Abstract: A ribbon cassette or cartridge comprising a housing having a hub element supporting a core having a ribbon wound thereon, such as a typewriter or printer ribbon, and adapted to releasably engage said core for rotation thereon. The hub element comprises at least two portions, at least one portion being fixed to the housing of said cassette or cartridge, and at least one other portion which is attached for movement between a locking position, in which it makes frictional engagement with the ribbon core to substantially prevent rotation of said core on said hub element, and a release position in which it is moved out of frictional engagement with said ribbon core to permit rotation of said core on said hub element.

Abstract: Pneumatic nebulizer and method for uniformly introducing variable small amounts of flowable liquid into a gas flow to form a stable dispersion having the appearance of a natural fog and consisting essentially of microscopic liquid particles of said liquid dispersed in said gas. The nebulizer comprises a mixing element for introducing the liquid in uniformly fine amounts into the gas flow. The mixing element, which preferably is a replaceable unitary element comprises two contacting members having conforming surfaces which supportingly contact each other over a substantial portion of the surfaces of each to prevent compression therebetween. At least one shallow liquid passage is provided between the members of the mixing element said passage having an entrance in communication with a liquid supply chamber and having an exit orifice in communication with a gas passage to provide at least one stable liquid orifice for metering uniform predetermined amounts of liquid into a gas flowing through said gas passage.

Abstract: A double check or safety system for recording information of two types on a record sheet, such as a time clock card. One type of information is applied automatically to a first predetermined area of the record sheet when the sheet is inserted into a machine, such as the entrance time and exit time stamped onto the record sheet by a time clock. The other type of information is applied manually by the operator, such as a signature applied by the operator to a second predetermined area of the record sheet associated with the time stamp area.

Abstract: A thin, pressure-sensitive, ink-releasing transfer element such as a ribbon capable of releasing a substantially uniform and intense amount of smudge-resistant ink at least about four times from overlapping impressed areas of the ink layer corresponding to each double image width during high speed printing use on "hammer-impression" high speed typewriters. The thinness of the ribbon is important not only to accommodate a maximum amount of ribbon on the feed spool, but primarily in order to provide a ribbon which is operative in such typewriters to produce images having excellent sharpness, uniform intensity, edge profile and freedom from pick-over, which properties also result from the cooperative nature of the ink and undercoating used on such ribbons.
