Title: Compatibilizing agent based on polyolefin with polyamide grafts and mixtures comprising same
Inventor: HU GUO-HUA
IPC: C08G69/14
Filed: 2001-07-27
Abstract: The invention concerns a compatibilizing agent consisting of a basic polyolefin chain and polyamide grafts wherein: the grafts are bound to the basic chain by the radicals of a difunctional monomer (A) having a first function acting as activator in the polymerisation of lactams and a second unsaturated function, or capable of reacting with a reactive site of the basic polyolefin chain; the radicals of the unsaturated monomer (A) are fixed on the basic chain by grafting from its double bond or by reaction of its second function with a reactive site of the basic polyolefin chain. The invention also concerns a method for preparing said compatibilizing agents which consists, after preparing the basic chain containing the monomer having an activating function, in adding the lactam precursor of the grafts, a catalyst and heating to obtain anionic polymerisation of the lactam which develops from the activating function; then in optionally separating the compatibilizing agent and the polyamide which has been formed outside the grafts.

Title: Hydraulic fluid tank, in particular for braking circuit
Inventor: FOURCADE JEAN
IPC: B60T17/22
Filed: 2002-04-23
Abstract: The closure of the breather vent (6) of a hydraulic fluid tank (1) is responsible for the faulty supply in hydraulic fluid (3) of the brake circuit (9), causing the braking to take longer and longer. In order to avoid that, the invention provides for the detection of the closure of the breather vent (6) by means of a depression detector (17) inside the tank (1). This is obtained by using a drive unit (19) suspended to a flexible and sealed bellows (20) separating two sections representing, one atmospheric pressure (18) and the other the pressure (5) inside the tank (1). When a depression occurs in said reservoir following the closure of the breather vent (6), the drive unit (9) is urged into contact with a sensor (23) located in the same space as a level detector (26). A common signalling system with the level detector (26) then warns the driver.

Abstract: The heat exchanger is purged with an inert gas to eliminate the hydrocarbons, preheated and then it undergoes at least one controlled oxidation at 400-500 degreesC for at least 4 hours using an oxidizing fluid, which is preferably an inert gas with a small proportion of oxygen. The fluids entering or leaving the exchanger stay below 520 degreesC throughout, and the hot inlet to the exchanger stays below 120 degreesC  The heat exchanger operates with a maximum service temperature less than 540 degreesC. The fluids entering or leaving the exchanger stay below 500 degreesC throughout, and the hot inlet to the exchanger stays below 100 degreesC. The temperature of at least one of the fluids entering the exchanger, or the proportion of oxygen in the oxidizing fluid is reduced if during the oxidation the temperature of one of the fluids entering or leaving the exchanger reaches or passes a limit temperature of 490 degreesC, or the hot inlet to the exchanger reaches or passes 90 degreesC. The proportion of oxygen in the oxidizing fluid is less than or equal to 2.5%, preferably 2% by mole, or is such that the temperature differential in total adiabatic combustion is less than 100 degreesC. The oxidation is carried out in situ. At least two controlled oxidation stages are carried out with an oxidizing fluid containing 0.4-1.5% oxygen at a temperature of 420-490 degreesC for at least four hours in the first stage, and a higher oxygen concentration of 1.3-2.0% at a temperature of 420-490 degreesC for at least two hours in the second stage.

Title: Process for further purifying a nitrogen-rich feed involves adding a single column to a cryogenic distillation air separator producing a gas which is ninety percent or more nitrogen
Inventor: GUILLARD ALAIN
IPC: F25J3/02
Filed: 2002-05-24
Abstract: Process for further purifying a nitrogen-rich feed involves adding a single column to a cryogenic distillation air separator producing a gas which is ninety percent or more nitrogen. The feed flow is heated in an exchanger in the first air separator and cooled in another exchanger (E1) before it is sent to the single column.  A flow from a first air separator (35) which is 90% (preferably 95%) N2 is compressed and fed to a single column (K1) with a head condenser (E2). It is distilled to obtain fluids relatively rich in N2 and in O2 and a flow with at least 95% (preferably 97%) N2 is taken from the column above the inlet. The inlet flow is heated to at least ambient temperature. At least part of the feed gas or gas from the single column is expanded through a turbine (T1, T2), whilst another part of the feed gas is sent to a consumer unit (23) for 90% N2, in particular upstream of the turbine. Upstream of the consumer unit the 90% gas is compressed and some is sent to the single column. The feed to the single column comes from the medium pressure and/or the low pressure column of a double column or from the high pressure and/or intermediate pressure and/or low pressure column of a triple column and/or a mixing column. Part of the base liquid (7) from the single column is expanded and sent to the head condenser of the single column where it vaporizes to form a gas flow containing less than 90% N2, which is expanded in a turbine (T2). At least part of the feed is suppressed in a suppressor (C1, C2) and then part (5) is expanded in a turbine (T1) before being sent to the single column. The turbine (T2) expanding the gas with less than 90% N2 is coupled to the higher inlet temperature suppressor (C2) and the turbine (T1) expanding the feed gas is coupled to the lower inlet temperature suppressor (C1).
