Patent AT-E160601-T1 (AT)

Abstract: In the production of paper pulp by the sulfite pulping process, the amount of sulfite cooking chemical consumed per ton of pulp produced is significantly lowered, a much lower K-No. can be achieved without screen plugging, the wash circulation temperature is lowered, and the digester (19) runs better, in the practice of the invention. According to the invention, the wood chips entrained in sulfite cooking liquor are fed into the top of a digester, and flow co-currently to a central portion (21) of the digester, at which portion waste liquor is extracted and passed to flash tanks (25). An effective amount of the sulfite cooking liquor (preferably about 5-20%) utilized for producing the pulp is introduced into the vessel in the wash circulation (36), adjacent the bottom of the digester, to flow countercurrently to the material moving downwardly in the vessel. The produced sulfite pulp is withdrawn (at 33) from the bottom of the digester. The invention is primarily applicable to acid or bisulfite pulping, but also can be utilized with alkaline or neutral sulfite pulping. In some circumstances the entire cooking flow can be countercurrent (e.g. 5% up to close to 100% of the sulfite cooking liquor flows countercurrently to the material). <IMAGE>

Abstract: The winding apparatus comprises an elevationally adjustable bearing arrangement for rotatably mounting and driving a winding core. Underneath the bearing arrangement, there is provided a conveyor-belt arrangement which is driven by partially training or wrapping around the winding core or, as the case may be, a product package wound up thereon. The conveyor-belt arrangement conveys printed products, which are to be wound up, to the winding core. Prior to winding up the printed products, a winding band is unwound from the winding core and wound onto a winding-band spool. For this purpose, the winding-band spool is connected by means of a slip friction coupling with respective rolls and thus with the conveyor-belt arrangement. During the winding-up of the winding band in conjunction with the printed products onto the winding core, the winding-band spool is braked. A detaching roller for detaching the free end of the winding band wound-up on the winding core as a winding-band supply is drivably coupled with the winding-band spool by means of an endless belt. The endless belt takes the free end of the winding band from the detaching roller to the winding-band spool.

Abstract: A level shifter (600) receives a variable input voltage (VNINI), such as a beam current representative voltage of a cathode ray tube in a television receiver, and produces an output voltage (VNIN) that changes when the input voltage changes, such that the output voltage (VNIN) is level shifted relative to the input voltage (VNINI). The output voltage (VNIN) is coupled to an input terminal (+) of an error amplifier (610) of a power supply voltage regulator. The level shifter (600) includes a current mirror arrangement responsive to the input voltage. A band gap type voltage source (699) determines the amount of level shifting that is produced by the level shifter (600).   <IMAGE>

Abstract: The bottle-shaped container is made in a coextrusion blow molding process and has a dimensionally stable outer container and an easily deformable inner bag which consist of different thermoplastic materials that cannot be welded to each other. The preform has a diameter greater than that of the bottle neck so that, when the blow mold is closed, the blow mold halves squeeze off excess material not only on the bottom, but also in the shoulder and neck area. Unwelded seams of the outer container are thereby formed in the shoulder and neck area. In the bottom area the outer container is closed by a weld seam which has been formed by displacing material, the weld seam of the inner bag being fixed in said area. After negative pressure has been applied to the inner bag, holes are formed in the upper area of the outer container for the purpose of a permanent pressure compensation. All openings in the outer container are covered by the pump housing. The container operates reliably in the upside-down position.
