Title: AF amplifier with response control - has signal from amplifier controlling relative gain over frequency ranges
Inventor: DODSON III GEORGE B
IPC: H03G5/16
Filed: 1979-06-08
Abstract: The audio frequency power amplifier includes a variable gain circuit responding to a reaction signal arising from the power amplifier so as to modify the gain of the system in one range of frequency w.r.t. that in another. This reaction signal from the power amplifier is coupled to the gain control circuit so as to modify the relative gain. This prevents an audible difference in the amplifier response to different spectral components in the range of controlled frequencies. The coupling may be an active equalisation circuit, or may comprise a variable resistor or light source illuminating a photosensitive resistor.

Title: Injection of carbonaceous fuel or oxygen into molten iron - using spring loaded valve; esp. for steel-making converters
Inventor: BROTZMANN KARL
IPC: C21C5/48
Filed: 1979-08-24
Abstract: Below the surface of molten iron in a vessel, e.g. a converter, are tuyeres embedded in the refractory brickwork in the vessel. Either fuel suspended in a carrier gas, or oxygen, is fed to the same inlet channel leading to the tuyere, and esp. into an inner tuyere tube, which is concentrically surrounded by an outer tube fed with gas- or liq- hydrocarbons. The alternate feeding of the fuel in its carrier gas, or oxygen, is achieved using a valve with two seats. In one position of the valve, only oxygen flows to the tuyere inlet pipe; in the other position of the valve only the fuel in its carrier gas flows into the tuyere inlet pipe.. The method is esp. suited to the converter steel making described in DE 2838983, where coal or coke can be blown into the converter. Tuyere blockage by the solid fuel is avoided.

Title: Sail-board mast foot coupling holding arrangement - is spring clip engaging mast pin peripheral groove to depth variable by moving clip
Inventor: TULL GOTTFRIED
IPC: B63B35/79
Filed: 1980-01-15

Title: Automatic calibration of opto-electronic classification arrangement - using stored calibration intensities converted into correction factors for automatic adjustment
Inventor: HEINHAUS MATTHIAS ING GRAD
IPC: B07C5/342
Filed: 1980-10-23
Abstract: An arrangement for optoelectronic classification of solid bodies in terms of colour and/or structural properties contains a group of photosemiconductor elements with at least one associated light source. A discriminator operates a control element according to the value of a summed signal compared to a threshold value. The arrangement enables automatic calibration and adjustment either each time it is switched on or at shorter time invervals. A computer forms a number of calibration factors corresp. to the number of photosemiconductor elements from calibration illumination intensities stored in a digital memory. The digitised outputs of the photosemiconductor elements are multiplied by the calibration correction values whilst the elements are illuminated by the illumination intensity to be measured and the discriminator looks for max. differences of corrected values.
