Patent DE-3614310-A1 (DE)
Inventor: WOHLLEBEN WOLFGANG DR
IPC: C12N15/00
Filed: 1986-04-28
Abstract: Mutants can be obtained in a very simple fashion by isolating the entire DNA from the strain to be mutated, cleaving this DNA into small fragments and integrating it into a temperature-sensitive plasmid using a further selection marker, transforming the resulting hybrid plasmid population into the original strain, selecting the transformants by selection for the marker, eliminating the hybrid plasmids by increasing the temperature above the threshold value of the temperature-sensitive plasmid, and selecting the mutants by reselection for the marker. Since the mutated gene is marked in this manner, it can be isolated easily and the unmutated gene can be isolated from a gene bank of the wild type by hybridisation.

Title: Circuit arrangement for telecommunications switching systems with direct dialling
Inventor: PIEPENBRINK WERNER
IPC: H04Q3/72
Filed: 1986-12-22
Abstract: The circuit arrangement for identifying each calling subscriber according to the main patent ... (application P 3542405.2-31), in which the caller-end functional unit is divided into two sub-units, i.e. a line finder unit provided for the line finders and a group selector unit provided for the pulse group selectors is modified here in such a way that the step of a line finder is not transmitted from the line finder unit AS-E via the meter wire z-A to the group selector unit GW-E each time that it is re-adjusted, but rather a DC signal is obtained from the polling signal arriving in the group selector unit by means of a DC transmission circuit GS, which signal is transmitted via the meter wire z-A to the line finder unit where it is received by a corresponding receive circuit GE. A transmission circuit for AC voltages WS in the line finder unit transmits the audio-frequency AC voltages which contain the telephone numbers only when this signal arrives. The latter are fed in the group selector unit via a corresponding receive circuit WE into one winding OLÜ of the local line transformer. The group selector unit also has an audio receiver TE and the line finder unit has a receiver for meter pulses ZE. The dial pulses are also transmitted as DC signals from the group selector unit to the line finder unit.

Patent DE-3716588-A1 (DE)
Inventor: PULM TONI DIPL ING
IPC: F16F15/12
Filed: 1987-05-18
Abstract: Torsional vibration dampers have a receptacle (1), which can be flanged onto a shaft, and a vibration-damping flywheel ring (2), which is elastically coupled to the circumference of the receptacle (1) via at least three rubber webs (3). At high speeds, there is a risk that the flywheel ring (2) will be displaced eccentrically with respect to the receptacle (1), as a result of a small unbalance. To prevent this radial displacement, at least three elastic spacers (5) are arranged in the gap (4) between the receptacle (1) and the flywheel ring (2), at equal intervals around the circumference of the receptacle (1), leaving free a narrow residual gap. Torsional vibration dampers of this type are intended particularly for motor vehicle transmissions. In order to dimension this residual gap precisely, and to achieve smooth running in the event of radial movements of the flywheel ring with respect to the receptacle, the spacers (5) are vulcanised onto the inner wall of the flywheel ring (2) and pocket-like cut-outs are formed in the spacers (5), into which there can be inserted flat shims (6) of material with a stable shape, such that the spacers (5) are extended in a smooth manner toward the receptacle (1), such that the residual gap is less than 0.2 mm. <IMAGE>

Title: Process and device for spraying the edges of rectilinearly limited sheet-like workpieces
Inventor: STUEMPFIG FRITZ
IPC: B05B13/02
Filed: 1987-05-30
Abstract: Efforts to automate manual work for edge treatment has apparently hitherto failed in that the precise automatic guidance of spray guns along edges of variable length and disposed in various directions was regarded as too high a technical outlay. This obstacle is overcome in that the workpiece is conveyed by four continuous conveyors which convey at right angles to one another and are connected to one another by three transverse-conveying devices, sequentially with each of its four edges past one of four spray gun devices which are arranged in each case adjacent to the continuous conveyors and are switched on and off by means of a tracer control operated by the workpiece.

Title: Circuit arrangement for error detection in coded digital signals
Inventor: MEYER GERHARD DIPL ING
IPC: H04L1/24
Filed: 1987-09-25
Abstract: A circuit arrangement is known for error detection in coded digital signals by means of checking the running digital sum with the aid of a differential amplifier connected as an integrator. A load impedance is situated in each case in the output circuit of the differential amplifier. The base-emitter diodes of transistors are used as triggers. This circuit arrangement is, however, not suitable for all signals which can be monitored by checking the RDS. The circuit arrangement proposed by the invention can be used to process all digital signals which can be monitored by checking the running digital sum. For this purpose, an integral controller is connected in parallel with each load impedance. The invention is applied, for example, in code protocol violation checking of CMI-coded data signals.

Patent DE-3800291-A1 (DE)
Title: Electrical safety circuit
Inventor: LAUERER FRIEDRICH DIPL ING
IPC: H02H5/08
Filed: 1988-01-08
Abstract: The described electrical safety circuit operates in a very simple manner and is particularly suitable for defence against hazards. A relay is used as the disconnection device and draws the voltage required for this connection from a voltage divider. If a disconnection is intended to be carried out as a result of a defined operating state discrepancy, the relay coil receives the voltage necessary for this purpose from either one pole or the other of the power supply source, that is to say the disconnection is carried out irrespective of the current behaviour or of the plug position. The disconnection can be triggered by a probe which responds to moisture, liquid, and temperature or other physical or chemical states. In particular, the circuit also operates in the case of an interruption in the neutral conductor, in the case of a high network loop resistance, and in the case of two-phase alternating-current operation. The safety circuit can be used, for example, in a hair dryer and prevents a lethal electrical accident if the appliance is dropped into a bathtub which is filled with water.

Title: Circuit arrangement for the compensation of attenuation losses
Inventor: PERY ANTOINE
IPC: H04N9/77
Filed: 1988-06-10
Abstract: In a circuit arrangement which delivers an output signal undelayed with respect to the input signal via a direct path and an output signal delayed with the aid of a delay element via a delaying path, the voltage loss caused by the delay element must be compensated for. This is carried out by means of manual compensation. By means of the invention, the output level is automatically compensated. For this purpose, the output signals are each connected to a multiplier at both inputs. The outputs of the multipliers are connected to a differencing circuit whose output voltage adjusts the gain in one of the two paths in such a manner that the two are equally large. Automatic amplitude compensation of a PAL decoder or of a comb filter. <IMAGE>
