Patent CA-2071732-A1 (CA)
Inventor: SAKATA TAKASHI
IPC: G01N33/50
Filed: 1992-06-19
Abstract: A hematological specimen for classifying and counting leukocytes with a flow cytometer is prepared. A sample to be assayed is prepared by eliminating influences of erythrocytes from a hematological sample without changing leukocytes morphologically by adding a first aqueous solution of a low osmotic pressure comprising a buffer for adjusting the pH value within an acidic region and a second aqueous solution comprising an osmolarity compensating agent and a buffer for giving a pH value suitable for staining, optionally further adding a salt, which dissociates into ions in aqueous solutions so as to control the electrical conductivity of the aqueous solution at a preferable level, while damaging the cell membranes of erythroblasts contained in said sample; and staining the leukocytes with at least four dyes including Astrazon Yellow 3G and Neutral Red.      Thus leukocytes contained in the hematological sample can be classified at least eight groups two each comprising immature granulocytes, one comprising erythroblasts, one comprising basophils, one comprising eosinophils, one comprising lymphocytes, one comprising monocytes and one comprising-neutrophils, or nine groups involving one comprising blasts in addition to the above-mentioned eight groups, by assaying a single specimen with a flow cytometer.

Title: Channel impulse response estimator for a system having a rapidly fluctuating channel characteristic
Inventor: MUTO HIROYASU
IPC: H04L25/03
Filed: 1992-08-24
Abstract: In a channel impulse response estimator,  a local preamble generator generates a local preamble signal identical with a transmission preamble signal in a received signal.  A preamble detector detects the transmission preamble signal in an estimated sequence signal to produce a preamble detection signal.  Responsive to the preamble detection signal, a sequence selector selects one of the local preamble signal and the estimated sequence signal as a selected sequence signal which is supplied to a re-modulator.   Responsive to the preamble detection signal, a step-size generator generates one of first and second step-size signals as a selected step-size signal which is supplied to a tap coefficient producer.

Abstract: PATENT     COATED CERAMIC FIBER SYSTEM                    ABSTRACT       A ceramic fiber is provided with a plurality of coatings to define a system useful in making composite articles in the manufacture of which the fiber experiences applied stress such as thermal shock.  For example, such applied stress occurs in molten metal spraying about fibers to provide a metal matrix composite.  The fiber, as a core, is provided with a first coating layer tightly bonded to a lateral surface of the fiber and has a first structure.  A second coating layer is then deposited on the first layer and has a second structure different from the first structure thereby defining an interface between the coating layers which is a debonding discontinuity zone sufficiently weak to enable separation of the layers as a result of applied stress, such as introduced by a thermal shock experience.

Title: Stacking of flexible planar articles
Inventor: FREEMAN ROSS A
IPC: B65H31/06
Filed: 1993-07-20
Abstract: ABSTRACT OF THE DISCLOSURE      Short multi-ply business forms, or other flexible planar articles, are stacked with a vertical orientation in a horizontally elongated stack.  The forms are conveyed in a first horizontal direction, then deflected by a deflecting roller and conveyor belts to move toward a generally vertical orientation, and driven vertically into contact with a depth stop, so that they have a vertical orientation and the first form in a stack is against a backstop.  The backstop is moved intermittently in the horizontal first direction to accommodate further forms in the stack.  A conveyor for moving the forms vertically is mounted for pivotal movement about a generally horizontal axis, which movement is sensed by a sensor which in turn, through a controller and motor, effects intermittent movement of the backstop.  The depth stop may be adjusted to accommodate forms of different depths, and the position of the horizontal axis about which the second conveyor pivots may also be adjusted.  The pivoting vertical conveyor applies a packing force against the forms in the stack, and its center of gravity is between its pivot axis and the stack at all times.

Patent CA-2106531-A1 (CA)
Inventor: FACCIOLI GIOVANNI
IPC: A61B17/00
Filed: 1993-09-20
Abstract: A jig is detachably secured to the proximal end of an installed intramedullary nail having a transverse bolt hole near the distal end of the nail.  The jig comprises an offsetting arm which so mounts an elongate template as to be movable in a geometric plane substantially parallel to the nail.  A guide bore near the distal end of the template is on an axis perpendicular to the geometric plane.  When the jig is chucked to the nail, the axis of the guide bore of the template is parallel to the axis of the bolt hole of the nail, and both the guide-bore axis and the bolt-hole axis are at identical distance from the offsetting arm.  The distal end of the template is adapted to removably mount a metal-detector establishing a magnetic-field about a directional axis, such that the metal-detector can be selectively moved or positioned on one and then the other side of a central position in which the template is strictly parallel to the nail.  Template positions noted for equal detector signals on opposite sides of the central position enable determination of the central position and therefore the location at which the template guide bore is in axial alignment with the bolt hole of the nail.
