A yarn delivery device according to the invention has a rotatably mounted shaft with a yarn delivery wheel which is mounted removably. A fastening element in the form of a nut or a screw, which are provided in each case with a handle, serves to fasten the yarn delivery wheel. As a result, the yarn delivery wheel can be exchanged by hand without the aid of a tool. As an alternative or in addition, the attachment of a tool is advantageously possible. A bearing face, which points in the axial direction, of an abutment preferably serves to adjust the yarn delivery wheel in a wobble-free manner. The radial orientation, the axial orientation and the wobble-free axial orientation are brought about by different functional faces, namely the flat face (30) and the cylindrical outer circumferential face of the shaft (7).

A flat screen assembly of the invention comprises a flat screen panel (P) and a stand device, where the stand device has a base means, a fixing means, a first support means and a second support means. The first support means comprises a support element, an outer washer (5) and an inner washer (6). In an assembled position, the fixing means is fixed to the base means, and the first support means is pivot-mounted to the fixing means, and the second support means is fixed to the first support means and to the flat screen panel (P). According to the invention a rotating partition (3) of the support element is pivot-mounted between the outer and inner washers (5, 6), which are fixed to the fixing means.

The inventive bearing system consists of a bearing seat (21), a roller bearing (18), and a squeezing element (26). The squeezing element lies flatly on the outer ring of the roller bearing and only in areas on corresponding areas of the bearing seat. The areas are preferably linear or strip-shaped and are oriented in an essentially axial manner. This facilitates the insertion and removal of the roller bearing (18) into or out of the bearing seat (21) and prevents the outer ring of the bearing from being rotated along, also in the case of bearing seats that are provided with relatively generous tolerances.

A thread delivery apparatus (1) for tension-regulated thread feeding has an adaptive regulator for controlling its drive motor (7). The adaptive regulator controls the drive motor (7) according to the thread tension which is detected by means of a thread tension sensor (12). A calibrating module (16) is provided for determining the compliance of the thread (2) in a test and for fixing the regulating parameters of the regulator correspondingly. This relates, in particular, to the D proportion of the regulator, but can also relate to the P proportion and/or the Ü proportion. The thread delivery apparatus is therefore adapted automatically to different use conditions.

A known flat screen assembly comprises a flat screen panel (1), e.g. a LCD panel (1), a housing with at least a rear cover (2) and a front cover (3) and with a connection means. The connection means comprises a connecting element (C) which, in an assembled position, is fixed to the flat screen panel (P) and to the rear cover (1). According to the invention, the connecting element (C) comprises at least one springy snapping portion. In the assembled position, the snapping portion (13) engages a corresponding snapping means of the front cover (2).

The disclosed embodiments relate to a system and method for mounting a light engine assembly. More specifically, there is provided a system (10) comprising a housing structure (11) including an upper portion (12) and a lower portion (14), a mounting structure (202) coupled to the housing structure (11), wherein the mounting structure (202) is not affixed to the lower portion (14), and a light engine (16) coupled to the mounting structure (202).

The invention relates to a device for sizing a fibre bundle (3), which comprises at least one sizing compartment (2) for contacting threads with a sizing bath (20, 25), said compartment being preceded by a feeding unit (1) and followed by a sizing material squeezing unit (27). The feeding unit (1) is designed as a multifunctional unit to operate both as a preliminary wetting means and as a wetting material squeezing unit (16) in order to perform preliminary wetting of the fibre bundle (3) with water (10, 14) or the like before it is introduced into the sizing bath (20, 25) and to perform squeezing of the threads after preliminary wetting but before sizing, without in principle using any additional unit.
