Abstract: A two-way safety trip is placed at selected locations along a railway track to demarcate a safety zone within which the travel of a railway vehicle is stopped upon entering the zone and is permitted to continue upon leaving the zone, the safety trip including a bracket for attachment to the track and a trip member selectively mounted upon the bracket in alternate mounting orientations for serving at either boundary of the safety zone.

Abstract: A filling valve for filling a container from a pressurized liquid filled bowl is disclosed. The filling valve includes a housing with a liquid filling orifice through it and a liquid flow valve for opening and closing that orifice. A gas flow tube extends through the liquid flow valve element and projects both above and below it. A pressure responsive piston is supported on the gas flow tube. A cover is located over the gas flow opening at the top of the gas flow tube and includes a closure element ball. A sleeve supports the closure element above the top opening of the tube. A spring holds the closure element off the top opening of the tube. A guide sleeve outside the supporting sleeve is connected with the gas flow tube. A spring biases the supporting sleeve out of the guide sleeve.

Abstract: In machines for filling bottles, liquid passes into a bottle past filling valve sealing sleeve and air exits through a vent tube; the filling valve retainer carries an annular rubber gasket that seals against the lip of the bottle to prevent leakage as the bottle fills; a centering bell is carried on the filling valve retainer and extends over the neck of the bottle; the sealing gasket is secured in the centering bell and the gasket is removed from the filling valve retainer by the removal from the retainer of the centering bell; the centering bell is held to the filling valve retainer by resilient snap-in means.
