Patent EP-1119541-B1 (EP)
Inventor: PASCHKE EDWARD E
IPC: C08G63/189
Filed: 1999-10-05
Granted: 2003-07-23
Abstract: Processes for producing aromatic monomers useful for forming polyesters are disclosed. Cost effective steps employed in the processes permit small amounts of process-related materials typically removed from monomer to remain in an aromatic monomer product. In many cases, the presence of the process-related materials left in the monomer product by the cost effective process steps can enhance the performance of the monomer in certain applications. Aromatic monomer products and polymers produced therefrom having these advantages also are disclosed, as well as products such as pasteurizable bottles made from these polymers.

Abstract: Apparatus for detecting a metal object comprises a transmitter for generating a pulsed or an alternating magnetic field in the vicinity of the metal object to be detected and a detector for detecting the secondary magnetic field induced in the metal object by the transmitted magnetic field. The detector measures at least three magnetic field gradient components of at least first order of the secondary magnetic field. The apparatus also comprises a processor for determining at least one of the position or the electro-magnetic cross-section or an estimate of the shape of the metal object from the measured magnetic field spatial gradient components. The processor fits the measured components to dipole, multiple dipole, multipole, or extended source models. In a preferred embodiment, the invention may comprise three or more pairs of gradiometric coils, or other sensing means. The detector measures at least five magnetic field gradient components of at least first order, and one or more components of the secondary magnetic field. The detector may be coils, or any other magnetic sensors. The processor enters pre-determined criteria to discriminate against detection of metal objects of no interest or to selectively detect metal objects of interest.

Abstract: A two-stage seal, such as a ring seal for use in a pressurized process fluid line, has a dynamic sealing member (62, 64) and a static sealing member (66, 68). The dynamic sealing member is arranged to continuously sealingly engage against a seal surface that slides along the dynamic sealing member. The static sealing member is arranged to sealingly engage against the seal surface in response to an increased process fluid pressure within the process fluid line to increase static seal pressure against the seal surface. The static sealing member is also arranged to release from the seal surface to minimize friction with the seal surface when the process fluid pressure drops and/or in response to movement of the seal surface. The two- stage seal may be used in arrangements requiring both dynamic sealing and static sealing, such as in some process control valves. A process control valve having the two-stage seal is disclosed.

Purging nitrogen may be supplied via controlled inlets 144 to the vestibules, which have controlled outlets 152 to the atmosphere. Hydrogen may also be supplied to the transfer station 180 through line 119 and valve 187 and to the vestibules through lines 142 and 116 and manifolds 144. A line 132 with valve 181 connects zone 8 with the other heating zones. Atmosphere gas withdrawn through headers 112 and 170 is returned to the reconditioner 110 where contaminants are removed and the gas is cooled. Headers 121 and 125 in the cooling sections are also used to withdraw atmosphere gas which is returned to roof jets 74 from coolers 122 and 126. A container 138 replaces hydrogen lost by leakage. Heating elements in the form of molybdenum rods (58, Figs. 2 and 3) are mounted on the walls in the heating sections and the refractory on said walls is gradually narrowed in the cooling sections until in the last of these it is nil. The coil carrying truck 40, Fig. 9, comprises lower layers of refractory 82, 84 with an upper layer formed with radiation tunnels 86 about the level of the heating elements, surmounted by silicon carbide tiles 90 and a hearth plate 92 of low carbon steel with a coating of alumina. In these layers a vertical hole (94, Fig. 10) in line with the centre coil opening 104 communicates with the radial radiation tunnels 86. A tube 95 carries a thermocouple 96 extending to a plug-in point 97 below the truck.
