Title: Non-drip stopper for honey dispenser - has cutting edge round bottom of shaped stopper preventing excessive build=up
IPC: A47G19/18
Filed: 1977-09-21
Abstract: So that when required the flow of honey ceases immediately through the outlet opening at the bottom of a container the stopper (2) located inside the container extends in the closing direction where it has at its lower end a peripheral cutting edge (19). The outer surface (23) of the downwardly extending part of the stopper (2) corresponds at its lower end (16) to the side of the opening whilst at it its upper end it exceeds the size. The desired amount of honey can thus be measured whilst a sudden surge is prevented. If the base face (22) of the stopper (2) is raised up inside the peripheral cutting edge (19) honey is prevented from collecting on the underneath of the stopper and then dripping.

Title: Swimming pool water treatment - controls halogen and ozone addition by redox potential measurement
Inventor: BACHHOFER BRUNO
IPC: C02F1/76
Filed: 1978-03-23
Abstract: In a water treatment system for swimming pools the water in circulation receives an admixture of a halogen and is exposed to the action of ozone. During operation, the redox potential of the pool water is measured and the treatment plant is put into circuit automatically at certain intervals. When the redox potential rises to preset value, it is cut out again. This guarantees that the water is free from germs but that the treatment plant operates for a minimum of time. The operating costs are thus reduced. The amount of substances with an oxidation capacity is kept low enough not to molest the users of the pool.
