Patent CA-2922688-A1 (CA)
Title: Composites for use in stimulation and sand control operations
Inventor: MONROE TERRY D
IPC: C09K8/80
Filed: 2014-09-19
Abstract: A composite having a solid particulate and a surface modifying treatment agent on the solid particulate wherein the surface modifying treatment agent has a hydrophobic tail and an anchor for adhering the hydrophobic tail onto the solid particulate. The anchor may be metal and the hydrophobic tail may be an organo-silicon material, a fluorinated hydrocarbon or both an organo-silicon material and a fluorinated hydrocarbon. The composite may be used as a proppant in a hydraulic fracturing operation as well as a sand control particulate in a gravel packing operation. The presence of the surface modifying treatment agent on the surface of the solid particulate reduces the generation of fines and dust as well as the migration of sand during a hydraulic fracturing operation or a sand control operation. The presence of the surface modifying treatment agent on the surface of the solid particulate further enhances the crush resistance of the solid particulate.

Title: Methods for post-fabrication functionalization of poly(ester ureas)
Inventor: LIN FEI
IPC: C08G75/02
Filed: 2014-09-30
Abstract: Amino acid-based poly(ester urea)s (PEU) are emerging as a class of polymers that have shown promise in regenerative medicine applications. Embodiments of the invention relate to the synthesis of PEUs carrying pendent "clickable" groups on modified tyrosine amino acids. The pendent species include alkyne, azide, alkene, tyrosine-phenol, and ketone groups. PEUs with Mw exceeding 100k Da were obtained via interfacial polycondensation methods and the concentration of pendent groups was varied by copolymerization. The incorporation of derivatizable functionalities is demonstrated using 1H NMR and UV-Vis spectroscopy methods. Electrospinning was used to fabricate PEU nanofibers with a diameters ranging from 350 nm to 500 nm. The nanofiber matricies possess mechanical strengths suitable for tissue engineering (Young's modulus: 30045 MPa; tensile stress: 8.51.2 MPa). A series of bioactive peptides and fluorescent molecules were conjugated to the surface of the nanofibers following electrospinning using bio-orthogonal reactions in aqueous media.

Patent CA-2956033-A1 (CA)
Inventor: BULMER JAMES H
IPC: H01R13/533
Filed: 2017-01-25
Abstract: An electrical plug and receptacle can be connected and disconnected in the presence of explosive gas without causing a spark and possible explosion. Power is disconnected from the receptacle unless the plug is fully inserted and locked into position in the receptacle. A sensor detects when the plug is fully inserted and locked. The sensor energizes a relay which allows power to flow to the receptacle and the connected plug. The relay is encapsulated in epoxy or isolated in a Restricted Breathing enclosure to keep explosive gas away from the sparking relay contacts. To remove the plug from the receptacle, it must first be unlocked. The sensor detects the motion of unlocking the plug and releases the relay to disconnect power from the plug and receptacle so that no spark is created when the plug is removed from the receptacle. Ordinary NEMA plugs and receptacles can be used in Zone 2 and Class I Division 2 hazardous locations.
