Patent CA-2135849-A1 (CA)
Inventor: SHELTON K DAVID
IPC: G09F13/20
Filed: 1994-11-15
Abstract: A sign for selected alphanumeric or graphic sign display is constructed from a first translucent fluorescent plastic sheet (FPS) having area dimensions selected for a sign display and a thickness for structural support of the sign and for conducting light along the plane of the FPS.  A relatively thin reflective layer is formed on one side of the FPS.  The reflective layer is substantially opaque and preferably white.  A relatively thin decorative layer is formed over the reflective layer and is selected to provide a desired sign decor.  Grooves are cut in the FPS in the pattern of the selected alphanumeric or graphic sign display.  The grooves are cut in the FPS through the decorative and reflective layers and penetrate  into the FPS in the range of 25% to 75% of the thickness of the FPS.  The grooves are cut with angled surfaces forming angles between parallel and perpendicular angles to the FPS so that the FPS conducts ambient natural or artificial light along the plane of the FPS and concentrates and transmits light at the angled surfaces for illuminating the selected alphanumeric or graphic sign display.  Grooves formed in the FPS are preferably substantially semicircular cross section.  The edges of the fluorescent plastic sheet can be formed with a bevel angle edge.  The signs are formed in a variety of sign configurations including boxes, enclosures, shades, covers, table top displays and sign displays generally.  A variety of aesthetic effects is achieved by incorporating other layers into the sign structure.

Title: Double slot selective mining system
Inventor: BUYENS MARC OCTAVE RENE GHISLA
IPC: B28D1/08
Filed: 1994-04-28
Abstract: The invention relates to a double slot wire sawing maching (26).  The characteristic feature of the machine is that is has a mobile chassis (34) with a driving arrangement (Figures 4 and 5, Figures 8 and 9) for simultaneously and independently driving two separate wire saws (30, 32). With independently driven wire saws (30, 32) it is possible to control the sawing operation in such a way that one wire saw is always directly over the other. This has been found to be of great importance in reducing the tendency of the wire saws to become jammed in the slots which they cut.

Title: Method and circuit arrangement for disturbance-free redirection of a message cell stream onto an alternate route
Inventor: EDMAIER BERNHARD
IPC: H04L12/56
Filed: 1995-05-09
Abstract: Within a cell-oriented communication network (ATMN), a message cell stream supplied to a switching equipment (CCa) located at the start of a path pair is duplicated by the switching equipment in response to a request.   The two message cell streams resulting therefrom are supplied to a central synchronization device (AS) allocated to the switching equipment (CCb) located at the end of the path pair, being supplied thereto separately via an active path (AP) and via an alternate path (EP) allocated thereto.   In the synchronization means, a synchronization of the two message cell streams ensues, while the message cell stream of the active path is being initially forwarded.   After this,  only the message cell stream of the alternate path is forwarded, upon disconnection of the central synchronization means from the transmission path.
Patent CA-2149225-A1 (CA)
Title: High-production rotary furnace steelmaking
Inventor: SHERWOOD WILLIAM LYON
IPC: C21B13/08
Filed: 1992-11-12
Abstract: The invention is a process for steelmaking in a rotary furnace from a solid metallic charge adapted to realize greatly in-creased heat transfer and melting rates and thereby greater steel production.  A hot liquid metal bath is maintained over the length of an oxy-fuel fired rotary furnace. Solid metallic scrap is continually introduced by way of a charge end opening into a melting zone, wherein the bath melting point temperature is depressed on the order of 300 degrees Celsius at the furnace charge end, by means of coincident additions of supplementary carbon into the melt. The effect is a multifold increase in temperature differen-tial between the flame temperature and the temperatures of the furnace walls and charge, with a proportionate increase in the quantity of heat transferred. In order to maintain this depressed temperature, a corresponding increased quantity of cold solid scrap is required to be charged into the melt and advanced along the furnace, according a dramatic production rate increase in relation to the prior art. The preferred embodiment provides an intermediate annular dam which substantially confines unmelted solid charge to the melting zone, over which melted metal overflows into an all-liquid refining and temperature-composition ad-justment zone preceding discharge, with overall firing and furnace interior gas flow countercurrent to the general charge move-ment, thus allowing the steel discharge temperature to be controlled independently of the heating rate. Other benefits include in-creased refractory life, less oxidation of charge and refractory constituents, and substantially less particulate and pollutants discharged in the process off-gas.

Title: Device and method for arresting a fall
Inventor: OLSON WAYNE L
IPC: A62B35/04
Filed: 1995-06-16
Abstract: A device for arresting the fall of an individual wherein a plurality of layers of a elongated webbing are wound on a drum so that when a fall occurs the weight of the fall is absorbed by compaction of the layers of the elongated webbing on the drum and the elongation of the portion of the elongated webbing unreeled from the drum.          Also, a locking mechanism is disclosed when a spring urges a pawl against a rotating surface having a cam until the speed of rotation of the cam overcomes the force of the spring and moves the pawl into engagement with a catch.  The cam moves the pawl into the engagement zone at lower than locking speeds and requires the normal action of the spring and pivot pin to pull the pawl out of the engagement zone before the tip of the sperrad engages it, thus providing a fail safe advantage.  In further embodiments, the device is attached to a body safety harness usually worn by a worker.

Title: Convection Cooling of Embankments
Inventor: GOERING DOUGLAS J
IPC: E01C3/06
Filed: 1995-07-14
Abstract: A roadway for use on permafrost terrain is described together with methods of construction, the roadway generally including a porous embankment and a pavement structure disposed on the top of the embankment.  The embankment has a desired vertical separation between the bottom and the top of the embankment and comprises material of sufficient permeability to allow buoyancy-driven pore air convection to occur within the embankment when an unstable density stratification exists therein.  This unstable density stratification occurs in the winter months when a temperature differential between the top of the embankment and the ground adjacent the bottom of the embankment exists, whereby the roadway promotes natural convection within the porous embankment which enhances heat removal from the embankment and underlying ground to preserve the permafrost layer throughout the year.
