Abstract: A new and distinct variety of Syzygium paniculatum, which is a periclinal chimera arising from the stump of a normal Syzygium paniculatum is presented. This new variety possesses attractively variegated leaves. Specifically, the mature leaves are a combination of medium and deep greens and have creamy white margins. The overall appearance of the mature plant is pearly when viewed from a distance. The new variety retains the upright form and drought tolerance of the parent. The leaves, prior to dropping change color and show blushes of orange and gold. Flowers are rare and fruit even rarer, usually developing without any seed.

Abstract: A non-expansible linkage bracelet and method of manufacture thereof, wherein the bracelet includes: a set of laterally adjacent top links having channel-shaped sections with .Iadd.width dimensions defined by .Iaddend.parallel side members .Iadd.which are .Iaddend.joined by top members, .[.one side member.]. .Iadd.the channel-shaped sections .Iaddend.of each top link .Iadd.being separated by an intermediate decorative section, and each top link .Iaddend.having at least one bendable locking lug protruding .[.therefrom.]. .Iadd.exclusively from one side thereof, each of said decorative sections having at least one recess on the said one side located laterally within said width dimensions, and at least one projection on the side opposite to said one side extending laterally beyond said width dimension .Iaddend.

Abstract: Concrete having high resistance to corrosion is prepared by using low aluminate (C.sub.3 A) cement, preferably having less than 5 weight percent of aluminate, and, in addition to conventional concrete constituents, at least 10 weight percent of finely divided, reactive silica based on the cement weight.A highly corrosion resistant cement composition comprises, in addition to conventional cement constituents, 70-90 parts by weight of low aluminate cement and 10-30 parts by weight of reactive silica.An additive useful for making concrete highly corrosion resistant comprises 80-90 weight percent of reactive silica, 0-10 weight percent of low aluminate cement, 3-8 weight percent of formaldehyde condensed sodium sulfonate, 3-8 weight percent of lignosulfonate.

Abstract: The fluidic oscillator consists of a resonant fluid circuit having a fluid inertance and a dynamic fluid compliance. The inertance is a conduit interconnecting two locations of a chamber on each side of a working fluid jet issuing into one end of the chamber, the inertance conduit serving to transfer working fluid between the two locations. Through one or more output orifices located approximately at the opposite end of the chamber, the fluid exits from a chamber exit region which is shaped to facilitate formation of a vortex (the dynamic compliance) from the entering fluid. The flow pattern in the chamber and particularly the vortex in the chamber exit region provide flow aspiration on one side and surplus of flow on the opposite side of the chamber, which effects accelerate and respectively decelerate the fluid in the inertance conduit such as to cause reversal of the vortex after a time delay given by the inertance.

Abstract: A chart recording instrument having electromechanical servos which move a pen or stylus in the X-direction along a paper chart, and move the chart with respect to the pen in the Y-direction. A novel mechanism provides for ease in loading and unloading charts, and for accurate relocation of the chart, whereby a chart can be removed from the machine and then replaced accurately without disturbing any of the gain or zero control settings. Thus a curve can be recorded, the chart removed, and then put back to record another curve in the same family. These functions are controlled by a three-position lever which lifts and lowers the pen, raises and lowers pinch rollers in the Y-axis chart drive system, controls a pair of chart positioning stops, and switches appropriate positioning voltages to the servos.
