A multiple lumen catheter assembly comprising a first catheter having a proximal end and a distal end, a second catheter having a proximal end and a distal end; and a connecting means for selectively joining at least a portion of the distal ends of the first and second catheters.

A retaining ring installation tool for use in installing retaining rings onto shafts and into bores is formed from a single piece of metal to define a cylindrical, elongated body. A hollow cavity is formed in one end of the body and the wall of the body that defines the cavity is slotted to form a plurality of individual, flexible spring contact arms or fingers which extend forwardly from a rear body portion and which collectively define an insertion end of the tool. The ends of the fingers are enlarged to ensure contact occurs between the tool and the retaining ring during the installation of the ring onto a shaft or into a bore. The contact arms are bent either radially inwardly or outwardly so that they will contact the retaining ring at all times during installation of the ring.

A piston for a brake caliper of a disc brake constructed as a pot which is open at one end, having a longitudinal axis, a wall, and a piston head. The piston is supported in a cylinder of the brake caliper such that it can be moved along the longitudinal direction, and it can be placed against a brake pad in the region of the piston head by an axial contact surface. When the piston is subjected to pressure by a hydraulic fluid, the piston moves in the cylinder and presses the brake pad against a brake disc. A projection having a conical surface is provided on an inner surface of the piston head. A recess is provided, which is substantially at the same distance from the longitudinal axis as the projection on the inner surface of the piston head, on an outer surface of the piston head.

A slide fastener (1) comprising a pair of tapes (2), carrying respective teeth (3), a top stop (4) and a die-cast or injection-molded slider (5), said slider (5) having a structure with an upper blade (8), a lower blade (9), lateral flanges (10, 11) and a diamond (20) connecting the upper and lower blades, wherein a cavity (21) is formed in said diamond (20).

A bicycle fork includes a fork shaft configured to be rotatably borne by headset bearings in a head tube of a bicycle frame so as to rotate about a steering axis. The fork shaft includes a cylindrical fork shaft segment that is disposed eccentrically with respect to the steering axis. The cylindrical fork shaft segment is a right circular cylinder having a hollow interior, a cylindrical inner surface and a central longitudinal axis that lies within a symmetry plane of the bicycle frame and extends parallel to the steering axis. The central longitudinal axis of the cylindrical fork shaft segment is spaced apart from the steering axis in a direction of eccentricity that points in an opposite direction with respect to a forward direction of travel of the bicycle.

The invention relates to an axle body, particularly for a commercial vehicle, wherein the body is configured substantially as an axle pipe, which comprises a center section and at least one receiving section connected thereto for receiving an axle guide, wherein the axle body in the center section has a substantially constant wall thickness, and wherein the axle body in the receiving section, at least in some regions, has a wall thickness that is greater than the wall thickness of the center section.

A crack-propagation line is separate from a seal joining two shells of a confectionery packaging. The confectionery packaging is opened by separating the packaging along the crack-propagation line such that a portion of at least one of the parts of the confectionery packaging is broken to form an opening through which the packaged confectionery can be removed. Consequently, there is provided a method of forming a confectionery packaging and a method of packaging a confectionery product wherein two shells of a confectionery packaging are sealed together and a crack-propagation line is formed in a portion of at least one of the parts of the confectionery packaging. Suitably, the crack-propagation line extends away from the seal joining the two parts. The confectionery packaging is opened by separating at least one of the parts of the confectionery packaging, leaving the seal substantially unaffected. The additional step of forming a separate crack-propagation line rather than intending the confectionery packaging to be opened by separating the two parts through the seal provides improved opening characteristics.

A method of fabricating a circular-shaped metal structure includes the steps of (a) rotating a pipe around an axis thereof, the pipe being composed of a plastic-workable metal, (b) moving a jig towards the pipe in a direction perpendicular to the axis until the jig makes contact with an outer surface of the pipe, and compressing the jig onto the pipe, (c) moving the jig in a direction in parallel with the axis with the jig being compressed onto the pipe while the pipe is kept rotated, (d) measuring a thickness of a wall of the pipe during the step (c), and (e) adjusting a pressure with which the jig is compressed onto the pipe, in accordance with the thickness measured in the step (d).

The invention relates to an implant system comprising a dental implant (10) made of ceramic material and a structural part (12), wherein the structural part (12) comprises a first anti-rotation element with a plurality of grooves and the dental implant (10) Comprising a second anti-rotation element with ribs complementary to the first anti-rotation element, wherein the groove is open towards the proximal end (28) of the structural part (12).

The burner, particularly a gas turbine burner, comprises a central fuel supply arrangement (27) and an annular air-duct (17) for supplying combustion air and twisting the blades (19) that are arranged in the annular air-duct. The gas nozzles (21) are provided in the fuel supply arrangement by a gas distributor channel (29). Other gas nozzles (23) are provided in the fuel supply arrangement by another gas distributor channel (31). A gas supply pipe (41) has a gas supply channel (35).
