Abstract: : Procédé de fabrication d'un élément de microfiltration, d'ultrafiltration ou d'osmose inverse. La présente invention concerne un procédé de fabrication d'un élément de microfiltration, d'ultrafiltration ou d'osmose inverse, dans lequel on hydrolyse un alcoxyde, un composé organo-métallique ou un sel métallique d'un acide minéral ou organique dans un solvant organique anhydre, de façon à obtenir un sol de particules d'oxyde ou d'hydroxyde, on ajoute à ce sol un agent épaississant, l'on dépose par engobage une couche mince du mélange sur une couche-support de pores plus gros que ceux désirés pour l'élément, ou l'on sèche la couche déposée en atmosphère suffisamment humide pour permettre l'hydrolyse de l'alcoxyde, du composé organo-métallique ou du sel métallique, puis l'on effectue un traitement thermique de la couche déposée entraînant l'élimination de l'agent épaississant, puis le frittage des particules de cette couche, caractérisé en ce que l'on ajoute au sol, en plus de l'agent épaississant, un acide fort dont l'anion ne complexe pas les ions du métal de l'oxyde ou de l'hydroxyde, et en ce que l'on effectue le'ngobage par simple mise en contact, sans filtration.

Abstract: COMBINED SHEET FED ROTARY PRINTING MACHINE FOR     SECURITIES, IN PARTICULAR BANK-NOTES                  ABSTRACT OF THE DISCLOSURE            The  printing  machine  has a multi-colour offset printing unit;  behind  this  a  sheet  conveying  device,  and  an intaglio  printing  unit  to  which the sheets printed and provided with register marks in the  first  printing  unit are transferred  by  the  conveying device. The conveying device comprises a detector  system  responding  to  these register  marks,  and  a  register  drum.  Each of the two printing units and the register drum have their own  drive mechanisms  mechanically  independent  of  each other. The drive mechanism for the second printing unit is controlled in  dependence  upon the speed of the first printing unit, and the drive mechanism for the register drum is  control-led  on  the  one hand in dependence upon the speed of the second printing unit and on the other hand  in  dependence upon  the  register deviation measured in the circumferen-tial direction. Further, on the register drum are disposed devices  for  correcting  side  register and any skew of a sheet in dependence upon the measured register deviations.          A  second detector system reads the position of the above-mentioned register  marks  relative  to  further  register marks applied in the intaglio printing unit, and if neces-sary performs fine correction of register.

Abstract: ABSTRACT      An improved apparatus for plating interior surfaces of electrical terminals that are spaced apart and attached to a carrier strip is disclosed. The apparatus is comprised of strip feeding means which feeds the strip of terminals to a rotating mandrel which guides the terminals through a plating zone while they are plated, a source of electrolytic plating solution, and a source of electrical potential for applying electrical current flow from an anode through the solution to a cathode. The mandrel has a plurality of anode extensions located about its axis of rotation, said anode extensions being movable into and out of the interiors of the terminals that are against the mandrel. The mandrel further has a plurality of nozzles located about its axis of rotation, said nozzle being associated with but separate from said anode extensions. A conduit supplies electrolyte solution under pressure through the nozzles and into the terminals in which the associated anode extensions have been received, the anode extensions being constructed for withdrawal from the terminals prior to those terminals exiting from the mandrel.

Abstract: ABSTRACT     Hermetically sealed fiber optic cables (LW) are conducted through an insulator column consisting of several hollow insulators.  The fiber optic cables (LW) are fastened to a support element (TE), whose one end is connected to the reference potential and whose other end is connected to a high voltage. The support element (TR) is characterized by a surface having only limited electrical conductivity.  This assures that, as a result of the even field strength distribution thus guaranteed, no impermissibly high voltages are impressed on the fiber optic cable (LW).

Prefabricated  weeping tile of  the present  invention consists of  PVC perforated  standard drainage  pipe  covered  with  a  pre-formed  split  shell formed from a beaded material with a binder for bonding purposes which is permeable to water and which in turn is covered with a filter blanket fabric sleeve.  The lengths of pipe are easily connected together due to the bell and socket type fittings on each end of the pipe sections and they also resist displacement when backfilling.

Abstract: ABSTRACT OF THE DISCLOSURE          A washing  machine  uses  a  turbidimeter  to  measure turbidity  of  cleaning  water  for  controlling  the duration of its washing and cleaning cycles.  Quality of this control  is improved by taking measurements when the water flow is weak so that the effects of foams are negligible and waiting until turbidity drops at the beginning of the cycle to detect the initial value used in subsequent steps.   Sensitivity of the turbidimeter is automatically adjusted  for accuracy when  the  operation  is  temporarily  stopped  and restarted during a cycle.

Abstract: ABSTRACT          A multi-axis industrial robot is disclosed which is built according to a modular concept that can be varied very widely from the point of view of the gearing system used therein.  The robot comprises a frame, a cross-arm mounted on the frame so as to be able to pivot, and a boom mounted on said cross-arm so as to be able to pivot.  The modular construction has been effected in that the cross-arm and the pivot drive system for the boom, and the pivot drive system for the cross-arm itself are accommodated with-in the cross-arm.  It is preferred that the complete drive systems be housed in the cross-arm, with only the driven members being on the outside.  The driven members are centered and connected to the frame and the boom such that they cannot rotate.  This means that the cross-arm rotates about the stationery driven member relative to the housing.  The drive systems consist in each instance of a motor and a two-stage synchronous belt drive, the second stage of which can be configured as a spur gear system.     772-594 sch

Abstract: Abstract Disclosed is a process of fabricating a submicron wide single crystal silicon structure protruding from a monolithic silicon body.  Starting with a single crystal N silicon body having a P region, an insulator stud of sub micron width and length dictated by the limits of lithography is formed on the P region.  Using the stud as a mask, the P region is etched forming the top narrow portion having the stud width projecting from the silicon body.  On the exposed sides of the top portion oxide walls are formed and the etching continued forming the middle portion of a width exceeding that of the top portion.  An oxide-nitride wall is established on the exposed sides of the middle portion and, using the resulting structure as a mask, the etching is continued to completely etch through the P region and a substantial portion of the underlying N silicon body thereby forming a free-standing silicon protrusion structure.  Thick oxide walls are formed on the just exposed sides of the silicon.
