摘要： Dichloropinacolone is produced by introducing into pinacolone twice the molar amount of chlorine, the exothermic reaction mass being cooled initially to maintain the temperature below about 50.degree. C. until about 60 to 80% of the chlorine has been introduced, and then heating the reaction mass to a temperature above 50.degree. C. during introducing of the remainder of the chlorine, thereby to produce dichloropinacolone, and terminating chlorine introduction when the dichloropinacolone content of the reaction mass is at least about 97%. The molten product is added to an aqueous solution of an alkali maintained at a temperature of at least about 50.degree. C., the alkali being present in more than three times the molar amount of the dichloropinacolone. To the resulting solution of a salt of 3,3-dimethyl-2-hydroxy-butyric acid, brought to a pH of about 9 to 12, there is added approximately the stoichiometric amount of potassium permanganate. Solid MnO.sub.2 precipitates out and is separated from the substantially pure dissolved salt of 3,3-dimethyl-2-oxo-butyric acid. The produce is a known compound suited for further syntheses.

摘要： A device for the transportation of flowable material in pulverulent, granular, lump, granulated or pasty form in a feed pipe comprises a coaxial endless feeder screw which is rotatable in the forward or reverse direction and a drive mechanism for driving said screw. The drive mechanism enables one to obtain a feed motion without rotation and a rearward motion with a forced, regular rotation of the endless screw so that the material to be transported remains axially stationary during the rearward motion. Owing to the dense column of material to be transported the bearings may be suppressed; if they are provided, they will have to be arranged outside the conveying stock. The endless screw is designed as a single piece screw and the distance between the screw and the feed pipe is slightly bigger than the average size of the grains or lumps of material to be conveyed. The device is preferably used for the supply of pneumatic or hydraulic conveyors.

摘要： A device for loading containers that are open or can be vented, containers for fine particulate materials, said device being part of a pneumatic conveyance system, in particular such a system using dense layer transportation, where the said device comprises essentially a tube-shaped casing, a lifting element, a closing element and a lifting rod which connects the lifting and closing elements and enables the distance between these elements to be varied. The combined weight of the part of the lifting element, that can be moved in the axial direction (A), the closing element and the lifting rod is greater than the elastic force of the lifting element but is smaller than the product of the difference between areas (F.sub.H) and (F.sub.M) and the positive pressure in the supply line acting on the lifting element. The distance (h) of the closing element from the lower edge of the casing is smaller than the stroke of the lifting element. The device can be employed on an alumina silo for charging fused salt electrolytic cells used in the production of aluminum, on a plastic powder silo, a cement silo or a quartz silo for foundries.
