Patent CA-1286197-C (CA)

Granted: 1991-07-16
Abstract: ABSTRACT     A single stacked cam bearing surface is used to actuate several cam followers in such manner that the cam bearing surface can move past one or more cam followers without actuation thereof but can be caused to stop at and actuate any desired cam follower. A stacked disc-cam bearing surface of the improved cam actuator assembly of the present invention includes rotatable cam sub-assembly discs each having a surface well. The plurality of cam followers that bear against the bearing surface are selectively actuated by a controlled positioning of the cam sub-assembly discs that radially aligns the wells of the bearing surface with a selected cam follower. During a controlled rotation of the cam assemblies through an angular position of an intermediate cam follower, the wells of the sub-assembly discs of the cam bearing surface are radially mis-aligned, and thereby fail to actuate the cam follower during rotation through an intermediate angular position. The wells are aligned at a cam follower to be activated by a back and forth motion of the discs with the wells positioned under the followers.

Filed: 1988-01-28
Granted: 1991-03-26
Abstract: ABSTRACT         A digital switching network is disclosed in which paths can be preset from any inlet to any outlet either for circuit-switched connections or for packet-switched messages (packets), as required.  At any point in time, the paths preset for the packet.-switched messages form a network whose nodes lie in the switching facilities of the switching network.  The switching facilities contain the functional units required to switch each data packet on the path preset for it.  This makes it possible to dynamically divide a single switching network into a circuit-switching network and a packet-switching network as required.

Abstract: ABSTRACT     In accordance with an embodiment  of  the present invention, a   substantially   rigid,    multi-well, self-pipetting    device    for    use    in   chemical, immunochemical    and    microorganism    analysis    is provided.  The device includes a substantially rigid, substantially  planar  frame having,  in  operational orientation, a front face, a back face, a top edge and a bottom edge.  A plurality of test wells are disposed within the device between the front face and the back face,  usually in a linear array.  A filling manifold is located within the device.  The filling manifold is in  fluid  communication with  each of  the  test wells through  a  filling  passageway.   A  docking  port  is provided in the device which is adapted for receiving a  reservoir  holding  a  fluid  specimen.   The  docking port  is  disposed  on  a  peripheral  surface  of  the device.   The docking port  is  in  fluid communication with the filling manifold through a filling port and a filling channel disposed within the device.  With the device in its operational orientation, the test wells, filling channel, filling manifold and filling port are located at a level lower than the surface of the fluid in the reservoir.     The  device  has  a  vent  control  system,  also  in fluid  communication  with  the  test  wells,  which  is comprised of one or more vent manifolds, and/or valves to a vent manifold, and/or one or more vent holes or other passages to the ambient atmosphere.  These vent holes, if present, are temporarily closed by a film or other  means.   With  the  device  in  its  operational position,  the vent manifold and/or vent holes of the vent  control  system  are  positioned  higher  than  the surface of the fluid in the reservoir.  The test wells are  connected  to  the  filling manifold  and the  vent control system according to the filling sequence.  The reservoir is also connected to the vent control system through a  vent port  and a  vent channel.   The fluid specimen in the reservoir therefore flows down to the filling manifold by gravity and fills the test wells vented to the reservoir or to the ambient atmosphere.

Title: Polyhydroxyalkane/aromatic diamine chain extenders
Inventor: PRESSWOOD JOHN K
IPC: C08G18/32
Filed: 1988-08-15
Granted: 1995-02-21
Abstract: Blends of 90-99 mol % of a polyhydroxyalkane containing 2-6 carbons and 2-3 hydroxyl groups and 1-10 mol % of an aromatic diamine having a pKb value greater than 11.3 are useful as chain extenders for polyurethanes derived from diphenylmethanediisocyanate (MDI) prepoly-mers.  Their use overcomes the sensitivity to stoichio-metry common to MDI prepolymer/polyhydroxyalkane systems and leads to the formation of cast elastomers having better green strength and a shorter demold time.  The preferred blends are blends of 1,4-butanediol and di(alkylthio)toluenediamines.

Title: Off board ink supply system and method for an ink jet printer
Inventor: CHAN CHOR S
IPC: B41J2/175
Filed: 1988-10-03
Granted: 1992-10-20
Abstract: Abstract A process and system for supplying ink to an ink jet pen wherein an off board ink supply is provided remote from the pen, and ink is fed from this supply to the pen by capillary action created during an ink jet printing operation.  The pen includes a porous storage medium which is initially filled with ink at a slightly negative head.  However, this negative head increases during ink depletion from the storage medium and provides the capillary forces necessary to pull ink into the storage medium from the off board ink supply.  The driving energy for this action is provided by current drive to a thin film printhead of the pen, thus rendering the printhead multi-functional in purpose and simplifying the ink supply apparatus therefor.  The use of an intermediate porous storage medium enables the ink supply system to accommodate large rates of changes in ink demand from the pen while still affording the user with a large ink capacity system in which disposable pens may be readily and easily replaced in a user-friendly operation.

Abstract: Abstract The invention relates to a method and means for automatic analysis for determining the size distribution of particles and deviation from desired shape and colour.  The method includes collection of particle samples and generation of a particle curtain in monolayer form. It is formed by taking particles through a silo whose distance (a) to a vibrating plate positioned below has a length relative to the distance (b) between the outer edge of the plate and the centre line of the silo that is large enough for the particles flowing out of the silo and down onto the plate and out over its edge to form an angle .alpha. with the horizontal plane. The angle .alpha. is  95 -  50  %  of  the  sliding  angle of the particulate material. The particle curtain is lit up and the silhouette of the particles therein is recorded and analyzed and pre-sented in at least one place. The means includes sampler (1) plus silo (3) with at least one level sensor (4) to record the level of particles in the silo (3) and to give a signal to sampler (1). The silo (3) has a vertically displaceable extension (6) at its outlet opening. The lower part of the extension (6) is at a distance a from a vibrating plate (8).
