Title: Apparatus for improving the signal to noise ratio in wireless communication systems through message pooling and method of using the same
Inventor: JAVITT JOEL I
IPC: G06Q30/06
Filed: 1995-12-01
Granted: 2003-01-07
Abstract: Apparatus for improving the signal to noise ratio in wireless  communication  systems  through  message  pooling including hardware, software and protocol contained within a packet data communication system which enables a wireless communication  system,  for  example  an  electronic  display system,  to adapt communication techniques to meet customer based accuracy requirements independent of changes in the signal  to  noise  ratio  of  the  communication  channel  and methods of using the same.  Communication having low signal to   noise  ratios   are   improved   using   intelligent retransmissions of the communication signals and statistical detection or demodulation.  Such techniques are particularly useful when used in wireless communication in unbalanced systems, such as electronic display systems.

Granted: 2002-10-01
Abstract: A     process for the selective hydrogenation of the diolefins and acetylenic compounds in an olefin-rich aliphatic hydrocarbon stream (1) comprises contacting the feed stream (1) at 40-300 °F under low hydrogen partial pressure of 0.1-70 psia at a total pressure of 0-350 psig in a distillation column reactor (10) containing a hydrogenation catalyst bed (12) which serves as a component of a distillation structure (10), such are supported PdO encased in a tubular wire mesh. Essentially no hydrogenation of the olefins occur. The feed stream (1) enters below or at the lower end of the catalyst bed (12), and is contacted with hydrogen fed through line (2) in the catalyst bed (12). The overhead (3) is obtained at the overhead, condensed in a condenser (20) and separated in a settler (30), and partially recycled back to catalyst bed (12) as a reflux stream (6). The bottom stream (11) is obtained at the lower end of the distillation reactor, and is partially recycled back as stream (4) after being heated in a heat exchanger (40) as recycle stream (13).

Title: Heat pipe heat exchanger tube sheet
Inventor: GIAMMARUTI ROBERT JOSEPH
IPC: F28D15/02
Filed: 1996-06-17
Granted: 2000-03-07
Abstract: A method and apparatus for separately supporting and sealing a heat pipe within a heat exchanger.  For support, the heat pipe with fins thereon passes through a support grid which consists of a series of rings secured or interconnected together.  The fins of the heat pipe rest upon these rings of the support grid thereby supporting this region of the heat pipe.  To seal these heat pipes in order to prevent any gas escape from the heat exchanger, a tubesheet with openings therein is placed over the ends of the heat pipe.   These openings are oversized thus a considerable gap exists between the tubesheet and the heat pipe.          This gap is covered or sealed by use of a cover disk which tightly fits around the heat pipe and spans across this gap before it is removably secured to the tubesheet.   By this fashion, once the cover disk is removed from the tubesheet, it is a relatively easy task to then remove the tubesheet and the heat pipe from the heat exchanger for maintenance or repair purposes.

Abstract: A flexible, gussetted package having an interior for holding some particulate material product, under vacuum, and which includes a mouth to be opened to provide access to the contents of the package. The package is formed of a flexible material and includes a front panel, a rear panel, and a pair of opposed side gussets and a pressure equalizing valve. The valve is arranged to operate in a first mode of operation wherein any gasses within the package are allowed to vent to the exterior of the package, while the ambient atmosphere is precluded from entering into the interior of the package. The valve also operates in a second, transitory, mode wherein it allows a small amount of the ambient atmosphere to gain ingress into the interior so that the package's walls give a smooth appearance. The valve then enters into its third mode of operation wherein it isolates the interior of the package from the exterior.

Abstract: A coaxial dielectric filter comprising a straight cutoff waveguide, at least two coaxial dielectric resonators disposed coaxially or substantially coaxially and at an interval in the cutoff waveguide in its lengthwise direction, a rod-like input-side antenna whose leading end stands close, or inserted, to the inside of an input-side inner conductor of the coaxial dielectric resonator disposed on the input side, and a rod-like output-side antenna whose leading end stands close, or inserted, to the inside of an output-side inner conductor of the coaxial dielectric resonator disposed on the output side. This filter is characterized in that an adjacent-side end of at least one of coaxial dielectric resonators adjacent to each other forms a slope which is inclined with respect to the cutoff waveguide in its cross section perpendicular to the lengthwise direction.     In the adjustment of distance between the coaxial dielectric resonators adjacent to each other, the distance between the coaxial dielectric resonators on their adjacent sides can be adjusted simply not only when the coaxial dielectric resonator provided with the slope is moved in the lengthwise direction of the cutoff waveguide but also when it is moved in the width direction of the cutoff waveguide.
