Abstract: A digital integrated circuit incorporates a plurality of multi-port flip-flop circuits which are interconnected by a plurality of gate circuits (3,4,8,9). A separate source of clock pulses is provided for each of the ports of the multi-port flip-flop circuits, and each clock pulse source is selectively effective to cause the multi-port flip-flop circuits to perform independent functions. During operation under one source of clock pulses, the flip-flops perform their ordinary function as D type flip-flops. During operation under another source of clock pulses, the flip-flops function as one or more shift registers in order to set the flip-flops to a predefined initial state in accordance with serial input data, and/or to provide serial output data in response to the state of the flip-flops following a preceding operation. When a further source of clock pulses is effective, a plurality of flip-flops may be connected to function as a random number generator or as a signature generator so as to perform repetitive operations such as cycling the address inputs of a ROM and providing output signals corresponding to the operation of the ROM.

Abstract: The device contains a first power controlling element containing semiconductors, for the motor drive in a first direction of torque and a second power controlling element containing semiconductors, for the motor drive in the other direction of torque. An isolating device is provided so that, at least if a particular power controlling element fails, it can be electrically isolated from the rest of the circuit and the rest of the circuit can then be connected instead to the other power controlling element. This means that down times are reduced in the case of failure of one power controlling element. …<IMAGE>…

Abstract: A nonvolatile memory bank (100) of an electronic memory and retrieval system is partitioned into at least three memory blocks (A-H), each block capable of storing an accounting program. The accounting program data is stored in duplicate with one copy of the data in one memory block (A), and a second copy of the data in a second memory block (B). The remaining memory blocks (C-H) of the partitioned memory bank are held in reserve status. The integrity of the data is preserved by comparing one data copy with the other data copy. When a difference between the two data copies is detected, a determination is made as to which data copy is the correct data copy. The data in the memory block (A-H) having the correct data is duplicated into a reserve memory block (A-H), forming a new set of data in a new memory block, which is then substituted for the memory block having the incorrect set of data.

Abstract: The invention relates to a method for amplifying enzyme activity, spcecific enzyme conjugates suitable therefor and a method for their preparation. 
     Enzyme amplification is achieved by covalently bonding enzyme to a support material via a molecular chain which is a substrate for the enzyme, then introducing a small amount of free enzyme to this system, causing release of a large amount of bound enzyme. Alternatively, complementary enzymatically inactive fragments of an active enzyme, which can recombine to form active enzyme, are covalently attached to separate support materials by a molecular chain material which is a substrate for the active enzyme, and these two fragment-support conjugates are connected in series. In a second alternative embodiment, two different active enzymes may be used. The method is suited e.g. for the S-peptide and S-protein fragments of ribonuclease S (RNaseS) which are preferably coupled to Sepharose gels, via a polycytidylic acid substrate leash. Also the released fragments recombine to give RNaseS activity. Thus this system provides more enzymatic activity from the system than is applied. 20 hours to yield activity equivalent to 1.911-g of RNase, by applying it to the S-peptide gel followed by combination of the released S-peptide with excess S-protein. Also, application of 1 ng of RNaseA to a three-stage amplification system in which each stage consists of a pair of S-peptide and S-protein gels produced cumulative amplifications of 4, 9, 52 and 25x after each to the stages, respectively. Only 1 - 2 mg amounts of each gel are used per stage in these experiments, reflecting the significant production of RNaseS activity. 
     Molecular amplification factors of -2.104 can be achieved.

Abstract: In the apparatus for continuous casting of a metal by draw­ing a solidified bar ingot through a tubular casting mold connected to an opening at the bottom of a crucible containing the melt, the tubular casting mold is protruded into the crucible in a substantial length and the cooling efficiency of the tubular casting mold and the drawing velocity of the solidified bar ingot are controlled to balance in such a manner that the temperature of the melt inside the tubular casting mold in the portion protruded into the crucible is substantially lower than the temperature of the bulk of melt to start solidification of the melt within the portion. When a bar ingot is prepared by using the apparatus and saccording to the method, great improvements can be obtained in the surface smoothness of the bar ingot and the metallographic structure of the same mainly composed of axially running columnar crystals.

Abstract: The container is preferably of double-wall construction and fabricated of high density polyethylene or other high strength material suitable for contact with foodstuffs. Polyurethane insulation may be foamed into place within the double walls during fabrication to further rigidify the structure and to reduce the melting of ice packed with fish into the container. 
     The vertical stacking strength of the containers is enhanced by the inclusion of a series of exterior vertical corrugations (1) formed in side walls (3) and end walls (5). Bottom wall (4) is strengthened by a series of exterior horizontal corrugations (6). 
     The upper portions (7) of the side walls (3) extend vertically beyond the tops (9) of the end walls (5). The bottom portions (11) of the side walls (3) are inwardly recessed a sufficient amount that the bottom portion of the container is of a reduced width dimensioned to be received between the extending upper portions (7) of the side wall (3) of a similar container container stacked vertically therebelow. 
     Preferably, the vertical dimension of the bottom portion of the container of reduced width is slightly less than the vertical dimension of the upper portions 7 of the side walls 3 extending beyond the tops 9 of said end walls 5 to allow for the thickness of container covers in the stacking of containers one above the other.

The fifth signal and one of the third and fourth signals (5b) are applied to respective frequency-to-voltage converters (9,10), the DC output voltages of which are subtracted from each other in a differential amplifier (12). The DC output voltage of the amplifier is proportional to the speed of the motor and is used to control the speed to a desired value. The converter provides a DC signal inherently free from ripple over a wide dynamic range.
