Abstract: The disclosure provides a turbine blade. A turbine blade includes a shroud at a tip of the blade and an airfoil having a leading edge extending between the shroud and a root of the blade; a cutout portion extending at least along the leading edge of the airfoil nearest the shroud; an insert welded to the cutout portion at a weld region; and a weld-free region located between the insert and the cutout portion nearest the shroud.

Abstract: A vacuum cleaner (1) comprising a housing (2) in which a drawer-like compartment (8) can be removably positioned, said compartment comprising a dust chamber (7) for receiving a dust collector which can be arranged in a suction air flow path between a connecting piece (4) of a suction hose (5) or a suction tube and an intake opening (20) of a motor/ventilator unit (21). In order to improve one such vacuum cleaner (1) such that the dust collector (16) can be removed from the vacuum cleaner (1) in a simple, user-friendly manner, the motor/ventilator unit (21) is fixed in the housing and the dust collector (16) can be removed from the suction air flow path by pulling out the drawer-like compartment (8). In this way, the drawer-like compartment (8) can be removed with little expenditure of force.

Abstract: A nonskid device for the wheels of vehicles, has a holding element (1) situated in the region of the wheel axis and used with elastic holding arms (2) holding a chain mesh (4). A tension cable (7) is used to introduce tension forces into the holding arms (2). In order to introduce a defined tensile stress into the tension cable (7), the tension cable is connected to a pivotable tension lever (12).

Abstract: The invention relates to a method and to a device for supporting a crystal ingot while pulling a single crystal, in particular such a crystal composed of silicon, according to the Czochralski method. To this end, a crystal support is provided which engages with a specialized bead, which is formed on the neck of the single crystal ingot and which has the shape of a bicone, by means of bearings in a housing. A support of the crystal ingot is thus achieved which may be disengaged at any time, and which has no disruptive effects on crystal growth and which acts independently of the length of the grown crystal. The bearings are moved into the support position on the bicone by a central pulling element which can be independently displaced relative to a second pulling element.

Abstract: A coffee maker includes a housing body having a base and a filter region disposed above the base, an accommodating space for a coffee pot formed between the base and the filter region, and a screen fastened in a releasable manner on the housing body, in the filter region, through at least one retainer, the screen being disposed on the front side of the coffee maker. The base has a recess, the screen has at least one side surface guided laterally along the accommodating space, and the side surface is connected in a releasable manner to the housing body, in the region of the accommodating space, by in each case the at least one retainer.

Abstract: An anti-slipping device has a tread network of chains connected to an external mounting by terminal links (20) of segments of chains (4, 5) of the network, and the external mounting is configured as a disc (13) in its peripheral area. The terminal links (20) are hooked into retaining anchors (19) formed by sections of a wire (18) which is held in place in guide channels (17) on the outside of the disc (13).

Abstract: An anti-skid device has rotating chains which are connected to an inner and an outer fixing device. The outer fixing device is formed from a ring-shaped disc (10) and a retainer ring (11). The retainer ring is provided for the end of a tensioning chain (8) which serves to lock or tension the inner fixing device formed by a spring steel clip. The disc (10) and the retainer ring (11) are detachably connected to each other for enabling the rotating chains (3, 4, 5, 6, 7) of the anti-skid device to turn.

Abstract: A device for connecting two bodies, especially a quartz body and a metallic body, which assures with few and simply formed components a high sealing ability at high temperature differences and at very low pressures and makes possible an easy assembly and disassembly. The device for the vacuum-tight connecting of two bodies of different materials, each of which has an essentially tubular end section (20, 30) and in the connected state of which the tubular end section (30) of the first body surrounds at least partially the end section (20) of the second body, includes an intermediate conduit (13) for intermediate suction removal of gases and is formed between the tubular end sections (20, 30) of the bodies with two seals (100, 150) which seal off the intermediate conduit (130).

Abstract: In a device for handling heavy components of a crystal puller according to the Czochralski method, a supporting beam that can be pivoted about one vertical leg of a supporting frame and vertically adjusted includes holding claws for accommodating components or auxiliary devices. Profile rails, on which a carriage can be laterally displaced, are arranged perpendicular to the supporting beam. The carriage can be connected to a receptacle for gripping and holding the crystal.
