Abstract: A network termination (NT) which is universally applicable and permits fair billing. The network termination (NT) according to the invention is characterized in that it comprises a switching facility (DET, 1, 2, 3) whereby the interface (a/b, U) on the network side is switchable from an analog one (a/b) to a digital one (U). A subscriber who needs a digital interface, for example because he wants to have two B channels of the ISDN at his free disposal, can release a digital interface (U) or have it released. A subscriber who wants only an analog access can release an analog access or have it released. To accomplish this, the network termination (NT) contains a switch (3) and a detector (DET). The switching between analog access and digital access on the network side can be effected without replacement of the network termination (NT).

A yarn lifter is positioned so as to lift the advancing yarn from contact with the outside periphery of the cooling tube over a partial length of the cooling tube, so that the cooling effect can be influenced without significantly changing the spiral looping on the cooling tube.

Abstract: An ink pump for a punp inking unit of a rotary printing press utilizes a two piece coupling between the ink pump and an ink pump drive unit. The ink pump is part of a replaceable inking unit while the ink pump drive unit is supported in the frame of the press. The two piece coupling operatively connects the ink pump and the ink pump drive unit. Each piece of the coupling is a permanent magnet. These engage in a non-positive fit to provide a robust coupling.

The matrix elements of the contact matrix (3through-passing channels (3a-3d) in which the conductors (10a-10d) have been placed and the ends of said conductors applied to the outlet ends (3oa-3od) of the channels. The conductor ends are each applied electrically to a contact receiving device through the medium of an electrically conductive and elastically resilient material.

Abstract: An apparatus and method for guiding and cutting a continuously advancing yarn (1) during a package doff in a takeup device. The yarn is guided by means of a yarn guide (18) which is movable substantially parallel to a package or to a new tube (13), which is driven by a drive roll (29). Downstream of the yarn guide (18), a deflection device (2) and a suction device (37) are arranged, with the suction device comprising a pneumatic vacuum connection (46) and a cutter (47). The suction device (37) cooperates with a transfer device (42) for purposes of cutting the yarn during a package doff and receiving the loose end of the advancing yarn. To enable a gentle processing of the yarn during the package doff, the yarn guide (18) is arranged in the path of the advancing yarn upstream of the driven tube (13), and a deflection device (2) as well as the suction device (37) are arranged downstream of the driven tube.

Abstract: The invention relates to a method for operating an occupant safety device and a control unit for performing the method. To limit the power supplied to a triggering means from a storage element, the electrical power supplied after operating each triggering means is measured and after a definable power limiting value has been reached the power supplied to the triggering means is interrupted. The known methods based on the voltage at the storage element being the measure of the power supplied prove to be highly prone to error because these depend firstly on the charged state of the storage element and secondly very much on the conductor resistance so that incorrect control action can result.

Abstract: A portable light reflector or diffusor includes a reflection or diffusion cloth attached to a foldable framework composed of longitudinal struts and a transverse strut which is stiff with respect to compression and connects the two longitudinal struts, wherein the transverse strut has ends bent in the direction towards the plane defined by the longitudinal struts and the reflection or diffusion cloth attached to the longitudinal struts, wherein the angle between the bent ends and the intermediate piece between the ends is greater than 90°. A belt extends parallel to the transverse strut in such a way that the longitudinal struts are pressed apart for tensioning the reflection or diffusion cloth.

Abstract: According to the invention, live images, in particular, from a CCD camera are compressed in two different ways in a monitoring instrument. On the one hand, compression is carried out at a low resolution, for example by means of H.261, H.263 or MPEG. On the other hand, compression is carried out at a high resolution, for example by means of JPEG, synchronously with the compression at the low resolution. A time code is generated for each image. The time code is, for example, a chronological code which contains the date and time of day. The time code can also be generated implicitly via a timer which runs simultaneously. Each image is stored twice, on the one hand as an image compressed at low resolution and, on the other hand, as an image compressed at high resolution. The time codes, which indicate links between corresponding images, are also stored.
