Title: Fluid purification
Inventor: BUTTERS BRIAN E
IPC: C02F1/72
Filed: 1996-02-22
Granted: 2007-01-30
Abstract: The present invention relates to a method for the purification of contaminated fluids by photocatalytic treatment. In accordance with the invention, an oxidation state where contaminant molecules are oxidized and/or a reduction state where contaminant molecules are reduced are employed to purify a contaminated fluid. The reduction state, where certain contaminant molecules are reduced, is induced by providing a reactant, such as citric acid, in the presence of an excited photocatalyst. A reduction state may alternate to an oxidation state, where contaminant molecules are oxidized, by the addition of an oxidizing agent, such as oxygen.

Title: Semiconductor modulator with a shift
Inventor: YU JUN
IPC: G02F1/015
Filed: 1996-05-08
Granted: 1999-08-24
Abstract: A MQW semiconductor Mach Zehnder phase modulator is formed by two Y-junctions (12, 32), each having a single waveguide (14) optically coupled with two branch waveguides (18, 20). The branch waveguides of the two Y-juntions are optically coupled in Mach-Zehnder configuration that, under zero bias conditions, has one interferometric arm longer than the other to provide a .pi. phase shift. The additional length is preferably accommodated in the branches of the Y-junctions. The phase shift, in combination with voltage dependent absorption properties and non-linear phase variations of the MQW guided regions in the Mach-Zehnder modulator results in a negative chirp and high extinction ratio for an equal, push-pull device configuration.

Granted: 2004-08-03
Abstract: A unitary resilient expansion joint insert member is provided for insertion into the expansion joint between adjacent concrete floor slabs. Such member is of substantially-constant transverse cross-section for filling an expansion joint gap which is formed between adjacent concrete flooring slabs. The insert member consists essentially of a cap portion having a convexly curved upper surface and a concavely curved lower surface.  The lower surface of the cap portion forms a substantially-planar surface, which is generally parallel, and adjacent, to the surface of the adjacent concrete slabs, when the insert member is arranged in the expansion joint. A projection portion which is integral with the cap portion extends downwardly from the lower surface of the cap portion to a lower end.  The projection member consists of parallel, planar opposed walls extending perpendicularly to the lower surface of the cap and an anchor portion having a pair of horizontal planar surfaces. Each horizontal surface extends perpendicularly to and in opposite directions from, the walls, to respective outer edges. The anchor portion also has planar angle surfaces extending respectively from the outer edges of the horizontal surfaces to a common point at the lower end of the projection members. The walls and the anchor portion have the shape of an arrow. The resilience of the cap portion provides a slight upward force on the projection member to exert a positive, engaging force that tends to lock the projection member in the gap.

Title: Process and apparatus for gas phase exothermic reactions
Inventor: CHAOUKI JAMAL
IPC: F23G7/07
Filed: 1996-12-10
Granted: 2002-01-29
Abstract: The gas phase exothermic reaction of a feed gas mixture  is carried out by providing  first  and second chambers in fluid communication with one another and each containing a bed of solid heat exchange material and at least one bed of catalyst material,  each chamber being selectively operable in cooling and heating modes.  The feed gas mixture is introduced into a selected one of the chambers when the selected chamber is in the cooling mode and the other chamber is in the heating mode so that the feed gas mixture  flowing through the  selected chamber contacts  the  bed  of  heat  exchange  material  before contacting the bed of catalyst material,  the  feed gas mixture being  reacted  in the  catalyst  bed  to  form a gaseous product.  The gaseous product is conducted from the selected chamber to the other chamber so that the gaseous  product  flowing  through  the  other  chamber contacts the bed of catalyst material before contacting the bed of heat exchange material. The direction of gas flow through the  chambers  is periodically reversed so that the first and second chambers alternately operate in the cooling and heating modes,  thereby forming between the first and second chambers a hot zone containing the gaseous products. A portion of the gaseous product is discharged from the hot zone so as to withdraw sufficient heat to maintain the reaction in the catalyst bed of the selected chamber at a temperature below a predetermined maximum temperature, while maintaining autothermicity.

Title: Anti-tamper integrated circuit
Inventor: CANDELORE BRANT
IPC: G06F21/00
Filed: 1998-02-20
Granted: 2005-05-03
Abstract: An anti-tamper integrated circuit (IC) apparatus is adapted for use with an IC that carries an active component, such as a secure processor, which requires a constant power signal to operate.      If the power signal is interrupted, data is erased from a volatile memory of the secure processor. The memory is located within the IC package. An external power signal is coupled to the memory via a conductive path which is carried outside the housing and which may be embedded in a decoder board, micro-module substrate, or smart card body in which the IC is carried. The conductive path may carry the power signal directly to the memory, or it may carry the power signal to bias a transistor. Removal of the IC package from the decoder board, micro-module substrate or smart card, will open the conductive path and interrupt the power signal to the memory by causing a short circuit or an open circuit. As a result, the data stored in the memory will be lost.      The apparatus therefore deters a pirate from tampering with the IC.
