The 123 superconductor, of the formula L1Ba2Cu3O6+.delta. wherein L is preferably yttrium, is capable of entrapping sufficiently high magnetic fields and exhibits a low microwave surface resistance. The process of preparing the superconductor comprises compacting the bulk product, L1Ba2Cu3O, and then sintering the reaction product at a temperature between about 40·C to about 90·C below its melting point, i.e., for Y1Ba2Cu3O6+.delta. at a temperature of approximately 940·C. The composition is then heated in a preheated chamber maintained at approximately 1,090·C to about 1,200·C (approximately 1,100·C for Y1Ba2Cu3O6+.delta.) until it has been decomposed, and is then rapidly cooled to a temperature between about 10·C to about 30·C above its melting point, i.e. for Y1Ba2Cu3O6+.delta. a temperature of 1,030·C, and then is controlled cooled at a rate of 1·C/hr until it reaches a temperature of about 20·C to about 40·C  bellow its melting point, i.e., for Y1Ba2Cu3O6+.delta. a temperature of 980·C. The composition is steadily held at this temperature for at least eight hours, and then cooled to a temperature of approximately 400·C below its melting point (for Y1Ba2Cu3O6+.delta. approximately a temperature of 600·C). The material is then slowly cooled by another 200·C and is then annealed in oxygen.

Abstract: A  vacuum  packaging  apparatus  for  packaging  a  product between a plastic film and a backing card comprises a base having  a  stationary  heating  hood.    A  reciprocal  table  is mounted on the base beneath the hood.  Two packaging wells are mounted side by side on the table, each well being dimensioned for holding a backing board on which the product is placed for packaging. The reciprocal table moves laterally on the base so that when one packaging well is in a packaging position under the hood, the other packaging well is not and extends out from beneath  the hood.   A sealing  frame  is mounted on the base beneath the hood for holding a sheet of wrapping material and moves  vertically between  a  raised  position  and  a  lowered position.    In  the  raised  position,  the  sealing  frame  is adjacent the heating hood to heat the sheet.   In the lowered position the sealing frame is adjacent the packaging well which is in packaging position to place the heated sheet over the board.  Vacuum motors are mounted in the base beneath the hood, under the reciprocal table.  When the sealing frame is lowered to place the heated sheet over the board in packaging position, a vacuum is drawn against the backing board to seal the heated sheet over the product onto the backing board.   A method for packaging using the apparatus is also included.

Abstract: A  system  of signal lamps for an auto or truck  places  the lamps  where  they are visible to the driver of the  vehicle,  as well  as to the drivers of other vehicles. The lamps act as  run-ning  lights  and turn signal lights. The system  comprises  four omnidirectional, surface-mounted signal lamps. These are  mounted in two pairs: an amber front pair and a red rear pair. The  front pair  is  located on that surface of the vehicle   which  is  the front-most  upper  surface of the vehicle where they  are  within the view of the driver. These front lamps alert the driver to the lamp condition directly, and also warn other motorists. The  rear pair  is  side-mounted, in places where the driver can  see  each rear  lamp in one of the side-view mirrors. These locations  make the lamps highly visible to the driver, because they are  visible in  regions where the driver habitually looks, and  because  they are  angularly close to the normal view straight ahead. They  are more  visible  to other drivers. as well . both because  they  are omnidirectional and because they are located higher than ordinary lamps, and so are less likely to be hidden when vehicles are very close  to  one another. The system may be installed  as  original equipment or added onto an existing vehicle as accessories.

Title: Hydrometallurgical process for the treatment of copper-bearing ore
Inventor: ALVAREZ ALIRO T N P
IPC: C22B15/00
Filed: 1992-12-18
Abstract: A hydrometallurgical process for recovering copper from copper bearing ores or fractions, by a process of first wetting and sulfatizing the ore with controlled amounts of H2SO4 and water, followed by acid curing and repulping to sulfatize a substantial portion of the copper in the ore.  Also, the fine and coarse fractions can be classified, followed by pile leaching the coarse fraction, preferably reusing the cycled H2SO4 solution obtained during the copper recovery process.  Since the coarse fraction is classified from the fine fraction, the pile leaching process is performed at very high specific flows, which substantially reduces the leaching period as compared with that of conventional pile leaching.
