Patent number: 9222221Abstract: A cleaning apparatus includes at least one cleaning nozzle that generates and directs a high-pressure liquid jet towards a point of impact on a surface, such as a conveyor belt having a drying screen. A cleaning head has a main opening that faces towards the surface, a discharge opening and a wall with at least one inlet opening defined therein. The at least one cleaning nozzle is disposed outside of the cleaning head and is oriented such that the high-pressure liquid jet passes through the at least one inlet opening before striking the surface. At least one first compressed air supplying device is disposed outside of the cleaning head and is configured to steer liquid from the at least one cleaning nozzle, after it has struck the surface, towards the main opening of the cleaning head.Type: GrantFiled: July 14, 2014Date of Patent: December 29, 2015Assignee: PAPRIMA INDUSTRIES INC.Inventor: Roman Caspar

Patent number: 4455197Abstract: A stock delivery system is provided having a rectangular sectioned distributor of substantially square section connected in stock supplying relation to a headbox having an apertured distributor place, a mixing chamber receiving stock therein connecting by way of a throttle plate to a multi-tier diffuser section comprising cylindrical tubes that diverge to a square section. A parallel flow section of predetermined length connects to a tapered nozzle section. The structural elements of the apparatus, including the support beam, a portion of the diffuser section, and the roof section are connected in liquid transfer relation to permit the passage of liquid a controlled temperature therethrough. Also, the slice is provided with liquid containment capability, and also includes a segmented extension chamber to permit substantially unrestricted later expansion or contraction of the slice under changing thermal conditions.Type: GrantFiled: December 6, 1982Date of Patent: June 19, 1984Assignee: Dominion Engineering Works LimitedInventors: Denis Croteau, Roman Caspar, Ramamurthy G.
