Abstract: A carburetor fuel adjustment assembly includes a low speed needle valve and preferably a high speed needle valve threaded into respective receptacles of a carburetor body. Each receptacle defines an elongated cavity which intersects a fuel passage and has a valve orifice or seat. Each needle valve has a shank which threadably engages the respective receptacles and a tip that extends into the axially-aligned orifice or seat. The tip is axially movable relative to the orifice by rotation of the needle valve to control the size of the opening between the valve and orifice for fuel flow. A resilient body cooperates with the valve shank in laterally biasing the tip into a steadfast position relative to the orifice or seat. The lateral bias assures constant area for fuel flow through the orifice by resisting needle movement until a sufficient torque is intentionally applied to the needle valve.

Abstract: A band clamp having a band and a nut and bolt fastener. The band includes radially-extending opposed flanges each having an aperture for receiving the bolt. The bolt has a shank that includes a neck, a threaded body for receiving the nut, and a tapered transition from the neck to the threaded body. In one embodiment, the tapered transition extends only partially around the shank such that a portion of the neck has a common surface with the body. During tightening, the radially inward facing surface of the aperture in the flange can engage the threaded body and slide along the threaded body across the common surface and onto the neck without having to traverse and ride up over the tapered transition. In another embodiment, the nut has an angled shoulder that engages the tapered transition when the nut is tightened to the desired axial position on the bolt.

Abstract: A method, fuel system, and components for facilitating the delivery of liquid fuel from a fuel tank in fluid communication with a float bowl carburetor of an internal combustion engine, wherein evaporative emissions of the fuel from the fuel tank and float bowl carburetor are mitigated. During operation of the engine, fluid communication is permitted between the fuel tank and the carburetor, and fuel vapors at a predetermined threshold superatmospheric pressure are permitted to vent outwardly from the fuel tank. During inoperation of the engine, fluid communication is prevented between the fuel tank and the carburetor, and fuel vapors at a predetermined threshold superatmospheric pressure are permitted to vent outwardly from the fuel tank.

Abstract: A hydraulic cylinder (10) is disclosed comprising a cylinder housing (12) with a housing bore (14), a piston (16) held longitudinally displaceably in the housing bore, a piston rod (18) allocated to the piston and a fixing element (20) which before a first cylinder operation is detachably connected with the piston rod and fixes this in a predetermined stroke position in relation to the cylinder housing and is designed to release the piston rod in relation to the cylinder housing on the first cylinder operation. According to the invention, before the first cylinder operation the fixing element in a first position is detachably connected with a center area (22) of the piston rod and on cylinder first operation can be moved from the first position to a second position area (24), in particular stationary in relation to the piston rod, in which it can be fixed for further cylinder operations.

Abstract: In the method, a tool is tested for an aligning fit or an imbalance in a tool spindle. The tool spindle is set into rotation. A light beam is used to check whether the tool wobbles. The tool spindle and the light beam are moved relative to one another until the light beam impinges on the area covered by the wobbling movement and a received signal generated from the light beam has an intermittent signal path for the first time. The then prevailing relative position between the tool spindle and the light beam is evaluated in respect of a non-aligning fit of the tool or in respect of a tool imbalance.

Abstract: A carburetor throttle valve actuation assembly for a combustion engine is readily adapted for use as a remote control actuator, a local control throttle actuator, or both together providing an optional choice for the end user. The carburetor has a throttle valve having a shaft journaled to a body for movement about a rotation axis. A slave lever connects rigidly to a distal end of the shaft projecting outward from the body. A connection spaced radially outward from the axis engages the slave lever to a radially projecting swivel member of a local, manually operated, throttle valve actuation assembly. The swivel member rotates in unison with the slave lever about the axis, is spaced axially outward from the shaft and is journaled to a bracket engaged rigidly to the body. Preferably, the connection has a hole in the slave lever. If the remote throttle control actuator is used, a Bowden wire engages to a pin projecting axially outward from the slave lever at the hole.
