Abstract: PRODUCTION OF CLEAN HCN-FREE       SYNTHESIS GAS (D#76,376-F) ABSTRACT Clean HCN-free synthesis gas is produced from raw synthesis gas leaving a partial-oxidation gas generator by a continuous process comprising the steps of partial cooling, scrubbing with condensate, cooling below the dew point by indirect heat exchange preferably with a rich liquid absorbent from a downstream acid-gas-removal zone, and scrubbing with cold aqueous absorbent.  The rich HCN-containing aqueous absorbent is then safely processed, without polluting the environment. For example, the HCN-containing aqueous absorbent may be  stripped or reacted in the gas generator.  Optionally, other acid gases, if present, may be removed from the synthesis gas in said acid-gas-removal zone.                             -I-

Granted: 1982-07-13
Abstract: Abstract of the Disclosure:            A speech analyzer comprises circuits for calculating autocorrelation coefficients forwardly and backwardly with respect to time,  Reference members for the forward and the backward calculation are those successively prescribed ones of windowed samples of a signal representative of speech sound which are placed in each window period farther from a trailing and a leading end thereof, respectively.  Members to be joined to the respective reference members for forward and backward calculation of each autocorrelation coefficient are displaced therefrom by a joining interval farther from the leading and the trailing ends, respectively.          The joining interval is varied between a shortest and a longest pitch period of the speech sound stepwise by a spacing between two successive windowed samples.  One of the joining intervals for which the greatest of the autocorrelation coefficients is calculated during each window period gives a better pitch period for that period than ever obtained.  The circuits may comprise a circuit for calculating a rate of increase of an average power of the speech sound in each window period and an autocorrelator for carrying out the forward and the backward calculation when the rate is less and greater than a preselected value, respectively.          Alternatively, the circuits may comprise two autocorrelators, one for the forward calculation and the other for the backward calculation.

Abstract: Abstract of the disclosure Procedure for preparing thermogroundwood from wood chips, wherein the chip flow is conducted from a storage magazine under normal pressure through a lock feeder into a pressurized steaming chamber, where the chips stay for a few minutes and are heated to optimum temperature 100 to 125 Centigrade, and from the steaming chamber through a lock feeder to a feed means which supplies the chips into a hot grinder of enclosed design. In the procedure the steam dis-charging from the throat of the grinder against the chip flow is utilised towards heating the chips in the steaming chamber, and the steam separated from the groundwood is to the purpose of its utilization conducted. The steam utilized for heating the chips is conducted in complete counter-current fashion with regard to the chip flow, that is through the feed means, lock feeder, steaming chamber, lock feeder and magazine under normal pressure into free atmosphere, and that the grinding of the chips is carried out at a substantially higher temperature than the heating of the chips.

Title: Apparatus for the manufacture of particleboard  sections
Inventor: SEEGER GUNTER
IPC: B30B7/02
Filed: 1980-05-07
Granted: 1983-12-27
Abstract: ABSTRACT         There is described an apparatus for the manufacture of particleboard sections from cellulose based particulate material, the apparatus comprising a forming conveyor having upper and lower runs and arranged, in operation, to run continuously around first and second deflection drums with the upper run moving from the first deflection drum to the second deflection drum.          A mat carrier forwarding station located at the first deflection drum cooperates with the lower run to feed individual mat carriers with predetermined overlap onto the forming conveyor.  A scattering station scatters the particulate material in the form of a continuous mat onto the mat carriers.  A separating mechanism divides the mat onto individual mat sections located on individual mat carriers.  A transport conveyor section following the forming conveyor picks up loaded mat carriers from the forming conveyor and accelerates each mat carrier thereby to separate it from the next following mat carrier.  A storage conveyor follows the trans-port conveyor section.  A multi-storey press presses the mat sections on the mat carriers.  The apparatus further includes a vertically movable stacker loader having a number of tiers arranged between the storage conveyor and the multi-storey press.          A transporter transfers loaded mat carriers from the storage conveyor into the tiers of the stacker loader, the stacker loader being adapted to transfer loaded mat carriers located in its tiers into one side of the multi-storey press and to withdraw mat carriers from the same side of the multi-storey press.  A return conveyor located beneath the storage conveyor and driven in the opposite direction thereto returns unloaded mat carriers from the stacker loader to the mat carrier forwarding station.

Abstract: ERROR CORRECTION ON BURST CHANNELS BY SEQUENTIAL DECODING                        ABSTRACT            A sequential decoder for error correction on burst and random noise channels using convolutionally encoded data.  The de-coder interacts with a deinterleaver which time demultiplexes data from a data channel from its time multiplexed form into a predetermined transformed order.  The decoder includes a memory for storing a table of likelihood values which are derived from known error statistics about the data channel such as the probabilities of random errors and burst errors, burst error severity and burst duration.  The decoder removes an encoded subblock of data from the deinterleaver and enters it into a replica of the convolutional encoder which calculates a syndrome bit from a combination of the presently received subblock together with a given number of previous subblocks. The syndrome bit indicates if the current assumption of the path through the convolutional tree is correct.  Where there is no error in the channel, then the received sequence is a code word and the syndrome bit indicates that the correct path in the convolution tree is taken. For each received bit, an indicator bit is calculated which is a function of the difference between the current path and the received sequence.  The sequential decoder employs the syndrome bit together with burst indicator bits to calculate a table address in a table of likelihood values and error pattern values.  The likelihood value is used to update a total likelihood of error value and the error pattern value is used to change the received subblock of data.

Abstract: ABSTRACT OF THE INVENTION          "A TIME SLOT MULTIPLE CIRCUIT FOR THE SELECTIVE  ESTABLISHMENT OF CONNECTIONS IN A T.D.M. DIGITAL TELECOMMUNICATIONS SYSTEM"          Summary Incoming channel signals, which may occupy more than one time slot per t.d.m. frame, are t.d.m. multiplexed (MUX) and stored cyclically in a signal store (SPS). Connections are established between incoming and outgoing channels by means of associations between signal store addresses and outgoing channel time slots on a t.d.m. trunk line (AML). These associations are stored in a control store (STS) which is addressed cyclically by means of a counter (ZLZ). To write the associations into the control store an address register produces the associated addresses on instructions from a superordinate device. To minimise the operating time of the superordinate device when a connection involves more than one time slot per t.d.m. frame, one pair of associated addresses is arranged to produce automatically all the associated addresses required to switch signals from an incoming channel time slot to the associated outgoing channel time slot. Since the channel time slots are equi-spaced, a signal indicative of the number of transmission rate (number of time slots per frame) can be used to cause a comparator for triggering write-in into the control store to simulate more than one address per frame by disregarding one or more highest significant digits in the comparison. Alternatively the transmission rate indication may be used to substitute one or more highest significant digits or the count of a counter (ZLZ) for the corresponding digits of addresses received from the address register.
