Inventor: BUDAI PETER
IPC: B23K9/12
Filed: 1987-02-16
Abstract: A method of controlling a welding operation during arc welding between a fusible electrode and a workpiece, wherein the welding operation alternates between arc periods and short-circuiting periods, includes the steps of sensing a first parameter of the welding operation, for example the arc voltage between the electrode and the workpiece, generating a first signal representative of the first parameter, sensing a second parameter of the welding operation, generating a second signal representative of the second parameter, filtering the second signal to provide a filtered signal, generating a desired value signal based upon the filtered signal and controlling the welding operation based upon the difference between the desired value signal and the first signal. According to the method of the present invention, any changes in the second signal that occur at a frequency outside a predetermined frequency range, which includes a desired short-circuiting frequency of the welding operation, are attenuated such that the desired value signal is less affected by these changes than by changes occurring at a frequency within the predetermined frequency range. An apparatus for carrying out the method includes a band-pass filter having a pass band including the desired short-circuiting frequency.

Title: Laser radiation frequency nonlinear tuning device
Inventor: MICHAILOVAS ANDREJUS
IPC: H01S3/10
Filed: 1996-12-20
Abstract: The invention applies to the field of lasers, namely to a frequency converter tuned by laser radiation. The task of the invention is to create a less expensive and more effective converter. The point of the tasks solution is as follows: in the proposed method, according to the invention converter, the function of the two nonlinear parametrical interaction crystals is realised by one nonlinear (parametrical generation) crystal, through which, as according to the proposed placement of the converter's nodes, parametrical and accumulating radiation is conducted twice in turn, and the conversion effectiveness is increased by an additional mirror returning laser radiation and parametrical radiation into the nonlinear (difference frequency generation) crystal, this way relatively increasing it's length.

Title: Equipment for using excess steam
Inventor: KAPPEL JOHANNES DIPL ING DR TE
IPC: D21F5/02
Filed: 1985-07-03
Granted: 1987-10-27
Abstract: The invention relates to equipment for using excess steam in the steam/condensate system of drying or heating devices combined into individual groups with the same pressure level for paper or coating machines, the individual groups being heated successively with steam of respectively lower pressure level. The condensate/steam mixture led away from a group is led to a separator for separation into the vapour phase and the liquid phase, the steam being fed to the respectively following group at lower pressure. The condensate is fed into the boiler house, a degasser or a condensate conditioning unit, and it is possible for the excess steam occurring in a group to be discharged via controlled valves, preferably with lines branching off the steam lines. In order to use the excess steam, the invention provides for the separator 5 which accommodates the condensate occurring in the individual groups to be connected to a collecting container 23, from which the condensate is fed into the boiler house or to the degasser 27, and for the excess steam, accumulating at above a pressure of 1 bar, from preferably all the groups to be fed by a distribution device 28 to the collecting container 23 below the water level in order to precipitate the excess steam and heat up the condensate. <IMAGE>

Title: Inertia-sensor-assisted measuring system for manipulators
IPC: G05B19/423
Filed: 1989-08-31

Abstract: The measuring system according to the invention serves for the dynamic measurement of the position coordinates and spatial-orientation positions of moving manipulators, in particular multi-axis industrial robots having as many degrees of freedom as desired, by means of inertia sensors 1. The inertia sensors 1, by means of rigid connecting elements 2, 3, together with measuring systems for determining position and orientation in the immediate vicinity of a spatial reference point 4, 5, 6, are combined to form a measuring head, fastened to the manipulator, in such a way that, by algebraic combination, coordinate transformation and integration of the processed sensor signals by suitable, preferably digital, arithmetic units, the time characteristic of position coordinates and spatial-orientation positions of the measuring head in the reference space is calculated as a measurable output quantity, for example for the purpose of investigating accuracy characteristics of the manipulator. <IMAGE>
