Title: Terminal block for high transmission rates
Inventor: BEUTLER PETRA
IPC: H01R13/6471
Filed: 1996-07-31
Granted: 2002-10-01
Abstract: The present invention relates to a terminal block for high transmission rates in telecommunications and data processing. The terminal block has a plastic body with at least one row of chambers for insulation displacement contact elements. Slots for shield plates are disposed in transverse walls between the chambers, and extend with axes parallel to the walls. The object of the invention is to provide a terminal block wherein by the configuration of specially-shaped shield plates, an effective reduction of crosstalk and a substantial simplification of assembly of the shield plates and of the cable wires at the insulation displacement contact elements are guaranteed. This is achieved by disposing the chambers of a terminal unit in the plastic body at the smallest possible distance d to each other, and by providing the slots for receiving the shield plates in the transverse walls between adjacent terminal units, the slots extending from a lower side of the plastic body. The distance d between the chambers of a terminal unit are appreciably smaller than the distance D between the chambers of adjacent terminal units.

Abstract: Selon une forme d'exécution de la présente invention, un dispositif de commande à domicile reçoit des signaux d'un système de télévision par câble et utilise un démodulateur de câble accordé à la fréquence RF du canal qui transporte les informations/données. Le démodulateur du câble démodule les signaux RF codés en forme numérique, dans une bande de base usuelle, et ces signaux numériques sont transmis vers un récepteur de paquets qui décode les paquets adressés à des utilisateurs individuels. Lorsqu'un paquet est adressé à l'utilisateur, le récepteur de paquets transmet les données correspondantes, par exemple par un émetteur-récepteur ETHERNET, vers l'ordinateur personnel de l'utilisateur. On peut utiliser un dispositif de commande des communications pour assurer l'interface entre l'ordinateur personnel et le démodulateur du câble, ce qui permet à l'ordinateur personnel de choisir le canal auquel le démodulateur du câble est accordé, pour permettre l'utilisation de canaux de données multiples.

Filed: 1995-06-02
Granted: 2005-04-26
Abstract: The present invention concerns a procedure for continuous or batch production in one or possibly more steps in one or more furnaces of silicon (Si), possibly silumin (AlSi alloys) and/or aluminium metal (Al) in the required conditions in a melting bath, preferably using feldspar or feldspar containing rocks dissolved in a fluoride and process equipment for implementing the procedure. Highly pure silicon is produced by electrolysis (step I) in a first furnace comprising a replaceable carbon anode (3) located at the bottom of the furnace and a carbon cathode (1) located at the top of the furnace. For the production of silumin the Si-poor residual electrolyte from step I is transferred to a second furnace and aluminium metal is added (step II).      Aluminium metal is produced in a third furnace (step III) by electrolysis after Si has been removed in step I and possibly in step II. The present invention also concerns the production of silicon, possibly silumin and/or aluminium by using process equipment comprising two or more furnaces integrated to form one unit with (an) intermediate partition wall(s) which is/are designed to transfer the electrolyte from one furnace to another.

Abstract: As shown in Fig. 1, on a semiconductor substrate 20 formed in sequence are a second n-type clad layer 11, a first n-type clad layer 12, an n-type carrier blocking layer 13, an active layer 14, a p-type carrier blocking layer 15, a first p-type clad layer 16, a second p-type clad layer 17, a current constriction layer 18, and a p-type contact layer 19. The carrier blocking layers 13 and 15 are doped to a high doping concentration of more than 1x10 18cm -3. The first clad layers 12 and 16 and the second clad layers 11 and 17 are doped to a low doping concentration of less than 3x10 17cm -3. The p-type carrier blocking layer 15 is doped with carbon or magnesium which is low in the diffusivity. Accordingly, the carriers are successfully confined in the active layer 14 thus to suppress the internal loss and the electrical resistance, whereby a high-efficiency, high-output semiconductor laser device can be obtained.

Abstract: A method and apparatus is disclosed for the continuous calcining of gypsum material in a high-efficiency, refractoryless kettle preferably heated by a multiple series of separate immersion tube burner coils, each coil operating within a specific calcining zone inside the kettle. The lowest, i.e., initial, burner tube coil is formed with a low profile to permit use of a small initial gypsum charge, and hence, a quick kettle start-up cycle. That low profile initial burner design also helps keep the agitator motor's load at a minimum during cycle start-up. Due to the immersion tube burner coil construction, no refractory structure for the kettle is required. Also, no separate hot pit structure is required, as the kettle is used to merely hold the material bei ng calcined and no residual heat is present. A relatively thin kettle can be constructed, as it needs only withstand relatively low operating temperatures. The kettle's staged, interiorly-disposed burner tube coils act to directly transfer burner tube heat to the kettle's contents, an d the coils exhaust exteriorly of the kettle. The present calcining method and apparatus permit substantially improved tonnage output of calcine d material, for a kettle of a given size. A modification to the present apparatus includes structure for recovering and recycling a portion of the spent burner gases, and also separate structure for forced aeration air, both preferably for introduction through the kettle bottom. One alternate embodiment concerns a differently-shaped kettle design. Another altercate embodiment concerns a modified kettle which uses a single immersion burner tube coil to provide the total heating of the kettle's contents, for use in certain calcining applications.

Abstract: A p-aramid microfilament yarn and a process for manufacturing the same. In the p-aramid yarn, which has a yarn linear density of at least 300 dtex, comprising a bundle of filaments with a linear density of less than 0.8 dtex, the g value is higher than 2.5 GPa, the elongation (EAB) is higher than 3.4%, and the L002 value is higher than 350.ANG.. More particularly, the filament linear density is 0.3 to 0.8. The yarn according to the invention has surprisingly favorable properties, such as a high internal shear modulus. The invention also pertains to a process for. manufacturing such a micro-filament yarn in which p-aramid is subjected to an air gap-wet spinning process of the known type, in which the draw ratio in the air gap combined with the diameter of the capillaries through which the polymer is extruded ensures that microfilament yarn having the desired properties is obtained.

Title: Thermal shock resistant sapphire for ir windows and domes, and method of making same
Inventor: HARRIS NORMAN H
IPC: C30B31/00
Filed: 1997-08-19
Granted: 2001-01-23
Abstract: Single crystal sapphire (34) is conventionally employed for mid-wave IR windows and domes exposed to high aerodynamic heating environments. Single crystal sapphire (34), however, suffers a loss of compressive strength in the c-axis of 95% on heating from ambient to 800°C. This loss of compressive on heating results in poor thermal shock resistance. Poor thermal shock resistance jeopardizes the reliability of the windows (32) and domes. The process of the present invention strengthens sapphire (34) and improves its resistance to thermal shock by introducing magnesium (Mg) ions into the crystal lattice of sapphire (34) to form a solid solution. The solid solution increases the strength of the sapphire (34). Additionally, a larger increase in strength results from converting the Mg into second phase precipitates (40) comprising magnesium aluminate spinel. The formation of the second phase particulates (40) results in precipitation-hardening or precipitation-strengthening due to the volume change on forming the magnesium aluminate spinel. The second phase particulates (40) comprising magnesium aluminate spinel are held to such a small size that the second phase particulates (40) impart increased fracture strength while not significantly degrading the IR transmission when compared with untreated sapphire (34). Consequently, precipitation-hardening with magnesium aluminate spinel improves the compressive strength of sapphire (34) while retaining high thermal conductivity and IR transmission.
