Abstract: Crack-free hydrides of zirconium and zirconium-uranium alloys are produced by alloying the zirconium or zirconium-uranium alloy with beryllium, or nickel, or beryllium and scandium, or nickel and scandium, or beryllium and nickel, or beryllium, nickel and scandium and thereafter hydriding.

Abstract: A magnetic information card encoding apparatus wherein the train of clock pulses used to synchronize the release of binary data from a storage register to a recorder head is generated by the motion of the card itself. Structural means forms a card receiving slot into which the card is manually inserted and removed. A rotatable carriage assembly consists of a drive shaft, photoelectric means responsive to rotation of the drive shaft for generating the clock pulse train, an idler wheel, and spring biasing means for urging the idler wheel against the drive shaft in a friction drive relationship. A second spring biasing means urges the carriage assembly to rotate such that the idler wheel frictionally engages the card so as to be driven thereby. A switch is actuated by the leading edge of the card to provide a signal defining the position of the card in the slot. The arrangement is such that the information card is erased on insertion and encoded on withdrawal.

Abstract: An in-line safety reflector assembly for attachment to a spoked wheel of a cycle for improved end visibility of the cycle. Two planar reflectors are attached to opposite sides of a spring metal base plate, the inner end of which has a curved portion forming a spring clip for attachment to the wheel hub and the outer end of which has a laterally protruding spoke clamp which can be crimped onto a spoke. The reflectors lie in a plane parallel to the hub axis, lie wholly within the protected space generated by the revolving spokes, and have an extensive surface area, extending substantially the entire width of such space and the major portion of the length thereof.

Abstract: A seismonastic control apparatus has a ball mounted in a concavity for unobstructed movement into contact with a displaceable disc which actuates a two-mode control device on predetermined tilting or shock loading of the apparatus.To increase the kinetic energy of the ball and thus facilitate displacement of the disc, the seat is formed with a circular region at which the inclination of the seat to the central axis of the apparatus increases. As the ball crosses this region it is accelerated more rapidly because its path becomes more closely aligned with the resultant force acting on the ball.

Abstract: A flexible resilient magnetic particle type information card capable of correctly reading information thereon after such card has been bent double on itself and creased, said card comprising a flexible base, a layer of uniformly distributed magnetic particles thereon, and a flexible overlayer of nonmagnetic material, said over layer having a thickness of at least 2 mils, said layer of magnetic particles being magnetically encoded, the magnetic flux transitions of such encoding being at least 0.02 inch apart and said magnetic particle layer being enclosed between the base layer and over layer and spaced from the edges of the card.A method of storing information in binary data form comprising magnetically recording information on a magnetic strip that has an over layer of at least 2 mils by inducing transitions in the magnetization of the strip at a minimum spacing of 0.02 - 0.1 inch.
