Abstract: An air-conditioning system for an aircraft includes a compressed air branch for conveying externally supplied and pressurized air, preferably bleed air. Furthermore, a cooling circuit for conveying preferably liquid refrigerant is provided and extends through a ram air duct. The system also includes a first heat exchanger for the heat transfer between the compressed air branch and the cooling circuit, a compressed air turbine arranged in the compressed air branch and a cooling circuit compressor arranged in the cooling circuit and mechanically coupled to the compressed air turbine. The system can have a modular design and be positioned at optimal locations in the aircraft due to the separation of the compressed air branch and the cooling circuit. In this way, the length of hot compressed air ducts can be shortened.

Abstract: An inspection apparatus for examining vessels fixedly arranged on a machine tool. The apparatus includes a camera having a first optical component. The camera is coupled to an image processing unit and is arranged in a positionally fixed manner with respect to a vessel to be inspected. The apparatus has a second, moveably mounted optical element, with the first, positionally fixed optical element and the second, moveably mounted optical element being operatively connected to the camera for image-recording at least one view in the direction of a vessel opening and at least one view in the direction of a side of the vessel to be inspected that faces away from the vessel opening. A manufacturing system for vessels, which includes an inspection apparatus, and a corresponding examination method, which can be carried out using the inspection apparatus, for testing the vessel quality after machining is also disclosed.

Abstract: A method for galvanically depositing nickel, cobalt, nickel alloys or cobalt alloys in a galvanic bath includes using electrolytes containing nickel compounds or cobalt compounds. At least one anode and at least one cathode of the bath are subject to periodic current pulses. The IA/IC ratio of the anode current density IA to the cathode current density IC is selected to be greater than 1 and smaller than 1.5, where the anode current density IA and the cathode current density IC are defined as current densities with respect to a deposition body on which deposition occurs during the application of periodic current pulses where the deposition body serves as anode and cathode respectively. The charge ratio QA/QC=TAIA/TCIC of the charge QA, transported during anode pulse of duration TA, to the charge QC transported during a cathode pulse of duration TC, is between 30% and 45%.

Abstract: In order to allow current to pass a shaft bearing of a rail vehicle an additional rolling bearing is provided on the shaft and is electrically insulated relative to the shaft bearing. The inner ring of the additional rolling bearing is seated firmly on the shaft. A gap between the exterior of the outer ring of the additional bearing and the housing of the rolling mounting is provided with an insulating bush. The gap on insulating bush is bridged by an electrically insulated connector extending from outside the bearing housing and extending between the bearing housing and the outer ring of the additional rolling bearing.

Abstract: An axial anti-friction bearing for mounting of the spring pad in a shock absorber leg of a vehicle wheel. The bearing including two races supporting rolling bodies between them. Each race is supported by a separate annular plastic cap. The two caps are snapped together in a sliding manner with respect to each other by holding noses to form a structural unit. At least one pin and preferably a plurality thereof protrude approximately axially from the cap. The spring plate to which the bearing is supported includes cutouts, in the form of drain holes in the spring plate, placed to each receive one of the pins. The bearing is thereby held in snap like manner on the spring plate via the pins. Each pin is provided with a hook and each extends over an arcuate portion of the circumference of the spring plate, approximately 30.degree..

Abstract: A magnetic liquid sealing ring installed in an antifriction bearing between the outer and the inner rings is an integral structure comprised of a sealing ring, which is engaged in the bearing outer ring, and of a pre-seal at the axial inside of the sealing ring. Magnetic liquid elements are supported radially inward of the sealing ring by a magnet in the sealing ring. The pre-seal has an annular groove opening toward the bearing inner ring for holding escaping liquid. An axially outwardly facing shoulder formed on the bearing inner ring raceway cooperates with an axially inwardly facing inside of the pre-seal for defining a slot between them and those surfaces are inclined obliquely to the rolling elements and to the axis of the bearing.

Abstract: A high temperature reactor having a reactor core filled with spherical fuel elements is provided comprising a graphite side reflector including at least one nose-like projection protruding radially into the reactor core from said graphite said reflector, said at least one nose-like projection including a vertically disposed cavity adapted to receive discrete absorber material elements introduced into said reactor core as well as a vertically disposed continuous opening which permits communication between said cavity and the core of the reactor, and sealing means positioned in said continuous opening and cooperatively engaged with the portion of said nose-like projections defining said vertically disposed continuous opening, said sealing means being so configured and so cooperatively engaged so as to permit gaseous communication between said cavity and said core while preventing passage of said discrete absorber material elements through said continuous passage.

Abstract: An anti-friction bearing has a covering comprising first and second caps respectively over each of its races, and the caps are snap-locked to the bearing so as to enclose the bearing within it and to protect the same. An elastic material ring surrounds the peripheries of the two caps and protrudes outwardly protecting the bearing against impact damage. The periphery of the wall of one of the caps is conically tapered and the other of the caps pushes the elastic ring toward the wider end of the tapered wall for tensioning the ring.
