Abstract: The separation of mono- or disaccharids such as glucose or maltose from polysaccharides such as starch may be effected by passing a mixture of these saccharides through an ultra-filtration membrane whereby the glucose or maltose is separated from the starch. The ultra-filtration membranes which are employed for this purpose will comprise a cross-linked polyurethane composited on a support. As an example of the type of membrane which may be employed, an aminemodified polyepihalohydrin such as epichlorohydrin which has been cross-linked with toluene diisocyanate is composited on a polysulfone. This type of ultra-filtration membrane will permit the use of a relatively high flux with a good separation efficiency.

Abstract: The electroviscous suspension is based on a mixture of aqueous silica gel with silicone oil as the liquid phase to which a dispersant is added. The dispersant consists of amino functional or silicon-functional polysiloxanes having a molecular weight above 800. The concentration of the dispersant is from 1 to 30% by weight and preferably from 5 to 20% by weight, based on the silica gel particles. Electroviscous suspensions such as these are distinguished by the fact that they are highly compatible with elastomeric materials, non-sedimenting, non-inflammable and physiologically acceptable. In addition, they are heat- and freeze-resistant over a wide temperature range and are largely unaffected by temperature and pressure in their viscosity.

Abstract: In the packaging industry finished packing containers are frequently transported by means of chain conveyors between different machines or handling points. A reorientation of the packing containers, e.g. from a horizontal to a vertical position, may then be required. To achieve this, an arragement may be included as an integrated part on a conveyor, making use of the chain and drive element of the conveyor. The chain 1 is then led with the help of pulleys 3-6 on a path which is such that several parts 7-9 of the chain, whilst successively changing position, travel close to the packing container conveyed so thatthe latter during its advance through the arrangement is reorientated from e.g. horizontal to vertical position.

Abstract: A method and apparatus for winding field coils on internal poles of stator bodies, particularly for electric motors, have a magnet wire feeding needle or needles displaced eccentrically from the central armature axis of the stator body. The or each such feeding needle is disposed to reciprocate and partially rotate on an eccentric axis located between the central armature axis and the internal pole being wound. Due to this eccentricity, during the partial rotation of the feeding needle, the end turns of the coil are lifted above the end of the pole and laid more precisely in place. This enables the conventional winding forms to be eliminated allowing a reduction in the length of the reciprocating stroke of the feeding needle and faster winding with reduction in "snap back" effect. A further cost saving occurs from a shorter length of the end turns resulting in less wire being used.

Abstract: An aqueous effluent is supplied to a stripping column (total stripping column) from which a mixture that is rich in NH3, CO2 and H2S is withdrawn as a head product. In at least one additional stripping column the mixture is separated into a mixture which is rich in NH3 and a mixture which is rich in the sour gaes CO2 and H2S. The mixture which is rich in NH3 is scrubbed with liquid ammonia. The overhead product from the total stripping column is cooled in a condenser under a pressure of 1 to 7 bars and is thus transformed into a liquid phase to such an extent that the liquid phase contains 70 to 100% of the NH3 which has been supplied to the condenser. The liquid phase is supplied at a temperature of 30 DEG  to 90 DEG  C. to a second stripping column (NH3 stripping column), which is operated under a pressure of 1 to 4 bars and from which a gas mixture that is rich in NH3 is withdrawn as a head product. The gas mixture is scrubbed with water and ammonia and the NH3 gas which has been scrubbed is condensed.
