Abstract: The invention relates to a system for the pyrolysis of waste material, in particular to the depolymerization of comminuted old tire material, and for producing an output material which can be further processed to form recovered carbon black. The system comprises at least one rotary kiln reactor, a quenching unit and burner unit. The rotary kiln reactor has a reactor drum, rotating during operation about a longitudinal axis, the interior of which has at least one heating zone, a reaction zone and a degassing zone. The burner unit is designed to burn pyrolysis gas to form a heating gas and to generate a heating gas flow through the heating jacket space, and is for this purpose connected to the heating jacket housing by way of heating gas lines.

Abstract: A device and method for measuring precipitation, in particular snowfall or hail, which has a measuring chamber for receiving a precipitation particle, at least one light source for radiating the measuring chamber with light, and at least one sensor for sensing an intensity of the light radiating through the measuring chamber. At least two measurement areas, which are arranged one below the other, are provided in the measuring chamber, and the intensity of the light radiating through each of the measurement areas can be detected separately.

Abstract: A method for detecting a precipitation particle, and a precipitation sensor, especially a hail sensor, which includes an impact body, a transducer for registering vibrations caused by impact of at least one precipitation particle on the impact body, and a device for evaluating the electrical signals generated by the transducer. The evaluation device is provided for the purpose of separately evaluating the signals generated by the transducer in successive measurement time intervals after impact to determine the kinetic energy of the precipitation particle.

Abstract: The present invention pertains to the use of carbon black for incorporation into a polymer to produce a compound having a defined volume resistivity, wherein the carbon black is obtainable by pyrolysis of carbon black filled crosslinked and/or un-crosslinked polymers, particularly by pyrolysis of cured or uncured carbon black containing rubber compounds, e.g., 5 of used tires. The invention further pertains to a method for producing a compound having a defined volume resistivity, comprising incorporating such pyrolysis carbon black into a polymer. Also described are compounds of defined volume resistivity, comprising a polymer and such pyrolysis carbon black, as well as their use as an antistatic or conductive material.

Abstract: Method for comminuting and cleaning waste plastic, in particular, mixed plastic (MKS) with the following steps: a compacted material, especially, an agglomerate is produced from film scraps or film remnants comminuted into flakes and/or thick-walled plastic parts chopped up into chips, the compacted material is introduced into a disc or drum refiner and is ground therein in the presence of water, wherein the portion of compacted material of the goods located in the refiner amounts to at least 10 percent by weight, a fine grain fraction is removed from the ground stock exiting from the refiner, the remaining ground stock is washed and either mechanically dewatered and dried, or pulverized again in a further refiner stage in the presence of water, and subsequently dewatered and dried.

Abstract: A manual timer switching device has a housing, a program carrier, and a manually rotatable knob. The housing contains a timer switch. The program carrier is rotatably mounted to a front side of the housing, concentric with the housing. The knob is seated coaxially with the program carrier and is rotatable relative to the program carrier to manually control the timer switch via a mechanical connection. The knob has a single ended, bar-shaped operating handle on a front face thereof. The program carrier has a central opening through which the operating handle is seated. The rotating knob can also have a radially extending surface finish or markings near its peripheral circumferential region.

Abstract: An apparatus (10) to carry out a process, in particular for the electrically induced agglomeration of gas-borne particles, contains a closed flow duct (12) through which is directed an aerosol containing particles (14). For the purpose of the bipolar charging of the aerosol, at least one electrode pair (20, 22) is arranged in the flow duct (12), the electrode (20) being wired, so as to be ungrounded, to the negative pole of a current source, the strength of which is sufficient to produce a corona discharge between the electrodes (20 and 22). The electrodes (20 and 22) of each electrode pair are designed to be needle-shaped and are arranged to be insulated with respect to the flow duct walls, such that their tips (26) are disposed opposite each other.

Abstract: A method for reprocessing scrap rubber, which produces reclaimed rubber from comminuted scrap rubber after devulcanization, in a biotechnology-type of process, by holding the comminuted scrap rubber in a bacterial suspension of chemolithotropic microorganisms with a supply of air, until sulphur as an elementary sulphur and/or sulfuric acid is separated from the remaining replasticized reclaimed rubber. This biotechnological reprocessing obtains reclaimed rubber and sulphur in a simplified manner which products can be reused.
