Title: Uranium high-density dispersion fuel with spherical uranium alloy power solidified rapidly by atomization method, and the fuel fabrication process
Inventor: KIM CHANG-KYU
IPC: G21C3/60
Filed: 1999-09-14
Abstract: This invention comprises of high-density fuels dispersed with atomized spherical particles and the fuel fabrication processes.      Comparing with the conventional method, this has many advantages for the direct formation of meta-stable .gamma. -U phase, the process simplification, the minimization of fabrication space, the improvements of production yield, fuel productivity, powder purity  and fuel formability, a higher thermal conductivity in real heat flow direction, the decrease of as-fabricated porosity, and a smaller thermal swelling.        Uranium and alloying metals are charged in a heat-resistant crucible having a stopper and a small orifice. The atomizer chamber is evacuated up to the vacuum degree of above 10 -3 torr using vacuum pumps. Uranium and alloying metals charged in the crucible are melted by vacuum induction or arc heating. The alloy melt is fed through a nozzle onto a rotating disk. Then melt droplets are formed and spread by the centrifugal force of rotating disk. The flying fine droplets are cooled rapidly (above 10 4 °C /sec in cooling rate) under an inert atmosphere of argon or helium gas due to the large specific surface area.

Abstract: Striped patterning of dyed fabric (10), particularly dyed denim, is obtained by impacting the fabric with a row of columnar jet streams (27) of fluid generated by a manifold (26) under pressure while conveying it on a support member (22) in a machine direction through a patterning station (14). The orifice gauge and diameter, manifold pressure, and line speed are selected to obtain optimal striping without blurring, loss of fabric strength, or durability, or excessive warp shrinkage. Preferably, the jet strip is removably interchangeable in a common hydrojet manifold for forming different kinds of striped patterns. The back side of the denim fabric may be subjected to pretreatment to cause the surface of the dyed warp side to fill in and darken with color. A strié striping effect can also be obtained using a combination of jet strips. The striped patterning station (14) can be incorporated at any suitable point in a conventional denim finishing range.

Title: Equine dental grinding apparatus
Inventor: HERRON W BRUCE G
IPC: A61D5/00
Filed: 2000-09-06
Abstract: A dental appliance or apparatus for grinding the teeth of equine patients includes a variable speed motor and an elongated tube leading from the motor to a head member that mounts an annular disk-shaped grinding wheel that has a planar grinding surface thereon. The head member also mounts a cup-shaped guard member that has a skirt portion extending beyond the grinding surface of the grinding wheel so as to protect the tongue and mucosa of the patient during the grinding operation. The elongated tube permits the grinding wheel to be inserted into the horse's mouth to bring it into close proximity to teeth needing to be ground and the grinding wheel can be easily oriented relative to the teeth to be ground since it can be rotated through several angles relative to the motor to reach both upper and lower sets of teeth. A drive shaft couples the grinding wheel to the motor, is contained within the elongated tube, and is connected to the motor through a clutch assembly. Should the horse bite down on the grinding wheel and stop its rotation the clutch will prevent the motor from stalling or from twisting in the operator's hand. A water cooling accessory can be provided to spray cooling water directly at the grinding surface. By using this apparatus a more effective grinding operation can be performed and there is less danger of damage to the inner walls of the horse's mouth or to its tongue than with conventional grinding or filing techniques.
