A butterfly valve disc with generally oval plane surface, tiltingly arranged so that the outer periphery forms a perfect circle intersecting with the inner bore of a butterfly valve, and where the outer rim of the disc further supports a row of ribs arranged generally parallel to the circular bore of said butterfly valve and pointing in opposite directions below and above the disc's horizontal axis and forming between themselves a number of flow passages, the trapezoidal cross-section of which g...
Extremely low bounce switching characteristics are achieved by biasing electrical switch conductors with a torsion beam member. The torsion beam member includes a torsion beam portion having an axis which is restrained from rotation thereabout at a first point and an operating beam portion connected to the torsion beam portion at a second point spaced from the first point. The axis of the operating beam is oriented at an angle with respect to the axis of the torsion beam such that displacement o...
A process for manufacturing low oxygen and low sulphur steel in plasma arc furnace with or without induction heating under the condition of inert gas and special flux.
A hydrocarbon feedstock comprising naphthenes is catalytically reformed using a catalyst which promotes both dehydrogenation and isomerization. Cracking and other undesirable side reactions are substantially avoided by employing a reaction temperature in the range of 600.degree. to 700.degree.F and a hydrogen pressure not exceeding about 4 atmospheres. If the hydrogen partial pressure is about 1 atmosphere or less, satisfactory conversion of the naphthenes to aromatics is obtained without furthe...
An IC oscillator is disclosed using a small capacitor to determine the fundamental frequency. The capacitor is small enough to permit an on chip capacitor to be used. The capacitor is charged and discharged at the same rate between voltage limits established in the circuit. A single voltage controlled current source controls the charge and discharge currents equally so as to provide a relative low voltage-controlled frequency. The circuit can operate at very low charging currents so that a wide ...
The invention involves a steel and the process of making it, which steel is especially adapted for welding at good productivity to produce a product well able to meet the special low temperature requirements for such purposes as ships for transporting liquified natural gas, without departing from normal steelmaking and rolling practices beyond ordinary normalizing. The steel for this and other reasonably similar purposes will have the following composition range:
A low-voltage fuse, and in particular a low-voltage fuse of the polyphase variety, has a specific array of fusible current-carrying means arranged between juxtaposed surfaces of a pair of spaced terminal bars. These surfaces are provided with grooves extending in a direction longitudinally of said pair of terminal bars. The aforementioned array of current-carrying means is formed by a plurality of stampings of silver or copper, each including a pair of spaced terminal strips and each further inc...
Multiplexed analog signals are applied to the input of a sampling amplifier having a digitally controlled gain. The signals at the output of the sampling amplifier are applied to an analog to digital integrating converter. A phase lock oscillator is connected to a clock which controls the operation of the converter in such a manner that the integration time of the converter is equal to one or more cycles of the power line frequency, whereby maximum common mode rejection occurs at the power line ...
