Abstract: A drilling fluid may include a carrier and a lubricant composition. The lubricant composition includes ethylene bottoms heavy pyrolysis oil. For example, the heavy pyrolysis oil may be bottoms of a fractionated fuel oil product separated from ethylene gas produced by a cracking of a hydrocarbon feedstock in a furnace.

Abstract: A water-based drilling mud composition may include an aqueous carrier, an asphalt sulfonate salt, and insoluble latex particles. The insoluble latex particles promote stabilization of an emulsion formed in response to introduction of an oil phase in the composition. The composition may include the emulsion including an oil phase dispersed as droplets in the aqueous carrier. The dispersed insoluble latex particles may be present in an oil-water interface between the oil phase and an aqueous phase of the aqueous carrier.

Abstract: A method, system and non-transitory program storage device for creation of a signature on a client device comprises displaying a preview area comprising a layout being selectable by a user. The layout comprises a plurality of portions being arranged to form a signature. The portions are operable for displaying images, video, text, logos, hyperlinks and Really Simple Syndication (RSS). A displayed a data entry area is operable for accepting user inputs for presentation in the portions. Accepted user inputs are previewed in the preview area while accepting user inputs. The signature comprising portions with user inputs is saved. The saved signature is accessible to the user for attachment to electronic documents.

Abstract: Door control apparatus is provided for a sliding door for use with a boat or a ship. The door control apparatus is unbiased in either direction and will substantially maintain any position in which it is placed, except during extreme rolling or pitching of the boat or ship due to heavy weather conditions. The door control apparatus provides for equal but opposite force to open the door as to close the door. The door control apparatus includes piston and cylinder means with fixed orifices. Other than the piston its associated parts, there are no moving parts to the mechanism.
