Title: Tamper-evident reclosable plastic bag with breakaway slider
Inventor: ST PHILLIPS ERIC A
IPC: B65D33/34
Filed: 1997-10-14
Abstract: A tamper-evident reclosable plastic bag comprises first and second opposing panels (12, 14), a zipper (22), a slider (32), and an end termination. The first and second oppsosing panels (12, 14) are fixedly connected to each other along a pair of sides and a bottom bridging the pair of sides. The zipper (22) extends along a mouth formed opposite the bottom. The zipper (22) includes a first track with a first profile (24) and a second track with a second profile (28). The first and second profiles (24, 28) are releasably engageable to each other. The slider (32) is slidably mounted to the zipper (22) for movement between a closed position and an open position. The first and second profiles (24, 28) are engaged to each other while the slider (32) is in the closed position. The first and the second profiles (24, 28) are disengaged from each other in response to movement of the slider (32) from the closed position to the open position. The end termination is near one end of the zipper adjacent to one of the pair of sides. To minimize tampering with the plastic bag, a onetime breakable element (36) initially connects the slider to the end termination. The breakable element (36) is intact while the slider is initially in the closed position, and the element is broken in response to movement of the slider from the closed position to the open position.

Patent CA-2290018-A1 (CA)
Inventor: SHAIN ERIC B
IPC: G01N33/543
Filed: 1998-05-15
Abstract: Cette invention se rapporte à des méthodes d'analyse fondées sur la réaction d'un réactif à réponse magnétique soumis à l'influence d'un champ magnétique, qui permettent de mesurer qualitativement ou quantitativement la liaison entre des éléments de paires de liaison spécifiques. Conformément à cette invention, la présence d'un analyte est à l'origine de la liaison ou de la non liaison du réactif à réponse magnétique à un réactif en phase solide, mobile. Le degré de liaison module la réponse du réactif à réponse magnétique ou celle du réactif en phase solide, mobile, ou des deux, à l'influence d'un champ magnétique. De ce fait, la mesure de la réponse au champ magnétique du réactif à réponse magnétique, ou celle du réactif en phase solide, mobile, permet de déterminer avec précision la présence ou la quantité de l'analyte contenu dans un échantillon d'essai. Cette invention fait appel à divers dispositifs pour mettre en oeuvre les méthodes d'analyse décrites ci-dessus.

IPC: F16D65/28
Filed: 1999-11-19
Abstract: An air bag actuated brake cylinder assembly for a railway vehicle braking system is provided which comprises a cylindrical casing engaged with the railway vehicle braking system including a hollow piston assembly having a piston rod assembly attached thereto and mounted for longitudinal movement within the cylindrical casing. An air bag actuator is engageable with the hollow piston assembly and an inner surface of the cylindrical casing for moving the piston and piston rod in an outward direction upon actuation thereof to initiate a braking sequence of the railway vehicle braking system. The air bag actuated brake cylinder assembly of the present invention allows for improved control of the movement of the brake cylinder piston and consequently improved control of the brake shoe forces which is especially desirable during light load conditions. Also, the air bag actuated brake cylinder of the invention is capable of accommodating piston bail and/or misalignment without leaking air. Additionally the air bag actuated brake cylinder assembly of the invention requires less maintenance to maintain the air tightness of the system and allows for the simple replacement of an inflatable bag into the cylinder should an air leak in the actuator occur. Currently used brake cylinder assemblies may be retrofitted with the air bag actuator of the invention.

Title: Fluid-activatable shut-off device
Inventor: EIELSEN JAN INGE
IPC: F16K17/34
Filed: 1998-05-19
Abstract: Fluid-activatable shut-off device in an embodiment as a shut-off valve comprises a valve housing (1) formed with a flow passage (2) threrethrough and a movably supported valve body (3) which is movable between an open valve position, in which the valve body (3) is mainly withdrawn from the flow passage (2), which is thereby essentially cleared, and a closed valve position, in which the valve body blocks the flow passage (2). The valve body (3) is arranged to close the valve by abnormal flow conditions by a portion (7) being formed so that the flowing fluid provides a lifting force which affects the valve body (3) and seeks to move it towards the closed position. The valve body (3) may thereby close by an abnormal increase in the fluid flow rate, density or viscosity. The portion (7) may also be supported by an expansion pad arranged to push the lifting surface further into the flow passage as a consequence of changes in the fluid pressure and/or temperature, thereby providing increased lift so that the valve body (3) closes. The valve portion is equipped with plugs (11) for sequentially shutting off the choke channels to the flow of hydraulic/pneumatic fluid between the chambers 4-6 to thereby control the closing speed of the valve body (3), so that surges is avoided in the pipe system in which the valve is installed.

Patent CA-2308422-A1 (CA)
Title: Quartz substrate heater
Inventor: LAKE ROBIN H
IPC: H05B3/28
Filed: 1998-11-06
Abstract: An electric, resistance element heater utilizes quartz as a sheath material and has a resistance (heating) element that is in intimate, substantially continuous contact with a surface of the quartz. This allows the heater to operate in any one or all of the three modes of heat transfer, namely, radiation, conduction and convection. Such intimate, substantially continuous contact of the resistance element is achieved by applying the element in direct contact with the quartz surface. This is accomplished by applying a heating circuit directly to the quartz surface, which heating element can be a foil element, or a thick or a thin film deposition element. The overall heater is formed by covering the heater element by a quartz sheath and attaching leads formed on the ends of the heater element to a source of electric energy.  Sensors such as thermocouples, RTD's and the like can also be incorporated directly into the heater structure. Also, the heater can be fashioned into a variety of shapes.
