Abstract: A liquid dispensing nozzle has a bellows secured to its body and disposed in spaced surrounding relation to its spout to form vapor return means therebetween. Sealing means, which can be integral with the bellows or separate therefrom, is disposed in surrounding relation to the spout so as to be movable relative thereto. The spout has a retainer thereon between the free end of the spout and the sealing means. The retainer has a curved surface, which is preferably spherical, on its end for engagement with a sealing surface of the sealing eans to form a seal therebetween to seal the vapor return means formed between the bellows and the spout from the atmosphere when the spout is not disposed in a fill pipe of a vehicle tank to be filled.

Abstract: A mechanism for operating an instrument such as, for example, a gauge primarily for measuring pressure having a diaphragm the opposite faces of which are subject to a pressure differential so that the center moves in response to such differential. The diaphragm movement is transmitted to an array of bar magnets that moves in a substantially rectilinear translative movement in response to diaphragm movement. A rotary magnet spaced from the path of movement of the array of bar magnets and within the composite magnetic field produced by the array rotates as the array is translated, the angular rotation being a predetermined mathematical or empirical function of the amount of translation and built into the array. The mathematical function is achieved by proper choice of magnet dimensions and placement thereof relative to one another. Rotation of the rotor is used to drive a pointer indicator over a scale to indicate pressure.

Abstract: A warp resistant fire door structure is disclosed, which includes a frame and a pair of front and back panels mounted thereon. The panels are secured permanently to the frame only at points adjacent their lateral edges. At other points, the panels are heat releasably bonded to the frame to be able to expand and contract relative to the frame in the presence of ambient temperature extremes.

Abstract: The invention forming the subject matter hereof comprises a flow measuring device for use in fluid-carrying conduits characterized by an elongate housing member including a longitudinally-extending slot communicating the interior thereof and opening upstream, a first tubular impact probe mounted within the housing and having a port in the wall thereof opening in a direction other than toward the slot in the latter, and a second tubular suction probe mounted inside the housing alongside the impact probe, the suction probe also including a port in the wall thereof facing downstream.

Abstract: Filter assembly, particularly for handling liquids at elevated temperatures. There is disclosed a filter assembly wherein the headers supplying filter liquid to the filter units and receiving filtrate therefrom are arranged in a first zone, all the filter units are arranged in a second zone, and at least some of the actuators for the backwash controlling valves extend outwardly of and away from both of said zones to avoid the heat associated with said zones. A heat shield may then be positioned between said valve actuators and the rest of the filter assembly, which heat shield may, if desired, be one wall of a heat retaining box enclosing the headers and filter cylinders.

Abstract: An hydraulic jack for an elevator installation comprises a pair of cylinders and a common plunger. One cylinder is fixedly mounted in a vertical position in a hoistway; while one end of the plunger is mounted within the fixed cylinder for vertical reciprocating movement therein. The other cylinder, which carries an elevator cab up and down in the hoistway, is slidably mounted about the other end of the plunger for vertical reciprocating movement thereon.

Abstract: An hydraulic elevator installation for vertically transporting an elevator cab up and down in a hoistway comprises a piston fixedly mounted in a vertical position in the hoistway and a lifting frame for carrying the elevator cab. The lifting frame includes a cylinder forming a vertical support member of the lifting frame and slidably mounted about the piston for vertical reciprocating movement thereon.

Abstract: An elevator rail mounting system for positioning a pair of elevator guide rails, capable of centering an elevator cab therebetween, in a hoistway comprises a U-shaped bracket, mountable in the hoistway an adjustable distance from the entrance side thereof, for fixing the angular relationships of and distances between the guide rails, a landing sill and a hall door frame to insure a constant running clearance between the elevator cab and the landing sill and to maintain the proper alignment of the elevator cab and the hall door frame. The U-shaped bracket includes a horizontally and vertically adjustable cross member mounted from the entrance side of the hoistway substantially adjacent and parallel thereto.

Abstract: The assembly includes an outer race secured in one of the spindle bores in the revolving head of an automatic screw machine, and an inner race or sleeve which is adjustably secured to the associated work spindle. A plurality of roller bearing elements mounted in the outer race roll on the periphery of the sleeve to rotatably journal the forward end on the spindle in the head. The sleeve has a tapered, truncated-conical bore which mates with a complimentary taper formed on the outer periphery of the spindle. By rotating an adjusting nut on the spindle, the sleeve can be driven axially on the spindle in a direction which causes it to be slightly expanded radially to take up any undesirable radial play in the bearing assembly.
