Title: Flexible perforated foil for dry shaver - has lattice pattern to provide shearing edges at most effective angle
Inventor: BRUCHER EGON
IPC: B26B19/38
Filed: 1973-10-15
Abstract: The flexible perforated foil is formed into an arc so that it just touches the tips of the rotating blades of the shaver head. The longitudinal members run in the direction of rotation of the blade rotor whilst the transverse members are at an angle forming parallelograms. A hair is pushed to a corner by the action of the blade and then cut off close to the surface. The lattice pattern is so formed that all the intersections of the cross members and the longitudinal members lie in straight lines. This arrangement provides a high degree of flexibility in the foil and ensures that it always maintains contact with the blades.

Title: Infrared photometric detection of inorg impurities in water - using separate wavelength ranges for detection of aromatics and aliphatics
Inventor: BERTHOLD RAINER DIPL-PHYS
IPC: G01N21/31
Filed: 1973-11-07
Abstract: A method of continuously summating the concentration of organic substances in water operates by infrared photometry using two separate wavelength ranges; one in which all organic substances absorb, the other in which they do not absorb; the quotient or difference is obtained. The former range is subdivided into a range in which the aromatics absorb and another range in which the aliphatics absorb; the natural difference in their extinction coefficients is compensated by multiplying the reading for the aromatic compounds by a factor corresponding to the ratio between the extinction coefficients. More specif., the former range is subdivided into three ranges; in which the aromatic, the aliphatic and the aliphatic-aromatic substances absorb.
