Title: Soil-improving compositions - contg. finely ground clay materials aggregated with organic substances
Inventor: SEIFERT ERNST
IPC: C05G3/80
Filed: 1974-10-12
Abstract: In a process for the production of extendable colloidal aggregates for soil-improving agents from finely ground clay materials (e.g. bentonite) by incorporating known org. additives which seve directly to promote aggregation (e.g. urea of methylcellulose), there are also added organic cpds. having an effect on the water-stability of the aggregates. One group of pref. water-stabilising additives is hydrocarbon cpds. with free charges or functional groups such as e.g. unsaturated alcohols or monocarboxylic acids, these cpds. being used in an amount of ca 2-5%. Another pref. group of water-stabilising additives is saccharides (e.g. sucrose), these being used in an amount of ca 5-15%. The additives impart lasting hydrophilisation to the colloidal aggregates, so that soil treated with teh new soil improving agens have long-lasting water-retaining properties. It is advantageous to use relatively high concentrations of saccharides because these undergo rapid microbial reaction to form new waterstable, hydrophilic structures.

Title: Fluorescent screens for colour picture cathode ray tubes - having intermediate layer between illuminant strips and aluminium foil backing
Inventor: MALIK ASHIQ ALI
IPC: H01J29/28
Filed: 1975-10-11
Abstract: The screen has a large number of adjacent illuminant strips. After application of these strips, the cathode side of the screen surface is coated with a thin Al foil. After application the illuminant strip and before application of Al foil, a 1-20 mu coating is applied. The coating has a basic colour which deviates from that of the illuminant strips as little as possible. The coating is not transparent, but as translucent as possible. The coating can withstand temps. of 380 degrees - 450 degrees C. Fluorescent screens having the illuminant coating applied in stripe form frequently show the Al backing foil between the strips if these are not close enough together, even when the tube is not operating. This defect is avoided by introduction of an intermediate coating as in the invention. In an example, a glass surface for a cathode ray tube was coated in parallel adjacent strips with 3 illuminants in succession and then sprayed with K silicate to leave a silicic acid layer before final application of Al foil. The treatment effectively filled any space between strips which might otherwise allow the Al foil to be visible to the viewer.

Title: Screwed joint tightening process - uses axial blows before final tightening operation to induce artificial settling
Inventor: HAAS NORBERT
IPC: B25B21/02
Filed: 1975-11-26
Abstract: The process is for tightening up a screwed joint, this being first pulled up to the rated torque and then tightened up again after settling. The settling of the join is artificially induced by a number of blows onto the screw or bolt and in a direction coaxial with it. This can be done before final tightening, or the joint can be pulled up beyond the rated torque and then artificial settling carried out. Alternatively artificial settling and final tightening can take place at the same time. A spanner can be used in which axial blows are applied automatically when the set torque is reached.
