Title: Ejector coupling in die, casting machine - has adjustable cylinder to cause snap-fitting ball joint to lock to compensate for axially non-alignment between mandrel and main ejector body during initial stages of operation
Inventor: PIJPERS TEUNIS
IPC: B29C45/17
Filed: 1991-02-25
Abstract: Ejector coupling for the releasable connection between an injection die casting machine and its work tool in which an adjustable cylinder (12) inside the main body (7) can be moved to cause the snap fitting ball joint (9) to lock into a mandrel moving into the conical guide (11) or to release the mandrel by taking up the ball (9) inside grooves in its own surface. The connection piece (18) is connected to the receiver socket (3) via the axial force of the mandrel with radial play between the piece (18) and adapter plate (2). ADVANTAGE - Faulty alignment between the mandrel and main body can be compensated for by the radial play between piece (18) and main body without harming the reliability of the connection joint.

Title: Determining beat frequency of modulated pulsed signals - esp. from laser doppler anemometer used for fluid velocity measurement
Inventor: SCHROFF GERHART
IPC: G01R23/14
Filed: 1991-06-07
Abstract: Determination of the beat frequency of amplitude- or intensity-modulated pulsed signals, esp. scattered light signals emitted by moving particles and modulated by spatially alternating light/dark effects, is carried out by (a) initiating at the beginning of the signal, a scanning  operation which is interrupted at the signal end; (b) measuring, during the scanning operation, the time-dependent signal intensity in a time sweep adapted to the beat frequency and (c) evaluating the resulting measurement sequence to determine the beat frequency. A system for carrying out the determination is also obtained. USE/ADVANTAGE - The process is esp. useful for signal processing in optical velocimeters and esp. laser Doppler anemometers for non-contact local measurement of fluid velocites. It allows determination of the beat frequency of modulated pulsed signals in a wide frequency range and with high measurement rates.
Patent DE-4121478-A1 (DE)
Inventor: ARWEILER HANS WERNER DIPL ING
IPC: H04L1/24
Filed: 1991-06-26
Abstract: A flow of data (DS) from a data source (1) passes to a data receiver (9) via an intermediate path (5) and a transmission path (7). Before entering the transmission path (7) the flow of data (DS) is scrambled in a predetermined manner and unscrambled in the same manner on leaving the transmission path (7). A bit error function e(n) is obtained from test data (TZ) inserted into the flow of data (DS) at the data source and evaluated according to its period length (N). A bit error (BF) occurring before scrambling goes unmultiplied to the data receiver after unscrambling, whereas a bit error (BF) occurring on the transmission path (7) is multiplied by a period length (Nv) specific to the descrambling. A comparison of this period length (Nv) with the period length (N) of the bit error function (e(n)) makes it possible to locate the origin.
Patent DE-4122530-A1 (DE)
Inventor: DEMMERING GUENTHER DR
IPC: B01J31/04
Filed: 1991-07-08
Abstract: The invention concerns the transesterification of fatty-acid glycerides with lower aliphatic alcohols, the reaction being carried out in the presence of fatty acids of the formula (II): R<2>-COOH, in which R<2> can be an aliphatic hydrocarbon group with 11 to 17 carbon atoms and 0, 1 or 2 double bonds. The products contain only small amounts of chemically bound glycerin and have a low acid number. It is unnecessary to remove or neutralize the catalyst since the fatty acids are also present as esters after the transesterification reaction.

Title: Measuring width of band even when it lifts out of roller path plane - measuring positions of band edges using various camera outputs and known camera separations and positions w.r.t. roller path
Inventor: TAPPE WILHELM DR
IPC: G01B11/04
Filed: 1991-07-19
Abstract: Measuring the width of a band moving along a roller path involves using measurement cameras, each contg. a row of sensing cells individually directed at measurement points on a line transverse to the length of the roller path plane. The measurement regions of two cameras overlap the edge of the band. The band edge positions are derived from the camera separation, their distances to the roller path plane and the measured edge position values. A first measurement of each side (8,14) is performed with a central camera. A second measurement is performed from the opposite of each side w.r.t. the band's centre line (6). USE/ADVANTAGE - For accurately measuring band even when band is narrow or lifts partially or wholly out of roller path plane.

Patent DE-4207158-A1 (DE)
Inventor: BAKER BRIAN NEIL
IPC: G06F15/177
Filed: 1992-03-06
Abstract: When a memory request for exclusive access to a block of memory is granted, the starting address for that block of memory is placed in a register bank 313, thereby opening a semaphore. The starting address of a memory block of a subsequent memory access request is compared with the starting addresses corresponding to open semaphores within the register bank and access is denied if a match is found. The starting address associated with a request which is denied access is placed in a temporary buffer 32 and the request is later granted access after the corresponding open becomes closed. A request which is granted memory access to a memory block which results in an open semaphore, has exclusive access to that block of memory until the semaphore is closed. <IMAGE>

Patent DE-4214750-A1 (DE)
Inventor: BRUECKNER WERNER
IPC: H04N7/035
Filed: 1992-05-04
Abstract: When teletext data are received, usually n faulty transmitted information units are corrected on the basis of error control/information (FEC) transmitted with the teletext data, according to their correctability. In addition, the correctness of the wanted information contained in each selected and possibly corrected information block is determined on the basis of checking information (CRC) transmitted together with the teletext data. The error check for the tested information block is prematurely interrupted when the wanted information contained in an information block is recognized as faultless, on the basis of the checking information transmitted with the teletext data. In order to vary and possibly to increase the error correction capacity at the decoder side thanks to the correction capacity of the error control code predetermined at the coder side, the following steps are applied: among the information units of the concerned information block, one or several information units are gradually inverted; after each inversion step a correction attempt is made with n information units on the basis of the error control information (FEC); after each correction attempt the checking information is used to ascertain whether the correction was successful; when the correction was successful, error checking is interrupted; when a correction attempt was unsuccessful, the inverted and tentatively corrected information units are restored to their initial state.

Inventor: ASMANN HARTMUT DIPL ING
IPC: F24H9/00
Filed: 1992-06-26
Abstract: A sectional boiler for atmospheric gas burners is to be designed in such a manner so as to prevent the heating gases falling below the dew point and thus the formation of condensate. To this end, the pocket-like water chambers (3) of each boiler section (2) open with an upper corner region into a large-volume water hub (5), to which the boiler forward run (8) and the boiler return run (7) are connected. An internal mixing with a rapid rise in the return run temperature occurs in the water chambers (3).
