Title: Method and device for monitoring and/or controlling the welding current in the high frequency resistance pressure welding of pipes with a straight bead
Inventor: KLIESCH WILFRIED DIPL ING
IPC: B23K13/02
Filed: 1983-08-17
Granted: 1987-01-08
Abstract: It is necessary to determine welding temperature as precisely as possible in order to properly control the high-frequency welding of longitudinal pipes. Changes in welding temperature are proportional to alterations in the welding current that flows through the edges of the skelp. Magnetic-field sensors can be used to directly and precisely determine alterations in the current and hence changes in the temperature. Voltages induced in the sensors can be processed into setting signals to correct the high-frequency welding generator and disruptions in the current used to generate signals to mark the site of failure on the pipe for subsequent rejection.
Patent DE-3370220-D1 (DE)
Title: Method of recording a digital information signal on a record carrier, record carrier provided with such an information signal, and read/write apparatus for such a record carrier
Inventor: HOFELT MARTIJN HECTOR HENDRIK
IPC: G11B5/58
Filed: 1983-09-16
Granted: 1987-04-16
Abstract: For a controlled positioning of a read element relative to a track to be read during the read-out of such a record carrier, low-frequency tracking signals may be recorded in the tracks. Instead of adding separate tracking signals to the information signal, these tracking signals are represented by the d.c. content of the information signal. During conversion of the information words of the information signal into channel words steps are therefore taken to provide two channel words whose d.c. content is equal but opposite for each information word. The choice between these two channel words is made depending on a control signal which depends on the desired tracking signal.

Title: Fuel injection device with main and pre-injection for internal-combustion engines
Inventor: SITTER ERHARD
IPC: F02M43/00
Filed: 1984-07-14
Granted: 1989-07-20
Abstract: A fuel injection apparatus with pilot injection and main injection in Diesel engines is proposed. A high-pressure injection pump delivers a main injection quantity to a main injection nozzle, while a hydraulic pilot injection auxiliary pump driven by the supply pressure of the high-pressure injection pump positively displaces a pilot injection quantity, via a piston, and delivers it to a pilot injection nozzle which is either separate or combined with the main injection nozzle. In the main injection area, a storage piston is separately provided, which without being mechanically connected to the pilot injection piston and without a pressure division is initially acted upon solely by the supply pressure of the high-pressure injection pump and only in the course of the pilot injection piston stroke is a line leading on to the storage piston opened up, at least indirectly, for the pumped fuel.
Patent DE-3479327-D1 (DE)
Title: Locks
Inventor: ROGERS JOHN
IPC: E05B47/00
Filed: 1984-11-29
Granted: 1989-09-14
Abstract: The lock has a bolt (2,3) which is shifted by handles on either side of the door, attached to a spindle (4). Movements of the bolt are controlled by two rotatable barrels (8) and (9) intersecting the profiled slots (10) and (11) in the bolt tail. In each barrel a pair of plungers (23) are sprung out into recesses in the surrounding lock body to block rotation of the barrel. Inward movement of the plungers to free the barrel is normally blocked by pairs of magnetic rotors (26A/26B, 26C/26D). To unblock the plungers a correctly coded magnetic key (Fig. 5) is inserted in the keyway (20) and the key and rotor magnets interact to turn the rotors into positions in which respective arcuate cut-outs (28) in the rotors align with the plungers (23). Turning the barrel now causes the plungers (23) to ride on inclined surfaces in the surrounding body thus pressing in the plungers and permitting rotation of the barrel. Barrel (8) is a "servant" barrel and barrel (9) is a "master". In Fig. 1 barrel (8) lies within a pocket (12) in the slot (10) to block throwing of the bolt. Turning it through 90 DEG  permits the bolt to be single-thrown (to 2 min ) whereupon it is blocked against further extension by barrel (9) in pocket (15) and blocked against retraction by barrel (8) in pocket (14) when (8) is rotated back to its locked position. Turning barrel (9) through 90 DEG  now permits the bolt to be double-thrown (to 2 min ) whereupon it is blocked against retraction by barrel (9) in pocket (17) when the latter is rotated back to its locked position. Retraction of the bolt involves the reverse sequence.

Through provision of an intermediate carrier, the upper disc is fixed to the upper rocker lever in a manner that it can pivot around a horizontal axis which is at right angles to the rocker lever shaft. Therefore the upper disc can be tilted in the respective direction of transport.
