Patent CA-2045460-A1 (CA)
Inventor: KATO YUMIKO
IPC: H04L49/111
Filed: 1990-11-29
Abstract: The present invention relates to a system switching system in an exchange system in which an ATM switch for exchanging asynchronous transfer mode (ATM) cells is duplexed.  In order to switch between ATM switches accurately with drop-out and overlap of cells eliminated, at the input side of the ATM switches, a bit indicating active is inserted into the header of a cell from a transmission line for application to the switch in the active system and a bit indicating standby is inserted into the header of a cell for application to the switch in the standby system and, at the output side of the ATM switches, bits in the headers of cells output from respective switches are referred to and only active indicating cells are selected to be output to a transmission line.  Buffers for storing active indicating cells are provided at the outputs of the ATM switches, respectively.  At the time of switching between systems, cell input to the old active system is stopped, active indicating cells are stored in the buffer in the active system, and active indicating cells stored in the buffer in the new active system are output after all the active indicating cells in the old active system have been output.

Patent CA-2051463-A1 (CA)
IPC: B41F31/30
Filed: 1991-09-16
Abstract: In a printing press, a ductor assembly for transferring ink from a slowly rotating fountain roll to a rapidly rotating ink receiving roll includes a carriage and first and second idler rolls supported in counterrotating engagement on the carriage.  In one embodiment, the ductor assembly moves between a first position in which the first idler roll contacts and picks up ink from the fountain roll, and a second position in which the second idler roll contacts and transfers ink to the ink receiving roll.  The ductor assembly is driven to rotate at a speed intermediate the speeds of the fountain roll and the ink receiving roll, in a direction the same as the direction of rotation of the second idler roll about its own axis, and opposite to the direction of rotation of the first idler roll about its axis.  When the ductor assembly moves to the second position, the surface of the second idler roll which contacts the ink receiving roll is moving in the same direction as the surface of the ink receiving roll, and is moving with a speed about equal to the speed of the ink receiving roll.  This minimizes speed mismatch.  In another embodiment, the rotating ductor assembly is fixed in position and the ink receiving roll moves into and out of contact with the ductor assembly.

Title: Gravity assisted collection device
Inventor: COLUMBUS RICHARD L
IPC: B01L3/00
Filed: 1991-10-29
Abstract: GRAVITY ASSISTED COLLECTION DEVICE     Abstract of the Disclosure There are described a device and method constructed to collect a liquid into a device so that the liquid is first drawn in to an intermediate point by capillary attraction only, and then from that intermediate point further by gravity.  The device features two apertured portions connected at said intermediate point so as to be angled to each other. The means in the first portion that provide the capillary attraction through its aperture comprise preferably oppositely disposed surfaces spaced a distance no greater than that which will maintain capillary flow into that portion through the aperture; The means of the second portion that provide gravity flow further into the device from the intermediate point are a spacing of the opposed surfaces a distance effective to allow gravity to passively overcome any surface attraction caused by said opposed surfaces, and the inclination of that portion to drop below the horizontal plane extending from the intermediate point.

Title: Gear pump for a metered liquid dispensing system
Inventor: ASLIN DAVID J
IPC: G01F3/10
Filed: 1991-11-29
Abstract: ABSTRACT OF THE DISCLOSURE       A gear pump for use in a metered liquid dispensing system utilizes a pair of carbon graphite wear plates to increase pump vacuum or suction lift capabilities.  The wear plates are disposed on opposite sides of the pump spur gears and are biased against the sides of the gears to reduce internal pump clearances.  The biasing force is provided by a resilient O-ring positioned between a surface of the pump housing and one of the wear plates.  The gears are mounted for limited movement so the urging of the one wear plate is transferred through the gears to the other wear plate.  The gear pump is driven through a gear reducer unit by a reversible electric motor.  The use of a gear pump assures accurate metering of the amount of fluid delivered by the system.

Title: Deformable insulating panel for a goods-handling door, and a door including such a panel
Inventor: KRAEUTLER BERNARD
IPC: E06B3/48
Filed: 1992-11-06
Abstract: The invention relates to goods-handling doors for separating different spaces in factories or warehouses and comprising a curtain that can be raised by being wound up or by being folded up concertina-like. The curtain must be insulating both with respect to heat and with respect to noise, while nevertheless being transparent so that one vehicle can be seen from another if they approach the door from opposite sides. To make this possible, the invention proposes making the door of two airtight flexible skins that lie parallel to each other and that sandwich spreaders between each other, the spreaders being spaced apart so as to define intermediate spaces between the two skins, which spaces remain filled with air. The air then provides the required insulation, and providing the two skins are transparent, the door can be seen through.

Title: Mounting plate for fixing elastomeric grade crossing panels to ties
Inventor: DAVIS R ANDREW
IPC: E01B21/00
Filed: 1992-12-01
Abstract: MOUNTING PLATE FOR FIXING ELASTOMERIC     GRADE CROSSING PANELS TO TIES                         ABSTRACT A railroad grade crossing system comprises a plurality of plates that rest on selected ties.  The plates have two or more upstanding projections with threaded openings extending through them.  The plates are positioned at the intersections of adjacent elastomeric grade crossing panels that have recesses defined in their lower surfaces that receive the projections.  Bores extending through the panels coaxially with the recesses permit bolts to be installed through the panels into threaded engagement with the projections.  Since adjacent panels are attached to a common plate, they become inter-connected so that the weight of an entire crossing element will resist movement of the panels.  In a typical application there are three crossing elements; a gauge element between the rails, and a field crossing element between each rail and the adjacent roadway.  Typically, the gauge panels only extend half-way between the rails so that each gauge plate is coupled to the inner corner of four adjacent gauge panels.  A locking panel, having wings which fit over the tie, is located at the center of each crossing element to facilitate installation.  An end restraint, affixed to a tie at each end of each crossing element, ensures that there is no movement of the cross-ing element along the rails and prevents lifting of the free end of the terminal crossing panel.
