Title: Paper sheet feeding apparatus
Inventor: GREEN RONALD J
IPC: B65H3/04
Filed: 1992-01-02
Abstract: Disclosed is a sheet feeder device including means for supporting a generally vertical stack of sheets. The supporting means include endless belts having an upper belt run position to extend across the bottom of the stack of sheets. A stationary gate forming member is provided which is positioned above the upper run of the belts and adjacent the forward side of the stack to define a nip which forms a gap between the gate forming member and the upper run for permitting the lowermost sheet of the stack to pass forwardly from the stack through the nip. The gate forming member is a cylindrical roll defining a central axis and an outer peripheral surface which is concentric to the central axis. The roll has a groove extending axially along the length thereof. An elastomeric bar is disposed in the groove, and the bar has a coefficient of friction which is higher than that of the material of the roll.  Also, the bar is sized so as to extend radially beyond the peripheral surface. This portion of the bar includes a rearwardly facing edge surface which extends generally along a tangent to the outer peripheral surface of the roll. In operation, the lowermost sheet is fed by the endless belts through the nip without engaging the bar and without significant frictional resistance, while the sheet immediately above the lowermost sheet engages the bar and is retarded in its advance by its engagement with the material of the bar.

Patent CA-2107969-A1 (CA)
Inventor: CHROSNY WOJCIECH M
IPC: B65H7/06
Filed: 1993-10-07
Abstract: A sheet processing apparatus, which may be a mailing machine, inserter or similar system for producing mail pieces or may be a copier or printer or the like. The system includes a control mechanism for reducing the likelihood of jams as sheets are fed through a sheet handling apparatus included in the system. Preferably the control mechanism will include a neural network trained to response to a characteristic signal generated by a sheet feeder as a sheet is input to the apparatus. After training the network will produce a control signal output for controlling the processing rate of the apparatus to reduce the rate if there is a likelihood that the input sheet will jam. The network may also produce an outstacking signal for diverting sheets, in extreme cases, for corrective action. The drive current of a motor used to output the sheet from a sheet feeder is monitored to provide the characteristic signal which is sampled an input to the network. And additional signal representative of an external condition, such as temperature or humidity or operating history may also be input to the network.

Patent CA-2114311-A1 (CA)
Inventor: WEE RICHARD K
IPC: C12N5/0781
Filed: 1991-11-25
Abstract: A human B-cell line (designated WB) was selectively cloned from peripheral blood of a healthy 48 year-old Chinese male by use of a serum-free defined medium. The in vivo pre-activated B-cells required an 8-week "incubation period" before large clusters of cells with apical cytoplasmic projections directed radially outwards became apparent, and their gradual proliferation was observed. Within a week, sufficient cell clusters predominate  to allow a 1:2 split twice weekly. Phase-contrast microscopy showed individual cells as 10u  to 20u  fusiforms  with  abundant  phase-dense granules.  By electron microscopy, each  cell revealed numerous inclusion bodies, mitochondria,  stratified rough endoplasmic reticulum (RER), carbohydrate inclusions, and a heterochromatic thick-rimmed, irregular large nucleus containing a prominent  nucleolus. These EBV-negative WB cells expressed the CD19 and CD20 pan-B antigens,  IgG, and activation markers DR, DQ, Leu 8, CD23,  CD25, CD38, and CD71. After 6 months of subculture, the cell line was adapted to culture in a protein-free RPMI 1640 medium. Interestingly,  the cells could sustain autonomous growth and replication in semi-suspension culture in the absence of any exogenous protein. Under electron microscopy, these  protein-independent  cells  exhibited  ringed  nuclei,  frequent  binucleism,  dense elongated mitochondria, and carbohydrate inclusions. In addition, there was abrogation of DR, DQ, Leu 8, CD23, CD25, CD38, and CD71. The conditioned medium (CM)  from either the serum-free or the protein-free WB culture contained two novel proteins, namely 21 and 53 kilodaltons  (Kd)  moeities  with  respective  necrotic  and  growth  bioactivity.  Hence, availability of  this  cell  line would allow for easy purification of  these important secretory proteins, and for the production of human monoclonal antibodies. Also,  further study of the cell line may provide the answer as to how cancer cells could gain autonomy in a milieu of apoptosis.     DESCRIPTION OF FIGURES     Figure 1. Transmission-electron micrograph of a representative WB cell showing inclusion bodies, stratified  rough  endoplasmic  reticulum  (RER),  and  a  heterochromatic  thicked-rimmed, irregular large nucleus with a prominent   nucleolus.

Filed: 1994-04-12
Abstract: It is possible to determine whether the correct business form parts have been properly provided in an outgoing package (e.g., mailing envelope) containing a plurality of parts, utilizing a magnetic detector capable of detecting magnetic toner within the package. Dense patterns of magnetic toner are imaged on portions of each of the business form parts, located at different positions on different parts. Then the parts are formed into a package (as by folding about fold lines into a self-contained mailer, or inserting into a mailing envelope), and the package is moved with respect to a magnetic detector. The magnetic detector senses the dense magnetic toner patterns within the package to determine whether all the correct parts are properly in the package by determining whether all business form parts in the package have the detectable magnetic toner indicia patterns on the predetermined portions. The dense patterns of magnetic toner are preferably in the form of solid toner rectangles disposed in a straight line configuration, and the package is moved in a straight line with respect to the detector. A multi-part business form is also provided, having dense patterns of magnetic toner and less dense alphanumeric indicia on the plural plies of the business form, which may be a self-contained mailer or parts inserted into a mailing envelope.

Title: Method for rejecting electrical interference from physiological measurements
Inventor: MCKOWN RUSSELL C
IPC: A61B5/308
Filed: 1993-01-28
Abstract: Methods and apparatus for eliminating the effects of electrosurgical interference on continuous, heat-based cardiac output measurements employing several procedures, including the steps of (1) supplying power via an isolation transformer (12) and carrier frequency to a catheter-mounted heating element (16); (2) measuring the voltage and current on the primary side (10) of the isolation transformer (12); (3) determining the voltage and current on the secondary side (14) of the transformer (12) on the basis of the measured primary side voltage and current; and (4) calculating the power delivered to and resistance of the catheter-mounted heater (16) on the basis of the secondary voltage and current. A  heater power waveform generated with this process will be substantially free of electrical interference due to electrosurgical devices. Then, a system transfer function may be produced via signal processing techniques which involve cross-correlating the heater power waveform with the blood temperature waveform. The system transfer function will be uncorrupted, even if the blood temperature waveform contains moderate electrical interference, since the heater power waveform is free of any correlated electrical interference.
