Filed: 1986-02-19
Abstract: A bidirectional optical multiplexer and demultiplexer, called Bomudex, is described. It can be used as passive out-of-area device in a bidirectional subscriber line system. The bidirectional wavelength-division multiplex signal transmitted on a first optical fibre 1 is divided into individual signals by wavelength-selective means, depending on the direction of transmission, and assembled from single signals. One single signal per direction of transmission is in each case transmitted by further optical fibres 5. Three illustrative embodiments are described which are distinguished by the wavelength-selective means used (filter, grating and wavelength-selective fibre coupler). <IMAGE>

Abstract: The present invention is directed to a method for removing organic substances from aluminate liquors of the Bayer process. The method comprises the steps of contacting the liquor with an oxygen containing gas under elevated pressure in the presence of metallic ions acting as a catalyst to oxidize the organic substances, precipitating the metallic ions jointly with aluminum hydroxide, separating the precipitate from the oxidized liquor and recycling the precipitated aluminum hydroxide containing the metallic ions into the oxidation step as a catalyst carrier.

Abstract: A method of improving the functions of the surface of alloy steel (5) by means of the irradiation of a laser beam is disclosed. In this method, the alloy steel (5) is kept in contact with the aqueous solution (4) of oxidizing acid or salt thereof and the irradiation of a laser beam is applied on the surface of the alloy steel through the aqueous solution, thereby concentrating an alloy component on the surface of the alloy steel. The aqueous solution (4) contains at least one selected from the group consisting of nitric acid or nitrate, chromic acid or chromate, or permanganic acid or permanganate. In addition, the irradiation of the laser beam is applied so as to depict a given pattern on the surface, and a computer (32) controls the shape and the size of the beam, the position of the alloy steel, and the like. The present method enables the improvement of a surface function of the alloy steel by providing various kinds of color-patterns.

Abstract: A steer angle adjusting apparatus for a vehicle is arranged such that the respective steer angles of right and left steered wheels of the vehicle which are steered by a steering device are adjusted independently of each other by a steer angle adjusting mechanism. A running condition of the vehicle is detected by running condition detectors, and the steer angle adjusting mechanism is controlled by a controller in accordance with the detected running condition. Accordingly, the steering stability is improved irrespective of the running condition of the vehicle.

Abstract: The reinforcing element has longitudinal bars (1-3) which are connected to hoop-shaped spacer bars (6). The longitudinal bars (2, 3) located near the ends of the spacer bars are at a distance from the outermost end of the respective legs, so that the respective end portions of the legs can be covered with a rust-proof covering (8). This distance also ensures that the longitudinal bars (1-3) are reliably covered with the concrete. This reinforcing element thus constitutes a three-dimensional reinforcement. There is therefore no longer any need, during assembly, to arrange individual layers of longitudinal bars for a particular surface reinforcement and to fix these relative to one another via spacer pieces. The installation time for the reinforcement is consequently reduced. <IMAGE>

Abstract: Randomly generated artificial perturbation signals are acoustically coupled to fluid jets to artificially stimulate droplet formation at a rate which varies. Such changes . minimize the discernible effects of anomalies in droplet- formation (e.g. along the cross-machine dimension of an extended orifice array) caused by standing acoustic waves or other phenomena. A relatively low frequency bandwidth- limited square wave with randomly occurring transitions has a controlled amplitude related to a desired magnitude of deviation in the rate of droplet stimulation. This first random signal is used, in the exemplary embodiment, to control the frequency of a frequency modulated oscillator having a relatively higher mean frequency related to the naturally expected rate of droplet formation. As a result, piezoelectric crystal drive furnished by the oscillator randomly varies between upper and lower frequency limits. Provision is also made to ensure that such transition between upper and lower frequency limits is accomplished in a controlled and relatively gradual manner.

Abstract: An automated vertical photo densitometer for reading solutions contained in microwell plates. The densitometer utilizes an optical system for minimizing the optical effect of a meniscus on the fluid sample. The invention also discloses a method for determining a centrally located position of a microwell beneath an interrogating beam of light by controlling the size of the light beam and by stepping the well through the beam. A measurement of the light intensity received by a detector is taken at each step. A maximum light intensity value is selected as corresponding to a well position wherein a central area of the fluid sample is substantially within the interrogating beam.
