摘要:
A tool for attaching valve keys to a valve stem includes an elongated holder with a longitudinal axis, an inner hollow space and an end opening. An elongated core is arranged in the hollow space of the holder coaxially to the longitudinal axis. An elongated recess for receiving a substantial upper portion of the valve stem is provided in the end region of the core coaxially to the longitudinal axis. The recess of the core issues into the end opening and has a depth which is greater than or at least equal to the axial distance between the end and the annular groove of the valve stem. The core at least partially covers the annular groove, such that the valve keys can be supplied to the lateral surface of a valve stem underneath the annular groove and incorrect engagement can be avoided.

A complete passenger service unit (PSU) that includes a ducted housing that cools a stepped-down transformer from native 28 V DC aircraft power to 12-36 V DC to power and ultraviolet light producing ultraviolet wavelengths between about 200 nm and 235 nm. The ventilation air provided to all PSU stations is fed into the ducted housing to eliminate the need for additional fans or other cooling means for the transformer.

A method and an installation for high-pressure liquid jet deburring are proposed, in which a machined workpiece (44) is deburred by means of a high-pressure/high-speed liquid jet from a high-pressure jet nozzle (30) that is connected to a high-pressure liquid circuit (32). According to the invention, the deburring receptacle (16) has a flooding inlet (48) connected to a liquid supply circuit for flooding the deburring receptacle (16) with cleaning liquid and is configured to contain a bath (46) of cleaning liquid during operation. Prior to deburring, the deburring receptacle (16) is flooded with cleaning liquid via a flooding inlet (48) of the deburring receptacle. Further according to the invention, the machined portion (44) is deburred after flooding and by means of a liquid jet without gas sheath such that the high-pressure/high-speed liquid jet and at least the machined portion are immersed in a bath of cleaning liquid during deburring.

A motorized fishing reel device with a selectively actuated rotably mounted and motorized spool with a fishing line wound thereon. A mechanism for guiding the winding and unwinding of the line wound in a spool. The mechanism ensures that the line is properly wound when the spool is substantially coaxially aligned with the line in order to provide an ergonomically compatible handling of the device. A motor assembly with step-down and step-up gear assemblies that provide the rotational energy to the spool assembly and the reciprocating movement to a traveling pin with a line guiding roller at its distal end. A leg assembly that doubles as a storage compartment for back-up batteries is rotably mounted at one end to the housing assembly.
