Title: Clay impregnation with metallic ions - to produce low melting binders in the clay
IPC: C04B33/13
Filed: 1973-10-03
Abstract: In a method of treating clay or any clay based ceramic compsn. metallic ions whic form oxides at the firing temp. of the clay are distributed throughout the clay by mixing the dry clay with solid crystals of a cpd. esp. a salt of the metal, then contacting the mixt. with a liq. phase which may dissolve the ions at least partly and thoroughly mixing, or which may be the crystals in the molten state, to diffuse the ions into the clay. Clay so treated is calcined, moulded and fixed. Preferred ions are alkali(ne earth) and transition metal ions. The ions are chosen so that they form low wetting silicates which produce a low wetting ceramic bond with the clay particles, hence the clay mouldings can be fixed at a comparatively low temp. and have the same or better mechanical properties than those fixed at normal firing temps.

Title: Neutron detectors in nuclear reactor with liquid moderator - detector housings being made of material with low neutron moderating power
Inventor: NEISSEL JOHN PAUL
IPC: G21C17/10
Filed: 1976-07-30
Abstract: The detector system comprises longitudinal housings each contg. a number of detectors. The housings are made from a material having a low neutron-moderating ability and a low neutron capture cross-section (pref. Zr,Nb,Al,Mo,Ti,Cr or their alloys). The neutron detection are fixed at different levels in channels; whilst the neutron detector can be lowered and hoisted along the channel to record the neutron flux along the whole height of the reactor. The detector housing is dimensioned in such a manner that it nearly completely displaces the liq. moderator from the space between the nuclear fuel elements and the neutron detectors. Thus there is practically no neutron moderation in this space and the detectors monitor the neutron flux as it is in the vicinity of the nuclear fuel elements.

Title: Doped silicon monocrystals drawn from a melt - where pure silicon is melted in drawing cubicle before adding dopant
IPC: C30B15/04
Filed: 1976-09-24
Abstract: The novelty is that the semiconductor is melted in the drawing crucible, and then the dopant is added via a feed tube which is partially immersed in the melt. The feed tube pref. extends out of the drawing chamber and is connected via a flexible tube to a reservoir contg. the dopant. The pref. semiconductor is silicon, and the pref. dopants Sb or As. The feed tube pref. has an enlarged outlet end dipped 1-5 mm into the melt. If Sb is added at the start of melting, its low m.pt. w.r.t. Si results in the deposition of Sb on the chamber wall and inaccurate doping of the Si. This is now avoided.
