  • Patent number: 11949220
    Abstract: In a block (10) for a cable of the present disclosure, the block has a shape of a rectangular cuboid in which an upper surface (11) and a bottom surface have square shapes, the block has plural bending through holes (21) between one side surface of the rectangular cuboid and a side surface (12) neighboring the one side surface, arrangement of open ends (22) of the plural through holes in the one side surface of the rectangular cuboid is in a lattice manner, the arrangement of the open ends is in line symmetry with respect to a middle line (31) between an upper side and a bottom side of the one side surface and with respect to a middle line (32) between a lateral side and a lateral side of the one side surface, and arrangement of open ends (22) of the plural through holes in the side surface neighboring the one side surface of the rectangular cuboid is the same as the arrangement of the open ends (22) of the plural through holes in the one side surface of the rectangular cuboid.

  • Patent number: 5391299
    Abstract: The present invention provides a process for production of starch sugars, wherein starch is subjected to liquefaction and saccharification to prepare a mixture containing 10-50% by weight, based on the total solid content, of glucose and 30-50% by weight, also based on the total solid content, of maltose and the mixture is concentrated so as to have a total solid content of 40-70% by weight; and the resulting mixture is subjected to component separation using a chromatographic separator of simulated moving bed type capable of fractionating the mixture into at least three fractions, to produce a glucose fraction with a glucose purity of at least 97% by weight, a maltose fraction with a maltose purity of at least 80% by weight and a high-purity oligosaccharide fraction at a high efficiency in one operation.

  • Patent number: 4472203
    Abstract: Disclosed herein is a method for the separation of a mixed glucose-fructose solution into glucose and fructose by using a strongly acidic cation exchange resin of alkaline earth metal type and, more particularly, such method for the separation of glucose and fructose wherein said mixed glucose-fructose solution and water are supplied to and circulated through a bed of said cation exchange resin at least twice for increasing the distance between a zone of adsorption for glucose and a zone of adsorption for fructose that are formed in this way in the bed and, after such preliminary procedure, the glucose fraction and the fructose fraction of the effluent liquid are removed spotwise from the system while the remaining effluent fractions are again circulated in the order of efflux; at this time, the mixed glucose-fructose solution is injected spotwise into a portion of the liquid flow where the fructose content ratio is approximately equal to or slightly lower than that of the mixed glucose-fructose liquid, and w

  • Patent number: 4427027
    Abstract: A liquid storage chamber having a plurality of stages formed by horizontal partition plates which divide the space in the tank into a plurality of storage chambers. The partition plates have openings at their alternating ends so that the liquid supplied to the tank can flow down through the successive liquid storage chamber in a serpentine manner. The liquid storage chamber further has an opening flow setting plate having a multiplicity of liquid passage ports and disposed in each opening for making the liquid flow laminar through each opening and a storage chamber flow setting plate having a multiplicity of flow passage ports and disposed in each liquid storage chamber for making the liquid flowing horizontally in each liquid storage chamber flow in the form of a laminar flow.
