Patent GB-1255939-A (GB)
Title: Manufacturing apparatus
IPC: B65G47/46
Filed: 1968-12-12
Abstract: 1,255,939. Workpiece transferring. CINCINNATI MILLING MACHINE CO. 12 Dec., 1968 [15 Dec., 1967], No. 59171/68. Heading B3B. [Also in Division B8] In a manufacturing layout, workpieces on pallets are circulated on a main conveyer loop 11 that has cross conveyers 14-19 and 21 containing work stations 23-29 that may comprise one or more machine tools. At the junctions of the main loop 11 with the cross conveyers are provided turntables 31. The pallets carry addressing means that co-operate with address readers 36, 37 to ensure that a workpiece is delivered to a suitable machining station. If a cross conveyer is full with a queue of workpieces for a particular machining station the address reader 36 at the appropriate junction is overridden and instead of the turntable being rotated to send the workpiece down the cross conveyer it is retained in the main loop 11 and directed to another machining station. The conveyer comprises driven rollers and the turntables are formed by separable parts of the roller conveyer which can be raised and rotated through 90 degrees. The rollers on the turntable are driven by an engagement with the driven rollers of either the main loop 11 or a cross conveyer. The pallet addressing means comprises a block (57) (Fig. 7, not shown) extending across the conveyer width and having a row of fingers (58) that can be in a raised or lowered position. The fingers (58) include a sideways extending pin 62 which is used for automatically moving the finger into either of its positions to either set or erase an "address". The "address" is read by the readers 36, 37 which comprise a manifold extending across the conveyer and connected to an air pressure supply. The manifold includes a number of sockets which either contain blanking caps, or pilot valve (59) in a position to be actuated by a finger (58) as a pallet passes over the address reader. When the pilot valve is actuated a slight pressure rise in the manifold is sensed by a switch (73) which actuates the appropriate action. The address reader 37 in the cross conveyer verifies-that a correct workpiece is in a correct queue. When a pallet leaves a machining station an address can be set or erased by an address modifier 40 comprising fixed cams (Figs. 11-13, not shown). The machining stations are numerically controlled. The control of the manufacturing plant allows a single machine tool to perform a number of dependent operations on a workpiece, or for a series of dependent operations to be carried out sequentially on a number of machining stations, or for groups of workpieces with non-dependent operations to be operated on in any order as machining stations become available.

Title: Separating gas mixtures
IPC: B01D53/047
Filed: 1978-07-12
Abstract: A gas mixture to be separated is passed under pressure over a carbon molecular sieve which preferentially adsorbs one or more components of the mixture, gas rich in the unadsorbed component or components of the mixture being withdrawn from the adsorber, the adsorber is regenerated by reducing the pressure to release a gas enriched in the adsorbed component or components, is repressurised and the cycle repeated, the pressure build-up after regeneration being effected in at least two stages, the build-up in the first stage or stages being rapid to an intermediate pressure, and the build- up in the last stage to the final adsorption pressure being markedly slower. Such a pressure build-up pattern leads to a reduction in the amount of adsorbable component breaking through to contaminate the product during at least the beginning of the adsorption step. The invention is particularly applicable to obtaining nitrogen-enriched or oxygen-enriched fractions from air and does not require the use of special measures for the preliminary removal of CO2 and water.
