Filed: 1996-06-07
Granted: 2007-03-13
Abstract: A method of radiolabeling a peptide, e.g., somatostatin or an analogue thereof or vasoactive intestinal peptide, with a radioisotope of technetium or rhenium, comprises the steps of: (a) reacting the peptide with an acetyl-protected t-thiol-containing, amine-reactive bifunctional chelating agent; (b) deprotecting the acetyl-t-thiol group to generate a free t-thiol group; and either (c) admixing the peptide-t-thiol-containing conjugate with a stannous salt; and (d) reacting the mixture of step (c) with pertechnetate or perrhenate, or (c') adding reduced pertechnetate or perrhenate to said peptide-t-thiol-containing conjugate, thereby forming a radiolabeled peptide. Kits for effecting the radiolabeling method, and methods of tumor detection/imaging or therapy are provided.

Abstract: L'invention concerne un système et un procédé de distribution de carburant (14), avec identification des clients en radiofréquence. Le principe consiste à déterminer si un répondeur (23, 25) renfermant les données qui identifient les clients se trouvent dans la gamme d'un distributeur (14) destiné à être activé par le client à des fins de transaction; un dispositif de lecture associé (20) transmet des signaux en radiofréquence et reçoit les données qui identifient les clients en provenance du répondeur (23, 25) lorsque celui-ci réagit aux signaux émis. Une fois le répondeur (23, 25) dans la gamme du distributeur, le client reçoit l'avis correspondant. Dès que le distributeur (14) est activé suite à la confirmation que le répondeur (23, 25) est bien dans la gamme, les données d'identification du client reçues par le dispositif de lecture (20) sont associées à une transaction au niveau du distributeur qui a été activé.

Abstract: An inflatable packer is disclosed involving an expandable mandrel. The mandrel is initially corrugated, creating spaces for a material which can be pushed against an inflatable element when the corrugated mandrel is expanded. The mandrel can be expanded by use of fluid or mechanical forces. The mandrel can be configured to facilitate progressive expansion.  Different fluids can be used to facilitate a permanent set using a hardenable material in the annular space between the mandrel and the element. Different materials can be used so that when subjected under pressure as the mandrel is expanded, they contact each other to form a hardenable filler material. A relief mechanism is provided to allow escape of excess inflation medium in certain circumstances. The yield strength of the mandrel material can vary along its length to facilitate progressive inflation. In certain applications, the inflatable described can also expand the casing in which it is mounted. Those and other features are better understood by a review of the detailed description of the preferred embodiment below.

Abstract: An inert gas bubble-actuated molten metal pump (PU) is located between one section of a metal-melting furnace (10) and a second section to pump molten metal from the one section, wherein the molten metal is at a higher temperature, into the second section, wherein the molten metal (26) is at a lower temperature, and its effluent is directed into contact with metal chips (80) being charged into the second section, thereby assisting in the more rapid melting of the chips into the molten metal (26) mass in the second section. The inert gas (IG) employed to actuate the molten metal pump (PU) is captured beneath a heat-resistant and flame-resistant cover (30) located above the exit port of the pump (PU) and over a substantial portion of the molten (26) mass in the second section, thereby providing a non-oxidizing atmosphere at the surface of the molten metal (26) mass or pool beneath said cover (30). In this manner the inert gas (IG) is employed not only to actuate the inert gas bubble-actuated molten metal pump (PU), but also to assist in the rapid melting of metal chips (80) being charged, as well as to provide a non-oxidizing atmosphere at the surface of the molten metal (26).

Title: An lpi digital receiver
Inventor: LEE JIM P Y
IPC: G01S3/46
Filed: 1999-07-27
Granted: 2005-10-25
Abstract: A pulse Low Probability of Intercept (LPI) signal discriminator has a soft-limiting IF amplifier chain for receiving an IF signal to soft-limit any high-peak IF signals in the IF signal and a high-peak amplitude compressive circuit followed by an integrator which integrates the signal over a predetermined time to produce a high output when a LPI signal is present. The integrator is connected to a threshold detector which outputs a trigger signal when a high output from the integrator is received. In a receiver having a plurality of channels for received signals from a number of antenna, one channel for each antenna, the received signals are down converted to IF signals and applied to analog-to-digital converters (ADCs) which are connected to a digital processor. A pulse/LPI signal discriminator is connected to a channel to receive an IF signal from an associated down converter and produce a trigger pulse when a LPI signal is present which will gate signals from buffer memories connected to ADCs to the digital processor if an LPI signal is detected.

Title: Ship or barge based compressed gas transport system
Inventor: FITZPATRICK P JOHN
IPC: B63B25/14
Filed: 1999-09-22
Granted: 2007-09-04
Abstract: A marine gas storage and transport system formed of small diameter steel pipe, which is stacked horizontally in a hexagonal pattern. The system is suitable for use on top of a barge or inside the holds of a ship. The horizontal hexagonal stacking and the use of small diameter pipe permit large stacking heights to be reached without over- stressing the pipes at the bottom of the stack. The pipes are laid down in long straight lengths and are manifolded in groups of two (2) and seven (7) at their ends by a unique system that space-wise still permits the hexagonal stacking arrangement and also allows for about 33% (thirty three percent) of the system to be continuously inspected by a pig. Each group of seven can be connected to another group of seven and so also can the groups of two. Thus very large volume storage units can be constructed cheaply and efficiently. In addition when the pipes are stored within the holds of an ocean going ship a transverse watertight bulkhead is created approximately every 20 to 50 meters by infilling the spaces between the pipes with a watertight material. Since the spaces are small the force from the water head is low and the required longitudinal water-tightness can be provided by a number of materials ranging from silicone to epoxy products. This is a unique component of the invention as it precludes the expensive necessity of providing multiple penetrations through a standard watertight bulkhead.

Abstract: An apparatus and method of forwarding a first message from a source to a destination via a link state routing network utilizes point-to-point feedback messages when the quality of a first path from the source to the destination meets some prescribed condition. To that end, the first path is initialized within the link state routing network. A feedback message having data relating to a quality of the first path then is received as a point-to-point message that is forwarded to the source. In response to receipt of the feedback message, a second path is initialized from the source to the destination. The first message then is forwarded to the destination via the second path.
