Title: Socket with earthing contact
Inventor: LEE SOO IN
IPC: H01R13/453
Filed: 1983-03-11
Abstract: The socket with earthing contact is provided with a safety device in order to close the contact holes when the socket is not in use. The safety device has a protective vane, a hollow cylinder, a spring and a spring protective device. This safety device is plugged onto a pin which is integrally formed on the plug body. This plug body furthermore has a protective device seat into which the protective vane is fitted. When the socket is not in use, the protective vane is located in a rotationally-fixed manner in the protective seat and, in consequence, can release the contact holes only when, at the same time, a pressure is exerted on the two ends of the protective vane into these contact holes, in the same way as during insertion of the two contacts of a plug. As a result of this uniform pressure effect, the protective vane is pressed out of the protective seat and is rotated on the socket body by means of guide surfaces.

Patent DE-3318042-A1 (DE)
Title: Universal measuring instruments with a high-resolution display for workshop use
Inventor: SELBACH GERD PROF DIPL ING
IPC: G01B11/00
Filed: 1983-05-18
Abstract: Through the use of a measuring signal which arrives at an acute angle by comparison with a reference signal arriving at right angles on a reference surface, the measuring instrument permits accuracies of better than 0.005 mm to be maintained with the naked eye. In this arrangement, the signals are intersection tracks of rotating laser beams with the reference surface, it being possible for the intersection tracks either to be one-sidedly linearised, or else to be modulated in a heterodyne fashion or unmodulated. The measurement distance can be selected within wide limits by variable focusing of the beam. The instrument serves the purpose of continuous comparison of a workpiece surface to be machined with the machine slideway, as well as vibration measurement on workpiece surfaces with the aid of a stroboscope. The influence of drift and turbulence are continuously detected by tapping the measurement signal and fixing it at a point fixed on the machine. This point is situated in the region of the maximum rate of angular variation because of the extreme constriction of the initial focus arising here. Tapping the beam path and using an appropriate beam expander allows path levelling.

Patent DE-3324805-A1 (DE)
Title: Device for the prevention of pressure fluctuations in combustion chambers
Inventor: GLAS PETER ROBERT DIPL ING
IPC: F23M20/00
Filed: 1983-07-09
Abstract: Pressure waves start from the burners or their flames and can cause disturbances and damage in the combustion chambers. At the same time, these pressure waves also run in the opposite direction to flow. While pulsating combustion processes due to the pressure waves can be prevented for a certain frequency range by lateral cross-section widenings, this has not yet been found to be possible over the whole operating range of a burner. The invention makes possible such a vibration damping, without influencing the combustion chamber, by the provision, along the gas duct path to the burner, of cavities like Helmholtz resonators which are of different sizes and thus damp a frequency range in which the burner may be operated.
Patent DE-3334720-A1 (DE)
Title: Device for the control of a plurality of drive units which can be switched on and off for a drive engine
IPC: F02D17/02
Filed: 1983-09-26
Abstract: In the case of a device for controlling a plurality of drive units which can be switched on and off for a drive engine in a motor vehicle the stationary drive torque is used as criterion, which corresponds to a driving condition essentially free of deceleration or acceleration. When the stationary drive torque is greater than the upper limit of a comparison range, a signal is generated which can be used for switching on the drive units. A signal which can be used for switching off the drive units is correspondingly generated when the stationary drive torque is less than the lower limit of the comparison range.

Title: Device for probing boreholes
Inventor: KLAMMER GERHARD DIPL ING
IPC: E21B47/00
Filed: 1984-07-21
Abstract: A device is provided for probing boreholes, in which the standpipe is to be connected in a force-closed fashion to the borehole wall and has a stop which interacts with locking members assigned to the probe rod in such a way that after the probe rod has been guided through the standpipe and introduced into the borehole it is fixed therein. The standpipe can then directly be rotated and also be moved slightly in the longitudinal direction, but cannot be drawn out of the borehole. By cancelling the effect of the stop and of the locking members, it is, however, then possible after termination of the measurements to recover at least the probe rod, but also usually the standpipe, so that it can be multiply used. <IMAGE>

Title: Discharge valve on fire extinguishers
Inventor: LITSCH PETER
IPC: A62C37/42
Filed: 1984-12-06
Abstract: The discharge valve flanged onto a pressurised container holding fire extinguishing means comprises a housing and a discharge element, the interior space of both of which is separated from that of the container by a membrane which bears, on the one hand, on a bearing site of the interior space and, on the other hand, on a support plate. The support plate bears on a cam shaft which is designed so as to be adjustable and as a result effects the positional change of the plate, and is underpinned by adjustment means in such a way that, if required, it can be moved from its original position, whereupon the membrane, which is no longer supported, bursts as a result of the pressure exerted thereon. In order to monitor the valve for correct functioning and to take counter measures in the event of a fault, one of the cams of the cam shaft, after unlatching the support plate and when a predetermined rotational angle of the cam shaft has been exceeded, actuates a microswitch which signals correct functioning or, alternatively, via an external control unit makes available the fire extinguishing means of a standby container.
Patent DE-3502638-A1 (DE)
Inventor: SCHMITT ROBERT DIPL ING
IPC: G01R15/06
Filed: 1985-01-26
Abstract: In a method for the elimination of the d.c. voltage components of a capacitive a.c. voltage divider whose a.c. measuring voltage which may include a d.c. voltage component, is fed to a measurement transformer, the task is to be solved to remove as quickly as possible the d.c. voltage component of the a.c. measuring voltage also to the greatest extent possible without falsification of the reproduction of the middle or high voltage to be measured. This is achieved in that the a.c. measuring voltage (UM) is fed to a measuring amplifier (14) by way of two parallel lines (L1, L2) via a d.c. voltage blocking element (6). The a.c. measuring voltage (UM) is thereby fed directly by way of one line (L1) and the d.c. voltage component (UG) of the a.c. measuring voltage (UM) is determined in the other line (L2) in that the a.c. measuring voltage (UM) is subdivided into such small time sections (t) that an equal number of time sections is coordinated per cycle (T) or half cycle (T/2) and the a.c. measuring voltage is continuously integrated over a period (T) at the frequency (Tf) of the time sections (t). The thus-determined respective d.c. voltage value (UG) is fed to the measuring amplifier (14) in phase opposition to the original value and by way of the latter to the measurement transformer (16) (FIG. 1).
