Patent DE-2729561-A1 (DE)
Title: Combined radiator and convection room heater - has warm air fan positioned between two radiators and thermostatically controlled
IPC: F28D1/02
Filed: 1977-06-30
Abstract: The heater consists of a conventional radiator acting selectively with a convector. The fan of the convector blows the warm air partly towards the floor, and partly direct into the room.

Title: Reversibly swellable hydrophilic lamellar mineral - with unidirectional shrinkage on drying, useful as carrier, refractory binder and release agent
Inventor: DABROWSKI RALF
IPC: C04B32/00
Filed: 1977-07-11
Abstract: Mineral is based on a reversibly swellable 3-layer mineral of large-faced crystalline type, with disconnected crystal layer. This is produced from fine-grained vermiculite, hydro-mica or even nonswellable mineral with these minerals deposited within the crystals with >50 (>75)wt. % tabular crystals with extremely thin, uniformly planae tubular crystals with a thickness of 0.5-10(0.5-5) mu m and face dimensions corresponding to an equiv. dia. of 10-200 mu m and a ratio of thickness/equiv. dia. =1.10, (=1.20). The particles have hydrophilic properties at the planar faces, which rapidly take up or yield polar liquids, such as water, and strong adhesion or cohesion, which leads to shrinkage only in one direction, i.e. perpendicular to the tabular plane, on drying the particles from a dispersion in a polar liquid (water) or moistening the dray material. The particles lie over one another in layers and gave a plasticity of 35-65 wt. % dry material w.r.t. the moist material. Mineral is used partic. as refractory binder for the prodn. of mouldings and films and as release agent. It is also useful as carrier for various materials, e.g. plant protection agents.

Title: Audio signal processor for motorcycle helmets - uses bandpass, notch and active filters and amplifier with AGC
Inventor: HAUSER FRANZ ING GRAD
IPC: H04R3/00
Filed: 1978-09-22
Abstract: The audio filter circuit overcomes the acoustic problems associated with ambient noise encountered by the rider of a motorcycle wearing a helmet fitted with loudspeakers. The audio signal is first fed to a band-pass filter those pass-band extends from approx. 100 Hz to an upper limit of approx. 6 kHz. This eliminates interference effects. Since only small loudspeakers can be fitted into the helmet, their resonant frequency is likely to fall within the pass-band of the filter. The band-pass filter is therefore followed by a notch filter whose effective frequency equals the loudspeaker resonant frequency. An active filter with a peak response at about 400 Hz is combined with the notch filter. The resulting signal is fed to an amplifier with a.g.c.
