Patent DE-2636874-A1 (DE)
Title: Increasing wettability of surface coated with low surface tension liq - by applying powder layer adhering on one side
Inventor: NOETHE BJOERN DIPL CHEM
IPC: C03C25/106
Filed: 1976-08-17
Abstract: Wettability is improved by coating one surface with a thin layer of a powdery material. On one side, powdery material is wetted so well by the liquid that powder adheres to liquid. On the other side, powder exterior remains free from liquid for the time required for a specific process. Process can be used for coating light-wave conductor fibres or tow, e.g. with silicone oil, followed by a hardening resin. On wetting silicone oil with powder layer, powder layer can be covered with a resin soln. which is left to harden. Process can be used for sheathing optical glass fibres.

Title: Automatic infrared radiation flame monitor - converts photoresistor voltage to operate switching transistor with two stable states
Inventor: LAHME GEB ZEHMISCH BAERBEL
IPC: F23N5/08
Filed: 1976-09-29
Abstract: The infrared radiation flame monitor utilises the intensity fluctuations in the infrared radiation as flame combustion characteristics. The arrangement operates automatically and reliably due to the use of semiconductors for amplification and signal processing. The radiation received by the lead sulphide photoelectric resistors is converted into square wave signals after amplification of the voltage of these resistors. The input signal is fed, after processing, by an impedance converter to a charging capacitor with voltage and time determining circuits. The output voltage is used for a switching transistor so that this transistor is operated only in two stable states.

Title: Release agents for polyurethane moulding materials - consisting of methyl siloxanes reacted with aluminium alkoxides
Inventor: KOERNER GOETZ DR
IPC: B29C33/64
Filed: 1977-04-29
Abstract: Release agents are prepd. by reaction of methyl siloxane oil of formula HO- Si(CH3)2-O- nH (I) (in which n is 5-20) with Al alkoxide of formula (RO)3 Al (II) (in which R is 2-4 C alkyl), in proportions such that the molar ratio OH/OR is 0.8-1.2 (pref. 1.0 approx.).

Title: Car door lock with microswitch status detector - uses indicator circuit closed when door is fully closed
Inventor: RAFFELSIEFER KURT
IPC: E05B85/26
Filed: 1977-06-22
Abstract: The car door lock incorporates a forked rotating latch acting with a fixed pin, and is locked by a hooked lever which engages with a projection on the latch when the door is fully closed. A micro-switch closes an indicator circuit when the deflection of the hooked locking lever is of the magnitude occuring only when the door is fully closed.
