Patent DE-3941399-C1 (DE)
Title: Turbine outlet nozzle control - consists of slider moved by lever pivoted in casing
IPC: F02B37/22
Filed: 1989-12-15
Granted: 1991-01-03
Abstract: Control slide moves axially in the turbine housing to control the section of the outlet nozzle from one of two partitioned channels led through the housing. To control the sections of both channel (3, 4) nozzles (6, 7), the slide (9) should be arranged in the partition (2) between the channels and adjusted axially by an adjuster pref. designed as an externally operated rotary lever whose end fitted slide shoe reaches into the slide path. USE/ADVANTAGE - IC engines, turbochargers. Slide controls both channel sections to handle maximum exhaust flows, permitting channel shutoff to prevent flow transfer and thus ensure higher efficiency.

Title: Fault-tolerant digital computer circuit - has normal function blocks and redundant function blocks with switching control
IPC: H03K19/003
Filed: 1990-12-04
Granted: 1992-05-07
Abstract: The fault-tolerant digital device possesses a number of normal function blocks (B1...,C1...,..D5..) and also redundant function blocks which can be switched in by a control unit (S) instead of a faulty normal block when a fault has been detected in one of the normal blocks. The normal function blocks are combined into groups (B,C,D) of different blocks with similar basic functions and each group is provided with a superblock (BS,CS,DS) constructed so that it can perform the function of each of the normal blocks of a group, when it receives the input signals of the blocks of its group. The inputs of consecutive function blocks are connected with the outputs of the associated function blocks and in addition with the outputs of the superblocks assigned to the blocks and can be switched between them. USE/ADVANTAGE - The advantage is an improvement in flexibility. It is suitable for computer systems.
Patent DE-4102324-C1 (DE)
IPC: G10L19/00
Filed: 1991-01-26
Granted: 1992-06-17
Abstract: The transmission of digitised, block-coded audio signals makes use of scale factors formed in the block-coding of the digitised audio signals from the peak value of a sequence (block) of signal values and added to the scanned and possibly reduced signal values of the sequence concerned in quantified form. When the audio signals are coded, certain differences are formed by sign and amount from a number of k successive scale factors of a partial frequency band or a group of spectrum values of the audio signal divided into n partial bands or spectrum values (with n >/=  1). These (k-1)*n differences are arranged in value classes, each of which includes a number of one or several possible differences. To the sequence of (k-1)*n value classes is allocated -- separately for each of the n partial bands or spectrum value groups -- a transmission model of new scale factors consisting of control data and a sequence of new scale factors. The number of successive, different new scale factors within the sequence is thereby smaller than or equal to the number of successive, different scale factors of the partial band or spectrum value group of the audio signal under consideration. The control data identify the allocation of the new scale factors to one or more of the k blocks of the scanned and possibly reduced signal values of the relevant partial band or spectrum value group. When the audio signals are decoded, the appropriate new scale factors are allocated to the blocks of scanned and possibly reduced signal values using the control data. From the scanned and possibly reduced new scale factors, audio signals are again generated which correspond more or less to the original audio signals.
