Abstract: Described herein are a system for providing oxygen to oxygen masks in an aircraft, and an associated method for regulating the oxygen flow in an efficient manner. The system has an oxygen tank, oxygen masks, first and second oxygen lines, and an electrically controllable valve. The valve is coupled to the oxygen tank and the two oxygen lines. The oxygen masks are coupled to the oxygen lines downstream of the valve to accommodate the transfer of oxygen from the oxygen tank via the valve. In a working state when an electrical signal is applied the valve produces a connection between the oxygen tank and the first oxygen line when required, and permanently prevents a connection between the oxygen tank and the second oxygen line. When in a rest state, the valve produces a permanent connection between the oxygen tank and the second oxygen line.

Abstract: An oxygen supply device for an aircraft has a reaction tank for chemical oxygen generation and a pressurized tank filled with oxygen. The oxygen supply device also has an energy converter for converting thermal energy into electrical energy and also a control unit for setting a first amount of oxygen, provided by the reaction tank to a consumer unit, and a second amount of oxygen, provided by the pressurized tank to the consumer unit. The energy converter is designed to convert a thermal energy, generated by the chemical oxygen generation in the reaction tank, into electrical energy and to provide the electrical energy. The control unit is designed to set the second amount of oxygen, provided by the pressurized tank to the consumer unit, by using the electrical energy provided by the energy converter. The invention also relates to a method for supplying a passenger cabin of an aircraft with oxygen.

Abstract: A ventral bone-plate assembly has a U-shaped base having a pair of legs bridged by a bight and each formed with an inner hole and an outer hole. A brace bar extends between outer ends of the legs and is formed with end holes alignable with the outer holes. Respective inner bone screws extend through the inner holes, and respective outer bone screws each extend through a respective one of the outer holes and a respective one of the end holes.

Abstract: The present invention relates to nanoemulsions comprising alkyl and/or alkenyl ethers of alkyl and/or alkenyl (poly)glycosides, to a method for their preparation and also to their use. The present invention further relates to the alkyl and/or alkenyl ethers of alkyl and/or alkenyl (poly)glycosides themselves, and their use.

Abstract: A camera arrangement includes a camera having a lens pointed at a pane and being separated from the pane. A light-guiding element is between the camera lens and the pane. The light-guiding element guides at least light which is incident on the pane in a grazing manner from a direction of incidence to the camera.

Abstract: A camera arrangement for a motor vehicle includes a camera aimed onto a glass pane of a vehicle. The camera arrangement further includes a light-transmitting body having a solid and optically transparent material. The light-transmitting body is arranged between the camera and the glass pane and connects the camera to the glass pane. The light-guiding body may be an optically transparent, hardenable casting compound made of glass or a gel.

Abstract: An implant for insertion between vertebrae of the spinal column, as a substitute for disks, vertebrae, or parts of vertebrae removed from the spinal column. The implant has a first implant part and a second implant part, which are adjustable, relative to one another, in the direction of their coaxial longitudinal axes. The implant also has a joining plate that can be connected with the free end of at least one of the two implant parts, in an essentially perpendicular alignment relative to the longitudinal axis, by means for releasable attachment. This adjustability is to change the length of the implant.

Abstract: A spinal implant for engagement between a pair of vertebrae has a pair of parts displaceable relative to each other along an axis and each adapted to engage a respective one of the vertebrae. One of the parts is formed with a screwthread engaging a nut that bears axially on the other of the parts and that is formed with an externally accessible array of gear teeth. This implant is set by a setting tool having a holder fittable with the other part, a rotary member in the holder, and a gear on the rotary member meshable with the teeth of the one part when the holder is fitted to the other part.
