Abstract: The present invention relates to copolyethers constituted by copolymers of 7,oxa-bicyclo(2,2,1)heptane, and its alkyl deri­vatives, with one or more cycloaliphatic ethers, comprising from 2 to 4 carbon atoms in their ring. 
     These copolyethers show an anisotropic behaviour in the molten state, and therefore are endowed with liquid-crystal proper­ties.

Abstract: A distribution system for a water cooling tower (10) directs incoming hot water to particular regions of a fill assembly which are determined by the magnitude of the hot water flow rate, and struc­ture is provided for maintaining an equal head of water above all of the nozzles in current operation. During periods of relatively low flows, a weir member (76) mounted within a distribution box (38) of the system directs all of the incoming hot water to an outer distribution zone (30) which is located over four outer regions of the fill assembly. Once the hot water flow rate is increases above a certain, pre­determined value, a portion of the water spills over the weir and is conveyed to an inner distribution zone (34) located over a central region of the fill structure while the remaining portion of the water is directed toward the outer zone (30) so that water is directed to the entire horizontal area of the fill structure. Variations in the hot water flow rate either above or below the aformentioned, predeter­mined value function to raise or lower the pressure­encountered by the nozzles, but the configuration of the weir member (76), distribution box (38) and distribution conduits (40) ensures that all of the nozzles (62) in current operation continuously encounter an equal head of water without the use of valves, gates or the like.

Abstract: Nonanchorage-dependent cells are immobilized for cell culturing or the production of cell products, by contacting a medium comprising the cells with floc formed by the combination of positively and negatively charged ion exchange resins having an average particle size ranging from about 0.01 to about 1.5 micrometers. The flocs may be formed either prior to contact with the cells or may be formed in-situ in the cell-containing medium upon separate addition of the resins, preferably by first adding the positively charged resin followed by the negatively charged resin. 
     The resin floc operates as a microcarrier for the cells and the immobilized nonanchorage-dependent cells may be cultured in suspension and maintained in perfusion culture with substantially reduced cell loss and without the need for specialized filters or other equipment.

Abstract: The protection device consists of a delay arrangement (3), coupled to the electromagnetic drive (2), and an interruption switch (5), controlled by the delay arrangement (3). If the magnetic coil (20) of the electromagnetic drive (2) remains excited for longer than the period predetermined by the delay arrangement (3), the interruption switch (5) is opened by means of a changeover lever (30) and an operating element (31). In this case, the operating element (31) has such operating hysteresis with respect to the changeover lever (30) that the operating element (31) reacts delayed by the predetermined time in both the switch-off as well as the switch-on direction. This hysteresis is achieved by the changeover lever (30) having two switching arms (32, 33) which hold the operating element between them and which are arranged at such a distance from one another that the switching arm (33 or 32) which is located in each case remotely from the operating element must initially cover a no-load path s1 or s2 before the interruption switch (5) is operated. <IMAGE>

Abstract: A film magnetic head in which a soft metal magnetic film having uniaxial magnetic anisotropy is employed as a magnetic pole material, and a magnetic circuit having a magnetic path direction substantially perpendicular to the easy axis direction thereof. The magnetic head records and reproduces signals having frequencies of 1 MHz and higher. According to a first embodiment of the invention the length W of a magnetic pole film in the easy axis direction forming a magnetic path is defined as follows: 
0.2 ≦ d/W ≦ 0.3, or d/W ≦ 0.15, 
where d is the 180° magnetic domain wall distance in the magnetic pole film. Alternatively, the length W of a magnetic pole film in the easy axis direction forming a magnetic path and the uniaxial anisotropic constant Ku is defined as follows: 
50 µm ≦ W ≦ 200 µm, and 100 J/m³ ≦ Ku ≦400 J/m³, or 
700 µm ≦ W, and Ku ≦ 300 J/m³. Thus, the magnetic permeability of the magnetic core in the high frequency range is improved, and therefore the signal recording and reproducing efficiency is excellent.

Abstract: A magnetic resonance apparatus and method including a localized coil (D) disposed adjacent an examination region at least to receive magnetic resonance signals from nuclei of a subject being examined which have been induced to resonance. The localized coil (D) includes an inner conductor (30), preferably a plate (30), which defines a current path extending along the main magnetic field direction, e.g. the z-axis of the apparatus. The inner conductor (30) is mounted closely adjacent and parallel to a surface of the subject. An outer conductor (32), preferably also a plate (32), is mounted parallel to but further from the subject than the first conductor (30). A connecting member (34) interconnects first ends of the inner and outer conductors (30, 32) and is disposed perpendicular to the z-axis. A matching circuit (36) including capacitors (40) which define the resonant frequency of the coil (D) are connected adjacent second ends of the inner and outer conductor (30, 32). Because the nuclei induced to resonance within the z-axis magnetic field generate magnetic resonance components in the x-y plane, an optimal coupling is achieved to reception of the magnetic resonance signals.

Abstract: An electric discharge machining installation having a workpiece electrode, a tool electrode and a working gap therebetween is controlled in such a manner by a process regulator that at least one of the electrodes is periodically advanced by servo-control, automatically readjusting the working gap. The pressure forces arising between both electrodes (5, 15) are measured during the advance. The resulting measurement signals are related by the process regulator to technologically relevant process parameters (Vb) and to the actual advance speed (Vservo). Setting signals (Vx, Vy, Vn) for the servo-control of the electrode guiding system are derived from the result. The setting signals preferably take the vectorial signals (b1) concerning the acceleration along the path. The pressure forces can be measured by sensors (21) located at the parts of the machine stand or head where there is the highest elastic deformation while the machine is at work. With this process, electric discharge machining becomes more stable, or even for the first time possible, specially with large workpieces. By eliminating vibrations during electrode advancement the effectiveness of the electric discharge machining is improved.
