Patent CA-2244283-A1 (CA)
Title: Continuous press for making particle board
Inventor: SCHUERMANN KLAUS
IPC: B27N3/24
Filed: 1998-09-14
Abstract: A press for pressing a mat into a thin panel has a press frame, upper and lower press plates on the frame, upper and lower press belts having confronting lower and upper stretches defining a press gap extending in a horizontal and longitudinal transport direction and respectively running below and above the upper and lower press plates, respective arrays of rollers between each press plate and the respective stretch, and upper and lower flexible intake plates juxtaposed respectively above and below upstream ends of the lower and upper stretches of the belts and defining therewith an intake mouth flaring upstream. In accordance with the invention an array of spaced differential hydraulic actuators is braced between at least one of the intake plates and the frame and is operable to deform the one intake plate and thereby change the spacings of the belts at the mouth. A controller connected to the actuators can therefore steplessly change the shape and position of the belts at the mouth.

Filed: 1998-02-06
Abstract: A segmented, encapsulated insulation assembly (20) preferably includes a blanket (42) of fibrous insulation (22) having a plurality of longitudinally spaced apart, transversely extending cuts (28) therein. The cuts (28) divide the fibrous insulation (22) into segments (26) and weaken the fibrous insulation (22) to permit the fibrous insulation (22) to be selectively separated at any of the cuts (28). The fibrous insulation (22) is encapsulated within an envelope (24) having weakened transverse tear lines (30) that divide the envelope (24) into envelope segments. The transverse tear lines (30) in the envelope (24) overlay the cuts (28) in the fibrous insulation (22) to permit the envelope (24) to be separated at the cuts (23) thereby forming a plurality of encapsulated fibrous insulation modules (26). One or more of the encapsulated fibrous insulation modules (26) can be selectively separated from the segmented, encapsulated fibrous insulation assembly (20) to form an insulation panel of desired length to insulate a cavity.  Preferably, the surfaces (36) of the fibrous insulation cuts (28) are treated with a dust suppressant to reduce or prevent dust and/or fiber release from these surfaces (36).

Title: Water purifier
Inventor: CONRAD HELMUT GERHARD
IPC: C02F1/78
Filed: 1998-11-09
Abstract: An apparatus for the purification of water contaminated by micro-organisms and chemicals by means of a three stage process is taught. The apparatus consists of a prefiltration stage, an ozonation stage, and a post filtration stage.      The contaminated water is initially drawn from a reservoir through a filter through a bed consisting of a porous media, calcium bentonite, zeolite, activated carbon and a second porous media. The filtered water is then passed into a ozonation chamber wherein gaseous ozone is introduced so as to oxidize contaminants. The reduction/oxidation condition in the ozonation chamber serve to control the cycle time. Once the water is disinfected it is passed through a second filter consisting of a porous media and activated carbon before being dispensed into a clean water carafe.

Title: Apparatus for separating particles from a fluid flow and a valve for introducing bled fluid to a mainstream fluid
Inventor: BRAITHWAITE JAMES WILSON
IPC: F16K24/06
Filed: 1997-07-03
Abstract: A bleed valve (30) for introducing bled fluid to a mainstream fluid flowing through apparatus (16) across which a pressure differential occurs, characterised in that the bleed valve (30) is adapted to open so as to bleed fluid into the mainstream fluid when the pressure differential across the apparatus (16) falls below a predetermined value. This arrangement is particularly appropriate to vacuum cleaners incorporating cyclonic dust-separating apparatus in that the bleed valve is more reliably operated in response to a reduction in airflow. This ensures efficient functioning of the cyclonic dust-separating apparatus and reduces the risk of overheating of the motor.

Title: A hermetically sealed vacuum load interrupter switch with flashover protection features
Inventor: HOEGL VITUS
IPC: H01H33/66
Filed: 1997-08-25
Abstract: The invention concerns a load interrupter switch (I) for voltages in the kV range, with a vacuum interrupter chamber (2) which is surrounded in a gap-free manner by a sleeve (4) formed from elastomer material having high dielectric strength. The sleeve (4) is in turn clamped by the two halves (11 and 12) of the housing of the load interrupter switch (1). In this way, external flashover of the high voltage between the end plates (24 and 25) of the vacuum interrupter chamber (2) is effectively prevented during switching operations without the need for liquid or gaseous media. In this way, in contrast to conventional load interrupter switches, complicated monitoring is unnecessary and the load interrupter switch is not harmful to the environment.
