Abstract: For recovering such a bit clock, a bit clock having the frequency of the signal to be received is generated at the receiving end by means of a clock generator (TG) and a counter (Z). The position in time of the rising edge of a received pulse is evaluated in comparison with a predetermined position in time of the effective pulse edge of the bit clock generated by means of a phase evaluating logic (PAL). In the case of synchronism, the effective pulse edge is located in the centre of the pulse received in each case, considered in terms of time (bit-centre sampling). Due to non-ideal line characteristics, the period of the received pulses can deviate from the normal value. To be able to distinguish an instantaneous edge drift of a received pulse (pulse too short or too long) from an actual phase shift, the position in time of the rising and of the falling edge of each pulse is now determined. 
<??>If too short or too long a pulse deviating from the normal period is present which, however, is symmetric with respect to the predetermined position in time of the effective pulse edge of the bit clock generated, this is an instantaneous edge drift so that no phase correction is required.

Abstract: In the retarding device for the delivery end of a sheet-printing machine, a suction element (7), picking up the sheet (1) at its trailing edge, is arranged on an adjustable slide for adjustment of the format, and is guided in its movement on a loop of a path which extends through a transfer position and a release position for the sheet (1) and is, in itself, closed. This suction element (7) is connected by a four-bar transmission gear to a drive member which rotates in the same manner and is likewise arranged on the slide so that the suction element (7) is accelerated to the sheet speed prior to the transfer position and, after the sheet transfer is retarded up to the release position for the sheet. A chain wheel forming the drive member on the adjustable slide and a chain wheel of the printing machine drive are directly connected to each other by a drive chain, this drive chain passing through a chain store compensating for changes in length of the drive chain without phase displacement of the chain wheels.

Abstract: Novel fat mimetic compositions are disclosed as reduced calorie food components. These compositions comprise complex linked esters including two polyfunctional ethers or esters linked by a polycarboxy function having a common aliphatic group. These complex linked esters may be partially broken down in the body to produce digestion residues which are substantially non-digestible themselves and are sufficiently hydrophilic to enable the digestion residues to be incorporated in the normal stool. These fat mimetic compounds are useful as replacements for fats and oils for most food applications.

Abstract: A technique for reading a bar code representative of message information is stored electronically in bit-map form. The bit map is obtained by optically scanning a document carrying non-bar code information also to convert pixel information into bit information. A row is identified in the bit map which is the most likely one to pass through an area in the bit map containing bar code information. The data stored in the bit map is compared with assigned data corresponding to designated bar code components. Once such a row is identified, processing of rows above and below it in the bit map reveals whether rows more likely to agree with the coded message information can be found. Initially, a fast processing mode is selected involving processing of only a few rows to maximize processing speed in case acceptable data can be found. If acceptable bar code data is not found, then the processing is switched into a slow processing mode which involves processing of a greater number of rows. Once a row likely to contain the bar code data of interest is identified, the information it contains is converted into signals which are used for converting the coded bar code data into the message represented thereby.

Abstract: A cartesian to polar coordinate converter (10) uses a cordic magnitude circuit (14) for estimating the magnitude and angle of a vector from its known orthogonal components. The vector is described in cartesian coordinates by the complex number I + jQ where I is the real component and Q is the imaginary component. The magnitude of the vector and its angle are approximated by an iterative process of successively rotating the vector toward one of the orthogonal axes and the cordic magnitude circuit (14) is implemented in one VLSI CMOS chip. In a cordic magnitude circuit, accuracy increases in direct proportion to the number of rotations. The cordic magnitude circuit (14) achieves higher precision without the need for a larger word size. The Q processing portion of the circuit (14) takes advantage of the fact that each value of Q is reduced by one-half with each succeeding rotation after the first rotation, thereby vacating the most significant bit (MSB) position. By doubling the resultant value of Q, the MSB is refilled and the least significant bit (LSB) is vacated making room to accommodate the precision growth of one LSB associated with the next rotation. For small magnitude vectors, the I processing portion of the magnitude circuit left shifts the I and Q components by two bit positions at each rotation to accommodate two additional bits of precision in both the I and Q words.

Abstract: A memory organization having one or more groups of memory arrays is disclosed. Each array, which may be on a single chip, is provided with both a data port and a separate address port which may also serve as an alternate data port. Use of the alternate data ports permits a substan­tially smaller number of input/output circuits to be used than the number required if both the address and data ports are used. The standard data port is, however, avail­able should a higher-speed application be desired using separate address and data ports. In a single-port applica­tion, an on-chip data buffer permits the data to be sent and received through the address port in timed relation­ship with row and column address signals and without interfering with such address signals. An optional group select signal permits a large memory organization to utilize the alternate data ports of numerous groups of array chips.

Abstract: The process is based on mixing a melt with a colder liquid phase at a temperature below the catalysation point and emulsifying it therein, the melt solidifying in the form of the dispersed particles only after the emulsification. For this purpose, the melt is injected into the liquid phase to form a pre-emulsion (12) and the pre-emulsion is fine-dispersed within a residence time of 0.005 s to 0.15 s in a downstream homogenising nozzle (8) to form an emulsion (15) which then solidifies to give the finished crystal suspension. The particle size can be adjusted precisely and reproducibly by the nozzle upstream pressure during the emulsification. The process can be used especially for producing highly concentrated dispersions of high-melting organic substances.

Abstract: A method and structure for providing plurality signals which are substantially synchronous at a plurality of distant points within a system is approached from a different point of view. Rather than employing a plurality of delay means for adding various delay times to certain leads carrying the signal in question, in accordance with the teachings of this invention two separate leads (214,215) are used to route such a signal within a system. The receiving circuitry are connected to the two leads carrying the signal in opposite order, that is the first receiver (202-1) connected to the first lead (214) is the last receiver connected to the second lead (215), the second receiver (202-2) connected to the first lead (214) is the next to last receiver connected to the second lead (215), and so on. In this manner, the average of the propagation delays between the first and second leads at any given receiver is substantially equal. A locally derived signal is generated for each of the receivers based upon the two signals provided by the source (201). Each of the locally generated signals are substantially synchronized.
