Title: Variable speed reproduction of audio signal without spectral change - dividing digitised audio signal into blocks, performing transformation, and adding or omitting blocks before reverse transformation
Inventor: GOERING HANS-GUENTER DIPL ING
IPC: G10L21/04
Filed: 1991-01-16
Abstract: After digitising an analogue audio signal, consecutive samples of the timing signal are divided into a series of blocks, each block containing an equal number of samples. A transformation is performed on each block, and owing to doubling or omission of blocks, the original number of blocks is changed. The modified series of blocks is converted back into a series of sample blocks by reverse transformation, and this series of blocks forms the consecutive samples of the timing signal having a different reproduction speed. The omission of blocks raises the reproduction speed, the addition of blocks reduces the speed. USE - For dubbing of synchronised audio track in film or video, for synchronising audio signals in sound studio, or for use in audio typing systems, etc..

Patent DE-4134492-A1 (DE)
Inventor: FRIESINGER GUENTER
IPC: H01R4/68
Filed: 1991-10-18
Abstract: Bores at the cold end of a coolable high current junction piece project into the heat exchange zone. An insert fitted with a superconductive wire is inserted into each bore and conductively connected with the wall of the bore by further steps, so that it conducts well current and heat. During operation, this design decouples heat generation (no I<2>R) in the area of the bores. Heat generation is limited to the clamping area between the superconductive component and the cold end of the current supply on the one hand and the normal conductive heat exchange area and hot end on the other hand. By adapting the flow of coolant to the working current, a purely monotonous ascending temperature curve can be maintained along the current supply for all currents.
