摘要:
A fastener assembly includes an elongate fastener, and a support collar mounted on the elongate fastener. The support collar is shaped such that it has profiles on opposite sides of the elongate fastener that are asymmetric with respect to each other. The asymmetry may be an asymmetry in the number, shape, position, or size of recesses on two opposite sides of the elongate fastener. A plurality of fastener assemblies may be provided as a fastener strip, in which each support collar is joined to one or two adjacent support collars in a strip.

Performance, properties and stability of bifunctional air electrodes may be improved by using modified current collectors, and improving water wettability of air electrode structures. This invention provides information on creating non-corroding, electrically rechargeable, bifunctional air electrodes. In some embodiments, this bifunctional air electrode includes a corrosion-resistant outer layer and an electrically conductive inner layer. In some embodiments, this bifunctional air electrode includes titanium suboxides formed by reducing titanium dioxide. Titanium suboxides may be corrosion-resistant and electrically conductive.
摘要:
A brake system for a motor vehicle having an at least single-circuit brake cylinder with the aid of which a brake force may be applied to at least one wheel of the motor vehicle when actuated. The brake cylinder is mechanically operatively connected to a booster cylinder, which is decoupled from brake setpoint detector and is hydraulically triggerable for actuation of the brake cylinder corresponding to the driver's intent as detected with the aid of the brake setpoint detector. A motor vehicle having a brake system is also described.
摘要:
A brake system for a vehicle having a master brake cylinder, which provides a pressure signal, having a brake-medium reservoir connected to the master brake cylinder, and a first brake circuit, which is coupled by a first input to the master brake cylinder and by a second input to the brake-medium reservoir, and having at least one first wheel brake cylinder, which is mounted at a first wheel, in order to exert a force corresponding to the pressure signal onto the first wheel, and having a separator valve, which is configured between the first input and the first wheel-brake cylinder, to prevent further transmission of the pressure signal upon receipt of a supplied closing signal; and having a control valve, which is configured between the first input and the first wheel-brake cylinder; in order to control an inflow of a brake medium from brake-medium reservoir to the first wheel-brake cylinder. In addition, a method for controlling a corresponding brake system is also described.

A power tool cooling system comprises a cooling fan disposed on a motor in a position between the upper field coil and the lower commutator. A transmission housing encapsulates the transmission mechanism. During operation, the fan is driven by the motor and draws air axially through the motor and expels the air radially outwardly through holes in the outer housing of the motor. This causes air to be drawn in through the air vents formed on the top of a tool housing, in the side of the housing and between the housing and a battery pack. The cool air flows outside of the transmission housing, but inside the tool housing such that air does not pass through the transmission mechanism. A plurality of motor openings are also formed in the outer housing of the motor to enable cool air to pass into the motor to cool the motor.

A fastener driving tool arranged to drive fasteners into a workpiece includes at least one electric motor having a central stator and an external rotor arranged to rotate around the stator. The rotor may be in the form of a flywheel. The tool includes an energy transfer member such as a driver arranged to transfer kinetic energy from the rotor to a fastener held in the tool, thereby to drive the fastener from the tool into a workpiece. The electric motor may be a brushless motor. The tool may include two such motors, arranged such that both of their rotors propel the driver simultaneously.

A fastener supply assembly for a fastener driving tool includes an outlet passage arranged to expel fasteners from the assembly to a workpiece during use, a magazine comprising a plurality of supply channels arranged to hold fasteners and supply them to the outlet passage, and a channel selector. The channel select has an opening and is arranged to selectively connect, via its opening, the outlet passage with each respective supply channel of the magazine, by movement of the channel selector relative to both the magazine and a longitudinal axis of the outlet passage. The movement of the channel selector may comprise rotation about the longitudinal axis of the outlet passage.

A fastener outlet assembly for a fastener driving tool includes: an outlet passage arranged to expel fasteners from the assembly to a workpiece during use, the outlet passage having one or more walls; and a detector arranged to detect whether a fastener is present in the outlet passage. The detector comprises at least part of a cover that provides at least part of a wall of the outlet passage, the cover being movable with respect to the remainder of the outlet passage to open the outlet passage and gain access thereto.
摘要:
A gear wheel is rotatably mounted on a drive shaft. The drive shaft has a plurality of longitudinal splines formed thereon. A drive sleeve surrounds the drive shaft and has a plurality of the inner splines formed on its interior surface. The inner splines slidably intermesh with outer splines of the drive shaft such that the drive sleeve can slide up and down on but cannot rotate relative to the drive shaft. A coil spring biases the drive sleeve downwardly. Drive sleeve teeth are formed around the bottom edge of the drive sleeve. Corresponding gear plate teeth are formed on the upper surface of the gear wheel and are adapted to engage the drive sleeve teeth when the drive sleeve is in its downward most position under the influence of the coil spring. In this position, the gear wheel is operatively coupled to the drive shaft.
