Patent EP-0293533-A2 (EP)
Inventor: FREDERIKSEN JEFFREY E
IPC: H03M7/30
Filed: 1987-10-22
Abstract: An audio signal is initially represented by a series of high-resolution pulse code modulated (PCM) data. A lower rate series of representative values are extracted from the initial series of PCM data. The PCM data are adjusted by offsetting in accordance with corresponding representative values and are then companded. The combination of the series of representative values and the companded PCM data provides a rate-compressed representation of the audio signal which is capable of being decoded after transmission or storage to reproduce the audio signal without substantial noise, distortion or loss of dynamic range. In one embodiment, the companding is performed by a floating-point conversion in which a common scale factor is determined for blocks of consecutive samples, a common offset is determined for each block by computing the arithmetic mean of the maximum and minimum PCM data values for the block and truncating the result, and the PCM data are adjusted by subtracting their corresponding common offsets. For encoding high-fidelity audio, preferably the audio signal is initially represented by a series of 16-bit PCM samples at a rate of at least 36 kilohertz, the block size is chosen to be 16 audio samples, and the encoded and   compressed data for each block includes a 160 bit frame consisting of an 8-bit block offset, a 3-bit block exponent, a 5-bit error correction code, and sixteen floating-point values each including eight data bits and one parity bit. This format permits 9 stereo audio channels and frame synchronization to be readily transmitted over a conventional video channel.

Abstract: The dry composition is of the type comprising at least two dry constituents and is intended to be diluted in a liquid, such as water, with a view to its application to a support in order to modify the surface thereof. It is characterised in that the first dry constituent 1 has an advantageously white uniform colour and the second, also dry, constituent 2 is formed from independent fibres of a colour different from that of the first constituent and of dimensions which are markedly smaller than those of the first constituent so as to be able to form a binder in which the first constituent 1 melts in order together to create a dry combination of granular appearance and substantially uniform colour resulting from the intimate dry combination of the colours of the two constituents 1 and 2. The second constituent is preferably formed from fibres 2 of approximately 1 millimetre in length, of the type commonly used for flock-coating articles. <IMAGE>

Abstract: The cutter (4) of the milling head has a guide part (20, 21) which engages into a guide (22, 23; 26, 27) extending in the adjusting direction of the cutter. The cutter (4) bears under spring force against a stop (32, 33) adjustable in the adjusting direction of the cutter and can be adjusted relative to a supporting part (7).For the adjustment of the cutter (4) the stop (32, 33) is adjusted in the adjusting direction of the cutter (4) which is thereby pushed after it under the spring force. The supporting part (7) itself is not adjusted. The readjustment of the cutter (4) is consequently simple and time-saving. <IMAGE>

Abstract: The semisynthetic preparation of human insulin and its derivatives from pig insulin or other insulin precursors of equivalent sequence entails use of the enzyme trypsin in immobilised form, and the trypsin can be reused several times after regeneration of activity. The activity of the carrier-bound trypsin must be at least 1500 U/g of dry carriers, the reaction being carried out in a medium composed of an aqueous buffer system and of an organic solvent mixture at pH 6.8 and 19 - 22 DEG C in the presence of Ca<2><+> ions. After the reaction is complete, the carrier-immobilised trypsin is removed by filtration, regenerated in aqueous acidic medium at pH </= 3 and can, after subsequent equilibration in the reaction medium, be reused. More than 50 reuses are possible depending on the medium.

Abstract: This invention relates to urethane linked hydroxy aromatic amines and to a process for producing such urethane linked hydroxy aromatic amines. The compositions are formed by initially reacting one equivalent aromatic diisocyanate with one equivalent of an alkylene polyol under conditions such that only one of the isocyanate groups reacts with one hydroxyl group of the polyol. Conditions are controlled such that only the urethane linked hydroxy aromatic isocyanate is formed. Then, the resulting urethane linked hydroxy aromatic isocyanate is hydrolyzed to form the amine.

Title: Method for producing voltage pulses
Inventor: POLLMEIER WERNER
IPC: H03K4/06
Filed: 1988-11-25
Abstract: The invention relates to a method for producing voltage pulses for controlling the switching operation in switched-mode power supplies. A voltage increase of a pulse generator is in each case initiated on reaching a first, lower threshold (A). The voltage increase is reset in the free-running mode when the voltage increase reaches a second (D) or a third (C) threshold, located between the first (A) and second (D) threshold. In the synchronisation mode, the pulse edges occurring in the synchronisation signal (Vsync) initiate the reset of the voltage increase. The advantages of the invention are that the switching current occurring as a result of the frequency difference during the transition from the free-running mode into the synchronisation mode are minimal and the generator operates reliably.

Abstract: A scroll type compressor includes a housing (10) having an inner chamber and fluid inlet and outlet ports connected to the inner chamber. A fixed scroll (13) is mounted within the housing and has a circular end plate (131) from which a first sprial element (132) extends. An orbiting scroll (14) is also mounted within the housing for orbital motion with respect to the fixed scroll, and includes a circular end plate (141) from which a second spiral element (142) extends. The fixed scroll and the orbiting scroll are maintained angularly and radially offset from each other so that the spiral elements interfit to form a plurality of line contacts between their spiral curved surfaces which seal-off and defined at least one pair of fluid pockets. The orbital movement of the orbiting scroll relative to the fixed scroll shifts the line contacts along the spiral curved surfaces of the spiral elements which changes the volume of the fluid pockets. The end plate (131) of the fixed scroll partitions the inner chamber of the housing into a suction chamber (18) and a discharge chamber (19). A sealing structure (30) is disposed between the inner peripheral wall (12) of the housing and the outer peripheral surface of the end plate of the fixed scroll. The sealing structure includes an annular cut-out portion formed in the outer peripheral of the end plate of the fixed scroll, an annular shoulder formed in the inner peripheral wall of the housing and an O-ring element disposed between the annular cut-out portion and the annular ridge.

Abstract: A modularly expandable digital single-stage ATM (Asynchronous Transfer Mode) switching network for high-speed packet-switched information transfer, comprising a preprocessing module (VVM), in which arrangement preprocessing is only carried out with respect to the matrix column but not with respect to the matrix output and the number of expansion inputs and the number of first outputs of the preprocessing module is 1/L, namely N, of that of the expansion module, this module containing a single FIFO store (SP) which can simultaneously enter 2N packets and simultaneously read out N packets and in which arrangement, to avoid so-called overtaking by packets, the order in time of packets in each case arriving on one of the N first-input lines of a preprocessing module (VVM) is replaced case by case by a spatial order on the N first-output lines of the preprocessing module (VVM). An overhead information filter (KF) only processes a part of the overhead information of the data packets for switching the packets to the relevant switching module column. In addition, a further preprocessing module (VVM) and a final processing module (EVM), which carries out final switching to the matrix output, are provided per matrix column, in which arrangement the first outputs of these preprocessing modules (VVM) are connected to the relevant inputs of the final processing modules (EVM). The final processing modules (EVM) do not have any expansion inputs or expansion outputs. The overhead information filter (KF) of the final processing module (EVM) processes a different part of the overhead information for the final switching to a matrix output.
