Abstract: ABSTRACT            The invention relates to a process for producing steel of low phosphorus content from hot metal of usual phosphorus content, in which the hot metal is simultaneously decarburised and dephosphorised in a single process step in a metallurgical vessel, in particular in a converter.          The refining gas consisting predominantly or completely of technically pure oxygen is top-blown onto the melt and an inert stirring gas is blown into the melt, particularly from below.  The vessel is charged with hot metal containing manganese in an amount of less than 0.2 % by weight.  Lime is then added and refining is carried out down to a final phosphorus content of 0.005 % by weight or less in the steel at the end of blowing, without a change of slag.

Abstract: ABSTRACT OF THE DISCLOSURE         A method in the control of a paper web reel-up particu-larly in a so-called Pope-type reel-up, which reel-up comprises a reeling cylinder, by means of which power required for reeling is introduced to a reel being formed onto a reeling drum mainly by the nip between the periphery of said reeling cylinder and periphery of the reel being formed.  The reeling procedure is begun in so-called primary forks or similar, from which the reel-ing cylinder and the bottom section of the reel formed on it is removed to secondary forks, on which the final steps of the reel-ing procedure are carried out.  The loading of said nip is at least chiefly created by power equipment influencing said primary and secondary forks.  The force of the power equipment of said forks supporting the reeling drum during the reeling procedure, which force loads said nip is adjusted by means of control sig-nals based on the position of said forks in such a way that an essentially even load distribution will come true even in the exchange step, in which the reeling drum and the reel being formed onto it is moved from the support of said primary forks to be supported by and in order to load the secondary forks.

Abstract: ABSTRACT OF THE DISCLOSURE     The reinforced optical fiber is disclosed which has a feature in its structure that a reinforcing inner layer is interposed between the buffer layer of silicon rubber and the FRP layer made of styrene resin and fibers.  The reinforcing inner layer is formed by binding filaments attached longitudinally onto the buffer layer with a non-styrene resin.  Not only does the additional reinforcing inner layer improves the crushing resistance, but also it keeps low the increase of transmission loss.    The feature of the method resides in that the reinforcing inner layer directly covering the buffer layer is formed by the steps of longitudinally attaching dry filaments to the buffer layer and then impregnating the filaments with a curable resin.

Abstract: Abstract An input filter for coupling television signals from a signal source such as an antenna to an RF signal processing stage includes series resonant input and output sections shunting the signal path.  The input section forms a trap at the video IF frequency.  The output section resonates at a frequency other than the sound IF frequency, below the band of television signal frequencies to be processed by the RF signal processing stage.  The filter serves to attenuate unwanted stray signals such as video and sound IF components otherwise capable of interfering with and distorting the input television signals.

Abstract: A process is disclosed for accurately maintaining a low alumina content of between 1 and 4.5% in a cell for the production of aluminum by electrolysis in the Hall-Heroult process. According to the invention, a control parameter P=-1/D(dR1/dt), is determined, wherein D is the variation in the alumina content of the electrolytic bath in % weight per hour, R1 is the internal resistance of the cell, and t is the time. A series of operations is then carried out in a repeated cycle, starting with the cell being fed alumina at a nominal rate which is substantially equal to the quantity consumed by electrolysis. At periodic intervals, an over-supply of alumina is added in order to enrich the bath, and the over-supply is continued for a preset time during which dR1dt is negative. The feed rate is then reduced to less than the nominal feed rate, during which time dR1dt passes through zero to become positive and the regulation parameter P, the value of which tends to rise, is measured often. The successive values of P are compared with a required preset value Po. As soon as P equals Po, the feed rate is returned to the nominal feed rate and a new cycle is recommenced.

Abstract: PLANETARY GEAR SET AND ASSEMBLY METHOD Abstract of the Disclosure A planet gear set and method of assembling the carrier on the sun and ring gear particularly suited for automation of the carrier assembly operation.  The sun gear of the planetary set has a staging annulus formed on one end thereof defined between the addendum and dedendum circles of the sun gear teeth.  The sun gear also has a frustoconical concentricity chamfer formed on the same end with one edge contiguous with dedendum circle edge of the staging annulus.  The carrier, with the planet gears thereon, is aligned on the axis of rotation of the sun gear and advanced toward the same.  If the sun gear is eccentric relative to its axis of rotation, the planet gears engage the concentricity chamfer and cam the sun gear to an aligned position which is achieved when the carrier achieves a staged position relative to the sun gear. In the staged position, the addendum circles of the planet gears are tangent to the dedendum circle edge of the staging annulus.  The carrier is then mildly biased toward the sun gear and rotated, whereupon the teeth of the planet gears sequentially achieve meshing engagement with the sun gear teeth.

Abstract: ABSTRACT        An expansion joint is shown for use in a roadway having concrete sections and a slot therebetween. The joint includes a preformed longitudinal sealing element which is formed of a resilient material and installed within the slot. An initially flowable adhesive material is applied between the sealing element and opposing side surfaces of the concrete sections making up the joint. The moduli of elasticity of the adhesive material and sealing element are selected so that forces exerted upon the joint by expansion and contraction of the concrete sections result in movement of the central sealing element, rather than exerting strain upon the adhesive bond.
