The invention relates to a new method of preparing lactulose by basic isomerisation of lactose. According to the invention the reaction mixture is treated with hydrogen peroxide or sodium chlorite to obtain lactulose of an acceptable colour for a pharmaceutical product. Preferably 0.5 - 5 g of hydrogen peroxide are used per kg of lactose. 1H2O.

An optical head includes a light source emitting a light beam which is transmitted via two reflectors to a lens which focusses it on to an optical storage medium, for example a magnetooptic storage disc. The reflectors are supported on a swing arm which is mounted to rotate. Light reflected from the storage medium is returned via the reflectors and a splitting prism to a detector producing an ele...

A drum-shaped wind wheel is described, which is provided with a cylindrical tube 1, arranged coaxially with the axis of rotation of the wind wheel, both ends of which tube have circular end plates 2 and 3, vanes 6, 7, 8 and 9 having an obliquely streamlined profile and being supported with limited capacity for inclination in proximity to the edge of the two end plates 2 and 3 on moveable shafts 10...

The present invention concerns a receptacle for the storage of fluid under pressure and comprising an internal casing with axis X,X' and having one central cylindrical section and two extremity sections, an armouring encompassing said casing and leaving clear at the convex extremity section a cap centered on axis X,X'. According to the invention, the outer contour (8) of said convex extremity sect...

An improved fibrinolytic compsn. comprises (a) a fibrinolytic enzyme (I) and (b) a surface-active copolymer of formula HO-(C2H4O)b(C3H6O)a(C2H4O)bH (II) (where a is an integer such that the hydrophobe represented by (C3H6O) has a mol. wt. of 950-4000 and b is an integer such that the hydrophile portion represented by (C2H4O) constitutes 50-90 wt.% of the cpd.). (I) is e.g. tissue plasminogen activ...

The refuse sack trolley (1) has a frame (9) to support the sacks (2). The lift frame (14) on the lifting equipment (10) is articulately connected to the pivotable frame (13) for lateral pivoting movement between an extending connecting position (I) to engage the trolley and one where it is withdrawn for protection and/or transport.

For the purpose of counteracting the formation of ice on various surfaces, use is made of a liquid product composition which consists of a hardenable polymer which contains a reinforcement or filling of an elastic, solid material. A two-component urethane is used as the hardenable polymer, and natural rubber or synthetic rubber in the form of spherical particles or fibres is used as the solid mate...

Several power transistors are fitted on the hybrid segment via gate connections, each of which is reinforced by an epoxy layer. Each segment is insulated by insulators positioned between the base element and a bottom element. All segments are provided with end elements for drain and source connection. These end elements are in turn connected to a central bolt. A lock arrangement comprising insulat...

The clamp has two assymetrical halves, an inner half with a short pin in its end, and an outer half in which is a supporting and protective hole for the pin. A lock stirrup maintains the two halves joined together. To secure the wallet in a pocket, the clamp pin is firstly pushed through the wallet at the point where it is thinnest, and then through the cloth of the pocket. - The outer clamp half ...

The optical storage medium which can be recorded and distinguished optically comprises a film having two stable crystalline state differing in crystal structure and optical properties selectively obtainable by optical irradiation. Specific optical properties are transmittance and reflectance. A preferencial film is an eutectic mixture, especially In-Sb (42), Tl-Bi, Ga-Bi, In-As, In-Bi, Ga-Sb and...

A chain of flexible material is entrained in a loop extending between each of several lever assemblies' speed change devices and around sprockets, enabling pedal levers to execute see-saw motion as the levers are oscillated upwardly and downwardly by force applied to the pedals.
