Patent CA-2273056-A1 (CA)
Inventor: SHANTHIKUMAR SATHURUKULASINGAM
IPC: H05B41/282
Filed: 1999-05-27
Abstract: Usually solar lamps consist of a lamp with a 6 Volt or 12 Volt rechargeable battery and a 6V or 12V bulb. The solar lamp is charged by a solar panel which produces electricity on exposure to sunlight and charges the 6V or 12V rechargeable battery during the day time. At night, the charged battery operates a 6V or 12V bulb in the lamp, producing light.       In this invention called the "Portable Jaffna Solar Lamp", a 15 watt solar panel, on exposure to sunlight, produces electricity and electrically charges a completely sealed, maintenance-free, rechargeable, 12 Volt 17 Ampere Hour Lead acid battery (battery capacity can range from 17 to 20 Ampere Hours). But unlike in other models of solar lamps and 12V lights, here, the 12 Volt current is fed to a standard 350 watt inverter (the inverter may range in capacity from 250 to 350 watts) which produces 110 Volt current from the 12Volt current. The 110 Volt current is now fed to a 110 Volt 23 watt Compact Fluorescent bulb to produce light. The very low (watt) energy consumed by this particular type of bulb makes it possible to have an excellent portable lamp with a very high light output of 1580 lumens, giving light for 5 to b hours in remote areas, on camping trips or in emergencies. Instead of using a solar panel to charge the "solar lamp", one could also use the cigarette lighter socket of an automobile or other 12V source. The Portable Jaffna Solar Lamp is so designed that on exposure of the 15 watt solar panel to about 8-10 hours of sunlight, the lamp can provide portable light for about 5 to 6 hours at night. A charge controller may be used to connect the solar panel to the lamp where necessary (according to the size of the solar panel used).

Filed: 1997-10-30
Abstract: La présente invention concerne un procédé et un dispositif de production d'azote comprimé par turboséparation à basse température dans un système de rectification présentant un colonne de pression (4) et une colonne basse pression (5). L'air d'utilisation (1, 3) est introduit dans la colonne de pression (4). Une fraction (11) liquide à teneur en oxygène est prélevée de la colonne de pression (4) et introduite dans la colonne basse pression (5). L'azote gazeux (18) provenant de la colonne basse pression (5) est condensé, du moins partiellement, dans un condensateur de tête (17) par échange indirect de chaleur à l'aide d'un liquide d'évaporation (13). Pour obtenir l'azote de la colonne de pression sous forme comprimée en phase gazeuse (24, 25, 29), on utilise une pression supérieure à celle requise pour le fonctionnement de la colonne basse pression (5). L'azote (20) liquide prélevé de la colonne basse pression est exposé en l'état à une pression supérieure à celle de la colonne basse pression (5). Le liquide (22) mis sous pression est mis à évaporer dans un évaporateur (23) par échange indirect de chaleur avec un support thermique (35), ce qui donne un produit d'azote comprimé (24, 25, 29) en phase gazeuse.

Title: Improved missile warhead design
Inventor: BOOTES THOMAS H
IPC: F42B12/20
Filed: 1998-12-03
Abstract: The need in the art is addressed by the hard-target penetrating warhead of the present invention. In the illustrative embodiment, the inventive system is adapted for use with length constrained missile payload bays and includes a warhead case for containing explosives. A tungsten ballast is inserted within the case to provide a high warhead sectional pressure upon impact of the missile against a target. A fuse detonates the warhead explosives following penetration of the target. A fuse well houses the fuse and is attached to the case at one end. A slip fit section of the fuse well provides structural support to the case and prevents dislodging of the fuse well and the fuse from the case upon missile target impact. Explosives blowout ports included in the fusc well inhibit undesirable detonation of the warhead explosives by accidental exposure to high heat. In a specific embodiment, the case includes a 6 caliber radius head nose. The fuse well includes main explosives blowout ports for allowing accidental exposure to high heat to burn the missile explosives and safely vent gases resulting from the burning. The main explosives blowout ports are placed around a circumference of the fuse well and include nine ports having a surface area designed to prevent undesirable detonation. The blowout ports also include booster blowout ports for allowing safe venting of booster charge explosives that are included in the fuse. Additionally, a special polyethelene/polyalphaolefin liner lines the inside of the case for improving safe venting performance under fast cook-off hazardous conditions.  The warhead explosives include PBXN - 109. The case includes a textured or lightly grooved surface for facilitating bonding of the ballast to the case.

IPC: C12Q1/68
Filed: 1998-03-20
Abstract: The APC tumor suppressor protein binds to .beta.-catenin, a protein recently shown to interact with Tcf/Lef transcription factors. Here, the gene encoding a Tcf family member that is expressed in colonic epithelium (hTcf-4) was cloned and characterized. hTcf-4 transactivates transcription only when associated with .beta.-catenin. Nuclei of APC-/- colon carcinoma cells were found to contain a stable .beta.-catenin-hTCF-4 complex that was constitutively active, as measured by transcription of a Tcf reporter gene. Reintroduction of APC removed .beta.-catenin from hTcf4 and abrogated the transcriptional transactivation. Constitutive transcription of TCF target genes, caused by loss of APC function, may be a crucial event in the early transformation of colonic epithelium. It is also shown here that the products of mutant APC genes found in colorectal tumors are defective in regulating .beta.-catenin/Tcf-4 transcriptional activation. Furthermore, colorectal tumors with intact APC genes were shown to contain subtle activating mutations of .beta.-catenin that altered functionally significant phosphorylation sites. These results indicate that regulation of .beta.-catenin is critical to APC's tumor suppressive effect and that this regulation can be circumvented by mutations in either APC or .beta.-catenin.

Abstract: Absorbent devices, and more particularly absorbent devices that are worn interlabially by female wearers for catamenial purposes, incontinence protection, or both, that have an emollient composition on their body-contacting surface are disclosed. The interlabial device has a body contacting surface that is pre-moistened or pre-heated with an emollient to prevent drying of the wearer's labial tissue and to reduce friction of the structure against the wearer's labial tissue. The absorbent device is preferably capable of maintaining contact with the inside surfaces of the wearer's labial majors when worn. The emollient composition comprises a plastic or fluid emollient such as mineral oil, petrolatum and/or polysiloxane an immobilizing agent such as a fatty alcohol or wax to immobilize the emollient on the body-contacting surface of the device, and optionally a hydrophilic surfactant to improve wettability of the coated surface. Because the emollient is substantially immobilized on the surface of the absorbent device, less emollient is required to impart the desired therapeutic or protective emollient coating benefits.
