Abstract: A surgical stapling instrument includes an anvil defining a plurality of staple forming pockets and a stapling head assembly configured to drive a plurality of staples against the staple forming pockets of the anvil. The stapling head assembly comprises a coupling member configured to actuate the anvil relative to the stapling head assembly, a firing assembly configured to drive the plurality of staples against the staple forming pockets of the anvil, and a deck member. The deck member includes a deck surface extending radially between an inner circular edge and an outer circular edge, and a plurality of staple openings extending through the deck surface. The plurality of staple openings define at least one cross shape.

Abstract: An electrically isolated adapter may include a drive body made of first metallic material extending along a common axis, a driven body made of a second metallic material extending along the common axis, and an isolation assembly formed of insulating material disposed between the drive body and the driven body. The drive body may include a drive head configured to interface with a socket or fastener. The insulating material has a resistance to electrical current that is higher than the resistance to electrical current of at least one of the first metallic material and the second metallic material. The driven body may include a drive receiver configured to interface with a protrusion of a driving tool. A portion of one of the drive body or the driven body is received inside a portion of the other of the drive body or the driven body such that the drive body and driven body overlap each other along the common axis.

Abstract: Pitch granules including a core made up of a first composition including at least one pitch, the composition having a penetrability at 25° C. of 0 to 45 1/10 mm, a ring-and-ball softening temperature (TBA) of 55° C. to 175° C., understanding the penetrability as measured according to standard EN 1426 and the TBA as measured according to standard EN 1427, and a layer encapsulating at least one portion of the surface of the core, the layer being made up of a coating composition including at least one anti-caking agent.

Abstract: A bituminous composition is used as an adhesive binder. The bituminous composition has at least one acidic additive of general formula (I): R—(COOH)z in which R is a linear or branched, saturated or unsaturated hydrocarbon-based chain having from 4 to 68 carbon atoms, preferably from 4 to 54 carbon atoms, more preferentially from 4 to 36 carbon atoms and z is an integer ranging from 1 to 4, preferably from 2 to 4.

Abstract: A rotary drill stem for a well including a central tubular element, and first and second connectors each including a threaded portion that can connect the element to another element. At least one of the connectors includes a chamber in communication with a pressure outside the chamber. The connector includes an annular signal transmission coupler. The annular coupler includes a ring having an annular coupling surface. The coupler includes an insulating support that leaves the annular coupling surface free. The coupler includes a piston surface axially opposite to the annular coupling surface. The annular coupler forms a piston.

Abstract: The disclosure relates to a method for preparing crosslinked bitumen/polymer compositions without using any crosslinking agent, wherein at least one bitumen and at least one polymeric composition including at least 80% by mass with respect to the mass of the polymeric composition, of a diblock copolymer of a monovinylaromatic hydrocarbon block and of a conjugate diene block having a molecular mass greater than or equal to 80,000 g mol?1 a content of 1-2 double bond units coming from the conjugate diene greater than or equal to 15% by mass with respect to the total mass of the conjugate diene units, are brought into contact, optionally with stirring, at a temperature between 180° C. and 220° C. for a period of 4 hours to 48 hours.
