  • Patent number: 7665192
    Abstract: A slider is adapted for use with a reclosable fastener for bags containing material. The reclosable fastener includes a first track and a second track. The first track includes a first profile, while the second track includes a second profile. The first and second profiles are releasably engageable to each other. At least one of the first and second profiles has an interior portion. The slider comprises a body that includes a top, a first side, a second side and a separation member on an underside of the top. The separation member is adapted to open and close the fastener and includes a slider finger that extends generally downwardly from the top. The slider finger extends into an interior portion of the first profile so as to assist in removing material trapped in the interior portion of the first profile when closing the reclosable fastener.

  • Patent number: 4621772
    Abstract: An electromagnetic fuel injector has a thin orifice director plate, mounted downstream of the orifice passage defined when the solenoid actuated valve of the injector is in the open position relative to its associated valve seat, for controlling static flow from the injector. The thin orifice director plate is provided with upset angled portions having the flow orifice formed at right angles therethrough to direct the jets of fuel flow, as desired, relative to the axis of the spray tip discharge passage of the injector. Preferably, the length (L) to diameter (D) ratio of each flow orifice is 0.5 or less.
