hole in the door and into the garment tunnel when the door is closed. In practice, d…

An adjusting drive for a transmission of a motorized vehicle has a housing and an adjusting member supported within the housing. The adjusting member has at least three control positions. The housing has at least two valve-controlled connecting adapters for supplying a pressure medium to the housing and loading the adjusting member on two sides. A gear shifting shaft is coupled to the adjusting member.

A turbomachine assembly includes a number of circumferentially spaced rotor blades, a number V of circumferentially spaced guide vanes axially adjacent to the rotor blades, an annular chamber surrounding the rotor blades, and an intake and exhaust for receiving and discharging air that passes through the annular chamber. When the turbomachine is in operation, spinning mode tones are generated by the interaction of the rotor and guide vanes. These tones are minimized by selecting a number of vane…

A low profile joint is provided for a strut tube extending radially through a strut extending between an outer casing and an inner hub in a gas turbine engine frame. The strut tube has a longitudinal axis and a closed distal end. A sideseat is spaced from the distal end and is disposed substantially perpendicularly to the longitudinal axis to define a flow orifice. A secondary tube has a ballnose at a distal end thereof disposed in abutting contact with the sideseat for channeling fluid therebet…

A stator vane assembly for a gas turbine engine that includes a plurality of circumferentially spaced ceramic vanes, each of which has an inner and outer ceramic shroud, and a ceramic post extending from one of the shrouds, and a metallic platform having a plurality of circumferentially spaced sleeves. A tolerance ring is mounted in each of the sleeves and then the ceramic posts are pressed into the rings. The assembly is then ready to be mounted within the engine. A method for assembling these …

A position indicating valve wheel (1) having a digit ring (28) in rotating communication with an intermediate wheel (35), both of which are rotatably mounted in a wheel house (1). A driver (51) secured to a flange (48) of a decimal ring (40) which is also rotatably mounted in the wheel house (1). The driver (51) being engageable with the intermediate wheel (35) once every full rotation of the wheel house (1). A resilient collar (49) extending from the flange (48) and engageable with the wheel ho…

A centrifugal pump is of the type having a diffuser (1) with upstream and downstream ends (1a, 1b), a delivery body (3) fixed to the downstream end and including a delivery chamber, a suction body (2) fixed to an upstream ends (1a) of said diffuser (1) and including a suction chamber. A jacket (8) is fixed between the suction body and said delivery body, defining a space within. The pump includes a multi-functional chamber communicating with said jacket, a first auxiliary outlet communicating be…

An axially compact axial flow fan with improved air-moving properties has a first array of fan blades that extend radially from a fan hub to a circumferential blade support member, a second array of fan blades extend from the first support member to a radially outward second circumferential blade support member. The fan blades in the second array each enjoy pitch angles that decrease from the second circumferential blade support radially along only a portion of each blade length. Thereafter, the…

A repair kit for replacing an unserviceable vane assembly in a turbine engine includes a serviceable vane subassembly 120 having a serviceable airfoil 124 with a base 134 attached to the root end thereof and an opposing base 156 which is unattached to but slidably engagable with the serviceable airfoil. The opposing base is slipped over the tip end of the airfoil and slid toward the opposing base. The vane subassembly and opposing base are pivoted into position between inner and outer engine cas…
