Title: Output power attenuator for CB radio - uses quick-acting hot or cold conductors, e.g. light bulbs or limiter diodes, between transmitter output and antenna
IPC: H03H7/13
Filed: 1991-03-28
Abstract: With the spread of use of CB radios, it is often the case that there is only a distance of 30 metres between adjacent sets, and to obviate interference it is necessary to decrease output power. This is achieved by using attenuating components fitted with bright hot and cold conductors (light bulbs) or limiter diodes. This provides favourable attenuation during changeover between transmission and reception modes. ADVANTAGE - To suppress interference between adjacent CB radios.

Patent DE-4122484-A1 (DE)
Inventor: FENNEL HELMUT
IPC: B60T8/88
Filed: 1991-07-06
Abstract: A circuit for detecting defects in wheel sensors contains circuits which process and evaluate the sensor signals (s1-s4), determine the speed (vRmax, vRmin), deceleration and acceleration (aR) of the individual wheels, and compare these values with each other and with predetermined threshold values (a0, v0, v1, -a1). When signals or signal combinations typical of a sensor defect are found, the control is deactivated after a predetermined interval (T, T1+T2). If the measured acceleration values (aR) are below an overspeed threshold (a0) and the speed of one of the other wheels is below a lower speed threshold (v0), the control is deactivated once the speed of a wheel (vRmax) passes an upper speed threshold (v1). Should the measured acceleration (aR) lie above the overspeed threshold (a0), and the measured speed (vRmin) lie below the lower speed threshold (v0), a timing is activated as soon as the measured speed (vRmax) exceeds the upper speed threshold (v1). The control is deactivated after a predetermined interval has elapsed.

Patent DE-4125801-A1 (DE)
Title: Increased absorption of carbon-di:oxide laser radiation by workpiece - involves using nitrogen@ gas blanket and focussed pulsed laser simultaneously with the continuous high power laser
Inventor: BERGMANN HANS WILHELM PROF DR
IPC: B23K26/12
Filed: 1991-08-03
Abstract: The absorption of a cw-CO2-laser in the material of a work object is increased by focusing simultaneously the radiation of a pulsed laser on the work piece while maintaining a gas blanket of N2 or a N2 contg. gas. The CO2-laser pref. has a wavelength of 10.6 micron and the pulsed laser has a wavelength 9.1-11.1 micron. The laser pulses pref. have a duration of from 10 nano-secs. to 100 micro-secs. and a frequency of 10 Hz to 1 KHz. USE/ADVANTAGE - The use of a N2-blanket reduces the reflection of laser energy together with the use of the pulsed laser which generates a plasma in the gas. As a result the absorption of laser power by the workpiece increases giving faster heating and less danger to the operators. The pulsed laser can be focused through the same lens as the cw-CO2 laser, or through a separate lens. The energy of the pulsed laser does not have to be very high, e.g. 100 mJ which can give up to 10 power 8 watt/cm2 peak energy, since the pulse duration is short. Fig.1 shows the effect of a N2 blanket with and without the pulsed laser in terms of energy reflected from the work surface. The method is used for welding.
