Abstract: A latching system for securing the header of a convertible top frame to the windshield frame top piece including a pair of laterally spaced latching mechanisms operated by a central rotary handle, each mechanism having a striker bar reciprocated between a locking and release position by a crank actuated pull bar actuating the striker bar. The striker bar is received into a recess formed in a striker block fixed to the windshield frame top piece when the striker blade is moved to the locking position and these elements coact to draw the header down to be securely latched. As the striker bars are advanced, downwardly inclined guide tangs are inserted in an inclined pocket in the striker block. As the top frame is positioned atop the windshield frame, the tangs draw the header forward into proper forward alignment with the windshield frame top piece.

Abstract: A visor control comprises a U-shaped spring clamp with inwardly converging sides terminating in inwardly projecting rounded tips which circumscribe a portion of the visor rod in all positions of adjustment. The sides of the clamp include alternately staggered slots which cooperate with alternately staggered lobes and flats disposed along the longitudinal axis of the visor pivot rod for selectively camming the visor into a snap-up raised stored position and spreading the sides to frictionally hold the visor rod therebetween when the visor is lowered to a use position. A tang extends from a portion of at least one of the sides of the U-shaped clamp and extends into a recess in the body of the visor to hold the clamp against rotation.

Abstract: A method and apparatus for separating at least one superconductive phase from a multiphase material which may contain multiple superconductive phases and a normal phase by the use of diamagnetic force. A material containing multiple phases is pulverized into granules approximately the grain size of a selected superconductive phase and is then subjected to a force to cause movement of the particles in a particular direction. The selected superconductive phase is made superconducting by cooling the material below its transition temperature. Diamagnetic force is then generated by an applied magnetic field which deflects and separates the superconducting granules but has substantially no effect on the nonsuperconducting granules. Conversely, the selected superconductive phase has a magnetic field applied to it and then is made superconducting to cause a separation.

Abstract: A tie plate rail fastening system for securing rails to wood cross-ties is described comprising a wear plate positioned on the upper surface of each of the cross-ties adjacent the ends thereof.

Abstract: The present invention relates to a wheel cover in use for motor vehicles. The wheel cover includes a circular main body, a plurality of holding claws extending from a rear surface of the main body, and a resilient ring to be mounted on the holding claws so as to urge radially outwardly the holding claws. On the rear surface of the main body at positions between the neighboring holding claws are arranged support members each having a groove for receiving the resilient ring. The groove is defined by a bottom surface and a pair of protrusions aligning along the radial direction of the main body. The radial movement of the ring mounted on the holding claws can be regulated by the pair of protrusions so that the expansion of the ring is restricted, resulting in that the holding claws is prevented from expanding radially outwardly, and the ring is prevented from disengaging from the holding claws.
