Abstract: A centrifugal pump assembly includes a pump head, a pump base defining a pump inlet and a pump outlet, a fluid outlet channel from the pump head to the pump outlet, impellers, defining an impeller fluid channel between an impeller inlet and outlet and connected with one of rotor shaft segments including a positive fit coupling for torque transfer between at least two rotor shaft segments, and one or more pump stage housing segments arranged between the pump base and the pump head. The pump stage housing segments have a structure defining a guide passage for receiving pumped fluid from the impeller outlet of the impellers and for guiding pumped fluid to the impeller inlet of another one of the impellers or to the pump head. The pump stage housing segments each have a structure defining at least a part of a wall section of the fluid outlet channel.

Abstract: A communication system includes a headset, which is configured to output sound waves to an ear of a user based on an audio signal, as well as a microphone, which is configured to output a microphone signal based on ambient sound. The communication system further contains a processing circuit, which is configured to generate, based on the microphone signal, a signal component of the audio signal, which signal component includes information about the generation of sound waves which interfere destructively with a component of the ambient sound occurring at the ear of the user. In addition, the communication system contains a wireless interface and a control circuit, which is configured to activate the processing circuit as a function of an operating state of the wireless interface.

Abstract: A socket spanner insert releases or fastens wheel bolts which in the mounted state rest inside wheel bolt holes of a car rim. The socket spanner insert includes a base body which has a screw head receptacle and a tool receptacle, and a sleeve which encompasses the base body at least in portions and is rotatably connected to the base body. In order to prevent damage to the rims when mounting and removing wheel bolts, a retaining element is provided which, during release or fastening of the wheel bolt, blocks a relative rotational movement of the sleeve with respect to the car rim and allows a rotation of the base body within the sleeve.

Abstract: A process for the additive manufacture of a metallic and/or vitreous and/or ceramic component, a mixture of substrate particles and an at least two-phase binder is firstly provided. The mixture is preferably provided as composite particles, so that the substrate particles adhere to one another by the at least two-phase binder. The mixture is selectively melted layerwise by electromagnetic radiation so that a shaped part is additively produced. The shaped part is taken out from the mixture which has not been melted and the at least two-phase binder is subsequently removed, preferably successively. The process produces a microporous shaped part which after sintering leads to a component having a desired density and a desired mechanical and/or thermal stability.

Abstract: A device (1), for a ventilation system (100), includes an inhalation valve (10) with an inhalation opening (11) for flow (301) of breathing gas (300) into a pressure chamber (110) to provide breathing gas in the pressure chamber for ventilating a patient (200). A closing element (12) is arranged movably, to close the inhalation opening to flow in a closed position (320) and to at least partially release flow in an open position (310). A transmission device (13) is connected via a connection element (14) to the closing element, to hold the closing element in the closed position in a starting position of the transmission device, such that the inhalation valve is normally closed. A control pressure source (130) provides a control pressure (PS) in a control pressure chamber (15) for the transmission device to move the transmission device out of the starting position by the control pressure.

Abstract: A lighting unit (100) for a medical luminaire (150) has a number of groups of LEDs (110, 110′, 110″) that are connected to a common planar printed circuit board (115). Each LED (112, 112′) of at least one of the groups (110, 110′) is associated with a respective optic (122, 122′) by which a respective LED-optic pair (120, 120′) is formed. The respective optics, based on the structure (328), specify a tilt angle (125) of a central light beam axis (124, 124′) of an emitted light beam of the LED optics pair in a tilt direction (627) of the respective LED optics pair. The tilt direction is defined such that the respective light beam axes of the emitted light beams of the LED optics pairs from the at least one group of LEDs are at least partially skewed in pairs with respect to one another.

Abstract: A computer implemented method and a system abates the presence of sulphide (H2S(g), H2S(aq) or HS-(aq)) in a wastewater flowing in a specific wastewater network from an upstream pumping pit to a downstream pumping pit or manhole. The computer implemented method and a system includes dosing into the wastewater at a position upstream of the downstream pit or manhole a chemical for abatement of sulphide, determining by use of a sensor the concentration of sulphide at a position downstream of the position at which chemical is dosed into the wastewater, such as located in the downstream manhole. The amount of chemical dosed is determined by use of a general agent and a specific agent.
