Title: Circuit for pulsed operation of a discharge lamp
Inventor: HUBER ANDREAS
IPC: H05B41/288
Filed: 1996-04-19
Abstract: To provide for automatic switch-over between a power phase and a holding phase in operation of a discharge lamp (EL), a choke or ballast coil (L), serially connected to the discharge lamp, is constructed to have, with respect to current flow therethrough, a non-linear reactance value; the choke or ballast coil is wound on a core which, for example, can be a E-core in which the center leg is of reduced cross-section with respect to the outer legs; or, if one is a torroidal coil on a ring core, the ring core is preferably made of two core elements of different magnetic characteristics, connected together, for example by an adhesive, in which one core element is of low permeability material, such as iron powder or permaloy with high saturation magnetization, and a second core is formed of ferrite with low saturation magnetization.  Current flow through the coil and the serially connected lamp is controlled by alternately operating switch elements (S1, S2), typically insulated gate bipolar transistors, to supply power bursts of, for example, between 20 and 30 A during a second operating phase, separated by a first operating phase of between 0.3 A and 0.5 A at a substantially higher frequency than the frequency of the power bursts, and lasting 10 to 30 times as long as the power bursts. An ignition circuit (Z, L-CR) is provided to start or fire the lamp.

Inventor: KONOTOPSKY WILLIAM
IPC: A63F11/00
Filed: 1996-06-28
Abstract: A washer toss game apparatus is disclosed comprising: a planar member having a hole through a central portion thereof; and an upright support member which has three lateral grooves through a central portion thereof, each which closely f its an edge of the planar member.  The planar member accordingly may be positioned at three different levels of inclination. The planar member is additionally provided with a non-slip resilient planar strip on one side thereof, so that when this side is positioned upwardly the washers are more easily tossed and maintained on the planar surface. By increasing the angle of inclination of the planar member and turning the slippery side upwards the difficulty of scoring can be increased. Each player alternatively tosses four washers in a round. All washers of one player which are closer to the hole than any of the washers of the other player score points. Three points are awarded for a washer passing through the hole; one point for other scoring washers.          Additional rounds are played until one side achieves and wins with 21 points.

Patent CA-2193440-A1 (CA)
Inventor: PADGETT ALLAN P
IPC: G06F3/0484
Filed: 1996-12-19
Abstract: An improved technique for highlighting text objects accurately, reliably and quickly is disclosed.  The technique minimizes the number of expensive region operations required to produce the necessary highlighting by combining bounding boxes of adjacent objects (e.g., words) using rectangle operations.  The resulting rectangles are then used to form a region.  The complexity of the regions is limited by limiting the number of rectangles that can be included within a region.  Once a region is formed, the pixels of a display screen that are within the region are inverted to designate the objects within the region.  However, before inverting the pixels, any overlap of the region with a previously highlighted region is eliminated or clipped from the region.  The portion of overlap can be determined by rectangle operations instead of expensive region operations.  As a result, double inverts which have plagued highlighting of having objects that can be placed at any position or rotation are eliminated in an efficient manner.

Title: Multi-cartridge medication injection device
Inventor: SCHOENBERG STEPHEN J
IPC: A61M5/315
Filed: 1996-04-18
Abstract: A multi-cartridge dispenser (40) for delivering two liquid medications through a single needle (41). The dispenser includes independent dual channel metering mechanisms (58), dual channel drive mechanisms (68, 88, 118, 132), and dual channel lock and pullback mechanisms (138, 148). The wing (132) must be in its "up" position for metering to take place. The wing reciprocatingly moves a driver (118) between a pre-injection position and a post-injection position to reciprocatingly advance the leadscrews (118) upon an injection stroke. The dosage indicator (66) automatically rotates to its initial zero position upon the injection stroke. The lock and pullback mechanism automatically prevents rotation of the leadscrew upon metering and injection. It also locks out the cartridge retainers (188) so that the retainers can be removed from the housing (42) only while the wing is in its "down" position. The pullback sleeve (148) unloads a pullback key (138) during a cartridge (184) change in order to enable the leadscrew to be spun freely back to its home position.

Title: Gravity concentrated carbon dioxide eor process
Inventor: WADLEIGH EUGENE E
IPC: E21B43/16
Filed: 1997-09-22
Abstract: This invention relates to the recovery of oil from an oil-bearing formation having a natural fracture network with substantial vertical communication and wherein gravity drainage is the primary means of recovery. A downwardly inflating gas-cap is pressured up with a chase gas having a density less than that of CO2.CO2 is injected and a CO2-rich displacing slug is formed at the gas-liquid hydrocarbon contact. The chase gas is injected to facilitate displacing downwardly the CO2-rich displacing slug to recover hydrocarbon from the reservoir. CO2 is replaced in the displacing slug as the CO2 is solubilized into the oil, including matrix oil, to facilitate recovery thereof. The oil is recovered through production wells in fluid communication with the reservoir, preferably the inlet to the well is below the water-liquid hydrocarbon contact at such a level to prevent free-gas production. The chase gas has a density less than that of the CO2 and is comprised mostly of nitrogen; however, it can contain other gases such as methane, ethane, CO2, and miscellaneous gases. The chase gas is injected at a rate to minimize mixing of the chase gas with the CO2 and to facilitate gravity segregation of the CO2 from the chase gas. The CO2 in the CO2-rich displacing slug can be replenished by incorporating CO2 into the chase gas and permitting the CO2 to gravity segregate downwardly while the less dense gases move upwardly.
