Abstract: To determine the quantity of solid material in a liquid, a beam of light is passed into the liquid through a gas-liquid interface window; the meniscus of said window is periodically or continuously renewed by a current of gas and the scattering or transmission of the light in the liquid is determined by a detector. The device for carry out this determination comprises a sensor (1) to be immersed in the liquid said sensor having an internal chamber (5) into which there debouch at least a gas inlet channel (6), a gas removal channel (7), a means (8) for supplying light and a channel (9) for forming a meniscus (10). This channel is disposed directly opposite said means (8). The sensor is biologically and chemically inert and is capable of being sterilized at approximately 120 DEG C. Contamination and build-up of solid constituents on interface surfaces can be avoided or corrected. The cost price is low and a reasonable measurement result even with a relatively high density of the dispersed solid constituents is achieved. The sensor is able to function in coloured and turbulent solutions.

Abstract: A seat or chair especially for a flight attendant in an aircraft has a backrest section and a seat section hinged to each other and to a frame in such a way that the backrest section and the seat section can take up different angular positions relative to each other and relative to a vertical frame or to the horizontal. Thus, the chair can be folded to take up several positions including positions in which the seat section takes up lower or higher elevations above the floor. For this purpose the upper end of the back rest section is pivotally guided in a guide mechanism while the lower end of the backrest section is journalled to the rear portion of the seat section at a journal axis which simultaneously forms the journal axis of a support and guide member also hinged to the seat section. The support and guide member is hinged intermediate its ends to the frame through a fixed journal so that the rear edge of the support and guide member can engage a stop in the frame. The guide mechanism at the upper end of the frame permits a tilting motion and a linear sliding motion of the upper end of the backrest section. Thus, the seat section, the backrest section, and the support and guide member together form a type of crank drive. Several positions of the chair may be adjusted, including a lower seat position in which the seat section is slanted relative to the horizontal for an increased comfort.

Abstract: The invention relates to a process for the lithographic production of galvanically shaped microstructures having a triangular or trapezoidal cross section of resist material. 
<??>A process is to be specified by means of which microstructures having a triangular or trapezoidal cross section can be produced using the conventional masks with vertical walls. The inclination of the microstructural walls of the structures generated should be freely selectable within wide limits without changing the mask structure. 
<??>According to the invention, the object is achieved by the fact that the resist layer is rotated by an angle +  alpha  with respect to a plane defined perpendicularly to the incident radiation during a first irradiation, then the resist layer is rotated by the angle -  alpha  with respect to the plane defined perpendicularly to the incident radiation during a second irradiation, during which process the areas irradiated during the first irradiation and during the second irradiation overlap at the interface between resist layer and base, whereafter the resist layer is developed in a manner known per se.
