A method of hanging an object on a wall with a marking device having a threaded shaft, an enlarged diameter head fixed at one end of the shaft, a pointed marking end fixed at an opposite end of the shaft, and a threaded nut mounted on the shaft for axial movement. The shaft of the marking device is positionable into the slot of the item to be hung, and is fixed therein by the nut. Upon positioning of the object and the marking device fixed thereto into desired mounted position on the wall, application of an axial force to the shaft of the marking device will cause a pointed end thereof to create a mark for insulation of a nail or other fastener in the wall at the point of the mark.

Axial flux alternator for a wind turbine arrangement includes at least one magnetic disk including magnets and at least one coil disk including electromagnetic assemblies. One or both disks are mounted to wind turbines such that adjacent disks rotate in opposite directions, or such that the magnets of a magnetic disk move relative to the electromagnetic assemblies of an adjacent coil disk which may move or be stationary, or vice versa. Between adjacent disks, rolling elements on one disk roll, slide or move on or against the surface of the opposite disk in order to fix and maintain air gaps between the magnets on a magnetic disk and magnetic cores of the electromagnetic assemblies on the coil disk, and thus enable continued motion and use of the alternator.

A single-piece slider member (200) is provided for use with a closure device having interlocking fastening strips (108) disposed along opposing side walls (52, 53) of a storage container, such as a conventional plastic bag. The slider member (200) comprises a main body portion (210) which is adapted to be installed upon the interlocking fastening strips (108) and a door portion (240) which is hingedly attached to the main body portion (210) along a hinge portion (241) for movement between open and closed positions. When the main body portion (210) is installed upon the fastening strips (108), the hinge portion (241) is substantially perpendicular to the main body portion (210). The slider member (200) is also provided with a latching mechanism (280) which retains the door portion (240) in the closed position. During assembly, the main body portion (210) of the slider member (200) is installed upon the interlocking fastening strips (108) and then the door portion (240) is moved into the closed position to slidably attach the slider member (200) onto the interlocking fastening strips (108).

A fuel cell vehicle is provided with a fuel cell stack and a vehicle body frame for mounting the fuel cell stack in a front box. The fuel cell stack and a frame member have portions overlapping with each other in a vehicle width direction in a plan view of the vehicle. A vehicle-forward end portion of the fuel cell stack is positioned closer to the rear of the vehicle than a vehicle-forward end portion of the frame member. A vehicle-rearward end portion of the fuel cell stack is positioned closer to the front of the vehicle than a vehicle-rearward end portion of the frame member.

A device for squeezing various household collapsible tubes comprises two lever handles, two pintles, two torsional springs, a primary roller, and a secondary roller. The lever handles are held together by and are free to rotate about the two pintles, forming a double non-crossing class 1 lever arrangement. The rollers, held in gudgeons by snap fit, are also free to rotate. The primary roller is distinguished from the secondary roller by having a crank at one end. The torsional springs, anchored by the pintles, provide a torque which causes the two rollers to clamp together. Operation of the tube squeezing device proceeds by inserting the crimped end of a collapsible tube between the rollers and turning the crank, thereby turning the rollers so as to squeeze the tube flat and to push its contents toward the nozzle end. Insertion and extraction of the tube is effected most readily by applying a compressive force to the two lever handles, creating a gap between the rollers for the tube to easily pass through.

A rechargeable battery pack for a handheld power tool, encompasses a housing and at least one interface unit for establishing a mechanical and electrical connection between the rechargeable battery pack and the handheld power tool and/or a charging device. The interface unit has at least one locking element for locking the rechargeable battery pack onto the handheld power tool, and an actuation element for actuating the locking element. The actuation element encompasses at least one light-emitting element for outputting an optical signal and/or for illumination.

A fuel cell stack includes side plates of a casing. Flanges are provided on the side plates on the short sides for coupling the side plates on the short sides to the other side plates on the long sides.

The assembly comprises a mounting bolt, a base element, and an adjustment sleeve. The adjustment sleeve has a drive portion adapted to be engaged with the nut by frictional drag and rotatable relative to said mounting bolt when said frictional drag has been overcome. The drive portion comprises an internal annular plastic portion which projects from the wall of the adjustment sleeve radially outwards sufficiently so as to frictionally engage the threads of the mounting bolt to provide for said frictional drag.

An apparatus for straightening fluid flow in a conduit or pipeline, such as an irrigation pipeline, resides in an integral assembly of a conical fluid flow displacement member effective to substantially lineralize the velocity profile of fluid flowing through the pipeline and a plurality of circumferentially spaced vanes extending longitudinally and radially of the conical member and effective to mitigate swirl and eccentric velocity profiles in the flowing fluid. The conical member consists simply of a single cone that is centered in the pipeline by the vanes. A bolt extending through the wall of the pipe and threaded into a nut on a vane secures the straightener in the line.
