Title: Method for adjusting a laser resonator, and a laser having a device for adjusting a laser resonator
Inventor: BEYER ECKHARD DR ING
IPC: H01S3/139
Filed: 1988-03-09
Abstract: A method for adjusting a laser resonator, in the case of which at least one resonator mirror is tilted transversely with respect to the axis of the active material until the laser power is maximised. In order to be able to achieve optimum adjustment of the laser resonator permanently as well, the procedure is that the tilting of the mirror is carried out by a motor and the laser power is at the same time measured continuously over a defined tilting angle range which includes the maximum value, the measured power values being stored by a computer which, after completion of the power measurement in the tilting angle range, allows the mirror to be adjusted by the motor to the tilting angle position corresponding to the maximum value.

Title: Shearer loader which is equipped with an additional drum rotatably mounted on a pivotable supporting arm and arranged above the face conveyor
Inventor: WEBER KARL-HEINZ DIPL ING
IPC: E21C27/02
Filed: 1988-05-14
Abstract: The additional drum of a shearer loader, if it is arranged in a vertically adjustable manner on a supporting arm in front of the machine body, is put into its working position by the machine operator by means of a pivoting device. The machine operator is to be relieved of this activity, namely the disengaging and engaging of the pivoting device, but also the decision as to whether the use of the additional drum is necessary with regard to the coarseness of the excavated material conveyed up to the machine. It is proposed to provide a radiation source (22) which is located in front of the machine body, transmits in a pulsating manner and is directed towards the excavated material reaching the machine body. By means of a receiver (21) which is adjacent to the radiation source (22) and triggers an output signal if a fixed signal transit time is not reached by the backward radiation, the pivoting device (15) of the supporting arm (12) of the additional drum (8) is actuated. The additional drum (8) is thereupon lowered down to a plane determined by the top edge of the portal opening of the machine frame (7), catches all parts of the excavated material projecting up above this plane and crushes them. <IMAGE>

Title: Method and apparatus for disposing of spray cans containing liquid propellants
Inventor: POHL KURT M DR ING
IPC: B09B3/00
Filed: 1988-11-05
Abstract: A method for disposing of spray cans containing liquid propellants is proposed, in which the spray cans are introduced into a pressure container (10) and are there made untight by pressurisation, after which the escaping propellant is then guided out of the pressure container (10) for disposal. The pressurisation preferably takes place with water, no separation of the propellants from an inert gas, such as air, being necessary any longer in the case of a pressure container (10) filled completely with water. In this method, no mechanical tearing devices are necessary for destroying the spray cans so that the method can be carried out economically, safely and with low maintenance. <IMAGE>

Title: Method for the refractometric measurement and stabilisation of wavelength or frequency
IPC: G01N21/45
Filed: 1989-04-08
Abstract: A method is described for the stabilisation of the frequency or of the wavelength of a diode laser for interferometric length measurement. The optical length of the air chamber of a stable external reference each having at least one vacuum chamber and air chamber and each an associated interferometer whose mechanical length and frequency (wavelength in vacuo) is connected, for a defined working point, to the metre definition of 1983, is measured during the turn-on period by means of frequency variation and in comparison with the vacuum chamber, by which means the instantaneous refractive index of the air is determined as a correction value and is stored. By means of switching over simultaneously, the wavelength is stabilised by controlling the frequency relative to this measured value. In an analogous way, the frequency can be stabilised and the variation of the refractive index in the air chamber can be measured and used for correction. The refractometer used as reference is simple, the process sequence of the method is programmed, so that the relative cost for a length measuring interferometer of high stability is small. <IMAGE>
