  • Patent number: 4861382
    Abstract: A continuous process for the crystallization of fructose from an aqueous fructose syrup containing at least 90% by weight fructose on a dry solids basis, in which the syrup at a total solids content of at least 95% by weight is rapidly and thoroughly mixed with seed, at a temperature of 55.degree.-75.degree. e.g for up to 2.5 minutes; is then deposited onto a surface where it is allowed to crystallize under quiescent conditions at a temperature of about 50.degree.-70.degree., until a solid cake is formed; and is the comminuted to provide a free-flowing granular product which can be further dried.The process provides a particulate product in the form of crystals in a glossy matrix, in which 95% of the crystals have a particle size of less than 20 microns, the overall degree of crystallinity is greater than 70%, the bulk density is less than 0.65 and which is completely free of organic solvent residues. Other food ingredients may be added simultaneously with the seed.

  • Patent number: 4835924
    Abstract: A self-gridding flooring system and method for installing the same in which various disclosed embodiments of gridding members are used for contacting and spacing the panels from one another as they are installed, thereby eliminating the necessity of measuring and establishing a gridding in advance of the installation of the panels. The method and apparatus provides a way of assuring that the installed panels are sufficiently spaced apart that any one or more of the panels may be removed and replaced by any geometrically similar replacement panel or panels having the same nominal dimensions and the same tolerance ranges without interference between the replacement panels and the previously-installed panels contiguous thereto. The invention is suitable for use with panels having legs and panels not having legs, and further is suitable for panels having any overall configuration, including rectangular panels and triangular panels.

  • Patent number: 4826962
    Abstract: The novel chlorinated sugar O-.alpha.-D-6-chloro-6-deoxygalactopyranosyl-(1.fwdarw.6)-.alpha.-D-4-chlo ro-4-deoxygalactopyranosyl-(1.fwdarw.2)-.beta.-D-1, 6-dichloro-1, 6-dideoxyfructofuranoside (TCR) can be used to prepare sucralose by incubating the TCR in solution in the presence of an enzyme serving to remove the 6-chloro-6-deoxygalactosyl moiety from the 6-position, especially an enzyme derived from a strain of Mortierella vinacea, Circinella muscae or Aspergillus niger. TCR is prepared by treating raffinose with thionyl chloride in the presence of triphenylphosphine oxide.

  • Patent number: 4741795
    Abstract: A method of lining pipes comprises the steps of laying along the pipe (56) hoses (63) filled with constituent components of a settable resinous lining composition, axially slitting the hoses, conveying the constituent components to a mixing chamber (65), and centrifugally impelling the mixed lining composition against the wall of the pipe (56). A lining apparatus (50) for carrying out the method is advanced along the pipe (56) and comprises delivery tubes (62) with slitting blades (70) at their leading ends which are pushed through the holes (63) and which communicate with a mixing chamber (65) which, in turn, is open to a centrifugal impeller (57) of a lining machine. The slit and emptied hoses (63) may be left in situ in the pipe (56) or removed therefrom in advance of the lining apparatus (50). A trowelling arrangement using a thin-walled, flexible tube (112) of, for example, a cellulose polymer and a conical trowel (112) is employed to smooth the pipe lining.

  • Patent number: 4710231
    Abstract: Solid fructose, typically with a bulk density of less than 0.65 g/ml and in the form of particles of agglomerated microcrystals of anhydrous fructose in which all the crystals have a maximum dimension of less than 50 microns, can be produced by dispersing a high Brix fructose syrup at very high shear in an alcoholic medium, the alcoholic medium being one in which fructose is 1 to 10 wt % soluble at the temperature at which the syrup is dispersed in the alcoholic medium.

  • Patent number: 4640717
    Abstract: Sugar (sucrose or glucose) is crystallized by passing a hot supersaturated syrup to a continuous screw extruder such that progressive nucleation of the syrup is induced during a mean residence time of below 25 seconds and then discharging the nucleated syrup onto a surface, e.g. a conveyor belt, to crystallise without agitation.

  • Patent number: 4617269
    Abstract: A process for preparing a fructoside, especially a fructosyl disaccharide, comprises reacting a fructosyl saccharide such as sucrose or raffinose with an alcohol or aldose in the presence of a fructosyl-transferase, especially one derived from B. subtilis NCIB 11811, 11872 or 11873. In particular, aldose is a compound of the formula ##STR1## in which A represents a hydrogen atom or the group CH.sub.2 X, where X represents a hydrogen atom or an alkoxy group, and the fructosyl disaccharide so formed is halogenated to provide a halosucrose or halogalactosucrose sweetener.

  • Patent number: 4612373
    Abstract: Compounds of the general formula: ##STR1## (in which X represents a hydrogen atom or an alkoxy or arylalkoxy group) are new compounds; those where X represents a hydrogen atom or a methoxy group are potent sweeteners while those with a cleavable 6-ether group are key intermediates in the preparation of 4,1',6'-trichloro-4,1',6'-trideoxygalactosucrose (TGS). They are prepared by chlorinating a sucrose 6-ether, by etherifying a suitably protected derivative of TGS or, in the case where X represents hydrogen, by debromination of 6-bromo-4,1',6'-trichloro-4,6,1',6'-tetradeoxygalactosucrose.
