Abstract: ABSTRACT OF THE DISCLOSURE        The invention provides a spring suspension system for vehicles, particularly for passenger-carrying rail vehicles, one of its principal advantages being its ease of retrofit to upgrade existing systems employing vertical coil springs.  The vertically-movable journal boxes are provided with vertical metal friction surfaces cooperating with longitudinally and laterally spring urged low friction surfaces mounted on the vehicle frame.  Small displacements of the boxes are accommodated by "internal friction" in the longitudinal springs without appreciable relative movement between the friction surfaces, but larger displacements cause such movement with consequent application of sliding friction damping forces.  The preferred form of the longitudinal springs is elastomer springs of chevron cross-section disposed with the chevron cross-section horizontal, so that they provide both the lateral and the longitudinal springing.  The system is also applicable to other systems, such as the secondary suspension between the frame and a body-supporting bolster thereon.

Abstract: ABSTRACT MULTISTAGE PROCESS FOR PREPARING FERROBORON A process for preparing ferroboron comprises first heating a mixture of boron oxide or boric acid, iron or iron oxide, carbon, and a carbohydrate to produce a foraminous char.  During a subsequent two-stage reduc-tion process in an electric or arc plasma furnace, ferroboron is produced and gaseous boric oxides are evolved.  The boron values are captured as they move to the cooler regions of the furnace, resulting in high boron yields.  The process is particularly useful in preparing pure and inexpensive raw material for the production of amorphous ferroalloys.

Abstract: METHOD AND APPARATUS FOR ASSEMBLING SLIDERS ON AN UNCUT FASTENER CHAIN Abstract A method and apparatus for feeding sliders to a slider pocket are disclosed.  Sliders taken from the pocket are assembled on the fastening element sections of an uncut fastener chain which is moved and stopped intermittently to allow the assembly of the sliders, wherein sliders longitu-dinally aligned and delivered by a slider chute are fed into a slider holder one at a time.  The slider holder carrying a slider received from the chute is transferred to a slider assembling station from a direction at right angles to the direction of fastener chain transfer, and the slider is loaded at the slider assembling station into the slider pocket which is provided at the upper end of a slider pocket block raised from the direction at right angles to both the fastener chain transfer direction and slider transfer direc-tion, and the slider holder is returned to the exit of the slider chute.  These steps are repeated in synchronism with the stopping of movement of the uncut fastener chain.  In loading the sliders into the slider pocket, the sliders are introduced from the side of the pocket so that the slider pull tab will not pose an obstacle, regardness of its shape.

Abstract: -ABSTRACT OF THE DISCLOSURE    A METHOD FOR THE PREPARATION OF PHENYL PYRUVIC ACID    The invention provides an improvement in the method for the preparation of phenyl pyruvic acid by the reaction of benzyl chloride and carbon monoxide in a liquid reaction medium in the presence of a cobalt carbonyl as the catalyst. In the inventive method, the reaction is performed in the presence of calcium hydroxide and the reaction medium is a binary system composed of water and an organic solvent capable of dissolving the catalyst and not freely miscible with water.  The reaction can proceed even under normal pressure and the desired product can be readily recovered in the form of precipitates of the calcium salt while the catalyst dissolved in the organic phase after completion of the reaction can be recycled and re-used as such in the next run so that the costs for the catalyst regeneration in the prior art can be entirely saved.

Abstract: ABSTRACT     A new punch anvil is provided for use with an axial punch for use in a fastening system of the kind in which the punch displaces a portion of one sheet member, such as a thin metal sheet, into another sheet to fasten them together, the punch and die cooperating to form a "button" of sideways displaced material that locks the sheets together.  The anvil consists of two parts, one of which is of smaller transverse dimension than the other to form a transverse shoulder between them.  The anvil end against which the members are clamped to be punched is surrounded by a jaw which is split longitudinally to be in at least two members held assembled by an encircling resilient ring or collar, so that the jaw members can move apart transversely and/or their upper ends in contact with the clamped members can rock apart on the shoulder to release them upon conclusion of the fastening operation.  The jaw members are retained on the anvil as the punch withdraws by an annular ridge cooperating with an annular groove or by two radial pins.  The longitudinal position of the anvil member may be adjusted to correspond with the punch stroke by means of a screw-threaded member in a correspondingly internally screw-threaded counter-bore.
