Abstract: A rail vehicle (10) with fuel consumers (20, 22, 30, 32, 34) and an on board fuel storage and supply system, characterized by a main fuel tank (24) adapted to be installed in a first railcar (12) of the rail vehicle (10), a buffer fuel tank (36) adapted to be installed in a second railcar (14) of the rail vehicle (10), and a fuelling device (38) for transferring fuel from the main fuel tank (24) to the buffer fuel tank (36). Preferred application to internal combustion engine rail vehicles with multiple railcars equipped with multiple diesel engines.

Abstract: An apparatus for determining an optimum sunscreen factor at any given time for the purpose of selecting a sunscreen suitable for protecting the skin, located in a housing is an indicator for the sunscreen factor, an energy source, preferably a battery, an on-off switch, as well as a sensor responsive to the tanness of the skin and provided with a pick-up which is connected via an electronic evaluation circuit with the indicator.

Abstract: A stuffing box which prevents the escape of highly pressurized, hot, solids-containing and/or toxic fluid media from the housing of a centrifugal pump has a receptacle with a flange which is sealingly secured to the housing and with a cylindrical portion spacedly surrounding that part of the pump shaft which extends from the housing. The receptacle contains a ring-shaped stop which is adjacent to the housing and surrounds the shaft, one or more deformable annular packings surrounding the shaft adjacent the stop, a reciprocable annular gland adjacent to the packings opposite the stop, and a sealing ring which engages the receptacle and the shaft and defines with the gland a plenum chamber for a sealing fluid. The pressure of sealing fluid exceeds the pressure of fluid medium in the pump housing, and the sealing fluid biases the gland against the packings so that the packings expand and sealingly engage the shaft and the internal surface of the cylindrical portion of the receptacle.
