  • Patent number: 4899765
    Abstract: Cigarette rods are manufactured at high rates of speed using a cigarette making machine having a tongue which is equipped such that water is continuously fed therethrough in order to exit the surface of the tongue which contacts a tobacco filter stream passing through the garniture region of the cigarette making machine. The process of introducing water through the tongue during a cigarette making operation allows the manufacturer to produce a continuous cigarette rod of controlled integrity. For example, cigarettes of controlled density and firmness, and having very low amounts of hard spots, soft spots and loose ends, can be manufactured. The process provides for the manufacture of cigarettes at high speeds, and for the manufacture of cigarettes having high filling capacity tobacco blends. For example, cigarettes having blends comprising relatively high levels of volume expanded tobacco can be manufactured efficiently and effectively.

  • Patent number: 4441806
    Abstract: Document exposure apparatus for a document copier is disclosed. Selectively, either the front or both sides of a document may be copied. Automatic transport apparatus first passes the document by a first optical scanning station from which signals representative of the front side of the document are obtained by a scanner. The document is then transported so as to engage a rotating drum. When only front side copying is desired, fingers of a solenoid actuated gate remove the document from the drum after a partial revolution is made and the document is passed to a receiving tray. When it is desired to copy both sides of a document, the gate is first lifted from the drum allowing the document to continue rotation with the drum so as to present the back side of the document, with the document traveling in the opposite direction, to a second scanning station to which the scanner has now moved, for copying the back side of the document.

  • Patent number: 4357613
    Abstract: An ink jet printer includes a charge decoupling device which permits fluid flow of electrically conductive fluid between a high voltage electrode and a grounded fluid reservoir while presenting a high impedance electrical path therebetween. The charge decoupling arrangement includes a nonconductive casing defining an interior casing cavity which is separated into an upper and a lower portion by means of a perforated plate extending horizontally across the cavity. A plurality of drop stabilizers are mounted adjacent associated ones of the perforations to define downwardly extending capillary fluid paths from the perforations into the lower portion of the cavity to form fluid drops which drip off of the bottoms of the stabilizers. The break up of the fluid into drops provides the high impedance path through the charge decoupling device, thus ensuring that the deflection electrode arrangement and the catchers are substantially electrically isolated.

  • Patent number: 4333833
    Abstract: An in-line contactor adapted to bring about intimate contact between a disinfectant and a wastewater stream to produce a reaction between the disinfectant and pathogens effecting kills in a manner minimizing unwanted side effects. The wastewater stream is pumped through the successive stages of the contactor, the first of which is an input section having a converging nozzle that projects the stream at high velocity into a throat. The throat feeds the stream in a highly turbulent state through a mixing section, the resultant vacuum created within the throat acting to draw a disinfectant such as aqueous or gaseous chlorine from a disinfectant supply into the mixing section where it is thoroughly intermingled with the turbulent stream before the stream is discharged from the contactor through a diverging pressure-recovery output section.
