Abstract: In a method for reducing frequency deviations of assigned frequency channels which are provided for data transmission between fixed stations (FS1, FS2 ... FSn) and mobile subscribers (MT1, MT2, MT3 ... MTi) via satellites (SAT), each mobile subscriber (MT1, MT2, MT3 ... MTi) transmits a carrier signal to the relevant communicating fixed station (FS1, FS2 ... FSn), at least before the transmission of user signals, which are preferably speech signals, the frequency deviation of the received carrier signal from the permanently assigned nominal frequency of the relevant signalling channel is detected in this fixed station, whereupon the detected frequency deviation is notified to the mobile subscriber and finally a frequency re-adjustment is carried out in the mobile subscriber so that the frequency used for the subsequent user signal transmission is shifted in relation to the user frequency channel provided for this purpose by the notified frequency deviation, but with a reversed sign. <IMAGE>

Abstract: A method for the production of a triple mirror wheel is described. The steps of the method consist in producing in the first instance three individual parts of the triple mirror wheel, namely a core, which is provided with roof edges rotated through 180 DEG , which roof edges are in each instance adjacent to a mirror side. Two polygonal rings are then produced, which exhibit as the polygonal surfaces the respective third side of the triple mirrors. The core is brought concentrically between two polygonal rings, and the parts are fixedly connected to one another in such a correlation that a triple mirror wheel is formed with adjacent triple mirrors rotated through 180 DEG , with extremely sharp edges on the individual triple mirrors. <IMAGE>

Abstract: In an improved ophtalmic lens which includes a pair of front and back refractive surfaces (1, 2), the curvature of the meridian of the front or back refractive surface sub­stantially increases as far as at least 15 mm in the di­rection of the outer periphery of the lens from the optical axis. The curvature of the meridian may increase monotoni­cally within the extent of at least 15 mm from the optical axis in the direction remote from said axis. Further, when the curvature of the meridian is represented by C (r) as a function of the distance r from the optical axis, the li­near differential coefficient dC/dr of the function C may increase at least once and then decreases as getting re­moter from the optical axis. The improvement is to make the edge of the lens thinner so as to present a good appearance with maintaining a superior optical efficiency.

Abstract: A power supply is disclosed for both arc welding and plasma cutting. The power supply includes an A.C. power source (12), a transformer (TI) having a primary winding receiving power from the A.C. power source and a secondary winding. Power in the secondarywinding is rectified by a rectifier circuit (D1-D4) to provide a first output (14, 16) suitable for arc welding and a second output (24, 26) suitable for plasma cutting. Switches (S1, S2) connected to the rectifier circuit (D1-D4) select between the two outputs. Conventional power supplies employ an inductance for stabilizing the current in the plasma cutting power supply. The power supply may include a circuit path in parallel to the inductance for passing additional current to the torch so that the open circuit voltage applied to the inductance required for sustaining the arc is reduced.

Abstract: The invention relates to a method for optically determining the position and/or direction of travel of at least one driverless vehicle (F) in the x-y plane, comprising transmitting and receiving optics (3) mounted on the vehicle for generating a focused scanning light beam and receiving the reflected beam which is reflected by retroreflectors (R1, R2, R3), arranged separately from the vehicle, to the receiving optics, and with an evaluating and computing device for processing the electrical signals supplied by the receiving optics, the transmitting and receiving optics synchronously and cyclically passing through a predetermined angular range ( alpha ) in the x-y plane. The scanning beam is directed towards at least three retroreflectors (R1, R2, R3) which are located on a straight line and the distances (d) of which from one another are equal and known and the position of which in the x-y coordinate system is specified. The receiving optics (3) detect the instantaneous scanning angle ( alpha 1,  alpha 2,  alpha 3) with respect to a defined longitudinal axis (1) of the vehicle (F) to the three retroreflectors (R1, R2, R3). Using the instantaneous scanning angles ( alpha 1,  alpha 2,  alpha 3) and the distances (d) of the retroreflectors (R1, R2, R3) from one another, the distances (b1, b2, b3) of the receiving optics (3) from the retroreflectors are calculated, as a result of which the triangle spanned by the two outer retroreflectors (R1, R3) and the transmitting and receiving optics (3) is calculated and thus the coordinates (XF, YF) of the vehicle (F) and the vehicle angle ( psi ) of the vehicle (1) are determined, for example the angle ( psi ) spanned by the longitudinal axis (1) of the vehicle (F) and the x axis of the coordinate system. <IMAGE>

Abstract: In a procedure for optical spark-emission spectrometry in which a spark plasma of a sample is produced in a spark chamber and is evaluated by spectrum analysis using a spectral apparatus connected, in particular optically, to the spark chamber via a connection space, the connection space and the spark chamber having a protective gas continuously flowing through them during a spark process, a flushing pressure is built up in the gas system upstream of the spark chamber. The sudden release of this flushing pressure, for example, before the start of the subsequent spark process brings about a surge-like flow of the volume of flushing gas released in the spark chamber and, consequently, a complete removal of any burn-up residues or air components from the spark chamber. The gas flow can be interrrupted during the standby time. Equipment for carrying out the procedure comprises a spark chamber with an inlet for the flushing gas which can be sealed gastight by means of a shut-off device which can be opened suddenly. <IMAGE>
