Abstract: A high power, high frequency attenuator which provides attenuation steps which are switchable at very high speed, the attenuator implementing a method by which the input signal is split into two separate signals which are then subjected to impedance mismatches in the signal path, so that a portion of the split signals are reflected back to the signal splitter for dissipation there and the remaining portions of the split signal are transmitted to a summing circuit for recombination and output. The value of mismatch imposed determines the degree of attenuation obtained. The splitting of the signal reduces the stress upon the mismatched components as well as permits high switching speeds of the mismatches in and out of the circuit. In one embodiment of the invention directional couplers are used to provide the signal splitting and recombination functions, with the result that high isolation is achieved between the input port and the reflected signal caused by the mismatches.

Abstract: The invention relates to a process for the preparation of methanol by converting a lower hydrocarbon or mixture of lower hydrocarbons to a first gas mixture containing CO and H2 and converting this first gas mixture to methanol at elevated temperature and increased pressure in the presence of a suitable catalyst. In order to obtain low energy requirements this process is characterized in that said lower hydrocarbon or mixture of lower hydrocarbons is converted in a first reactor to said first gas mixture consisitng substantially of CO, CO2 and H2, by partial oxidation thereof with oxygen and optionally water, at a reactor outlet temperature of between 800 and 1500 DEG C and a pressure of between 40 and 150 bar, that said first gas mixture is supplied to a second reactor where it is converted to a second gas mixture containing methanol at a temperature of between 240 and 320 DEG C and a pressure of between 40 and 150 bar in the presence of a suitable catalyst, that a third gas mixture consisting of the non converted gaseous components is separated from said second gas mixture by cooling, that from this third gas mixture prior to recirculation to the reactor carbon dioxide is removed in an amount that the molal ratio H2(2CO + 3CO2) in the combined said first gas mixture and the depleted third gas mixture is at least 0.90, which combined mixture is to be supplied to said second reactor, that the crude methanol, obtained by said cooling of said second gas mixture is expanded to a lower pressure, and purified and that the energy released during said partial oxidation and the conversion of said combined gas mixture to said methanol containing third gas mixture is at least in part used for the generation of steam.

Abstract: In the production of non-oriented electrical steel sheets, it has been attempted to decrese the watt loss, e.g. by adding Sn into silicon steels, but in such a case the relationship between the watt loss and magnetic flux density falls within the curves 1 and 1 min in Fig. 1. The addition of boron is therefore unsatisfactory for meeting the recent demands, for improving the magnetic properties of a non-oriented electrical steel sheet over those indicated by the curve 3. In the present invention, the combined addition Sn with B and/or sol. Al results in development of (110) and (100) textures which are desirable for the magnetic properties. A non-oriented electrical steel sheet according to the present invention, contains 0.015% of C at the highest, from 0.3 to 2.0% of Si, from 0.005 to 0.10% of sol. Al, from 0.02% to 0.20% of Sn, 0.007% of N at the highest, and 0.005% of B at the highest, the weight ratio of B content/N content being from 0.5 to 1.5, said non-oriented electrical sheet being produced by a process comprising an annealing of a hot-rolled steel strip. Instead of B, an appreciable amount of sol. Al may be contained in said sheet, when Mn content is from more than 1.0% to 1.5%.

Abstract: The dust collector is for removing dust from a gas. The contaminated gas is drawn into a filter chamber (8) where it passes through hollow, flat, box-like, cloth covered filter members (7) and into gas passages (9 min ). Dust is separated from the gas by the filter members and at least some of this dust builds up on the outer surfaces of the filter members thereby gradually reducing their efficiency. To dislodge this built up dust compressed air is introduced into the filter members through outlets (11) thereof from compressed air outlets (12) disposed in the gas passages. In order to make this possible with a small capacity compressor, an outlet (14) in the gas passage is closed and an atmospheric air inlet (15) in the gas passage is opened by a piston and cylinder unit (16, 17) which operates respective valves (18, 19) when the compressed air is introduced into associated filter members. Only those filter members associated with one of the gas passages are cleaned at a time so that the collector can continue with its dust removal operation during this cleaning process.

Abstract: A releasable locking device comprises a tubular housing (180) having a pair of rotary pawls (182) mounted therein. The angular position of the pawls are controlled by spring-loaded balls (183). A line (179) passing through the housing has a collar (184) thereon which latches with the pawls when the collar is brought into engagement therewith, the pawls being rotated so that the balls then bear on adjoining surfaces of the pawls. When the line is subsequently slackened the balls (183) act on the pawls to rotate them further into the housing so that on subsequent engagement by the collar (184), they are free to rotate so as to allow the collar to pass through the housing. This system provides an automatic latching of the line (179) followed by automatic disengagement of the latch simply by releasing tension in the line followed by reapplying such tension. Therefore latching and unlatching can be effected simply from a position remote from the latching mechanism.

Abstract: The improved pipe flushing device comprises an elongated, elastomeric, hollow tubular member having a middle portion free to expand radially under water pressure. The rear Inlet end of the tubular member is fitted with a hose connector, while the narrow front outlet end of the tubular member contains a valve which opens upon expansion of the middle portion. The valve has a cage bearing a rear plate closure, and open sides and front. The rear plate is received in a transverse groove in the outlet, which groove is of a greater length than the thickness of the plate. The cage is gripped and held in a fixed position while the tubular member is in the relaxed unexpanded state. However, when the device is inflated by water pressure from a water hose connected to the inlet connector while in a water pipe, the middle portion thereof expands to meet the wall of the pipe. When the expansion is complete, the cage moves back in the outlet, the plate moving resrwardly in the groove to cause a mechanical vibration in the tubular member and water pipe. Waterthen by-passes the plate and passes through and out of the cage as a jet to break up a sewage clog. Upon expulsion of the jet, the middle portion contracts and the valve moves forward and closes, again causing sonic vibrations in the tubular member and water pipe. The expansion and contraction of the tubular member rapidly alternate to rapidly pulse water jets and vib ate the pipe to unclog the pipe.
