Title: Sealing device for axial flow turbine
Inventor: KOMIYAMA MANABU
IPC: F16J15/16
Filed: 1999-03-05
Granted: 2003-08-19
Abstract: A sealing ring is formed by arranging a plurality of segments around the shaft of a rotor of an axial flow turbine with their outer parts received in a holding groove formed in an inner ring included in a nozzle diaphragm. Flat plate springs press the segments of the sealing ring radially inward, and curved plate springs press the segments of the sealing ring radially outward. The pressing forces of the flat plate springs and the curved plate springs are determined so as to compensate the differences in pressing forces acting on the segments of the sealing ring attributable to the respective own weights of the segments of the sealing ring. The flat plate springs and the curved plate springs prevent the irregular movement of the segments of the sealing ring, ensure the smooth radial movement of the segments of the sealing ring, and prevent contact between sealing fins attached to the segments of the sealing ring and the shaft of the rotor of the axial flow turbine.

Abstract: The invention relates to a bearing element having a base plate fitted on a support, for a seat or bed system, with a bearing plate to hold upholstery. The invention seeks to produce a bearing element whose range of spring is approximately equal to the total height, and which is easy to produce. To this end, at least two spring elements serving as bearing arms (12, 22) are fitted between the base plate (11, 21) and the bearing plate (15, 25). These spring elements, configured like leaf springs, are directed outwards from the base plate (11, 21). Their outer ends join the bearing plate (15, 25). In another version of the invention, a spring body (35, 35') is fitted between the base and bearing plate. The spring body head (35.2) and foot (35.1), like the bearing plate and base plate, have corresponding locking parts, so that the bearing plate can also be removably placed on the spring body (15, 15') and on the base plate (21). The invention also seeks to provide a bed system that is fitted with the inventive bearing elements, and which is characterized by its versatility. To this effect, fixing means for bearing elements are fitted on the plate or laths, preferably as undercrosses (30) that can be connected by socket connectors, with fixing means for the bearing element (10, 20) in the crossing area. A second version of the invention is intended in particular for lath frames (2) with mountable frame part(s) (3, 5, 7). In this version, at least one row of bearing elements (30') belonging to the outer mountable frame part is fitted with bearing elements (35') having a foot support (31) and a bearing plate (20, 40, 50). The other rows have bearing elements (30), which comprise a foot support (31), spring body (35, 35') and bearing plate (20, 40, 50).

Abstract: The present invention is a ladder rack providing for easier loading, unloading, and storage of a ladder. The ladder rack preferably has a pivot and a carriage mounted upon one or more arms attached to the pivot. A ladder is placed upon the carriage which can then be rotated via the pivot and arms (and preferably using a ratchet assembly) from a loading and unloading position to a stowage position separated by an obtuse angle. In some preferred vehicular applications, the unloading and loading position is beside the vehicle while the stowage position is over or above the vehicle. Also preferably, the carriage substantially overlies the ladder when in the stowage position, thereby providing for immediate and effective security against ladder theft as well as a compact ladder storage arrangement. Preferred embodiments of the present invention also employ a carriage that is slidable along the arms. This carriage has a rung grip which is separated a distance along the ladder rack from an opposed rung grip. When a ladder is mounted upon the rung grips, the grips are located adjacent respective rungs on the ladder. By sliding the carriage and ladder along the arms toward a retracted position, the distance between the rung grips shorten, thereby gripping and holding the ladder by compressing rungs of the ladder between the rung grips. One or more springs can be used to control movement of the pivot, carriage, and ladder, if desired.
