Patent EP-0283895-A1 (EP)
Inventor: FROHLICH PAUL DIPL-ING
IPC: H02H3/04
Filed: 1988-03-14
Abstract: The invention relates to an electrical protection apparatus for fault monitoring in electrical apparatuses, preferably electrical machines, having a device for detecting the fault and a fault- dependent trip and test or reset device. The test device is in this case designed such that, after activation of a test cycle and emission of a trip signal, the test function is automatically interrupted as a function of time, and such that, once this time or a further test cycle has elapsed, the reset process takes place by passivation of the test device. <IMAGE>
Patent EP-0284023-A1 (EP)
Inventor: TROCCIOLA JOHN CHARLES
IPC: H01M8/06
Filed: 1988-03-22
Abstract: The fuel cell system is adapted to be able to operate with oxygen-contaminated hydrogen-rich fuel gases without experiencing undesirably high temperature hot spots on the fuel cell electrodes. Oxygen in the fuel gas is catalytically burned in areas of the electrodes where no electrochemical reaction occurs. The oxygen content of the fuel gases is thus reduced to an acceptable level before the fuel gases flow over the portions of the electrodes which are electrochemically active. Anode exhaust can also be partially recirculated into the anode inlet to mix with incoming fuel gas thereby preliminarily diluting the amount of oxygen in the incoming fuel gases.

IPC: C12M1/12
Filed: 1988-04-16
Abstract: The process entails a one-stage fermentation with at least one subsequent washing stage which is operated continuously, there being microfiltration stages downstream of the fermentation and of the washing stage or stages in each case. The fermentation and the washing stage or the washing stages with the microfiltration stages result in retention and concentration of the microorganisms. As a consequence of the decoupling of the liquid phase from the solid phase, the washing liquid can be introduced in an amount needed for the process to take place into the last washing stage, and transferred, in each case as permeate stream, into the preceding treatment stage as far as the fermenter.

Title: Hollow shaft with driving elements affixed by means of expansion and with axially differing material properties
Inventor: SWARS HELMUT DIPL-ING
IPC: B21D26/02
Filed: 1988-05-11
Abstract: Drive elements, particularly cams (2), are affixed on a hollow shaft (1) in such a manner that specific sections of the same (11) are expanded, i.e. plastically deformed. In this case, the opposite regions of the cams are elastically deformed. If these regions include brittle, e.g. hardened, material, there is a risk of crack formation. It is thus proposed that the cams be split into a first section (21), consisting of a material with a low expansion capability, and into a second section (22), consisting of a material with a high expansion capability, and that only the latter be subjected to deformation by the expansion process.

IPC: F24D19/10
Filed: 1988-08-17
Abstract: A circulation pump in the form of a wet-operating unit for an AC connection with an operational capacitor to be built in gas boilers. Previously a mechanically operated flow switch was usually inserted in the boilers. The switch interrupts the supply of fuel to the boiler when the flow has decreased to a minimum water flow. The present invention shows how to avoid flow switches, the ratio of the supply voltage to the voltage measured across the operational capacitor being utilized for determining the volume flow and for interrupting the supply of heat if the flow drops below the predetermined minimum value of the volume flow.

Abstract: A p-n junction which emerges at a principal face (2) of the semiconductor substrate (1) at an edge of the heavily doped zone (3) is formed in a semiconductor element by the heavily doped zone (3) which penetrates the semiconductor substrate (1) from the principal surface (2) and is laterally limited and by a lightly doped zone surrounding the heavily doped zone. The edge of the heavily doped zone (3) is formed by a guard zone (6b) whose doping density slowly decreases in a direction parallel to the principal surface (2) from the heavily doped zone (3) towards the p-n junction. A surface breakdown of the p-n junction is prevented by the guard zone (6b) having a maximum penetration depth near the heavily doped zone (3) and by the maximum penetration depth of the guard zone (6b) being greater than the penetration depth of the adjacent heavily doped zone (3). The guard zone (6b) has a maximum doping density which does not substantially exceed 10<1><5> cm<-><3>, a width which is comparable to a thickness of the lightly doped zone and a maximum penetration depth which is between 40  mu m and 80  mu m. The doping density of the guard zone (6b) drops approximately linearly or in step form in a direction parallel to the principal surface (2). …<IMAGE>…
