Title: Weight-supported adjustable mixing and dispensing gun for two chemically reactive materials
Inventor: FRAZIER RICHARD L
IPC: B05B15/06
Filed: 1997-10-23
Abstract: A mixing and dispensing system for two reactive fluids, such as two-component polysulfide sealants, in which the dispensed fluids are supplied to a hand operated mixing and dispensing gun through a pair of flexible hoses suspended above the floor from a pivotal boom. The flexible hoses are pivotally attached with swivel joints onto the inlets of the gun that are spaced on opposite lateral sides of the gun, and the swivels are rotatable about a common generally horizontal pivot axis. The gun is fully weight supported in an operative position above the floor with a tool balancer attached to the boom. The tool balancer includes an adjustably tensioned and extendable line that is pivotally attached to the top of the gun body and rotatable about a generally vertical pivot axis. The gun passes the two reactive fluids separately through the gun body and mounted on the divided outlet of the gun is a disposable static mixer having a single inlet attached to an elongated spiral mixer tube that terminates in a dispensing outlet nozzle. A hand operated actuating trigger is mounted on the static mixer tube in close proximity to the dispensing outlet nozzle. The mixing and dispensing gun is lighter, generates less waste, and is more maneuverable than prior two component mixing and dispensing guns.

Patent CA-2221308-A1 (CA)
Title: Multi-gigahertz frequency-modulated vertical-cavity surface emitting laser
Inventor: MORGAN ROBERT A
IPC: H01S5/42
Filed: 1996-05-28
Abstract: A GHz-range frequency-modulated laser based on manufacturable vertical cavity surface emitting lasers (VCSELs) and arrays. The present invention exploits a saturable absorber contained within the VCSELs distributed Bragg reflector which may itself be adjusted during fabrication or in operation. Under controllable operating conditions, the saturable absorber, strategically sized and placed, will force the VCSEL to self-pulsate (in the GHz-regime) at rates related to the local intensity, absorption, lifetime, and carrier density of the saturable absorber. These conditions can be controlled in real time in one of three ways; first, by adjusting the injection current into the VCSEL itself; second, for a fixed VCSEL bias and the use of a third terminal, by modifying the carrier density within the saturable absorber via additional current injection; or third, the saturable absorber can be reverse-biased by simultaneously altering its absorption and carrier lifetime and thus carrier density. Additionally, the frequency response can be controlled in the fabrication process by affecting the location of the saturable absorber, the mirror design and cavity Q, and the laser size (and hence threshold current). One can easily multiplex numerous GHz channels into a 100 plus GHz transmitter in a cost-effective manner. Application of the saturable absorber for selfpulsation provides for a decoherence of the VCSEL light output to eliminate modal noise in data communication systems, or for use as a local oscillator in an RF or other system. A plurality of VCSELs may be formed into an array having various frequencies, intensities, phases or other properties. The VCSELs may form a phased array, for instance.

Title: Use of il-13 to induce 15-lipoxygenase
Inventor: LAKKIS FADI G
IPC: A61K38/00
Filed: 1996-05-13
Abstract: The present invention is based on the discovery that IL-13 induces 15-LO in human monocytes. Surprisingly, it has been found that IL-13 is about ten-fold more active, on a molar basis, than IL-4 in inducing 15-LO. IL-13 is therefore an effective therapeutic for inflammatory conditions responsive to products of 15-LO activity, including 15-S-HETE and LXA4. By enhancing endogenous pathways leading to synthesis of endogenous anti-inflammatory molecules, administration of IL-13 results in inhibition of the end effectors of the inflammatory process itself. The underlying strategy is therefore to direct intervention to specific pathogenic molecules, rather than the current method of treating symptoms of inflammation.
Patent CA-2223380-A1 (CA)
Inventor: ILENDA CASMIR STANISLAUS
IPC: B29C48/16
Filed: 1997-12-03
Abstract: Acrylic light pipe has adequate thermal and photo-thermal stability for many purposes, but is deficient in maintaining clarity, color, and good optical properties under conditions of exposure to high temperatures, especially in combination with exposure for lengthy periods to passage of light. Improved thermal stability, as reflected in reduced color formation, can be imparted by adjusting the polymerization conditions to produce the uncured core polymer of the core/clad construction with a much reduced terminal vinyl content, preferably below 0.5 vinyl groups/ 1000 monomer units. This process improvement, in combination with selected addition of a combination of certain hindered phenols and hydrolytically stable organic phosphites, together produce a substantial improvement in the resistance to discoloration under photo-thermal conditions, while maintaining the resistance to discoloration under thermal conditions. The known process conditions which do not yield lower terminal vinyl content, in combination with the selected additives, also produceacrylic light pipe with greatly improved photo-thermal stability.

Title: Procede servant a mesurer des profondeurs d'eau relativement limitees particulierement au voisinage du littoral et de bords de lacs
Inventor: JOHANSSON KENNETH
IPC: G01S17/08
Filed: 1996-08-07
Abstract: L'invention concerne un procédé servant à mesurer des profondeurs d'eau relativement limitées. On utilise des instruments de mesure afin d'émettre, dans un sens orienté selon un petit angle .alpha. par rapport à la perpendiculaire de la profondeur de l'eau, et de recevoir des impulsions laser de ? = 0,5 µm environ. On obtient une première réflexion depuis la surface de l'eau et une deuxième réflexion depuis le fond. La profondeur de l'eau est calculée par traitement des signaux correspondant aux réflexions. Ce procédé est caractérisé par le fait que le traitement de signaux s'effectue de telle façon que la fonction amplitude/temps du signal est explorée et qu'une première ligne sensiblement droite constitue une approximation d'une première partie de cette fonction, puis cette fonction est de nouveau explorée, de façon à passer par un minimum de sa première dérivée (point d'inflexion) pour rejoindre une deuxième partie croissante de la fonction située avant un point maximum dont une deuxième ligne sensiblement droite constitue une approximation, après quoi l'intervalle temporel entre les lignes relatif à ladite distance, est utilisé pour la détermination de cette dernière.

Title: Measuring of pain
Inventor: LASEROW KAY
IPC: A61B5/103
Filed: 1996-12-18
Abstract: The invention relates to a measuring instrument for the measurement of an existing pain or a feeling of nausea of a patient. The measuring instrument induces pain in an arbitrary body part of said patient, by supplying an electrical current. The measuring instrument provides a current increase into said body part, until said induced pain is experienced by the patient as being as great as the existing pain/nausea. The current is supplied from a current source arranged in the measuring instrument via wires (H, I) and electrodes (C, D), said electrodes being applied onto that part of the body in which pain is to be induced. When the pain induced is experienced to be as great as the existing pain/nausea, the body part is removed from the electrodes, whereupon a pain value is registered and shown on a display (F).

Title: A rack for drying pasta
Inventor: MCKINNON ROBERT
IPC: F26B25/18
Filed: 1998-07-27
Abstract: A rack for drying pasta normally has drying dowels affixed to a post or framework. In this invention, the dowels are not attached to the rack and are mounted only when drying pasta.     This invention relates to the easy handling and drying of home-made pasta. It is common for pasta drying racks to have the drying dowels affixed to the rack.  It is therefore necessary to transfer pasta from the pasta forming machine to these dowels and later to the cooking pot. Storage of these racks is difficult as they must be folded, if possible, and the dowels are left exposed to contamination and damage.      I have found that these disadvantages can be overcome by having the drying dowels not affixed to the rack. This allows the pasta to be picked up on a dowel as it emerges from the pasta machine and transferred to the drying rack. When ready to cook, the pasta is carried on the dowels to the cooking pot. The drying rack has a built in storage compartment for the drying dowels and is compact for easy storage. It can be hung on a wall while not in use or even when drying pasta to save counter space.
