Abstract: A disc filter assembly includes a number of filter discs mounted in a vat by a horizontal shaft with an inter-disc volume between the discs. A feed mechanism is provided that makes it possible to feed the pulp suspension onto the surface of the liquid, directed toward the most concentrated pulp in the vat, in such a manner that the feed is insensitive to fluctuations of the suspension surface level in the vat. This is accomplished by feeding the suspension into the vat interior directly into each of the inter-disc volumes, as by using a chute (which may have the approximate configuration of a hollow triangular parallelepiped) for each volume. A header for supplying pulp suspension to the chutes may be mounted on or spaced from the sidewall of the vat, or above the vat.

Title: Improved steam desuperheater
Inventor: FEISS ROY L
IPC: F22G5/12
Filed: 1993-12-13
Abstract: A desuperheater (10) is disclosed which employs an acceler-ation orifice (34) within a steam conduit (18) to increase the veloc-ity of steam flowing therethrough, creating a region of low pressure steam. A nozzle (50) having an enclosed elliptical discharge ori-fice (60) sprays small droplets of cooling water in a semi-elliptical hollow cone pattern directly into the region of low pressure steam flow.

Title: Apparatus and method to prevent flailing damage to a strand wound on a spool
Inventor: DARSEY RALPH JOEL
IPC: B65H57/00
Filed: 1996-01-05
Abstract: This invention is an apparatus and method for reducing or preventing damage to a strand wound at relatively high speed on a machine-rotated spool, caused byflailing of a loose end of the strand.  The apparatus includes capture brushes arranged at intervals in proximity to the machine.  The capture brushes are aligned to beapproximately perpendicular to the loose end of the strand when the loose end of the strand rotates with the spool into contact with the brushes.  At respective ends, the brushes have respective tips with a taper that tends to guide or deflect the loose end of the strand to a slot defined by two adjacent brushes.  The brushes have bristlesextending from a bristle-mounting member, which capture the loose end of the strand. The bristles can be treated with a friction enhancing substance to improve the ability of the brushes to capture and entrap the loose end of the strand.  Preferably, the bristles are angled with respect to the bristle-mounting member in a direction away from a respective tapered tip.  As so angled, the bristles allow the loose end of the strand to pass relatively easily between adjacent brushes in one direction, but capture and entrap the loose end of the strand and prevent it from recoiling in the opposite direction out of contact with the bristles.  A loose end of the strand is thus captured before it can damage the strand wound on the spool.  After capture, as the spool rotates, the loose end of the strand is drawn through the bristles of the adjacent brushes in a direction approximately perpendicular to the bristle-mounting members.  Thus, flailing or whipping of the loose end of the strand against the strand wound on the spool isprevented.
