Inventor: LEMPERIERE FRANCOIS
IPC: E02B7/06
Filed: 1996-04-16
Abstract: The invention concerns a device for triggering the destruction of a selected part (1, 11) of a hydraulic structure, such as a levee, dike or backfilled dam, the selected part comprising erodable materials such that it can be destroyed by hydraulic erosion. The device comprises at least one solid section (5) which is disposed at the top of the selected part (1, 11) of the structure and is held there by gravity. The size and weight of the solid section (5) are such that it can be expelled by water when the water reaches a predetermined level (N). The vertical dimension of the solid section measured below this predetermined level (N) is such that the outflow released when the solid component has been expelled is of a depth (z) which ensures that the selected part (1, 11) of the hydraulic structure is destroyed reliably and rapidly.

Title: Apparatus and method for filling various containers with liquid or viscous materials
Inventor: SIROIS GABY
IPC: B65B3/28
Filed: 1998-02-27
Abstract: The containers are filled with product whose flow rate, pressure, and density vary; products can range from liquid to paste, with or without chunks.      Product is channeled partly toward the control valve and partly into monitored pressure anal compression chambers.      The first stage in filling the container is accomplished at a faster flow rate (which depends on tie consistency of the substance), while the last stage is slower for the sake of precision in attaining the target weight.      An expert system subjects all process and product variables to servo control in order to provide the efficiency and the yields expected of a packaging process.

Inventor: LATHROP PETER H
IPC: A61N1/04
Filed: 1996-10-17
Abstract: This invention is an electrical stimulation apparatus (10) and method for applying an electrical stimulation to a lesion.   The apparatus includes a housing (12) having a battery and an electrical circuit mounted inside the housing (12). A pair of electrodes (16, 17) are removably mounted to the housing (12) and extend therefrom so as to accommodate being touched to the skin on opposite sides of the lesion. A switch (20) on the housing allows the user to selectively supply electrical energy to the electrodes (16, 17). A first light (40) on the housing is illuminated when the switch (20) is depressed thereby providing a visual indication that electrical energy is being supplied to the electrodes. A second light (41) on the housing provides a visual indication of a low battery condition. A closure (14) is mountable to the housing and encloses the electrodes, switch, and light within the closure. The size and shape of the apparatus are designed for portability.
Patent CA-2238116-A1 (CA)
Title: Pull tab opening system for beverage container
Inventor: KAUFMAN RICHARD HARRY
IPC: B65D75/58
Filed: 1998-05-14
Abstract: An easy-open beverage container and opening system therefor includes an opening provided in a barrier wall.      Covering the opening is a tamper-evident pull tab having a holding portion and a topmost free end portion. An adhesive adheres the holding portion to an outside surface of the barrier wall so that the hole is sealed.      A pair of slits is provided in the holding portion at opposite lateral edges of the holding portion adjacent the free end portion and the respective slits extend inwardly and downwardly away therefrom. The consumer grasps and pulls the non-adhered free end portion downwardly toward an opposite end of the holding portion to expose the opening. This causes a peeled part of the holding portion initially to be pulled from the barrier wall until the slits are reached; at which time the peeled part laterally separates from a remainder of the holding portion initially along the slits and then further along tear lines beginning at the lowermost ends of the slits to expose the opening. Preferably, the adhesive includes a first-strength adhesive and a second-strength adhesive having a strength greater than the first-strength adhesive so that when the peeled part tears downwardly along the tear lines, the tearing force required increases when the peeled part reaches the second-strength adhesive and the consumer can stop peeling at that point so that the peeled part remains attached to the remainder of the holding portion.

Patent CA-2240338-A1 (CA)
Inventor: SWEENEY NIALL
IPC: A61M5/32
Filed: 1998-06-11
Abstract: A shielded needle assembly has an elongate needle that defines an axis having a pointed distal end, a proximal end and a passageway therethrough. The assembly also has a hub that is mountable on a fluid handling device with an axial opening therethrough to receive the needle with the distal end projecting outwardly therefrom so that the fluid handing device is in fluid communication with the passageway. The hub has an annular weakened area therein that defines a needle portion and a fluid handling device attachment portion. The assembly further includes an elongate shield with a proximal end, a distal end and a sidewall that defines a cavity. The shield has a slot extending from the proximal end to the distal end. The shield is attached to the needle attachment portion of the hub with a hinge that provides for pivotal movement of the shield between an open position where the pointed distal end of the needle is exposed for use and a closed position where at least the pointed distal end of the needle is disposed within the cavity through the slot and is substantially protected from inadvertent exposure. In the assembly of the invention, the needle portion and the fluid handling device attachment portion of the hub are frangibly detachable from each other at the annular weakened area by a force applied to the assembly transverse to the axis and distal to the annular weakened area.

Title: A long qt syndrome gene which encodes kvlqt1 and its association with mink
Inventor: CONNORS TIMOTHY D
IPC: C12N15/12
Filed: 1996-12-20
Abstract: One aspect of the invention relates to the identification of the molecular basis of long QT syndrome. More specifically, the invention has identified that mutated KVLQT1 causes long QT syndrome. The analysis of this gene will provide an early diagnosis of subjects with long QT syndrome. The diagnostic methods comprise analyzing the nucleic acid sequence of the KVLQT1 gene of an individual to be tested and comparing them with the nucleic acid sequence of the native, non-variant gene. Alternatively, the amino acid sequence of KVLQT1 may be analyzed for mutations which cause long QT syndrome. Presymptomatic diagnosis of long QT syndrome will enable practitioners to treat this disorder using existing medical therapy. A second aspect of the invention relates to the realization that KVLQT1 coassembles with minK to form a cardiac potassium channel. This allows one to assay for drugs which interact with this channel to identify new drugs which are useful for treating or preventing long QT.
