Abstract: Oxygen breathing masks, as well as methods of providing oxygen to persons, are detailed. The devices may include mechanisms for supplying either oxygen or ambient air to a person depending on inspiration pressure applied by the person to a first volume to which the person's mouth and/or nose is connected.

Abstract: The invention relates to an arrangement of a plurality of oxygen breathing devices, in particular for providing oxygen to passenger or crew of an aircraft, each oxygen breathing device comprising an oxygen source, wherein oxygen is stored, in particular in chemically bound form or compressed form, an oxygen guiding device for guiding oxygen from the oxygen source to a person. According to the invention, an arrangement of a plurality of oxygen breathing devices is provided, wherein a first one of said plurality of oxygen breathing devices further comprises an integrated transmitter comprising a sender adapted for wireless communication with a receiver of a second one of said oxygen breathing devices and a receiver adapted for wireless communication with a sender of said second oxygen breathing device.

Abstract: The invention relates to a light emitting diode (LED) which is electrically connected to an anode and a source. According to the invention one of the anode and the source is thermally coupled to a first heat conductor, the heat conductor being thermally coupled to a first Peltier element to convert thermal energy transmitted from and generated in the light emitting crystal when the light emitting crystal is provided with electrical energy into electrical energy.

Abstract: The invention relates to an oxygen breathing device for an aircraft, in particular for oxygen supply to crew member in a cockpit of an aircraft, comprising a filter unit having an inflow port and an outflow port, the filter unit being adapted to extract nitrogen from an air flow flowing from the inflow port to the outflow port through the filter unit, wherein the filter unit is adapted to receive compressed air, preferably, bleed air from a precompressor stage of a turbine driving the aircraft, or directly by a separate electrically driven compressor, via a bleed air supply line connected to the inflow port, a first pressure regulator in the bleed air supply line, a first water separator which is arranged in the bleed air supply line in flow direction of the bleed air before the first pressure regulator and a connection port which can be brought in fluid communication with said outflow port of the filter unit and which is adapted to be coupled to at least one oxygen supply mask via an oxygen supply line.

Abstract: Stowage systems having boxes with covers are addressed. Exemplary systems include mechanisms for biasing covers toward their closed positions and for blocking, or maintaining, covers in their open positions when necessary or desired. Such systems are particularly (although not exclusively) useful for cockpit storage of oxygen masks, where open covers might impede use of certain flight controls during aircraft operation but facilitate removal or reinsertion of the masks by a mechanic when the aircraft is not operating.

Abstract: This invention concerns a machine for working metals using an electron beam, characterized in that the gun and the enclosures occupy a fixed position in relation to one another, the gun being connected to each of the enclosures through a duct provided with a sealing valve a stage for electromagnetic deflection of the beam being provided between the gun and the ducts so as to deflect the beam successively towards the enclosures through the ducts.

Abstract: Machine for friction welding two parts comprising a first non-rotatable means for clamping the first of the two parts and a second rotatable means for clamping the second part. The machine is characterized in that the first non-rotatable clamping means is movable along the axis of rotation of the second means and in that the second rotatable clamping means is made up of a motorized mandril and a headstock clamping between them the second part, this headstock being movable along the axis of rotation and being provided with means for the support of the two pieces co-axially.

Abstract: A liquid scintillation spectrometer comprises two PM detectors, a circuit for detecting prompt coincidences between the signals from the detectors and a circuit for detecting delayed coincidences. Counting means controlled by the coincidence circuits detect the excess of the occurrences of prompt coincidences over delayed coincidences and count that excess in real time.

Abstract: A method of liquid scintillation counting utilizing a combustion step to overcome quenching effects comprises novel features of automatic sequential introduction of samples into a combustion zone and automatic sequential collection and delivery of combustion products into a counting zone.

Abstract: A sample radioactivity measuring system has a conveyor for moving a plurality of sample receiving locations in succession to a working position. A device for selecting the measuring program to be executed on the samples comprises a plurality of marker plugs each adapted to be removably located in the conveyor for movement by the conveyor. Each marker is provided with a different address code. Each address code corresponds to a location in a card reader. Cards insertable into the addressed locations each carry one of the programs and the program read from the card at the addressed location is used for processing the associated samples.

Abstract: A sample conveyor for a liquid scintillation spectrometer or gamma counting system comprises a plurality of cassette carriers and a mechanism for moving the carriers step by step along a closed path which includes a transfer station. Each carrier has an open bottom and may receive a cassette whose bottom wall consists of lips which may be opened by a mechanism when the corresponding location is at the transfer station.

Abstract: A device for measuring and dispensing fractions of a liquid sample comprises a casing having a vertical axis and containing a central chamber and transparent cells distributed around the chamber. Each cell is connected to the chamber by a closure cup. A capillary constriction separates each pocket from the corresponding cell. The device may be used for the preparation of antibiograms.
