The pump section is a positive displacement pump.

Abstract: An apparatus for inspecting plate-like bodies to inspect a side surface of a plate-like body with sheeted coating materials on a top side and bottom side of the plate-like body, is provided. The apparatus includes at least one light emitting unit configured to irradiate the side surface of the plate-like body with light. The apparatus includes at least one light receiving unit configured to receive light reflected with respect to the side surface of the plate-like body. The apparatus includes a conveying unit configured to move at least one among the light emitting unit and the plate-like body and to vary a position of the light on the side surface of the plate-like body, emitted by the light emitting unit.

Abstract: A pretreatment mixing and stirring device, arranged at a stage prior to a slurry formation mixing and stirring device which forms a gypsum slurry by kneading a calcined gypsum and water, and performing a pretreatment by mixing a calcined gypsum with one or more kinds of additives selected from liquids and powders, comprising: a cylindrical housing having a top plate, a bottom plate arranged to oppose to the top plate, a side plate arranged between the top plate and the bottom plate, and a mixing and stirring region where the calcined gypsum and the additive are mixed and stirred in an interior surrounded by the top plate, the bottom plate, and the side plate; a disk-shaped rotating plate arranged inside the housing; a rotating drive shaft, penetrating the top plate or the bottom plate of the housing, and coupled to the rotating plate; a calcined gypsum supply port, arranged in the top plate, and configured to supply the calcined gypsum to the mixing and stirring region; and an additive supply port, arrange

Abstract: Labor saving and automatization of cleaning work of a conveyance face for articles or materials are intended to reliably and quickly execute the cleaning work. A cleaning apparatus has a cleaning implement (10) located on the upper side of a conveyance element (R). The cleaning implement includes a cleaning face (11) to be in contact with a conveyance face (S). The cleaning apparatus also has a traction device (6,7) which applies a tractive force (T) to the cleaning implement, in a direction (E) opposite to a conveyance direction (D) of a conveyance passage. The cleaning implement has a weight (P) for keeping the cleaning face in contact with the conveyance element in operation of the conveyor device, and cleans the conveyance face by means of contact and separation of the cleaning face and the conveyance face, and relative displacement therebetween (V1, V2, V3).

Abstract: The present invention provides a mixer and a mixing method which enable stable supply of slurry at a high flow rate with foam being uniformly mixed therein, and which enable reduction in consumption of foam to be fed to the slurry. The mixer (10) has a housing (20), a rotary disc (32), a slurry outlet port (45), a slurry delivery conduit (46) and a hollow connector section (47). A foam feeding port (41) is disposed in a predetermined position of an annular wall or the hollow connector section. The foam feeding port feeds the foam to the slurry, immediately before the slurry enters the slurry outlet port, or feeds the foam to the slurry in the hollow connector section. The slurry and the foam mix with each other at the slurry outlet port or on its downstream side. The foam is not substantially subjected to agitation impact of the mixer and a quantity of loss of the foam is reduced.

Abstract: A mixer 10 comprises a disc 32 having peripheral edge 35, which is formed in a circular profile concentric with inner circumferential surface 25 of annular outer wall 23; lower pins 50 provided with rear bulged portions 73 extend backward of the rotational direction R; and upper pins 60 provided with front bulged portion 72′ which extends forward of the rotational direction. A disc without a toothed formation on its peripheral edge zone can prevent the slurry from depositing on the outer periphery of the disc. Front and rear bulged portions 72′, 73 occupy a rearward area of the lower pin and a forward area of the upper pin so as not to provide retentive regions for the slurry, which might otherwise have caused a vortex or turbulent flow of the slurry. Accordingly, the deposition of slurry on the lower and upper pins can be prevented from occurring.
