Abstract: The invention relates to an air purification device for reducing pollutants in the air. Said device comprises an ioniser, which is exposed to an air flow and impinged upon by an ionization power from a drive stage for ionising the air that is supplied by the air flow, and a gas sensor for measuring pollutant concentrations. To provide an air purification device, which purifies the air according to requirements even if the pollutant concentrations change rapidly and/or have extreme values, the driver stage, ionizer and gas sensor co-operate with a controller in a closed loop control circuit, in such a way that the output signal of the gas sensor essentially corresponds to a predetermined target value.

Abstract: A method and device for reading out a fiber gyroscope based on the concept of determining, by gating the light signal for particular time intervals, only one particular phase section of the read-out signal of a photodetector of the fiber optic gyroscope modulated with a periodic function. Further phase sections are determined in sequence and cyclically in the same manner so that the entire photodetector signal is detected after one full cycle. Signals associated with individual phase sections are averaged separately and processed to obtain a rotation rate-proportional signal. The read-out signals can also be processed so that a control signal for deviation of the phase modulator is obtained and/or the gyroscope scale factor is stabilized.

Abstract: A lower tool support for a stamping machine or the like having a lower frame and a tool saddle with a saddle plate, movably disposed on the saddle surface of the lower frame, with adjusting devices for the adjustment of the tool saddle in relation to the lower frame in the plane of the saddle surface and an arresting device for fixing the tool saddle on the lower frame being provided, the saddle plate of the tool saddle having at least one lower flange and the arresting device having at least one fastening flange formfittingly overlapping the lower flange, the fastening flange in the plane of the saddle surface having an exactly determined relative position in respect to the lower frame, thus securing the saddle plate against vertical lifting from the saddle surface.

Abstract: Method and apparatus for angular rate measurement and digital angular rate readout by means of a fiber interferometer using the Sagnac effect. Three component light beams are generated by means of an acousto-optical modulator which is operated in the Raman-Nath region. One component light beam is introduced unmodulated in a first direction into a fiber coil while the second and third component light beams are introduced with raised and lowered frequencies, respectively in the opposite direction. After passing through the coil, the component light beams are received by a photodetector and fed to controllers for generating the differential frequencies. Weighted, the differential frequencies are subtracted from each other or summed and evaluated as the angular rate and/or measures of the temperature of the fiber coil.

Abstract: A method and apparatus for reading out angular rates by means of a passive optical resonator provides for the generation of three component light beams individually tuned to distinct resonator modes. One component light beam is radiated into the resonator in the opposite direction to the two other component light beams. By means of an evaluating logic, differences are formed between the counterrotating light beams and the differences weighted and subtracted from each other to provide angular rate. The optical length of the resonator, and, thus, temperature are available as a weighted sum of the differences. Temperature drift may be eliminated from angular rate measurements by compensation according to the invention.

Abstract: An angle shear for cutting profile steel has generally parallel and spaced front and rear frame plates fixed relative to each other, at least one fixed blade carried on the front plate, a working slide displaceable vertically between the frame plates, and individual guide rails extending at an acute angle of generally 45.degree. to the vertical and secured to one of the frame plates. An angle slide displaceable along the guides generally at 45.degree. to the vertical between the plates carries a movable blade displaceable past the fixed blade. Formations link the slides for joint synchronous movement between the plates. Both slides move in generally the same plane and have front and rear faces directly confronting and engaging the front and rear plates, respectively.

Clamps secure the holddown plate in the use position against the frame plate with limited pivoting about the horizontal axis only.

Abstract: A power shear has a pair of parallel frame plates spaced apart to either side of a fixed blade and a movable blade. The movable blade can be displaced past the fixed blade to shear a workpiece extending across the plane and resting on the fixed blade A holddown plate is slidably mounted in rails on one of the frame plates and has a pair of edges guided by the rails and overreached by teeth formed on these rails. These edges of the holddown plate are formed with notches that can be aligned with the teeth to allow removal of the holddown plate in a direction perpendicular to its plane. A positioning spindle threaded through a nut fixed on the one frame plate can have an enlarged head engaged in a T-shaped cutout of the holddown plate so that when the holddown plate is lifted perpendicularly off the frame plate it is also disengaged from the positioning spindle.

Abstract: A metalworking machine such as a punch or shear has a pair of substantially parallel and spaced-apart frame plates which are mounted fixedly relative to each other and which flank a vertically displaceable work slide formed at its upper edge with a T-shaped notch.

The piston and slide can be separated from each other by relative lateral displacement perpendicular to the plane of the slide.
