Abstract: A method for continuous preparation of highly pure monoglyceride comprises the steps of esterifying fatty acid dissolved in a nonpolar solvent at the interface between the nonpolar solvent phase and a polar solvent phase containing glycerol, water and dispersed lipase, the polar phase being located below the nonpolar phase, continuously taking out the nonpolar solvent phase, cooling the taken out phase to isolate the resulting monoglyceride by precipitation, and bringing back the remaining solution to the esterification system. 
     By this method, monoglycerides having high purity can be produced continuously and at low cost, and further monoglycerides of straight-chained fatty acids can preferentially obtained even though the fatty acids used contain branched fatty acids.

Abstract: A multi-bit overlapped scanning multiplication system assembles modified partial products in a reduced, non-rectangular banded matrix. The rows of the matrix except for the first and last, are extended with bands of encoded extensions of limited length at the right and left ends of the partial product terms. The width of the significant bits of each partial product term is equal to q-1+S-2, where q is the width of the significant bits plus sign of the multiplicand and S is the number of bits which are overlapped scanned. Each partial product term is shifted S-1 bits from adjacent terms and is banded by encoded extensions to the terms. S-1 bits of encode are placed to the right of every terms except the last, the encode being based on the sign of the next partial product term; and S-1 bits of encoded sign extension are placed to the left of every term except the first, which has no sign extension, and last, to the left of which is placed an S bit encode. The bits of negative partial product terms are inverted, and a "hot 1" is encoded in the right extension in the previous row. The first bit of the multiplier is forced to zero so that the first partial product term is always positive or zero. Carry save adder trees are used to reduce each column of the matrix to two terms. When inputs to a carry save adder are known, the logic of the carry save adder is simplified to save chip space.

Abstract: The central unit (14) comprises a distortion sampler (16) including a spectral sound analyser and a memory for recording the digital data of at least one reference sound. The central unit by means of the analyser analyses a sequence of such sounds which are received by way of the telephone line (11, 13) and makes a comparison with the recorded data. It thus produces a measurement of the frequency response of the transmission, that is to say distortion and attenuation introduced by the telephone connection, in accordance with the various frequencies. The data of that measurement are used by the central unit (14) to compensate for the signals which are successively received by way of the activated telephone connection. The system comprises a portable acoustic device (35) in which the digital data of the reference sound are recorded. That device may be connected to any telephone apparatus (12) of the network and comprises a manual control for triggering transmission to the central unit (14) of the sequence of reference sounds after the telephone connection has been established by means of the telephone apparatus (12). The portable device (35) may also have a recording of a code for identifying the user, for example, for use in a vocal postal system. In addition in a system in which the central unit (14) comprises a voice recognition device (17) the portable device (35) may have the recording of a series of phonetic prototypes, or phonemes, which are specific to the particular user, to be transferred to the central unit to improve the quality of recognition of the speech transmitted thereby. Alternatively the phonemes of different users may be recorded in a memory of thee central unit (14) and be selected thereby on the basis of identification code.

Abstract: The digital communication switching system consisting of several exchanges should be able to exchange all types of useful and signalling information items in a standard form between transmitter and receiver. It should be possible to connect the individual exchanges to one another via standard interfaces. The line element groups consisting within an exchange, which are in each case predominantly connected to line elements of the same category, are in each case connected via a standard digital interface to a parallel bus operating without fixed time slot allocation, over which bus the entire information exchange takes place. In addition, at least one serial bus, also operating without fixed time slot allocation, leading to other exchanges of the communication switching system is provided which is connected to the parallel bus system via a serial bus interface. The parallel bus system and also the serial bus have the characteristics of switching matrices because the line elements are directly addressed during the exchange of similar information packets. The digital communication switching system can be advantageously used wherever exchanges are to be connected together to form a combination of exchanges. The exchanges, which are in each case independently functional, can also be connected together as parts of a large exchange, particularly a private branch exchange. <IMAGE>

Abstract: Hazardous waste is formed into non-hazardous non-leaching aggregate by introducing the material to a rotary kiln (10) where the large solids are at least partially combusted to form a primary aggregate. Gaseous combustion by-products and waste fines from the waste materials are introduced into at least one oxidizer (26, 56) operating at a temperature in the range of from about 1800° to 2500°F. Under such conditions, some of the waste fines are melted to form a slag-like material that is cooled to form the non-hazardous aggregate. The portion of the material in the ox­idizer that is not melted, is cooled, neutralized and subjected to a solid gas separation. The solid is reintroduced to the ox­idizer with the primary aggregate where they are either melted or entrained within the molten material and become an integral part of the non-hazardous aggregate.
