Title: Gaseous additive for metal vapour laser - is used for reduction of density in metastable buffer gas or mixt.
Inventor: EICHLER HANS-JOACHIM PROF DR
IPC: H01S3/227
Filed: 1979-12-20
Abstract: The gaseous additive extends the emission period of a metal vapour laser, such as a copper ion laser in the ultra-violet spectral range, without exchanging or recycling of the buffer gas, e.g. neon. In addition the additive increases the emissive power and widens the emission spectrum. The additive increases the density of metastable atoms in the buffer gas, or its mixture. Pref. the ionising energy of the additive is lower than the energy of the buffer gas metastable atoms. In the above mentioned copper ion laser in the ultra-violet spectral range the additive forms a partial pressure of 0.01 to 5% of the neon pressure necessary for the laser operation. If the additive is used for a helium-selenium laser to widen the emission spectrum to wavelengths below 400 nm, the additive reduces the density of the metastable helium atoms.

Title: Antitheft system for motor vehicle - has alarm contacts bridged by fluid when vehicle is inclined (SE 23.2.81)
Inventor: KOLB HANS PROF DR
IPC: B60R25/10
Filed: 1980-05-06
Abstract: An anti-theft system for a motor vehicle comprises an electrically-powered alarm, a switching device (10) and an electric circuit (11) connecting the latter and the alarm. The switching device is attached to the motor vehicle, and is provided with electrical contacts (13,17) which automatically close the electric circuit (11) when the vehicle is in an inclined position. The housing (14) is suspended on gimbals so that, when the vehicle is parked, the axis is vertical, even if the vehicle is inclined in the longitudinal or transverse direction. The housing (14) is then secured with the primed alarm unit. This can be done with the aid of an electromagnet. The coil of the magnet is energised, when the alarm unit is switched on, so that the magnet holds a steel plate fixed to the exterior of the housing. If the orientation of the vehicle is then altered, the housing assumes an inclined orientation. Since the fluid level remains horizontal, it will touch the cover (19) at a predetermined inclination. Then the fluid (23) makes electrical contact between the cover (19) and the floor plate (17) so that the circuit between the wires (12,13) is closed, and the alarm is set off.
