Title: System for pre-distorting an input signal for a power amplifier using non-orthogonal coordinates
Inventor: PERTHOLD RAINER
IPC: H03F1/32
Filed: 2000-02-24
Abstract: A circuit for pre-distorting an input signal v to be transmitted via a power amplifier having a non-linear transmission characteristic to produce a pre-distorted input signal y comprises an estimator (10) for determining an estimation signal (22) based on the power of said input signal v. A look-up table (20) is provided for storing complex pre-distortion coefficients BR and AI which depend on the power of the input Signal v and the non-linear transmission characteristic of the power amplifier determined in advance. For BR, the relation BR=AR-K, K being a constant with 0<K <2 applies, and AR and AI are the real and imaginary parts of a complex pre-distortion function which provides a pre-distortion of the input signal v such that the distortion introduced by the non-linear transmission characteristic of the power amplifier is substantially compensated according to magnitude and phase. Finally, a pre-distorter is provided in order to pre-distort the input signal according to y=v.(K+BR+jAI).

Title: Cage-type intervertebral implant
Inventor: MORET OLIVIER
IPC: A61F2/00
Filed: 2001-03-21
Abstract: The invention relates to a cage-type intervertebral implant that is made up of a dished side wall (1), a cambered side wall (2), a front part (3), a rear part (4) and at least one intermediate wall (5, 6), thus comprising at least two cavities (7, 8, 9). An upper and a lower cage surface (10, 11) include a first lordosis angle (alpha1) in the direction front part-rear part and a second lordosis angle (alpha2) perpendicular thereto, said cage surfaces (10', 11) intersecting outside the cage. The cage structure is characterized by a double-wedge geometry (double-wedge-shaped cage) that is defined by the two lordosis angles (alpha1) and (alpha2) and that advantageously adapts itself to the anatomical conditions in the intervertebral area. The cage is further characterized by a high moment of tilt that effectively counteracts a tipping of the cage. The method used for producing the cage structure is essentially characterized by working the cage material by means of a high-pressure water jet, said cold-cutting technique having proved to be the most economical.

Title: Freestanding reactive multilayer foils
Inventor: WEIHS TIMOTHY P
IPC: B23K35/02
Filed: 2001-05-01
Abstract: Reactive foils and their uses are provided as localized heat sources useful, for example, in ignition, joining and propulsion. An improved reactive foil (14) is preferably a freestanding multilayered foil structure made up of alternating layers (16, 18) selected from materials that will react with one another in an exothermic and self-propagating reaction. Upon reacting, this foil supplies highly localized heat energy that may be applied, for example, to joining layers, or directly to bulk materials that are to be joined. This foil heat-source allows rapid bonding to occur at room temperature in virtually an environment (e.g., air, vacuum, water, etc.). If a joining material is used, the foil reaction will supply enough heat to melt the joining materials. If no joining material is used, the foil reaction supplies heat directly to at least two bulk materials, melting a portion of each bulk, which upon cooling, form a strong bond. Additionally, the foil (14) may be designed with openings that allow extrusion of the joining (or bulk) material through the foil to enhance bonding.

Title: Formage a froid
Inventor: BLAZLEY WADE HYLTON
IPC: B21D13/08
Filed: 1998-03-18
Abstract: L'invention concerne un procédé qui permet de former à froid en continu une bande de matériau, afin de produire des éléments de construction présentant des nervures transversales sur au moins une partie de leur surface. Former à froid des éléments de ce type est souvent difficile à cause de la tendance inhérente d'une bande mince à se tordre et à se déformer quand elle sort du système de formage des nervures transversales. La présente invention résout ce problème en proposant un système de libération des contraintes, qui permet d'appliquer une charge de compression sur les nervures transversales immédiatement après chaque paire de rouleaux formant lesdites nervures. Le système de libération des contraintes comprend un premier système rouleau et un second système rouleau, qui forment une pince pouvant recevoir la bande nervurée (8). Chaque système rouleau est disposé de façon à entrer en contact avec une partie crête externe de chaque nervure (5) qui se projette vers lui. Le second système rouleau est constitué d'une paire de seconds rouleaux (14, 15) séparés, coextensifs et sensiblement parallèles, et le premier système rouleau est constitué d'un premier rouleau (16) sensiblement parallèle, coextensif et équidistant par rapport à chacun desdits seconds rouleaux (14, 15).

Title: Method for dewaxing of residual refine
Inventor: KAZAKOVA LJUDMILA P
IPC: C10G73/10
Filed: 1988-06-30
Abstract: The method is used in the petrochemical production of mineral oils, paraffins and ceresines. The method achieves an increased output of deparaffinated oil (in excess of 64 percent), reduces the solidification temperature (below -12 degrees C) and increases the filtration rate (over 2.2 m<3>/m<2>.h). The method involves mixing residual raffinate with a solution at a ratio of 1:10 to 1:15 basis the feedstock mass. The solution represents an acetone/toluene mixture at a ratio of 40:60 percent by volume. To the mixture 0.002 - 0.007 percent aluminium salt of nitrated viscous oil base component, BK-1 or BK-2, is added. The additive is prepared by nitrating the corresponding oil distillate with 63 +- 3 percent nitric acid under the following conditions: distillate / nitric acid ratio 1:1, temperature 20-40 degrees C, duration 3-5 hours. The nitration products are neutralized with aluminium hydroxide. After introducing the additive, the mixture is heated up to 45-55 degrees C, cooled down to 25 degrees C at an average rate of 120 - 150 degrees C per hour and vacuum-filtrated with a residual pressure of 300 - 320 mm Hg.

Filed: 1989-10-12
Abstract: PULTRUSION SYSTEM FOR CONDENSATION RESIN INJECTION   ABSTRACT        A composition, apparatus and method for making resin bonded composite pultruded products using a thermosetting resin is disclosed.  The resin comprises a condensation resin which has a high solids content. A pultrusion system comprises reinforcing material supply, a pultrusion die adapted to be heated, injection device for injecting resin into the die, and pulling device for drawing product through the die. The method comprises supplying strands of the reinforcing material to the die and grasping the strands with the pulling device, injecting a condensation-type monomer resin into the die to impregnate the reinforcing material within the die, and pulling the resin-impregnated strands through the die at a rate that permits the resin to condense to an essentially cured state by the time the composite product is withdrawn from the die.  The die is a modular die such that various sections of the die may be selected as desired to change process parameters. The die is divided lengthwise into a plurality of regions or sections, typically comprising an entry section, a resin injection section, a transition section and a profile section, which are joined together to create the desired die characteristics. Also disclosed is an adaptation die to convert a conventional non-injection die into an injection die. The adaption die comprises an entry section, a resin injection section and a transition section adapted for connection to the conventional die.
