Patent CA-2109837-A1 (CA)
Inventor: PRINCE PAUL R
IPC: A61M1/30
Filed: 1991-06-26
Abstract: A simplified fluid separation method and device usable for various apheresis procedures, including plasmapheresis.  At least one pump is utilized to draw a first fluid (e.g. whole blood) into a separation device.  The separation device then operates to separate the fluid (e.g. whole blood) into first and second fluid fractions (e.g. a cell concentrate and blood plasma).  The first and second fluid fractions are pumped from the separation device to separation first and second fluid fraction containers, both of which are positioned on a single weighing device, such as an electronic load cell.  At least one of the fluid fractions is subsequently removed from its fluid fraction container and returned to the human subject or other fluid source.  Weights recorded by the single weighing device are then utilized to calculate the actual weights of fluid and/or fluid fractions pumped by at least one pump during the procedure.  Such actual weights of fluid and/or fluid fractions are then utilized to calculate new pump flow constants, thereby enabling the calibration of the pump(s) to be corrected, on the basis of such new pump flow constants, prior to subsequent utilization of the pump(s) for pumping the fluid and/or fluid fractions.  The single weighing device may also be utilized to monitor the weight change or rate of weight change occurring as the fluid fractions are pumped into and/or out of the fluid fraction containers, thereby providing a means for monitoring and verifying the pressures and flow rates within the system.
Patent CA-2111552-A1 (CA)
Inventor: LEWIS SCOTT C
IPC: C12Q1/6816
Filed: 1993-12-15
Abstract: A method and apparatus for determining a plurality of substances or constituents of a specimen sample includes the steps of placing a single specimen sample in a reaction vessel or test tube and adding at least two reagents to the reaction vessel to form a detectable product and then initiating a reaction within the vessel and provide an emission of light energy in a predetermined spectral range. The reaction vessel is disposed in a chamber of a housing and a plurality of detector assemblies are disposed about the housing with portions of the detector assemblies disposed through the housing and exposed to the reaction vessel. Each of the detector assemblies receives a portion of the light emission and feeds such portion to a detector. Each of the detectors detect the existence of light emissions in one of a plurality of spectral ranges and feeds that information to processing circuitry to provide data for determining the presence of a specific specimen substance(s) or constituent(s) based upon the detected luminescence.

Title: Apparatus for driving a wobbling body
Inventor: MEYER PIO
IPC: B01F11/00
Filed: 1993-05-27
Abstract: Summary A tumbling,  oloid hollow body  (4)  is placed on freely moving rollers (51) that cause its tumbling motion to receive materials. The tumbling motion is forced by the fact that the trace points of the axis of a hollow shaft (6) piercing the hollow body (4) in its longitudinal axis are forced onto oval paths by two planes parallel to each other that are upright and are defined by a frame (11). Each of these frames (11) carries a vertically moveable and driven slide (60)  forming itself a guiding element for a horizontally moveable and driven slide (61). Each of these horizontally moveable slides (61) holds a ball (62), pierced by the shaft (6), forming the bearing and guiding element for it. The slides (60, 61) are driven by a control  (63)  that stores the position-time-speed profile comparable to the tumbling motion. The tumbling hollow body (4) has a closeable opening (5) for the addition and removal of mixing material. If the shaft (6) is hollow, mixing materials can be added and removed during the tumbling operation by means of rotary passages on both ends of the hollow shaft (6).          (Fig. 6)

Title: Method and apparatus for placing discrete parts onto a moving web
Inventor: RAJALA GREGORY J
IPC: B65H37/04
Filed: 1994-05-06
Abstract: A method and apparatus for receiving discrete parts travelling at a first speed and applying the parts to a substrate web travelling at a second speed includes at least one rotatable transferring mechanism, a driving mechanism and at least one driven mechanism. The rotatable transferring mechanism is connected to an output shaft and moves along an orbital path through a receiving zone where the parts are received and an application zone where the parts are applied to the substrate web. The driving mechanism utilizes at least one rotatable noncircular drive gear connected to an input shaft to transmit rotational energy to the driven mechanism. The driven mechanism utilizes at least one rotatable noncircular driven gear connected to the output shaft or to a jackshaft to accept the rotational energy from the driving mechanism and transmit the energy to the transferring mechanism. The input shaft and output shaft or, in the alternative, jackshaft are offset such that the noncircular drive gear is configured to engage and rotate the noncircular driven gear which, in turn, rotates the rotatable transferring mechanism.

IPC: F16B19/10
Filed: 1994-06-17
Abstract: ABSTRACT OF THE DISCLOSURE     A mandrel (15) inserted in a rivet body (11) to form a blind rivet (10) has a head (17) extending from a rod-shaped mandrel body (16).     The head formed to have a plane top surface (18) perpendicular to the mandrel body, has a diameter 'D' almost equal to the outer diameter of rivet body, and a height 'H' of 80 % to 100 % of the mandrel body's diameter 'd'.      A frustum-shaped low protrusion (19) formed centrally of and on the top sur-face has an upper surface (20) of a diameter 'd1' slight-ly greater than the diameter 'd'.    A conical or other-wise curved surface (21) of the mandrel head applies a force to an open end of rivet body (11) in a self-centri-petal manner when the force is imparted to the mandrel body to caulk or deform the open end, so that a uniform caulking is effected, with the head being retained not to slip off the caulked rivet body whose length is notice-ably reduced.     An apparatus, if installed in a nailery machine, enables the easy production of the mandrel in the same manner as the prior art mandrels.

Abstract: A twin beam parallelogram-type lift axle suspension system includes  a bi-directional  airlift  spring having opposite end plates at either end thereof located between two parallel control arms wherein expansion of the air spring  pivots  the  upper  and  lower  control  arms  with respect to a frame bracket thereby lifting an axle and wheels  attached thereto  from engagement with the  road surface.  The end plates of the bi-directional air spring move  about  equally  in  opposite  directions  and  remain substantially   parallel   to   one   another   throughout expansion and contraction of the  air  spring so  as  to about equally distribute forces of expansion of the air spring between the upper and lower control arms.   The system of the instant invention also  includes  a shock absorber having one end attached to the upper control arm and another end attached to the lower control arm so as to locate the shock absorber forward of the axle thereby minimizing shock travel and maximizing shock life.   The upper control arm is pivotally connected to an axle seat by a bolt  including  an eccentric  cam mechanism which allows one to adjust the caster angle of the axle when the need arises.
