Title: Secure distribution and protection of encryption key information
Inventor: NORDENSTAM JAN OLOF
IPC: H04L9/30
Filed: 2000-03-20
Granted: 2010-05-18
Abstract: The invention relates to secure distribution of a private key (K) from a distributing unit (1) to a receiving unit (2), and is based on providing each of the distributing unit and the receiving unit which a protecting circuit holding an original private key unique for the protecting circuit. The protecting circuit (20) of the receiving unit (2) is associated with a certificate (CERT 2) holding information on the type of the protecting circuit. The protecting circuit (10) of the distributing unit requests this certificate to verify the authenticity by using a public key, of a certificate authority, stored in the protecting circuit (10). Next, the protecting circuit (10) determines, based on the type information of the certificate, whether the protecting circuit (20) of the receiving unit represents a type of circuit that is acceptable for protecting the private key (K) to be distributed. If the protecting circuit is found to be acceptable, the private key is encrypted and transmitted thereto. The received key is decrypted and stored in the protecting circuit of the receiving unit. In this manner, the private key is protected during transfer and may be distributed to and securely protected in one or more receiving units.

Title: Method to modulate plant growth by injecting a plug at lift
Inventor: KITCHEN JOHN
IPC: A01G7/00
Filed: 2003-09-12
Granted: 2006-03-07
Abstract: A method for modulating plant growth is provided whereby seedlings that are grown in containers such as blocks are fertilized at lift. Prior to fertilization, the block, which has numerous plug cavities, is restrained. The seedlings, which are grown in plugs formed in plug cavities, are supported and a bore is drilled into the bottom of the plug. The bore extends to the top of the plug to produce a small port, which serves as a port for expulsion of air during the injection operation. The fertilizer is measured in a metering roller and is then pneumatically injected into the bore in the plug. Upon completion of the injection, the bore is closed to reduce the loss of fertilizer from the plug. The various operations may be automated or performed manually.

Title: Apparatus and method for photocatalytic and thermocatalytic pollution control
Inventor: MURADOV NAZIM Z
IPC: B01J21/06
Filed: 1999-04-08
Granted: 2005-07-26
Abstract: A new method for design and scale-up of photocatalytic and thermocatalytic processes is disclosed. The method is based on optimising photoprocess energetics by decoupling of the process energy efficiency from the DRE for target contaminants. The technique is applicable to both low- and high-flux photoreactor design and scale-up. The low-flux method is based on the implementation of natural biopolymeric and ocher low-pressure drop media support for titanium dioxide and other band-gap photocatalysts. The high-flux method is based on the implementation of multifunctional metal oxide aerogels and other media in conjunction with a novel rotating fluidized particle bed reactor.

Granted: 2011-07-26
Abstract: A method and apparatus for anaerobic treatment of organic wastes in a liquid filled vessel (10) wherein particles of the waste are buoyed and form a floating bed in the liquid by the gasses generated by the anaerobic digestion of the wastes. The bed forms to an upper stratum of the least digested, least dense waste and a lower stratum of the most digested, most dense waste. Liquid from beneath the bed is continuously sprayed over the upper surface of the bed through a series of discharge ports (40A, 40B, 40C) which expands to bed downwardly. Each spraying period is followed by a quiescent period to allow the bed to reform. Over time the floating bed is moved from an inlet end to an outlet end of the vessel (10) where the most digested waste is removed.

Abstract: L'invention concerne l'utilisation éventuelle d'un puits de congélation pour isoler un sol voué à la réhabilitation, l'objectif étant de former une barrière de congélation autour de la zone du sol traitée. Ladite barrière peut empêcher l'entrée de fluide dans la zone traitée, empêcher la migration des contaminants hors de la zone traitée, et ceinturer entièrement le périmètre de cette zone. On peut aussi établir une barrière de congélation au-dessus ou au-dessous de la zone traitée. L'activation d'un puits de congélation peut être une étape préalable à la réhabilitation du sol, permettant de disposer d'une barrière de congélation lorsque la réhabilitation débute. La réhabilitation peut être conduite selon un système quelconque, y compris la réhabilitation thermique. Les installations chauffantes utilisées dans le cadre d'un système de réhabilitation thermique peuvent être proches de la barrière de congélation, sans risque de rupture de la barrière au cours de la réhabilitation.

Abstract: L'invention concerne la formation de groupes (2) d'objets plats (11 à 14) amenés en une pluralité de flux d'alimentation (1.1 à 1.4). Selon l'invention, ces flux d'alimentation (1.1 à 1.4) sont regroupés en un seul flux ; une pluralité de flux lamellés, dont les lamelles sont équidistantes, sont superposés ; les zones périphériques de tête des objets (11 à 14) des flux lamellés superposés sont orientées dans le sens d'acheminement ; des groupes (2) d'objets (11 à 14) sont séparés du bout terminal du flux regroupé par serrage et accélération des zones périphériques de tête superposées. Les flux d'alimentation (1.1 à 1.4) sont alors superposés en au moins un emplacement de regroupement, les objets (11 à 14) étant mutuellement parallèles et orientés transversalement relativement au sens d'acheminement dans tous les flux superposés à regrouper, et lesdits objets ayant le même écartement mutuel et se déplaçant à la même vitesse. Des projections des flux (1.1 à 1.4) superposés à regrouper sont mutuellement parallèles et coïncident sur un plan parallèle à l'orientation parallèle des objets (11 à 14). Des projections des flux (1.1 à 1.4) à regrouper convergent de manière tangentielle sur un plan transversal à l'orientation parallèle des objets (11 à 14). Les flux (1.1 à 1.4) à regrouper sont synchronisés de sorte que, lors de la superposition des flux, les zones périphériques de tête des objets (11 à 14) sont sensiblement superposées.

Granted: 2010-09-21
Abstract: A light pipe may be used to illuminate an elongated area. Light may emanate laterally relative to the axis of the light pipe, and the light intensity is substantially uniform along the length of the light pipe. The light pipe may include a translucent member and a opaque reflective member that is separated from the translucent member by an air gap. A band of reflective material may be located on an exterior surface of the translucent member. The entire light pipe may be formed by co-extrusion of the translucent member, the band of reflective material and the opaque section through a single co-extrusion die. Light emitted laterally from the translucent member toward the arcuate opaque reflective member and band of reflective material may be reflected laterally through the translucent member transverse to the axis of the light pipe, so that all light extends through the front surface of the translucent member.

Abstract: An electrical terminal (100) and a housing (52) are sufficiently stiff to prevent arcing and physical damage to the electrical terminal upon being exposed to surge current/voltage. The terminal includes a base portion (112) from which two spaced apart arms (114 and 116) extend outwardly. First portions of the arms (118 and 120) are generally parallel to one another.  Second portions of the arms (122 and 124) converge toward each other and then flare outwardly along third portions of the arms (126 and 128). There is a contact region (130) formed at the junction of the second and third portions;  the contact region receives a lead of a surge protection device (70 and 72).  The terminal is enclosed in an opening (80) in the housing (52); the opening being bordered by walls (84, 86, 88 and 90) closely adjacent (0.001 inches) to the first portions of the arms. When the terminal is exposed to a surge current/voltage, the walls stiffen the terminal and prevent arcing and physical damage.
