Title: Air purging circulator
Inventor: RUHNKE JOHN
IPC: F24D19/08
Filed: 1998-04-14
Abstract: An air purging circulator is provided with a reservoir on the suction side of an impeller chamber in a circulation pump, to allow circulating water to reduce its velocity, and remove air from the lowest pressure point in the system, the suction side of the circulator, where the least amount of dissolved air is present in the circulating water, so that entrained air in the water is released, and vented from the system. The flanged inlet and outlet apertures of the pump housing are axially aligned, and preferably are located at one end of the pump housing opposite from the motor, to allow convenient installation in retrofit of existing systems.      Separation media, such as marbles, wire mesh, or crumpled wire, to further slow the water flow and enhance separation of the air from the water, can be provided in the reservoir.

Title: Imaging a lithographic printing plate
Inventor: FROMSON HOWARD A
IPC: G03F1/00
Filed: 1996-12-05
Abstract: A substrate is coated with a first material which is soluble in a first solvent, whereupon a second material which is strongly adherent to the first material and insoluble in the first solvent is selectively applied by an ink jet printer. The substrate is then developed in the first solvent to establish the image. In a preferred embodiment the substrate is hydrophilic, the first material is a negative working photosensitive material, and the second material is a transparent adhesive, which permits curing the first material by exposure to actinic light after the development step. The adhesive is then removed. In an embodiment directed to a waterless plate the substrate includes a surface coating of silicone, and the first material is a primer which promotes adhesion of a second material in the form of an oleophilic adhesive which is selectively applied. The primer is then developed to expose the silicone on the non-image areas. The ink carrying image areas are formed by the adhesive, which in this embodiment is not removed.

Title: X-ray fluorescence measuring system making use of polarized excitation radiation, and x-ray tube
Inventor: SIPIL HEIKKI
IPC: G21K1/00
Filed: 1998-06-24
Abstract: The invention relates to X-ray fluorescence measuring systems, more specifically to methods for producing polarized X-radiation. The invention is based on the idea of using beryllium as the anode material despite its poor effectiveness. Some of the X- radiation spectrum produced by a beryllium anode is polarized radiation, morespecifically its high-energy portion. The system of the invention involves filtering out the low-energy portion of the spectrum, whereby the remaining intensely polarized radiation can be used as excitation radiation in X-ray fluorescence measurements. The system of the invention is capable of achieving a certain intensity of polarized X- radiation by means of an X-ray tube less powerful than those used in common prior art solutions based on the use of scattering media.

Abstract: A network system which has an exact measure for solving a defect and therefore is very reliable and a method for setting a path thereof. With a plurality of node devices, each of which has a local communication device that is a source of data, an ATM-method loop-type network is built. In the case that a local communication device (21-1) and a local communication device (21-2) transmit data interactively, a communication path (41) for transmitting data and a communication path (42) for receiving data are formed by separate paths at both sides of a loop, and a spare communication path (43) is formed in the reverse direction, When any fault occurs on the transmission path, a loopback is conducted between the node devices which are adjacent to the fault point using the spare communication path to recover the communication path.

Title: In situ method for metalizing a semiconductor catalyst
Inventor: GRAYFER ANATOLY
IPC: B01D53/88
Filed: 1997-04-30
Abstract: A semiconductor catalyst is metalized in situ on a reaction support surface by illuminating at least a portion of the catalyst in the presence of a suitable source of metal to selectively deposit the metal on the illuminated portions.  The source of metal can be applied to the reaction support surface either with the catalyst or separately, but is not attached to the catalyst until the structure is illuminated. This causes the metal to be deposited where the catalyst will be illuminated during use and therefore where photopromoted catalytic degradation can occur.

Patent CA-2258367-A1 (CA)
Title: Bifold head gate assembly and mechanism
Inventor: REQUATE JOHN
IPC: A01K1/06
Filed: 1999-01-05
Abstract: In the agricultural industry, and more specifically the livestock industry, there are times when restraint of the animal is required, whether for administering medication or for physical inspection. It is imperative to both the animal and the handlers that this procedure be conducted with the minimum amount of stress an the animal. This stress includes both mental and physical. Given these stressed conditions, simple situations can become fatal for the panic stricken animal.   In conventional head gate assemblies, many problems exist that either place the animal in mortal danger, or increase the stress level in the animal so as to create further problems, thus endangering both the animal and the handlers.   The patent applicatian outlined herein presents a novel and ingenious solution to problems commonly encountered with current head gate assemblies. In employing a bifold head gate mechanism in where the gate comes laterally from the side of the animal while maintaining its geometric relationship to the animal and the assembly, significant improvements are realized. Furthermore, with a positive self-locking mechanism, once the animal is secured it can be maintained in the head gate assembly indefinitely. This restraint system additionally allows for panels to be created in the head gate assembly so as to present greater access to the neck area of the animal while providing maximum safety for the personnel.   Of serious consideration is the ability of the handlers to reduce the stress placed on the animal. This form of animal ergonomics is realized by the ability of the handlers to operate the head gate assembly from a multiplicity of locations from front to side to rear. This multiple operating location reduces the stress experienced by the animal, thereby increasing the safety of the animal while in he head gate, and too the safety of the handlers. The improvements herein described make the bifold head gate assembly considerably more favourable to all involved in restraining animals.

Abstract: La présente invention concerne un capteur, de type optique et non invasif, qui utilise le signal du mouvement pour calculer la caractéristique physiologique à mesurer. Dans le cas de l'oxymétrie pulsée, on applique au signal du mouvement lui-même une technique des plus petits carrés ou une technique de rapport de rapports. Cela est possible en choisissant un site sur le patient où les variations de mouvement produisent des signaux de deux longueurs d'ondes qui sont suffisamment corrélées. En particulier, on a trouvé qu'un capteur placé sur un ongle, notamment l'ongle du pouce, a pour caractéristique de présenter des signaux du rouge et de l'infrarouge en corrélation lorsqu'on utilise ce capteur pour l'oxymétrie pulsée, et qu'en plus, les signaux résultants sont en corrélation avec la saturation artérielle en oxygène.

Title: Spherical inertial electrostatic confinement device as a tunable x-ray source
Inventor: MILEY GEORGE H
IPC: G21G1/10
Filed: 1997-10-31
Abstract: A low cost small-scale tunable X-ray source, comprising a spherical-electron injected inertial electrostatic confinement (IEC) device. Within a spherical containment vessel (402) recirculatory focusing electrons are accelerated by a spherical grid (401) within the vessel, and cause electron-electron collisions in a dense, central plasma core region (404) of the sphere. The IEC  synchrotron source (IEC-SS) in a mechanism for generating tunable X-ray radiation is essentially equivalent to that for conventional synchrotron sources. The IEC-SS operates at a much lower electron energy (< 100 kev compared with > 200 Mev in a synchrotron), but still gives the same X-ray energy due to the small-scale bending radius associated with the electron-electron interactions. The X-rays can be filtered for particular purposes using diffraction gratings, prisms or the like.
