Abstract: A system determines the position of a person or other body accompanied by a radio signal transmitter which constantly generates a radio signal of a predetermined frequency or is adapted to generate such a radio signal when the user manually operates the transmitter should an emergency arise. The system includes two different antenna networks, one comprising a plurality of non-directional antennas disposed substantially evenly over a specific area, always ready to receive the radio signal which will or may be transmitted from anywhere in the area, and the other comprising directional antennas mounted at several points in the area. In response to the radio signal being monitored by one or more of non-directional antennas, at least two of directional antennas come into operation and two different directions in which the respective directional antennas show the maximum field strength are detected with field strength meters attached thereto, which makes it possible to determine an exact position of the signal source by triangular surveying. A computer may be a help to operation of the system.

A test device may be employed in conjunction with the capillary inoculator and includes discrete test sites which are aligned with the ends of the respective projections. Each of the test sites may be provided with an absorbent material such as a cellulose disk. A dry reagent may be deposited upon each disk so that the inoculum may be analyzed by testing equipment or by visual observation. A method is provided which includes the steps of filling the capillaries, aligning the capillaries with the test sites within the test device, and depositing the liquid inoculum on the respective test sites through wicking action or other procedures.

Abstract: An impeller with semiaxial blading and a vertical axis of rotation is rotatably arranged in a well-shaped thrust housing. The drive for the impeller is inserted into the thrust housing from above through a cover plate, and the thrust housing is closed at the bottom by a base plate which has a water inlet, arranged concentrically in the centre, for the axial flow of water against the impeller and at least one water outlet inclined at a slight angle. Arranged between the discharge end of the delivery passages of the impeller and the at least one water outlet is a baffle apparatus in which the flow energy of the water delivered by the impeller is converted to the greatest possible extent into thrust energy. The base plate (3) is structurally separate from the well-shaped thrust housing (1) and its cover plate (27), and the thrust housing is integrated in the supporting structure (42) of the ship as an integral component of it. The base plate together with the water inlet (4) integrated in it and the at least one water outlet (11) can be continuously rotated about the longitudinal axis of the thrust housing in both peripheral directions.

Abstract: A process is to be specified for preparing solutions from basic aluminium chloride with molar ratios Al/Cl in the range between 0.33 and 0.66, in which no chloride-containing aluminium hydroxides are precipitated prematurely, but high aluminium contents and high Al/Cl molar ratios are achieved within short reaction times. This is effected according to the invention by reacting an aluminium-containing solid with an acidic, chloride-containing, aqueous solution, the reaction being carried out at a temperature between 140 and 250 DEG C and a residence time of from 2 to 60 minutes. The process according to the invention permits reprocessing of large quantities of industrial hydrochloric residual solutions into valuable products, said reprocessing being applicable, for example, to water purification, especially in waste-water purification of industrial and municipal waste waters.

Abstract: A bipolar diathermal instrument is fed a pulsed RF current in order to carry out an incision optimally in capsulotomy. The working pulse width can be continuously varied between 3 ms and 11 ms, resulting in a pause of 30 ms and 22 ms, respectively. This pause is sufficient to cool the instrument tip, which is flushed with sodium chloride, so that no damage to the adjacent tissue can occur. The pulse repetition frequency is approximately 15 Hz. The equipment required for this purpose comprises a pulse width control (31) and an RF oscillator (30). The RF current is clocked by pulses from the control (31) by means of an AND gate (35). An amplifier (40) feeds the handset (21) of the diathermal instrument via a transformer (46), thus ensuring the desired operation free from earth potential. <IMAGE>
