Abstract: An electrical connector includes a dielectric housing that holds pairs of signal modules adjacent one another. Each signal module includes a mating edge having a row of mating contacts, a mounting edge having a row of mounting contacts, and a plurality of conductors electrically connecting each mating contact with a respective mounting contact. The mating contacts in adjacent modules have a first contact spacing therebetween, and the mounting contacts in adjacent modules have a second spacing therebetween. The conductors in adjacent modules have a third spacing therebetween. The second and third spacings are selected to provide a pre-determined impedance through the signal modules.

Abstract: A process for producing alumina from bauxite is described in which bauxite is treated with an alkali to form a mixture comprising a solution of aluminum-containing ions and alumina trihydrate is precipitated from the solution. The process comprises treatment of the solution before or after the precipitation step with a layered double hydroxide in order to remove impurities from the solution by intercalation into the layers in the double hydroxide. The double hydroxide may contain layers of the formula: [LiAl2(OH)6]+.

Abstract: A stacked jack multi-port shielded and magnetically conditioned connector assembly is provided for assembly in three distinct configurations. In one configuration where power over ethernet is not required, the connector assembly has modular jack terminals which are directly connected to a motherboard. In a second configuration, the connector assembly can receive conditioned and controlled electrical signals to the connector, whereby power over ethernet may be provided through designated ones of the modular jack terminals. In a third configuration, the connector assembly is configured for an integrated power over ethernet card, whereby the device is provided as an integrated assembly.

Abstract: A cable connector assembly includes a ferrule assembly configured for attachment to a cable braid, and a resilient contact element surrounding an end of the ferrule assembly. A retaining band clamps the cable braid to the ferrule assembly. A conductive shell is configured to compress the resilient contact element.

Abstract: An electrical connector is provided that includes a housing having a mating interface. Contacts provided in the housing are organized in differential pairs with the contacts in each of the differential pairs being located along an associated differential pair contact line. The differential pairs are aligned wherein the differential pair contact lines of adjacent differential pairs are non-parallel to one another.

Abstract: A stacked jack multi-port shielded and magnetically conditioned connector assembly is provided having a multi-port electrical connector housing having a plurality of housing ports adjacent a mating face thereof. A shield member comprises a base shield portion and sidewall portions extending from side edges of the base shield portion. The sidewall portions extend in opposite directions from the base shield portion. A plurality of modular connector subassemblies are adapted for stacking with the base shield portion positioned therebetween, and with one of the shield sidewall portions positioned against a side of one of the housings and the other shield sidewall portion is positioned against a side of the other housing.

Abstract: A stacked jack multi-port shielded and magnetically conditioned connector assembly is provided for assembly in three distinct configurations. One configuration is where power over ethernet is not required, but rather modular jack contacts are directly connected to a motherboard. A second configuration, the connector assembly can be configured to be enabled to receive conditioned and controlled electrical signals to the connector, whereby power over ethernet may be provided through designated ones of the modular jack contacts. Alternatively, the connector can be configured for an integrated power over ethernet card, where the device is provided as an integrated assembly.

Abstract: A high speed signal connector having a plurality of signal conductors disposed within the housing and a ground bus or plane disposed within the housing and including a plurality of coextensive layers of different conductive materials including at least a first conductive base layer having predetermined conductivity and permeability and a second conductive top layer have predetermined conductivity and permeability. A multiple layer common ground provides for improved current flow within the common ground so as to minimize cross talk between signal contacts. As a result, the present invention provides a connector for high frequency signal transmission which exhibits an attenuation characteristic which is substantially independent of frequency within a predetermined and selectable frequency range and which permits the tailoring of the attenuation and phase response of the connector as a function of frequency.

Abstract: A process for separating a compound from a mixture of different compounds is disclosed for compounds comprising at least two negatively charged groups connected by a linker group. The process comprises treating the mixture with a material comprising layers containing at least two different types of cation disposed in an ordered arrangement within each layer, such as layers of formula LiAl2(OH)6+, in order to separate the compound from the mixture by selective intercalation of the compound into the material.
