Patent CA-2047025-A1 (CA)
Title: Liquid supply nozzle
Inventor: YANO HISASHI
IPC: B05B9/03
Filed: 1991-07-15
Abstract: ABSTRACT OF THE DISCLOSURE    A liquid supply nozzle is disclosed which is used for filling a container such as a tank with the liquid such as fuel.          The nozzle comprises a cylindrical nozzle body including a base end portion having an open end and a free end portion having a closed end, and a plurality of discharge openings formed in an upper area of the free end portion and through the wall of the nozzle body.  The liquid fed into the nozzle body from the base end portion is ejected via the discharge openings upwardly, i.e. in a direction opposite to a liquid level, and then drops onto the level due to a gravity.  A flow velocity when the liquid reaches the level is thus lowered as compared with an ejection directly toward the level, reducing a foaming on the level.  The plural discharge openings divide the liquid flow into streams having a smaller mass when ejected,  to further restrain the foaming.

Abstract: ABSTRACT OF THE DISCLOSURE In the arrangement for fastening a machine part on a foundation by using vertical anchor studs  (5),  a multiplicity of vertical anchor tubes (2) are cast into the  foundation  (1)  and  these  are connected to  one another, at least in groups, by means of an auxiliary frame  (8,  9,  10,  12;  28,  29, 30).   Provided at the lower end of each anchor tube (2), there is a ring (3) whose inner diameter is greater than the outer diameter of the anchor stud  (5)  and whose outer diameter is greater than or at least equal to the outer diameter of the anchor tube (2).  A space (6) with an essentially square outline is recessed in the foundation underneath this ring  (3).   Laid in this space with clearance, there is a threaded nut (4) with an essentially square external contour and a height smaller than the clear height of the space (6) mentioned, the lower end of the anchor stud  (5)  being able to be screwed into this threaded nut.     This design makes it possible to omit expensive templates when casting the foundation.   In addition, the subsequent horizontal alignment of the machine part or machine is possible without difficulty.                                           (Fig. 1)

Title: Labyrinth seals for gas turbine engine
Inventor: MARTIN JEFFREY C
IPC: F01D11/02
Filed: 1992-11-12
Abstract: Abstract of the Disclosure A labyrinth seal for a gas turbine engine of the type having a high pressure compressor and high pressure turbine, an outer shaft interconnecting the high pressure compressor and turbine, a low pressure compressor and turbine, and an inner shaft interconnecting the low pressure compressor and turbine wherein the shafts are concentric and are separated by the seal.  The labyrinth seal includes a cylindrical sleeve which is discrete from and attached to the outer shaft, and which includes a plurality of annular seal teeth extending radially-inwardly to the inner shaft. By placing the seal teeth on a sleeve which is discrete from the outer shaft and is easily replaceable, stress cracks created in the region of the seal teeth are prevented from propagating to the outer shaft and maintenance of the shafts is facilitated.  Further, by configuring the seal teeth to extend radially inwardly between two relatively rotating components, the fluid trapped by the seal is forced to take a tortuous path along the inner shaft; as a result, the seal of the present invention is more efficient at high temperatures and rotational speeds.  The sleeve is captured between an annular rabbet at an aft end and radial slots formed on a seal tube the latter of which engage spaced, axially-extending fingers on the sleeve at the forward end of the sleeve.  The sleeve is at a relatively low radius where mechanical deflections due to centrifugal loads of the two concentric shafts are similar.  Deflection of the seal teeth is away from the inner shaft due to thermal effects in the concentric shafts.
