IPC: C07K16/00
Filed: 1987-07-14
Abstract: A murine monoclonal antibody which selectively binds to the determinant site or specific epitope of glycophorin A exposed on the membrane of the erythrocyte and does not bind to other glycophorins. The monoclonal antibody is coated on a microsphere or substrate of a suitable monodispersed variety and utilized in a separation procedure for recovery of white blood cell subsets without lysing of erythrocytes. The bound microspheres are recovered without adverse depletion of the white blood cell population of the sample. The microsphere or bead-to-cell ratio employed is most acceptable for commercial applications of the invention. The invention thus enables accurate assaying of white blood cell subsets in circulating peripheral blood without resorting to lysing of erythrocytes.

Title: Non-destructive evaluation of structural members
Inventor: PELLERIN ROY F
IPC: G01N29/04
Filed: 1990-05-30
Granted: 2000-05-16
Abstract: Disclosed are testing apparatus and methods for estimating mechanical properties of nonhomogeneous materials, such as lumber and other wood materials and composite materials, particularly elongated slender members. The testing is appropriate for estimation of tensile and bending strength, tensile and bending moduli of elasticity and possibly other mechanical properties. The testing apparatus include a test specimen support which holds the specimen during testing in a manner which minimizes attenuation of the stress wave which is intentionally generated in the specimen to help predict the mechanical properties. The specimen supports also preferably include means for weighing the specimen which is combined with size information gathered through an optical scanning system thereby allowing the density to be obtained automatically. The specimens are impacted to produce a moving stress wave which is advantageously a longitudinal stress wave which moves longitudinally through the elongated slender members being reflected within the member preferably a number of times. The amplitude of the moving reflected stress wave is sensing with respect to time to allow the velocity and attenuation rate of the stress wave to be determined. The information is preferably communicated to a computer which automatically processes the sensed information and compares it to preprogrammed parameters which allow the accurate estimation of one or more of the predictable mechanical properties. The tested specimens are advantageously sorted according to the mechanical properties or appropriately marked to indicate the grade, strength or other appropriate measure of value of the specimen.

Title: Peristaltic pump with mechanism for maintaining linear flow
Inventor: IRVIN RONALD D
IPC: A61M1/10
Filed: 1990-07-11
Granted: 1993-07-13
Abstract: ABSTRACT A  linear  peristaltic  pump  includes  a  mechanism  for maintaining linear flow of fluid through an I.V.  tube.   The mechanism comprises  a  casing  carrying  a  rotatable  camshaft having  a  plurality  of  cams  spaced  therealong  in  helical arrangement  and  a  plurality  of  fingers  coupled  to  the camshaft.    A  housing  for  establishing  linear  reciprocal movement of the fingers in response to rotation of the shaft establishes  a  moving  zone  of  occlusion  along  a  tube  held against  the  fingers.    Aligning  means  are  included  for establishing an axis  of  rotation  of  the camshaft which  is slightly tilted with respect to the tube.  This is accomplished by raising or lowering the upstream or the downstream end of the camshaft to prevent unwanted pressure from building up in the tube to reduce pulsatile flow and maintain linear flow. The  aligning  mechanism  comprises  a  generally  cylindrical bushing having an eccentric hole therethrough for carrying the hinged connection between the casing and the housing.   The bushing has a slot therethrough for adjustably rotating the bushing for adjusting the amount of tilt.  The adjustment can take place during operation of  the pump, having a pressure sensor against the tube, to achieve the optimal positioning of the camshaft depending on the tolerances of the pump mechanism to establish linear flow of fluid through the tube.

Title: Fast packet and frequency switch
Inventor: DANIELE ANTONELLA
IPC: H04B10/291
Filed: 1990-08-01
Granted: 1998-04-28
Abstract: A fast packet and frequency switch has inputs and outputs connected to optical fibres, each accommodating a number of different wavelength optical carriers, modulated by serial information flows organized into packets.  These packets are phase-realigned and their labels are converted by an input block under control of external processors designed to set up and tear down connections.  The optical carriers allocated to packets are frequency converted, and the packets are recombined onto a single fibre by a passive recombination network for storage in an optical loop memory formed by  an  optical  fibre  delay  line.   Packets  are extracted as their assigned outputs and output carrier frequencies become available, and the combined packets are again frequency converted using converters driven so that frequencies not corresponding to the assigned outputs and output carriers are discarded.  The remaining packets are recombined at the outputs.

Title: Improvements in or relating to the control of linear motors
Inventor: KELLY HUGH-PETER GRANVILLE
IPC: G01P3/52
Filed: 1990-09-05
Granted: 2000-05-30
Abstract: A linear motor comprises a stator and an armature provided, respectively, with a set of spaced apart permanent magnets and a set of drive coils (not shown). The permanent magnets produce a radial magnetic field whose strength varies periodically along the length of the stator . The field strength is to derive speed and position signals by means of detectors constituted by field coils             and Hall Effect sensors.      The periodic variation of the field strength is compensated for in the case of the field coils by staggering their phases along the length of the armature and selectively combining their outputs; in the case of the Hall Effect sensors, the periodical variation is used to derive positional information.

Title: Tdm system and method having time slot request signaling
Inventor: HAGIRAHIM HASSAN
IPC: H04L12/28
Filed: 1991-04-24
Granted: 1996-01-09
Abstract: A multi-user Time Division Multiplex (TDM) system includes a plurality of stations connected by one or more unidirectional data buses. A "queue of request" (QR) counter is added to each station having destination slot release capability. The QR count indicates how many outstanding requests there are for idle time slots from "downstream" stations. The QR counter is incremented when a station becomes active (i.e., has a data transmit request). The QR counter is decremented when a busy time slot is released to an idle time slot condition, as long as outstanding requests exist from downstream stations. When the QR count is negative (indicating more idle slots than requests), a station erases a request signal received from a downstream station. When the QR count is positive (more requeststhan idle slots), a station writes an additional request signal to upstream stations. When the QR count is zero, request signals are not altered by a station. A separate QR counter and associated circuitry is utilized by each unidrectional bus of the TDM system.

Title: Microoptical sensor
Inventor: FATTINGER CHRISTOF
IPC: G01N21/27
Filed: 1991-04-29
Granted: 2002-07-02
Abstract: A microoptical method and a corresponding sensor for detecting chemical substances in a sample. The sample is brought into contact with the waveguiding layer of a planar optical waveguide. Coherent light is coupled into the waveguiding layer, propagates therein as a guided wave, and the latter is decoupled from the waveguiding layer. Both, coupling and decoupling of the light wave guided in the planar waveguide are effected by means of a multi-diffractive grating situated in the plane of the layer, i.e. a grating structure comprising two or more fundamental frequency components for in-coupling and out-coupling, respectively. The multi-diffractive grating coupler results in a directional separation of decoupled light from reflected, transmitted and directly diffracted sub-beams, respectively. This makes possible a background-free detection of guided light decoupled from the waveguiding layer, although the regions on the waveguiding layer in which coupling and decoupling of the guided light wave take place overlap in part.
