IPC: F04B25/00
Filed: 1987-10-31
Abstract: The piston compressor driven by an electric motor has four cylinders (1, 2, 3, 4) connected in series on the gas side and each having a piston (7, 12, 28, 32) guided therein. Two pistons (7, 12 and 28, 32) are opposed to one another on a common axis in each case, with their piston rods (8, 13, 29) connected to one another via a yoke (9 or 30) to form a pair. The axes (5, 6) of the two pairs of pistons thus formed intersect one another and each pair of pistons is positioned in an essentially horizontal plane. Engaging in the two yokes (9, 30) of the pairs of pistons by way of a slider (11, 31) is a common crankpin (10) acting as the driving element. The gas to be compressed is fed to that side of the piston remote from the compression chamber (15) of the first compression stage via at least one intake valve (18) located in the piston (7) and the drive motor for the compressor is located beneath the horizontal planes of the two pairs of pistons (7, 12; 28, 32). <IMAGE>

Abstract: A complementary Lateral Insulated Gate Rectifier (LIGR) includes two complementary LIGR structures fabricated in adjacent surface-adjoining semiconductor wells of the same conductivity type in a semiconductor substrate. The two LIGR structures are of generally similar configuration, thus simplifying the manufacturing process, and the proposed design additionally permits the n-channel and p-channel LIGR structures to have comparable "on" resitances. The two LIGR structures, otherwise isolated by a portion of the substrate separating the two semiconductor wells, are con­nected together by a common source electrode. The resulting complementary Lateral Insulated Gate Rectifier features a compact, integrated structure in which the "on" resistances of both the n-channel and p-channel portions of the device are comparable.

Abstract: Bulk optic echelon gratings suitable for use in multi/demultiplexing optical signals carried on sets of optical fibres. The gratings can be either reflective or transmissive and may be either curved (12) with self-focusing properties or planar (26) requiring the use of auxiliary collimating opticals (24). All versions have the property of being simultaneously blazed at at least two different wavelengths whose ratio is in the range between 0.8 and 0.9. This property of the gratings enables their operation over preferred multiple wavelength bands using a limited set of fibres which are fixed in place. Preferred wavelengths at which the gratings are simultaneously blazed include 1.3 and 1.55 micrometers. Devices incorporating the gratings can be used singly or in groups in inverted tree arrangements for tandem or hierarchical multiplexing purposes.

Abstract: A high-strength spring steel which produces retained austenite less than 10 % in content by weight after quenching in steps of quenching tempering, and has high fatigue strength and relaxation resistance. The steel contains 0.30 to 0.75 % carbon, 1.0 to 4.0 % silicon, 0.5 to 1.5 % manganese, 0.1 to 2.0 % chromium, and 2.0 % or less nickel, all by weight, and iron and unavoidable impurities for the remainder. The steel further contains 0.05 to 0.5 % vanadium and/or 0.05 to 2.0 % molybdenum, as required. Preferably, the retained-austenite content is set to less than 10 % by restricting the carbon, silicon, and nickel contents as follows: 35 × C (%) + 2 × Si (%) + Ni (%) < 23 %. Preferably, moreover, the oxygen and nitrogen contents of the steel are restricted to 0.0010 % or less and 0.005 % or less, respectively. By doing this, the fatigue strength of the steel can be further improved.

Abstract: Hydrocarbons, and particularly lower molecular weight alkanes and cycloalkanes, may readily be oxidized with air or O₂ to form such products as alcohols, ketones, and the like selectively in high yields when there is employed as the catalyst a highly active azide- or nitride- activated metal coordination complex having the structure
      where M is a transition metal; " " is a ligand; and X is azide or nitride. 
     Certain dimeric forms of these catalysts may also be employed. It has also been discovered that Group IV through VIII transition metal nitrides are also effective oxidation catalysts for lower molecular weight hydrocarbons such as alkanes. The invention is also directed to certain novel azide-activated metal coordination complex catalysts per se.

Abstract: A thermally-sensitive ink ribbon, in particular a thermally- sensitive carbon ribbon, with a conventional carrier and on one side of the carrier a layer of fusible ink, where between the layer of fusible ink and the carrier there is a second layer consisting of an organic substance which does not melt during the thermal printing operation but which during the thermal printing operation adheres more strongly to the carrier than to the molten fusible ink. This thermally-sensitive ink ribbon results in markedly reduced relative gloss values for the printed symbols or letters so that there is less strain on the eye of the observer. The relative gloss values are measurable by known reflectometers.

Abstract: A measurement range is divided into a plurality of sections, a binary coded signal is generated at each division point, small section signals are generated at a predetermined interval between the binary coded signals, the binary coded signals are weighted by angles, and the small section signals are added or subtracted to or from the weighted signal to interpolate between two binary coded signals. Since the increment signals generated between the adjacent absolute signals is used as an interpolation signal between the absolute signals, the measurement accuracy is enhanced without increasing the number of elements for generating the absolute signals. The measured angle can be accurately read by adding or subtracting the increment signals to and from the weighted signal of the absolute signal.

Abstract: The described embodiment of the present invention includes a combinatorial circuit, such as a multiplexor (8). All or a portion of the input signals to the multiplexor are also provided to a transition detector (52). Upon detecting a transition, the transition detector provides a signal which temporarily suppresses the operation of the combinatorial circuit prior to a portion of the combinatorial circuit which is sensitive to glitches and/or timing errors. The delay allows time for glitches and/or timing errors to dissipate. This provides a cleaner signal for the sensitive portion to avoid the errors that the suppressed glitches and/or timing errors may cause.
