	Removable glide rings for pneumatic tube carriers - Patent 5901966
		One area of commerce which currently uses the pneumatic tube and the transporting of material via the pneumatic tube on a fairly regular basis is the hospital or biomedical research/manufacturing industry.
		Pneumatic carriers for use in such delivery systems come in a wide range of sizes and shapes to accommodate the physical articles to be transported in the system.
		Although the carrier tube walls are often made of steel, and the carriers 10 are often made of plastic, it is generally desirable to have only smooth, continuous surfaces contacting the interior of the pneumatic tube walls.

		Short tubes, known as house tubes are in use in a great number of offices; such tubes, which are worked either by handpumps (when the tubes are very short and the traffic light) or by power, are usually 1.75 in.
		On some of the long tubes a carrier, when it passes the midway point in the tube, strikes a trigger and sends back an electrical signal indicating its passage; on the receipt of this signal a second carrier may be despatched.
		The trains of canisters arrive via the tube at the bottom, and appear in the vertical column P. The tank B is initially full of with air, which is compressed by the introduction of water from the Paris mains via the upper pipe b.
