Title: Isolator switch for fitting to vehicle batteries wired in vehicle's load current circuit, has arrangement of contacts and allows electromagnetic system to release isolator element from normal operating position
Inventor: KERN JOSEF
IPC: H01H73/44
Filed: 1999-04-01
Abstract: A battery isolator switch is wired in a vehicle's load current circuit with an arrangement of contacts (7-9). During a fault an electromagnetic system releases an isolator element from a normal operating position to use its spring force to move it into an isolating position. A wedge-shaped isolating section (11) isolates the contacts and causes an electric arc to be extinguished. A restoring mechanism puts the isolating element back into its normal operating position.

Patent DE-19926388-A1 (DE)
Inventor: BYATT JOHN ANTHONY
IPC: G01N9/24
Filed: 1999-06-10
Abstract: The invention relates to a sensor (1) for measuring density profile using gamma rays (5), which is particularly suitable for measuring the level in oil separator tanks. The known measuring principle involves conducting locally resolved measurement of a density-dependent gamma ray transmission of a medium (6a, 6b, 6c) by a vertical linear array (13) of photomultipliers( 7) and using said measurement to determine the location of an oil/water (6c) boundary layer. According to the invention, the gamma ray density sensor (1) is equipped with PIN photodiodes (10) instead of photomultipliers (7). Means for passive cooling for said photodiodes (10) are also provided. This considerably simplifies the structure, operation and maintenance of the sensor and improves local resolution and service life of the sensor (1). Passive cooling can be easily realized by building a thermal bridge (12) between the warm photodiodes (10) and the cool ambient medium or the cool wall (14) of the separator tank. Usability of the sensor (1) under difficult operating conditions and in non-easily accessible locations is generally improved.
Patent DE-19928309-A1 (DE)
Inventor: BAYER ERICH
IPC: H02M3/07
Filed: 1999-06-21
Abstract: The invention relates to a DC/DC converter operating on the principle of a charge pump and comprising a first capacitor C1 alternatingly charged via four MOSFETs M1-M4 to the input voltage and then discharged in series with the input voltage via a second capacitor C2 connected to the output of the circuit. To set the starting current for charging the as yet empty capacitors to a precisely defined small value a switchable current mirror M3, M5 is used comprising one of the four MOSFETs (M3) and a further small MOSFET (M5) which is connected to a current source 4. A comparator 5 handles selection between the starting phase and the normal charge pump mode by comparing the output voltage Vout of the converter to a reference voltage Vref, it switching the current mirror and - via two small switches S2 and S3 connected to the gates of two of the four MOSFETs - also two of the four MOSFETs so that the capacitors may be charged in an energy-saving way. As compared to existing more complicated achievements this novel DC/DC converter is producable integrated on a smaller circuit area, it in addition to this taking into account the short-circuit case of the converter. In one special embodiment a foldback effect is achievable via a further MOSFET connected in parallel to the current source, the gate of this MOSFET being connected to the output of the converter.  <IMAGE>

Title: Papermaking machine transfer system carries band of paper from formation to pressing section with pick-up and suction roller system
Inventor: LAURIKAINEN MAURI
IPC: D21F3/04
Filed: 1999-06-29
Abstract: An upper production sieve (15) is arranged to run around the pick-up suction roller (13). The band (W) is taken up from a pick-up position (P) and carried from the production sieve (15), over the suction zone (13a) of the pick-up suction roller (13) to the transfer gap (N1). It is carried over on the upper surface of the press filter (30) into the pressing section, under closed guidance.  Preferred features: The transfer gap is implemented between a pressing felt inside the pressing suction roller and the pick-up suction roller, such that in the transfer gap, which is comparatively lightly-loaded, the band is picked up under reduced pressure from the production sieve or corresponding transfer sieve for transfer onto the upper surface of the pressing felt. This serves as a pressing cloth in the first de-watering press gap (NP1) or the press sections (NP1, NP2). The transfer gap is lightly loaded such that little water is removed. The linear pressure is about 10-80 kN/m and/or the reduced pressure of the pick-up suction roller and the suction zones (13a, 38a) is about -1 to -50 kPa. The equipment and its variations on the above principles are further detailed in the disclosure.
