A pneumatic transport system for histological samples includes a transport tube within which a carrier containing samples is transported. A station for loading/unloading the samples into/from the carrier is arranged at one tube end. When the carrier is arriving at the station, a blower of the system is deactivated and the carrier is braked, allowing stopping within the station against a stop member. Thereafter a motor imparts, via the stop member, rotation to said carrier until a carrier door is at an angular position substantially corresponding to an angular position of a station door. Thereafter, the carrier is stopped and the doors are opened by an actuator, this enabling activation of an operating cycle of loading/unloading of the samples. Upon completion, the doors are closed, a carrier locking device is deactivated and the blower is activated, allowing departure of the carrier from the station and its transport within the tube.

The invention is for the purpose of launching and feeding capsules in a hydraulic pipeline based on the principle of a hydraulic jet. The jet nozzle in the body of the launcher creates a low pressure zone in the launcher in which capsules can be fed from a chute or a hopper at atmospheric pressure through a vertical indexing rotor without backflow of water into the hopper, chute or conveyor. The vertical indexing rotor is operated by a Geneva wheel system connected to a geared motor, or a servomotor controlled by a computer. The water pressure for the pipeline is provided by an external pump. The capsules are supplied by a dry conveyor, a hopper and a chute at the top of the launcher.

The present invention includes a configuration to move a transport body 500 in conjunction with movement of a moving body 200 due to repulsion applied between respective magnetic materials 213 and 523 when the moving body and the transport body are in a close location relation, and, when the moving body separates from a range of the close location relation due to halfway stop of the transport body, the transport body is moved in the opposite direction to stop at a predetermined end portion stop position, subsequently only the moving body is caused to travel in a direction further away from the transport body, and the moving body is returned into the range of the close location relation by causing the moving body to travel toward the transport body at a speed resistible against the repelling force.

A non-contact conveyance device includes a conveyance head in which a flat facing surface opposing a conveyed object is formed, a gas supply port connected to a supply source of compressed air is provided in the conveyance head, each of ejection ports of a plurality of ejection paths that communicate with the supply port and are formed in the conveyance head is provided at a position separated by an opening distance from a holding center point of the facing surface, an inclination angle of the ejection path with respect to the facing surface is set to an acute angle, and the compressed gas ejected from each of the ejection ports flows along the facing surface and holds the conveyed object without causing the convey object to contact with the facing surface.

A pressure and vacuum generating module for a carrier transport system includes a combined blower, air chamber and rotating valve module which alternately couples a pressure chamber and a vacuum chamber to the carrier transport system, creating high or low pressure regions which move a transport carrier. The valve repositions a baffle which blocks one or the other of the chambers, or both chambers, the latter for breaking and landing of the carrier. With a chassis that includes the blower motor, air chamber and valve, the module is adapted for new construction as well as for retrofitting and replacing older legacy blower modules.
