Title: One-piece rotor shafts for turbines and generators - have weld-metal deposited on rotating steel core to give uniform structure
Inventor: BRANDI HERMANN-TH DR MONT DR
IPC: F16C3/00
Filed: 1973-04-19
Abstract: Large shafts with a structure free from inclusions, pipe, segregation and cracks, are made by the continuous deposition of weld-metal. Uniform mechanical properties are obtd. and zone with special properties (e.g. high magnetic induction) can be produced, without the necessity for hot-working or hardening and tempering. A rotating core (which can itself be built-up by welding) is mounted on a base plate of a machine possessing >=1 welding-head continuously fed by wire and powder. The welding head(s) can be mounted on a trolley so that they can travel the length of the shaft. The wire is connected to a welding generator. In this way a spiral of metal can be deposited on the core in any desired form, e.g. overlapping beads, and layers built up of appropriate compsn. A shaft was manufactured in this way with compsn. (all%) 0.08C, 0.34 Si, 1.82 Mn, 1.51 Ni, 0.63 Mo, 0.31 Cr, 0.08 Cu, rest Fe. It was free of porosity and other defects, with a homogeneous structure, uniform chemical compsn. and uniform mechanical properties in the axial, tangential and radial directions. A variety of alloy steels can be used with layers of different compsn. and the shafts can be heated and/or cooled during the process.

Title: Method of boring holes in anchor studs - uses pivoting blade on drill bit to cut conical section passage
Inventor: KESSLER JUERGEN
IPC: B23B51/00
Filed: 1973-09-25
Abstract: Boring of location holes intended for wall fixing devices of the type comprising a central screw and expanding sleeve. The holes have a parallel sided length with a central conical section. The boring tools are arranged such that after the start of the straight hole has been bored, pressure against a spring causes a second cutting edge, mounted within the first, to pivot outwards to cut the conical section. This lateral movement can be caused either by pivoting or by a system of helical slides which rotate to give progressive lateral movements. Other variants include the second cutting edge pushed diagonally through a slot in the straight sided drill.

Title: Large stroke drive for earthing cct. breaker - has electromagnetically actuated switching plunger forming part of linear motor
Inventor: BUROW NORBERT
IPC: H02B13/075
Filed: 1974-04-09
Abstract: The switching drive for a circuit breaker with a large stroke, especially for an earthing circuit breaker, uses an electromagnetically movable switching plunger which forms one part of relatively movable parts of a linear motor. With the linear motor out of operation the plunger can be moved in one of its switching positions by a spring, while being held in the other switching position by a force of a magnet. This arrangement is intended particularly for applications, in which pneumatic or electric motor drives cannot be used for prodiving a large switching stroke, especially for an earthing switch in an energy waveguide from a transmitter to an antenna. The holding magnet provides closing of the breaker whenever the current should fail.

Title: Mosaic wire printing head used with magnets - has printing wires moving against spring action when plunger-type armature is energised
Inventor: STAHL HORST
IPC: B41J2/26
Filed: 1974-07-30
Abstract: The part of each printing wire which is to be fixed in the plunger-type armature is sintered into place in the ferromagnetic sinter material of the armature. Various forms of connection are possible, for example the wire (2) can extend through the armature (5) or terminate within it. Alternatively, the end of the wire is bent to facilitate anchoring it in place in the armature. An advantage of these designs is that the armature-wire combination can be effected in a single working process; namely during the sintering stage for the armature. The result is a simply-produced and effective coupling between the component parts.

Title: Multi spindle milling machine - has inclinable clamping plates for workpieces to milling spindle axis
Inventor: MAAS JOHANN
IPC: B23C1/08
Filed: 1974-12-12
Abstract: The multi-spindle numerically controlled four axes milling machine has a table which is controllable in the X and Y axes. A milling spindle is controllable in the Z axis, and an inclinable clamping device for the workpiece is connected to the table, and numerically controlled in its angular position to the Z axis. Each workpiece is located on a clamping plate connected to the table, each plate being either similarly or counter-couplable in their angular movements. This arrangement obviates the need for the milling spindles to be well spaced. The spindles can have a single motor driving through a bevel gear from a transverse drive shaft or one motor for each pair of spindle.

Title: Amplifying control cct for chrominance channel in TV receiver - produces, at most negligible phase rotation of signal
Inventor: CAMPIONI ARMANDO
IPC: H04N9/68
Filed: 1974-12-18
Abstract: The chrominance channel amplifying control circuit has at least one colour information phase modulating a sub-carrier. A suppression circuit within the main circuit contains a potentiometer and within its impedance contains at least one component which can be regulated by d.c. voltage. This component (9) is regulated as basically a variable resistance when receiving the sub-carrier. The circuit is so designed that changes in the level of the chrominance channel results at most, in negligible phase rotation of the chrominance signal. The diode (9) resistance can be varied within a range of between (10 Ohms) and (2.5Kohms) depending upon the d.c. flowing through it, which depends upon the settings of potentiometers (15, 17, 18).
