Title: Absorber rod drive for pebble bed reactor - having two motors and combined gear system to change ratio of rotational to linear motion
Inventor: MUELLER-FRANK ULRICH DR ING
IPC: G21C7/14
Filed: 1977-03-17
Abstract: A drive for a rotatable and/or axially movable absorber rod for a nuclear reactor comprises a gear assembly (pref not self-locking) can be driven optionally by a first and/or a second drive motor. The output side of the gear assembly acts in the longitudinal direction of the absorber rod, esp. with chains, and the entire gear is rotatable about the longitudinal axis of the rod by means of the second motor. To enable the helically threaded rod to penetrate into the reactor core, it is rotated at a speed higher than that corresponding to the pitch of the threads as it advances. To withdraw it, however, the rotational speed is dropped. By using two separate motors with this arrangement, different combinations of linear speed and rotational speed can be obtained with a single gear unit. If the power supply to the motor fails, the entire rod drops under gravity into the core to shut the reactor down.

Title: Copper or aluminium wire drawn from rods - which are made by splitting a slab longitudinally to form several rods simultaneously
Inventor: PFEIFFER HANS ING GRAD
IPC: B21C37/04
Filed: 1977-05-04
Abstract: Rod is made, esp. of soft metals, e.g. electrolytic Cu or Al, where the rod is then used as the starting material for drawing wire with very small dia. A continuous material (a), which has a slab-, elongated- or an oval- cross-section, is fed through roll grooves so the slab is split into several longitudinal strands or rods which are rolled to the desired dia. Continuous round rod of large dia. may be squeeze-rolled to form material(ae with an oval cross-section which is then split into the strands. Material(a) may first be rolled so notches are formed in the cross-section; and subsequent rolling then splits the material into several strands. The object is to increase productivity in the mfr. of small dia. wire, where e.g. an oval slab can be converted into several strands each 4.5 mm. dia.; these strands or rods are then used for drawing. The result is a redn. in the total number of rolling and/or drawing passes required to mfr. the wire.
