Title: Electric guitar amplifier producing high gain and crunch blues sounds without extra valve stages - includes non-amplifying upper tone generating selectively connectable distortion stage
Inventor: STAMER HANS
IPC: G10H3/18
Filed: 1992-10-29
Abstract: The amplifier has an amplifying input (1) and an output (2) with several amplification stages (7, 8, 9, 26). At least part of the amplifier is over modulated by an input signal level exceeding a given value. At least one stage comprises an amplifier tube (8, 9). Selectively variable upper tone spectra provide different sound characteristics, namely a High-Grain Sound with dynamic, intensive upper tone spectra, influenced by the method of playing, and at least one further sound with a less intensive spectrum, e.g. clean sound or crunch-blues-sound. To reduce the number of amplifier tubes necessary and to simplify the conversion between the different types of sound, a non-amplifying upper tone generating, selectively connectable distortion stage (10, 11) is provided. ADVANTAGE - Can switch between different types of sounds without additional circuitry.

IPC: B24B49/02
Filed: 1993-01-29
Abstract: The measured value is compared with a value interval, and the feed pressure is adjusted such that it is increased on non-reaching the interval, and reduced on its excess. If the measured value lies within the interval, the feed pressure is maintained unchanged. The feed pressure is changed in stages.

Title: Process for producing a tubular lining hose
Inventor: BRANDENBURGER JOACHIM
IPC: F16L55/165
Filed: 1993-08-06
Abstract: The invention relates to a process for producing a tubular lining hose for use in sewer repair work and to an apparatus for carrying out the process and also to the lining hose itself. In the process, a resin-impregnated fibre band (sliver) is helically wound into the form of the hose, the mutually facing side edges of the fibre band overlapping. Furthermore, the inner side of the lining hose thus produced is provided with a protective film. This technique has the advantage that lining hoses for various sewer sizes can be produced labour-unintensively. According to the invention, first of all a film hose, forming the protective film, is produced by helically winding a film band onto a mandrel and then the resin-impregnated fibre band is wound onto it. The production operation for the lining hose is thereby further simplified.

Title: Component material fluctuation determn. and time point detection method
Inventor: METZNER KLAUS DR
IPC: G01N33/44
Filed: 1994-03-11
Abstract: The method involves using a column filled with absorbent which is distributed in several equal successive sections. The gas flow continuously passes the sequence of these sections. The sections of the column are separated from each other after the blocking of the gas flow. The components held back in the respective sections during the duration of the gas flow through the column are analysed in the known manner independently from each other. The time point of the fluctuation of the components is determined reactively from the partial alteration of the components in relation to the sequence of the n sections of the column.

Patent DE-4431446-A1 (DE)
Title: Generator of local interrogation fields for transponder
Inventor: KOSTER NORBERT H L DR ING
IPC: H01Q1/22
Filed: 1994-09-03
Abstract: The transponders derive their operational energy from the interrogation field and simultaneously generate useful signals. These are two identical, magnetically closely coupled coils (L1,2) which divide feed signals (55) from the transmitter on a feed line (K1) into two signal paths (SA1,2) such that the original total power is halved. Thus the common magnetic flux through the two coils disappears. Two, only slightly, or not at all, coupled frame aerials (R1,2) are each excited by the half-feed signal power and generate a local inter-rogation field. The transponder generates useful signal from the receiver reception signal, due to a suitable capacitive (CES1,2) on magnetic coupling to the coil arrangement.
