Title: Installation and process for the preparation of urea
Inventor: MENNEN JOHANNES HENRICUS
IPC: B01J12/00
Filed: 2001-01-29
Granted: 2010-05-18
Abstract: The invention relates to an installation for the preparation of urea from ammonia and carbon dioxide, the installation comprising two reactor sections in a vertically placed combined reactor and a high-pressure condenser section. The installation may comprise a vertically placed combined reactor, with the two reactor sections being separated by a high-pressure condenser section.  In another embodiment the installation comprises a vertically placed combined reactor that comprises two reactor sections and a high-pressure condenser section placed outside the reactor. The invention also relates to a process for the preparation of urea in this installation. This involves feeding the gas stream leaving the stripper wholly or partly to the high-pressure condenser section of the installation. Preferably, a portion of the gas stream leaving the scrubber is fed to the second reactor section in the vertically placed combined reactor via an ammonia-driven ejector.

Title: Spectrally resolved detection of ionizing radiation
Inventor: FRANCKE TOM
IPC: H01J47/02
Filed: 2001-01-12
Granted: 2008-04-01
Abstract: Spectrally resolved detection of ionizing radiation in a detector comprising a chamber (13) filled with an ionizable substance, a radiation entrance (33), an electron avalanche amplification means, and a read-out arrangement (29), comprises introducing a broadband radiation beam (1) into the chamber between and in parallel first and second electrode arrangements for ionization of the ionizable substance and avalanche amplifying said electrons.  By means of the read-out arrangement (29) electron avalanches (S X1, S X2, ..., S XN), derivable mainly from ionization in sections (X1, X2, ..., X N) of the chamber that are separated in the direction of the introduced radiation beam, are separately detected. From spectrally resolved absorption data, weighting factors (W11, W21, ..., W M1, W12, W22, ..., W M2, ..., W1N, W2N, ..., W MN) for different spectral components (E1, E2, ..., E M) of the radiation (1) and for different sections (X1, X2, ..., X N) of the chamber are deduced, each of said weighting factors being substantially proportional to the photon flux (.PHI.17, .PHI.21, ..., .PHI.M1, .PHI.12., .PHI.22, ..., .PHI.M2, ..., .PHI.1N, .PHI.2N, ..., .PHI.MN) of the respective spectral component (E1, E2, ..., E M) in the respective section (X1, X2, ..., X N). Finally, by means of said detected electron avalanches (S X1, S X2, ..., S XN) and said weighting factors, the respective detected electron avalanches (S E1, S E2, ..., S EM) that are derivable from ionization by the respective spectral component of said broadband radiation are deduced.

Abstract: An animal feeder includes a hopper above a shelf onto which feed can fall to be taken by the animal or dropped into a trough below the shelf. The height of the shelf is adjustable to change the width of the opening through which the feed passes to control feed rate. The shelf is carried on straps which extend along the end walls of the hopper and are movable by an adjustment linkage defined by a plate carried on the end wall and a manually adjustable lever mounted for pivotal movement on the plate. The plate has an arcuate outer edge which is serrated to define an arcuate row of saw teeth and the lever is formed by a flat of sheet material which lies in a plane parallel to and slides over the plate and includes a portion thereof which is bent out of a plane of the lever into the plane of the plate which is also serrated with a row of saw teeth shaped to mesh with the saw teeth of the arcuate portion. The portion of the lever is movable in a direction away from the plate a non-meshing position in which the lever is free to move around the pivot axis.

Granted: 2009-12-01
Abstract: A method for detecting the presence of particles, such as sand, flowing within a fluid in a conduit is disclosed. At least two optical sensors measure pressure variations propagating through the fluid. These pressure variations are caused by acoustic noise generated by typical background noises of the well production environment and from sand particles flowing within the fluid. If the acoustics are sufficiently energetic with respect to other disturbances, the signals provided by the sensors will form an acoustic ridge on a k.omega. plot, where each data point represents the power of the acoustic wave corresponding to that particular wave number and temporal frequency. A sand metric then compares the average power of the data points forming the acoustic ridge to the average power of the data points falling outside of the acoustic ridge. The result of this comparison allows one to determine whether particles are present within the fluid. Furthermore, the present invention can also determine whether the generated acoustic noise is occurring upstream or downstream of the sensors, thus giving an indication of the location of the particles in the fluid relative to the sensors.

Abstract: Sheet material is made from a mixture of base fibres, such as leather fibres, and bi-component synthetic fibres which have outer layers which melt at a lower temperature than their inner cores. The fibres are mixed, formed into a web and then heated so that the synthetic fibres fuse together to form a network within the web. The base fibres are then tangled, whilst constrained by the network, preferably using hydroentanglement. A high quality reconstituted leather sheet material can be produced.

Abstract: A top-supported sliding door system or a vertically sliding door system achieves an enhanced air seal with a lateral keeper mechanism on either or both of the trailing and leading edges. On an outward lateral edge of a door panel, a keeper projects inwardly toward the doorframe to engage a doorframe camming surface such as a pin. The bracket may advantageously disengage under a force indicative of impact in order to minimize damage resulting therefrom. Application of the lateral keeper mechanism may further be used on vertically sliding doors and on multi-panel horizontal sliding doors. In addition, a rail may extend from the angled pin to engage the keeper throughout the full travel of the door panel.

Title: Method and device for evaluating physical parameters of an underground deposit from rock cuttings sampled therein
Inventor: LENORMAND ROLAND
IPC: G01N15/08
Filed: 2003-02-19
Granted: 2010-02-16
Abstract: The invention concerns a method and a device for evaluating simultaneously and with the same equipment, physical parameters such as absolute permeability and porosity, of fragments extracted from a fragmented natural or artificial porous environment. It consists in measuring the porosity of the fragments with helium pressure tests in accordance with a protocol known per se. The enclosure (1) which contains them is communicated with a reservoir (11) of volume likewise known per se, containing helium under pressure known per se. From the equilibrium of the pressures can be deduced the value of the solid volume. The rock envelope volume and the mass of fragments are also measured. By combining those measurements, the porosity of the samples as well as the rock density is determined. Then their permeability is measured by immersing them in a viscous fluid and communicating the enclosure with the viscous fluid under specific pressure contained in a container (9) so as to compress the gas trapped in the pores of the rock, in accordance with two different protocols. By modelling the evolution of the pressure or the volume in the enclosure, and iterative adjustment, the values of the physical parameters are determined. The invention is applicable, for example, to petrophysical measurements from bore cuttings or crushed cores.
