Title: Idler disk
Inventor: OKLEJAS ELI JR
IPC: F04D29/68
Filed: 1987-11-13
Abstract: An idler disk (45) for reducing fluid drag forces in a machine having a rotating component is disclosed. An outer housing (3) is provided for the machine and a cavity (5) is defined in the outer housing. The cavity (5) has opposed side walls. A rotatable component (13) is positioned in the cavity (5) and the rotatable component (13) is spaced apart from the side walls of the cavity (5). At least one freely rotatable idler disk (45) is positioned in the cavity (5) and the idler disk (45) is in spaced apart relationship with the rotatable component (13) and the side walls of the cavity (5). The idler disk (45) extends in the cavity (5) along at least at portion of the length of the rotatable component (13). The idler disk (45) is caused to rotate in the same direction as the rotatable component (13) by the rotating fluid in the cavity (5). The fluid is caused to rotate by the rotation of the rotatable component (13). An outer seal means (57) forms a seal between the idler disk (45) and the rotatable component (13). The outer seal means (57) is positioned adjacent the outer periphery of the rotatable component (13) and the idler disk (45). The outer seal means (57) acts to equalize the axial forces   on the sides of the idler disk (45) to maintain the idler disk (45) in a desired equilibrium position where the idler disk (45) is maintained in spaced apart relationship from the rotatable component (13) and the side walls of the cavity (5).

Abstract: A calorific value boiler device for supplying heat to at least one user of heat contained in a heat medium via a first supply line and at least one return line. The device includes a boiler having a blower equipped burner with flue gases discharged in a specific direction and at least two heat exchangers arranged in series to receive the flue gases sequentially in that direction. Also provided is a stratified thermal storage unit for delivering medium to the user via a first supply line. A first line is for transferring heat medium from the first heat exchanger in the series to the top layer of the storage unit. A second line is for transferring heat medium from the bottom layer of the storage unit to the last heat exchanger in the series. A third line is for transferring heat medium from the middle of the storage unit to the first heat exchanger and having a flow cross section at least twice that of the second line. A common pump is employed for transferring the heat medium through all of the heat exchangers, and the return lines return the heat medium to the mid level of the storage unit.

Abstract: A method and apparatus for improving the stripping of hydrocarbons from catalyst particles in a fluidized catalytic cracking (FCC) unit. A stripper vessel is located directly adjacent the exhaust barrel of a separator and immediately begins stripping hydrocarbon from catalyst particles. The stripper is sealed at the catalyst exit by a catalyst seal pot, with the drain sized to permit only a portion of catalyst flow to pass therethrough, with the remainder catalyst overflowing the seal pot. A short contact time stripper and catalyst particle deflector reduce the "residence" time of hydrocarbons with catalyst particles.

Abstract: In the corner joint of two frame members (1, 2) which are solid at least in the region of the joint, a strip-shaped projection (3) made on the one frame member engages in a matching groove (4) of the other frame member. Outside of this engagement, the mutually facing surfaces of the frame members butt against one another. The strip-shaped projection (3) and the groove (4) each have a recess (5, 6) running transversely with respect to the projection and parallel to the groove bottom. The two recesses complement one another in the engagement position to form a blind hole, which receives a cross-sectionally- matched blocking dowel (7). In one plane which is parallel to and at a distance from the strip-shaped projection (3), the two frame members are provided with corresponding bores (8, 9) in which a matching tenon (10) engages. <IMAGE>

Abstract: For convenient packaging of plastic bookbinding strips (21), cassettes are provided. The end edges of each strip are received in channels formed in opposed side rails (31). The rails engage adjacent either end the depending legs of transverse spacer bars. The spacer bars have plural sockets to engage projections on the upper ends of the legs so that the spacing between side rails may be varied to accommodate strips of different lengths - e.g., 8 1/2 inches, 11 inches, etc. Different length legs may be used to accommodate different length studs formed on the strips. By eliminating the legs entirely, flat female binding strips may be packaged in the cassette. A detent (67) is provided in the ends of the rails preventing removal of strips until the detent is bent out of position. The cassette is especially useful in equipment which mechanically assembles punched sheets and strips preparatory to binding a book in a binding machine.

Abstract: The invention relates to a device for the releasable connection of two parts. It has a receiving part (1) possessing a housing (3a). In the housing (3a) is mounted a bolt (5a) having an entry slope (7a). A closing pin (9d) with a displacement part (12a) serves for closing or for engagement with the bolt (5a) and is kept pressed into the closing position by a rubber ring (16). A release part (11a) is mounted slidably in the direction of movement (arrow 57) on the shank of the closing pin (9d). The closing pin (9d) carries a thrust plate (8) at its end facing away from the displacement part (12a). Insofar as pressure is exerted on this thrust plate, there first occurs the closing of the displacement part (12a) with the bolt (5a). When it is pressed further in the direction of movement (arrow 57), the release part (11a) forces the bolt (5a) away via the entry slope (7a) counter to the spring force of the rubber ring (16) and perpendicularly to the direction of movement (57). The bolt (5a) is then clamped on the displacement contour (17) of the release part (11a). It is thus possible to release the connection again by pulling the closing pin (9d) out of the receiving part (1). In another version, the bolt (5k;l) is held on the closing pin (9m;n) of the displacement part (12i;k) on the housing (3n;m). <IMAGE>
