Abstract: The present invention is directed to a pipe identifying apparatus in use for a pneumatic force type device for transporting powdered materials, a dryer and the like. The pipe identifying apparatus comprises a plurality of magnetic rings and non-magnetic rings which magnetic rings and non-magnetic rings form specific identifying codes for each of a plurality of pipes and proximity switches provided on the side of receiving part of the pipe and associating with the magnetic rings to form a magnetic circuit, so that the magnetic circuit is closed to generate electric signals between each proximity switches and each of the plurality of magnetic rings and non-magnetic rings, thereby identifying specific connected pipes by means of the generated electric signals.

Abstract: The present invention is concerned with a collector, used for supplying powdered or granular materials such as various kinds of raw materials for plastic to a plastic molding machine, which can automatically switch multi-materials. The collector comprises a separation box connected to a main body of the collector, a rotary valve being pressed to a vacant chamber of the separation box for being mounted thereto such that the rotary valve may be rotatable to and fro, and a separator provided on a bottom of the rotary valve and is constructed such that a rotational displacement of the rotary valve permits a passage for guiding materials to communicate selectively with an inlet of materials and a gas introducing port to execute replacement of materials and compressed gas can be supplied from the gas introducing port, when a coincidence between the gas introducing port and the passage for guiding materials is made.

Abstract: A system for mounting a hub to an optical disk comprises a turntable arranged on an X-Y stage, a loading rod arranged above the turntable and extending vertically, a chuck provided at a lower end of the loading rod, for holding the hub with the axis of the hub aligned with a reference line as the axis of the loading rod, and a pair of displacement sensors for detecting a deviation of the axis of the turntable from the reference line, whereby the X-Y stage is driven in accordance with the signal from the displacement sensors, to position the turntable such that the axis of the turntable is aligned with the reference line. Thereafter, the optical disk is placed on the turntable with the axis of the optical disk aligned with the axis of the turntable, and the hub is placed on the optical disk through an ultraviolet-curing adhesive, by using the loading rod, with the axis of the hub aligned with the axis of the turntable.

Abstract: An arrangement of pneumatic-transporting a powdered or granular maerials such that they do not lodge, using the transport pipe smaller diameter having the bore 2-6 times as long as maximum length of the particle of the powdered or granular materials to be transported, while the powdered or granular materials are caused to float at the inlet of the transport pipe or in the vicinity of the inlet thereof by the powdered or granular materials floating apparatus with help of the collector provided on the transporting destination at the outlet of the transport pipe.

Abstract: A dust collector adapted for use in a hopper dryer including an outer rigid member and an inner filter member which is provided concentrically with the outer rigid member, the outer rigid member having a number of pores punched in its peripheral surface and the inner filter member having a filter element corrugated axially of the filter member.

Abstract: An apparatus for mixing and dispersing powdered or granular materials into a liquid solvent with a pneumatic transport means including a supply hooper, a pressure vessel which receives granular materials from the hopper for pressurization, a granular material transport pipe attached at one end to the discharge portion of the pressure vessel, a pneumatic force source for feeding the granular materials under pressure through the granular material transport pipe to a mixing tank accommodating the liquid solvent therein. The granular material transport pipe is connected to the mixing tank in an upward or lateral direction at the level below the surface of the liquid solvent contained in the mixing tank. With this structure the granular material is kept from scattering towards the upper portion of the mixing tank, making the operation more sanitary.

Abstract: Transporter and method for directly transporting powdered materials or the like by a pressurized gas from the delivery container to a hopper connected to packaging or pilling machines through a pipe arrangement connected to the container at its one end and the hopper at its other end. The container is combined with a conical part to form an airtight system by a connecting device, inverted by a turning mechanism and then connected to the pipe arrangement through the conical part, and thereafter, the powdered materials in the container are transported to the hopper by the pressurized gas fed from pressurized gas feed-pipes connected to specified locations of the sigmoid pipe.
