Abstract: The invention relates to a method of crystallizing lactose from a lactose-containing liquid comprising the steps of providing a lactose-containing liquid comprising less than 80% by weight total solids, providing an evaporator system that comprises a heat exchanger and an evaporation vessel, the heat exchanger comprising a tube or tubes that define a flowpath having an inlet and an outlet, heating the lactose-containing liquid in the heat exchanger to about 50 to about 90° C. such that the lactose-containing liquid passes along the flowpath by forced circulation or thermo-siphoning, concentrating the lactose-containing liquid in the evaporation vessel, to generate crystallized lactose in the lactose-containing liquid in the evaporator system.

Abstract: The present invention relates to a method of recovering lactose from a lactose-containing liquid source comprising providing a lactose-containing liquid source, crystallising the lactose in the lactose-containing liquid source to generate one or more lactose-containing liquid streams, recovering a lactose-containing extract from the one or more lactose-containing liquid streams by subjecting the one or more lactose-containing liquid streams to filtration to remove cells, proteins, polypeptides, polysaccharides, lipid, ions or salts. The method also includes processing the lactose-containing liquid streams using at least nanofiltration, ultrafiltration and/or centrifugal separation and recycling the lactose-containing extract into the lactose-containing liquid source.

Abstract: A soldering assembly has a base with a support member and at least one workpiece support member to support a workpiece. A soldering iron is removably supported by the base support member. The soldering iron includes a heating element and a heatable tip heated by the heating element. The soldering iron also has a temperature indicator that is movable, between positions, depending on the temperature of the heatable tip. Thus, the soldering iron indicates the temperature of the heatable tip to a user.

Abstract: A vending machine comprising a base (10) and a transparent lid (20) housing one or more wheel assemblies (30a-g). The lid (20) is provided with an access door (21) at a convenient height for a user and the wheels (30a-g) are independently rotatable in a user selection process to view products such as food displayed thereon. The access door (21) is releasable in response to a payment mechanism (13). Conveniently, many food products can be viewed independently, and multiple users can each independently control one of the plurality of display wheels (30a-g) giving improved user satisfaction and throughput.

Abstract: The rate of healing of a wound can be delayed or anomalous wound healing inhibited by applying an Agaricus bisporus lectin (agglutinin) to the site of the wound.

Abstract: A digital time interpolation system and method for quantizing the time-difference between two digital signals. The present invention measures the time-difference between consecutive zero crossings of a user signal and a reference oscillator. The present invention outputs interpolator data, which represents this time-difference in digital form. The present invention includes a quadrature hybrid, a synchronizer, track-and-holds (T&Hs), analog-to-digital converters (ADC), an encoding circuit, and a boundary detector. The present invention also includes a system for deskewing the recorded coarse time count and the fine time value. According to the present invention, the reference oscillator is a continuous, two-phase signal having a unique pair of output values at any given instant of its period. By using this reference oscillator, the present invention accelerates conversion. The present invention uses a novel boundary detection scheme.
