Patent DE-4403077-A1 (DE)
Title: Circuit arrangement for an AC converter and method for operation
Inventor: BERGMANN LUTZ DIPL ING
IPC: G01R15/18
Filed: 1994-02-02
Abstract: A circuit arrangement is proposed for an AC converter (1) which is connected via its primary winding (2) to a measurement circuit and whose secondary winding (3) is connected to a load (8), the load voltage (Ub) produced between the output terminals (13, 14) being a measure of the alternating current flowing on the primary side. A power amplifier (10) is provided whose inverting input (9) is connected, like the first connection of the load (8) as well, to the first secondary winding connection (6), whose non-inverting input (11) is connected to the second secondary winding connection (7) which is at the reference potential of zero volts, and whose output (12) is connected, like the second connection of the load (8) as well, to the first output terminal (13), while the second output terminal (14) is at the reference potential of zero. Furthermore, a method for operating the circuit arrangement is proposed, the power amplifier (10) keeping the secondary voltage of the current transformer (1) and thus the power output of the secondary winding (3) at approximately zero and at the same time, by representing the AC converter, producing the power which results from the product of the load resistance (Rb) and the square of the secondary current (I2). <IMAGE>

Title: Activated sludge aerator dispenses with the blower room
Inventor: GESNER WALTER
IPC: B01F33/40
Filed: 1994-02-24
Abstract: A procedure and assembly to gasify fluids, particularly suited to the oxygenation of water in an agitation vessel, esp. an activated sludge tank. A pipework aeration grid immersed in the fluid, is used to supply compressed air, which is blown in through pores or slots.

Title: Partial desulphurisation of flue gases using ceramic filter candles
Inventor: HOEHNE HARTMUT DIPL ING
IPC: F23J15/02
Filed: 1994-03-11
Abstract: In a process for the partial desulphurisation of a hot gas generated by the combustion of brown coal, esp. for a gas turbine, the filter candle of a ceramic filter is used for desulphurisation.

Patent DE-4424736-A1 (DE)
Title: Optical coupling arrangement for optical switching
Inventor: HUBER MANFRED N DR ING
IPC: H04Q11/00
Filed: 1994-07-13
Abstract: On the input side each optical signal arriving on the appropriate input fibre (E1,...,Ee) is distributed according to wavelength by the demultiplexers (D1,...,De) before reaching the adjustable wavelength converters (Kl1,...,Kln;...;Ke1,...,Ken). There follows an area-coupling arrangement (R), with, on the output side, multiplexers combining the wavelengths. Optical beam splitters (S1,....Se) individually assigned to the incoming signal fibres (E1,...Ee) multiply the arriving signal into at least two. One of these is fed to the associated wavelength demultiplexer (D1,....De) and the other to a variable optical filter (DF1y,...DFez) leading to a variable wavelength converter (Kly,....Kez) coupler to a further input of the area coupling installation (R).

The effective light outlet surface of the walls, has at least the height of the object. At least one reflector (4) is arranged at the outer edge of the light conductor, which deflects the light of the light conductor to the opening.

Patent DE-4431740-A1 (DE)
Inventor: ZIMMER JAN
IPC: F02M59/46
Filed: 1994-09-06
Abstract: A delivery valve for installation in a delivery line (3) between a fuel injection pump working chamber (5) and an injection point (7) of an internal combustion engine to be supplied by the pump. The delivery valve has a valve body (13) with a valve seat (17) and through passage (15). A delivery-valve closure member (19) which opens against the bias of a spring (25) towards the injection point (7) includes a conical valve-sealing surface (23) which co-operates with the valve seat (17). The delivery valve also has a return-flow valve (39) which opens towards the pump working chamber (5), the movable valve member thereof being constituted by the valve body (13), a Belleville spring holding the latter in contact with fixed seat (45). The combined valve body/member (13) is in the form of a sleeve and is spaced from a housing bore (11) to define an annular passage for the return flow. The arrangement avoids spring breakages in the return-flow valve (39) because it provides a large opening cross-section even when the opening stroke is a minimum. <IMAGE>

Patent DE-4441714-A1 (DE)
Title: Method of mounting glas spanels in door leaves without glazing bars
Inventor: KLIMMT ULRICH
IPC: E06B3/54
Filed: 1994-11-23
Abstract: The patent application relates to a method which permits glass panels to be mounted in door leaves without glazing bars. Up until now, it has been necessary to provide a milled relief in the door leaf, after it has been pressed, in the size of the glass panel and to retain the glass by glazing bars. By means of the method outlined in the patent claim, the glass pane is pushed into a frame, inserted during production, with a profile adapted for the pane, the altter being pushed into the door leaf through a slit milled in on the end side. The advantages are: easy exchange of the glass pane, simpler coating and grinding since there are no protruding bars and corners, an aesthetic value and the elimination of glazing bars. By virtue of the additional use of a metal U-profile, greater strength and thus increased safety against break-in are obtained.
