Patent CA-2060462-A1 (CA)
Title: Apparatus and method for timing distribution over an asynchronous ring
Inventor: FARLEIGH SCOTT E
IPC: H04J3/06
Filed: 1992-01-31
Abstract: An asynchronous, fiber optic, ring network includes a number of nodes where data enters and exits the network. Each of these nodes has its own clock to provide timing needed by equipment at that node. So that synchronous data can betransmitted between predetermined nodes, a master node provides timing information which may be used at any node to synchronize its clock. Timing information comprises the propagation delay around the ring (ring latency) as measured by the master node. This measure of propagation delay is transmitted bythe master node as an information packet available at all nodes. Synchronization of any other node with the master requires that the other node perform its own measurement of propagation delay, compare its measurement with that of the master node, and make adjustments to its own clock that tend to decrease the differencebetween these measurements.

Title: Battery charging system having logarithmic analog-to-digital converter with automatic scaling or analog signal
Inventor: GILMORE ALAN A
IPC: H02J7/02
Filed: 1992-02-10
Abstract: ABSTRACT OF THE DISCLOSURE     An  ultra-quick  charging  device  for  charging battery packs for an assortment of different appliances, such  as  power  tools,  having  a  wide  range  of  output voltages.  The charging device includes an AC to DC high current power supply circuit and  a microcomputer-based controller  circuit  for monitoring  the  voltage  of  the battery and converting from fast charge to trickle charge when the second inflection point in the battery voltage charge curve is detected.  In order to permit the device to charge battery packs  of different  rated voltages,  the device includes a logarithmic analog-to-digital converter circuit  having  a  selectable  prescaler  circuit  that attenuates the battery voltage signal.  The microcomputer is  programmed  to  automatically  set  the  appropriate attenuation level of the prescaler circuit at the outset of the charging cycle by assuming that the maximum voltage of the battery pack being charged will be less than or equal to 150 percent of its observed battery voltage following the initial settling period of the charge cycle.  In this manner the present invention is able to automatically fully charge battery packs ranging in voltage between 3 volts and 24 volts.

Title: A centrifugal separator for separating solids and recyclable fluids from a fliud mixture
Inventor: GINGRAS EARL
IPC: B04B1/02
Filed: 1992-08-21
Abstract: ABSTRACT OF THE DISCLOSURE        A centrifugal separator in which a wash fluid zone is formed within the confines of an annular weir, with excess wash fluids passing via a spillway to an excess wash fluid outlet.      Recyclable fluids are forced into a wash fluid/recyclable fluid interface on top of the wash fluid zone by centrifugal force with recyclable fluids being skimmed from the wash fluid/recyclable fluid interface through a recyclable fluid outlet.  Solids are propelled by centrifugal force outwardly toward interior sidewalls and washed down sloped interior sidewalls toward a solids outlet by wash fluids fed continuously in through a wash fluids inlet.  A rotating shaft is provided having a plurality of arms which extends to immediately adjacent the solids outlet.  The arms have paddle shaped extremities.  Upon rotation of the shaft the paddle shaped extremities are brought into communication with any solids accumulated immediately adjacent the solids outlet thereby preventing a build up of solids which could potentially cause a blockage of the solids outlet and propelling solids mixed with wash fluid out the solids outlet.

Patent CA-2077669-A1 (CA)
Inventor: CONOCHIE DAVID S
IPC: H05B6/02
Filed: 1991-03-05
Abstract: A furnace configuration is disclosed which is suitable for scale-up of heat transfer limited processes performed at high temperatures, e.g: carbothenmic reduction of transition metal or rare earth oxides. The furnace is inductively heated by external insulated coils (3) and the susceptor (2), preferably graphite rings, is placed within the charge (1) away from the outer surfaces of the charge (1). Consequently heat is transferred to the charge (1) in three dimensions and the process approaches completion before the insulation (4) is subjected to high temperatures. As a result of this three dimensional heat transfer, larger furnaces are possible within the heat transfer constraints of these high temperature processes and higher yields are obtained.

Title: Modular tubular extrusion head and a process for extruding tubular articles
Inventor: COYLE DENNIS J
IPC: B29C48/32
Filed: 1992-10-08
Abstract: MODULAR TUBULAR EXTRUSION HEAD AND A           PROCESS FOR EXTRUDING TUBULAR ARTICLES                 ABSTRACT OF THE DISCLOSURE A polymer resin extrusion head includes one or more annular extrusion modules in which a spiral channel means having one or more convolutions extends from a resin inlet on the periphery of the module to an annular extrusion outlet. Preferably, the channel means gradually opens into an annular frustoconical space leading to the extreusion outlet at the inner edge of the module. The spiral channel extends symmetrically around the extrusion module or modules in a manner so as to subject all of the extruded polymer flowing from the inlet to the extrusion outlet to substantially the same process conditions along the flow path. As a result, the polymer is distributed at the outlet with properties which are substantially symmetrical around the axis of the extrusion module or modules for all resin distributed to the outlet. It is preferable that the extrusion module or modules comprise a pair of mating annular members with central frustoconical portions having apexes with an axial dimension  greater than the axial dimension of the outer portions of the modules so as to form air spaces around each module including frustoconical air space portions to avoid direct heat transfer between adjacent modules.
