Abstract: Towelette dispenser and vapor impervious pouch containing a roll or web of absorbent material, such as nonwoven fibrous towelettes pre-moistened with a chemical-containing aqueous or other fluid solution. The pouch is sealed before use to prevent the loss of moisture from the pre-moistened towelette roll and is opened at the point of, and at the time of, first use. A double lid is adapted to provide moisture seal between usages of the pre-moistened towelette, while reducing dehydration of the opened towelette pouch within the dispenser. Feed slit adaptations in the lid provide for selective tearability of individual towelette portions from the roll. The dispenser is adapted to provide a low center of gravity, and the base of the dispenser can cooperatingly engage a wall-type holder. The towelette roll contains a leader adapted for ease of feeding through the feed slot upon first use.

Abstract: An internal combustion piston engine employs a stratified charge. Separate carburetor throats are provided for directing rich air-fuel mixture to a prechamber and lean air-fuel mixture to a main combustion chamber. The rich mixture is heated by the engine exhaust gases and then delivered to the prechamber. A spark plug ignites the rich mixture and causes a torch flame to project laterally through a torch slot in the prechamber wall into the main combustion chamber to ignite the lean mixture contained therein. In this way, the amount of unwanted emissions such as carbon monoxide may be reduced in the exhaust gases discharged into the atmosphere.

Abstract: A high power, cw, high pressure, electrically excited flowing gas laser is disclosed wherein a laser excitation transverse to the direction of gas flow is initiated by an electron beam perpendicular to the gas flow direction. The electron beam has a cross-sectional area conforming substantially to that of the excitation region and is especially profiled to have a cross-sectional electron density which varies as a function of distance along the direction of gas flow from substantially a minimum value at the upstream and downstream extremities of the excitation region to a maximum value approximately midway along the excitation region. This profiling, which may be achieved by tapered width apertures in either an electron beam window support member or in an electron gun grid, provides an appropriate heat input to the laser gas to minimize gas density variations in the excitation region and thereby optimize the beam quality of the generated laser beam.

Abstract: The screw tightening tool has an electrical control system and a method of determining the value of the tightening parameter which is sufficient for tightening any fixing elements to a given tightness. The parameter can vary from one fixing element to another. The tightening process of the fixing element is terminated as a function of a variable value of the specific tightening parameter. It consists of a driven tool which transmits the input characteristics to the fixing element. The input characteristics are sensed and converted into signals. These signals are used to establish a final switch-off parameter, based on the ratio between the final value of the tension required in the fixing element and a variation in tension in the fixing element. The tool is switched off when the required value of tension is achieved.
