Patent DE-3214113-A1 (DE)
Title: Blind riveting device for the automatic setting of blind rivets
Inventor: KAEHNY PETER
IPC: B21J15/34
Filed: 1982-04-16
Abstract: The invention aims at the design of a blind riveting device, as known for manual operation, for the automatic setting of blind rivets. This technical problem is solved by the fact that a riveting unit is arranged at both ends in a housing and that the housing is mounted to rotate centrally about an axis perpendicular to its longitudinal axis. A riveting unit can thereby be moved from a position opposite a charging station with rivet feed into a working position opposite a work support and vice versa. During the movement into the working position, the pulling device for the rivet mandrel for the formation of the rivet head and the subsequent tearing off of the mandrel can be coupled to a motion drive for this purpose. The torn-off rivet mandrel is pressed towards a discharge channel in the riveting housing in the charging position by a first stroke of a ram. In a second stroke, the same ram presses another rivet between the clamping jaws of the riveting unit. The new mandrel pushes the torn-off mandrel into the discharge channel. <IMAGE>

Patent DE-3219213-A1 (DE)
Title: Circuit arrangement for optimum characteristic shaping for special electrodes
Inventor: HABELER HEINZ DIPL ING
IPC: B23K9/06
Filed: 1982-05-21
Abstract: The circuit arrangement is provided for the energising machine of a brushless rotating welding machine, the transformer having a second secondary winding whose output is connected to a bridge rectifier from which a DC voltage terminal is connected to the identically polarised DC voltage terminal of the bridge rectifier connected to the first secondary winding, and the second DC voltage terminal is connected to the identically polarised welding current socket. The connection of the field winding to the second DC voltage terminal of the other bridge rectifier is connected to the second welding current socket. Furthermore, the voltage on the second secondary winding of the transformer is also higher than that on the first secondary winding. This circuit results in an increase in the continuous short-circuit current. This is advantageous since in this way optimum welding properties are now provided in the case of cellulose electrodes as well.

Patent DE-3227170-A1 (DE)
Title: Method for signalling
Inventor: STURM CARL HEINZ DR
IPC: H05B41/232
Filed: 1982-07-21
Abstract: In order to signal specific processes, instructions or information items via an illumination system containing fluorescent lamps (10, 12, 14) in buildings or underground, the supply current for the illumination system is reduced or switched-off in a specific rhythm, the switching-off or reduction in the supply current taking place during the signalling pulses at a frequency, preferably of 5-15 Hz, which takes into account the flicker-sensitivity of the eye. In consequence, the life of the fluorescent lamps is considerably increased. The switching-off or reduction in the supply voltage takes place via a load relay (26) which is driven by a pulse transmitter (28). <IMAGE>

Title: Thermometer cabin for measuring the air temperature
Inventor: HORMANN KLAUS PROF DR
IPC: G01W1/00
Filed: 1982-09-11
Abstract: During climatological-meteorological measurements, in order to avoid the air flowing over surfaces which are subjected to direct solar radiation immediately before flowing into a thermometer cabin, and thus being heated, and in order to reduce the weight and production costs of the cabin, the ventilation openings are restricted to the bottom and to the side of the cabin facing the pole and the walls are constructed of material of poor thermal conductivity and low weight, for example of polystyrene resin foam. In order to improve the utilisation of horizontal air flows for ventilation of the cabin, air guide plates can be fitted under the cabin, the surface area of the latter producing shade possibly being enlarged by a collar fitted to the lower edge of the cabin, which air guide plates guide horizontal air flows from below into the cabin, especially those which are not directed onto the single side of the cabin which is provided with ventilation openings. In order to minimise the radiation absorption of the cabin, the outside is normally provided with a metallic surface (e.g. a metal foil covering) which reflects like a mirror.

Patent DE-3322542-A1 (DE)
Title: Process and apparatus for the low pressure casting of articles from metals
Inventor: GROSS GERD DR
IPC: B22D18/04
Filed: 1983-06-23
Abstract: The metals are especially special steels. While the yield in low pressure casting is normally satisfactorily large only when very large castings, for example weighing 10 tons, are cast, the invention aims at raising the yield markedly, especially for small articles. This essentially happens according to the proposal of the invention in that a metal sleeve is used as a lost riser, without the need to provide the mould inlet with a closure or the outlet with risers. At the same time the expensive graphite moulds can be avoided. Likewise, the otherwise necessary ceramic casting pipes are omitted. The quality of the castings is characterized, with high yield, by a smooth surface and by freedom from voids.
Patent DE-3323590-A1 (DE)
Title: Display device for flow meters
Inventor: PIENTA LOTHAR ING GRAD
IPC: G01F1/22
Filed: 1983-06-30
Abstract: The invention relates to a display device for flow meters, each of which operates with a float. The latter is provided with a permanent magnet by means of which light-emitting diodes arranged on the flow meter can be excited. The light-emitting diodes have two PN junctions, i.e. a luminous green junction and a luminous red junction, which can be connected individually by means of a changeover switch upstream of each light-emitting diode. It is achieved in this way that specific prescribed light-emitting diodes are luminous in green when excited, while the other light-emitting diodes are luminous in red when excited. As a result, it is possible, by appropriate selection of the colours of the light-emitting diodes, to set in advance minimum and maximum values and permissible and impermissible regions for the position of the float on the display device.

Title: Device for the controllable operation of unbalanced drives with three-phase motors
Inventor: BRAUN HORST DIPL ING
IPC: H02P23/06
Filed: 1983-10-20
Abstract: Device for the controllable operation, especially for the speed adjustment and braking of unbalanced drives with three-phase motors by switching the power supply on and off in a pulsed manner, by means of electronic switching means. A disadvantage of this device is that the oscillating magnets do not correspond to the values which are achieved in the case of motor-driven unbalanced drives with respect to their adjustment and retention accuracy and the shortening of the deceleration time. This advantage can be achieved in the case of oscillating magnets by providing a central signal distribution and locking stage (4) which is supplied with synchronisation pulses (6) from the network (L1-L3) and acts on the electronic switching means (9) via oscillator stages (5), and which is connected on the input side to a start-stop switching and locking unit (10), a starting timer (7), a controllable multivibrator (1) and a braking DC current phase-gating control stage (12) controlled by means of a timer (11), and by it being possible to bridge over two phases of the power supply during the braking process using electronic switching means (13). <IMAGE>
