A tool for forming a piston having a plurality of circumferential seals for use in a cartridge for dispensing multi-part fluids, the tool comprising a plurality of segments together defining a piston cavity corresponding to an outer periphery of the piston.

Abstract: Various embodiments of the present disclosure provide a cartridge for dispensing two-part fluids. In one embodiment, the cartridge comprises a cartridge body having a dispensing end and defining a first fluid reservoir and a second fluid reservoir. The dispensing end defines at least one aperture fluidly connected to the first fluid reservoir. The dispensing end also defines a dispensing conduit fluidly connected to the second fluid reservoir. The cartridge further comprises a nozzle member engageable with the cartridge body to form an outlet and to fluidly connect the at least one aperture to the outlet.

Abstract: Various embodiments of the present disclosure provide a masonry member comprising an anchor member and a sleeve. The anchor member has a shank with a ridge formed thereon, the ridge extending radially outwardly from and along a surface of the shank generally from a distal end of the anchor member toward a head of the anchor member. The sleeve defines a groove. The sleeve is coaxial with and at least partially surrounds the anchor member such that the ridge of the shank is at least partially received in the groove. A cross-sectional width of at least one of the ridge and the groove reduces in a direction extending toward the head of the anchor member so withdrawal of the anchor member through the sleeve expands at least part of the sleeve radially outwardly.

Abstract: A master processing apparatus is disclosed. The master processing apparatus has first and second pressure applying rollers, and a plurality of gears configured to drive the rollers in response to received input torque. The master processing apparatus further has a pivot plate, connected to the first pressure applying roller and the plurality of gears, allowing a range of movement for the first pressure applying roller, while the plurality of gears may remain intermeshed. The master processing apparatus further has a torsion spring about the pivot plate gear axis, configured to bias the pivot plate and first pressure applying roller towards the second pressure applying roller. Other objects, features, and advantages are also disclosed.

Abstract: An edge protector which can be applied to complex curved edges without on-site adaptation has interconnected elements 2 aligned in a longitudinal direction. Each of the elements has first and second opposing side walls 3 and 4 joined by an end wall 5 and an intermediate wall 6 to form a box section 7, and opposing faces of the side walls 3 and 4 which project beyond the box section are each provided with elastomeric gripping projections 8 and 9. Adjacent pairs of elements are spaced apart to form a gap 11 and interconnected by an integral hinge connection between one of said side and end walls 3, 4 or 5. A single edge protector may include adjacent pairs of elements interconnected by hinge connections between one of their side walls 3, 4 and adjacent pairs of elements interconnected by hinge connections between their end walls 5 allowing the edge protector to be manually manipulated in two mutually perpendicular planes.

Abstract: A pair of opposing side walls (23, 24) are joined by substantially perpendicular bridging walls (31, 32) provided with an outer wall (41, 42) which is spaced from the bridging wall by a longitudinal connecting wall (43) and spaced transverse connecting walls (44). The outer wall (41, 42) is intended to be crushed under the force of a heavy impact. The longitudinal wall (43) is offset from the centre line so that even in the event of a square-on impact the outer wall can still deform inwardly on one side. The inner faces of the bridging walls (31, 32) include a longitudinally-extending support surface bounded by side channels (36, 37) having side faces which are coplanar with the inner faces of the side walls (23, 24). Such an arrangement allows the side walls to flex outwardly within the depth of the channels and provides an improved grip and improved tolerance with respect to the thickness of the protected article.

Abstract: A corner protector, e.g. for a sheet of glass, has a pair of generally triangular side walls connected by a pair of substantially perpendicular bridging walls. The internal faces of the bridging walls are substantially flat and are separated by a recess. Internal channels are provided along the junction between the side walls and the bridging walls. The margins of the side walls which extend between the outer ends of the bridging walls are curved such that they are mutually offset from each other for most of their length. At least one of the side walls contains a through-aperture for receiving an adhesive pad which adheres to the protected article in use to hold the corner protector in place. A finger notch provides access to an edge of the adhesive pad to facilitate peeling in order to remove the corner protector.

Abstract: A corner protector, e.g. for a sheet of glass, has a pair of generally triangular side walls 23, 24 connected by a pair of substantially perpendicular bridging walls 25 and 26. The internal faces of the bridging walls are substantially flat and are separated by a recess. Internal channels are provided along the junction between the side walls and the bridging walls, which reduces stresses at the junction between the side and edge faces of a protected article during impacts with the corner protector. The margins 27 of the side walls which extend between the outer ends of the bridging walls are curved such that they are mutually offset from each other for most of their length. At least one of the side walls 23, 24 contains a through-aperture 40 for receiving an adhesive pad which adheres to the protected article in use to hold the corner protector in place.
