Patent CA-2952819-C (CA)
Title: Synchronic dual packer
Inventor: FLORES JUAN CARLOS
IPC: E21B33/12
Filed: 2015-06-09
Granted: 2022-07-19
Abstract: A downhole tool having a first packing element and a second packing element configured to synchronically set to selectively hydraulically isolate a portion of the wellbore. The movement of a pin along a j-slot track on a second sleeve sets the second packer in compression and the movement of a pin along a j-slot track on a first sleeve the first packer in tension after the second packer has been set. The j-slot track on the first sleeve has six different pin positions and the j-slot track on the second sleeve has four different pin positions. The pin positions and direction of travel of the j-slot tracks are adapted to permit the synchronized setting of the two packing elements to hydraulically isolate a portion of the wellbore. The wellbore may then be treated by flowing fluid out of a ported sub positioned between the packing elements.

Granted: 2022-11-29
Abstract: Disclosed is a flux injector assembly and method for refining a molten material, wherein at least a portion of the material is aluminum, as it flows through a trough. A dispensing rod having a hollow body and a dispensing rim is configured to allow a flux and/or inert gas to travel through the hollow body and be injected into the molten material through the dispensing rim as the molten material flows through the trough. A baffle plate is configured to be positioned within the molten material in the associated trough to allow the molten material to flow passed the baffle plate. The elongated dispensing rod is positioned at a downstream location relative to the baffle plate. The rate of flow of molten material is increased as it passes the dispensing rim of the elongated dispensing rod to inject and mix the flux within the molten aluminum alloy.

Title: System, method, and application for exchanging content in a social network environment
Inventor: SAVENOK ALEXANDER
IPC: H04N21/254
Filed: 2017-05-03
Granted: 2020-04-14
Abstract: Users share live (SHARE LIVE) content in real-time by sharing socially- targeted user-selected/generated content while simultaneously consuming content from any integrated content provider. In the context of an exemplary music-based scenario, the user, while listening to music from any integrated music provider, may initiate a SHARE LIVE session such that concurrent data streams are maintained and media playback information is managed separately from media content playback channels. Information about playback events is continuously transmitted via facilitated sockets. Other users may consume shared content (LISTEN LIVE) by tapping a proprietary resolution method to identify and properly source the media content files the broadcaster is sharing. Independent social broadcast streams may also be overlaid atop the direct playback of media content from a preferred provider as governed by the proprietary resolution method. An event-handling micro-service maintains and combines the broadcaster's content playback actions and social content, which are synchronized on multiple user devices.
