Title: Wilhelm Pross: Innovator in Photometric Technology

Introduction

Wilhelm Pross is a notable inventor based in Munich, Germany. He has made significant contributions to the field of photometry, with a total of 4 patents to his name. His innovative designs have advanced the technology used for measuring light transparency in various substances.

Latest Patents

One of Pross's latest patents is a photometer designed for measuring the light transparency of a substance. This device utilizes a light beam that illuminates the substance, allowing the light to pass through and strike a photoelement, which generates a measuring current. The voltage produced from this current is logarithmated by a converter circuit and displayed on an indicating instrument. A zero balance control circuit ensures that the indicating instrument returns to a predetermined value based on previous measurements of a calibrated substance. If the transparency of the measured substance matches that of the calibrated one, the device indicates a zero value, while any deviation from zero reflects the difference in transparency.

Another significant invention is a measuring apparatus featuring a zero-balancing arrangement incorporated into a pocket-type device. This portable apparatus can be operated with one hand and includes a battery to power a lamp used as a light source. A cuvet containing the liquid to be measured is positioned in the path of a measuring light beam. The device also features a movable wedge-shaped filter, which can be adjusted manually using a setting wheel. An electronic regulating system is integrated to ensure that the light meter reading is initially set to zero before measuring the specific liquid.
