Patent FR-2252270-A1 (FR)
IPC: B65G47/50
Filed: 1974-11-20
Abstract: The invention is directed to a system for routing assorted items to preselected destinations. The items to be routed are deposited at any of various reception areas and automatically routed to a particular final destination depending upon the nature of the item. Each item carries a machine readable label, such as a bar coded label, which is scanned by an appropriate scanning mechanism. Information encoded onto the label is then obtained by the scanning mechanism and is injected into appropriate logic decoding circuitry where it is decoded to identify the item, its destination, or both. The decoded information is then applied to the system control logic which routes the label bearing item to the appropriate destination. Movement of items within the system is affected by conveyors or similar devices and appropriately located diverters to control transfer of the items to various conveyor loops or spurs.

Title: Pressure relief valve for safe-handling cabinet - utilises weight of disc within valve chamber to control blow-off pressure
IPC: F16K17/12
Filed: 1976-04-16
Abstract: Safe-handling cabinets which are used when dealings with dangerous substances such as radio-active materials, toxic gases or micro-organisms are normally operated at a pressure below that of the surrounding atmosphere to reduce the risk of escape of contaiminated material. But in the event of an explosion within the cabinet it is necessary to provide an outward pressure relief valve. Such a valve consists simply of a disc (12) resting on a seat (11) provided with an O-ring seal (10). As soon as the pressure within the cabinet rises by a few millibars it pushes the disc (12) upwards to the position (12a) allowing the gases to escape through the hole (6). The relief pressure is determined solely by the weight of the disc (12) and can therefore be very accurately controlled.
