Abstract: A control for an inverter operable for converting direct voltage and current to alternating voltage and current. The inverter includes a plurality of electrical valves each operable to conduct current in a single direction upon the application of a positive voltage in the forward direction and the receipt of a trigger pulse. The control provides successive trigger pulses for commutating the current between successive valves at predetermined electrical firing angles and includes a voltage-time area calculating cir­cuit for calculating the maximum permissible firing angle which will permit successful commutation. An inverter commutation failure prevention circuit is coupled to the alternating current network for detecting abnormal voltage conditions and for producting a control signal functionally related to any deviation in the alternating voltage from the expected voltage condition. The control is responsive to the control signal for reducing the electrical angles of the trigger pulses provided to the valves.

Abstract: The stereochemistry of sialylation of an acceptor saccharide to obtain an α (2-3) or α (2-6) linkage is controlled to favor the α anomer by use of an aromatic ester of the sialyl reagent. The resulting intermediate α (2-3) and α (2-6) sialylated intermediate disaccharide blocks are useful in the synthesis of antigenic substances which can be used to raise antibodies useful in diagnosis and therapy, and can themselves be used as reagents in various applications. The preparation of the tetrasaccharide antigens corresponding to the 19-9 and sialyl-X antigens characteristic of malignant tissue illustrates the application of this method.

Abstract: A liquid crystal display unit (100) is described in which a first panel of pixel elements is used to control red and green portions of a displayed image using an additive technique while a second panel, having pixels aligned with the first panel pixels, controls the blue portion of the image through subtractive techniques. The resulting display system can provide enhanced brightness, resolution and color characteristics. The display system makes use of the fact that the eye is less sensitive to blue radiation for several visual parameters. As a result of the decreased sensitivity, the second (blue) panel can operate with less stringent requirements.

Abstract: A slack adjuster has a non-rotatable fast-­threaded output member (19) threadedly engaged by a pair of nuts (20, 21), one of the nuts being a first brake-force-transmitting nut (20) clutchable to prevent rotation thereof and the other being a second adjustment nut (21) clutchable to land. Relative axial movement of these nuts relative to the output member (19) is a measure of "excessive" brake clearance and restoration of the normal spacing between these nuts serves to restore brake clearance to "normal". The nuts (20, 21) are housed in a housing (8) which is non-­rotatable but axially movable with respect to the output member (19). The first nut (20) is clutchable to a thrust member (26) resiliently loaded with a force which is overcome only by forces of the magnitude of braking forces transmitted through the slack adjuster. There is a releasable coupling (30/31) between the housing (8) and the second nut (21) which includes a splined connection (31) and which is inoperative to prevent the second nut (21) spinning on the output member (19) except when the force transmitted by the slack adjuster is sufficient to overcome the resilient loading of the thrust member (26).

Abstract: A sputter coating system utilizing a Penning type cathode. Inner and outer targets (12, 14) are concentrically oriented about an axis (32) that intersects a substrate (16) spaced from the targets. An electromagnet (26) produces a magnetic field in a region between the substrate and the targets that confines a plasma of ions relative the targets. An annular anode (30) that separates the two targets helps create an electric field that accelerates ions from the plasma to the targets where collisions between the ions and targets cause target material to sputter coat the substrate.

Abstract: A patterned metallized film (10) comprises a transparent or translucent polymeric film coated on one side with a thin coating of metal, with the metal coating and the polymeric film being bonded to each other. The metal coating has a multiplicity of fractures of different sizes distributed throughout the coating in a prescribed pattern (12) so that the reflection of light by the fractured metal coating produces a three-dimensional illusion of the pattern (12) when viewed through said polymeric film. The film may also include a layer of adhesive on the opposite side of the metal coating from the polymeric film, and a paper backing sheet on the opposite side of the adhesive layer from the metal coating. The fractures are preferably formed by heating the metallized film non-uniformly so that selected areas of the film expand and soften at a rate different from the rate at which other areas of said film expand and soften. The different rates of expansion and softening produce multiple fractures in the metal coating between the selected areas and the other areas, whereby the fractures replicate the desired pattern.

Abstract: A device for trouble-free packaging of a product, which can be influenced in its consistency by external factors, has at least one measuring container mounted pivotably in a housing. The measuring container has an inlet cross-section, through which during filling the product slides into the measuring container and which, after pivoting of the measuring container, faces, as outlet cross-section, a packaging unit to be filled. The measuring container has over its entire length a constant cross-section which is designed symmetrically in relation to a central axis which extends through the measuring container and which during filling runs approximately vertically. The measuring container has a volume which is variable with regard to its size. It has a bottom which is mounted displaceably along the central axis and which lies opposite the inlet cross-section in the direction of the product entering through this. The bottom is connected to a displacement drive which displaces it inside the measuring container. The displacement drive is guided out of the housing with a drive shaft. The drive shaft is connected to the bottom via a coupling which allows relative movements of the bottom in relation to the moving measuring container. Fastened to the bottom is a rack which runs essentially with its longitudinal axis parallel to the central axis of the measuring container and which is in engagement with a pinion fastened on the drive shaft.
