A filling/sealing apparatus used for ampules generally has a feed star wheel feeding ampules, a turntable transporting the ampules delivered from the feed star wheel, and an intermediate star wheel interposed between the feed star wheel and the turntable. Around the turntable, filling needles fill the ampules with liquid, burners seal the upper ends of the ampules, and pincers pinch the upper ends of ampules. Sensors determine whether the ampules being transported by the intermediate star wheel have the upper ends intact and damaged ampules are removed. The number of ampules that can be held by the turntable as well as the star wheel is set to integral times as many as the number of ampules that can be simultaneously filled by the filling needles.

In the microwave oven of square waveguide type or coaxial tube type, the waveguide or inner conductor of the tube type is gradually declined from the inlet toward the outlet of the oven. A top slot is provided so that containers may be moved along the slot with their bottom portions being received in the oven and the contents heat sterilized. There is laid on a bottom surface of the oven a support rail for the bottoms of the containers, and this rail is gradually thickened from the inlet toward the outlet. More preferably, two or more such microwave ovens may be serially connected and the containers may be moved therethrough to heat sterilize medical fluids within each container in a stepwise manner.

Sterilizer for sealed container utilizing microwave

To take upright articles such as ampules out from a case for storage thereof, the case having a pair of laterally opposite side plates formed with a pair of vertical slots, respectively, which are provided with pointed protrusions, defining notches into which a shutter is removably engaged and thereby held in a posture inclined forward with respect to the transporting direction. A control device is adapted to disengage the shutter from the notches and then to engage the shutter into the other notches so as to erect the shutter. A front ejector plate is inserted into the case and the shutter is removed by a chuck from the case. A pusher plate provided on the inner side of a case rear side plate pushes the ampules forward and the rear ejector is inserted into the case. Then a device for moving the front and rear ejector plates is actuated horizontally and thereby the upright articles are transported onto a conveyor. A case feeding station is provided with a feeding conveyor and a case discharging station is adapted to discharge the empty case having completed transport of the upright articles.

Method and apparatus for take out and transport of upright objects such

An improvement of a method and an apparatus for detection of an extraneous solid substance which may exist in a transparent liquid wherein a sealed transparent container filled with the transparent liquid is rotated to cause rotation of the extraneous solid substance mixed and floated in the liquid. Light is projected through the container and the intensity of the light passed through said container is measured. The invention is characterized in that an optical fiber line-circle converter has its linear end formed into two or more straight files which may be set on the same or different level lines, respectively. The present method and apparatus can detect more precisely the extraneous substance moving in an irregular motion in the transparent liquid.

Method and apparatus for detecting extraneous solid substances contained

An improved method for inspection of extraneous substances which may exist in a transparent liquid filled in a transparent container such as an ampoule which comprises rotating the container, projecting light through the liquid in the container, measuring the intensity of light beams passed through the container, and determining the extent of interception of light due to the presence of the substances. The invention is characterized by providing two rotating scan heads on an optical fiber line-circle converter and connecting two photoelectrical elements to the heads. This achieves, with the conventional speed, essentially the same effect as that obtained by doubling the rotating speed of the scan heads.

Method and apparatus for inspecting extraneous solid substances

Method and apparatus for detecting and measuring solid alien substance(s), which may adversely exist in a liquid contained in a transparent container, are provided. Light is applied to the container as it is rapidly rotated and then suddenly stopped to cause floating or suspending the solid substance(s) in the liquid. The light passed through the liquid or passed through light and also the light reflected from the solid substance(s) are separately captured and their individual intensities are measured by means of photometry. The method and apparatus may be utilized for sorting out the transparent liquid from that contaminated with solid impurity, depending upon the intensity(s) of the captured light or lights.
