Abstract: A heatable hollow body for transporting and/or storing liquid, gaseous and/or pasty media, having at least one heatable layer which has an electrically conductive material, is provided, wherein the heatable layer is in direct contact at least partially, preferably largely, particularly preferably fully, with the medium to be heated. In some aspects, the electrically conductive material has such a high electrical resistance that it can heat the heatable layer as a resistance conductor, and the electrically conductive material has such a low electrical resistance that the heatable layer is simultaneously electrically conductive. In some cases, the heatable layer has an elastomeric material or a plastics material in which the electrically conductive material is embedded. Also, the electrically conductive material may be conductive carbon black, a metal powder or carbon nanotubes.

Abstract: A connector arrangement connects an electrically-heatable hose to a piece of equipment. The connector arrangement is configured as a plug connection wherein the hose has a first plug connector which can be plugged into a mating second plug connector mounted on the piece of equipment. The hose has at least one heater lead embedded in the hose and the heater lead has an end segment brought out of the hose for fitting with the first plug connector. The first plug connector includes a body having an annular housing region defining an end. A connector stub is arranged on the end for receiving an end portion of the hose thereon. An annular receptacle is pushed onto the annular housing region and has a surface and a helical slot formed in the surface. The end segment of the heater lead is helically placed in the helical slot so as to spirally cover over the annular housing region.

Abstract: A security service of computer networks having a policy builder, an LDAP-compliant database, a validator and an API. The policy builder component provides a graphical user interface to be used by a policy manager to define access policies for users seeking to access network services and resources. The graphical user interface has a grid of nodes representing access policies. The grid is arranged to correspond to a defined tree structure representing services and resources and a business relationship tree structure representing users. The graphical user interface permits the policy manager to define policy builder plug-ins for access policy customization. The LDAP-compliant database maintains the policy builder plug-ins. The validator component receives requests from users and queries the LDAP-compliant database to obtain relevant access policies as defined by the policy manager.

Abstract: A digital signature is generated in association with target data. The computer generating the digital data encrypts the digital signature using a public key encryption system. The private key is stored in dynamic memory in a secure manner. The public key associated with the private key is stored in an accessible database. The public key is accessed from the database and used by recipient computers to authenticate the target data by decrypting the encrypted digital signature. When the computer generating the digital signature is restarted, the private key stored in dynamic memory is lost. The computer obtains a new private and public key pair from the public key encryption system. The previously used public key is maintained in the database until a predefined time has elapsed, after which it is removed from the database.

Abstract: The invention relates to synergistic stabilizer compositions comprising Hindered Amine Stabilizers (HAS), phenolic antioxidants, and, if appropriate, UV-absorbers, for thermoplastic polymers, especially for polyolefin pipes and other polyolefin molding materials, which are in prolonged contact with water. These mixtures show superior long term performance as measured by standard test methods such as oxidation induction time (OIT).

Abstract: The invention relates to synergistic combinations of certain phenolic antioxidants in thermoplastic polymers, especially in polyolefin pipes and other thermoplastic molding materials which are in prolonged contact with water. The instant combinations lead to better resistance against oxidative degradation as measured in terms of oxidation induction times (OIT), color and other technically important parameters as known in the art.

Abstract: An input device for shifting a marker on a monitor has a completely closed, hermetically sealed and sterilizeable housing with an electrical shield, at least one sensor arrangement for detecting movement of the housing, an evaluation unit connected with the sensor arrangement, and a conversion unit connected to the evaluation unit downstream for converting the signals emitted by the evaluation unit into corresponding modulated signals. The sensor arrangement, the evaluation unit and the conversion unit are arranged entirely within the shield as is a transmitting unit for radiating the modulated signals into the environment, where they are detected by a receiver positioned in the environment and are converted into signals for shifting the marker on the monitor.

Abstract: For the indirect identification of the mass flow of a specimen fluid stre the specimen fluid stream is mixed with a dilution fluid stream to form an total fluid stream that is to be investigated in view of specific constituents of the specimen fluid stream. The mass flow of a specimen fluid stream is identified from the difference between the measured mass flows of the dilution fluid stream and the total fluid stream. In order to reduce the possibilities of error in the setting of a defined dilution ration, the mass flows of the dilution fluid stream and the total fluid stream are calibrated relative to one another, to which end one of the calibration measurements is not undertaken at the respective fluid stream but is separately undertaken at the specimen fluid stream.

Abstract: The dispenser has a circular mixing chamber (8) which is arranged immediately in front of a mixing nozzle (7). A first channel (15) leads to the mixing chamber (8) which is connected with a rising pipe which is immersed in the filled material of a squeezable container. Simultaneously, a second channel (9) leads into the mixing chamber which is connected to the air space above the filled material. A sieve arranged in the outlet channel (19) at a distance after the mixing nozzle which completely covers the outlet channel under the effect of the pressure of the filled material flowing out when the container (1) is squeezed. With release of the container, the sieve partially releases the outlet channel under the suction effect of the air return flow. With that, the container is rapidly ready for a renewed press sequence.

Abstract: When the container is compressed, liquid flows via a riser (2) and an inflow channel (10) tangentially into a vortex chamber (9), where a rotary flow is induced. The liquid is accelerated by the conical cross-section of the inner wall (5) of the liquid nozzle (1) until it is discharged from the orifice (7) of the liquid nozzle (1). At the same time, air from the container flows via an inflow channel (11) into the annular chamber (3) which surrounds the liquid nozzle (1). Coaxial with the liquid nozzle there is a mixture nozzle (4) with a conical inner wall (5'). The orifice (7) of the liquid nozzle (1) is retracted relative to the orifice (8) of the mixture nozzle (4), so that the two media are jointly accelerated after mixing.
