Patent EP-0494007-A1 (EP)
Inventor: GIRAULT JEAN-PHILIPPE
IPC: F02K9/48
Filed: 1991-12-20
Abstract: The turbopump comprises, inside the same casing (102), a main shaft (101) driven by a turbine (103), a secondary shaft (104) coaxial with the main shaft (101), a low pressure impeller (110) mounted on the secondary shaft (104) in order to create a medium pressure outflow which is brought back parallel to the axis of the turbopump by a diffuser (111) and turned through 180 DEG  in a return channel (112) in order to be brought back parallel to the axis of the turbopump towards a high pressure impeller (114) mounted on the main shaft (101) inside the secondary shaft (104). All of the centrifugal HP outflow shaped by the HP impeller (114) is sent to the interior (133) of inwardly curved hollow blades (132) forming part of the LP impeller (110). This centrifugal HP outflow creates a driving torque for the LP impeller (110).

Abstract: A control unit for an electric drive motor of industrial processing machinery includes a control arrangement which drives a pair of magnets (30) generating a magnetic flux and a Hall effect sensor (34) disposed between the magnets (30) so as to be swept by the magnetic flux rotatively with respect to each other; the Hall effect sensor (34) outputs an electric signal which varies consistently with the position setting of the control arrangement and drives the electric motor (35) accordingly; the movement of the control arrangement is resisted by springs (55,56,57) having different degrees of stiffness from one another; proper interaction can thus be established between the operator and the machine.

Abstract: Un outil pour forage à percussion et forage rotatif en aval d'un tubage traînant (20) comporte un trépan aléseur (15) tourillonné de manière pivotante sur un arbre excentrique (12) à l'arrière d'un trépan pilote central (11). Le trépan aléseur (15) présente une partie excentrique (12) portant des éléments rapportés circulaires en métal dur (36-40) dirigés axialement et groupés à l'intérieur d'un angle aigu (V) d'un secteur de cercle centré sur l'axe de forage (C). Les éléments rapportés comprennent des éléments rapportés primaires (36-38) dotés d'une portée radiale définissant le diamètre extérieur du trou foré, et des éléments rapportés secondaires intérieurs (39, 40) plus proches de l'arbre (12). Le trépan aléseur (15) pivote sur l'arbre (12) entre une position déployée et une position rétractée. En position déployée, le groupe d'éléments rapportés circulaires (36-40) alèse le trou pour le faire passer du diamètre foré par le trépan pilote (11) au diamètre extérieur du trou permettant l'avance du tubage (20). En position rétractée, l'outil de forage (10) peut passer à travers le tubage (20). Deux éléments rapportés (36, 39) avançant dans le sens rotatif agissent conjointement pour briser la roche dans ladite direction de manière sensiblement tangentielle par rapport à l'arbre (12). Les déblais de la roche taillée par les éléments rapportés circulaires (36-40) sont soumis à une action de rinçage renforcée. Eventuellement, cette action de rinçage est également améliorée par une rainure (52) ménagée sur le flanc d'attaque rotatif du trépan aléseur (15). Un bord tranchant (54) ménagé sur la rainure (52) est renforcé par de la stellite et améliore le forage dans un terrain argileux.

Abstract: An oral or nasal inhalation device comprises an air passageway (22) optionally shaped as a venturi passing through a body (20). A holder (40) on the body receives a single dose powder container (60) containing a medicament. A piercer (26) or needle having a bore therethrough extends from the body into the holder. The user places the container and removes a seal on the top end of the container. Alternatively, the piercer is longer than the container and pierces both ends of it, obviating the need for a removable seal (62). A sharp inhalation causes air to be drawn through the air intake (27), creating a partial vacuum in the air passageway and causing the powder to be dispensed from the container through the bore of the piercer. Another embodiment has two piercers, each acting on an end of the container. Further embodiments make use of a rotable disk provided with multiple containers.

Abstract: Oxygen is added to the gas to be desulphurised, which contains H2S and steam, so that the gas contains, per mol of H2S, 1 to 20 mol of O2. At temperatures in the range from 50 to 180 DEG C, the gas is passed over activated carbon, the activated carbon becoming loaded with elementary sulphur and also with up to at least 3% by weight of sulphuric acid. It is expedient to first pass the gas to be desulphurised, the content of H2S + SO2 in which is at least 1000 ppm, through a catalytic prepurification at temperatures of 100 to 180 DEG C, elementary sulphur being adsorbed onto a metal oxide-rich catalyst. Oxygen is admixed to the gas leaving the prepurification and the gas, at temperatures of 50 to 180 DEG C, is passed over the activated carbon to complete desulphurisation.

Abstract: A monochromator 18 has a thin faceplate which reduces temperature-induced distortion in a strain-free region by placing it close to a two-level heat exchanger 46, 64. The heat exchanger has a first level 46 in juxtaposition with the faceplate 22 for efficient heat extraction, and a second level 64 which establishes a constant temperature plane along a neutral bending axis of the monochromator 18. The first level heat exchanger is operated at a temperature below the zero CTE point of the silicon faceplate so that the integrated CTE of the faceplate is approximately zero. Pumps 30 and 32 are disposed respectively at the coolant inlets 26 and outlets 28 for fine-tuning the coolant pressure so that a minimal pressure across the faceplate 22 may be established to minimize bending moments on the thin faceplate. The upper and lower heat exchangers 46, 64 are comprised of a plurality of micro-channels which are divided into groups, each group associated with a macro-channel 40, 60 and a return plenum 48, 68 which tapers down to an orifice 50, 72, which is connected to a return header 52, 74. The sizes of the orifices 50, 72 may be adjusted to control the amount of coolant flow through each macro channel so that the cooling provided may be matched to the heat absorbed by the faceplate.

Abstract: A superconducting magnet for use in a particle accelerator of the synchotron type is disclosed. The disclosed magnet includes twin bores (4a, 4b), each having beam pipes (2a, 2b) therein. A flux pipe (14) is provided between the twin bores such that a 360° magnetic flux path is formed. A superconducting coil (8) encircles the bores and flux pipe, for generating the transverse magnetic field across the beam pipes. The flux pipe (14) may be formed of non-magnetic material for a linear magent, or alternatively may be formed of ferromagnetic laminations (22) parallel to the direction of the magnetic field to form a superferric magnet with minimal eddy current generation. The flux pipe includes magnetic stress relief bubbles (12) near the bores, compensating for the crowding effect near the inner radius of the flux pipe. Bands (20) are provided around the magnet, including filler material (16) therewithin, which are formed of a material having a high coefficient of thermal expansion; upon cooldown of the magnet, the contraction of the bands applies an inward prestress force upon the coil, counteracting the inverse Lorentz forces generated by the magnetic field.
