Title: Chlorine dioxide production from sodium chlorite and acid - with safety device preventing mixing if pump fails
Inventor: MILANATO FRANCO
IPC: C01B11/02
Filed: 1973-08-27
Abstract: An appts. for producing chlorine dioxide by reacting an acid and an aq. soln. of sodium chlorite comprises a reaction vessel supplied from two containers with the reaction components; each component feed line contains a metering valve; a water injection pump creates suction so that the components flow into the reaction vessel. In the feed line from each component storage container there is a vacuum breaking valve which permits air to enter the feed line as soon as the water supply to the water-jet pump is interrupted. The possibility of the two components becoming mixed if the water-jet pump stops is prevented. This occurrence could possibly lead to an explosion.

Title: Drinking beaker ready filled with flavour extract - has false bottom containing measured quantity of extract covered by detachable membrane
Inventor: FAHLBUSCH RAIMUND
IPC: B65D81/00
Filed: 1973-09-12
Abstract: The drinking beaker which may be of the usual conical stacking type has a false bottom containing the correct amount of a flavour extract, such as coffee, lemonade or the like, so that to prepare the drink it is only necessary to add the hot or cold liquid. The flavour extract is covered by an intermediate base, which comprises a ring and a membrane and the membrane is of the same material as the beaker and has a larger diameter than the inner diameter of the ring. The membrane may be stuck to the ring by an 'adhesive' such as honey which dissolves as soon as the liquid is poured in, and if the membrane is mounted beneath the ring it cannot interfere with drinking, since it is held back by the ring.

Title: Cracked hydrocarbon gas cooling - by heat exchange with molten lead circulating by compressed nitrogen
Inventor: SHIRAIWA MASATOYO
IPC: F28D15/00
Filed: 1973-11-05
Abstract: High-temperature reaction gases, produced by thermal cracking of a hydrocarbon, are cooled rapidly by indirect heat exchange between them and a molten metal (lead) held at a prescribed temperature (inlet 380-400 degrees C., outlet 480 degrees C.). The molten metal is circulated by a pressurised inert gas (nitrogen) and the condensation of the heavy components contained in the gases is prevented. This eliminates the formation of coke inside the heat exchanger and ensures an even function over long periods. The cooling temperature can easily adjusted and controlled for a certain hydrocarbon.
