Abstract: Provided is a magnetic filtration apparatus with a simple structure for permitting easy and effective discharge of magnetic substances from the inside of a flow passage to its outside, the magnetic substances being captured by attraction from a liquid to be treated by magnetic separation. The magnetic filtration apparatus includes a treatment container 12 having an inlet 26 and outlet 28 of the liquid, and a discharge port 36 of the separated magnetic substances. A magnetic apparatus 20 attached around the treatment container 12 attracts the separated magnetic substances to an inner wall of the treatment container 12, while cancellation of the effect of the magnetic field generated by the magnetic apparatus 20 allows the attracted magnetic apparatus to flow into a detachable collecting container 14 positioned below the treatment container 12, due to the gravity, through a communication passage 15.

Abstract: An apparatus and a method for producing a casting mold are provided, according to which the casting mold having a complex shape can be obtained with stable quality. The apparatus comprises a mold having a cavity therein, a steam supply unit, a steam supply passage connected to the cavity, steam discharge passages, flow regulators disposed in the steam discharge passages to regulate an amount of the steam discharged from the cavity, and a control unit for controlling the flow regulators. After a resin-coated sand prepared by coating a refractory aggregate with a binder resin is injected into the cavity of the heated mold, superheated steam is supplied into the cavity. At this time, the control unit controls the flow regulators such that the cavity is uniformly filled with the superheated steam.

Abstract: To provide a casting mold manufacturing apparatus using steam heating. The apparatus includes a forming die having a cavity, a resin-coated sand supply section for supplying a resin-coated sand into the cavity, a steam supply section for supplying steam into the cavity, and a steam discharge section for discharging the steam from the cavity. At least a portion of the forming die is composed of a porous material having pores with an average diameter smaller than an average particle diameter of the resin-coated sand. At least a portion of the steam is supplied into the cavity through the porous material. Since it is possible to uniformly supply the steam into the cavity, a homogeneous casting mold can be manufactured.

Abstract: An apparatus including a tube which is elastically deformable and which is connected to a compressed-air passage to introduce a compressed air therefrom, a pressure lowering device which is provided at a position corresponding to an intermediate portion of the tube, and which externally presses, and thereby elastically deforms, the intermediate portion of the tube to decrease a cross-sectional area of the intermediate portion, and thereby decrease an amount of the compressed air that flows through a downstream-side portion of the tube that is located on a downstream side of the intermediate portion in a flow direction in which the compressed air flows in the tube, so that a pressure of the compressed air in the downstream-side portion is lower than a pressure of the compressed air in an upstream-side portion of the tube, the tube having an air-leak opening which is provided in the downstream-side portion thereof and which allows a portion of the compressed air in the downstream-side portion to leak into the a

Abstract: A filter device including a first filter having a first packing accommodated in a first sleeve thereof, and a second filter having a second packing accommodated in a second sleeve thereof, each one of the first and second packings cooperating with two retainer plates and a core bar to constitute a corresponding one of first and second filter elements, the two retainer plates being disposed on axially opposite ends of the corresponding one of the first and second packings, the core bar axially extending to pass through a center of the corresponding one of the first and second packings such that the two retainer plates engage the core bar at respective opposite ends of the core bar, the core bar being provided with a pull tab at one of the opposite ends of the core bar, so that the first and second packings are introduced and removed into and from the first and second sleeves, respectively.

Abstract: An in-line filter device including a partition member, and a lower housing and an upper housing which are held in a fluid communication with each other through at least one intermediate passage formed through the partition member. The lower housing has a radially inner and a radially outer filter having respective packings, for separating vapor and/or liquid particles in compressed air, and accommodates a draining device for discharging the trapped vapor and/or liquid particles. The upper housing has a mist filter of an annular porous structure for further separation of the remaining vapor and/or liquid particles in the compressed air, and an air collector disposed inside the mist filter, for delivering the filtered air.

Abstract: In-line filter device including a first and a second filter disposed parallel with each other on a trap structure such that the filters communicate with a trap chamber defined in the trap structure, so that water and/or oil vapor contained in compressed air flowing through the first filter are coalesced into droplets, which are captured in the trap chamber, while any remaining liquid particles in the air are vaporized during passage through the second filter. The device has a reduced-pressure sump in the bottom portion of the trap structure, and inlet holes through which the captured liquid flows from the trap chamber into the sump such that an upper open end of the tube is positioned in a flow path of the air between the trap chamber and the second filter, for sucking the atmosphere in the sump toward the second filter. A draining device is provided in the bottom portion of the sump, for discharging the liquid out of the sump.
