Abstract: A measuring system for measuring direction related volumes, e.g. rooms in a building, is provided with an extractable measuring wire (12), the outer end of which can be moved to desired measuring points within the volume by means of a rod (20). A transducer (16) senses the length of the extracted wire, and two additional transducers (22, 26) sense the direction of the wire to the measuring point vertically and laterally. The output signals of the transducers are fed to a calculating circuit working the signals to a suitable form to achieve a dimensional drawing on a desired scale. For manual feeding of data related to the measuring point there is a portable keyboard unit (30) and in order to simplifying handling of the device the lower end of the rod (20) is attached to this unit (30). A gyro device (28) provides an outer reference so that measurements regarding different volumes can be related to each other. Thanks to the invention one person alone can perform accurate measurements without difficulty, e.g. of rooms in a building.

Abstract: The present invention comprises a method and apparatus for improving cooling of a wall in a gas turbine engine. The method and apparatus provide breach cooling of an imperforate wall, such as a combustor liner, for improving the cooling thereof. The breach cooling includes structure for channeling a cooling fluid as a jet toward an outer surface of the imperforate wall, with the jet having sufficient memontum to breach a boundary layer of the cooling fluid which forms over the wall outer surface to allow the jet to contact the wall outer surface for more effective cooling thereof. In an exemplary embodiment of the invention, the breach-cooled wall is an upstream portion of the gas turbine engine combustor, and the inner surface of the combustor liner facing the combustion gases is characterized by not having a film-cooling boundary layer of air to reduce quenching of the combustion gases for reducing exhaust emissions.

Abstract: The suspension ceiling grid system provides intersections including through-runners and oppositely extending runner ends. The through-runner is provided with a connector opening and the runner ends have identical end connectors. The end connectors are engaged and disengaged by lateral movement and provide spring which resiliently urge the end connectors toward the locked position. - The end connectors provide two locking systems, one of which provides a connection with the through-runner when only one connector is installed in the connector opening. It subsequently provides an improved strength functionally direct connection between the two end connectors when two end connectors are in stalled within the connector opening from opposite sides. The end connectors provide a second separate locking system which directly connects between the two end connectors.

Date Jul. 9, 1992.The present invention related to a drill bit (10) for rock drilling, preferably a down-the-hole drill bit, said drill bit (10) including a head (11) and a shaft (12), said head (11) defining a cutting face (14) that carries a number of hard material button inserts (15) having end portions extending outwardly of said cutting face (14), means (16,17) for transporting flushing medium from the free end (13) of the shaft (12) to the cutting face (14) of the head (11), said means for transporting flushing medium including a central passage (16) extending from the free end (13) of the shaft (12) and terminating in the head (11) short of the cutting face (14) and at least one branch passage (17) emanating from the central passage (16) and emerging in the cutting facc (14). In the field of down-the-hole drill bits big volumes of flushing medium, normally compressed air, are used since the flushing medium is also activating the down-the-hole hammer. Those big volumes provide erosion of the cutting face since the flushing medium has a very high speed when passing the front face of the drill bit. Said erosion creates problems when so much material, usually steel, of the cutting face had been eroded away that the button inserts are lost before they are worn out. The idea of the present invention is to decrease the velocity of the flushing medium before reaching the cutting face (14) of the drill bit (10). This is done by increasing the cross-sectional area of the branch passage (17) along a certain length (L) of said branch passage (17).
