Abstract: A tool carrier, which is also known as a top drive or a power swivel, for a well operation rig includes link arms coupled between the rotating hook assembly and the lower pipe gripping structure, the link arms each secured to the rotating hook assembly by a first rigid connection and secured to the lower pipe gripping structure by a second rigid connection such that the link arms can extend along well center even when operating in slant. Another tool carrier includes a hinge between the mast and the main housing. The hinge permits the tool carrier to be moved into a more central position when folded onto the rig chassis for transport.

Abstract: The invention relates to a shaving razor. The shaving razor includes a handle having an elongated body having a proximal end and an opposing distal end. The proximal end has a cartridge connection mechanism and a razor cartridge connected to the cartridge connection mechanism. The elongated body has a first section nearest the proximal end and a second section nearest the distal end and a movement member connecting the first section to the second section. The movement member includes a unitary member having a central core extending along a longitudinal axis. A plurality of spaced apart projections extend outward from the central core and perpendicular to the longitudinal axis of the central core. Adjacent projections are spaced apart from one another to form open slots between adjacent projections.

Abstract: A collaborative authoring application provides an authoring environment in which two or more users can edit a document concurrently. Each user edits a copy of the document, sends updates to a master copy of the document, and receives updates from the master copy of the document. The authoring environment generally inhibits the users from providing conflicting editing instructions to the master copy of the document. For example, each user can generate a content lock about one or more data units within the document. The authoring environment may synchronize content locks automatically and content only at the request of the user.

Abstract: A novel razor cartridge includes at least one non-cutting element disposed anywhere within a blade array between a guard and a cap and/or in a blade position of a frame providing skin/hair management. This non-cutting element allows the fine-tuning of parameters such as blade-skin contact, hair orientation, blade spans and rinse-through gaps in manners that improve shaving comfort, closeness, efficiency, and/or rinse-ability. The non-cutting element may include projections, fin-like elements, comb-like features having teeth, exfoliation or lubricating capabilities. By having a fixed non-cutting element disposed midway in a blade array, a multi-stage cartridge is provided with a middle control point with potentially different functionality before and after the non-cutting element. The non-cutting element is not attached to another blade in the blade array though it may be manufactured as a modified blade support, attached to a blade support, or as part of the frame or the clips.

Abstract: A radio frequency integrated circuit switch includes a semiconductor die with a transistor having a gate on a first-side (e.g., front-side) of the semiconductor die. The semiconductor die may include a bulk semiconductor substrate or wafer (e.g., silicon substrate or wafer). The semiconductor die may also include a first deep trench isolation (DTI) region that extends from the front-side to a backside opposite the front-side of the semiconductor die. The radio frequency integrated circuit switch further includes a body contact layer on the backside of the semiconductor die. The body contact layer is coupled to a backside of a body of the transistor. The body of the transistor may have a first P-type region (e.g., a P+ region).

Abstract: An unmanned aerial vehicle (“UAV”) is provided for the lifting and carrying payloads of up to 100 kg. The UAV can include a pair of counter-rotating propellers enclosed in a cage with attitude control motors for providing directional thrust mounted on the top of the cage. One or more motors can rotate the propellers via co-axially concentric vertical output shafts. The motor can include an internal combustion motor or an electric motor.

Abstract: A slips positioning apparatus for a wellhead installation is installed in a fixed position relative to the blow out preventer and allows releasable locking of the slips relative to well center and driving movement of the slips relative to well center. The slips positioning apparatus includes a slips-mounting structure for accepting connection of the slips; an installation structure for mounting the apparatus rigidly above the blow out preventer and relative to well center. The installation structure is a plate that defines a first plane. The apparatus further includes a first and a second linear guides configured for movement of the slips-mounting structure relative to the installation structure along respective first and second directions in planes substantially parallel with the first plane; and first and second linear actuators for moving the slips-mounting structure respectively along the first and second linear guides.

Abstract: The concepts relate to data handling, and more specifically to data handling scenarios where data is revised on one computer and stored on another computer. One example can obtain a set of blobs relating to revisions of a file. The example can determine a target size of datastore blobs. In an instance where a total size of the set of blobs is less than the target size, this example can aggregate the set of blobs into an individual datastore blob. Otherwise, the example can identify new or edited individual blobs of the set and aggregate the new or edited individual blobs into first datastore blobs. The example can also aggregate other individual blobs of the set into second datastore blobs.

Abstract: Methods of forming an article from a molten plastic composition comprising a polymer and a blowing agent. The methods include injecting the molten plastic composition into a mould, allowing the plastic composition to form a first solid skin adjacent to an in contact with a first cavity-forming surface of the mould and a second solid skin adjacent to and in contact with a second cavity-forming surface of the mould, and then opening the mould before the molten plastic composition between the first and second solid skins in at least one portion of the circumference of a region of the mould cavity defining an annular cross-section of the cavity has solidified.

Abstract: For wellbore operations, a pipe handler moves pipe up to a rig floor. A pipe loader moves pipe from a presented position into alignment with well center. The pipe handler moves pipe up to a slanted presented position. The slanted presented position can be adjusted by manipulating the drive system.

Abstract: Imaging systems including an objective lens and a line generation module are described herein. The objective lens may focus a first light beam emitted by the line generation module and a second light beam emitted by the line generation module at a focal point external to a sample so as to adjust line width. Line width may be increased to lower overall power density of a light beam on a surface of the sample such that the power density of the light beam on the surface of the sample is below a photosaturation threshold of a dye on the sample.
