Abstract: A drive circuit for providing burst, rather than continuously alternating amounts,  of energy for use in driving a flow tube (conduit) in a Coriolis meter  and  methods  for  use  in  such  a  circuit. Specifically,    the   drive   circuit   provides   a pre-defined burst of energy to a drive coil affixed to a flow conduit at an appropriate point during a cycle of the oscillatory motion of the conduit in order  to  maintain  the  peak  amplitude  of  the oscillatory motion substantially within a prescribed range.  This burst can be applied at a pre-defined point,  illustratively the peak, in each cycle of the oscillatory  motion  with  no  energy  being  applied during that cycle other than when the pulse occurs in order  to  reduce  the  amount  of  electrical  energy applied to the drive coil.  Alternatively, to further reduce this  energy,   a burst need not be  applied during every  such cycle but rather only  at those pre-defined points,  e.g.  the peaks,  within those cycles where the velocity of the flow conduit is less than a pre-defined limit value.

Title: Durable filtration membrane having optimized molecular weight
Inventor: PEMAWANSA KERIYAWASAM P
IPC: B01D67/00
Filed: 1992-06-18
Abstract: Abstract of the Invention The  subject  of this  invention  is  a novel  polymeric composition useful in membrane technology such as microfiltration, nanofiltration,  ultrafiltration,  reverse  osmosis  and  gas separation.    The  composition  is  formed  by  taking  a  known condensation polymer such as polyether sulfone, polysulfone or a polyarylether sulfone and modifying it to change the molecular weight distribution.  The useful polymers of the invention will have an unmodified number average molecular weight of about 63,000 or less and weight fraction of molecules with a molecular weight of 50,000 or less in the range of 30 to 35%.  Utilizing fractional precipitation or other known techniques for concentrating a high molecular weight fraction of a polymer the polymers are modified to have a number average molecular weight of a least 59,000 or a weight fraction of molecules with a molecular weight of 50,000 or less of not more than 19%.  Superior resistance to cracking and other forms of membrane degradation results from using the polymer compositions  of the present invention in filtration applications.

Abstract: An interlocking carton and lid combination is disclosed for storage of ice cream, frozen yogurt and the like.  The interlocking combination includes a rectangular container provided with flaps integrally formed therewith and attached along the upper edges of the container sides.          The flaps are folded along a crease inwardly into the container and glued along a strip portion to the side walls.  A slit is provided in each of two opposed sides on the exterior thereof, the slits being formed in the side walls at a position adjacent the flaps and located below the crease and above the glue strip adhesively coupling the flap to the side wall.  This positioning of the slit with respect to the crease and glue strip causes the unglued portion of the flap to bow outwardly.  A lid having a central portion is provided with transversely extending flanges attached along the peripheral edges of the central portion and  integrally  formed therewith.   The  flanges include an outer side and an inner flap portion connected along a crease.  Two opposed flanges have slits located in the respective flap portions and the flaps are glued to the respective  outer  sides  along  a  strip  portion  located between the slit and the edge of the flange spaced from the crease.  This configuration causes the unglued portion of the flap between the crease and the slit to bow outwardly.          The lid is receivable on the container wherein the lid slits interfere with the container side slits.

IPC: A01K63/04
Filed: 1991-06-10
Abstract: An aquarium filter system having a rotatably mounted filter body (32). The filter body is structured such that when mounted with a portion of the filter body submerged in moving water, rotational movement is imparted to the filter body by the moving water. As a result of the rotational movement at least a portion of the filter body is alternately exposed to the water and the atmosphere. This fosters the growth of aerobic bacteria on the surface of the filter body. The aerobic bacteria reduces the level of toxins within the aquarium water.

Abstract: A boarding ladder assembly for mounting a boarding ladder on a support for movement between raised storage and lowered boarding positions.  The assembly includes a guide structure that has first and second guide tracks mounted in spaced diverging angular orientation relative to each other and first and second guide track followers that are mounted therein for changing the angular orientation of the boarding ladder as it is raised and lowered.  A counterweight has an actual weight greater than the weight of the ladder.  A linkage is connected between the counterweight and ladder at a lift angle that varies as the ladder is raised and lowered to cause the counterweight to exert an actual lifting force that is sufficient to overcome the ladder weight when the ladder is in a raised position and that is less than the weight of the ladder when the ladder is in its lowered boarding position to automatically maintain the ladder in either position without the need for a latching mechanism.

Abstract: CONTROL OF NOx REDUCTION IN FLUE GAS FLOWS              ABSTRACT OF THE DISCLOSURE        The  NOx  content  in  a  flow  of flue gas is reduced  by  passing  the  flue  gas  through a first treatment  zone  and  a  second  treatment  zone.   A nitrogeneous  treatment  agent is introduced into the first  treatment zone for the selective non-catalytic reduction  of  part  of  the NOx, and the flue gas is thereafter  passed  through the second treatment zone which  includes  a  catalyst  for  further  selective catalytic  reduction  of  the  NOx.    Optionally,  a second  nitrogeneous  treatment agent is added to the flue gas in the second treatment zone.  The quantity of  NOx  in the flue gas is detected intermediate the first  and  second  treatment  zones and, optionally, after  the  flue  gas  has  left the second treatment zone.    The  quantity  of  ammonia  in  the flue gas exiting  from  the  second  treatment  zone  is  also detected.   The amounts of the treatment agents added to  the  flue  gas  are  controlled responsive to the variations  and  absolute  levels determined by these measurements.
