Abstract: ABSTRACT OF THE DISCLOSURE            A process for recovering nickel and nickel-copper from molten smelter-type slags or other highly oxidized sources of nickel and nickel-copper containing magnetite (Fe3O4) comprises reducing the magnetite in the slag with carbonaceous materials or other solid reductants which are mixed into the slag by a fluid-cooled, metal-bladed mechanical stirrer.  As a result of stirring the reductant into the slag, the rate of magnetite reduction is highly accelerated and the nickel or nickel-copper (as well as cobalt, if present) separates into a phase as either immiscible metal, a sulfide, or a nickel-copper-iron-sulfide matte, depending upon the initial composition of the slag.           A process for the combined smelting and slag cleaning of nickel-copper concentrates is also disclosed.          In this process, slag from the converter which would otherwise be returned to the smelting stage is treated in a separate reduction stage in accordance with the above procedure to recover the metal values such as copper, nickel and cobalt therefrom.  With this process no slag is returned to the smelter.            In another embodiment of the invention, smelting and converting are combined in a single stage in which a copper-nickel concentrate is burned and melted.  The result is a copper alloy and a slag containing copper and nickel, which are recovered in accordance with the above-described procedure.

Abstract: RAILWAY LOCOMOTIVE TRUCK            Abstract of the Disclosure A two-axle motor driven railway locomotive truck having a large low positioned center plate supported on a transverse bolster mounted low between the axles and carried on the truck frame by a four element focalized elastomeric secondary suspension which also transmits driv-ing and braking forces.  Elastomeric support pads are posi-tioned low with effective compression load lines intersect-ing at rail height and forming obtuse included angles to substantially eliminate weight transfer effects and provide much higher stiffness in the longitudinal driving and vertical support directions than for lateral movements and fore-and-aft pitching motions between the frame and bolster.          These effects combine with a soft primary spring suspension of the truck frame on the axle journals to provide low weight transfer for high adhesion performance and maintain good wheel load equalization when negotiating vertical rail irregularities, while eliminating wearing load carrying surfaces between the bolster and the truck frame.

Abstract: BAG FILLING MACHINE FOR POWDERY MATERIAL        Abstract of the Disclosure A machine is disclosed to bag powdery material wherein primary and secondary preconditioning chambers are used, having a volume sufficient to give enough time for the powdery material to become de-aerated.  This de-aerated powdery material is then supplied to a bulk filling station and a dribble filling station.  Bags spouted at the bulk filling station are filled to about 90 percent of their normal capacity and are then moved laterally to the dribble filling station whereat the bags are rapidly filled to a weight close to the desired exact weight and by automatic speed changing means filled to exact weight at a slower rate.  The bags are supported at the top by grippers at both filling stations with the calibrated weight scale being actuated by weight on the grippers at the dribble filling station.  An auger at the bulk filling station forces the powdery material down into a generally closed bag to force the bag open by the incoming material to thus keep air out of the bag as much as possible.  This saves time in the filling of the bags because time need not be spent waiting for the air to escape out of the powdery material in the bag before the bag can be closed and sealed.  A vacuum probe may be inserted into the bag while being filled to help this de-aeration.

Abstract: METHOD FOR PRODUCING FOAM PLASTICS AND DEVICE FOR EFFECTING SAME The present invention relates to a method for producing foam plastics and a device for effecting same. The method resides in foaming with continuous and proportioned injection of all components successively in two stages, mixing water, resin and a foaming agent under pressure with compressed air to obtain homogenized foam with a foam coefficient of 15 to 20,with subsequent injection thereinto of a curing catalyst together with compressed air. The device for carrying out the proposed method comprises proportioners the inlets whereof are connected to tanks each being intended for a respective component, as well as curing and foaming chambers communicating through two closely adjacent coaxially arranged pipes forming an annulus, the outer pipe being provided with diametrically opposite connections for letting into the annulus the catalyst and compressed air. Said method and device provide for continuous mixing of the components and simultaneous introduction of the catalyst and compressed air into the foam, which considerably improves the homogeneity degree of the foam plastic structure.

Abstract: ABSTRACT:     The invention relates to a shaving apparatus comprising a shaving cap with hair entrance apertures, and a cutting member which is rotatable relative to the shaving cap. In known shavers of this type the caps are supported by resilient means, so that the caps are adjustable relative to the skin surface being shaved. The caps are then pressed inwards relative to the housing, whilst for an optimum shaving action it is essential that the caps project a certain distance from the housing.          By making the cap pivotable about a stop on the rim of the cap, it is attempted to eliminate this drawback.

Abstract: ABSTRACT OF THE DISCLOSURE The invention provides a branching arrangement in which digital words of a pipelined incoming information flow are branched into a number of outgoing information flow branches. The term "pipelined" means that the flow is transferred through memory means whose activation inputs are controlled by clock pulses, and which are arranged successively with reference to the flow direction being coincidently activated to receive successive words of the flow.  A digital branching information flow for ordering into which of the outgoing branches the incoming words have to be branched is generated in step with the incoming flow. The basis of each outgoing branch is obtained from the output of a branching register to which the incoming flow is supplied. The branching registers are activated by the clock pulses, but if an outgoing branch contains only a part of the incoming flow, an activation locking device is used in order to block the clock pulses in dependence of the respective branching information. The branching information flow may be transferred to the locking devices through branching information registers whose activation inputs may also be controlled by locking devices.  A branching information register is, however, not to be controlled by the locking device connected to its own output.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus for feeding nuclear fuel pellets at a uniform, predetermined rate between pellet centering and grinding apparatus and a tray used for loading pellets into a nuclear fuel rod. Pellets discharged from the grinder are conveyed by a woven wire belt to a drive wheel which develops a force available to to be applied to pellets preceding it on the belt. The pellets pass under the drive wheel which adds additional weight acting vertically on each pellet.      This total weight of pellet and drive wheel coupled with wire belt linear movement acts to push a line of about 36 pellets onto a pellet dumping mechanism. As the dumping mechanism is actuated to dump the pellets on to a loading tray, the pellets moving toward the mechanism are clamped in a stationary position and the drive wheel simultaneously is lifted from its pellet contacting position until the pellet dumping process is completed. The clamping device is then lifted from its pellet and the drive wheel simultaneously is lowered into a pellet contacting position.
