Patent CA-2032652-A1 (CA)
Inventor: HOETZL MAX
IPC: C21D1/773
Filed: 1990-12-19
Abstract: An improved industrial furnace employing a new and unique heat transfer arrangement is disclosed. The furnace is a closed end cylindrical chamber with a circular, concentrically positioned plate dividing one side of the furnace into a fan chamber containing a fan and the other side of the furnace into a heat treat chamber containing the work.      The plate has a central under-pressure opening and its outer circular edge is spaced from the cylindrical wall to define an annular space which is non-orificing. Fan rotation in the fan chamber produces an annulus of wind mass swirling at high circumferential speed which axially travels through the non-orificing space towards the closed end of the heat treat chamber at slow speed. Heating elements extend through the non-orificing space into the heat transfer chamber and are constantly impinged by the swirling annulus wind mass to effect good heat transfer therewith. The under-pressure opening causes the heated wind to contact the work before it is drawn into the under-pressure opening for recirculation.      An incineration track is provided in the furnace insulation for incinerating the furnace flue products while also heating the wind mass.

Title: Dissolving gas in a liquid
Inventor: FITZPATRICK NICHOLAS B
IPC: B67D1/00
Filed: 1991-03-11
Abstract: ABSTRACT DISSOLVING GAS IN A LIQUID   Carbonated ale is pumped by pump 50 through a device 52 for dissolving a mixture of carbon dioxide and nitrogen therein.  A resulting turbulent stream of ale containing bubbles of nitrogen and carbon dioxide flows through a chiller 54.  The ale leaves the chiller 54 in the form of a foam.  The foam is allowed to subside in a tank 56 in which the ale is held under a nitrogen pressure for at least ten minutes.  The ale substantially free of foam is passed to a filler 64 from which it is charged into flexible, thin-walled cans which are then closed.  In each can, after its closure, dissolved gas comes out of solution to create therein a superatmospheric internal pressure that resists deformation of its walls during normal handling.

Patent CA-2042410-A1 (CA)
Title: Composite material
Inventor: VANDEN BROECK MARC
IPC: B29C70/08
Filed: 1990-09-26
Abstract: This material comprises a thermosetting resin matrix containing layers of carbon filaments. Given the high modulus of elasticity of these filaments, they cannot expand during the thermoforming of the composite material. Furthermore, these filaments can be wetted by the resin only with relative difficulty, so that thermoforming causes the composite material to delaminate. For this reason, an open-pored, compressible intermediate layer with a low modulus of elasticity is intercalated between two layers of the reinforcing filament material. This intermediate layer has excellent grip on the resin and can absorb tensile and compressive stress by virtue of its compressibility.

IPC: F41G7/32
Filed: 1992-01-24
Abstract: LINEAR PAYOUT LEADER HOLDER                        ABSTRACT A linear optical fiber waveguide dispenser (10) comprising a linear payout leader holder (15) including an optical fiber waveguide having an unjacketed portion (16) and leader (17) comprising a coiled jacketed portion disposed within a housing (11). The housing (11) has an exit aperture (14) through which the jacketed fiber waveguide protrudes. A fiber optic connector (18) is connected onto the end of the jacketed portion of the waveguide. The linear dispenser (10) accommodates the leader (17) without having to increase the size of the payout helix generated thereby. The linear payout leader holder (15) may be used with a balloon assisted dispenser that has its helix sufficiently dampened to create a linear payout. It allows a strengthened leader (17) to be coiled inside the dispenser (10), an arrangement that would not normally fit into the exit of a conventional linear payout dispenser. Also, in situations where there is the need for the fiber to payout close to the dispenser (10), the linear payout leader holder (15) provides a smooth nonabrasive mechanism to accomplish this. Payouts with a helix as small as four fiber waveguide diameters are achievable using the present invention, and the waveguide is protected during the high stress payout initiation phase. A plurality of single pylon launchers (20a-20d) having dual payout capability are provided and incorporate a payout initiation system with the use of the present invention and a balloon assisted dispenser (10).

Title: Detection and evacuation of atmospheric pollutants from a confined work place
Inventor: KISER THOMAS E
IPC: F24F11/02
Filed: 1992-02-03
Abstract: A system for maintaining atmospheric conditions in an enclosed building within desired parameters and rapidly evacuating abnormally high amounts of airborne pollutants from localized areas of the building is disclosed.      Conditioned air, including sufficient outside air, is continuously admitted to the building interior from a plurality of air handling units disposed about the building to maintain the interior of the building under a slight positive pressure throughout. The air handling units, at least in areas where concentrations of airborne contaminants are generated include, in addition to outside air and building air inlets and a building air outlet, an outlet exhausting to the outside. Sensors and/or scanning units located throughout the building monitor various atmospheric conditions and transmit signals indicative of the noted conditions to a central computer. The computer, in turn, compares the observed conditions to predetermined desired conditions and controls the air handling units as necessary to maintain the conditions within desired parameters. When an abnormal airborne pollutant condition is noted in a particular area, the computer initiates a sequence of steps to place the pertinent air handling unit or units in an evacuation or dump made. The outside air inlet and building air outlets are closed and the building return air inlet and exhaust outlet are opened so that contaminated air is withdrawn from the region and exhausted to the outside. When the pollutant level in the area again falls within predetermined parameters, the air handling unit or units return to normal operation.
