Patent number: 4280562Abstract: A fire protection sprinkler head construction comprises a frame having at one end a water passage therethrough which normally is closed by a seal maintained in passage sealing position by a thermally sensitive strut which collapses in response to a predetermined increase in its temperature and enables water to flow through the passage. At the other end of the frame is a deflector against which water flowing through the passage impinges and is deflected outwardly in a spray. Encircling the deflector is an annular distributor having a plurality of circumferentially spaced apart blades which intercept water deflected outwardly by the deflector. The blades are twisted at their root ends and bent at their free ends to cause water impinging upon the blades to be divided into relatively large droplets and distributed circumferentially.Type: GrantFiled: November 14, 1979Date of Patent: July 28, 1981Assignee: Globe Fire Equipment CompanyInventor: Hermann R.

Patent number: 4071193Abstract: Flow spreading method and apparatus particularly adapted for use with a generally parabolic, slotted screening or dewatering surface, which redimensions the cross-sectional shape of a flow of material from a relatively narrow width, deep depth flow to a relatively shallow depth, wide width flow approximately equal to the width of the surface to which the flow is delivered. The apparatus includes a curved plate preferably having a substantially constant radius of curvature and a conduit which directs the material against the curved plate non-tangentially with respect to its surface to induce a smooth but rapid redirection and hence, redimensioning of the flow cross-sectional configuration. The conduit feeding the material may have at least its terminal portion constructed of a flexible material which allows the conduit outlet to be pressed against the surface of the curved plate and deformed somewhat to enhance flow spreading while still permitting the passage of relatively large objects through the conduit.Type: GrantFiled: July 19, 1976Date of Patent: January 31, 1978Assignee: The Black Clawson CompanyInventors: Arthur J.
