Title: Pebble bed reactor reflector channels - have lining sleeves esp. of graphite to minimise cooling gas leakages
Inventor: ELTER CLAUS DR ING
IPC: G21C1/07
Filed: 1980-12-23
Abstract: Side reflector for a nuclear reactor, esp. gas-cooled pebble bed reactor, is composed of graphite blocks and has vertical ducts through it for fixed and moving components such as absorber rods. These ducts are lined with sleeves connected together by push-in type connection (spigot and socket connections). Pref. there is one sleeve per graphite block. The start of a sleeve may have a widened dia. and the end of the sleeve a reduced dia. More specifically there is a taper at the start of the sleeve. The end of a sleeve may extend into the neighbouring graphite block. Pref. the sleeves are of graphite. Used partic. for a gas-cooled reactor of the pebble bed type. Distortions due to thermal and other stresses during the life of a reactor can result in gaps appearing between adjacent blocks, with the consequent disadvantage that initially designed cooling passages, such as ducts for absorber rods, are affected in their function by unintentional ingress of hot gas from the core or escape of gas into adjacent zones; the effect of this is to detract from the proper performance of the reflector cooling system as designed. By lining the ducts with sleeves which mate one into the other, assurance is provided that the cooling system will be maintained and leaks will be minimal.

Patent DE-3103443-A1 (DE)
Title: Metal such as, for example, copper, aluminium, zinc, magnesium etc, or a metal alloy, fabricated in disc, spiral or other form, which can be placed in the mouth to cure infectious diseases
Inventor: PICKEL HANS
IPC: A61K33/34
Filed: 1981-02-02
Abstract: Metal such as, for example, copper, aluminium, zinc, magnesium etc, or a metal alloy, fabricated in disc, spiral or other form, which can be placed in the mouth to cure infectious diseases and to eliminate possible deficiency states. Copper bracelets which have caused the disappearance of rheumatism have previously been used. If, instead of wearing a copper bracelet, a piece of metallic copper such as a copper disc is placed in the mouth for about half an hour/day, the same effect is achieved. A copper disc is additionally able more or less to normalise hair which is going grey or has recently become grey. It is probable that the copper disc will eliminate a chronic infection of the scalp or/and possible copper deficiency. Pieces of metallic aluminium such as, for example, aluminium discs cure some viral infectious diseases when they are placed in the mouth, especially at night, until the infection, such as, for example, catarrh, has disappeared. If, for example, catarrh has developed and an aluminium disc is placed in the mouth right in the first few minutes, experience has shown that the catarrh disappears in less than half an hour.
