Patent DE-2741691-A1 (DE)
Title: Denture mounting in upper or lower jaw - using layer of wash-leather releasably secured to denture by self-adhesive base layer
Inventor: RIDINGER ALBERT
IPC: A61C13/07
Filed: 1977-09-16
Abstract: Full dentures are secured in the upper or lower jaw, without the use of adhesives or fixing powders, by means of a layer of absorbent leather (wash leather) which is bonded to the dentures by means of a base layer. The base layer has a self-adhesive side which is first pressed on to the dentures (and which also permits the layers to be removed and renewed.) A water-insoluble adhesive is then applied to the base layer and the absorbent layer is pressed on. The absorbent layer is cut to the appropriate size as necessary.

Title: Motor with gas-to-air heat exchanger - is built onto frame with radial gas outlet at non-drive end
Inventor: GARZMANN TRAUGOTT DIPL ING
IPC: H02K9/10
Filed: 1977-10-01

Title: Blending of liq. components in mixer - having vessel held between flat plates which can be adjusted for various vessel sizes
Inventor: KROEMMELBEIN KLAUS H DIPL KFM
IPC: B01F9/00
Filed: 1978-03-06
Abstract: Mixing of liquids takes place in a vessel mounted on a horizontal rotating axis and which is also rotated about its own axis. The unit is belt driven.

Title: Corrosion protection of coke oven extractor fan - by adding alkaline water to neutralise acidic gas droplets
Inventor: HOELTER HEINZ ING GRAD
IPC: C10B27/00
Filed: 1979-05-23
Abstract: Ventilators which extract the gases emitted during quenching or charging operations in coke over plant suffer rapid corrosion by droplets with an SO2 content. Rubber linings would be useless because hot gases may occasionally break out. It is suggested therefore to inject into the gas ahead of the demister, where it contains droplets at a rate of 2g/m3 with a pH-value of 6, a multiple amt. of alkaline fresh water with a pH-voltage of 8. The result is that the gas mixt. has an average pH-value of 7, i.e. it is neutral and causes no more corrosion to the ventilator.
