Abstract: Relates to granular slow release sources of biologically active substances, for application to or unter the surface of the soil. Useful biologically active materials include herbicides, insecticides, fungicides, nematocides, pesticides and other biocides, plant growth regulators, and the like. Particles of the biologically active material are intimately mixed with particles of a poorly soluble nitrogen source such as melamine, for example, and a binder, and made up in granular form. The form protects the biologically active material from the degradative effects of sunlight and oxygen, the leaching effect of water, the volatilization effects of wind and sun, and microbiological breakdown initiated by microorganisms.

Abstract: An improvement in a short circuiting arc welding apparatus of the type including a power supply for causing a welding current of different levels to pass through a welding wire extending at variable extension distances from a holder (14) and between the wire (10) and a workpiece (12) at a molten metal pool on the workpiece. This improvement includes control means for maintaining a generally constant wattage in the wire during the plasma boost portion of the arcing condition as the extension distance from the holder (14) changes. Further, the improvement involves controlling the plasma or arcing condition after a plasma boost by a current curve gradually decreasing from the plasma boost portion toward the background current level for the system. <IMAGE>

Abstract: A dual hybridization assay method for detecting the presence of a particular polynucleotide sequence in a test sample wherein hybridization is accomplished in a solution phase. Two soluble polynucleotide probes are employed which hybridize to mutually exclusive portions of the sequence to be detected. The first, or separation, probe comprises a reactive site for a reaction partner, preferably a binding site (e.g., biotin) for a binding substance (e.g., avidin). After hybridization, the resulting solution is contacted with an immobilized form of the reaction partner whereby dual hybrids comprising the sequence to be detected and the detection and separation probes become immobilized. The immobilized fraction is then separated and the detection probe determined in one of the separated fractions. Preferably, the detection probe is labeled such as with a specifically bindable ligand, e.g., biotin or a hapten, and is detectable by binding of a labeled binding partner, e.g., enzyme-labeled avidin or antibody. The assay method has the advantages of a dual hybridization technique plus the kinetic and manipulative advantages of a solution-phase assay.

Abstract: A device for producing alternating electric current of high frequency for power consumers such as fluorescent tubes (Ly1, Ly2) comprises a transformer with a winding (n3) connected in series with an output terminal (e) and active electronic components such as transistors (T1, T2) controlling the output current, the transistors being controlled by electric voltages produced by inductive feedback in feedback windings (n11, n12). Magnetic saturation is utilized to modify the inductive relationship in such a way that the transistors (T1, T2) cyclically change the direction of the output current. The feedback takes place in two magnetic cores (Tr1, Tr2) of the transformer, each core being provided with at least one further electric magnetization winding designated a command winding (n5, n6) as electric current is fed through the command windings to control magnetic saturation of the magnetic cores (Tr1, Tr2). As a result, combined control of the frequency and of the active electric power in the fluorescent tubes (Ly1, Ly2) is possible so that the luminous power may be controlled over a wide range while suitably high voltages can be maintained to ignite the tubes properly.

Abstract: The current frame of the picture is compared (2) block-by-block with the previous frame to identify changed picture elements (pixels). The resulting matrix is matched ('vector quantised') (4) to one of a set of standard matrices ('VQ shapes'). Only those pixels flagged by the selected VQ shape are transmitted plus a "VQ shape code". This technique is modified in that the current frame is also compared (30) with a "background" frame stored (31) at the transmitter and at the receiver. Where, for any block, all the pixels flagged by the VQ shape are indicated by the second comparison as being the same as the background, the pixels are not sent - instead a shape code plus a "copy background" instruction is transmitted.

Abstract: A method for changing the characteristic curve and/or the maximum capacity of a regulation valve, and a regula-tion valve. The valve consists of a housing (1) provided with a through flow duct (2, 2') and of a closing member (3), which is fitted inside the valve housing in the flow duct, which is shaped as a body of rotation or as a part of a body of rotation, and which is rotated by means of a turning shaft (4) extending to outside the housing. The shape of the forward edge (8) of the closing face (7) of the closing member differs from the shape of the rearward edge (9). The characteristic curve is affected by the shape of the edge (8) of the closing face of the closing member at whose side the flow opening starts being farmed when the valve is rotated from the closed position to the opened position. To change the characteristic curve and/or the maximum capacity, either one of the directions of rotation is chosen as the direction of opening of the valve.

Granted: 1996-08-06
Abstract: A binary image processing apparatus includes a first level discriminating device which has a first input terminal for receiving an image signal having a level corresponding to the density of a pixel of the image signal. A second input terminal receives a signal indicative of a discrimination level so as to allow the discrimination device to discriminate the level of the image signal according to the discrimination level into binary data. A differential device is used for obtaining a differential value of the image signal at the pixel. A second level discriminating device is used for discriminating the level of the differential value by a predetermined discrimination level. A calculating device calculates, in response to image signals in the vicinity of the pixel, an average value of density levels in the vicinity of the pixel. Finally, a discrimination level changing device supplies the average value to the second input terminal of the first level discriminating device and retains the discrimination level inputted to the second input terminal of the first level discriminating device when the differential value exceeds and is not more than the predetermined discrimination level.
