Abstract: A fluidized bed separator (1) includes a feed section (4) between an upper separation chamber (19) and a main separation chamber (6). The feed section (4) has one or more feed pipes (11) extending horizontally and transversely with respect to a body wall (10) of the fluidized bed separator (1). The one or more feed pipes (11) are positioned completely and entirely underneath the inclined plates (17). An external oversize protection apparatus (3) which is separate from and external to the body wall (10) may be operatively coupled to the one or more feed pipes (11). One or more lamella cartridges (49) may be provided within channels (18) of the upper separation chamber (19), and one or more breakaway plates (54, 55) may be inserted within channels (18) to prevent sanding and facilitate insertion and extraction of the lamella cartridges (49).

Abstract: A computing platform is configured to (i) receive data objects related to a construction project, (ii) add the data objects to a construction knowledge graph as nodes that are connected to other nodes representing other data objects, (iii) determine, via a machine-learning model trained using historic construction project data, a first risk score for a first data object, (iv) determine, via the machine-learning model, a second risk score for a second data object, where the second risk score is based on (a) the first risk score and (b) a degree of separation between the first data object and the second data object in the construction knowledge graph, (v) based on the second risk score, automatically generate a suggested action to be taken with respect to the first data object, and (vi) cause an indication of the suggested action to be displayed at a client station of a user associated with the construction project.

Abstract: In some embodiments, a pipe boot flange may include one or more fitting portions. The pipe boot flange may include one diaphragm gate. In some embodiments, a method may include injecting a flow of a resin through a runner and into a diaphragm gate of a mold cavity for a pipe boot flange. The method may include directing the resin through the mold cavity. The method may include forming the pipe boot flange. The method may include removing the formed pipe boot flange from the mold cavity.

Abstract: A drywall trim for protecting drywall can include a metal body having a seam with a longitudinal axis. The metal body can include wings or planar portions that extend from the seam in transverse directions relative to the longitudinal axis. The planar portions can be formed at an angle relative to each other. At least one of the planar portions can have an outer edge that is not parallel to the seam. Paper can be bonded to the metal body.

Abstract: A scroll assembly (1) for a centrifuge (100) may be characterised in that it includes at least one lamellae pack assembly (11) proximate the first end (9) of the scroll (2). The lamellae pack assembly (11) may have a plurality of lamella plates (11d) and be positioned upstream of a weir (31) or an effluent exit port (4) that permits a liquid fraction (33) of said infeed slurry to discharge from the centrifuge (100). The lamella plates (11d) are preferably configured and arranged to bias fine solids (35) entrained within the liquid fraction (33) radially-outwardly or at least hinder their radially-inwardly migration as the liquid fraction (33) passes through the lamella plates (11d) and before the liquid fraction passes the weir (31) or effluent exit port (4), in order to produce discharged clarified liquids (36) which are substantially-free of the fine solids (35).

Abstract: A high-flow ember shield building ventilator for use with roof or attic exhaust systems has a substantially rectangular outer frame portion with four side walls and a bottom wall, and a folded screen insert inserted into an opening of the frame portion. A cylindrical frame having a screen installed thereon is mounted onto the rectangular frame portion over the folded metal insert. A high-flow ember shield alternatively has a cylindrical frame with a screen insert formed by concentric rings of mesh material.

Abstract: A high-flow ember shield building ventilator with a substantially trapezoidal outer frame portion with a long side, a short side, a substantially vertical front side and opposing angled sides; and a folded metal insert. The long side has a first long side end and a second long side end, the short side has a first short side end and a second short side end, the substantially vertical front side has a first substantially vertical front side end and a second substantially vertical front side end, the angled side has a first angled side end and a second angled side end and the folded metal insert is between the first angled side end and the second angled side end.

Abstract: A cornerbead for drywall construction having an elongated strip with a longitudinal nose bent at a substantially right angle and having a left side and a right side extending outwardly from the longitudinal arcuate nose; at least one raised portion extending the length of the left side; and at least one raised portion extending the length of the right side.

Abstract: A cornerbead for drywall construction according to one embodiment having an elongated strip bent at a substantially right angle to form an upper portion having an upper edge and a lower portion having a lower edge; and at least two triangular cut out projections along the upper edge and at least two triangular cut out projections along the lower edge.

Abstract: A drywall trim for protecting drywall can include a metal body having a seam with a longitudinal axis. The metal body can include wings or planar portions that extend from the seam in transverse directions relative to the longitudinal axis. The planar portions can be formed at an angle relative to each other. At least one of the planar portions can have an outer edge that is not parallel to the seam. Paper can be bonded to the metal body.

Abstract: A roof system can include a roof deck that supports roof tiles. The roof system can further include a bird stop to support a first course of the roof tiles adjacent an eave of the roof deck. The bird stop can be solid and have apertures. Each aperture can include a through hole and a deformed portion behind a respective through hole. Each through hole can have a length and a width. At least one of the length and width can have a maximum dimension of not greater than ? inch.
