Title: Recirculation structure for a turbocompressor
Inventor: SEITZ PETER A
IPC: F02C7/04
Filed: 2003-08-21
Abstract: Disclosed is a recirculation structure for a turbocompressor, comprising an annular chamber which is arranged in the area of the free blade ends (25 to 28) of a blade ring and radially borders the main flow channel (29 to 32), and a plurality of guiding elements (37 to 40) which are disposed inside the annular chamber and are spread across the circumference thereof. Said annular chamber allows the flow to penetrate in the circumferential direction in the front and/or rear area. The guiding elements are connected in a fixed manner to at least one wall of the annular chamber but are detached everywhere else.  The tips of the guiding elements, which face the annular chamber, run on and/or near the contour of the main flow channel while axially overlapping the free blade ends or axially bordering the area of the free blade ends.

Abstract: A steel product having a structure composed mainly of ferrite or ferrite plus pearlite or ferrite plus cementite. A steel pipe produced from this steel product by rolling at a ferrite recrystallization temperature such that the reduction of area is greater than 20%. This steel pipe is characterized by grain size not greater than 3 µm, preferably not greater than 1 µm, elongation greater than 20%, tensile strength (TS : MPa) and elongation (E1 : %) whose product is greater than 10000, and percent ductile fracture greater than 95%, preferably 100%, measured by Charpy impact test on an actual pipe at -100 °C. The structure is characterized by C : 0.005-0.03%, Si : 0.01-3.0%, Mn : 0.01-2.0%, and Al : 0.001-0.10% on a weight basis, and is composed of ferrite or ferrite and a secondary phase, with ferrite grains being not greater than 3 µm and the secondary phase having an areal ratio not more than 30%. The steel pipe is produced from a steel pipe stock having the above-mentioned composition by heating at a temperature of (Ac1 + 50°C) to 400°C and subsequently performing reducing on it at a rolling temperature of (Ac1 + 50 ° C) to 400 ° C such that the cumulative reduction of diameter is greater than 20%. The reducing is preferably performed such that at least one of rolling passes reduces the diameter by more than 6% per pass. The steel pipe will have high ductility and high strength and will be superior in toughness and stress corrosion cracking resistance, if the content of C, Si, Mn, and other alloying elements is limited low and reducing is performed at the temperature specified above. The resulting steel pipe has good fatigue resistance and is suitable for use as line pipe.

Abstract: On applique un cathéter à ballonnet pour le traitement du système lacrymal d'un patient de manière transnasale sans qu'il soit nécessaire de faire appel à un fil guide ou à un élément de retenue courbe. Le cathéter est constitué d'un hypotube en acier inoxydable et présente une rigidité et une résistance en colonne suffisantes pour pousser le cathéter dégonflé depuis la cavité nasale du patient à travers une petite ouverture préparée étanche pratiquée à travers la paroi nasale latérale et la fossette lacrymale en direction du sac lacrymal. Le cathéter présente une tige proximale et un segment distal fléchi selon un angle de 70· à 115·, de préférence 90·, vers la tige proximale. Un élément gonflable est monté autour du segment distal et est lié de manière adhésive à l'extrémité distale de la tige proximale, le cintre et l'extrémité proximale du segment distal et à la partie distale du segment distal. On obtient la petite ouverture préparée étanche en poussant de petits orifices à travers le cul-de-sac médial, la fossette lacrymale et la paroi nasale latérale à l'aide d'un instrument et en coalesceant des orifices afin de former ladite ouverture. Le cathéter est introduit dans la cavité nasale et tourne, ou se déplace, de manière à aligner le segment distal sur l'ouverture préparée. Le segment distal est ensuite poussé à travers l'ouverture préparée et on applique un fluide sous pression sur le cathéter afin de gonfler l'élément gonflable et de dilater l'ouverture préparée.

Inventor: REDDEN ROBERT F
IPC: B01D9/00
Filed: 2005-03-31
Abstract: A temperature- and evaporation-controlled device for the crystallization of proteins from a protein-containing solution. The device comprises a compartment, such as a microcapillary tube, for holding the solution from which crystals are formed. The compartment is in communication with a cold generating unit, such as a cold finger, that maintains a temperature lower than the temperature of the compartment thereby causing de-watering of the solution. A vacuum pump can be attached to the device to reduce vapor pressure to further promote de-watering of the solution. The device can be used terrestrially or in a microgravity environment, such as in outer space, for formation of high quality protein crystals.

Title: Interlock mechanism for lateral file cabinets
Inventor: HOFFMAN KEITH
IPC: E05B65/466
Filed: 2003-11-26
Abstract: The invention relates to interlocks for file cabinets and the like which generally prevent more than one drawer from being opened at a given time. The interlocks include a cable which is changeable from a slack condition to a taut condition. In the taut condition, the interlocks prevent the associated drawer from being opened. In the slack condition, the interlock allows the associated drawer to be opened. The interlocks may be used in conjunction with a lock that selectively changes the tension in the cable from a slack condition to a taut condition and vise versa. The interlocks may be constructed to exert a tension on a cable that is independent of the pulling force exerted on a locked drawer. Alternatively, the interlocks may be constructed to exert a force on the cable that is a small fraction of the pulling force exerted on a locked drawer.

Title: Direct synthesis method for the production of etherified melamine resin condensates, melamine resin condensates, and use thereof
Inventor: TAPPEINER GUENTER
IPC: C08G12/42
Filed: 2003-12-18
Abstract: The invention relates to a direct synthesis method for producing etherified melamine resin condensates having average molar masses of 500 to 50,000. Said method is characterized by the fact that a) an etherified melamine resin precondensate is produced in an alcoholic solution in a first reaction step; b) the etherified melamine resin precondensate is concentrated in an alcoholic solution in at least one condensation step, C4 to C18 alcohols, diols of type HO-R-OH, and/or tetravalent alcohols that are based on erythritol being added to the melamine resin precondensate during and/or following the concentration process; c) the concentrated melamine resin precondensate is reacted by means of a mixer, especially a kneader, in a second reaction step. The inventive method allows melamine resin condensates having average molar masses of 500 to 50,000 to be produced, said melamine resin condensates being free of hydroxymethyleneamino groups that are bonded to the triazine rings and -NH-CH2-O-CH2-NH- groups which link the triazine rings.

Abstract: A loader leveling device such as used for a loader bucket mounted on a tractor or similar device consists of a pair of spaced lift arms which are secured at their inner ends to the tractor and at their outer ends to the bucket or similar mechanism. These lift arms are provided with a series of connecting links between their inner ends and the outer ends supporting the bucket and these connecting links form a set of parallelograms utilizing bell cranks or pivot plates at their extreme ends and intermediate thereof.  Hydraulic actuators are used to raise or lower the lift arms and the connecting links, through the bell cranks, maintain the bucket at a constant level. However, a secondary, cylinder frame interconnects the rear surface of the bucket with the lift arms and tilt cylinders mounted to the cylinder frame and the bucket can be used to rotate the bucket relative to the lift arms. The present invention provides an advance in this art through the separation of the tilting cylinders from the linkage that is associated with the lift arms for raising and lowering the bucket.
