摘要:
An extracorporeal circuit support with a main liquid pump, the inlet of which can be connected to the blood circuit of a patient via at least one first liquid line and the outlet of which can be connected to the blood circuit via at least one second liquid line, an oxygenator for enriching the blood being conducted in the at least one second liquid line with oxygen, and a pump drive which drives the main liquid pump. The extracorporeal circuit support has, in addition to the main blood pump or main liquid pump and the oxygenator, the pump drive designed to be MR-conditional, i.e., MR-compliant under specific conditions, and is designed in the form of a gas expansion motor. The extracorporeal circuit support can be used as a heart-lung machine or as an ECMO device

A device for removing impurities from shredded plastic has a first and second cleaning disk with first and second cleaning surfaces, the cleaning surfaces are opposite each other and delimit a cleaning gap. A drive device rotates the cleaning disks, and shredded plastic is fed between the cleaning disks. The cleaning surfaces have a plurality of cleaning ribs extending between an inner and outer edge of the cleaning surfaces, wherein at least one flank of the cleaning ribs is angled or curved relative to the axial direction of the respective cleaning disk, and a plurality of cleaning bars running transversally to the direction of extension of the cleaning ribs are arranged between at least some cleaning ribs neighboring each other.

An illumination mean for the inspection of flat substrates is disclosed. The flat substrate includes an upper edge area, a lower edge area and a front area. The illumination means is formed as an annular segment and comprises an opening into which at least the edge area of the flat substrate extends. A plurality of light sources are arranged on an annular segment in a housing. Inside the housing, a reflective element is provided so that the light from the light sources does not impinge perpendicularly on the upper edge area, the lower edge area and the front area of the flat substrate.
摘要:
A device for controlling and regulating a DC voltage converter. The device may have one or more power output stages and a control unit with a signal ground line. The one or more power output stages and the control line have a mutual ground potential. A switch for electrically disconnecting the signal ground line is provided. The switch is opened, when the DC voltage converter is active and the switch is closed, when the DC voltage converter is inactive.

The invention relates to an arrangement for an organic pin-type light-emitting diode with an electrode and a counter-electrode and a stack with organic layers between the electrode and the counter-electrode, where the stack with the organic layers comprises an emission layer comprising a k (k=1, 2, 3, . . . ) organic matrix materials, a doped charge carrier transport layer, which is arranged between the electrode and the emission layer, a further doped charge carrier transport layer, which is arranged between the counter-electrode and the emission layer, and one block layer, which is arranged between one of the doped charge carrier transport layers and the emission layer. The organic layers of the stack are formed by means of n (n≦k+2) organic matrix materials, where the n organic matrix materials comprise the k organic matrix materials of the emission layer. The stack with the organic layers can also be executed in a block-layer-free manner, where then the emission layer and the doped charge carrier transport layer are formed from an organic matrix material. Furthermore, a method for manufacturing such arrangements is stated.
摘要:
A plate of wood material, wherein wood fibers or wood flakes and synthetic particles or fibers, respectively, are compressed to a plate by a heat compression process, a portion of the wood flakes or fibers is substituted by a milled or fibrillated agglomerate of mixed synthetics of waste material from waste removal and the particle size of wood flakes or fibers on one side and of the milled agglomerate on the other side, is approximately equal.

An apparatus is provided for introduction and/or removal of a substrate into and/or from a process chamber of a vacuum coating unit that includes a process region adjoined by a lock chamber separable from surrounding atmosphere and from the process region by vacuum-tight lock gates. The process region encompasses a process chamber and a transfer chamber for altering transport speed. A vacuum-tight gate on the inlet side of a lock system is opened, the substrate is transported into the lock system and the gate is closed. Pressure in the lock system is subsequently matched to pressure in a subsequent space. An outlet-side gate of the lock system is opened and the substrate is transported from the lock system. The lock system includes a lock chamber and the adjoining transfer chamber. A passage between the transfer chamber and lock chamber remains open during introduction or removal of the substrate.
摘要:
A method for the recycling of all types of waste plastic, in particular mixed plastic (MP), in which compactate, in particular agglomerate, is ground from flakes or other plastic parts in at least one refiner stage in the presence of water, from which fine particles are removed from the ground material emerging from the refiner stage with the process water, the remaining ground material is washed and/or mechanically dehydrated and dried or the dehydrated ground material is again ground in another refiner stage in the presence of water and then dehydrated and dried, wherein the grinding of the compactate is performed in at least one refiner stage using a disk refiner (toothed disk refiner), the disks of which have engaging teeth, which are arranged separated on concentric circles, wherein there is a hole between neighboring teeth of a circle and the holes of a circle are each big enough that the particles to be ground or ground up to that point can pass through freely.
