Abstract: Polymeric materials, particularly polyethylene (PE) are crosslinked by using a new continuous method based on photo-initiated crosslinking with UV-light. In the method of processing, the polymer, after mixing with suitable crosslinker, photo-initiator, and possible stabilizers, is extruded into a suitable shape whereupon the still warm, soft melt, directly after extrusion ("on line") is crosslinked to a high gel content. New photo-initiators with high solubility in the polymer melt and with low vapor pressure in the melting range of the polymer have been manufactured and are used in the process. The polymer melt is taken through an irradiation unit containing one or more UV-lamps. The method is fast and can be used for crosslinking of e g tape, hot water pipes and electric cable insulation.

Abstract: The one ends of two webs made of flexible material forming the door leaves of a laterally opening roller door are fastened to a vertical sealing profile designed as a closing edge. The other ends of the two door leaves are fastened to two vertical winding shafts which are arranged in the region of a vertical frame member of the door frame. The sealing profile is supported by a slide or carriage which is guided in a guide of the upper frame profile of the door frame. In order, in a simple and light construction, to make possible rapid opening and closing of the roller door, the winding shafts are acted upon by a torsion spring in the winding-up direction of rotation. Between the vertical frame member and the sealing profile, at least one stretching member is arranged, which acts on the sealing profile in the closing direction with a force tightening the door leaves. At least one winding shaft is driven by a geared brake motor.

Abstract: Apparatus for forcing a memory cell to a known state upon power-up includes circuitry for providing two signals PWRUP and PWRUPB which are used during chip power-up. At power-up, as V cc  rises from 0 volt to 3.5 volts, the PWRUP signal follows V cc  and the PWRUPB signal maintains 0 volts. The PWRUP and PWRUPB signals are used to drive the gates of P-Channel and N-Channel MOS transistors, respectively, including pass gates connected between word line driver circuits and bit line driver circuits driving the word lines and bit lines associated with the memory cells. In addition, the PWRUPB signal is used to drive P-Channel MOS pullup transistors connected between the word lines and V cc  and the bit lines and V cc . During power-up, the pass gates are disabled, disconnecting the word lines and bit lines from their drivers. The word lines and bit lines are forced to follow the rise of V cc  by the P-Channel pullup transistors. When V cc  reaches its desired value, the PWRUP signal goes to 0 volts and the PWRUPB signal goes to V cc , thus turning on the pass gates to connect the word line and bit line driver circuits to the word lines and bit lines. The V cc  final PWRUPB signal turns off the P-Channel MOS pullup transistors connected between the word lines and V cc  and the bit lines and Vcc.

Abstract: In known winding machines equipped with flyer-type traversing devices, the axes of the two rotors are inclined, so that the yarn run forms an acute angle  alpha  with the planes of rotation. There is a narrow clearance d between the planes of rotation of the two flyers. As a result of the inclination, therefore, the circle of rotation of the flyers of one rotor projects somewhat beyond the circle of rotation of the flyers of the other rotor in the traversing region. As a result, the flyer constellations and cycles of movement at the two stroke ends are not exactly identical. This brings about a differing bobbin build-up on the two end faces. The new device is to remedy this shortcoming. For this purpose, the axis of the rotor (14), the flyers (15, 16) of which rotate in the plane of rotation further away from the guide roller (2), is set back in the direction at right angles to the axis (2') of the guide roller (2) relative to the axis of the other rotor (8) by the amount  a = d.cot  alpha . This arrangement ensures that, exactly at the moment when the flyers have reached the angular position corresponding to the stroke end, the delivering flyer has dipped down behind the yarn running surface and the receiving flyer rises out of the yarn running surface. <IMAGE>

Abstract: Energy and data signals are intended to be transmitted simultaneously via a two-wire bus (1), to which bus subscribers (2) are connected. The current-carrying capacity is restricted on the basis of the voltage drop on the bus line. According to the invention, energy for the connected bus subscribers (2) is additionally fed in at a plurality of points along the two-wire bus (1) via coupling components (3). The coupling components (3) electrically isolate individual bus segments (20) from one another and simultaneously enable the transmission of data signals to all bus subscribers (2). Capacitors (4, 5), which transmit the data signals without obstruction but which present a barrier to DC current, are used for this purpose in the coupling components (3) along the line of the two-wire bus (1). Inductors (6, 7), which block the data signals but allow the DC current to pass through, are disposed in the connection lines of a DC voltage source (14). <IMAGE>
