Patent DE-3446145-A1 (DE)
Title: DC-discharge gas laser
Inventor: MANN OLAF
IPC: H01S3/097
Filed: 1984-12-18
Abstract: In the case of known gas lasers, a resistor and/or a remote cut-off tube are/is provided for compensation of the negative impedence of the gas-discharge path. This results in considerable power losses. In order to avoid these power losses, the invention proposes to provide an AC voltage source, having a high internal impedence, in the power supply section of the gas laser. The AC voltage source is connected - possibly via a transformer - upstream of a rectifier. A charging capacitor is connected to the output of the rectifier, in parallel with the gas-discharge path of the laser. The capacitance of the charging capacitor is so small that it can overcome the ripple on the output signal of the rectifier caused by the relatively high frequency of the AC voltage source, while being small enough reliably to prevent oscillation of the system. The AC voltage source preferably consists of a self-commutating chopper to which a series inductor is connected as a reactance.

Title: Windscreen for bicycle
Inventor: DIETZ BERNHARD
IPC: B62J17/04
Filed: 1985-01-23
Abstract: The windscreen for a bicycle, mainly for children being taken along on the child's seat at the front behind the handlebars, has the purpose of keeping the air flow away from the child. The essential concept is that, in contrast to the physically active cyclist, the motionless child needs special protection against the air flow. The technical solution is a transparent plastic plate which can be quickly and securely fastened on the bicycle in a three-point system using tubular clips and can easily be removed again. The position is in front of the handlebars so that the child being taken along on the child's seat has freedom to move and is protected.
Patent DE-3507095-A1 (DE)
Title: Control for a turbocharger with variable geometry
Inventor: HIRABAYASHI YUJI
IPC: F02B37/22
Filed: 1985-02-28
Abstract: A control for a turbocharger with variable geometry controls a cross-sectional surface of a restriction of a turbine, through which exhaust gas from an internal combustion engine is fed to the turbine. Control is effected on the basis of the rotational speed of the internal combustion engine and the amount of intake air fed to this. In addition, the control comprises a bypass device for bypassing the turbine in order to reduce the amount of exhaust gas fed to this by controlling the opening and closing of the bypass duct. This control is effected on the basis of the rotational speed of the internal combustion engine and the amount of intake air fed in. Both controls prevent a reduction of the amount of intake air fed in and improve the torque of the internal combustion engine in all operating ranges.

Patent DE-3533493-A1 (DE)
Title: Process for producing components from steel of high strength and at the same time high toughness, having these properties even after hot deformation
Inventor: MUELLER HANS DIPL ING
IPC: C21D9/00
Filed: 1985-09-19
Abstract: According to the invention, a bainite microstructure is obtained for steel-based components, which are subjected to hot deformation, by the addition of carbide-, nitride- and carbonitride-forming elements such as, for example, Nb to a steel having a carbon content of less than 0.3 per cent by weight; this microstructure is preserved even after hot deformation followed by controlled cooling. Alloy elements such as Mn, B and Mo assist the formation of bainite. A process of this type has the advantage that components such as, for example, lorry king pins, which are forged at temperatures of up to 1300 DEG C, no longer have to be re-hardened by a tempering stage after cooling, so that they still also have adequate toughness in addition to high strength.
Patent DE-3539057-A1 (DE)

Title: Method of selectively measuring the concentration of those gaseous and/or liquid substances in gases and/or liquids which absorb radiation ranging from IR to UV, and device for carrying out the method
Inventor: RINKE GUENTER DR
IPC: G01N21/31
Filed: 1986-10-04
Abstract: The invention relates to a method of selectively measuring the concentration of those gaseous and/or liquid substances in gases and/or liquids which absorb radiation ranging from IR to UV by means of the transmission procedure. The intensity, assigned to the substances li1...lin-1, of a beam periodically interrupted by means of filters Fi1...Fin-1 in test components Mi1...Min-1 is measured, each test component Mi being made up of a test signal and a dark signal. The object of the invention is to improve the process photometer of the type mentioned at the outset in such a way that a simultaneous measurement of the concentration of a plurality of substances is made possible. The object is achieved in that a value which is proportional to the measured value of the respective preceding test signal of the test component Mi-1 is subtracted from the measured value of the test signal of the test component Mi, and a value which is proportional to the measured value of the respective preceding test signal of the component Mi-1 is subtracted from the measured value of the dark signal of the measured component Mi, and in that the cross sensitivity which arises as a result of a spectral overlap of the absorption bands of the various gaseous or liquid components is compensated for analytically.

Patent DE-3720478-A1 (DE)
Title: Drying arrangement
Inventor: KORTMANN WERNER
IPC: F26B3/30
Filed: 1987-06-20
Abstract: The invention relates to a drying arrangement, in which a moist material web is guided along a number of radiant heaters arranged in a plane parallel to the material web in order to achieve at least a predrying. As the material web cannot be conveyed uniformly in the light of the handling stages existing before and after but undergoes occasional stops, the danger exists in the case of high-power radiant heaters of damaging the material by heat action as switching off the radiant heaters is not correspondingly inertia-free. The invention solves this problem by the radiant heaters being provided with pivotable reflectors which, by means of mechanical arrangements, can be pivoted out of an action position into a blocking position, in which latter they screen the material web from the radiation.
