Title: Basic industrial wastes neutralization - by controlling carbon dioxide admixture before static mixer by basicity meter in mixer outflow (NL071276)
Inventor: VERDER ANDREAS FRANCISCUS
IPC: C02F3/12
Filed: 1975-06-05
Abstract: Industrial wastes with a high basicity are neutralised before they are discharged into the drainage system. The basic liquid is heated and carbon dioxide is added to it. The mixt. is then passed immediately through a static mixer; the pH value at the outlet of the latter is measured and the rate of CO2 addn. is controlled accordingly. This eliminates the possible prodn. of sulphates or chlorides which occurs when acids are added for neutralisation. The process is less expensive than when air is percolated through the effluents.

Title: Long acting fertilizer prodn. from acidic tars or resins - by neutralising with alkaline substances having fertilizer activity
Inventor: PETZNY WILFRIED DIPL ING DR IN
IPC: C05C3/00
Filed: 1975-08-13
Abstract: Long-acting fertilizers are produced from acidic tars and acidic resins obtd. in the refining of lubricant oils and in the regeneration of used oils by treatment with conc. sulphuric acid. The acidic tars or resins are neutralized by stirring into aq. solns. of alkaline substances having cations with fertilizer activity. The resulting mass is filtered off and compressed into suitable shapes. The surface of the moulds is pref. previously dusted with chalk flour to prevent sticking. Process utilises starting materials the disposal of which would otherwise lead to pollution problems. The sulphur content of the tars and resins has a useful fertiliser effect. Weathering of the product leads to slow release of the fertiliser components and the carrier itself gradually breaks down to a dark crumbly material which has a favourable loosening effect on the upper layers of the soil and favourably influences soil mechanics. In an example, acid tar was added portionwise to a stirred suspension of CaCO3 in water, then further CaCO3 was added, the mixt. was stirred, and further CaCO3 was added to improved agglomeration. The product was a crumbly material.

Title: Factory drying space for cigarette filter tips - using sensor controlled stores over tip making and using machines connected by pneumatic conveyor
Inventor: WAHLE GUENTER
IPC: A24C5/35
Filed: 1975-09-10
Abstract: Certain types of cigarette filter tips require time to dry before they pass on to the next process. The present drying method requires no floor space. The required storage is created partly over the machine that makes the tips and partly over the machines that will use them. The tips, arriving singly, are first stacked by sensor control, several deep and then pass to the main store, where they are dried enough to be handled by the pneumatic conveyor that distributes them to several machines. A buffer store at the entry to the main store caters for variations in supply to, and demand on, that store. The pneumatic distribution channels lead to stores of precisely similar type, placed over the machines that will use the tips. Here the tips complete their drying.
