摘要:
A method for preventing combustion chamber deposits from causing start-failures in an internal combustion engine comprises operating the engine with a fuel composition that contains a normally liquid fuel and a nitrogen-containing detergent that includes a polyetheramine; a Mannich reaction product of a hydrocarbyl-substituted phenol, an aldehyde and an amine; or a mixture there. The method is effective in preventing start-failures in multi-valve, low friction, spark-ignited engines.

An apparatus for transmission of rotation between a first rotational member and a second rotational member comprises a first gear member mounted for rotation about an axis and coupled for rotation to the first rotational member. An eccentric gear arrangement is mounted eccentrically with respect to the axis and has a first eccentric gear portion for engagement with the first gear member and a second eccentric gear portion for engagement with a second gear member. Crank means couple the eccentrically mounted gear arrangement to the second rotational member, whereby orbital motion of the eccentric gear arrangement about the axis is transmitted to the second rotational member. The first and second eccentric gear portions are coupled for rotation with each other, and the first and second gear members are rotationally independent of each other.

Compositions for caring for contact lenses and eyes include a liquid aqueous medium and a vitamin derivative component present in an amount effective as a surfactant in the composition. The compositions can be used to clean, soak, re-wet and, with the inclusion of a disinfectant, disinfect contact lenses. In addition, the compositions are effective as artificial tears and eye wash solutions. Methods for contact lens care and eye care are also disclosed.

An improved adjustable bridge is described for a stringed musical instrument. The adjustable bridge has a pair of feet attached to the bridge body. A pair of legs is attached for the bridge body using adjustable rod pegs. These rod pegs are adjustable so that the bridge may be moved upwards and downwards to achieve the desired bridge height.

A surge suppression unit comprises connection circuitry for coupling the surge suppression unit in a communication cable. Surge suppression circuitry uses Silicon Avalanche Diodes (SADs) that couple power surges on the communication cable to ground. In one embodiment, the surge suppression unit includes multiple surge suppression modules configured for inserting into different slots in a same enclosure. The surge suppression modules can be quickly and easily inserted and then removed for connection with different communication cables
