Title: Plate-form filter esp. for kitchen vapour outlets - prevents settling of filtration mass forming open passage
Inventor: DEININGER ANTON ING GRAD
IPC: F24C15/20
Filed: 1977-03-31
Abstract: A plate-form filter, esp. a filter for eliminating the odours in the vapours expelled through a cowl from a kitchen, has a support frame divided into a number of compartments by intercrossing ribs. In each compartment there is a loosely packed filtration mass, e.g. granular active C, retained between air-permeable covers on each side of the frame. The difficulty with this type of filter, that the settling of the filtration mass leaves a free passage through for the vapour is overcome. Intensive contact between the vapours and the carbon is ensured by an arrangement in which the shortest distance to which the ribs of the frame project vertically, is greater than the height of the free space left by the settling of the mass inthe compartments.

Title: Hydroelectric power generating system - has water-driven wheels mounted on frame supported by floats to give constant depth of immersion and aeration of water
Inventor: REPPERT RUEDIGER LOTHAR VON DI
IPC: C02F3/12
Filed: 1977-06-24
Abstract: Several water wheels proportioned for the volume flow in a river are connected by gear wheels to electrical generators. The assembly is mounted on a frame equipped with floats so that depth of immersion of the wheels does not vary with the water level in the river. The assembly does not extract the whole of the energy in the flowing water and a series of such assemblies is put at intervals along the river. The water is broken up by the wheels and throughly mixed with the oxygen in the air before returning to the river. It absorbs oxygen during this process which increases its capacity for biological purification.

Title: Controlled amplifier reference setter for low RF - using antiparallel and antiseries-connected diode network, with latter diode cathodes coupled via capacitor
Inventor: SCHMID WOLFGANG ING GRAD
IPC: H03H5/12
Filed: 1978-11-08
Abstract: The object is to produce a two-pole diode bridge reference setter for use in the frequency range 312kHz to 4028kHz. Conventional bridges for this function, employing high frequency diodes, do not operate satisfactorily at frequencies lower than about 10MHz. The required diode network can be produced by adding anti-series connected diodes (D5, D6) to the anti-parallel connected diodes (D1, D2; D3, D4). The cathodes of the anti-series pair are coupled by a capacitor (C8). The diodes are thus all in series for dc components and in anti-parallel anti-series configuration for ac components. The anti-parallel paths are symmetrical, having identical diodes and capacitors (C4, C5, C6) connecting them to the one two pole terminal (2) and effective earth. This assists in reducing ringing and distortion.
