Abstract: A nuclear fuel element loading system is described which conveys a plurality of fuel rods to longitudinal passages in fuel elements. Conveyor means successively position the fuel rods above the longitudinal passages in axial alignment therewith and adapter means guide the fuel rods from the conveyor means into the longitudinal passages. The fuel elements are vibrated to cause the fuel rods to fall into the longitudinal passages through the adapter means.

Abstract: According to the invention, electrically conductive paths are formed between the coil armor and the core laminations of dynamoelectric machines for inhibiting corona. This is achieved by injecting an uncured, semi-conducting, elastomeric material between the coil sides and the walls of the core slots by way of the air ducts in the core, and thereafter curing the material. The uncured material has a viscosity which enables it to be forced under pressure between the coil sides and slot walls. The cured material has a resistance high enough not to form eddy current paths between laminations and yet low enough to conduct charge from the coil armor to the core. It is also capable of retaining its strength, elasticity, conductivity, etc., and remaining in place between the coils and core under vibrations, coolant flow, electric stresses, repeated temperature changes, etc., for the normal operating life of the machine.

Abstract: A spout for a gasoline nozzle providing vapor control for gasoline vapor produced during the filling of a vehicle tank.

Abstract: A fail-safe interlock system is disclosed for use in conjunction with a truck which has a filler valve for the loading of product, and which eliminates the safety hazard of driving the truck away from a loading facility while a loading hose is still connected to the vehicle's filler valve. Movement of a shield in a direction which permits clear access to the end of the filler valve causes the vehicle's ignition circuit to be broken, thereby preventing driving of the truck while the loading hose is connected to the end of the filler valve; and correspondingly, movement of the shield in the opposite direction to where it at least partially covers the end of the filler valve causes the restoration of the ignition circuit, thereby permitting driving of the vehicle after the loading hose has been safely disconnected.

Abstract: In order to prevent malfunctioning of an automatic liquid fuel dispensing nozzle which is being used for vapor recovery while dispensing, the pressure inside the tank (into which liquid fuel is being dispensed) is used as a reference pressure for the actuating diaphragm of the nozzle cut-off arrangement, rather than using atmospheric pressure for this purpose. Displaced vapors from the tank are directed through a vapor recovery boot having a flexible, exterior cylindrical sleeve and an interior of reticulated material which provides passageways for the vapors to travel through.

Abstract: An apparatus for the pneumatic discharge of containers which are lined with a foil bag which contains a pulverulent mass comprises a tubular connection to the container having an interior sleeve portion opening into the container and providing a rotatable support for a double walled suction tube. The double walled suction tube has an interior end with a central opening into the container and an annular opening which communicates with the space between the walls and which is supplied with an air for the purpose of breaking up the pulverulent mass at the entrance to the central suction. Additional air is supplied through openings in the sleeve to the space surrounding the suction tube and the sleeve advantageously includes an insert at its inner end forming a nozzle-like divergent sections with a flow of air into the container to support the bag against collapse.

Abstract: In a liquid supply nozzle having a nozzle valve opened and closed by the manipulation of an operating lever, a nozzle pipe having an air vent hole near the front discharge end thereof, and an automatic stopping mechanism operating when air supply thereto is shut off by the closure of the air vent hole to close the nozzle valve irrespective of the operation of the operating lever, there is provided a mechanism which normally keeps the air vent hole open but operates when the nozzle is pressed against the rim of a liquid filling inlet designed for supplying a liquid of a kind other than that of the liquid specified for the nozzle to close the air vent hole. As a result of the closure of the air vent hole by this vent hole closing mechanism, the nozzle valve is closed by the automatic fuel supply stopping mechanism even when the operating lever is operated, whereby supplying of the specified liquid into a liquid filling inlet designed for another kind of liquid is effectively prevented.

Abstract: An automatic shut-off nozzle incorporating a vapor recovery system for recovering the displaced vapors from a gasoline storage tank or the like as the tank is being filled by the nozzle wherein the nozzle is automatically shut-off when the pressure within the vapor recovery system increases above a predetermined minimum pressure. The nozzle incorporates a latching mechanism which is releasable in response to the increase in pressure in the vapor recovery system and which is also responsive to a loss of vacuum pressure resulting from the level of the liquid in the storage tank rising above a predetermined level with respect to the nozzle. The nozzle is constructed such that the ambient pressure in the main diaphragm chamber corresponds to the pressure of the vapor recovery line so that the release mechanism for the slide is not as sensitive to the pressure in the gasoline storage tank.

Static electricity grounding during the fueling procedure, which ordinarily is achieved simply by establishing contact between the fueling nozzle and filler pipe, is, in this instance, achieved just as readily, even though the plastic device separates the fueling nozzle and filler pipe, merely upon the projection of the fueling nozzle into the overflow device.

Abstract: A fluid dispensing nozzle, e.g., a nozzle for a gasoline station filling pump, is provided with a trigger retaining mechanism which allows an operator to retain the nozzle trigger member in its operative position by exerting a continuous relatively low manual force in contrast to the relatively high manual force required to operate the trigger member. The trigger member automatically returns to its inoperative position immediately upon release of the manual force on the trigger retaining mechanism. The fluid dispensing nozzle is particularly suitable for use in self-service gasoline filling stations.
