摘要： Shower apparatus has a pressure fluid conduit with spray nozzles having body portions immersed in the fluid and internal valve members movable between a spray position restricting the capacity of the spray outlet and a purge position in which such capacity is enlarged, the nozzle body portions having inlet and outlet ports differently located in the fluid flow path in the manifold so that the valve members are shifted between spray and purge positions by pressure differential changes between the pots produced by opening and closing a conduit outlet valve to vary the fluid flow rate.

摘要： A slotted screen for slurry is produced by Electrical Discharge Machining the slots in groups in a curved screen plate of metal at least one-eighth inch thick immersed in a dielectric liquid. The slots are formed by two sets of electrodes successively applied, the first set producing indentations extending partially through the plate, the second set forming narrower slots extending from the base of the indentations through the remaining thickness of metal.

摘要： Screening apparatus capable of making a sharp separation based on size of solids in fluid pulp has a screen cleaning rotary drum wall disposed adjacent to a screen plate. According to one aspect of the invention the rotor and screen plate form an accepts zone, the drum wall having sloped pulse-generating surface portions that sweep fully across the effective apertures of the screen plate, producing fluid pulses that act to dislodge over-size solids from the apertures, the accepts fluid flowing with an axial component along the rotor wall as it flows toward the removal outlet. Preferred embodiments include an inward flow machine, with rotor within a cylindrical screen plate; rotor cross-sections identical in planes through all apertures in the screen plate; curved rotor surface portions, e.g., elongated cylindrical sections or smooth lobes; flat rotor surface portions sloped relative to the rotor circular path; narrow axially extending screen apertures; rotor which aids in driving accepts fluid into the accepts outlet; inlet spreading of stock over the full length of screen toward rejects outlets at opposite ends and other important details. According to another aspect of the invention mutual extensions of screen plate and rotor surface combinations beyond the apertured region of the plate preserve the full intensity of positive or negative pulses in the end rows of screen plate apertures.

摘要： A high horsepower motor and gear system is provided in which the motor has a hollow drive shaft and the first stage drive gear has a long shaft extending through the hollow drive shaft and fixedly attached thereto at its far end, the latter shaft being sufficiently resilient to absorb positional errors which would otherwise result in high dynamic load exerted between the first gear pair. The system permits reduction in gear size which would otherwise be required, close coupling and ease of alignment between the two mentioned shafts and between the first stage drive and driven gears, being particularly useful as the drive for an aerator impeller.

摘要： Apparatus in which a multiplicity of spaced fluid jets can be initiated extremely rapidly when required, e.g. to remove a broken paper web from the return run of the wire of a paper making machine, comprises a fluid supply pipe connected to a multiplicity of nozzles each normally sealed by sealing means which are connected to a pressurized fluid-containing manifold, means being provided to release the pressure in the manifold rapidly when desired thereby unsealing the nozzles and causing fluid jets to be established. A pipe 12 carries a multiplicity of spaced nozzles 11 and is divided by an internal partition 14 into a pressure fluid supply passage 20 and a pressurized manifold 28. Pressure in the two parts of pipe 12 may be maintained independently or small holes 41 may be provided allowing fluid to leak from passage 20 into the manifold 28. The latter is connected to a solenoid-operated quick-acting valve adapted to release the pressure from the manifold 28 when desired, the release of pressure causing valve members 48, Fig. 2 (not shown), associated with each nozzle 11 to move to a nozzle-open position (shown dotted). In this position fluid from the passage 20 flows via holes 44 to orifices 56 and strikes jet deflector plates 58 thus establishing a series of spaced fluid jets. Photo-electric sensing means are employed to detect the breakage of the paper web in a paper making machine, Figs. 3 and 5 (not shown), and through a suitable electric relay control the opening of the solenoid-operated pressure release valve and thereby control the initiation of the jets of fluid. In a modified form of the spray nozzle, Fig. 6 (not shown), a flexible diaphragm is used to make a seal between the valve member of each nozzle and the walls of the tubular member in which the valve member is arranged to move.
