Title: Solderable metallisation - of semiconductors and insulators, with high electrical transverse conductivity
Inventor: FLOHRS PETER DIPL PHYS
IPC: H01L21/00
Filed: 1971-09-02
Abstract: Solderable metallisation with high electrical transverse conductivity is produced on a substrate by applying first an Al layer is not 3 mu m thick and then a comparably thin Ni layer, tempering in a non-oxidising atmos. below the temp. at which a liquid phase forms at the interface between the substrate and the Al and then applying a second Ni layer which likewise is thin in comparison to the Al layer. The technique is useful for metallising Si semiconductor output elements and insulators, esp. of SiO2. It eliminates the usual disadvantages associated with difficulty of soldering small metallised areas and high specific electrical resistance. Tempering is carried out at 450-550 degrees C. Typical thicknesses are 10 mu for the Al and 0.2 mu for the Ni coating.

Patent DE-2331789-A1 (DE)
Title: Car lamps circuit function monitor - uses magnet with lamp and auxiliary conductors which control operation
Inventor: PANTENBURG AXEL
IPC: B60Q11/00
Filed: 1973-06-22
Abstract: The ring magnet is threaded by a conductor which carries the lamp current. It is also threaded by an auxiliary conductor, and there is a key controlling the supply from the battery. The currents of the two conductors produce opposing magnetization effects, the momentary switching of the test key producing a remanent polarization of the magnet which is driven into saturation. When a lamp is turned on this ensures demagnetization, and this causes an induction wave in the auxiliary conductor traversed by a current fed to an amplifier. The latter is connected to display unit and the presence or absence of a signal during lamp switching will indicate whether the latter functions.

Title: Surge voltage generator with capacitors charged via resistors - using transformer coupled to spark gap cascade and with selectable output tappings
Inventor: HENNEBERG HANS
IPC: H03K3/537
Filed: 1973-12-17
Abstract: The surge voltage generator produces voltage pulses whose amplitudes can be altered to suit different applications but whose pulse energy remains constant despite the changes in amplitude. A transformer has its primary tappings coupled to a bank of capacitors, forming a series cascade with spark gaps and charged from a high voltage source, e.g. 8 kV, overcharging resistors. The transformer secondary winding has several output tappings. The selectively tapped transformer enables a large range of pulse amplitudes with constant energy to be selected. The energy can be altered by altering the widths of the spark gaps. This arrangement permits wide division of the tapped surge voltages.

Title: Oil level indicator for IC engine - has electric contacts closed by membrane displaced by oil pressure
Inventor: GRUPP EBERHARD
IPC: G01F23/18
Filed: 1974-12-07
Abstract: The indicator consists of a tube (1) made of plastic material dipping into the oil sump. Its lower end is closed by an elastic sleeve (2) the base of which is formed by a membrane (3). Electric leads (6) run down the inside of the tube (1) and terminate in two contacts within the elastic sleeve. The base membrane (3) carries a conducting plate (5). As the oil level rises the static pressure raises the base membrane, deforming the sides of the elastic sleeve in doing so, until at a sufficient level the conducting plate on the base membrane touches the terminal contacts and completes the electric circuit between them. This enables the circuit to be used to illuminate an oil level warning light.
