Abstract: Graft copolymers and processes for the preparation thereof are provided. The copolymers comprise a base polymer having grafted thereto a monomeric 2-alkenyl azlactone. The surface properties of the graft copolymers can be modified by binding thereto nucleophilic reagents comprising further functional groups with desired properties. Further, the amount of azlactone available at the surface of a graft copolymer for binding to such nucleophilic reagents can be controlled by selecting a surface against which the graft copolymer is formed. The graft copolymers exhibit desirable thermoplastic, melt flow, and adhesion properties and are particularly useful for immobilizing proteins. Methods of immunoassay based on the immobilization of proteins are also disclosed. Another utility of the graft copolymers involves the compatibilizing of immiscible polymer blends.

Abstract: The present invention provides an ultra-precise positioning system for positioning of a moving part (4), in which a moving part (4) and a fixed part (9) have contact with only a rolling guide (8) to which contact pressure is applied, and it is driven by non-contact motors (1), (2) and (3); a position measuring means (5) is install­ed to measure the position of the moving part (4), a posit­ion reference generating means (10) to generate the position reference of the moving part, and the positioning control systems (11) and (12) to control the position of the moving part by comparing the measured position to the position reference. The positioning control system consists of three positioning control systems utilizing the following three dynamics of the rolling guide: the region I having reversible and elastic spring characteristics of the roll­ing guide, the region II where the displacement of the moving part depends upon the force, and the region III where friction force is saturated and normal rolling takes place. The high velocity and long stroke coarse positioning is performed by the positioning control system in the region III, and the fine positioning of nanometer order is perform­ed by the positioning control system in regions I and II.

Abstract: Extraneous matter in raw cotton in the form of other fibres, tapes or sheeting cannot be completely removed by customary methods. Some of the foreign particles get as far as the card sliver and then cause yarn breakages and fabric faults and hence relatively high costs. The method described makes it possible to detect such foreign matter in web, sliver or yarn. To this end the fibre material (1) is illuminated with polychromatic light. At least two frequencies of the reflected light are selectively detected and compared. The output signal of the difference circuit (7) used for this purpose is kept constant by a closed loop control circuit (8,9'). As a consequence of a large acting time constant, foreign fibres produce a spontaneous change in the output signal if they differ in colour from the raw cotton. The apparatus described makes it possible, together with a yarn cleaner, to remove foreign fibres whose colour differs from that of raw cotton in the course of rewinding.

Der erste Integrator erzeugt ein Outputsignal in Entsprechung des Integrals der Differenz zwischen einem ersten Positionssignal, welches die gewünschte Position der Antriebswelle anzeigt, und einem zweiten Positionssignal, welches die tatsächliche Position der Antriebswelle anzeigt. Der zweite Integrator reagiert auf das Outputsignal von dem ersten Integrator, um ein Steuersignal zu erzeugen. Eine Steuerungsanordnung reagiert auf das Steuersignal von dem zweiten Integrator, um die Antriebswelle zu beschleunigen. Während der Beschleunigung der Antriebswelle wird die Differenz zwischen dem ersten und dem zweiten Positionssignal auf einen Nullwert reduziert. <IMAGE>

Abstract: Gaseous hydrocarbons, which are thermocatalytically stripped from natural gas/petroleum parent rocks in subsiding sediment basins or which penetrate the seal of natural gas/petroleum deposits, reach the earth's surface in trace concentration within a geologically short time. The transported hydrocarbon gases transfer information about the hydrocarbon potential, the organic facies and the stage of maturity of the stripping parent rock or about the characteristics of a deposit to the surface. According to the invention, this circumstance is utilised for making statements regarding the prospectivity of the underlying rock by means of measurements at the surface. The molecular and isotopic composition of the trace gases is measured and, allowing for the changes caused by the transport, the abovementioned information about the natural gas-/petroleum-geological state in the underlying rock is derived therefrom. The isotopic changes in the methane during the migration to the surface are quantified. The relationship of the original gas parameters, reconstructed in this way, from parent rock and deposit up to their present geological state and potential - that is to say the prospectivity - of the basin is derived. This makes it possible to provide, before drilling, data about the hydrocarbon potential which is available for filling a certain structure or regionally in a sediment basin, and about lateral changes thereof. Under special geological conditions, the existence of a deposit in the underlying rock can be directly proved, and lateral changes in the effectiveness of stripping can be recognised. Application of the method is therefore suitable for a considerable reduction in the risk of development prospects for crude oil and natural gas.
