Abstract: A heating device, in particular a vehicle heating device, is indicated, which has an operation control and a combustion air blower, driven by a motor, for combustion air supply to a burner operated by means of fuel. In this connection, an electronic drive device for the combustion air blower is prepared which works in such a manner that the heating capacity produced by the heating device is independent of external disturbance variables such as system voltage fluctuations, bearing friction, pressure losses at the burner and counter-pressure produced by the waste gas or the like. According to one embodiment, the electronic drive device has the effect that a constant voltage is present at the combustion air blower motor so that the speed of the combustion air blower is extensively constant. Alternatively, the electronic drive device can also effect regulation of the electromotive force of the combustion air blower motor to a setpoint predetermined as a desired value.

Abstract: A burner, especially a forced-draught burner, for boilers, incineration plants or the like is proposed which is provided with an air feed device, a fuel feed device (15) for injecting a liquid or gaseous fuel, a flame device (14) extending into a combustion chamber (11) and producing the burner flame (18) and a flue gas recirculation channel (20) which recirculates some of the flue gases produced during the incineration to the air feed device. Provided in the boiler-side connection region of the flue gas recirculation channel (20) is a converter element (21) which converts solid particles into gaseous constituents and is preferably composed of a porous ceramic material. As a result of the position of the converter element (21) it is heated by the hot flue gases to a temperature of 400-600 DEG C, with the result that the soot and dust particles in the flue gas are burnt and are carried off as gaseous constituents. This prevents contamination of the burner (13), accompanied by maintenance-free operation of the converter element (21). <IMAGE>

Abstract: In a tube bending machine with an elongate machine frame (11) of a receiving device (32) for a bending mandrel and a feed carriage (25) with a clamping sleeve (6) for clamping a tube, the receiving device (32) for the bending mandrel and the feed carriage (25) is provided with guides for a displacement transversely to the longitudinal direction (8) of the machine frame (11). Arranged at a head end of the machine frame (11) is a bending table (13) with bending forms (36, 37). A swivel arm (7) with a gripping jaw (41) can be swivelled about a vertical axis (38) to carry out the bending. In order to be able to bend a tube to be processed either to the left or to the right and/or with bending radii of various sizes, it is proposed that the feed carriage (25) with the clamping sleeve (6) should be arranged in such a way that it can be displaced in the longitudinal direction (8) of the machine frame (11) along a longitudinal guide (15), and that the feed carriage (25), the receiving device (32) for the bending mandrel and the longitudinal guide (15) together form a displacement unit which can be moved jointly transversely to the longitudinal direction (8) of the machine frame (11). The bending table (13) should furthermore be mounted so as to be rotatable parallel to the longitudinal direction (8) of the machine frame (11) about an axis (14). One of the bending forms (36, 37), one gripping jaw (41, 42) and one slide rail (47, 48) is arranged on each side of the axis (14). The bending forms (36, 37) can be moved alternately into a working position or standby position by rotating the bending table (13). <IMAGE>

Abstract: A drive circuit arrangement for an invertor (20) in an electronic ballast (1,EVG) which can be connected between a mains voltage supply and one or more gas discharge lamps (GE). An intermediate circuit DC supply voltage (U0) and a series circuit, which can be connected thereto, consisting of at least one ''upper'' and one ''lower'' semiconductor switch, which are provided such that they can be switched on and off alternately. At least one of the power semiconductor switches that are connected in series can be controlled via a control input (B,G). Such a drive circuit is to be designed such that the power semiconductors can be driven in a low-cost manner, and immune to interference, especially when the drive reference potential is changing. This is achieved in that the alternating output AC voltage (uw) which is emitted between the two semiconductor switches (S1,D1,S2) to a load circuit containing the gas discharge lamp (GE) is independent of a control signal or signals (u1,u2,u2<'>, ust) supplied to the control circuit or circuits (32,31,V1,V2), and such that the control signal (u2) of the control circuit (32,V2,K2) can be supplied to said control circuit (32,V2,K2) of at least one controllable power semiconductor (S1,S2) via a current/voltage converter circuit (50,51,Rx), which is connected in DC terms, as a displaced-level control signal (ux,u2<'>). A method for driving at least one power switching element (S1,S2) and the use of a current-controlled or voltage-controlled current source or sink (51,50,T4,R4,OV) are also specified. <IMAGE>

Abstract: Described is an improved method and apparatus which allows graceful insertion/de-insertion of a station into an FDDI network. A circuit arrangement known as "Roving MAC" captures a local token which is circulating on a local loop established between the Roving MAC and the station. The "Roving MAC" issues void frames while holding the local token. A circuit arrangement monitors the FDDI network. If the token on the FDDI network is sensed before the local token is released, a data frame is allowed to pass through, but the token concatenated to the data frame is switched into the device thus joining it to the FDDI network. A scrubber circuit simultaneously removes the void frames and issues idle signals on the FDDI network.

Abstract: An output circuit which is provided with an integrated circuit (1) composed of a PNP (102,201) transistor and an NPN transistor (102,202) of which the base is connected to the collector of the PNP transistor (102,201), a voltage source for supplying an electric potential to the emitter of the PNP transistor and voltage dropping means (2) provided outside the integrated circuit (1) for making the electric potential supplied to the collector of the NPN transistor (102,202) less than the electric potential of the voltage source. Thereby, an electric potential supplied to the NPN transistor (102,202) can be decreased because a voltage drop is caused by an element provided outside the integrated circuit. Thus, power consumption in the NPN transistor (102,202) can be decreased. Namely, power consumed in the integrated circuit (1) can be reduced. Consequently, high packaging density of the integrated circuit can be achieved and provision of multiple channels in the integrated circuit can be realized.
