Title: Gravity outlet
Inventor: BALTZ DWAIN
IPC: B61D7/20
Filed: 1994-04-22
Abstract: Abstract of the Disclosure A sliding gate type gravity outlet (10) is for use on railcars (C) for discharging a lading.  A pan assembly (12) defines an outlet pan (14) having a flange (18) attached to the discharge opening and sidewalls (20) sloping downwardly from the flange.  A bottom portion of the sidewalls define? a discharge outlet (22) into which lading flows.  An outlet gate (24) is movable relative to the opening to open and close the outlet.  Lading to be discharged bears upon the gate when it is in its closed position.  A rack and pinion gear arrangement (36) is used to move the gate back and forth between these positions, and a rod (62) guides movement of the gate.  The gate sealingly abuts against a seal (32) when the gate is closed to prevent loss of lading.  The guide mechanism sits at an angle (X1) with respect to the outlet, and the gate is set at a second and greater angle (X2) with respect thereto.  As the gate moves from its closed to its open position, it is drawn away from the seal and does not slide over it.  By being drawn away, rather than sliding over the seal, wear of the seal is reduced.

Filed: 1994-05-09
Abstract: The present invention provides for a photoelectric smoke detector comprising a case having mounted therein a circuit board and a smoke detection chamber.  The smoke detection chamber has side walls with openings provided therein for ingress and egress of smoke particles, a top and a bottom.  A photoemitting diode is mounted in a mounting arrangement in the side wall of the smoke detection chamber so that a light beam from the photoemitting diode is transmitted across the smoke detection chamber without directly impinging upon either the top or the bottom surfaces.  The bottom of the smoke detection chamber has an opening therein with a shielding arrangement thereabout open to the chamber, the opening and shielding arrangement being located between the centerline of the smoke detection chamber and the mounting arrangement in the side wall of the chamber.  The circuit board is mounted to overlie the bottom surface and includes a photodiode detector mounted directly thereon and positioned generally in the opening so that it views into the smoke detection chamber through the opening and through the shielding arrangement, the shielding arrangement shielding the photodiode detector from incident light which may be present in the smoke detector chamber while providing for a diverging field of view of the photodiode detector. The diverging field of view of the photodiode detector intersects the light beam of the photoemitting diode to define a detection volume contained within the smoke detection chamber located close to the photoemitting diode and the photodiode detector and spaced from the surfaces of the smoke detection chamber to minimize the effect on the photodiode detector of light from the photoemitting diode which is reflected exterior to the detection volume.
