Title: Gas lighter with dual safety mechanism
Inventor: HSU HUANG-HSI
IPC: F23Q2/28
Filed: 1999-08-12
Abstract: A gas lighter with dual safety mechanism comprises an actuator mechanism provided between an ignition button and a gas fuel reservoir having a push means protruded from a surface of gas lighter, a first elastic member urged against actuator mechanism, a slidably mounted connecting rod on actuator mechanism, and a second elastic member put on a side of connecting rod. In operation, continuously press push means until connecting rod is aligned with ignition button and gas fuel reservoir. Then press ignition button to urge against connecting rod for pivotably rotating a pivotal member to activate a piston of gas fuel reservoir to open an outlet to discharge gas fuel which in turn flows to a tube member for igniting the gas lighter. An ignition is only made possible through activation of actuator mechanism and ignition button and thus, a mechanism for preventing inadvertent ignition of the gas lighter is obtained.

Title: F5-to-f4 oam alarm notification and cell generation in multiple connection atm switches
Inventor: FAHMI MAHER NIHAD
IPC: H04L12/701
Filed: 1999-12-17
Abstract: A method of identifying a segment and end-to-end OAM flow VPC context table for any one of a plurality of VCCs correspon-ding to the VPC. A context table is provided for each VCC. A pointer is provided in each VCC context table. The pointer contains the address of the context table for the segment and end-to-end OAM flow VPC. Once every 500 msec, all provisioned connections sup-ported by the ATM switching system are scanned. In the case of a VCC having an active F4-to-F5 OAM process, the aforementioned pointer is extracted from that VCC's context table, thereby identifying the context table of the corresponding segment and end-to-end OAM flow VPC. If the VPC is in the VP-AIS alarm state, then the current VCC is caused to output a VCC-AIS cell. A continuity check is performed once every 1,000 msec by updating the "CCcount" field in the appropriate F4 OAM connection context table whenever a VCC cell is received on a corresponding F5 connection, preventing the F4 connection from raising a continuity check alarm ("CCalarm"). A similar check is performed if a plurality of F5 connections are aggre-gated into an F4 connection. Whenever a VCC cell is transmitted, the CCcount field in the F4 OAM connection context table is updated, preventing the VPC from entering a CCalarm condition, as aforesaid.      If no VCC cells are transmitted on any of the VPC's VCCs, then the VPC is declared to be in CCalarm condition within 3.5 ~0.5 seconds.

Title: Method and apparatus for percutaneously accessing an implanted port
Inventor: BRUGGER JAMES M
IPC: A61M5/158
Filed: 1998-07-17
Abstract: Methods and apparatus for percutaneously accessing an implanted port uses an access cannula which is periodically introduced to an aperture on the implanted port so that the cannula passes through the same tissue tract. It has been found that repeated passage of the cannula through the same tissue tract creates an artificial passage lined with scar tissue that permits subsequent non-surgical access, reduces patient trauma, minimizes bleeding, and reduces sensitivity. The tract may be initially formed by percutaneously placing a penetrating element through intact skin to the port and leaving the element in place for a time sufficient to create the tract.

Title: Anti-rollover device
Inventor: BARDHAN BIBHUTI BHUSAN
IPC: B60G17/016
Filed: 2000-04-11
Abstract: This is a device or a set of mechanisms that prevents or minimizes the possibility of rollover of a vehicle turning more sharply than is safe. This is achieved by means of a computer continuously calculating the safe limit of sharpness (that is, acuteness or abruptness) of turning of the wheels (and, therefore, of the steering wheel) at any given speed, with any given load in the vehicle, with prevailing road condition, state of tires, etc., etc., and not allowing the wheels (and, ultimately, the steering wheel) to turn, or letting it pass through increasing amount of difficulty as it tends to turn, beyond that said safe limit of sharpness of turning, or, alternatively, automatically reducing the speed of the vehicle to a level safe enough for the approaching and intended sharpness of the turning at the time; this may be accompanied by some warning signals. This invention, called Anti-Rollover Device (or ARO Device or AR Device or AROD or ARD, in short), includes an override or temporarily disabling mechanism to be used as desired.

Title: A pin structure for plug
Inventor: HUANG DONG-YI
IPC: H01R13/04
Filed: 2000-07-31
Abstract: The present invention relates to a pin structure for plug. The pin structure comprises: a first portion and a second portion. The first portion is made of a metal material for electrical connection. The second portion has a circumference, and two opposed sides. The circumference of the second portion is smaller than the first portion. The circumference of the second portion is covered with an isolation layer made of a plastic material for providing a safe and isolation surface. An aperture is formed through two opposed sides. The plastic material of the isolation layer can flow into the aperture to form the isolation layer so as to raise a fixed strength between the isolation layer and the second portion. Besides, the plastic material of the isolation layer can form on the two opposed sides simultaneously so as to shorten a forming time and to reduce the hesitation effect and weld line.
Patent CA-2318157-A1 (CA)
Title: Inflatable packer
Inventor: GILLIES IAN
IPC: E21B33/127
Filed: 1999-01-20
Abstract: This invention relates to hydraulic anchor packers for use in well bores and, more particularly, to inflatable anchor packers. A hydraulic anchor packer (90) is provided having an inflatable packer element (36) incorporating a cylinder (38) and an elastomer sleeve (44) provided on the exterior surface thereof. The elastomer sleeve (44) is retained by retaining means adjacent the cylinder (38) at the end portions of the sleeve (44) but free of the cylinder (38) intermediate the end portions. Means are provided for causing fluid from within the cylinder (38) to flow through an aperture (48) and between the elastomer sleeve (44) and the exterior surface of the cylinder so as to radially expand the sleeve (44). Means are also provided for trapping fluid so as to prevent relaxation of the sleeve (44). Pressure relief means (92, 94,98) permits fluid located exteriorly of the packer (90) to move past the sleeve (44) as the sleeve (44) expands whilst in engagement with a well bore wall during use. Thus, the downhole half of the sleeve (44) may freely expand and displace fluid located below the packer (90).

The valve system comprises a base member which is secured to the collection bag and a movable member which is sealingly fined to the base member; the base member has an open conduct leading into the cavity of the collection bag and conducting liquid to the movable member. The movable member has a discharge tube which is rotatably displaceable with respect to the base member and which is rotated out of the plane defined by the outer surface of the collection bag. The movable member has at least one open position and at least one secured closed position where the discharge tube is pointing upwards. In the open position is the discharge tube rotated to a position situated between more than 90° and less than 180° from upright vertical and here the discharge tube is secured.
