Title: Aquaplaning or wheel spin warning system for vehicles - uses individual wheel sensors providing signals proportional to speed, reference unit and comparators
Inventor: LORECK HEINZ
IPC: B60R16/02
Filed: 1977-12-05
Abstract: The warning system consists of sensors associated with each wheel of the vehicle which are connected to transducers.

Title: Flame monitor with on=off switch - generates pulses from flame current for fuel valve actuating solenoid
Inventor: OCHS WALTER
IPC: F23N5/12
Filed: 1978-03-08
Abstract: The flame monitor for a burner flame generates direct current when burner flame exists. The output of the flame detector circuit is connected to a switching system which keeps fuel supply open in presence of flame. The monitor is inherently reliable and safe. A switch is switched periodically off and on. In on state it short circuits the input of the flame detector circuit. This ensures that the control input of the switching system consisting of relay is powered with periodic pulses into the flame effect. The control system current circuit of the switching system relay has a second switch which switches the pulses periodically on and allows passage of the current which switches the switching system on.

Title: Telescopic radio aerial for motor vehicles - has variable tuning signal generator coupled to setting device adjusting aerial length according to signal magnitude
Inventor: BARSKE HEIKO DR
IPC: H01Q1/10
Filed: 1978-09-16
Abstract: The longitudinal adjustment of a radio telescopic aerial is carried out by a device containing a signal generator responsive to the tuning frequency. It is connected to an adjuster for the telescopic aerial length in dependence on the signal strength. Preferably a variable resistor is used as the signal generator, which is mechanically connected to the radio receiver tuner. Alternately a capacitor connected in the same manner may be used for this purpose. In this way the increase of signal noise, inherent in the radio receiver amplification of low voltage aerial signals, can be avoided, particularly in the ultra-short wave band.
Patent DE-2841247-A1 (DE)
IPC: C09D161/00
Filed: 1978-09-22
Abstract: One component of this two-component paint is a phenolic, amino, alkyd or acrylic resin precondensate or a mixture of such precondensates, and the second component is a hardener consisting at least in part of hydrofluoric acid. The components can have identical or different solvents and/or solvent mixtures. A mixture of the two components, of which at least one is dissolved in a solvent, is applied to a glass or quartz substrate in the form of a film and the coating is allowed to harden at a temperature of up to 100 DEG C. Before application the mixture can have added to it additives, such as pigments, dyes, lubricants, wetting agents, suspending agents, fillers and/or delustrants. The mixture can be applied with rolls, by spraying, brushing, rolling or dipping in layers of up to 50  mu m. The ready-mixed two-component paint has a pot life of more than 24 hours and forms a strong and durable paint film with excellent adhesion to glass and quartz, in particular the low curing temperature being advantageous.
