    摘要: A circuit configuration for producing an output voltage having a first polarity with respect to a reference potential, in a mobile radio transceiver supplied with an operating voltage having a second polarity with respect to the reference potential, includes a circuit input terminal for a ringing signal generator supply voltage. A preferred embodiment operates according to a fundamental functional principle of charging a first capacitor to a positive voltage with respect to the fixed reference potential through the use of a voltage overshoot at a coil after the latter has been deenergized. During an on phase of a transistor, the first capacitor charges a second capacitor to a negative voltage with respect to the fixed reference potential. The negative voltage can be picked off externally.

    摘要: A clutch housing for a vehicle transmission assembly and a method of making the same. The housing is generally cup-shaped with an axial hub. The outer wall of the housing is formed with a plurality of longitudinal splines of varying configurations. Select splines are formed at an increased depth. A groove is formed in the exterior surface of the housing at a depth sufficient to intersect the select splines of the inner surface thereby forming apertures through the wall of the housing. The dimensions of the apertures are determined by the configuration of the exterior groove and the interior splines.

    摘要: A process and apparatus for the control of a yarn storage mechanism on a spinning mill machine is proposed. When yarns are wound up it may occur, e.g. in forming conical bobbins, that more yarn is delivered than is wound up. The yarn which is briefly in excess is here taken up in form of a yarn loop by a compensator arm which intervenes transversely in the course of the yarn and is mounted so as to be capable of swivelling. According to the invention it is proposed that the compensator arm be subjected to the force of a spring which acts upon it increasingly as the yarn loop decreases, and in that the force of an additional elastic element acts upon the compensator arm as further excursion occurs.

    摘要: An insulating supporting frame of a multi-pin switch arrangement has a box-shaped base part and an insulating supporting part arranged over it. Insulating housings encompassing the vacuum switch tubes are formed onto a wall part. On the rear, bearing parts which are parallel to one another and at a distance from one another are cast onto the wall part, the bearing parts being connected to a top wall of the box-shaped base part. A drive shaft of a spring-force drive is mounted on the bearing parts. The spring-force drive is connected via a linkage to a movable switch contact of the vacuum switch tube. The one-piece insulating supporting frame is constructed in such a way that practically all the parts of the switch arrangement can be arranged on it.

    摘要: The invention relates to a mold for the continuous casting of preliminary sections, in particular double T-shaped preliminary sections, such as beam blank sections or similar sections, wherein all the interior walls (7a to 7i) of the mold in the mold passage (8) have a tapered course (9 to 12) running linearly from top to bottom, said tapered course being dimensioned depending on the degree of shrinkage of the cast strand and produced by machining the interior walls (7a to 7i). In this manner, it is possible to optimally adjust the diameter of the mold to the shrinkage process of the cast strand in the region of the mold passage, even for large-sized sections.

    摘要: The invention relates to a method and a device for guiding and orienting a strand (5) in a continuous casting facility for large-sized round sections made of steel or a similar material. In order to prevent the formation of cracks while the strand is oriented, the outer surface (15) of the strand is heated from above and from below inside the orienting track. For this purpose, porous burners (10, 17) are arranged in the discharge section of the directing track, the hot gas emitted from said burners flowing entirely around the outer surface (15) of the strand.

    摘要: The invention relates to a method and a device for producing nitrogen fertilizer from organic waste products in the liquid phase (suspension, emulsion, solution) and for hygienizing the wastes or reducing the emissions by thermal treatment using mineral or organic additions.According to the invention, this is achieved by a method, wherein the waste product is heated at underpressure to temperatures between 40 and 90° C., the escaping gas containing carbon dioxide and ammonia is cooled down and introduced into an aqueous absorption agent, the nitrogen fertilizer formed thereby is discharged and the excess gas not having been absorbed and containing carbon dioxide is pumped back into the discharge container, wherein the underpressure generated at the beginning of the process by a vacuum pump is autogenously maintained by the progress of the process.Suitably, the return of the excess gas into the cycle is performed by either conducting it immediately above the waste product to be treated, or through a gas cooling system above the waste product to be treated, or dividing it and conducting a partial flow through the waste product and another partial flow above the waste product.Preferably, a gypsum suspension is used as an aqueous absorption agent.
