Patent CA-2170640-A1 (CA)
Inventor: DECHENE RONALD L
IPC: G01R33/31
Filed: 1994-08-05
Abstract: A pulsed nmr analysis system (figure 1a) for polymer mate-rials (S2) extracted from industrial processes at a mobility enhanc-ing temperature (figure 3) (at or above glass transition temperature for amorphous polymers, at the crystalline transition temperature for crystalline and semi-crystalline polymers). The sample is measured via nmr techniques and results correlated to viscosity and melt in-dex or melt flow (which are related to average molecular weights). Substantial improvement of correlation of nmr derived constants and equations of a free induction decay curve with the foregoing polymer properties is obtained via (1) conducting the nmr process at a mobility enhancing temperature  (normally elevated compared to the industrial process temperature of the industrial process) and (2) holding temper-ature substantially constant at such elevated temperature.

Abstract: A propulsion apparatus having at least one converging duct (1) connected to a diverging duct (2). When the apparatus is in motion,fluid flowing through the converging duct (1) converts a portion of its own mechanical energy into propelling energy, which is the product of the thereby generated thrust and propelling speed, whereas fluid flowing through the diverging duct (2) converts its own heat into mechanical energy, thereby cooling the fluid by the amount of work performed by the thrust.

Abstract: L'invention porte sur un appareil de gestion d'un système de télécommunications basée sur le crédit. L'une de ses variantes comporte une interface (133) fournissant des informations de crédit sur un abonné particulier et recevant des relevés (113) de communications relatifs à ce même abonné qui proviennent d'une centrale de commutation (111) chargée de l'établissement des liaisons entre les différents dispositifs de télécommunications. Un dispositif de limitation de crédit (131) utilise alors lesdites informations de crédit pour déterminer la limite de crédit de l'abonné. Une autre variante comporte un appareil utilisant une demande de validation de préappel associée à l'abonné d'un système de télécommunications qui tente d'établir une communication dans une zone desservie par un système différent (par exemple itinérant) pour détecter une activité potentiellement frauduleuse et notamment une fraude par clonage. Une troisième variante, comporte un dispositif de détection qui utilise une indication temporelle relative à une demande de validation de préappel pour identifier une communication survenant dans une séquence de temps improbable et indiquant la possibilité d'une communication frauduleuse.

Title: Method and apparatus for pouring molten material
Inventor: LUMPPIO JUHA LAURI
IPC: B22D41/04
Filed: 1996-05-08
Abstract: The present invention relates to a method and apparatus for pouring molten material, such as molten metal, into a casting mold so that the amount of melt can be weighed in connection with the pouring. In order to keep the pouring height of the molten material low and its motion as smooth as possible during the pouring step, the bottom of the ladle containing molten material is designed to be essentially curved, with such a radius of curvature that the thickness of the molten layer located in the ladle is, even at its thickest, only a fraction of the length of the radius of curvature of the bottom. The casting method of the invention is advantageously realized by means of a cradle arrangement of the ladle according to the invention.

IPC: H01L23/02
Filed: 1996-05-10
Abstract: A process (20) for repairing leaking glass-to-metal seals (13) of a hybrid micro-circuit header (10). The process (20) comprises the following steps. A leaking hybrid microcircuit header (10) is delidded (21) (has its lid (18) removed). The leaking hybrid microcircuit header (10), generally with its leads (12) pointing vertically, is disposed (22) on a vacuum source (15). A vacuum is formed (23) on the hybrid microcircuitheader (10) using the vacuum source (15). A stream of helium is flowed (24) over the seals (13) to verify the presence of leaks in the seals (13) of the hybrid microcircuit header (10). A small amount of high vacuum sealant (11) is applied (25) to each of the leaking glass-to-metal seals (13) while the hybrid microcircuit header (10) is exposed to the vacuum. The vacuum draws the sealant (11) through the cracked or defective glass-to-metal seals (13). The high vacuum sealant (11) generally comprises a silicone resin having a low vapor pressure. A stream of helium is caused to flow (26) over the resealed leads (12) following application of the high vacuum sealant (11) to confirm that the hybrid microcircuit header (10) is sealed. The hybrid microcircuit header (10) is removed (27) from the vacuum source (15). The hybrid microcircuit header (10) is then cured (28) at a temperature of 15010 degrees Celsius for a minimum of 2 hours to complete the repair process (20). The lid (18) is reattached (seam sealed) following repairs. A final leak test is performed after reattachment of the lid (18).

Patent CA-2179847-A1 (CA)
Inventor: GAGNON ROBERT E
IPC: G01B11/06
Filed: 1996-06-25
Abstract: A method and an apparatus are disclosed for remotely determining the thickness of a transparent or semi-transparent suspended sheet or solid or liquid layer, e.g. ice, on a solid surface which is either light-absorbent or highly reflective. The invention proposes directing a coherent beam of light onto a location on the layer such that the beam undergoes partial reflection from the top of the layer and partial reflection from the bottom of the layer or the underlying surface. Due to the coherency of the beam, two overlapping speckle patterns are produced which give rise to an interference pattern having interference fringes. The pattern can be caused to shift across the field of view and the shift, determined by a number of the passing interference fringes can be interpreted in terms of the thickness of the layer.

Title: Improved ndir gas sensor
Inventor: WONG JACOB Y
IPC: G01N21/35
Filed: 1995-01-30
Abstract: A miniaturized NDIR gas sensor is manufactured using semiconductor micromachining techniques from a semiconductor  material such as SI or GaAS. The NDIR gas sensor (28) includes an optical waveguide (30), a light source (32) at one end of the waveguide, at least one light detector (36) at the end of the waveguide opposite the light source, a diffusion type gas sample chamber (34) formed within the waveguide and interposed in the optical path between the light source and light detector so that the light source and light detector are thermally isolated from the gas sample by windows (38, 39), and a separate bandpass filter (52) interposed between the light source and each light detector. Because the NDIR sensor is fabricated out of a semiconductor material, the source driver (76) and signal processing electronics (78) may be added directly to the sensor using integrated circuit fabrication techniques. Particles and smoke and dust may be kept out of the sample chamber by application of a gas permeable membrane (56) over apertures (54) in the sample chamber walls.

IPC: F16L1/028
Filed: 1995-11-20
Abstract: Disclosed is a method of extracting a hollow unit laid in the ground, such as a lead pipe (2) which is accessible at both its open ends. For this purpose, a flexible tube (14) which can be pressurised from inside is introduced in its unpressurised state into the pipe, then pressurised from inside to force the flexible tube against the inner wall of the pipe, and the pipe is then pulled along its longitudinal axis out of the ground, using the flexible tube, during which procedure the internal flexible tube pressure is maintained and there is no axial movement between flexible tube and pipe. Rupture of the pipe during extraction is thus avoided. A new pipe, which is laid in the ground as the old one is being removed, can be connected to the flexible tube or to the lead pipe being extracted behind the rear end (in relation to the direction of pull) of the lead pipe. An additional traction element (12) can be introduced into the pipe together with the flexible tube; this element is forced against the inner wall of the pipe by the inner pressure of the pressurised flexible tube and used either on its own or with the flexible tube to pull out the pipe.
