Abstract: A device for investigating flow processes in a transparent capillary (1) has an elastically deformable tube (30) as a pump for generating the volume flow in the capillary (1). The tube (30) is filled with an incompressible liquid and connected via a conduit (24) to the capillary (1). By cyclic bending and reverse bending of the tube (30), a portion of the liquid is cyclically displaced in the tube (30) as a consequence of the corresponding cyclic variation in the internal volume of the tube (30). Due to this oscillating pumping effect, the liquid to be investigated is set in the capillary (1) into an oscillating flow. A cam disk (38) driven by a controllable gear motor (40) serves to generate the cyclic bending and reverse bending of the tube (30). The device is particularly suitable for determining the rate of aggregation of the erythrocytes in a blood sample. <IMAGE>

Abstract: Fast resource assignments, especially needed in microcellular network architectures having many fast moving subscribers (e.g.42) and high traffic volume, is provided through the use of a priority based resource assignment apparatus and procedure. Part of the communications resources in a cellular network, for example, one carrier frequency and/or one time slot, or particular code division multiple access sequences, are dedicated to the execution of the assignment procedure. Available communications resources are auctioned to cellular subscribers (42) contending for resources (e.g.,in 32) based upon a level of priority assigned to each contending subscriber. The priority level may be based on such things as the quality of service to which a customer subscribes or the particular needs of a subscriber at the time the subscriber is contending for resources, for example, the subscriber's request for resources may be prompted by a need to make a handoff (from 32 to elsewhere). The procedure involves an auction period when a determination is made regarding which of a group of contending subscribers has the highest priority level. The procedure then enters a resource assignment period where an available communications resource is actually assigned to the subscriber having the highest priority level. The auction and assignment periods are then repeated for the remaining contending subscribers until there are no longer any contending subscribers or there are no longer any available resources. Fast resource assignment could be used to increase system capacity and efficiency of spectrum utilization through the ability to perform speech activity resource sharing.

Abstract: The invention relates to a method for the catalytic hydrogenation of organic compounds in the gas phase. The circulated gas leaving the hydrogenation reactor and containing the reaction product is compressed in a compressor without prior cooling and then heats the feedstocks to reaction temperature in a superheater. The circulated gas stream is further cooled in a hot gas heat exchanger by reactants conducted in counter-current; as a result the reaction product substantially condenses out. After addition of fresh gas and feedstock, the circulated gas is again passed to the hydrogenation reactor via a purification column.

Abstract: An electrical connection element is formed by stamping a plate having a thickness. A contact surface is formed at an edge surface of an end portion of the electrical connection element. The end edge portion is bent toward both lateral sides of the plate to form the contact surface. The lateral edge portions are offset towards opposite sides of the plate, so that the width between the opposite lateral edges is about twice the thickness of the plate. This edge surface is flat and smooth. Therefore, if the round conductor of a ribbon tape contacts any portion of the contact surface, a good electrical contact is obtained. Thus, the electrical connection element for contacting the side surface of the round conductor of the ribbon wire can be produced from a thin plate material.
