Abstract: A device is provided to fasten a susceptor of a CVD reactor to a drive shaft, and by the device, the susceptor can be set into rotation. The device includes one or more of a base plate, a support plate, adjusting levers, and a flange element. The drive shaft carries the base plate, to which the support plate, which carries the susceptor, is fastened. The inclination of the support plate relative to the base plate can be adjusted by the adjusting levers. The support plate is connected to the flange element by a screw. A through opening aligned with the screw is closed with a plug.

Abstract: In an embodiment a switching device includes at least one stationary contact, a movable contact, an armature, a first permanent magnet, a second permanent magnet and a magnetic switch, wherein the movable contact is movable by the armature, wherein the first permanent magnet is attached to the armature, and wherein the second permanent magnet is arranged in a fixed position relative to the magnetic switch.

Abstract: A luminous advertisement assembly includes a side wall, a transparent and/or translucent front plate and a profiled connecting element. The profiled connecting element has a first connecting region to which the front plate is fixed, and a second connecting region to which the side wall is fixed. The first connecting region is configured as a receptacle having a first leg and a second leg between which the front plate is received. A latching hook is disposed on the first leg and is configured to fix the front plate in the receptacle. A recess is disposed in the front plate, and the latching hook of the profiled connecting element engages in the recess of the front plate.

Abstract: A method for depositing a CdTe layer on a substrate in a vacuum chamber by means of physical gas phase deposition is provided. The substrate is heated to a coating temperature before the deposition process and then guided past a vessel in which CdTe is converted into a vapour state, a gaseous component with an increased pressure (compared to the vacuum in the vacuum chamber) flowing through at least one inlet, against the substrate surface to be coated, such that the gaseous component is adsorbed on the substrate surface to be coated before the substrate is guided past the at least one vessel.

Abstract: A method for producing a CdTe solar cell is provided, wherein at least the following layers are deposited on a glass substrate within a vacuum chamber: a TCO layer acting as a frontal contact; at least one CdTe layer; a thin layer of a chlorine-containing compound, and an electrically conductive layer acting as a return contact. Here, a maximally 20 nm thick passivation layer made from CdS, in which chemically non-bound oxygen is embedded, is deposited on the TCO layer prior to deposition of at least one CdTe-layer.

Abstract: An apparatus for generating a hollow cathode arc discharge plasma, including two plasma sources, each including a hollow cathode and an electrode which is associated with the hollow cathode and which has an opening that extends through the electrode, wherein the hollow cathodes of the two plasma sources are connected to a pulse generator which generates a bipolar, medium-frequency pulsed voltage between the two hollow cathodes. Here, in each of the two plasma sources, the hollow cathode is connected in an electrically conducting manner, directly or with interconnection of at least one current direction limiting component, to the associated electrode.

Abstract: The present invention describes a process for quenching a hydrothermal, dilute acid hydrolysis reaction of a biomass feedstock, wherein degradation of an aqueous monomer and/or oligomer sugar mixture is slowed down or stopped by flash cooling of the aqueous monomer and/or oligomer sugar mixture, and wherein the flash cooling ensures that a fraction of dissolved and volatile degradation byproducts are removed by a forming vapor stream, and wherein a lignin component, if present, is solidified into a structure with good de-watering characteristics, allowing for subsequent removal of the lignin component by separation, said process resulting in a hydrolyzed solution of sugar monomers and/or oligomers.

Abstract: The invention refers to a cartridge (1) adapted for insertion into a cartridge-seat that communicates with a low-pressure chamber, the cartridge by itself operating as a high-pressure chamber through the provision of a separate insert formed with a constriction that delays the flow of combustion gases into the low-pressure chamber. The insert is formed for insertion into the cartridge by the use of conventional reloading tools.

Abstract: A process and apparatus for plasma-activated electron beam vaporization is rovided. The vaporizing material from at least two vaporizer crucibles is vaporized with electron beams. An electric voltage is applied to the vaporizer crucibles in such a way that the vapor-emitting areas serve as electrodes of an electric discharge. The vaporizing material acts as a cathode or anode. The process and apparatus are preferably intended for the reactive coating of large surfaces and for the reactive coating of components, tools and strip steel.

Abstract: In a bullet trap for indoor shooting with small arms, which bullet trap, behind the targets, includes a vertically suspended curtain (1) made of rubber, and a vertically supported impact plate (3) made of steel and being spaced behind the curtain, the space between the curtain and the impact plate is enclosed by cover plates (4, 4', 5, 6) extending forwards from the side, upper and lower margins of the impact plate, covering the space between the impact plate and the curtain, whereby the latter is sealingly attached to the front edges of the cover plates through steel profiles (9), attached to the cover plates by screwing through the curtain. The enclosed space is continuously evacuated by connected fan means (10) and an interconnected filter (12) to prevent that lead containing dust, which is set free upon the impact of the bullets in the bullet trap, is distributed to the air and the shooting premises.
