IPC: B65G53/60
Filed: 1982-05-20
Abstract: 1. A method of filling silo vehicles with pyrogenically produced silicon dioxide with is fluidized in a storage container, characterised in that the fluidized pyrogenically produced silicon dioxide is charged to one or more positions of the silo vehicle container, by means of one or more pneumatic diaphragm pumps so that an excess pressure of up to 0.1 bar below the allowable maximum pressure limit of the silo vehicle container prevails therein during the filling process, and at the same time escapes through opened valves arranged on one or more dome-shaped covers and simultaneously through filter tubes which are arranged on the base of the silo vehicle container, and which are connected via a common collecting pipe to the external air, whilst the pyrogenically produced silicon dioxide is retained by filter cloths arranged in the dome-shaped covers.

Abstract: PCT No. PCT/EP85/00403 Sec. 371 Date Apr. 2, 1986 Sec. 102(e) Date Apr. 2, 1986 PCT Filed Aug. 7, 1985 PCT Pub. No. WO86/01144 PCT Pub. Date Feb. 27, 1986.The procedure to prevent the formation of condensation on tools that are heated in use and are cooled by a circulated coolant is particularly relevant to plastic moulding machines. To avoid the build-up of condensation from dampness on the cooled tools a dry air veil, as herein laid down, is produced by direct blowing-on of the tools, through which the cooling water temperature of the circulated coolant in the tools can be further reduced making shorter work cycles possible. By use of a special control equipment, the dew point on the tool surface is picked up which regulates the cooling water temperature accordingly.
