Title: Method of testing the effect of a molecule on b lymphocyte function
Inventor: TEDDER THOMAS F
IPC: G01N33/53
Filed: 1990-02-16
Abstract: Abstract A method of testing the effect of an agonist or an antagonist to B lymphocyte cell surface protein CD20 on B lymphocyte function which involves determining calcium ion flux across the B lymphocyte membrane, contacting the B lymphocyte with the agonist or antagonist, and determining the change in calcium ion flux across the membrane after exposure of the B lymphocyte to the agonist or antagonist, is described. In preferred embodiments of the method the agonist or antagonist is a ligand that binds CD20 or an antibody to CD20.         In other preferred embodiments, calcium ion flux is more preferably determined in terms of transmembrane current flow and most preferrably determined in terms of the change in cytosolic Ca2+ concentration.     0187a

Patent CA-2026768-A1 (CA)
Inventor: PADGETT RUSSELL S
IPC: G06F12/02
Filed: 1990-10-02
Abstract: A selected address within one of two segments of a memory  space of  a  second  address/data  bus,  can  be accessed  from  a  first  bus  through  one  of  two  data registers.  In addition, the location of the two segments within the memory space of the second bus is selectable through two segment registers,  which are accessed from the first bus through the first data register.  A two byte wide "mode" register, which can be directly accessed from the  first bus,  stores data within three  ranges. When the mode register data is within the first range, a selected segment register can be accessed through the first data register.   A first value within this range selects the first segment register, while a second value selects the second segment register.   Data loaded into the first and second segment registers points to first and  second  segments  of  the  second  memory  space, respectively.  When the mode register data is within the second range, this data functions as a pointer to select an  address  within  a  selected  segment.   The  selected address is accessed through the data registers; the first data register accessing the selected address in the first segment,  while  the  second data  register  accesses  the selected address in the second segment.  After a selected address  has  been  accessed,  an  auto-increment  circuit increments the mode register so that the next sequential address in the selected segment can be accessed without having  to  reload  the  mode  register.   When  the  mode register data is within the first range,  the two data registers can be directly accessed from the first bus.

Abstract: Disclosed are barley flour fractions having concentrated levels of soluble dietary fiber ("SDF"). The barley flour fractions have SDF contents ranging from about 18% to 30%. Also disclosed are dry milling concentration methods for making the high soluble dietary fiber content barley flour fractions. The milling methods involve size reducing a barley flour, especially a 70% to 80% extraction flour, having a native SDF level to a controlled particle size distribution to form a size reduced flour. this is accomplished by a single pass pinmilling step followed by particle size classification at an opening of 30-60 microns to separate the size reduced flour into,a starchy fraction and the present barley flour fraction having a 1.2×-5× concentration of SDF compared to the native SDF level.

Inventor: NABITY FREDERICK A
IPC: G01N1/00
Filed: 1991-01-28
Abstract: To meter liquid pumped from a well through a long tube, changes in the strain in a portion of the tube carrying the liquid are measured and used to determine when the liquid has reached the portion.      Pumping cycles are counted to determine the amount of liquid that flows past the portion. The determination is based on an increase in the amplitude of the pulses indicating liquid is approaching the pump. Gaps in the pulses may be sensed and accounted for in the measurements.

Abstract: An information reproduction apparatus in provided with supporting means for supporting a recording medium.   A drive source, for moving the recording medium, is located between an initial insertion position and a reproduction position by driving said supporting means.  Transmission means is included for transmitting the driving force of said  drive  source  to  said  supporting  means  plus retraction  means,  operable  to  force  a  transmission element to retract from said transmission means.   The transmission  element  is  a  part  of  said  transmission means.   Motion means  operable  to  force  the  recording medium to move from the  reproduction position to the initial insertion position under the condition that said transmission element is not engaged in said transmission means, so that in forcibly moving said supporting means, when the drive is out of operation, said supporting means are  released  from  the  drive  force  by means  of  said retraction means,  thereby freeing the supporting means from the resistance force of the drive force.  However, under normal operation, the said transmission element is returned to the said driving force transmitting path, thereby stopping inconvenience to the operation.

IPC: B60N2/235
Filed: 1991-04-24
Abstract: A vehicular  seat back recliner hinge comprises first and second hinged members that are mutually rotatably arranged about a common pivot. The first member has a gear rack arranged thereon which is adapted to be engaged by a pinion spur gear.   The pinion  spur gear is  fixed on an adjacent  ratchet  wheel  spur  gear  in  mutually  dependent rotatable relation about a common concentric shaft secured on a  second  hinged  member.    A  selected  one  of the above-mentioned shaft and pivot are eccentrically mounted on a rotatable bushing arranged on a corresponding one of the members.  The bushing is operable to selectively position the pinion spur gear and the rack in first mutually proximal and second mutually spaced positions.  A locking pawl arranged on a second of the members is adapted to lockingly engaged with and unlockingly disengage from the ratchet wheel spur gear, and the locking pawl is operably positionable in selected first locking and second unlocking positions corresponding to concurrent first mutually proximal and second mutually spaced positions of the rack and pinion mentioned above.   In this way, the backlash between the rack and pinion is reduced when the locking pawl,  the ratchet wheel spur gear,  the pinion spur gear, and the rack are serially engaged in mutually secured relation to resist relative rotation between the two hinged members, about their common pivot.  In addition, this arrangement permits  backlash  to be  increased between the pinion  spur  gear  and  the  rack when the  locking pawl  is serially disengaged from the  ratchet wheel spur gear,  in order to ease the relative rotation of the two hinged members about their common pivot.

IPC: B41F1/42
Filed: 1991-05-30
Abstract: An ink tray has been improved to include a plurality of channel ribs formed on the bottom surface.  The rib ends are spaced apart from the ink tray side walls.  An ink pad is supported in the ink tray above the channels such that ink directed through the channels is absorbed by the ink pad.  Replenishing ink is directed into the ink tray and caused to collect at one end of a first group of channel ribs and thereafter uniformly between each channel rib of the first group.  The displaced ink is then caused to uniformly travel between a second group of channel ribs and exit the ink tray.  The travel path of the ink allows for even absorption of ink by the ink pad and the removal of excess ink from the ink tray.

Abstract: A  service  network  has  several  computer  systems connected  together.   A  computer  system  can  either  be  a "Service Requestor"  (SR),  a "Service Provider"  (SP),  or a hybrid of the two,  a "Service Provider/Requestor"  (SP/R). The service network is built by an enrollment process that adds computer systems into the service network.  A SP (or SP/R acting as an SP) already in the network can initiate the enrollment of an SR (or SP/R acting as an SR) into the network.   In addition, a SR (or SP/R acting as an SR) can initiate a request for enrollment into the network. If such a request is initiated, it must be approved automatically or with human intervention.
