Abstract: Method for conversion of hydrocarbons assisted by gliding electric arcs in the presence of steam and/or carbon dioxide. The objective of the process and the plasma assistance device to steam reforming, to the reforming with CO2 or to simultaneous reforming with an H2O/CO2 mixture of hydrocarbons is the production of gases rich in CO and H2, containing also high ratios of C2H2, C2H4 and C3H6, without formation of soot or coke. The process makes it also possible to upgrade the CO2 by converting it into CO in the presence of hydrocarbons. This mixture of valuable; products is obtained in a reactor /1/ with electric gliding arcs /4/ which strike directly into an endothermic reaction medium consisting of hydrocarbons mixed with H2O and/or CO2. The reactor is equipped with a diaphragm /19/ with a convergent/divergent hole /20/ to reinforce the agitation of the arcs with the load to be converted and, at the same time, to have the conversion of the load progress after prolonged contact with catalytic species derived from the plasma.

Title: Transition controlled balanced encoding scheme
Inventor: LEE KYEONGHO
IPC: H04N7/52
Filed: 1997-03-25
Abstract: A method and apparatus for producing a transition-controlled, DC-balanced sequence of characters from an input sequence of data bytes is disclosed herein. The bits in each of the data bytes are selectively complemented in accordance with the number of logical '1' signals in each data byte in order to produce selectively complemented data blocks. A cumulative disparity is then determined between the logical values of different type included within ones of the selectively complemented data blocks previously encoded into characters. In addition, a current disparity in a candidate character associated with a current one of the selectively complemented data blocks being encoded is also determined. The candidate character is assigned to the current one of the selectively complemented data blocks if the current disparity is of a polarity opposite to a first polarity of the cumulative disparity. Alternately, the complement of the candidate character is assigned to the current one of the selectively complemented data blocks if the current disparity is of the first polarity. In a high-transition mode of operation, the bits within data blocks including fewer than a minimum number of logical '1' signals are selectively complemented so that each such selectively complemented data block includes in excess of the minimum number of logical transitions. In a low-transition mode of operation, the bits within data blocks having more than a predefined number of logical '1' signals are selectively complemented so that each such selectively complemented data block includes less than the maximum number of logical transitions.

Abstract: Cette invention décrit de nouveaux procédés de fabrication de compositions d'élastomère, dans lesquels on utilise notamment certains agents modificateurs et un traitement mécanique avant l'incorporation d'un système de vulcanisation dans la première ou une des premières étapes d'un processus à plusieurs phases d'une matière de charge particulaire, comme le noir de carbone. Un agent de réticulation au soufre est ensuite largement dispersé dans un élastomère d'hydrocarbure réticulable par le soufre. La matière de charge particulaire et l'agent de réticulation au soufre peuvent être préalablement apprêtés ensemble pour donner un prémélange que l'on ajoute à l'élastomère. A l'issue du processus à plusieurs phases, on obtient un élastomère largement non vulcanisé et apte au traitement, impliquant un nouveau traitement mécanique du mélange monté de départ. Un additif de vulcanisation comprenant un accélérateur et, éventuellement, un agent additionnel de réticulation au soufre peut être ajouté et dispersé dans l'élastomère pour donner une composition vulcanisable. Dans un autre aspect, de l'huile de charge est ajoutée à l'élastomère après ajout et dispersion substantielle de la matière de charge particulaire et de l'agent de réticulation au soufre dans l'élastomère pendant lesdites premières phases du processus. Des améliorations significatives des caractéristiques de performance sont obtenues, en particulier par des formes d'exécution préférées, y compris une bonne résistance à l'abrasion et un faible hystérésis mesuré, par exemple, comme tan .delta.¿max? à 70 ·C. La présente invention concerne en outre de nouvelles compositions d'élastomère non vulcanisé, aptes au traitement et comprenant certaine matière de charge particulaire traitée, le noir de carbone, et certain modificateur de pré-vulcanisation en quantités propres à accroître substantiellement la teneur en caoutchouc lié d'un produit élastomère sensiblement non vulcanisé et apte au traitement, obtenu après un traitement thermomécanique improductif de la composition d'élastomère.

Patent CA-2268572-A1 (CA)
Inventor: MASON RALPH DICKSON
IPC: G01R1/073
Filed: 1999-04-12
Abstract: Methods for (a) testing an integrated circuit wafers and (b) creating integrated circuit dice assemblies using wafers are taught herein. Two integrated circuit wafers (1,2) are directly attached together using conductive bumps bonds (8), unlike other proposed methods that use a plurality of test dice and/or intermediate connection layers. The wafers are designed with matching glass openings (7) and bump bond pads (5) to provide a large number of connections between the wafers that have low resistance, capacitance and inductance. For testing purposes, one of the wafers (2), referred to herein as the test wafer, can be designed with embedded test circuitry that can be used to simultaneously test one or more of the integrated circuit designs on the second wafer (1), referred to herein as product wafer number one. The test wafer can be coupled to an external tester using either probes (3), conductive leads or bump bonds. After testing, the wafers are detached and the bump bonds are reflown for subsequent assembly. For assembly purposes, the same method can be used in which the test wafer is replaced with a second product wafer, referred to herein as product wafer number two. The two product wafers can hame different circuits and possibly different semiconductor processing technologies. Unlike other proposed methods, the product wafers are directly connected to one another with bump bond and require no intermediate connection layer. The product wafers are then cut into dice assemblies (12). Unused sections of the product wafers (13) are discarded. Unlike other proposed methods, this allows a large number of die assemblies to be created simultaneously without precision handling of individual dice. The resulting dice assemblies contain dice (6,9), one or more from each wafer, that are connected by the bump bonds. The dice assemblies can then be connected to external circuits using bump bonds (10) or conductive leads. In a modified assembly method, product wafer number one is first cut into dice which are then attached to product wafer number two. This modification provides higher yield in dice assemblies by selecting known good die. The disadvantage is more complex assembly using dice instead of only full wafers.

Title: Method for testing the stability of vertically braced masts
Inventor: ROCH OLIVER
IPC: G01M5/00
Filed: 1998-01-09
Abstract: The invention relates to a method for testing the stability of vertically braced masts wherein the relevant mast is subjected to the load of a bending force starting from a defined initial value, and increasing to, at most, a maximum pre-set testing force above its bracing, said mast thereby being laterally displaced. Subsequently, on termination of the load test procedure, said load is removed from the mast, whereby it is subjected to a restoring force which reduces to zero. Possible remaining lateral displacement of the mast as the restoring force returns to zero is determined and evaluated in conjunction with the load removal procedure to determine damage to the mast and/or its bracing. In order to further determine the type of damage to the mast, the mast is subjected to an additional bending force in the opposite direction of the first bending force, and then the load is once again removed from the mast in a second test procedure. In this case a possible remaining displacement of the mast/bracing system must be determined.      The determined remaining displacements are evaluated in conjunction with the highest mast loads to determine the type of possible damage to the mast.
