Title: Arc discharge lamp with ultraviolet radiation starting source
Inventor: ZASLAVSKY GREGORY
IPC: H01J65/00
Filed: 1988-09-22
Granted: 1992-06-09
Abstract: ABSTRACT     A metal halide arc discharge lamp comprises an arc tube containing a chemical fill including mercury and metal halides and having first and second electrodes respectively  sealed  at  opposite  ends  thereof.  An outer envelope surrounds the arc tube and has first and   second   terminals   for   electrical   connection thereto.   A  source  of  ultraviolet   radiation  is provided within the outer envelope proximate the arc tube  for  producing  radiation  which  illuminates  the path  between  the  electrodes  of  the  arc  tube  to decrease the amount of time for generating a gaseous discharge therebetween.   The ultraviolet light source includes an envelope of ultraviolet light transmitting material  containing  a  fill  material  and  having  a single  electrode  sealed  in  one  end  thereof.   The single  electrode  is  electrically  coupled  to  one electrode of the arc tube.  A portion of the envelope of  the  ultraviolet  light  source  is  capacitively coupled to the other electrode of the arc tube such that the source produces ultraviolet radiation during lamp starting when the first and second terminals of the lamp are energized.

IPC: D06M13/08

Abstract: ABSTRACT OF THE DISCLOSURE         A method for producing a low cost impregnated and  coated  fiber  useful  in  forming  pump,  valve, expansion joint, hydraulic cylinder and similar packings capable of resisting high caustic concentrations  is provided.  In accordance with this method a relatively low  cost  yarn,  such  as  rayon,  is  simultaneously subjected to a spreading operation and passed through a highly alkaline  colloidal tetrafluoroethylene  (TFE) solution.  As the yarn fibers are spread from a fiber bundle to a flat ribbon-like array of spaced parallel fibers, the fibers swell or "balloon," thus allowing the TFE to completely penetrate the interior of each fiber. A subsequent coating step insures that the exterior of each fiber is completely coated with the TFE solution. Fibers produced according to the present process are characterized by substantially lower cost than available materials,  are completely caustic resistant at a pH approaching or exceeding 14, and have a long, useful service life in a variety of different environments.

Granted: 1993-03-23
Abstract: Abstract of the Disclosure A shutter mechanism having an electromagnet and a flexible ferromagnetic blade mounted in narrow V-shaped relationship to one another at an end opposite from a light source, with a light path passing between the two. The electromagnet has a cylindrical core with a length-wise slice defining poles and a toroidal wire winding about the core. When the magnet is activated, the free end of the blade flexes toward the poles completing the magnetic circuit, and either opening or closing the shutter.  In a normally open embodiment, the light path passes between the magnetic poles, and the blade, normal-ly parallel to the beam path, flexes downward to block the beam.  In a normally closed embodiment, when the blade flexes the light path passes through a slot in a backup plate against which the blade normally rests.  The normally closed embodiment includes a light absorptive tongue between the poles which combines with the reflec-tive blade to define a light trap.  In the normally open embodiment, the blade combines with a light absorptive slotless backup plate to define the light trap.

The instruction interface controls communications with  the  external  instruction  cache  and  coupled  the instructions  from the  instruction cache  to the micro-processor  at  very  high  speed.  The  data  interface controls communications with the external data cache and communicates  data  bi-directionally  at  very high  speed between  the  data  cache  and  the  microprocessor.    The execution unit selectively processes the data received via the data interface from the data cache responsive to the execution unit decoding and executing a respective one  of  the  instructions  received  via  the  instruction interface from the instruction cache.  In one embodiment, the external instruction cache is comprised of a program counter  and  addressable  memory  for  outputting  stored instructions responsive to its program counter and to an instruction cache advance signal output from the instruc-tion interface.  An address generator in the instruction interface  selectively  outputs  an  initial  instruction address  for  storage  in  the  instruction  cache  program counter resonsive to a context switch or branch,  such that  the  instruction  interface  repetitively couples  a plurality of instructions from the instruction cache to the  microprocessor  responsive  to  the  cache  advance signal,  independent  of  and  without  the  need  for  any intermediate or further address output from the instruc-tion interface to the instruction cache except upon the occurrence of another context switch or branch.

Abstract: This invention relates to a catalyst and a method for producing said catalyst. At least 60 percent by weight of the catalyst consists of copper oxide, aluminum oxide-spinel and 60-100 percent of the copper present is bound to aluminum oxide as copper oxide, aluminum oxide-spinel, where the molar ratio Cu:Al=0.25-0.50. The catalyst itself contains 1-20 percent by weight of zinc oxide which is present in the pores of the spinel. Further amounts of zinc oxide may be admixed mechanically or be present as a coating on the catalyst tablets. The catalyst is especially well suited for conversion of carbon monoxide with steam to hydrogen. The catalyst is produced by precipitation of copper- and aluminum salts at pH=6.0-6.5 during addition of an ammonium carbonate solution. After filtration and drying, the product is calcined at 750 DEG -850 DEG  C. until there is obtained a product having a 60-100 percent spinel structure. Zinc salt is introduced in the pores of the spinel, and the product thereby formed is heated up to at least the decomposition temperature for the zinc salt which is then converted to zinc oxide. Possible addition of zinc oxide in addition to that introduced into the pores of the spinel may be admixed mechanically.
