Title: Beverage maker for freshly brewed drinks - incorporates piston releasing perforated base to release excess pressure upwards to not affect coffee grains etc
Inventor: WITTENBORG POUL ERIK
IPC: A47J31/36
Filed: 1974-07-23
Abstract: The beverage maker which is used for freshly brewing coffee or tea etc comprises a cylindrical container (4) with a perforated base (19) and piston (21) wherein as the piston rises the hot water and coffee grains etc are supplied to the container through a valve in the piston and as the piston moves downwards the liquid coffee is pressed through the perforated base (19) which is subsequently released but only when the piston (21) has passed its base position and has opened so that the pressure in the container (4) is reduced to atmospheric pressure. The excess pressure in the container can thereby only escape up throught the piston which prevents the coffee residue from being forced out unevenly so that it can then be rinsed out with water or during the next brew.

Title: Photographic camera with electronic shutter - has timing element automatically adjusted to give minimum exposure to obtain usable photographs
Inventor: LERMANN PETER DIPL ING DR
IPC: G03B7/083
Filed: 1975-08-02
Abstract: A photographic camera has an electronic shutter with a timing element consisting of a light sensor and a capacitor. The light density-resistance characteristic of the light sensor can be adjusted to lower light density values according to the film being used, by connecting in parallel a resistor in the exposure time range between min. time (e.g. 1/500 sec.) and max. time (e.g. 1/30 sec.) for manual exposure. The adjustment is made so that light density at the moment of max. time is still sufficient to take correctly exposed photographs, using the exposure clearance of the film being used. A controllable semiconductor is connected in series with the parallel resistor. The control signal for this semiconductor is derived from an exposure measuring circuit.
