Title: Spherical graphite and fuel elements distinguished in analysis - by large systematic error associated with graphite only elements
Inventor: DAOUD HASSAN DIPL PHYS
IPC: G21C17/06
Filed: 1975-07-12
Abstract: The neutron interaction properties are measured as they are successively passed through zones of a measuring reactor in which neutron-absorbing, neutron-scattering and fissile substances each possess a maximum influence on the reactivity of the measuring reactor. The power variations occurring as the spherical elements pass through the reactor provide characteristic curves. These evaluated by an analysis programme to give the composition of the elements. The apparent difference between the graphite content of a graphite element as given by this analysis programme and the actual graphite content in the element is utilised for distinguishing between graphite elements and fuel elements which possess approximately the same graphite content as the graphite elements and are in a specific burn-up state. In the existing method, the evaluation of the graphite content of a graphite element involves a systematic error. The new method enables this error to be utilised to distinguish between graphite elements and partly burnt-up fuel elements having the same graphite content, since the systematic error associated with the former is much greater than that associated with the latter.

Title: Distilling mash neutralisation - by injecting cold alkaline soln. into hot pressurised still
Inventor: HOLSTEIN ARNOLD
IPC: B01D3/00
Filed: 1976-06-16
Abstract: Mash, produced in distilleries, has a pH value of 4-5 and must be neutralised, i.e. brough to a pH of 7-8 before it can be discharged into the drainage system. This is achieved by introducing at the end of the distilling process into the pressurised hot still a charge of cold alkaline soln. which is matched in amt. and acidity to the mash and is allowed to act on it. This obviates the need for a special neutralisation plant which requires considerable capital investment and is not a paying proposition for smaller distilleries.
