Title: Silicon semiconductor sepn. from reacting gases - watched using inspection tube with window protruding into reaction chamber with electrodes which avoids opacity developing on window surface
Inventor: RUCHA ULRICH
IPC: H01L21/205
Filed: 1977-09-29
Abstract: Semiconductor material esp. Si is deposited on a heated carrier from a reaction gas contg. a halogen cpd. and H2. The device consists of a base plate with a dome made from quartz, glass, "rotosil" or steel over it. The plate has openings for the reaction gas to enter and leavy by and a mounting for the support plate electrode. There is also a tube protruding into the reaction space which has an observation window. The window is located at a distance from the end of the tube such that condensation onto its is virtually eliminated. The tube is made of the same material as the base plate and the window is of quartz. Used for mfg. si semiconductors. Avoids the problems with previous windows which become obscured due to material condensing out on them and preventing viewing.

Title: Radioactive sewage delay-tank system for activity control - esp. for use with water-conserving toilets in nuclear therapy wards
Inventor: SKLORZ WILHELM
IPC: G21F9/22
Filed: 1978-11-30
Abstract: To store radio-active toilet sewage during activity decay to permitted discharge levels, >=2 similar tanks are controlled to act alternately as collecting and decay tanks such that the collector tank filling-time and the required decay time are of similar magnitude. An air-jet is supplied to each tank or alternatively a stirring means supplemented by alkali and oxygen dosing equipment is fitted. A pump circulates the upper stratum of the decaying batch through an external homogeniser and back into the tank through a distribution header housed inside. Tank activity measurement may be arranged to occur automatically on completion of filling, the required decay time for the batch being then calculated by a programme controller which operates the collecting and decay tank valves. The arrangement minimises the vol. of tank storage required for water-conserving toilets discharging radioactive sewage, (e.g. from nuclear therapy hospital departments). The water conservation (e.g. 1 litre per toilet) leads to high-density discharge requiring the special storage and transporting measures described here. The degree of automation of the arrangement can be reduced without breaching the invention.
