Filed: 1987-04-02
Granted: 1989-11-02
Abstract: 1. A process for the production of nitrogen through the low temperature rectification of air, wherein the air is compressed and divided into two sub-streams, of which the first is cooled and supplied to a singe-step rectification stage whilst the second is subjected to secondary compression, cooled, expanded and likewise supplied to the rectification stage, and wherein the nitrogen is obtained from an upper section of the rectification stage, characterised in that before it is supplied to the rectification stage (7) the first sub-stream (5) is brought into heat exchange with sump fluid (11) from the rectification stage (7), that the expansion of the second sub-stream (4) is carried out with the production of work and that at least a part of the work produced by the expansion is used for the secondary compression of the second sub-stream (4).

Granted: 1991-11-13
Abstract: An electromagnetic identification system of the kind comprising a transmitter for generating an electromagnetic interrogation field in a detection zone, at least one passive responder (4) capable of disturbing said interrogation field, and detection means for detecting a disturbance of the interrogation field caused by a responder. The responders comprise a single receiver circuit (5) which in response to an interrogation field, via rectifier means (6), can supply energy to active digital encoding means (7) comprising a binary-code defining means, and the encoding means is arranged, in operation, through a switch means (9), to vary the electrical characteristics of the receiver circuit in the rhythm of the binary code to generate a code signal that is detectable by the detection means. The encoding means is arranged to control the switch member (9) during pre-determined periods of time for varying the electrical characteristics of the receiver circuit (5). The pre-determined periods of time alternate with intervals during which the electrical characteristics of the receiver circuit are not affected. According to the present invention, the encoding means comprise a decoding section which in response to a modulation of the interrogation field can, at least in part, change the binary code defined by the code-defining means, and there is provided a transmitter comprising a programme (21) for providing such modulation. The transmitter is arranged, in operation, to generate a modulated interrogation field during said predetermined intervals.

IPC: C07C29/86
Filed: 1987-01-13
Granted: 1991-03-13
Abstract: A method and apparatus for removing water from a liquid mixture of water and ethanol contacts it with liquid carbon dioxide so that the ethanol is preferentially transferred into solution, dries the solution using an adsorbent, and then recovers dry ethanol by distilling off the carbon dioxide. This process is particularly energy efficient especially when it includes a fermentation process to generate the ethanol and uses the carbon dioxide generated during the fermentation as the source of liquid carbon dioxide. In this case the method and apparatus provide an additional product of dry carbon dioxide.

Granted: 1993-06-16
Abstract: The invention provides a method of communicating data between a pair of transceivers in a full-duplex manner using a send-and-wait data handling protocol. The transceivers are connected by a pair of communication paths and each transceiver is adapted to simultaneously transmit data on one communication path and receive data on the other. Each transceiver generates primary and secondary messages and these are multiplexed by injecting the secondary messages into the primary message stream in such a way that the secondary messages are readily differentiated from the primary messages at the receiving transceiver.

Title: Method and apparatus for processing a hydrocarbon-air mixture
IPC: B01D53/22
Filed: 1987-11-20
Granted: 1991-10-02
Abstract: Known processes for the treatment of hydrocarbon/air mixtures result in an unsatisfactory degree of purity of the waste air. Treatment of the said mixture by means of a so-called membrane module is advantageous. The treatment result is, however, unsatisfactory and is therefore to be improved by subsequently oxidising the mixture which is low in hydrocarbons when it issues from the membrane module, to produce carbon dioxide and water as well as residual air. <IMAGE>

The pellets are then fed to the pyrolysis zone of a rotary kiln wherein they are heated by hot gas from an oxidation zone of the kiln to drive off most of the volatile gases. Remaining volatile gases and the fixed carbon in the waste are oxidized in the oxidation zone, and the silicates in the clay are vitrified in a vitrification zone of the kiln to produce aggregates which are crushed and screened. Volatile gases given off from the pyrolysis zone are mixed with exhaust gases from the dryer to feed the burner for the vitrification zone and to supply oxygen to the oxidation zone.

Abstract: A method of estimating motion in a picture sequence in which each picture is divided into blocks defined by two coordinates (m,n), respectively, indicating the row of the picture line in which the block is present and the row of the block on this m-th line. This method provides for: defining three groups for the blocks classified in fixed blocks, moving blocks and exposed blocks, in which groups the blocks are classified with a delay in accordance with the scanning of the picture by examining a given number of possible group sequences; constructing a classification tree whose 3L branches at each successive level are equal in number to those of the possible groups; associating to each branch a first parameter referred to as displacement vector representative of the possible displacement of the block with respect to the picture or to the preceding line and a second parameter referred to as cumulated distortion representative of the cumulative sum of the classification errors of the preceding blocks; in accordance with this procedure relating to L blocks, taking a decision of the majority type concerning the effective group and concerning the displacement vector of the block situated L blocks earlier with respect to the current block.

Title: Bulk containers & manhole covers therefor
IPC: B65D90/34
Filed: 1988-07-18
Granted: 1993-07-28
Abstract: A pressure material container (10) in which a manhole cover (15) has a relief valve. The relief valve includes a resilient spacer ring (61) disposed between a valve seat (55) of the relief valve and a valve plate (60). A spring (50) urges the valve plate (60) of the relief valve toward the valve seat. When the fluid pressure in the container (10) exceeds a predetermined magnitude, the valve plate (60) is lifted away from the valve seat against the urgency of the spring (50) to vent the fluid in the container (10) to atmosphere. Vacuum relief apertures (75, 75 min ) are formed in a backing plate (66) of the relief valve. The vacuum relief apertures communicate with the fluid in the container (10) and atmosphere. A disc (70) closes the vacuum relief apertures until displaced when the fluid pressure of the fluid within the container (10) is less than atmospheric pressure to provide a path for air under atmospheric pressure to flow into the container (10) through the vacuum relief apertures (75, 75 min )
