Abstract: The principles of invention consists in a two-step process of immobilization of biologically efficient compounds where the biologically efficient compounds are bonded to a macroporous polymeric carrier containing reactive functional groups from an aqueous solution by a hydrolytically stable linkage. The process is characterized in the first step by a hydrophobic adsorption of the biologically efficient compounds on a macroporous matrix of the carrier and to an increase of their concentration on the solid surface. In the second step, the reaction takes place with the reactive functional groups of carrier and a covalent linkage is formed. The hydrophobic adsorption of compounds determined for immobilization is achieved by addition of inorganic salts in concentration 0.5 to 3.0 mol/1. 
<??>The invention can be utilized in the preparation of enzymatic catalysts for transformations of compounds and in the preparation of specific sorbents for both the analytical and preparative affinity chromatography. These methods are used in biotechnology, chemical and clinical analysis, food industry, pharmacology and clinical therapy.

Abstract: An area-security system comprises a transmitting/receiving strip arranged along one side of an area to be secured and a reflection strip arranged along the other side. The transmitting/receiving strip is divided into transmitting regions and receiving regions, the transmitting regions consisting of a plurality of transmitting elements which are arranged alongside of each other and which are combined in at least two groups, and the receiving regions also consisting of a plurality of receiving elements which are arranged alongside of each other and are also combined in at least two groups. Modulated light from the transmitting elements strikes the receiving regions after being reflected by the reflection strip. A control circuit determines association of different groups of receiving elements with the individual groups of transmitting elements. A multi-channel evaluation, under the synchronizing control of a control circuit, evaluates the signals on the basis of various factors. The area-security system is particularly suitable for penetration-security or for entry-security application, and for the securing or control of machines.

Abstract: In a claw coupling with a synchronization locking device for gear changing, a synchronization component (1) and a gearwheel (2) rotating at different speeds are locked together and synchronized by means of an annular sleeve (3) sliding in an axial direction. Internal teeth (31) on the sliding sleeve (3) mesh with corresponding outer teeth (11, 12) in the synchronization component (1) and gearwheel (2). Locking and/or pressure bolts (4) located between the synchronization component (1) and the sliding sleeve (3) engage in the non-coupled state with a recess (32) on the inner surface of the sliding sleeve (3) and have pressure surfaces (41) which co-operate with pressure surfaces (51) on a synchronization ring (5, 6) fitted between the synchronization body (1) and the gearwheel (2). At least two synchronization rings (5, 50; 6, 60) are connected together by entrainment devices (52, 520; 62, 620) and are in a drive relationship with the synchronization body (1) in both circumferential directions, with a peripheral clearance. Friction surfaces (24) associated with the gearwheel (2) form, with friction surfaces (53, 63) of the synchronization rings, several friction-type couplings. When no synchronization is present the axial movement of the sliding sleeve (3) is locked by arresting surfaces (37, 66). A coupling component (7) is fitted with a lateral clearance in a recess (12) in the synchronization component (1) and is connected to at least two synchronization rings (5, 50; 6, 60) connected together. As a result of the coupling of the two superimposed synchronization rings (5, 50) the frictional movement of the lower synchronization ring (50, 60) helps increase the locking moment, so that the tips of the locking teeth can be made narrower and unlocking is facilitated.

Abstract: In the substantially radially extending compartments of a cell wheel or drum of a processing apparatus for processing printed products, there are inserted removable divider or partition walls. The removable divider or partition walls divide each of the compartments into two feed channels. These divider or partition walls terminate at a predetermined distance or spacing from the floor of the compartments. Feed structure, such as grippers for advancing the printed products are arranged in the region of the floor of each compartment and such feed structure commonly coacts with both feed channels. A printed product is inserted into each feed channel. Both printed products are conjointly advanced in the longitudinal direction of the compartments by the related product feed structure and these products are simultaneously opened and furnished with inserts. The opening of the printed products and the stuffing of inserts is done separately. The divider or partition walls can be removed without difficulty, whereby the number of reception spaces or regions (feed channels) for printed products is reduced by one half.
