Before the start of the winding operation, the inner thread end (2) is guided via a thread-guide device (6) on the winding spindle (5) and is fixed. At the end of the winding operation, the outer thread end (3) is likewise inserted into the thread-guide device (6), and the two ends (2,3) are retained and drawn into the interior of the clew (1). At the rear end (14) of the clew (1), the inner threa...

A centrifuge adapter is formed in two sections divided by a plane that preferably extends through the longitudinal axis of the adapter. The two sections may be substantially identical in a first embodiment, each including a generally semicylindrical portion having a trough therein and further including an end portion. In a second embodiment, the adapter may comprise a first section including the e...

The cylinder gap between a punching cylinder, having a punching pattern, and a counter-pressure cylinder, which are provided for severing some of the layers of a multi-layered web, can be adapted stepwise, within the tolerance of the worked layers, to the actual layer thickness if the cylinders roll against one another with running rings arranged at the longitudinal ends, and if a plurality of ste...

Fibrous polyolefin nonwoven sheets are bonded and stretched in a continuous, multiple stage process. First, the sheet is heated without significant stretching to a temperature that is close to, but below, the melting temperature of the polyolefin. Then, as the sheet is forwarded to a first stretching stage, the sheet temperature is decreased by 5 DEG to 40 DEG C. and thereafter the sheet is alte...

A vehicle control and guidance system in which a desired route for the vehicle is stored in the vehicle in the form of co-ordinates in a ground reference frame. The "vectors" between these junction points are divided by successive reference points into incremental vectors, the reference points being generated ahead of the vehicle at regular intervals. A dead reckoning system predicts the position ...

The invention relates to a continuous sweetening process in the liquid phase for hydrocarbon charges containing sulphur-containing products. It is characterised by contacting a catalytic aqueous/alcoholic solution, which contains an organometallic chelate, an alkaline compound and an oxidising agent, and the charge in a lined reaction zone. The aqueous/alcoholic alkaline phase is separated off and...

PURPOSE:To improve productivity by using a fine pore-contg. polyester film having an apparent density and hiding degree of specific values as a substrate and forming a magnetic layer on one face. CONSTITUTION:The polyester film contg. the fine pores on the surface and in the inside is used. The apparent density of the film is specified to >=0.4g/cm<3> and <=1.3g/cm<3> and the hiding degree thereof...
