Publication number: 20140001860Abstract: A fast bus transfer method and a device reduce the impact on a load connected to a bus caused by a power cut. The method includes calculating the amplitude of the voltage vector difference between the bus and the backup power supply and the phase angle difference between the bus and the backup power supply; and transferring the load on the bus to the backup power supply only when the amplitude is less than its limit value and the phase angle difference is less than 90°. The device contains a detection module, a calculation module, a comparison module, and a transfer module. By calculating the real-time residual voltage, it is unnecessary for a user to know all the details of the residual voltage characteristic, and can achieve fast transfer simply by setting the limit of the voltage difference when a circuit breaker of the backup power supply is closed.Type: ApplicationFiled: February 28, 2012Publication date: January 2, 2014Inventors: Zhen Cao, Xin Bo Gu, Dieter Kramer, Qui Gun Miao, Lei Ming Qin

Patent number: 6820017Abstract: A method for determining the amplitude and phase angle of a measuring signal corresponding to a current or a voltage on an electrical power supply network by using sampled values of the measuring signal, a model of the measuring signal containing at least a sinusoidal component being used to calculate the amplitude and phase of the measuring signal with the sampled values by applying a recursive least-squares estimation method. In order to be able to determine the frequency of the measuring signal together with the amplitude and the phase angle, use is made of a model of the measuring signal in accordance with the relationship y=A·sin(2&pgr;ft+&phgr;), and by using this model and the sampled values (ym), the determination of the frequency of the measuring signal (um) as well is carried out via a recursive nonlinear least-squares estimation method. By expanding the signal model, measuring signals with a DC component and with frequencies that change over time also can be investigated.Type: GrantFiled: January 22, 2002Date of Patent: November 16, 2004Assignee: Siemens AktiengesellschaftInventors: Andreas Jurisch, Dieter Kramer

Patent number: 5851058Abstract: A tensioning device has an inner end plate mounted on a frame, a sleeve fixed to the end plate and extending along an axis toward an idler wheel over which is spanned a flexible endless element (e.g. a drive chain or conveyor belt), and an axially compressible stack of inner and outer spring rings. The stack is closely surrounded by the sleeve, forms an annular friction spring, and has one end bearing axially on the plate and an opposite end. An outer end plate bears axially toward the frame end plate on the opposite end of the annular friction spring, and a hydraulic unit is braced axially between the outer end plate and the idler wheel. The inner spring rings have substantially frustoconical outer surfaces and the outer spring rings have substantially frustoconical inner surfaces engaging the outer surfaces of the inner rings.Type: GrantFiled: October 11, 1996Date of Patent: December 22, 1998Assignee: Intertractor AktiengesellschaftInventors: Holger Humbek, Heinz-Dieter Kramer

Patent number: 4790007Abstract: A telephone instrument is designed in the shape of an angle, whereby the upper side has a steeper inclination towards the user. The rear wall is at approximately a right angle to the upper side. The bottom side runs at a specific distance, parallel to the upper side and to the rear wall. Since the distance between the upper side and the bottom side is not very great, i.e. since a maximum of only two printed circuit boards can be accommodated one on top of the other in this space, the bottom side below the upper side has a trough which serves both to accommodate an additional printed circuit board and to provide cable entries. This trough does not extend over the total width of the telephone instrument but is narrower. In order to expand the keyboard, one part of the upper side can be moved in the longitudinal direction, away from the user, so that an additional keyboard or indicator device below it is made available.Type: GrantFiled: January 23, 1987Date of Patent: December 6, 1988Assignee: Telenorma Telefonbau und Normalzeit GmbHInventors: Ludwig Richter, Karl H.

Patent number: 4782522Abstract: A terminal of a telephone switchboard installation with one dialing and one service and/or input keyboard and one or more indicator device(s) and a cradle for the hand set. The terminal includes, on the upper side of the terminal a sliding part, which is formed by the upper side which accommodates the keyboards and sometimes includes an indicator device. In one position, the sliding part operationalizes an additional keyboard or indicator device which is located beneath it. This additional keyboard may be designed as a targeted dialing key set, an alpha-numerical input keyboard, etc., and in addition, the keyboard may be replaced with a bank of lamps indicating lines in use.Type: GrantFiled: January 23, 1987Date of Patent: November 1, 1988Assignee: Telenorma Telefonbau und Normalzeit GmbHInventors: Dieter Kramer, Gerhard Sussner, Wolfgang Girscher, Karl-Heinz Niederhofer, Werner Beck, Bernd Ogorczyk
