Title: Adsorptive separation of olefinic hydrocarbons from paraffins involves the regeneration of molecular sieve guard bed by using an internal stream of desorbents as a flush
Inventor: SOHN STEPHEN W
IPC: C10G25/03
Filed: 2000-08-21
Abstract: Molecular sieve guard bed useful for adsorptive separation of olefinic hydrocarbons is periodically regenerated by using an internal flush stream of desorbents which is recovered and reused. Separation of a hydrocarbon from a feed stream (1) comprises periodically regenerating a molecular sieve guard bed (2) by purging (1) from (2) using a liquid phase stream (4) of a desorbent (3) and passing the effluent of (2) into a fractionation column used to separate (3) and raffinate compounds. (4) is then continued to pass through (2) and the effluent of (2) is transferred to a desorbent recovery fractionation column. Independent claims are also included for the following: (A) prevention of a poison for the molecular sieve adsorbent used in a continuous adsorptive separation process from entering the process comprises: a)contacting (1) with (2) which adsorbs the poison present in (1); (b) periodically purging (2) by passing (4) containing (3) through (2) and passing the effluent of (2) into a raffinate column to separate raffinate compounds and (3); and (c) regenerating (2) by passing an additional quantity of (4) through (2) and passing the effluent of (2) into a recovery fractionation column to recover (3) from the effluent of (2); and (B) a simulated moving bed process for the separation of linear olefinic hydrocarbon (5) from (1) comprises contacting (1) with (2) to cause the selective retention of (5) on the molecular sieve and the resultant formation of the raffinate stream is passed into the raffinating column. The retained (5) is recovered by periodically regenerating (2) with (4) containing (3) and initially passing the effluents of (2) into a raffinate column and then switching the flow of the effluents to the desorbent recovery column.

Title: Method and device for instantaneous determination of orientation, based on satellite positioning signals
Inventor: GOUNON RENE
IPC: G01S19/54
Filed: 2001-04-12
Abstract: The invention concerns orientation measuring of a mobile object in space, for example a ship's heading using receivers of satellite positioning radio signals. To obtain very rapidly an orientation measurement, the method consists in using two receiving antennae located in two points A and B whereof the distance D is well known, and in proceeding in the following manner: performing n successive calculations of position of the point A relative to the point B (for example a dozen successive calculations if the distance D is 40 centimetres) from a single set of 2p pseudo-distances measured between each antenna and p satellites. The n calculations correspond to n initial estimated positions (Ae1 to Aen) used as initial hypothesis for calculation. The n estimated positions are located on a circle with centre B and radius D. The calculated positions (Ac1 to Acn) are located at distances d1 to dn from point B; selecting a position Ack representing the true position of point A by verifying that said position is on the circle with centre B and radius D within a few millimetres; optionally improving the selection by verifying the measurement coherence (if there are more than four satellites involved).

Title: Method for lubricating and cooling journal bearing used in e.g. gas turbine uses cold lubricant fed under pressure downstream from bearing surface to remove hot lubricant adhering to shaft
Inventor: WEISSBACHER GEORG
IPC: F16C33/10
Filed: 2001-06-21
Abstract: The method for lubricating and cooling a journal bearing uses a compression zone (20) and an expansion zone (22) which are upstream from the bearing surface. Lubricant flows through the compression zone so that it is fed in a controlled way and forms a wedge between the bearing surface (26) and shaft mounted in it.
