Abstract: BEHRINGWERKE AKTIENGESELLSCHAFT    88/B 043 - Ma 692 Dr. Ha/Sd Abstract Process for improving the accuracy and reproducibility of the data measured in immunometric tests A process is indicated for improving the accuracy and reproducibility of the data measured in immunometric tests which are carried out using microtitration plates and in which a pipetting drift is observed. Correction is made by pipetting in a test control in a multiple deter-mination at the start and at the end of a series of samples for examination, and deriving, from the change in the values measured in this multiple determination, a correction factor, varying from the start to the end, for the intermediate samples under examination.
Patent CA-2006162-A1 (CA)
IPC: G01L13/06
Filed: 1989-12-20
Abstract: A pressure sensor (10) having over-protection  for use in environments  which subject the sensor to large pressure overloads, such as may occur when such sensor is exposed to jet and  automobile engine backfires, explosive gas furnace ignitions and similar high  pressure  events.   Essentially two capacitive  sensors are  bonded together, diaphragm-to-diaphragm,  with  the  diaphragms  (111A/111B)  spaced  but juxtaposed and  forming a  closed, reference cavity chamber (114) between them, along with a central, side, wall spacer (116C).  The  capacitance  variation  with  differential pressure is  measured between the two  diaphragms and with reference to  their respective  bases (112A/112B).  Each of the diaphragms preferably is provided with a center bearing or stops (115A/115B) for accepting the load when over-pres-sured.  When in contact at the center, the stiffness of the combined pair  of diaphragms is increased several fold over that of a single  diaphragm.    Furthermore,  providing for bottoming stops  for the  combination on either side of the sensor prevents deflection to the breaking  point, because the presence  of the  opposed bottoming  stops stiffens its respective diaphragm.

Title: Encapsulated electrostatographic toner particles and a process for producing such toners
Inventor: MITCHELL NANCY G
IPC: G03G9/093
Filed: 1990-03-15
Abstract: ABSTRACT OF THE DISCLOSURE     Encapsulated electrostatographic toner particles and a process for making toner particles.  The toner particles comprise a pressure fixable core encapsulated in a pressure rupturable shell with the outer surface of the shell being hydrophobic.          Preferably, the outer surface of the shell is rendered hydrophobic by having a thermosetting resin precipitated thereon.          The process for producing electrostatographic toner particles comprises preparing a core material, encapsulating a discrete portion of the core material in a shell by interfacial poly-condensation, and then treating the outer surfaces of the shells with a thermosetting resin to render them hydrophobic.  This enables the particles to be formed as a free-flowing, dry powder without requiring costly spray drying.

Abstract: METHOD FOR REMOVAL OF MONOVALENT IONS FROM METAL SULFATE SOLUTIONS BY ELECTRODIALYSIS                  ABSTRACT          Monovalent  ions  of  chlorine,  bromine,  fluorine,  sodium, potassium and thallium, are efficiently removed from metal sulfate-containing   solutions   by   electrodialysis   using alternating  monovalent  anion  permselective  membranes  and cation exchange membranes or monovalent cation permselective membranes.  Both monovalent anions and cations are removed, or only monovalent anions are selectively removed from the metal  sulfate  solutions.     Monovalent  anions  may  be substantially completely removed in a staged process.   The method is also useful for the removal of monovalent anions from sodium and potassium sulfate solutions.   The sulfate solutions may contain at least one metal other than zinc preferably chosen from Cu, Co, Ni, Mn, Fe, Mg, Cd, Na and K, and   which   may   be   present   in   a  dominant   amount.          Electrodialysis is carried out in one or more stages under turbulent  flow conditions,  at up to 60°C,  a differential membrane pressure of less than 150 kPa, a current density of about 10 to 500 A/m2, preferably 50 to 300 A/m2, and a pH in ranges between values from about 1 to about 9, depending on the metal in the feed.  Deposition of metals on the electrodes is  minimized.    Multi-stage  electrodialysis  enables  the attainment of very low monovalent ion concentrations and the minimizing of metal losses.

Title: Variable force solenoid for a hydraulic control valve
Inventor: STUDTMANN GEORGE H
IPC: H02K41/00
Filed: 1991-05-01
Abstract: ABSTRACT OF THE INVENTION           An improved electrically actuated solenoid is used to modulate the function of a hydraulic flow control valve.  The solenoid operates a control valve to generate a predetermined output pressure as a function of the solenoid input current.  An input pressure, provided to the control valve, can thus be modulated to provide a desired maximum controlled output pressure regardless of the input pressure by bleeding excessive pressure to a low pressure return circuit.  A lower controlled output pressure is obtained by providing the solenoid with an input current creating a magnetic flux circuit within the solenoid.  The magnetic flux circuit displaces an enhanced armature and pole piece configuration which provide a selectable output force dependent on the solenoid input current, regardless of the displacement of the armature relative to the pole piece.   By increasing the air gap surface area and increasing the air gap permeability, increases in the output force obtainable from a solenoid of relatively small physical dimensions and relatively low cost is possible.  The resulting improved output force versus current characteristics make the use of the solenoid of the present invention possible in a hydraulic control system to increase the portion of pressure bled to the low pressure hydraulic return circuit and thus reduce the controlled output pressure.
