Abstract: 54,385 ABSTRACT OF THE DISCLOSURE A hydraulic elevator system 10 having an elevator car 12 in which car velocity V and car position L are determined  by detecting  the quantity  Q of hydraulic fluid  transferred  between  a  hydraulic  cylinder  and a hydraulic fluid reservoir.  The car velocity V is directly proportional  to  Q  and  the  car  position L is directly proportional to the integral of Q.  The car velocity V, or quantity Q,  is compared  with a desired velocity pattern, or desired flow rate pattern, PG, and the  difference is a control signal  C which is used to control the quantity Q. The car position L  may  also  be  used  to  determine the distance-to-go  to  a  target  floor, which may be used to initiate slowdown and/or  to  calculate  all,  or selected portions of, the desired pattern PG.

Abstract: PROCESS FOR PREPARING A THERAPEUTIC AGENT FOR                ROTAVIRUS INFECTION          ABSTRACT OF THE DISCLOSURE:       Skimmed colostrum or colostrum whey is treated with an ultrafiltration membrane having a fractionation molecular weight of 5 - 15 x 104 so as to separate intact physiologl-cally active proteins from the bovine milk.  The yield of immunoglobulins contained in the separated proteins is about twice as high as the value achieved by the prior art and their quality is superior.  The intact physiologically active proteins obtained by this method contain all immuno-globulins that have high neutralization antibody titres against the seven serotypes of rotavirus.  Hence, rotavirus infection can be effectively prevented or treated by admin-istering these proteins to humans or animals in the form of either a pharmaceutical agent or a beverage or food that contain such proteins.

Abstract: The architecture of a communication network comprising a plurality of nodes interconnected by a transmission facility having a bandwidth divisible into channels of respective bandwidths, e.g., optical fiber, is enhanced by fully sharing the network bandwidth among the network nodes, such that each pair of nodes, on periodic basis, dynamically establishes respective direct links to each of the other network nodes, in which a direct link is formed from a group of channels obtained from the network bandwidth. The remaining bandwidth is then used to form a pool of bandwidth which is shared among the network nodes on a dynamic basis, such as, for example, establishing a communication path between a pair of nodes to route a call from one node to the other node of the pair of nodes.

Abstract: ABSTRACT OF THE DISCLOSURE     There   is  provided   a removable   insole   for insertion  into  a  shoe,  including  a  substantially impervious flexible base having an overall anatomical shape  and  an  outer  periphery.   The  base  further includes   a   plurality   of   upwardly   extending compressible  support  columns  each having  a  central axis  and  being  attached  at  its  lower  end  to  the base.   The upper  ends  of  the  compressible  support columns remain substantially free and unattached.  An anatomical  pad  having  a  top  surface  and  a  bottom surface,   and   substantially   conforming   to   the peripheral  shape  of  the  base  is  attached  by  its bottom surface to the outer periphery of the base. The pad is, thereby, effectively spaced from the base by the support columns to form a compressible chamber therebetween.  In a preferred embodiment, the support columns are free to independently compress vertically along their central  axes  and  to move  laterally  in directions  normal  to  such  vertical  compression, thereby providing a massaging or stimulation action to  the  lower  portions  of  the wearer's  foot.

Abstract: A process is disclosed for recovering silver sulfide from a spent photographic fixer solution, which contains silver.  The process is particularly suited for treating the fixer solution in a manner which enables recycling of the solution giving rise to considerable reduction in cost of fixer solution and reduced environmental pollution.  The process comprises introducing a hydrosulfide reagent into the fixer solution, which contains silver, to precipitate silver sulfide while maintaining pH and thiosulfate levels in the fixer to allow for reuse.  The precipitate is isolated from the fixer solution to remove silver thereby and hence enable recycling of the fixer solution.

Abstract: ABSTRACT      Provided is  a continual  flow cell  for  separating materials  using  electrophoresis.  The  cell  includes  a solution inlet container  in  flow communication with  a vertical  flow  through  chamber  having  a  plurality  of perforated,  vertical partitions positioned therein.  The perforations are aligned to give horizontal flow paths between  two  electrodes  located  at  either  end  of  the chamber. The perforated panels are dimensioned to produce vertical flow passages therebetween. A bias potential is applied between the electrodes which produces an electric field horizontally across the cell which acts to drive charged  species  horizontally.  Outflow  ports  located horizontally across the top of the flow through chamber provide for outflow of peripheral components which may then be collected or recycled back to the inflow of another cell. The cell may also be utilized to separate materials by  isoelectric  focusing  wherein  a  pH  gradient  is established by low molecular weight impurities associated with the material.
